Answer: 7
Step-by-step explanation:
Since we are given the information that a group of friends had 28 driveways to shovel and that one of them shoveled 1/4 of the driveways.
The number of driveways that he shovel will be:
= 1/4 × 28
= 7
Therefore, he shovel 7 driveways.
Answer:
1
Step-by-step explanation:
Any positive integer to power of 0 will ALWAYS be 1.
For this you need to use the reverse cosine function
Cos^-1 (.25)
75.6
Option B. 12/ 125 is the answer.
Explanation
Total umber of sour ball candies = 50
Number of lemon candies = 12
Hence the probability to get a lemon candy is = 12/50
Number of cherry sour balls = 20
So, the probability to get a cherry sour ball = 20/50
So, to get the joint probability for a random selection to either get a lemon or cherry candy, we will multiply both the probabilities.

= 
Answer: Option 'e' is correct.
Step-by-step explanation:
Since we know that
Discrete data are those data which is countable and it is expressed in exact numerical form.
Continuous data are those data which is lie within the interval and it varies so it does not expressed in exact numerical form.
Here, the number of iphones sold today at an Apple store is countable and it can be expressed in exact numbers.
So, it is considered as discrete.
Hence, Option 'e' is correct.
