Answer:
first you add all the candies together to get 20 in the bag
2+11+7=20
jelly treat:
now we divide 11 by 20 to get a decimal
11/20= .55
multiply .55 by 100 to change it to a percentage
.55*100=55
first part of answer: He has a 55% chance of getting a jelly treat
mint stick:
divide 2 by 20 to get a decimal
2/20=.1
change .1 to a percent by multiplying by 100
.1*100=10
second part of answer: he has a 10% chance of getting a mint stick

Complete Question
A genetic experiment with peas resulted in one sample of offspring that consisted of 432 green peas and 164 yellow peas. a. Construct a 95% confidence interval to estimate of the percentage of yellow peas. b. It was expected that 25% of the offspring peas would be yellow. Given that the percentage of offspring yellow peas is not 25%, do the results contradict expectations?
Answer:
The 95% confidence interval is 
No, the confidence interval includes 0.25, so the true percentage could easily equal 25%
Step-by-step explanation:
From the question we are told that
The total sample size is 
The number of offspring that is yellow peas is 
The number of offspring that is green peas is 
The sample proportion for offspring that are yellow peas is mathematically evaluated as
Given the the confidence level is 95% then the level of significance is mathematically represented as
The critical value of 
from the normal distribution table is
Generally the margin of error is mathematically evaluated as
=> 
=> 
The 95% confidence interval is mathematically represented as
=>

Answer:
Courtney's walking speed = 3.33mph
Brandi's walking speed = 4.33 mph
Step-by-step explanation:
Let x = Courtney's walking speed
then
(x + 1) = Brandi's walking speed
:
Time = Distance/speed
Brandi walks 6.5 mi time = Courtney walks 5 mi time
6.5/x + 1 = 5/x
Cross multiply
6.5x= 5(x+1)
6.5x= 5x + 5
6.5x - 5x = 5
1.5x = 5
x = 5/1.5
x = 3.33 mph is Courtney's walking speed
Note that:
(x + 1) = Brandi's walking speed
3.33mph + 1 = 4.33mph
Therefore,
Courtney's walking speed = 3.33mph
Brandi's walking speed = 4.33 mph
Answer:
1) 22.4
2) 23.4
3) 24.4
4) 25.4
5) 26.4
Step-by-step explanation:
La suma de 5 números consecutivos es 122 ¿cuáles son esos números?
5 números consecutivos se pueden representar como
1) = x
2) x + 1
3) x + 2
4) x + 3
5) x + 4
Por eso:
x + (x + 1) + (x + 2) + (x + 3) + (x + 4) = 122
x + x + 1 + x + 2 + x + 3 + x + 4 = 122
5x +10 = 122
5x = 122 - 10
5 veces = 112
x = 112/5
x = 22.4
5 números consecutivos se pueden representar como
1) x = 22.4
2) x + 1 = 22.4 + 1 = 23.4
3) x + 2 = 22.4 + 2 = 24.4
4) x + 3 = 22.4 + 3 = 25.4
5) x + 4 = 22.4 + 4 = 26.4
