Answer:
−p−30
Step-by-step explanation:
Let's simplify step-by-step.
4p−5(p+6)
Distribute:
=4p+(−5)(p)+(−5)(6)
=4p+−5p+−30
Combine Like Terms:
=4p+−5p+−30
=(4p+−5p)+(−30)
=−p+−30
Answer:
=−p−30
Answer:
Step-by-step explanation:
Last week, burton paid $36.80 for 11 1/2 gallons of gas. Converting 11 1/2 gallons of gas to decimal, it becomes 11.5. The rate at which Burton bought one gallon of gas last week would be
36.80/11.5 = $3.2
The cost per gallon of gas increased by 5% between last week and this week. The amount by which it increased would be
5/100 × 3.2 = 0.05 × 3.2 = $0.16
The cost of one gallon of gas for this week would be
3.2 + 0.16 = $3.36
She bought 9 1/4 gallons of gas this week. Converting 9 1/4 gallons of gas to decimal, it becomes 9.25 gallons of gas. The amount that she paid for gas this week would be
9.25 × 3.36 = $31.08
Answer: x^2+2x-8<0
Step-by-step explanation:
A. x^2 - 2x - 8 < 0
(x - 4)(x + 2) < 0
B. x^2 + 2x - 8 < 0
(x + 4)(x - 2) < 0
C. x^2 - 2x - 8 > 0
(x - 4)(x - 2) > 0
D. x^2 + 2x - 8 > 0
(x + 4)(x - 2) > 0
When you test a point in the interval between -4 and 2, for example 0, it is negative.
Coefficient of variation is calculated by dividing the standard deviation by the mean multiplied by 100. Given a data set with mean equal to 60 and variance equal to 9, we can calculate the coefficient of variation by finding the value of the standard deviation which is the square root of the variance. so standard deviation is equal to square root of 9 which is 3. Then, the coefficient of variation is equal to 3/60*100 which is equal to 5%.
