Answer:
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
Step-by-step explanation:
If you know two points that a line passes through, this page will show you how to find the equation of the line.

Step-by-step explanation:
<u>Scientific notation</u>
where:
- is any positive or negative <u>whole number</u>.
To convert a number into scientific notation, <u>move</u> the decimal point to the <u>left or right</u> until there is <u>one digit</u> to the left of the decimal point.
The number of times you have moved the decimal point is .
- If the decimal point has moved to the <u>left</u>, is positive.
- If the decimal point has moved to the <u>right</u>, is negative.
To convert 500,000,000,000 into scientific notation, move the decimal point <u>11 places to left</u>, so a = 5. As we have moved the decimal point 11 places to the left, the exponent "n" is 11 and is <u>positive</u>.
To convert 0.00000000005 into scientific notation, move the decimal point <u>11 places to the right</u>, so a = 5. As we have moved the decimal point 11 places to the right , the exponent "n" is 11 and is <u>negative</u>.

Answer:
predicted GPA=9.21, residual= 1.36, a correct value of slope would be 0.09
Step-by-step explanation:
y=0.1x -3.49
y: GPA
x: IQ
y=0.1(127)-3.49
y= 9.21
Predicted GPA= 9.21
residual= 9.21- 7.85= 1.36
The equation doesn't model the exact relationship between GPA and IQ.
A better slope value could be
7.85= m(127)-3.49
m=0.09
Answer:
12.9
Step-by-step explanation:
cos 72 = 4/x
x = 4/cos72
x = 12.9
Answer:
b. -0.862
Step-by-step explanation:
The only answer choice with a minus sign is B, which is the correct choice.
When the value of interest is below the mean (2800 is below 3550), the z-score will be negative:
z = (2800 -3550)/870 = -750/870 ≈ -0.86207 ≈ -0.862
_____
As always, z is computed as ...
Z = (X -μ)/σ
