Answer:
Example: A four-sided shape has two adjacent sides with lengths of 4 meters. You can find the area of this square by multiplying its base times its height: 4 × 4 = 16 square meters. Example: A square's diagonals are both equal to 10 centimeters.
Answer:
C or D definitely not A or B bc it is too close of a number to 24.75 for 15
Step-by-step explanation:
multiply 675 by 0.25 to find 25% of 675. the answer would be 168.75
hope this helps!
Given:
mean = 64
standard deviation = 6
sample size = 50
Standard error of the sample mean = standard deviation / √sample size
Standard error = 6 / √50 = 6/7.07 = 0.85
Answer: 11.46
Step-by-step explanation:
Formula for calculating the length of an arc is theta/360 ×2Πr. Where;
length of the arc (L) = 9
Theta= 45°
L = theta/360 × 2Πr
9 = 45/360× 2Πr
9 = 1/8 × 2Πr
9 = Πr/4
Πr = 36
r = 36/Π
r = 11.46
Substituting we have,
9 = r × 45°
r = 9/45
