Total calories = 56
Amount of calories in plum = 32
Remaining Calories = 56 - 32 = 24
Amount of calories with one strawberry = 4
No. of strawberries he ate = 24/4 = 6 strawberries
I hope it is helpful:D

Step-by-step explanation:
Answer:
Lorenzo's score on exam was 75.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 61
Standard Deviation, σ = 8
We are given that the distribution of test score is a bell shaped distribution that is a normal distribution.
Formula:
z-score = 1.75
We have to find the value of x.
Putting values, we get
Thus, Lorenzo's score on exam was 75.
Answer:
0.9155
Step-by-step explanation:
As, the random variable X the number of accident follows the Poisson distribution so,
P(X=x)=(μ^x)(e^-μ)/x!
μ=average accident=4.1.
The probability that more than one accident occurs per year= P(X>1)=?
P(X>1)=1-P(X≤1)
P(X>1)=1-[P(X=0)+P(X=1)]
P(X=0)=(4.1^0)(e^-4.1)/0!
P(X=0)=0.016573/1
P(X=0)=0.016573
P(X=1)=(4.1^1)(e^-4.1)/1!
P(X=1)=(4.1)0.016573/1
P(X=1)=0.0679481
P(X>1)=1-[0.016573+0.0679481]
P(X>1)=1-0.084521
P(X>1)=0.915479
P(X>1)=0.9155
The probability that more than one accident occurs per year is 91.55%
Answer:
1/4
Step-by-step explanation:
2a/b = 1/2
a/b = 1/4
so, b/a = 4
