To shape service similar create and solve a proportion to find the value of X then find the measure of the unknown side

cupoosta [38]

Answer:

x = 10

6x - 6 = 54

Step-by-step explanation:

The hypotenuse of both triangles are 63 and 6x - 6; the second longest sides are 49 (greater than 35) and 42 (greater than 30).

So our proportion:

63/(6x-6) = 49/42

Cross multiply

63*42 = 49*(6x-6)

2646 = 294x-294

2940 = 294x

x = 10

Double-check:

63/(6*10 - 6) = 49/42

63/(60 - 6) = 49/42

63/54 = 49/42

7/6 = 7/6

6x - 6 = 6(10) - 6 = 60 - 6 = 54

When Stephan moved from Illinois to Florida, his average monthly electric bill increased from $83 to $102. He is curious to know

kondaur [170]

Answer: The z-scores for Stephan's IL and FL electric bills. are -0.625 and 0.75 respectively.

Step-by-step explanation:

Given: Average monthly electric bill in Illinois = $83

Average monthly electric bill in Florida = $102

Formula of z : $z=\dfrac{X-mean}{standard\ deviaton}$

In Illinois, the mean monthly electric bill is $85, with a standard deviation of $3.20.

$z=\dfrac{83-85}{3.20}= -0.625$

In Florida, the mean monthly electric bill is $105, with a standard deviation of $4.00.

$z=\dfrac{105-102}{4}=\dfrac{3}{4}=0.75$

Hence, the z-scores for Stephan's IL and FL electric bills. are -0.625 and 0.75 respectively.
