Answer:
480
Step-by-step explanation:
Let h represent the number of high-quality downloads. Then the total download size is ...
4.1h +2.7(1130-h) = 3723
1.4h = 672 . . . . . . . . . . . . . . subtract 2.7·1130 = 3051
h = 480 . . . . . . . divide by 1.4
There were 480 downloads of the high-quality version.
Answer:
approximately 38 inches
Step-by-step explanation:
To find the circumference of a circle, you will use the formula C=2⋅π⋅r ; therefore the circumference C is 2⋅π⋅6≈38 inches
To solve this question, use the Binomial probability formula.
The formula is given by
Where:
n = the number of trials
x = the sample we aim to try
p = the probability of success
In this question:
n = 16
x = 9
p = 0.5
Substituting in the equation:
And the combination formula:
Then:
Answer: The probability is 0.1746.
You know x, so just plug it in for the answers. Like AB = x + 7, so since x is 3, then AB is 3 + 7 = 10
BD is 2x + 3x -1 = 6 + 9 - 1 = 14
CE is 3x - 1+ 2x + 3 = 9-1+6+3= 17
6x would be 6 x ? + 2 x ? = 12 probably 6 x 1 + 2 x 3 = 12 same thing for the second one.
