Answer:

30 grapes, because there are half as many meaning grapes have twice the amount of the pears present

Answer:

10 pair of soccer shorts.

Step-by-step explanation:

Let the unknown be x.

Translating the word problem into an algebraic equation, we have;

2/5 yard = 1 pair of short

4 yard = x pair of short

Cross-multiplying, we have;

2x/5 = 4

Multiplying both sides by 5, we have;

2x = 20

x = 20/2

x = 10 pair of soccer shorts.

(-5,-1) is aka -5<x<-1

This means -2 is the largest value you can find.

Perhaps that is if you are on a line graph, or if you are putting this on a line graph put an open circle (○) on -1 and -5 and draw a line in between the numbers. That's also if you are talking about real numbers and not integers this question is a bit too broad for me to actually figure out the true answer.

Answer:

a. 0.0124 = 1.24% probability of stopping the manufacturing when the sample mean is 16 inches.

b. 0.0241 = 2.41% probability of stopping the manufacturing in case the mean is shifted to 16.05 inches.

c. 0.5 = 50% probability of not disturbing the manufacturing if mean shifts to 16.25 inches.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

Assume that the standard deviation of diameter of the rims is 0.3 inches. Samples of 9.

This means that [tex]\sigma = 0.3, n = 9, s = \frac{0.3}{\sqrt{9}} = 0.1[/tex]

a. Calculate the probability of stopping the manufacturing when the sample mean is 16 inches.

Here we have [tex]\mu = 16[/tex]

Higher than 16.25:

This is 1 subtracted by the pvalue of Z when X = 16.25. So

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

By the Central Limit Theorem

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

[tex]Z = \frac{16.25 - 16}{0.1}[/tex]

[tex]Z = 2.5[/tex]

[tex]Z = 2.5[/tex] has a pvalue of 0.9938

1 - 0.9938 = 0.0062

Lower than 15.75:

This is the pvalue of Z when X = 15.75. So

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

[tex]Z = \frac{15.75 - 16}{0.1}[/tex]

[tex]Z = -2.5[/tex]

[tex]Z = -2.5[/tex] has a pvalue of 0.0062

Probability of stopping:

2*0.0062 = 0.0124

0.0124 = 1.24% probability of stopping the manufacturing when the sample mean is 16 inches.

b. Calculate the probability of stopping the manufacturing in case the mean is shifted to 16.05 inches.

Here we have [tex]\mu = 16.05[/tex]

Higher than 16.25:

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

[tex]Z = \frac{16.25 - 16.05}{0.1}[/tex]

[tex]Z = 2[/tex]

[tex]Z = 2[/tex] has a pvalue of 0.9772

1 - 0.9772 = 0.0228

Lower than 15.75:

This is the pvalue of Z when X = 15.75. So

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

[tex]Z = \frac{15.75 - 16.05}{0.1}[/tex]

[tex]Z = -3[/tex]

[tex]Z = -3[/tex] has a pvalue of 0.0013

Probability of stopping:

0.0228 + 0.0013 = 0.0241

0.0241 = 2.41% probability of stopping the manufacturing in case the mean is shifted to 16.05 inches.

c. Calculate the probability of not disturbing the manufacturing if mean shifts to 16.25 inches.

Between 16.25 and 15.75 with [tex]\mu = 16.25[/tex]. This is the pvalue of Z when X = 16.25 subtracted by the pvalue of Z when X = 15.75.

X = 16.25

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

[tex]Z = \frac{16.25 - 16.25}{0.1}[/tex]

[tex]Z = 0[/tex]

[tex]Z = 0[/tex] has a pvalue of 0.5

X = 15.75

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

[tex]Z = \frac{15.75 - 16.25}{0.1}[/tex]

[tex]Z = -5[/tex]

[tex]Z = -5[/tex] has a pvalue of 0

0.5 - 0 = 0.5

0.5 = 50% probability of not disturbing the manufacturing if mean shifts to 16.25 inches.

==============================================================

Explanation:

4:00 p.m. corresponds to x = 16, since 12+4 = 16

You can think of 4:00 p.m. representing 1600 hours in terms of military time.

Locate 16 on the x axis. Draw a vertical line until this vertical line crosses the blue parabola. Check out the diagram below.

From this point of intersection, draw a horizontal line until you move to the y axis. You should be somewhere between y = 60 and y = 90.

A good guess could be 75 since it is the midpoint of 60 and 90. Algebraically we confirm it as such: (60+90)/2 = 150/2 = 75

To be fair, we may not hit the exact middle and may be at y = 70 instead of y = 75. But I think the midpoint is a good estimate considering we don't have all the information.

Luckily 75 is on the list of choices, and the other choices aren't even close. So choice C is likely the answer.

Answer:

12

Step-by-step explanation:

7/9 x 27 - 18 + 1/3 x 27

Express 7/9 ×27 as a single fraction.

7 x 27 / 9 - 18 + 1/3 x 27

Multiply 7 and 27 to get 189.

189/9 - 18 + 1/3 x 27

Divide 189 by 9 to get 21.

21 - 18 + 1/3 x 27

Subtract 18 from 21 to get 3.

3 + 1/3 x 27

Multiply 1/3 and 27 to get 27/3.

3 + 27/3

Divide 27 by 3 to get 9.

3+9

Add 3 and 9 to get 12.

Answer:

a) The margin of error is 0.3643 years.

b) The margin of error is 0.6514 years.

c) INCREASES

Step-by-step explanation:

(a) Find the margin of error for an 85% confidence interval to estimate the mean time a general manager had spent with their current company:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.85}{2} = 0.075[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.075 = 0.925[/tex], so Z = 1.44.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 1.44\frac{4}{\sqrt{250}} = 0.3643[/tex]

The margin of error is 0.3643 years.

(b) Find the margin of error for a 99% confidence interval to estimate the mean time a general manager had spent with their current company:

[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]

That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.575

[tex]M = 2.575\frac{4}{\sqrt{250}} = 0.6514[/tex]

The margin of error is 0.6514 years.

(c) In general, increasing the confidence level the margin of error (width) of the confidence interval.

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

Increase of confidence level -> Increases z -> Increases margin of error.

So Increases is the answer.

Answer:

7662  electronic keyboards

Step-by-step explanation:

Given that,

The number of electronic keyboards sold in Ohio each year is equivalent to six times the average number sold yearly in Alaska.

There are 45,972 electronic keyboards sold each year in Ohio.

We need to find how many are sold in Alaska.

Ohio = 6 (Alaska)

[tex]A=\dfrac{45972 }{6}\\\\A=7662[/tex]

So, 7662  electronic keyboards are sold in Alaska.

Answer:

-24 and 8

8 and -8

Step-by-step explanation:

Let x = -4 and y= 2. Evaluate the expression.

1) 4|y| -4x

Note that |y| acan be +y or -y

4|y| -4x

= 4y - 4x

= 4(-4)-4(2)

= -16 - 8

= -24

If |y| is -y we have

4(-y) -4x

= -4y-4x

= -4(-4)-4(2)

= 4|y| -4x16 - 8

= 8

For the expression

|xy|

= xy

= -4(2)

= -8

If |xy| ix negative

= -(xy)

= -(-4*2)

= -(-8)

= 8

Hence the value is 8 and -8

Answer:

$153.24

Step-by-step explanation:

:/

Answer:

The answer is 45.

Step-by-step explanation:

60% of a number is 54, find the original number

54 ÷ 60%

= 54 ÷ 60/100

= 54 * 100/60

= 90

50% of 90 is

90 * 50%

= 90 * 50/100

= 90 * 1/2

= 45
