Circumference = 2 x radius x Pi
Circumference = 2 x 15 x 3.14
Circumference = 30 x 3.14
Circumference = 94.2 feet
Answer:
<h2>
y = -6x - 16</h2>
Step-by-step explanation:
The point-slope form of the equation is y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope:
m = -6
(-3, 2) ⇒ x₀ = -3, y₀ = 2
The point-slope form of the equation:
y - 2 = -6(x + 3)
So:
y - 2 = -6x - 18 {add 2 to both sides}
y = -6x - 16 ← the slope-intercept form of the equation
Answer:
z-score = 4.43,
It is a Good day
Step-by-step explanation:
The provided information is:
Mean = $28,286.28
Standard deviation = $1,500
Let x be the sell of department store on Tuesday.
Then, x = $34,924.62
The z-score is define as:
Thus, the Tuesday's z-score is 4.43. So this is usually good day.
