The regression equation given to us is y = 0.5x + 1.3
It is in the form y = mx+b
m = 0.5 is the slope
b = 1.3 is the y intercept
The slope of 0.5 indicates that each time x increases by 1, the value of y will increase by 0.5 (since 0.5 = 0.5/1)
Translate this into the context of the problem and that means "for every extra person attending (x), the prep time increases by roughly 0.5 hours" which is what choice C is saying, well a paraphrase of it anyway.
Answer: Choice C
1/3 * 1/3 * 1/3 = 1/27
the volume of the small cubes is 1/27.
there are 180 of them, so multiply.
180 * 1 180 2
---------- = ------ = 6 ---
27 27 3
Answer:
1/2 and 1/5.
Step-by-step explanation:
Two quarters would be 50/100 or 1/2 simplified.
Two dimes would be 20/100 or 1/5 simplified.
Answer:
422.5
Step-by-step explanation:
Given,
Diameter = 23.2
Radius = 23.2 ÷ 2 = 11.6
So, Area is
= 422.5184
As rounding to nearest tenth we check the hundreth digit i. e.
422.5<u>1</u>84
Since, 1 is smaller than 5 so,
<u>422. 5 (Ans) (Rounded to nearest tenth)</u>
