Answer: x = 8

Step-by-step explanation:

This is a very, very, very simple algebra problem. I assume you know the basics of algebra.

First, move 8 to the other side:

3x = 24

divide by 3 on both sides

x = 8

There! Would it kill you to give me a quartic question to spice my life up?

Solution:
Say you have a triangle that is 2.5 by 1
The Number that comes first is the base and there’s only one bass and there’s two sides in those size are 1 so 1×2 is 2+2.5=4.5 so all you’re doing is adding up all the sides together on any shape

a study is planned to compare the proportion of men who dislike anchovies with the proportion of women who dislike anchovies. th
e-lub [12.9K]

Answer:

d. No because n·(1 - \hat p) = 8.96 is less than 10

Step-by-step explanation:

Question options;

a. Yes because the sample sizes of both groups are greater than 5

b. Yes, because in both cases n·\hat p > 10

c. Yes, because we know that the population is evenly distributed

d. No, because the n·(1 - \hat p) is less than 10

Explanation;

The given data are;

The number of men in the sample of men, n₁ = 41

The proportion of men who dislike anchovies, \hat p_1 = 0.67

The number of women in the sample of women, n₂ = 56

The proportion of men who dislike anchovies, \hat p_2 = 0.84

The assumptions for an analysis of the difference between means using a T-test are;

1) The data should be from a random sample of the population

2) The variables should be approximately normal (n·\hat p ≥ 10, and n·(1 - \hat p) ≥ 10)

3) The scale of the data is a continuous ordinance scale

4) The sample size should be large

5) The sample standard deviations should be approximately equal

From the requirement for normality, we have;

For the sample of men, n₁·\hat p₁  = 41 × 0.67 = 24.47 > 10

n₁·(1 - \hat p₁) = 41 × (1 - 0.67) = 13.53 > 10

For the sample of women, n₂·\hat p₂  = 56 × 0.84 = 47.04 > 10

n₂·(1 - \hat p₂) = 56 × (1 - 0.84) = 8.96 < 10

Therefore, the for n₂·(1 - \hat p₂), the sample does not meet the requirement for normality

The correct option is d. No because n₂·(1 - \hat p₂) = 8.96 is less than 10

In Belmont it snowed 1 3/8 inches in the morning and 4 3/8 inches in the afternoon . What was the total amount of snowfall?
Alja [10]
<h2>Answer:</h2>

5 3/4 inches

<h2>Step-by-step explanation:</h2><h3>Known :</h3>
  • It snowed 1 3/8 in the morning
  • It snowed 4 3/8 in the morning

<h3>Asked :</h3>
  • The total amount of the snowfall

<h3>Solution :</h3>

We can add the amount of snowfall in Belmont in the afternoon and in the morning to find the total amount of snowfall.

4 3/8 + 1 3/8

= (4 + 1) + (3/8 + 3/8)

= 5 + 6/8

= 5 6/8

= 5 3/4

<h3>Conclusion :</h3>

The total amount of snowfall is 5 3/4 inches

Identify the factor terms by grouping: 4x^3 + 2x^2 – 18x – 9
hram777 [196]
Group terms that have factorable coefficients (like 2&4 and then 9&18)

(4x³ + 2x²) + (-18x - 9)

factor out the like terms
2x²(2x + 1) - 9(2x +1)

parenthesis are the same so you can factor further.. {Like 2x+3x = (2+3)x}

(2x² - 9)(2x+1)

Factored too far they only want Answer C. is the correct one for grouping
