Answer:

A. ⅕

Step-by-step explanation:

[tex] \frac{2}{5} [/tex] ÷ 2 = [tex] \frac{2}{5} * \frac{1}{2} = \frac{1}{5} [/tex]

[tex] \frac{2}{25} [/tex] ÷ 2/5 = [tex] \frac{2}{25} * \frac{5}{2} = \frac{1}{5} [/tex]

[tex] \frac{2}{125} [/tex] ÷ 2/25 = [tex] \frac{2}{125} * \frac{25}{2} = \frac{1}{5} [/tex]

Therefore, the multiplicative rate of change of the function would be ⅕

Answer:

A) At α = 0.05, reject the null hypothesis.

Step-by-step explanation:

Given a p-test value of 0.0436 ;

P-value = 0.0436

Recall :

Decision region :

Reject Null if p value < α

Testing the options :

A) At α = 0.05,

0.0436 < 0.05 (true)

Since p value < α ; Reject the null hypothesis.

B) At α = 0.10,

0.0436 < 0.1

True conclusion is to reject the Null Hypothesis

Hence, option B is incorrect.

C) At α = 0.025, reject the null hypothesis.

0.0436 > 0.025

True conclusion is ; Fail to reject the Null ;

Hence, option C is incorrect

D) At α = 0.05, accept the null hypothesis.

0.0436 < 0.05

True conclusion is ; reject the Null

Hence, option D is incorrect

Answer:

342.29

Step-by-step explanation:

You take away the other decimal places.

The round-up to  2 decimal places of 342.296269789 will be 342.30.

To round up or down of tens place then we need to look at the unit place if it is less than 5 then we need to round down and if it is greater than 5 then we need to round up of tens digit.

In order to round to a hundred, we need to look at the tens digit if it is less than 5 then we round down and if it is 5 or greater than 5 then we will round up.

For example round of 346 will, be350 and round of 344 will be 340

Given the digit,

342.296269789

Now,

The 3rd decimal digit is 6 which is greater than 5

So,

2nd digit will round up since it is 9 so it will round as 10 and gives 1 to the first decimal place.

So,

342.296269789 ⇒ 342.30.

Hence "The round-up to  2 decimal places of 342.296269789 will be 342.30".

Answer:

  A

Step-by-step explanation:

Using m=3, n=5, x2=2, x1=-14, the only match is the first one.

The correct expression for the point on the line is [tex]M=\frac{3}{3+5} (2-(-14))+(-14)[/tex]

The formula for expressing the midpoint of a line is expressed as:

[tex]M=\frac{m}{m+n} (x_2-x_1)+x_1[/tex]

Given the following parameters

m=3,

n=5,

x2=2,

Answer:

The proportion of this group that likes chocolate is 0.625.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Likes sprinkles

Event B: Likes chocolate

25% of your friends who like Chocolate (C) also like sprinkles (S).

This means that [tex]P(A \cap B) = 0.25[/tex]

40% of your friends like sprinkles (S) topping.

This means that [tex]P(A) = 0.4[/tex]

Of the friends who like sprinkles, what proportion of this group likes chocolate

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.25}{0.4} = 0.625[/tex]

The proportion of this group that likes chocolate is 0.625.

Answer:

  (x, y) = (0, -6)

Step-by-step explanation:

Substitute for y in the second equation:

  2x -4(8x -6) = 24

  2x -32x +24 = 24

  -30x = 0

  x = 0

  y = 8·0 -6 = -6

The solution is (x, y) = (0, -6).

Hypothesis test on the proportion of employees, gives an evidence

based conclusion which is consistent with the confidence interval.

Response:

1. The percentage of workers that the news report claims work stress have a negative impact on their personal lives, p = 75%

Number of employees in the sample, n = 100

Number that answered yes = 68

The proportion of the employees that said yes, [tex]\hat p[/tex] = 68 ÷ 100 = 0.68

The z-test formula is; [tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p \cdot q}{n}}}[/tex]

q = 1 - p

Which gives;

[tex]z= \mathbf{\dfrac{0.68-0.75}{\sqrt{\dfrac{0.75 \times (1 - 0.75)}{100}}}} \approx -1.62[/tex]

The p-value ≈ 2 × p(Z < -1.62) = 2 × 0.0526 = 0.1052

The significance level, α = 0.10

Given that the p-value is larger than the significance level, we fail to

reject the null hypothesis, and conclude that as follows;

2. The 90% confidence interval is (0.603272, 0.756728)

The confidence interval indicates that at 90% confidence level, the true

proportion of employees that feel that work stress has a negative

impact on their personal lives is between 0.603272 and 0.756728.
