Step-by-step explanation:
Given that Megan has 25 phone numbers stored in her cell phone. Abby has some phone numbers stored in her cell phone. Together they have a total of 61 phone numbers stored.
If n= the number of phone numbers Abby has stored in her cell phone
then we have sum of phone numbers both have
Answer:
Step-by-step explanation:
The sample size n ( total pairs )=36
Pairs having the even sum less than 10 area
(1,3), (3,1), (1,5), (5,1),(3,5),(5,3),
(2,4), (4,2), (2,6),(6,2),
(1,1),(3,3),(2,2),(4,4)
The number of ways to get a sum that is an even number less than 10= 14
The chances of getting a second turn when he rolls the number cubes=
Hence, The chances of getting a second turn when he rolls the number cubes=
b. 5
c. 7
d. 9
e. 10
Melinda must removeatleast 5 pairs of socks to ensure that she has a pair of each color.
Option B is the correct answer.
We have,
To ensure that Melinda has a pair of eachcolor, she needs to remove at least one sock from each color until she has one sock remaining from each color.
Since she has 3 pairs of red socks, 2 pairs of black socks, and 5 pairs of white socks, the minimumnumber of pairs she must remove is the maximum of these numbers.
The maximum among 3, 2, and 5 is 5.
Therefore,
Melinda must removeatleast 5 pairs of socks to ensure that she has a pair of each color.

Step-by-step explanation:
To calculate the z-statistic, we must first calculate the standard error.
Standard error is standard deviation divided by the square root of the population. In this case, it is equal to 2.68.
The z-score is defined the distance from the sample to the population mean in units of standard error.
z = (195 – 208)/2.68 = -4.86
