So y=mx+b
m=slope
y=-3x+b
subsitutue 1 for x and 4 for y
4=-3(1)+b
4=-3+b
add 3 to both sides
7=b
the equaiton is y=-3x+7
Step-by-step explanation:
-2x+3=x+12
combin like terms
-2x-x=12-3
-3x=9
x=9/-3
x=-3
The explanation is:
The definition of "secant of (x)" is: 1 / (sine of x) .
Answer:
The value of an appropriate test statistic for the car dealer to use is -4.
Step-by-step explanation:
The null hypothesis is:
The alternate hypotesis is:
The test statistic is:
In which X is the sample mean, 
is the value tested at the null hypothesis, 
is the standard deviation and n is the size of the sample.
In this problem:
Then
The value of an appropriate test statistic for the car dealer to use is -4.
Answer: Obtuse
Step-by-step explanation:
Acute angles are Between 0 and 90 degrees
Right angles are 90 degrees
Obtuse angles are 90-180 degrees
And straight angles are 180 degrees
Note: Between mean like Ex. between 1-10 it would be 2, 3, 4,... 8, 9
