Answer:
26
Step-by-step explanation:
Given that :
2 out of every 5 people buys vanilla ice cream;
If Total number of ice cream sold in a day = 65 ; how many will be vanilla ;
Probability of purchasing vanilla ; p(vanilla) = 2/5 = 0.4
Hence, expected number who bought vanilla :
p(vanilla) * total number of icecream sold
0.4 * 65 = 26
Hence, about 26 of the 65 icecream sold are vanilla flavor.
Answer: 90 inches and 2.5 yards
Step-by-step explanation:
There are 12 inches in a foot. Since there are 7.5 feet, you will multiply 7.5 by 12 to get 90 inches.
7.5 x 12 = 90
There are 3 feet in a yard. Divide 7.5 by 3 to find the amount of yards.
7.5 / 3 = 2.5
Answer:
A = (12 m)(1.5 m) = 18 m^2
Step-by-step explanation:
The area of this parallelogram is the product of the base (12 m) and the height (1.5 m):
A = (12 m)(1.5 m) = 18 m^2
Answer: g(1-t)=3t^2-t-1
Step-by-step explanation:
g(x)=3(x)^2-5(x)+1
g(1-t)=3(1-t)^2-5(1-t)+1
g(1-t)=3(1-t)(1-t)-5-(-5t)+1
g(1-t)=3(1-t-t+t^2)-5+5t+1
g(1-t)=3(1-2t+t^2)-5+5t+1
g(1-t)=3-6t+3t^2-5+5t+1
g(1-t)=3-5+1-6t+5t+3t^2
g(1-t)=-1-t+3t^2
g(1-t)=3t^2-t-1
