Answer:
0.538
Step-by-step explanation:
7 divided by 12 = 0.538
Answer:
12.16
Step-by-step explanation:
From your question, we have the following information
Mean = u = 20
Standard deviation sd = 4
P(X>Xo) = 0.975
1-0.975 = 0.025
P(z<Xo-20/4) = 0.025
Xo-20/4 = -1.96
We cross multiply
Xo - 20 = -1.96 x 4
Xo - 20 = -7.84
Xo = -7.84+30
Xo = 12.16
12.16 is the value of Xo and therefore the answer to this question.
Thank you!
Answer:
x=0.8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4x+8=5x+7.2
Step 2: Subtract 5x from both sides.
4x+8−5x=5x+7.2−5x
−x+8=7.2
Step 3: Subtract 8 from both sides.
−x+8−8=7.2−8
−x=−0.8
Πd = c/π
Cross multiply
π²d = c
Divide both side by d
π²d/d = c/d
π² = c/d
Take the square root of both side
Result: π = √(c/d)
