Answer:
The scores above 1.08 standard deviation from the mean are publicly recognized.
Step-by-step explanation:
We are given the following information in the question:
Mean = μ
Standard Deviation = σ
We are given that the distribution of score is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.14
Calculation the value from standard normal z table, we have,
Thus, scores above 1.08 standard deviation from the mean are publicly recognized.
Answer:
Step-by-step explanation:
y = -2/3 x multiply both sides the first equation by 6
6y = -4x Add 4x to both sides.
6y + 4x = 0
<u>-9y +4x = - 40 </u> Subtract the bottom equation
15y = - 40 Divide by 15
y = -40/15
y = - 2.7
======================
6y = -4x
6*(-2.67) = -4x
-16 = - 4x
x = - 16/-4
x = 4
8500 you make two fractions set equal to eachother.. 6290/x (x is the missing number) and 74/100 (the percentage) you cross multiply the 6290 and 100 which is 629000 and divide it by the 74 which is 8500 which should be your answer
Step-by-step explanation:
y-4 = 5x -40
-5x + y = -36
y = -3/5x + 2
y-2 = -3/5x
5y - 10 = -3x
3x + 5y = 10
