Answer:

m∠1 = 71°

Step-by-step explanation:

Angle 1 and 2 are complementary, meaning the measures of the two angles add up to 90°.

Set the measures of the two angles equal to 90°

(4x+3)+(x+2)=90\\

Combine like terms

5x+5=90

Solve for x

x=17

Plug the value of 'x' back into the given equation for the measure of angle 1

m

m∠1 = 71°

Answer:

Step-by-step explanation:

Complimentary angles are two acute angles whose sum is 90 degrees.

Angle 1 = 4x + 3

Angle 2 = x + 2

Since angle 1 and angle 2 are complimentary angles, it means that

4x + 3 + x + 2 = 90

4x + x + 5 = 90

Subtracting 5 from the left hand side and the right hand side of the equation, it becomes

5x + 5 - 5 = 90 - 5

5x = 85

Dividing the left hand side and the right hand side of the equation by 5, it becomes

5x/5 = 85/5

x = 17

The measure of angle 1 would be

4 × 17 + 3 = 68 + 3 = 71 degrees

A random sample of adults were asked whether they prefer reading an e-book over a printed book. The survey resulted in a sample
djyliett [7]

Answer: (0.10\ ,\ 0.18)

Step-by-step explanation:

According to the empirical rule, the 95% confidence interval for the true population proportion is given by :-

(p'-2\sigma_{p'}\ ,\ p'+2\sigma_{p'})

Given : . The survey resulted in a sample proportion of p′=0.14, with a sampling standard deviation of σp′=0.02, who preferred reading an e-book.

Then, the 95% confidence interval for the true proportion of adults who prefer e-books will be :-

(0.14-2(0.02)\ ,\ 0.14+2(0.02))\\\\=(0.14-0.04\ ,\ 0.14+0.04)\\\\=(0.10\ ,\ 0.18)

Hence, the 95% confidence interval for the true proportion of adults who prefer e-books= (0.10\ ,\ 0.18)

Assuming you meant is - \frac{3}{5} x+ \frac{1}{5} \ \textgreater \  720

The answer would be :
- \frac{3}{5} x\ \textgreater \ 719.8

x \ \textless \  \frac{719.8}{ \frac{-3}{5} }
x\ \textless \  719.8 *( \frac{-5}{3} )
x\ \textless \  \frac{-3599}{3}

Hope this helps !
