Answer:
Step-by-step explanation:
SV = RV
2x+2 = 10
x = 4
r² = RV² + VZ² = 10²+7.5² = 156.25
UZ = √[r²- (QR/2)²] = √[156.25 - 10²] = √56.25 = 7.5
The true comparison is the typical value is greater in set A. The spread is greater in set B.
<h3>What is the true comparison?</h3>
Spread is used to measure the variability of a data set. Range can be used to measure spread. Range is the difference between the largest number and the smallest number in the dataset.
- Spread of set A = 7 - 5 = 2
- Spread of set B = 8 - 1 = 7
The median can be used to measure the typical value of the dataset. Median is the number at the center of the data set.
- Median of set A = 6
- Median of set B = 4

Answer:
Her pin must be 1147
Step-by-step explanation:
A little trick I have up my sleeve when I have these kind of questions is that I find the square root of each number, then find what is prime.

Since the only prime numbers in the range of 31 and 38 is 31 and 37.
We can then multiply 31 by 37 to get 1147.
