Answer:

The value of the test statistic is z= -14.53

Step-by-step explanation:

Pcap= 0.3 ,p=0.5 ,q= 1-0.5= 0.5, n=1320

Z= (pcap- p) / √(p×q)/n

Z=( 0.3- 0.5) / √ (0.5 × 0.5)/1320

Z= -0.2/(√0.0001894)

Z= -14.53

All you have to do is divide 4 from a and 52.

4a<52

/4 /4

a<13

a<208 √

a<56 √

a<48 √

a<13 X

So the odd one out is a<13

<h3>Answer:</h3>

$10x+35$

<h3>Solution:</h3>

Use the distributive property to simplify.
The distributive property states the following:
x(y+z)=xy+xz (x times y plus x times z)
Now, simplify:
$5(2x+7)$
$10x+35$
I multiplied 5 times 2x and 5 times 35.
Is $10x+35$ the final answer? Yes, we cannot simplify it anymore, because 10x and 35 are not like terms.
