$y = \cfrac{2}{3}x~~ - ~~6~\hspace{10em} (\stackrel{x}{?}~~,~~\stackrel{y}{0}) \\\\\\ 0=\cfrac{2}{3}x~~ - ~~6\implies 6=\cfrac{2x}{3}\implies 18=2x\implies \cfrac{18}{2}=x\implies 9=x$

In a large population, 76% of the households have cable tv. A simple random sample of 225 households is to be contacted and the

notsponge [240]

0.017559

It is given that:

Probability of Households Having cable TV, p₀ = 76% = 0.76

Therefore,

The probability that the Households not having cable TV = 1 - 0.76 = 0.24

Sample size, n = 225 households

sample proportions is less than 82% i.e p = 0.82

Now,

The standard error, SE = $\sqrt{} \frac{0.76(1-0.76)}{225}$

= 0.02847

Z = $\frac{0.82-0.76}{0.02847}$

Z = 2.107

therefore, P(sample porportions < 0.82) = P(Z < 2.107)

now from the p value from the Z table we get P(sample porportions < 0.82) = 0.017559

Answer:

-8

Step-by-step explanation:

if you sub in 8 as the value for y, you get

-4x - 8 = 24

add 8 on both sides to simplify

-4x = 32

divide both sides by -4

x = -8

Justin bought some yarn from his Favorite craft store. He can make one score for 3/5 of a ball of yarn. If he purchases 15 balls

Svet_ta [14]

Justin can make 25 scraves with 15 balls of yarn

<h3><u>Solution:</u></h3>

Given that Justin can make one scarve for 3/5 of a ball of yarn

He purchases 15 balls of yarn

<em><u>To find: number of scarves Justin can make</u></em>

Number of scarves Justin can make with 15 balls of yarn can be found out by dividing 15 balls of yarn by 3/5 of a ball of yarn

$\text {number of scarves }=\frac{\text { total yarn he has }}{\text { yarn needed for } 1 \text { scarve }}$

$\text {number of scarves }=\frac{15}{3 / 5}$

$\text {number of scarves }=\frac{15}{3} \times 5=25$

Thus he can make 25 scraves
