Answer:
a
Step-by-step explanation:
all you do is divied the top then you take from
Earnings=20% of sales+7.5h+40
coeficinets are 7.5 and 0.2
vraiables are h and s
constant is 40
B. if h=25 and s=30 input,
7.5*25+0.2*300+40=$287.50
C
new equation is 9h+0.2s+40
coefienct woud be 9 and 0.2
variable is h and s
constant is 4
The answer to this problem is x = 52/19 = 2.737... I hope...
Answer:
Step-by-step explanation:
Sample proportion p is the proportion of favourable numbers to total number in the sample
By central limit theorem and also approximation of binomial to normal , we have sample proportion for large number of samples will be normal
with mean = sample proportion
and std deviation = 
Thus we find standard deviation of proportion sample is inversely proportional to the square of the sample size n.
It follows automatically that as sample size increases std deviation decreases.
Here from 80 sample size was made to 200
So std deviation would decrease automatically
Step-by-step explanation:
you put the values in place of the variable names and calculate.
y² + x + y
(-4)² + -3 + -4 = 16 - 3 - 4 = 16 - 7 = 9
