Answer:
15
Step-by-step explanation:
According to the problem statement, ...
BC : XY = 5 : 3 = 25 : 15 . . . . . . . multiply each ratio value by 5
The length of XY is 15.
_____
<em>Comment on the figure</em>
Clearly, the figure is not to scale. Not only is XY not parallel to BC, but AY is not 3/5 of AC.
The answer is 15 questions will be worth 4 points
if you have a total of 35 questions on a test and 20 of them are worth 2 points then you would do simple subtraction.
35-20=15
The mean of sample x is 5.83
The standard deviation is 5.63
<h3>What is standard deviation?</h3>
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
Given:
Frequency: 2 2 4 13 13 1
If x is the pair of sneakers owned of the frequency,
mean = 2+2+4+13+13+1/5
= 35/6
= 5.83
The standard deviation is equal to 5.63.

Answer: B has greater spread than A.
Step-by-step explanation:
Since we have given that
Set A: {38, 12, 23, 48, 55, 16, 18}
Range of A = Highest - Lowest
Range of A = 55 - 12
Range of A = 43
Set B:{44, 13, 24, 12, 56}
Range of B = Highest - Lowest
Range of B = 56 - 12
Range of B = 44
Since Range of B is more than range of A.
Hence, B has greater spread than A.
