21/7=q

3=q

hope it helps

27 = 7q + 6

So, q = 3.

Answer:

97.95% of these nuts will meet the specification limits.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The offsetting machine used to make these nuts has been producing nuts with an average locking torque of 8.62 in-lb and variance of 4.49 squared in-lb.

This means that [tex]\mu = 8.62, \sigma = \sqrt{4.49}[/tex]

Torque is normally distributed. If the upper specification is 13.0 in-lb and the lower specification is 2.25 in-lb, what percent of these nuts will meet the specification limits?

The proportion is the p-value of Z when X = 13 subtracted by the p-value of Z when X = 2.25. So

X = 13

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{13 - 8.62}{\sqrt{4.49}}[/tex]

[tex]Z = 2.07[/tex]

[tex]Z = 2.07[/tex] has a p-value of 0.9808.

X = 2.25

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{2.25 - 8.62}{\sqrt{4.49}}[/tex]

[tex]Z = -3.01[/tex]

[tex]Z = -3.01[/tex] has a p-value of 0.0013.

0.9808 - 0.0013 = 0.9795

0.9795*100% = 97.95%

97.95% of these nuts will meet the specification limits.

Answer:

Step-by-step explanation:

Therefore the answer is 27 or more months to depreciate to less than £1200 at a rate of 5% per month.

Depreciation is a phrase that covers two different elements of the same idea: first, the real decline in an asset's fair value, such as the annual decline in the worth of industrial equipment.

Your balance sheet may be broken down into two categories, assets and liabilities, in its most basic form. A company's assets are any possessions that have the potential to provide future financial gain. Your debts to other people are called liabilities. In other words, assets increase your wealth while obligations decrease it.

The value of the motorbike will decrease by 5/100 = 0.05 (or 5%) each month. So, to find out how many months it will take for the value of the motorbike to decrease from £2550 to less than £1200, you need to solve the following equation:

£2550 - (0.05 * x) < £1200

where x is the number of months.

You can re-arrange the equation to solve for x:

x > (2550 - 1200) / 0.05

x > (1350) / 0.05

x > 27

So it will take the motorbike 27 or more months to depreciate to less than £1200 at a rate of 5% per month.

Answer:

5.5; 11.00; 16.50

[tex]E = 5.5h[/tex]

Step-by-step explanation:

Given

The attached table

Solving (a): Complete the table

First, calculate the slope (m)

[tex]m = \frac{E_2 - E_1}{h_2 - h_1}[/tex]

So:

[tex]m = \frac{27.5- 22.00}{5-4}[/tex]

[tex]m = \frac{5.50}{1}[/tex]

[tex]m = 5.50[/tex]

So, the equation of the table is:

[tex]E = m(h - h_1) + E_1[/tex]

[tex]E = 5.5(h - 4) + 22[/tex]

[tex]E = 5.5h - 22 + 22[/tex]

[tex]E = 5.5h[/tex]

When h =1,2,3

[tex]E = 5.5 * 1 = 5.5[/tex]

[tex]E = 5.5 * 2 = 11.00[/tex]

[tex]E = 5.5 * 3 = 16,50[/tex]

Answer: We can set up a system of equations to represent this problem. The first equation represents the total value of the nickels and dimes in terms of the number of nickels and dimes that Nevaeh has:

0.05x + 0.1y = 0.80

The second equation represents the total number of nickels and dimes that Nevaeh has in terms of the number of nickels and dimes that she has:

x + y = 11

To graphically solve this system of equations, we can use the slope-intercept form of the linear equations.

y = -2x + 22

y = -1/2 x + 8

The solution would be the point where the lines intersect , which x = 4, and y = 7 .

So she has 4 nickels, and 7 dimes.

The only option that is not a compound event is; (2) pulling a king out of a deck of cards

Compound probability is defined as a mathematical term that relates to the likeliness of two independent events occurring.

Thus, a simple event has only one outcome while  a compound event involves the probability of more than one outcome

1) For a coin to land on heads three consecutive times means that there can only be three possible independent outcome  and so this is a compound event.

2) Pulling a king out of a deck of cards is a simple event and not compound because it has only one outcome.

3) This is a compound event because we are dealing with two independent probabilities.

4) This is a compound event because we are dealing with two independent events which are true or false answers.

We are given:

Time period: 3 days and 18 hours

Energy consumed in given time period: 5400 watt-hours

Converting time to hours:

We know that one day is 24 hours

So, 3 days = 72 hours

Time period = 3 days + 18 hours

Time period = 72 hours + 18 hours      

Time period = 90 hours

Converting to days

Time period = 3.75 days

Watt-hour consumption in a day:

Consumption = 5400 watt-hours / 3.75 days

Consumption = 1440 watt-hours/day

3 + x-2/x-3 -4 ≤ 0

-1 + x-2/x-3 ≤ 0

-(x-3) + x-2/x-3 ≤ 0

x-3 < 0

x < 3, x ≠ 3

x < 3

x<3 is the solution of the equation  3 + (x-2) / (x-3) ≤ 4.

A relationship between two expressions or values that are not equal to each other is called 'inequality.

The given equation can be rewritten as 3 + (x-2) / (x-3) ≤ 4.

To solve for x, we need to multiply both sides by (x-3)

3(x-3) + (x-2) ≤ 4(x-3).
3 + x-2/x-3 -4 ≤ 0

Solve the above equation.

-1 + x-2/x-3 ≤ 0

-(x-3) + x-2/x-3 ≤ 0

1/x-3 ≤ 0

x-3 < 0

x < 3

Answer:

the rate at which the temperature drops

the day of the week

Step-by-step explanation:

Since we can choose the number of hour, it is dependent on us.

If we set time = 2, then it would 5 x 2 = 10 degree

Similarly, if we change time, the temperature changes. Thus, it is dependent.

Temperature is dropping at a rate of five degrees per hour.

If t = 1, T = 5*1 = 5°, rate = 5

if t = 2, T = 5*2 = 10°, rate = 5

if t = 3, T = 5*3 = 15°, rate = 5

Notice that rate doesnt change, even the temperature and time changes.

Thus, rate is independent.
