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:
(x, y) = (-3 5/8, 1 5/16)
Step-by-step explanation:
Add y+14 to the second equation to get ...
3.5x +14 = y
Substitute this for y in the first equation:
2.5x -3(3.5x +14) = -13
2.5x -10.5x -42 = -13
-8x = 29
x = -29/8 = -3 5/8
Using this in the formula for y, we get ...
3.5(-29/8) +14 = y
-203/16 +14 = y = 21/16 = 1 5/16
Answer: x = 19/189
Step-by-step explanation:
Add the same term to both sides of the equation
Simplify
Multiply all terms by the same value to eliminate fraction denominators
Simplify
Divide both sides of the equation by the same term
Simplify
0.84 is 10 times as much as 0.084
Answer:
x=17
Step-by-step explanation:
7x+10+3×=180
10x+10=180
-10. -10
10x/10=170/10
x=17
