Answer:

<h2>CORRECT</h2>

Step-by-step explanation:

$\dfrac{63}{8}=\dfrac{56+7}{8}=\dfrac{56}{8}+\dfrac{7}{8}=7+\dfrac{7}{8}\to\dfrac{63}{8}=7+r7$

or use the long division (<em>look at the picture</em>).

For the following system, use the second equation to make a substitution for y in the first equation. 2 x + y = 5 y + 3 = 2 x

Anon25 [30]

2x+y=5
y+3=2x
y+3-3 = 2x-3
y= 2x -3

2x + y =5
2x + 2x -3 = 5

Recall the chapter example which described the fact that the mean IQ in large, diverse populations is 100 and the standard devia

vova2212 [387]

Answer:

The margin of error for the 99% confidence level for this sample is ±2.23.

None of the given figures is close to the answer:

E. None of the above

Step-by-step explanation:

margin of error (ME) around the mean can be calculated using the formula

ME= $\frac{z*s}{\sqrt{N} }$ where

z is the corresponding statistic of the 99% confidence level (2.576)

s is the population IQ standard deviation (15)

N is the sample size (300)

Using these numbers we get:

ME= $\frac{2.576*15}{\sqrt{300} }$ ≈ 2.23

a box of crackers has a volume of 48 cubic inches. what is the volume of a similar box that is smaller by a scale factor of 2/3

earnstyle [38]

For this case what you need to know is that the original volume of the cookie box is:
V = (w) * (l) * (h)
Where,
w: width
l: long
h: height.
We have then:
V = (w) * (l) * (h) = 48 in ^ 3
The volume of a similar box is:
V = (w * (2/3)) * (l * (2/3)) * (h * (2/3))
We rewrite:
V = ((w) * (l) * (h)) * ((2/3) * (2/3) * (2/3))
V = (w) * (l) * (h) * ((2/3) ^ 3)
V = 48 * ((2/3) ^ 3)
V = 14.22222222 in ^ 3
Answer:
the volume of a similar box that is smaller by a scale factor of 2/3 is:
V = 14.22222222 in ^ 3
