The two key parts of regression equation involve the______ and the y'________ a. slope; axis
b. asymptote; axis
c. asymptote; intercept
d. slope; intercept

Answers

Answer 1
Answer:

Answer:

d. slope; intercept

Step-by-step explanation:

A regression equation is represented in the form :

y = mx + c (linear regression)

Where y = predicted variable

m = slope of regression line

x = independent variable

c = intercept (where the regression line crosses the y axis).

For a multiple regression equation where there are more than one independent, then we have multiple slopes

y = c + m1x1 + m2x2 +...mnxn

Hence, the slope. And intercept are the two key part of a regression equation which enables us to make prediction and correlation about the dependent and independent variables.

Find the absolute maximum and minimum values of the function over the indicated​ interval, and indicate the​ x-values at which they occur. f (x )equals8 x minus 5 ​(A) ​[0​,4​] ​ (B) [negative 4 comma 3 ]

Answers

Answer:

a. Maximum= 27, minimum= -5

b. Maximum= 19, minimum=-37

Step-by-step explanation:

We have the function f(x)=8x-5. Since the function correspond to a line, then the maximum and minimum values of the function over an interval are in the endpoints of the interval.

Observe that if the line has negative slope then the minimum value is in the right endpoint. If the line has positive slope the minimum value is in the left endpoint of the interval.

The function f(x) has slope m=8. Then

a. the minimum value of f(x) in the interval [0,4] is reach when x=0, and the minimum is f(0)=8*0-5=-5 and the maximum is f(4)=8(4)-5=32-5=27

b. the minimum value of f(x) in the interval [-4,,3] is reach when x=-4, and the minimum is f(-4)=8(-4)-5=-32-5=-37 and the maximum is f(3)=8(3)-5=24-5=19

80 plus what equals 44??

Answers

Answer:

-36

Step-by-step explanation:

80 + (-36) = 44

The negative in the 36 allows it to be subtracted from 80

Answer:

80 + -36

Step-by-step explanation:

80 - 44 = 36

80 + -36 = 44

The ratio of the measure of the angels of a triangle is 6:10:2 find the measure of the smallest angle

Answers

Answer:

20°

Step-by-step explanation:

6x+10x+2x=180 (Triangles have three angles that add up to 180)

18x=180 (Combine like terms)

x=10 (Dividing by 18 to find x)

2(10)=20 (Looking for smallest angle which is 2)

The mean breaking strength of a ceramic insulator must be at least 10 psi. The process by which this insulator is manufactured must show equivalence to this standard. If the process can manufacture insulators with a mean breaking strength of at least 9.5 psi, it will be considered equivalent to the standard. A random sample of 50 insulators is available, and the sample mean and standard deviation of breaking strength are 9.32 psi and 0.21 psi, respectively. a. State the appropriate hypotheses that must be tested to demonstrate equivalence.

Answers

Answer:

H0: u ≥ 9.5

Ha:  u < 9.5

Step-by-step explanation:

The null hypothesis and the alternate hypothesis are reverse of each other.

The claim is either set as the null or alternate hypothesis

The null hypothesis  is : H0: u ≥ 9.5  the mean breaking strength of a ceramic insulator is at least 9.5 which is considered equivalent to the standard.

The alternate hypothesis is: Ha:  u < 9.5 the mean breaking strength of a ceramic insulator is less than 9.5 which is  not considered equivalent to the standard.

The Richter Scale gives a mathematical model for the magnitude of an earthquake in terms of the ratio of the amplitude of an earthquake wave (also known as the intensity of an earthquake) to the amplitude of the smallest detectable wave. If we denote the magnitude of the earthquake by R, the intensity (also known as the amplitude of the earthquake wave) of the earthquake by A, and the amplitude of the smallest detectable wave by S, then we can model these values by the formula R=log(AS) In 1906, San Francisco felt the impact of an earthquake with a magnitude of 7.8. Many pundits claim that the worst is yet to come, with an earthquake 748,180 times as intense as the 1906 earthquake ready to hit San Francisco. If the pundits ability to predict such earthquakes were correct, what would be the magnitude of their claimed earthquake? Round your answer to the nearest tenth.
