mixer [17]

Answer:

B. 84 in²

Step-by-step explanation:

Split the area into two sections by extending 6 in segment.

We get a rectangle of 5 in x 10 in and a trapezoid.

Rectangle:

A = wl
A = 5*10 = 50 in²

Trapezoid:

A = 1/2(b₁ + b₂)h
A = 1/2((15 - 5) + 7)*(10 - 6) = 1/2*17*4 = 34 in²

Total area:

50 + 34 = 84 in²

jek_recluse [69]

Answer:

The margin of error is given below:

$E=z \times \sqrt{\frac{\hat{p}(1-\hat{p}}{n} }$

Where:

$\hat{p}=\frac{26}{80}=0.325$

$\therefore E = z \times \sqrt{\frac{0.325(1-0.325}{80} }$

$=z \times 0.0523659$

Therefore, the option E = z*6% is correct as it closest to the given answer

How many is? with procedure and testing PLEASE -4x + 13 = 6x - 7

slamgirl [31]

To solve for X you must get x by itself so let's get started
-4x+13=6x-7
subtract 13 from both sides
-4x=6x-20
subtract 6x from both sides
-10x=-20
divide both sides by -10
x=2

to check if this is correct plug in x into original equation
-4 (2)+13=6 (2)-7
-8+13=12-7
5=5
answer x=2 holds true :)
