Step-by-step explanation:

The probability of choosing a red marble and a green marble is 21/136 or approximately 0.154.

We must combine the probability of each occurrence occurring in order to determine the likelihood of selecting a red or an even-numbered green marble. Given that there are 14 red marbles in total among the total of 17 marbles, the chance of selecting a red marble is 14/17. Given that there is only one even-numbered green marble among the other 17 marbles, the probability of selecting one is 1/17. The likelihood of selecting a red or an even-numbered green marble is therefore: 14/17 + 1/17 = 15/17.

The likelihood of selecting a red or an even-numbered green marble is therefore 15/17, or roughly 0.882.

We must multiply the likelihood of selecting a red marble by the likelihood of selecting a green marble in order to determine the likelihood of selecting both red and green marbles. There are 16 marbles left after selecting one, including 2 green marbles. The odds of selecting a red stone during the initial draw are 14/17. After a red marble has been selected and is not being changed, the likelihood of selecting a green marble on the subsequent draw is 3/16. The odds of selecting a red marble and a green marble are as follows: (14/17) x (3/16) = 21/136 = 0.154

Step-by-step explanation:

It's simple

The true total distance chained if the measured distance on the ground is 6000 m would be 6001.8 m.

The measured distance on the ground is 6000 m. However, due to the increase in temperature during the surveying, the chain would have expanded, leading to an increase in the measured length.

The coefficient of linear expansion of steel is 8 x 10^-6 per oC. Therefore, for a temperature increase of 45 - 20 = 25 oC, the increase in length of the chain can be calculated as follows:

ΔL/L = αΔT

Substituting the given values, we get:

ΔL/30.00 = (8 x 10^-6) x 25

ΔL = 0.006 m

This means that the actual length of the chain during the surveying was 30.006 m.

To find the true total distance chained, we need to correct the measured distance on the ground for the increase in chain length. Let D be the true total distance chained. Then we have:

D/30.006 = 6000/30.00

Solving for D, we get:

D = 6000 x 30.006 / 30.00

D = 6001.8 m

Therefore, the true total distance chained is 6001.8 m.

The probability of selecting at random, without replacement, two blue marbles is 5/12 i.e. A.

What exactly is probability?

Probability is a measure of the possibility or chance of an event to be occurred. It is a mathematical concept that is used to describe the degree of uncertainty or randomness associated with an event.

The probability of an event is represented by a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain. For example, the probability of rolling a 6 on a fair six-sided die is 1/6, because there is only one way to roll a 6 out of the six possible outcomes.

Now,

Using formula for probability:

P(A and B) = P(A) × P(B|A)

where P(A and B) is the probability of events A and B occurring together, P(A) is the probability of event A occurring, and P(B|A) is the probability of event B occurring given that event A has occurred.

In this case, we want to find the probability of selecting two blue marbles without replacement. Let's break this down into two events:

Event A: Selecting a blue marble on the first draw

Event B: Selecting a second blue marble on the second draw (without replacement)

For Event A, the probability of selecting a blue marble on the first draw is 6/9, since there are 6 blue marbles out of a total of 9 marbles.

For Event B, the probability of selecting a blue marble on the second draw given that a blue marble was selected on the first draw is 5/8, since there are 5 blue marbles remaining out of a total of 8 marbles.

So, using the formula for probability, we have:

P(Event A and Event B) = P(Event A) × P(Event B|Event A)

= (6/9) × (5/8)

= 30/72

= 5/12

Therefore, the probability of selecting at random, without replacement, two blue marbles is 5/12.

Answer: the total direct cost of one item is $0.47.

Step-by-step explanation:

If the packaging employee makes $14 per hour and can package 200 items in one hour, the direct labor cost per item would be:

Direct labor cost per item = Hourly wage rate / Number of items packaged per hour

Direct labor cost per item = $14 / 200

Direct labor cost per item = $0.07

The direct material cost per item is given as $0.40.

Now we can calculate the total direct cost per item:

Total direct cost per item = Direct labor cost per item + Direct material cost per item

Total direct cost per item = $0.07 + $0.40

Total direct cost per item = $0.47

The x-values of the points of intersection are x = 0, x = 3, and x = -2.

A point of intersection is a point where two or more lines, curves, or surfaces intersect or cross each other. In other words, it is the point where two or more objects coincide. For example, in a two-dimensional plane, the point of intersection of two lines is the point where the two lines cross each other.

In the given question,

To find the x-values of the points of intersection, we need to solve the equation 2x³ - x² - 7x = x² + 5x.

Simplifying this equation, we get:

2x³ - 2x² - 12x = 0

2x(x² - x - 6) = 0

2x(x - 3)(x + 2) = 0

So, the x-values of the points of intersection are x = 0, x = 3, and x = -2.

a. A = -2, B = 0, C = 3

b. To set up integrals to find the area of the regions, we need to determine which function is on top in each region. The boundary points give us the values of x for which the functions intersect and change positions.

The region between A and B is bounded by y = x² + 5x on top and y = 2x³ - x² - 7x on the bottom, so the integral for this region is:

∫ from A to B of [x² + 5x - (2x³ - x² - 7x)] dx

The region between B and C is bounded by y = 2x³ - x² - 7x on top and y = x² + 5x on the bottom, so the integral for this region is:

The 99% confidence interval estimate of the population proportion p is (0.5323, 0.7877) to 4 decimal places.

What is confidence interval?

A confidence interval is a range of values calculated from a sample of data that is used to estimate an unknown population parameter with a certain level of confidence.

1.To construct a 99% confidence interval estimate of the population proportion p, we can use the following formula:

CI=[tex]$\hat{p}$[/tex]±[tex]\item $z_{\alpha/2}$[/tex]×[tex]\sqrt{\frac{\hat{p}(1-\hat{p})}{n} }[/tex]

where:

[tex]$\hat{p}$[/tex] is the sample proportion (x/n)

[tex]\item $z_{\alpha/2}$[/tex] is the critical value of the standard normal distribution at the 99% confidence level, which is 2.576

n is the sample size

Substituting the given values, we have:

[tex]$\hat{p}$[/tex] = x/n = 66/100 = 0.66

[tex]\item $z_{\alpha/2}$[/tex] = 2.576 (from the standard normal distribution table or calculator)

n = 100

Plugging these values into the formula, we get:

CI = 0.66 ± 2.576 * [tex]\sqrt{(0.66)\frac{(1-0.66)}{100}}[/tex]

CI = 0.66 ± 0.1277

Therefore, the 99% confidence interval estimate of the population proportion p is (0.5323, 0.7877) to 4 decimal places.

2.To estimate the proportion of all Americans that have cats as pets with 95% confidence, we can use the following formula:

CI=[tex]$\hat{p}$[/tex]±[tex]\item $z_{\alpha/2}$[/tex]×[tex]\sqrt{\frac{\hat{p}(1-\hat{p})}{n} }[/tex]

where:

[tex]$\hat{p}$[/tex] is the sample proportion (0.372)

[tex]\item $z_{\alpha/2}$[/tex] is the critical value of the standard normal distribution at the 95% confidence level, which is 1.96

[tex]\item $n$[/tex] is the sample size (710)

Substituting the given values, we have:

​CI=0.372±1.96×[tex]\sqrt{0.372\frac{(1-0.372)}{710} }[/tex]

CI=0.372±0.0325

Therefore, the 95% confidence interval estimate of the proportion of all Americans that have cats as pets is [tex]$(0.3395, 0.4045)$[/tex] to 4 decimal places.

Expressing this in interval notation, we get [tex](33.95$, $40.45$)$[/tex] to 2 decimal places as a percentage.

Thus, we can say with 95% confidence that the proportion of all Americans that have cats as pets is between 33.95% and 40.45%.

3.To determine the sample size required to estimate the population proportion with a margin of error no larger than 0.04 and a 95% confidence level, we can use the following formula:

[tex]n=(\frac{z_{\alpha/2}}{E} )^2[/tex]×[tex]\hat{p}$(1-$\hat{p}$)[/tex]

where:

[tex]\item $n$[/tex] is the required sample size

[tex]\item $z_{\alpha/2}$[/tex] is the critical value of the standard normal distribution at the 95% confidence level

[tex]\item $E$[/tex] is the margin of error

[tex]$\hat{p}$[/tex] is the sample proportion

Substituting the given values, we have:

[tex]n=(\frac{1.96}{0.04} )^2[/tex]×[tex]0.1161[/tex][tex](1-0.1161)[/tex]

Rounding up to the nearest whole number, we get:

n=476

Therefore, the required sample size to estimate the population proportion with a margin of error no larger than 0.04 and a 95% confidence level is 476.

4.To determine the sample size required to estimate the population proportion with a margin of error no larger than 0.05 and a 90% confidence level, we can use the following formula:

[tex]n=(\frac{z_{\alpha/2}}{E} )^2[/tex]×[tex]\hat{p}$(1-$\hat{p}$)[/tex]

where:

[tex]\item $n$[/tex] is the required sample size

[tex]\item $z_{\alpha/2}$[/tex] is the critical value of the standard normal distribution at the 90% confidence level, which is 1.645

[tex]\item $E$[/tex] is the margin of error, which is 0.05

[tex]$\hat{p}$[/tex] is the sample proportion, which is 21/126 = 0.1667

Substituting the given values, we have:

[tex]n=(\frac{1.645}{0.05} )^2[/tex]×[tex]0.1167[/tex][tex](1-0.1167)[/tex]

n=145.9198

Rounding up to the nearest whole number, the government official should take a sample size of 146 to achieve his desired margin of error.

Answer:2.75 gallons of water

Step-by-step explanation:

Answer:

One gallon is equal to 16 cups of water.

To find out how many gallons are in 44 cups of water, we can divide 44 by 16:

44 cups ÷ 16 cups/gallon = 2.75 gallons

Therefore, 44 cups of water is equal to 2 and 3/4 gallons.

Step-by-step explanation:

1. Recall that 1 gallon is equal to 16 cups of water. Therefore, to find how many gallons are in 44 cups of water, we can set up a proportion:

1 gallon / 16 cups = x gallons / 44 cups

2. To solve for x, we can cross-multiply and simplify:

16x = 1 * 44

16x = 44

x = 44 / 16

x = 2.75

3. The result of 2.75 gallons represents the equivalent amount of water in gallons. To express this answer as a whole number or mixed number, we can observe that 2.75 is equal to 2 and 3/4:

2.75 = 2 + 0.75

2.75 = 2 + 3/4

Therefore, 44 cups of water is equal to 2 and 3/4 gallons.

(a) Positive derivative interval: From x = -∞ to x = -4, and from x = 0 to x = 3.

(b) Negative derivative interval: From x = -4 to x = 0, and from x = 3 to x = ∞.

(c) x-value(s) where derivative equals zero: At x = -3 and x = 2.

(d) x-value(s) where derivative does not exist: At x = -4 and x = 3.

To find the intervals where the derivative of the function is positive, negative, or equals zero, we first need to find the critical points by setting the derivative equal to zero and solving for x. We can see from the graph that there is only one critical point at x = -2. We then test each interval between the critical points and endpoints to determine if the derivative is positive or negative.

From x = -infinity to x = -2, the derivative is negative. From x = -2 to x = 3, the derivative is positive. From x = 3 to x = infinity, the derivative is negative. Therefore, the answer is (a) the derivative is positive on (-2, 3); (b) the derivative is negative on (-infinity, -2) and (3, infinity); (c) the derivative equals zero at x = -2; (d) the derivative exists for all x.

The mass of substance left after 6 days is 9 g

The mass of substance left, N is given by

N = N₀exp(-λt) where λ = decay constant and N₀ = initial mass of substance present = 24 g and t = time

Also, λ = 0.693/t' where t' = half-life of iodine = 8 days

So, λ = 0.693/t'

λ = 0.693/8

λ = 0.086625/day

Since the mass of substance left is N = N₀exp(-λt) and we require the mass of substance after t = 6 days,

N = N₀exp(-λt)

N = 16 gexp(-0.086625/day × 7 days)

N = 16 gexp(-0.606375)

N = 16 g × 0.5453

N = 8.72 g
