Answer:
(-3, 3)
explanation:
- original coordinate of C: (3, 5)
if reflected over y axis, use the formula: (x,y) → (-x, y)
If translated vertically, there will be change in y axis
- then vertically -2 units:
(-3, 5-2) → (-3, 3)
Answer:
Hence, if the tire wears in less than equal to 27410.4 miles, then the mechanic will replace approximately 10% of the tires.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 31,000
Standard Deviation, σ = 2,800
We are given that the distribution of life expectancy is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.10
P(X<x) = 0.10
Calculation the value from standard normal z table, we have,
Hence, if the tire wears in less than equal to 27410.4 miles, then the mechanic will replace approximately 10% of the tires.
A1 = first term
a1 = 15
---------------------------------------------
d = common difference
d = (second term) - (first term)
d = a2 - a1
d = 9-12
d = -3
The negative common difference indicates that the terms are decreasing
Each time we subtract 3, or add -3, to get the next term.
----------------------------------------------
nth term of arithmetic sequence
an = a1 + d(n-1)
an = 15 + (-3)(n-1)
an = 15- 3n + 3
an = 18 - 3n
Answer is choice D
Answer:
-3⁵
Step-by-step explanation:
3⁶ / -3 = -3⁶ * -3⁻¹ = -3⁶⁻¹ = -3⁵
