Answer:

73 Papers

Step-by-step explanation:

Let's start by finding out how many papers Mrs. Thiel has already graded.

56 + 49 = 105

Now, let's subtract how many papers she has already graded from how many she has to grade in total.

178 - 105 = 73

So, Mrs. Thiel has to grade 73 papers this evening.

Answer:

Area = 64 cm²

Step-by-step explanation:

To find the area, we have to follow some steps:

=> Step 1: Make the bases similar:

Since we have 2 bases given 6 and 10 we have to come up with a third base by finding their average:

(6 + 10) / 2

(16) / 2

8

So now that we know our base,

=> Our second step is to multiply the base we found by the height of the trapezoid:

Area = common base * height

Area = 8 * 8

Area = 64 cm²

Hope this helps!

[tex]Area = 3846.5cm^2[/tex]

Step-by-step explanation:

Given

[tex]d = 35cm[/tex]

[tex]\pi = 3.14[/tex]

Required

The area of the ball

A soccer [tex]ball[/tex]has the shape of a [tex]sphere[/tex]. So, the area is:

[tex]Area = 4\pi(\frac{d}{2})^2[/tex]

So, we have:

[tex]Area = 4 * 3.14 * (\frac{35}{2})^2[/tex]

[tex]Area = 4 * 3.14 * (17.5)^2[/tex]

Using a calculator, we have:

[tex]Area = 3846.5cm^2[/tex]

Step-by-step explanation:

it just is and omni calculator said so

Answer:

a) 0.3483 = 34.83% probability that 369 or more of the 1478 adults have sleepwalked.

b) 369 < 403.4, which means that 369 is less than 2.5 standard deviations above the mean, and thus, a result of 369 is not significantly high.

c) Since the sample result is not significant, it suggests that the rate of 24.5% is a good estimate for the percentage of people that have sleepwalked.

Step-by-step explanation:

We use the normal approximation to the binomial to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

A result is considered significantly high if it is more than 2.5 standard deviations above the mean.

Normal probability distribution

Problems of normally distributed distributions can be solved using 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.

When we are approximating a binomial distribution to a normal one, we have that [tex]\mu = E(X)[/tex], [tex]\sigma = \sqrt{V(X)}[/tex].

Assume that 24.5% of people have sleepwalked.

This means that [tex]p = 0.245[/tex]

Sample of 1478 adults:

This means that [tex]n = 1478[/tex]

Mean and standard deviation:

[tex]\mu = 1478*0.245 = 362.11[/tex]

[tex]\sigma = \sqrt{1478*0.245*0.755} = 16.5346[/tex]

a. Assuming that the rate of 24.5% is correct, find the probability that 369 or more of the 1478 adults have sleepwalked.

Using continuity correction, this is [tex]P(X \geq 369 - 0.5) = P(X \geq 368.5)[/tex], which is 1 subtracted by the p-value of Z when X = 368.5.

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

[tex]Z = \frac{368.5 - 362.11}{16.5346}[/tex]

[tex]Z = 0.39[/tex]

[tex]Z = 0.39[/tex] has a p-value of 0.6517

1 - 0.6517 = 0.3483

0.3483 = 34.83% probability that 369 or more of the 1478 adults have sleepwalked.

b. Is that result of 369 or more significantly high?

362.11 + 2.5*16.5346 = 403.4

369 < 403.4, which means that 369 is less than 2.5 standard deviations above the mean, and thus, a result of 369 is not significantly high.

c. What does the result suggest about the rate of 24.5%?

Since the sample result is not significant, it suggests that the rate of 24.5% is a good estimate for the percentage of people that have sleepwalked.

b. true because the slope is the average  weight of a cookie

c. false because the number of cookies will determine the weight of the box

d. false the box is 1oz and box+1 cookie=1.25 oz so the cookie is 1.25-1= .25oz

e. true if you continue the line until 13 cookies you have about 3.75oz

Answer:

= 15x^9/10

Step-by-step explanation:

Multiply the numbers: 3 . 5 = 15

= 15x^1/2x2/5

Apply exponent rule: a^b . A^c = a^b + c

= 15x^1/2+2/5

1/2 + 2/5 = 9/10

= 15x^9/10
