Answer:
(y-5t)/5=x
Step-by-step explanation:
y=5t+5x
factorize
y=5(t+x)
divide both sides by 5
y/5=5(t+x)/5
y/5=t+x
make x to stand alone
y/5-t=x
take lcm of 5 and 1
y/5-5t/5
y-5t/5=x
Answer:
The constant term in the polynomial is 140 and it represents the revenue when the price is not increased.
Step-by-step explanation:
To find: What is the constant term in the polynomial expression, and what does it represent?
The given expression is
.
To find the constant term we can simply put x=0 in the given equation where x represents the number of $1 increase in price.
=
=
The constant term is 140 and it represents the revenue when the cost of a hot dog is $2.
Hence, the constant term in the polynomial is 140 and it represents the revenue when the price is not increased.
Answer:
B
Step-by-step explanation:
w=width
l=w+3
(w+4)=width+walkway(both sides)
(w+7)=length+walkway(both sides)
Answer:
31.92%
Step-by-step explanation:
We are given;
Population mean; μ = $3.12
Sample mean; x¯ = $3.16
Sample size; n = 10
Standard deviation; σ = $0.27
Z-score formula is; z = (x¯ - μ)/(σ/√n)
z = (3.16 - 3.12)/(0.27/√10)
z = 0.04/(0.08538)
z ≈ 0.47
Now, the percent of other sample means, based on 10 gas stations, that would be greater than the one observed is;
P(x¯ > 3.12) = 1 - P(z < 0.47)
From z-table attached P(z < 0.47) = 0.68082
Thus;
P(z > 0.47) = 1 - 0.68082
P(z > 0.47) ≈ 0.3192
This expressed in percentage is 31.92%
