Answer:
A. -9n + 20
Step-by-step explanation:
First, distribute -5 to all terms within the parenthesis:
-5(2n - 4) + n
(-5 * 2n) + (-5 * -4) + n
-10n + 20 + n
Simplify. Combine like terms:
(-10n + n) + 20
(-9n) + 20
A. -9n + 20 is your answer.

Answer:
B. 0.73
Step-by-step explanation:
Add all numers so the first is 2/10 = 0.2
then 35/100 = 0.35
and then 16/100 = 0.16
finally 2/100 = 0.02
Now add all decimals which is equal to 73/100 = 0.73 and that's your answer.

Answer:
∠6=78° ∠7=102° ∠14=78°
Step-by-step explanation:
Angles 6 and 7 are supplementary angles so ∠a+∠b=180°
in this case it would be 102°+x=180° and you subtract 102° from 180° getting 78°
∠7 is the vertical angles postulate stating that any angles vertical to each other are eaqual
Answer:
Hence the best estimate is population with correct option is 74% and
the value for x=148
Step-by-step explanation:
Given:
A sample of 200
Of which 148 prefer brand new coffee
To Find:
Which statement is true?
Solution:
n=200
x=148
remaining 52 prefer old ones .
So estimate population proportion,
p=x/n
p=148/200
p=0.74
p=74 %
Now, when x=52
p=x/n,
p=52/200
p=0.26
p=26%
There is no option for 52 and 24 %
Hence x=148 and p=74%.
