Answer: 9 and 1/3

Step-by-step explanation:

First of all, you have to find the unit rate. So 28 divided by 2 = 14.

The bird flies at a unit rate of 14 miles in 1 hour.

Next, we need to find out what fraction of an hour is 40 minutes.

How many minutes in an hour? 60... so 40 would be 40/60 of an hour or 4/6 or 2/3 of an hour.

Next, remember the formula D=rt which is distance= rate multiplied by time

We can use this formula here: 14 times 2/3 = 9 and 1/3

Answer:

The integers you seek are:

759, 761, 763, 765

since

759 + 761 + 763 + 765 = 3048.

The fractions [tex]\frac{-2}{5}[/tex] and the fraction [tex]\frac{-4}{10}[/tex] , both are equal [tex]\frac{-2}{5} =\frac{-4}{10}[/tex], which means the "=" sign makes the statement true.

A mathematical relationship between two expressions is called inequality, and it is expressed using one of the following:

"less than or equal to": [tex]\leq[/tex]

"greater than" :>

"greater than or equal to" : [tex]\geq[/tex]

"less than": <

"not equal to": [tex]\neq[/tex]

To compare the fraction, make the denominator of both fractions the same.

Given:

Fraction 1 = [tex]\frac{-2}{5}[/tex]

Fraction 2 = [tex]\frac{-4}{10}[/tex]

To make the same denominator we can multiply by 2 to the numerator and denominator of the fraction 1.

[tex]\frac{-2}{5} =\frac{-2 * 2}{ 5*2}[/tex]

[tex]\frac{-2}{5} =\frac{-4}{10}[/tex]

Hence from the above calculation, the given fractions are equal.

The largest angle in quadrilateral PQRS is angle R with a measure of 150 degrees.

what is quadrilateral?

A quadrilateral is a four-sided polygon, which is a two-dimensional closed shape with straight sides. In other words, a quadrilateral is a geometric figure that has four sides, four vertices, and four angles. The sum of the interior angles of a quadrilateral is always equal to 360 degrees. Examples of quadrilaterals include squares, rectangles, parallelograms, trapezoids, and kites.

From the given information, we have:

angle P = 3p

angle Q = 4q

angle R = 5r

Since PQRS is a cyclic quadrilateral, the sum of opposite angles is equal to 180 degrees. Therefore, we have:

angle P + angle R = 180 degrees

3p + 5r = 180 degrees

Similarly, we have:

angle Q + angle S = 180 degrees

4q + S = 180 degrees

S = 180 - 4q

To find the largest angle, we need to find the largest angle measure among angles P, Q, R, and S.

Let's substitute the expression for S in terms of q into the equation for angle Q and simplify:

angle Q = 4q

angle Q + angle S = 180 degrees

4q + (180 - 4q) = 180 degrees

4q - 4q + 180 = 180 degrees

180 = 180 degrees

This equation is true, but it does not provide any information about the largest angle in PQRS.

Let's now substitute the expressions for angles P, Q, and R in terms of p and r into the equation for angle P + angle R = 180 degrees:

3p + 5r = 180 degrees

We want to find the largest angle, so we need to find the largest value of p or r that satisfies this equation. One way to do this is to try different values of p and r that satisfy the equation and see which one yields the largest value for angle P or angle R.

Let's try p = 10 and r = 30:

3p + 5r = 3(10) + 5(30) = 150

This satisfies the equation, so we can calculate angle P and angle R:

angle P = 3p = 30 degrees

angle R = 5r = 150 degrees

Therefore, the largest angle in quadrilateral PQRS is angle R with a measure of 150 degrees.

The probability of selecting a football card and then a basketball card is 0.16 or 16%. The probability of selecting a football card and then a basketball card can be calculated by multiplying the probability of selecting a football card on the first draw and the probability of selecting a basketball card on the second draw.

Since the first card is replaced before the second draw, the probability of selecting a football card or a basketball card remains the same on both draws.

The probability of selecting a football card on the first draw is 2/10, or 0.2, since there are 2 football cards in a total of 10 cards in the bag. The probability of selecting a basketball card on the second draw is 8/10, or 0.8, since there are 8 basketball cards left after the first draw.

Therefore, the probability of selecting a football card and then a basketball card can be calculated as follows:

P(Football and Basketball) = P(Football on 1st draw) x P(Basketball on 2nd draw)

= (2/10) x (8/10)

= 0.16

So, the probability of selecting a football card and then a basketball card is 0.16 or 16%.

The solution to the system of equations is p = 4 and q = 2

The substitution method is a way to solve a system of linear equations. In this method, we solve one of the equations for one of the variables, and then substitute the resulting expression into the other equation. This produces a new equation with one variable, which we can then solve for its value. Once we know the value of one variable, we can substitute it back into one of the original equations to find the value of the other variable.

To solve the system of equations using the method of substitution, we need to solve one of the equations for one of the variables, and then substitute the resulting expression into the other equation. We can start by solving the second equation for p:

p + 2q = 8

p = 8 - 2q

Now we can substitute this expression for p in the first equation:

2p - 3q = 2

2(8 - 2q) - 3q = 2

16 - 4q - 3q = 2

16 - 7q = 2

-7q = -14

q = 2

We can now substitute q = 2 into the expression we found for p:

p = 8 - 2q

p = 8 - 2(2)

p = 4

Therefore, the solution to the system of equations is p = 4 and q = 2.

Samantha needs to mix 10 milliliters of the 40% alcohol solution with 90 milliliters of the 60% alcohol solution to create 100 milliliters of a 58% solution.

Let x be the number of milliliters of the 40% alcohol solution that Samantha needs to mix, and let y be the number of milliliters of the 60% alcohol solution. Since Samantha needs to create 100 milliliters of a 58% solution, we can write the following system of equations:

x + y = 100 (equation 1: total volume)

0.4x + 0.6y = 0.58(100) (equation 2: alcohol concentration)

In equation 1, we see that the total volume of the resulting mixture must be 100 milliliters. In equation 2, we convert the concentration of the 58% solution into a decimal and set it equal to the weighted average of the concentrations of the two solutions.

We can solve this system of equations to find the values of x and y:

x + y = 100

0.4x + 0.6y = 58

Multiplying the first equation by 0.4, we get:

0.4x + 0.4y = 40

Subtracting this equation from the second equation, we get:

Answer:

x = -4,

y = -1

Step-by-step explanation:

{-3x - 8y = 20,

{-5x + y = 19;

Make x or y the subject from either the 1st or the 2nd equation (I chose to make x the subject from the 2nd equation, because after division, the numbers can be written as a finite decimal fraction):

-5x = 19 - y / : (-5)

x = -3,8 + 0,2y

Replace x in the 1st equation with its value from the 2nd one (the underlined expression):

-3(-3,8 + 0,2y) - 8y = 20

Multiply every term inside the bracket by the term on the outside:

11,4 - 0,6y - 8y = 20

Collect like terms and add them together:

-8,6y = 20 - 11,4

-8,6y = 8,6 / : (-8,6)

y = -1

y = -1x = -3,8 + 0,2 × (-1) = -4

The probability that the mean battery life would be greater than 1173.8 minutes is 0.9588

We can solve this problem using the central limit theorem, which tells us that the distribution of sample means from a population with a known variance becomes approximately normal as the sample size increases.

The standard error of the mean can be calculated as

SE = σ / sqrt(n)

where σ is the population standard deviation, n is the sample size

Here, we are given that the population variance is 8100, so the population standard deviation is the square root of 8100, which is 90.

SE = 90 / sqrt(72) = 10.6066

Next, we need to standardize the sample mean using the z-score formula

z = (X - μ) / SE

where X is the sample mean, μ is the population mean.

Here, the population mean is given as 1192 minutes and the sample mean we are interested in is 1173.8 minutes.

z = (1173.8 - 1192) / 10.6066 = -1.7356

We want to find the probability that the sample mean is greater than 1173.8 minutes. Since we have a negative z-score, we need to find the area to the right of this value on a standard normal distribution. We can use a z-table or a calculator to find this probability.

Using a standard normal distribution table, we find that the area to the right of z = -1.7356 is 0.9588.
