Answer:
B
Step-by-step explanation:
a^2 + b^2 = C^2
solve for b
b^2 = c^2 - a^2
square root on both sides of the equation and you get option b as your answer
Answer:
x = 3
y = 15
Step-by-step explanation:
If △XPS ≅△DNF, their corresponding sides would be congruent. This implies that:
XP ≅ DN
PS ≅ NF
XS ≅ DF
Given that:
XP = 4y - 3
DN = 57
NF = 51
XS = 17x + 3
DF = 54
Therefore:
XP = DN
4y - 3 = 57 (Substitution)
Add 3 to both sides
4y = 57 + 3
4y = 60
Divide both sides by 4
y = 60/4
y = 15
Also,
XS = DF
17x + 3 = 54 (substitution)
Subtract 3 from each side
17x = 54 - 3
17x = 51
Divide both sides by 17
x = 51/17
x = 3
The answer is y=(1/2)x -5
You are given the slope and a core donate pair so you plug them in to the equation. 2=x. -4=y. And (1/2)= m
Then work out like a one step equation
Answer:
The average age of pilots has a lower coefficient of variation, so it is the most consistent data set.
Step-by-step explanation:
The coefficient of variation is used to measure consistency of a data set. It is the standard deviation divided by the mean. The higher the coefficient of variation, the more variable, that is, the least consistent the data set is.
The average number of newspapers for sale in an airport stand is 15. SD is 6.
The consistency is:
The average age of the pilots is 36 and SD is 4.
The consistency is:
The average age of pilots has a lower coefficient of variation, so it is the most consistent data set.
Answer: Correct
Step-by-step explanation:
The conclusion is valid. Since 
and 
, we know that ABCD is a parallelogram because it has two pairs of parallel sides. Also, since 
, we know that ABCD is a parallelogram with a pair of consecutive congruent sides, making it a rhombus.
