Answer:
75.398223
Step-by-step explanation:
Circumference Formula: 2πr or dπ ⇒ r=radius and d=diamater
1.) π≈3.14
2.) 24×3.14=75.36
Answer:
0.0475
Step-by-step explanation:
First find the z-score.
z = (x − μ) / σ
z = (125 − 100) / 15
z = 1.67
Use a calculator or chart to find the probability. Using a chart:
P(Z > 1.67) = 1 − P(Z < 1.67)
P(Z > 1.67) = 1 − 0.9525
P(Z > 1.67) = 0.0475
Answer:
x = 15
Step-by-step explanation:
-3x+20+7x=80
Combine like terms
4x+20 = 80
Subtract 20 from each side
4x+20 -20 = 80-20
4x = 60
Divide by 4
4x/4 = 60/4
x = 15
Answer:
y = 10x + 100
Step-by-step explanation:
Given the information:
She earns the same amount per hour as she did in her old job $ 100 sign-on bonus
=> the equation for line p in the form y= mx where:
- x is the number of hour she worked
=> the equation for line q in the form y= mx + 100 ($ 100 sign-on bonus )
From that, we see that the two equations have the same slope or you can use a transformation to map line p onto line q
We can create two points (0, 0) and (2, 20) are on line p
<=> m =
The equation for line p is y = 10x
=>The equation for line q should include the hourly earnings at the
new job plus the sign-on bonus. The equation is y = 10x + 100
Hope it will find you well.
