Answer:
The equation of line is
Step-by-step explanation:
Here, the two point line are given as is A(5,2) and B(-1,-6)
The slope of the line AB =
⇒ the slope of AB is m = (4/3)
By POINT SLOPE FORMULA:
The equation of a line with slope m and a point (x0, y0) is given as
(y-y0)= m (x-x0)
⇒ The equation of line with point (5,2) is:
Hence, the equation of line is
Answer:
See below
Step-by-step explanation:
The formula for a z-score is
z = (x - µ)/σ where µ is the mean, and σ is the standard deviation.
We are given z = 2.8, µ = 17, and σ = 4. Plug them and and solve for x, which will be her point total..
2.8 = (x - 17)/4
11.2 = x - 17 (multiply both sides by 4 to get rid of the fraction)
28.2 = x (add 17 to both sides)
Yes, this score seems unusual. A z-score of 2.8 puts her in the higher tier of point scorers for the season. She scored 28.2 points in an entire season and was one of the highest scorers, so not many people are scoring points.
*Statistically, an unusual number is a number that is between 2 and 3 standard deviations above the mean. Sarah's score is
2.8 standard deviations above the mean, so by statistical definition, her score is unusual.
Answer:D)10
Step-by-step explanation: If x=10, you take away 1 for 9, divide it by three, which is three. As you said before, 3=k, so the answer is D or 10
Answer:
x = 30
Step-by-step explanation:
x+2x= 90-------> 3x=90
Divide by 3
x= 30
Hope this helps! Pls mark brainliest if correct:)
Answer:
35% discount.
Step-by-step explanation:
28.60 / 44 = 13/20
13/20 = 65/100 = 65%
28.60 is 65% of 44
100 - 65 = 35
Therefore, the discount is 35%.
