Answer:

\huge\boxed{x=7}

Step-by-step explanation:

In order to solve for x, our goal is to isolate it on one side of the equation. We can do this by reversing the equation.

Let's apply the distributive property on the left side:

(3 \cdot x) + (3 \cdot -10) = -9\\\\3x-30=-9

Add 30 to both sides:

3x - 30 + 30 = -9 + 30\\\\3x = 21

Divide both sides by 3:

3x \div 3 = 21 \div 3\\\\x = 7

So x = 7.

Hope this helped!

Rasek [7]

Answer:

0.6604

Step-by-step explanation:

Given that a market  research firm knows from historical data that telephone surveys have a 36% response rate.

Sample size of random sample = 280

We know for samples randomly drawn of large size sample proportion follows a normal distribution with mean= sample proportin and std error

= \sqrt{\frac{pq}{n} }

Substitute p = 0.36 and q = 1-0.36= 0.64

p follows N with mean = 0.36 and std dev = \sqrt{\frac{0.36*0.64}{\sqrt{280} } } \\=0.0287

Using normal distribution values we can find\

P(33.5p.c. < p < 39pc)\\= P(0.335
