Answer: Y = -2X + 105
Step-by-step explanation: let speed = x and mpg = y
Using linear equation
Y = MX +c
M = dy/dt = (15 - 25)/( 40 - 45) =
-10/5 = -2
When y = 15 , x = 45
15 = -2(45) + c
15 = -90 + c
C = 105
The model linear equation will be
Y = -2X + 105
Answer:
4u - 3c - 6
Step-by-step explanation:
Remove the parentheses and combine like factors.
(6u - 7c - 6) + (-2u + 4c)
6u - 7c - 6 - 2u + 4c
4u - 3c - 6
Answer:
A) all values of x, and all values of y
B) (3a + 4b) (9a² − 12ab + 16b²)
Step-by-step explanation:
(x² + y²)² = (x² − y²)² + (2xy)²
x⁴ + 2x²y² + y⁴ = x⁴ − 2x²y² + y⁴ + 4x²y²
x⁴ + 2x²y² + y⁴ = x⁴ + 2x²y² + y⁴
27a³ + 64b³
(3a)³ + (4b)³
(3a + 4b) (9a² − 12ab + 16b²)
Answer: 81 1/2
to determine the total amount of sugar we need to add
21 1/2 + 30 +30
^add the whole numbers the. add the fractions (21 +30+30) + (1/2)<<<
=81 + 1/2
which is equal to
81 1/2
26.8% of examinees will score between 600 and 700.
This question is based on z score concept.
A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values. Z-score is measured in terms of standard deviations from the mean. If a Z-score is 0, it indicates that the data point's score is identical to the mean score.

where:
μ is the mean
σ is the standard deviation of the population
Given:
μ = 560
σ = 90
For
600≤ X≤700
for x = 700
Z score =x - μ/σ
=(700 - 560)/90
= 1.55556
P-value from Z-Table:
P(560<x<700) = P(x<700) - 0.5 = 0.44009
for x = 600
Z score =x - μ/σ
=(600 - 560)/90
= 0.44444
P-value from Z-Table:
P(560<x<600) = P(x<600) - 0.5 = 0.17164
∴ P(600<x<700) = P(560<x<700) - P(560<x<600)
= 0.44009 - 0.17164
=0.26845
∴26.8% percentage of examinees will score between 600 and 700.
