Answer:
Subtract 11 from both sides
Step-by-step explanation:
X has to be alone
Answer:
Subtract 11 from sides
Step-by-step explanation:
You have to get the x by itself first
Using the given formula T = LS
And given the time is 3 minutes (3 x 60 = 180 seconds)and the speed is 4-1/2 inches per second:
180 = L x 4-1/2
Solve for L by dividing both sides by 4-1/2:
L = 180 / 4-1/2
L = 40
The length should be 40 inches.
Answer: There would be 9 possibilities.
Step-by-step explanation:
Given : The number of regions in the spinner = 3
if we spin the spinner twice, then by using fundamental principal of counting , the number of possibilities is given by :-
Therefore, there would be 9 possibilities.
b. What is the standard deviation of the amount spent?
c. If we select a family at random, what is the probability they spend less than $2,000 per year on insurance per year?
d. What is the probability a family spends more than $3,000 per year?
Answer: a. 2100
b. 981.5
c. 0.471
d. 0.235
Step-by-step explanation:
Given: According to the Insurance Institute of America, a family of four spends between $400 and $3,800 per year on all types of insurance.
If the money spent is uniformly distributed between these amounts.
Let A=$400 and B= $3,800
a. The mean amount spent on insurance =
b. The standard deviation of the amount spent=
c. To calculate, the probability they spend less than $2,000 per year on insurance per year ,it means the amount is between 400 and 2000 i.e
Amount=$2000-$400=$1600
Then P(400<insurance amount<2000)
d. Ia a family spends more than $3000 then the amount is between $3000 and $3800, i.e. Amount= $3800-$3000=$800
Now,
P(3000<insurance amount<3800)=
The actual number of jelly beans is 300.
