Answer:

x = 5

Step-by-step explanation:

Tangents from a specific point are equal in length.

3x - 7 = 18 - 2x

5x - 7 = 18

5x = 25

Clancy has 423 cups of yogurt to share with his friends at a party. Each guest will receive 1 serving of yogurt which is 34 of a

Amanda [17]

According to the number of cups, 564 people can be invited to the party.

Step-by-step explanation:

This is a simple question of cross multiplication

DATA:

1. Total number of cups of yogurt is 423 cups

2. 1 serving = $\frac{3}{4}$ th of a cup

3. Each guest gets $\frac{3}{4}$ of a cup or 1 serving

4. Find out how many guests can be invited to the party,

Cups : People

$\frac{3}{4}$ : 1

423 : p

5. Cross multiply

$\frac{3}{4}$ p = 423 x 1

3p = 423 x 4

p = $\frac{1692}{3}$

p = 564

Therefore, according to the number of cups, 564 people can be invited to the party.

Frank ate 12 pieces of pizza and Dave ate 15 pieces. “I ate

kobusy [5.1K]

Answer:

Frank

Step-by-step explanation:

So If Dave ate ¼ more than Frank, you would need to divide the denominator by the amount of pizzas, so if 12÷4 is 3 he ate three more pizzas than Frank. If we do the same for Frank, ⅕ or 15÷5=3

So the correct answer would be Frank because 12 is less than 15

My apologies if this wasnt explained very well

48% of their readers own a particular make of car. A marketing executive wants to test the claim that the percentage is actually

oksian1 [2.3K]

Answer:

There is no sufficient evidence to support the executive claim

Step-by-step explanation:

From the question we are told that

The population proportion is $p = 0.48$

The sample proportion is $\r p = 0.45$

The sample size is $n = 300$

The level of significance is $\alpha = 0.02$

The null hypothesis is $H_o : p= 0.48$

The alternative hypothesis is $H_a : p \ne 0.48$

Generally the test statistics is mathematically evaluated as

$t = \frac{\r p - p }{ \sqrt{ \frac{p(1 - p )}{n} } }$

=> $t = \frac{0.45 - 0.48 }{ \sqrt{ \frac{0.48 (1 - 0.48 )}{300} } }$

=> $t = -1.04$

The p-value is mathematically represented as

$p-value = 2P(z > |-1.04|)$

Form the z-table

$P(z > |-1.04|) = 0.15$

=> $p-value = 2 * 0.15$

=> $p-value = 0.3$

Given that $p-value > \alpha$ we fail to reject the null hypothesis

Hence we can conclude that there is no sufficient evidence to support the executive claim
