Answer:
y=mx+b broken down is in the step by step explanation.
Step-by-step explanation:
y=mx+b is the y intercept formula.it is mostly used for slopes.
y is usually equal to the total,or final answer.it is the start.
m is equal to the slope.in the formula.it can also be used as the rise over run,which means the top number is the amount of units you go up for rise,and run is the bottom number which is the amount of units you move to the right.if it is negative,you move the opposite ways.if it is a single number,the bottom number can be 1.
x is equal to the number you multiply m,or the slope by.
b is equal to where you start on the vertical line in the graph.a way to remember it is horizontal is like a horizon,it’s flat.
This is your answer, hope this helps :D !
Place the right angle at the origin. Short leg on x-axis.
The forth corner of the square is the point on the hypotenuse where the line y = x intersects. (Draw a diagram!)
In this case the hypotenuse is y = -4x/3 + 8
x = -4x/3 + 8
7x/3 = 8
7x = 24
x = 3.428571429
Answer:
7 1/2 miles
Step-by-step explanation:
The distance to the airport is 10 miles
The distance to the lake is 3/4 the distance to the airport
d =3/4 *10
d =30/4 = 7 2/4 = 7 1/2 miles
Answer:
(29.14 ; 30.06)
Step-by-step explanation:
Given that'
Sample size (n) = 57
Mean (m) = 29.6
Population standard deviation (σ) = 2.7
Confidence interval = 80%
= (1 - 0.8) / 2 = 0.1
Mean ± z * σ/√n
Using the Z probability calculator : Z0. 1 = 1.28
Hence,
29.6 ± 1.28 * (2.7 / √57)
29.6 - (1.28 * 0.3576237) ; 29.6 + (1.28 * 0.3576237)
29.142241664 ; 30.057758336
(29.14 ; 30.06)
