So I got:
-2.9d + 4.6h - 14
Hope it helps.
Have a nice day hyung/noona!~ ￣▽￣❤️
Slope-intercept form is y=mx+b, so we simply have to solve for y...
3y+5x=-15 subtract 5x from both sides
3y=-5x-15 divide both sides by 3
y=-5x/3-5 or more neatly in my opinion...
y=(-5x-15)/3
Given:
Mean, μ = 196
Std. dev., σ = 22
A sample size of 50 (> 30) is large enough to provide meaningful data.
The random variable is x = 200.
The z-score is
z = (x - μ)/σ = (200 - 196)/22 = 0.1818
From normal distribution tables, obtain
Prob(X < 200) = 0.572 = 57.2%
Answer: 57.2%
Ummm I think 14 I am now sure tho..??
Answer:
Step-by-step explanation:
Use proportions to solve.
Corresponding sides have same ratio.
<u>Question 1</u>
- (6x + 3)/17 = (8x - 1)/21
- 21(6x + 3) = 17(8x - 1)
- 126x + 63 = 136x - 17
- 10x = 80
- x = 8
<u>Question 2</u>
- (x + 8)/21 = 32/28
- x + 8 = 21*8/7
- x + 8 = 24
- x = 24 - 8
- x = 16
