Step-by-step explanation:

Answer:

See Explanations

Step-by-step explanation:

The steps in the question isn't clear enough, however the question is answerable.

From the question, we understand that one model shows that:

200 is 10 times 20

While the second model shows that

200 is 10 times 2

The first model that says

200 = 10 times 20 makes sense.

This is so, because 200 = 20 * 100

While the other model which says

200 = 10 * 2 is nonsense.

This is so because, 200 ≠ 10 * 2

Answer:

I had the same question and guessed but i got 100% on it. The following snip is the answer

Step-by-step explanation:

The function g(x) has the largest maximum which is −1 option (C) is correct if the equation for the function f(x) is f(x)=−2|x−7|−4.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The function:

f(x) = -2|x - 7| - 4

Plug x = 1

f(1) = -16

Plug x = 2

f(2) = -14

Plug x = 3

f(3) = -12

Plug x = 4

f(3) = -10

From the table:

The function g(x) has the largest maximum which is −1.

Thus, function g(x) has the largest maximum which is −1 option (C) is correct if the equation for the function f(x) is f(x)=−2|x−7|−4.

Answer:

-12

Step-by-step explanation:

a(b - c)

b = 3, c = -3 and a = -2

-2( 3- -3)

-2(3+3)

-2(6)

-12

Answer: -12

Explanation: It's a good idea to get into the habit of

using parenthses when substituting numbers in for variables.

If you have parenthses in your original problem,

change them to brackets as you substitute to avoid confusion.

Since your brackets replace your original parenthses,

your first step will be to simplify what's inside the brackets.

So we have (-2) [(3) - (-3)].

Simplifying inside the brackets, we get 6.

So we have (-2) [(6)].

Multiplying from here, our answer is -12.

Answer:

0.857

Step-by-step explanation:

Given that :

Every seventh person gets a free box of popcorn ; then not getting a free box of popcorn means you're not the 7th person inline.

However, since the order of arrangement is unknown, but one person out of every 7 gets ;

Probability of getting a popcorn is hence ;

p(getting popcorn) = 1/7

Probability of not getting will then be its complement :

Answer:

hard to see a little

Step-by-step explanation:

Answer:

(a) The assumption regarding the distribution of the price of small computers which is necessary to test the analyst’s claim are;

(b) H0: μ ≥ 350; HA: μ < 350

(c) The value of the t-test statistic is -0.263.

(d) At a 5% significance level, the t table gives a critical value of -2.015 at 5 degrees of freedom for the left tailed test.

Step-by-step explanation:

We are given that an analyst comments that the larger companies have a cause for concern since the mean price of these small computers has fallen below $350.

She examines six popular brands of these small computers and records their retail prices as given below:

$322, $269, $373, $412, $299, $389.

(a) The assumption regarding the distribution of the price of small computers which is necessary to test the analyst’s claim are;

(b) Let [tex]\mu[/tex] = population mean price of these small computers

So, Null Hypothesis, [tex]H_0[/tex] : μ ≥ 350    {means that the mean price of these small computers is more than or equal to $350}

Alternate Hypothesis, [tex]H_A[/tex] : μ < 350    {means that the mean price of these small computers has fallen below $350}

(c) The test statistics that will be used here is one-sample t-test statistics because we don't know about the population standard deviation;

                          T.S. = [tex]\frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }[/tex]  ~ [tex]t_n_-_1[/tex]

where, [tex]\bar X[/tex] = sample mean price = [tex]\frac{\sum X}{n}[/tex] = $344

            s = sample standard deviation = [tex]\sqrt{\frac{\sum(X-\bar X)^{2} }{n-1} }[/tex] = $55.89

            n = sample of prices = 6

So, the test statistics = [tex]\frac{344-350}{\frac{55.89}{\sqrt{6} } }[/tex]  ~ [tex]t_5[/tex]

                                 = -0.263

The value of the t-test statistic is -0.263.

(d) Now, at a 5% significance level, the t table gives a critical value of -2.015 at 5 degrees of freedom for the left tailed test.

Since the value of our test statistics is more than the critical value of t as -0.263 > -2.015, so we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region.

Therefore, we conclude that the mean price of these small computers is more than or equal to $350.

Yes... It is in the simplest form..

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Mean (m) = 72

Standard deviation (sd) = 10

Grading cutoff policy:

bottom 5% receive F

next 15% receive D

next 35% receive C

next 30% receive B

A) Give the cutoffs for the grades in this course in terms of standardized scores.

Standardized score for grade cutoff:

Locating the Zscore for the proportions on the z table :

Bottom 5% = 0.05 ; corresponding Zscore = - 1.645

next 15% receive D = (5 +15)% 0.20 ; corresponding Zscore = - 0.84

next 35% receive C = (20+35)% = 0.55 ; corresponding Zscore = 0.13

next 30% receive B = (55 + 30)% = 0.85 ; Corresponding Zscore = 1.04

B) Give the cutoffs in terms of actual total scores.

Recall:

Zscore = (x - m) /sd ; where x = actual score

x = sd*z + m

For F:

10*(-1.645) + 72 = 55.55

For D:

10*(-0.84) + 72 = 63.6

For C:

10*(0.13) + 72 = 73.3

For B:

10*(1.04) + 72 = 82.4

C) Do you think that this method of assigning grades is a good one?

Yes, it is good in terms of expressing scores around the mean such that score below are negative and those above are positive. However, it is a little bit ambiguous.

Answer:

24

Step-by-step explanation:

Given the equation of the regression line :

y = - 20.3 + 0.489s

where ŷ is the predicted science score

s = IQ score

An actual science test score for a student is 52.6 with an IQ of 100.

Find and interpret the residual.

The predicted science test score for a student with an IQ of 100 is :

y = - 20.3 + 0.489(100)

y = - 20.3 + 48.9

y = 28.6

The residual = actual - predicted score

The residual = 52.6 - 28.6 = 24

Hence, the residual is 24 which is the error in prediction made about the actual score.

Answer:

−1.99; The regression line overpredicts the student's science test score.

Answer:

The null hypothesis will not be rejected.

Step-by-step explanation:

The hypothesis for the test is:

H₀: There is no difference between the two population means, i.e. d = 0.

Hₐ: There is a significant difference between the two population means, i.e. d ≠ 0.

Consider the Excel output attached.

The mean of the differences is, [tex]\bar d=-2.75[/tex].

The standard deviation of the differences is, [tex]S_{d}=4.268[/tex].

Compute the test statistic as follows:

[tex]t=\frac{\bar d}{S_{d}/\sqrt{n}}=\frac{-2.75}{4.268/\sqrt{8}}=-1.82[/tex]

The degrees of freedom is, n - 1 = 7.

Compute the p-value as follows:

[tex]p-value=2\cdot P(t_{7}<-1.82)=0.112[/tex]

The decision rule is:

The null hypothesis will be rejected if the p-value of the test is less than the significance level.

p-value = 0.112 > α = 0.02.

The null hypothesis will not be rejected.

Answer:

x=33 and angle=69

Step-by-step explanation:

just got it on a test

Measure of x = 69 degree.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that,

vertex angle = 42 degree

Angle of base angle = (2x + 3)°

Use the knowledge that the sum of the base angles in an isosceles triangle equals 180° minus the vertex angle to find the value of x.

Thus,

Vertex angle is,

(2x + 3)° + (2x + 3)° = 180° - 42°

Base angle + Base angle = 180° - 4x + 6 = 138

4x = 132 x = 33

We substitute x = 33 into (2x + 3)°

To determine the magnitude of each base angle:

Base angle equals (x + 3)°

Base angle = (2 x 33 plus 3).

Angle at base: 69° As a result, each base angle is 69°.
