Answer:
67.75%
Step-by-step explanation:
Given:
Given that:
µ = 76 ; σ = 4.7
P(x < 80.7) - P(x < 71.4)
Obtain the standardized score, Z ; x = 71. 4
Zscore = (x - μ) / σ
P(x < 71.4) = (71.4 - 76) / 4.7
P(x < 71.4) = - 4.6 / 4.7
P(x < 71.4) = - 0.9787
P(z < 0.9787) = 0.16386
x = 80.7
P(x < 80.7) = (80.7 - 76) / 4.7
P(x < 80.7) = 4.7 / 4.7
P(x < 80.7) = 1
P(z < 1) = 0.84134
0.84134 - 0.16386 = 0.67748 = 67.748% = 67.75%
When you calculate 2x-3=2x-5 it’s going to lead as -3=-5, therefore this statement is inaccurate and doesn’t have a value of x, it doesn’t even have a solution.
Y=35x+50 bc you already have to pay 50$ and then you spend 35 a hour and the X represents how many hours.
Find the decimal equivalent of each and then put in order.
Steve 130 5/6= 130.83333
Riley 130 2/3= 130.66666
Nikolas 130.5
Carrie 130 7/12= 130.58333
Jorja 130.25
Now that they each have a decimal equivalent, we can put them in order from greatest to least.
Steve 130 5/6= 130.83333
Riley 130 2/3= 130.66666
Carrie 130 7/12= 130.58333
Nikolas 130.5
Jorja 130.25
ANSWER: A) Steve, Riley, Carrie, Nikolas, Jorja
Hope this helps! :)
Answer:
BD = 16
Step-by-step explanation:
By applying mean proportional theorem in the given right triangles,
AD × CD = BD²
8 × 32 = BD²
BD = √256
BD = 16
Therefore, measure of side BD = 16 units.
