Answer: D) 0.78
Step-by-step explanation:
Add all the given probabilities to find the answer:
45/100 + 18/100 + 15/100 = 78/100 = 78% or 0.78
First, set a variable.
Let x = the number of songs bought.
Each song costs 2 dollars. So, we have our first term: 2x.
And there is a fee of 5 dollars for using the website.
2x + 5
And she can't spend any more than 40 dollars. Which means she can spend 40 and under.
So, 2x + 5 ≤ 40 is the answer.

Answer:
27 cm³
Step-by-step explanation:
The surface area of a cube is ...
SA = 6s²
Then the edge length is ...
54 cm² = 6s² . . . . . please note that cm³ is not the appropriate unit for area
9 cm² = s² . . . . . .divide by 6
3 cm = s . . . . . . . take the square root
The volume of a cube is ...
V = s³
V = (3 cm)³ = 27 cm³
The volume of the cube is 27 cm³.
What is the interquartile range of the data? 24, 25, 27, 36, 37, 42, 42, 43, 49, 49, 50, 53, 59, 61, 65 41 7 17 10

<span>The interquartile range is the difference between the third quartile and the first quartile. First, find the median so you can separate the data in half. The median is the middle number. Arrange the numbers from least to greatest and find the number in the middle.

Find the medians of these two halves. These will be Quartile 1 and Quartile 3.
Quartile 1 is 36
Quartile 3 is 53
Answer:
35/4
Step-by-step explanation:
Because these are corresponding angles,
4x + 10 = 8x - 25
4x = 35
x = 35/4
