Answer:
you can use a graph like a bar graph or a pie chart. or a table that has two parts like what is linked. make sure for the graph to have a key
Step-by-step explanation:
The probablity that the sample's mean length is greate than 6.3 inches is0.8446.
Given mean of 6.5 inches,standard deviation of 0.5 inches and sample size of 46.
We have to calculate the probability that the sample's mean length is greater than 6.3 inches is 0.8446.
Probability is the likeliness of happening an event. It lies between 0 and 1.
Probability is the number of items divided by the total number of items.
We have to use z statistic in this question because the sample size is greater than 30.
μ=6.5
σ=0.5
n=46
z=X-μ/σ
where μ is mean and
σ is standard deviation.
First we have to find the p value from 6.3 to 6.5 and then we have to add 0.5 to it to find the required probability.
z=6.3-6.5/0.5
=-0.2/0.5
=-0.4
p value from z table is 0.3446
Probability that the mean length is greater than 6.3inches is 0.3446+0.5=0.8446.
Hence the probability that the mean length is greater than 6.3 inches is 0.8446.

Answer:
$120
Step-by-step explanation:
Simple interest = principal (P) × rate (R) × time (T) / 100
Principal = $800
Rate = 3%
Time = 5 years
Simple interest = principal (P) × rate (R) × time (T) / 100
= (800 × 3 × 5) / 100
= 12,000 / 100
= 120
Simple interest = $120
The total amount of interest Mr. Espinoza will have at the end of 5 years is $120

Answer:
x = 5
Step-by-step explanation:
Assuming the given expressions are supposed to be angle measures, their sum must be 180°.
(14x +5) +(5 +20x) = 180
34x = 170 . . . . . . . . . . . . . . subtract 10, collect terms
x = 5 . . . . . . . . . divide by 34
