kramer

Answer:

The claim made by Carter Motor Company is correct.

Step-by-step explanation:

The claim made by the Carter Motor Company about their new sedan, the Libra, is that, it will average better than 24 miles per gallon in the city.

The hypothesis to test this claim can be defined as follows:

H₀: The new sedan will average 24 miles per gallon in the city, i.e. μ = 24.

Hₐ: The new sedan will average better than 24 miles per gallon in the city, i.e. μ > 24.

The test can be performed using a z-distribution or the t-distribution based on the information provided.

It is provided that the conclusion made is to reject the null hypothesis.

The null hypothesis will be rejected when the p-value of the test is less than the significance level or the test statistic value is larger than the critical value.

If the null hypothesis is rejected then it will imply that the new sedan, Libra will average better than 24 miles per gallon in the city.

Thus, concluding that the claim made by Carter Motor Company is correct.

A bag contains 1 red, 1 yellow, 1 blue, and 1 green marble. What is the probability of choosing a green marble, not replacing it

lys-0071 [83]

The probability for choosing green and red is $\frac{1}{12}$

Solution:

Given that , A bag contains 1 red, 1 yellow, 1 blue, and 1 green marble.

We have to find what is the probability of choosing a green marble, not replacing it, and then choosing a red marble?

Now, we know that,

$\text { probability of an event }=\frac{\text { number of favourable outcomes }}{\text { total number of outcomes }}$

So, total possible outcomes = 1 red + 1 yellow + 1 blue + 1 green = 4

$\text { Now, probability for green marble }=\frac{1 \text { green marble }}{4 \text { marbles }}=\frac{1}{4}$

And now, total outcomes will be only 3 as we are not replacing the picked marble.

$\begin{array}{l}{\text { Then, probability for red marble }=\frac{1 \text { red marble }}{3 \text { marbles }}=\frac{1}{3}} \\\\ {\text { Then overall probability }=\frac{1}{4} \times \frac{1}{3}=\frac{1}{12}}\end{array}$

Hence, the probability for choosing green and red is $\frac{1}{12}$

Step-by-step explanation:

25x7=175

175/2=87.5

87.5 would be the area of 1 triangle. There are 4 triangles so

87.5x4=350

20% of what equals 1581.01

Zepler [3.9K]

If you rewrite this phrase to be an equation, with N representing the missing number, it would be:

20% x N = 1581.01 or 0.2N = 1581.01

This equation basically says 20% of what number equals 1581.01.

To get to the answer, divide both sides by 0.2. -->

0.2N ÷ 0.2 = 1581.01 ÷ 0.2 -->
N = 1581.01/0.2
N = 7905.05
