In circle E, AC=4, CG=6, and AH=3, Find HB and EG. If necessary, round to the tenths place.
bezimeni [28]
Using theorem about secant segments we can write,
AB*AH=AG*AC
AC=4,
CG=6
AG=AC+CG=4+6=10
AH=3
AB= AH+HB=AH+x=3+x
(3+x)*3=10*4
9+3x=40
3x=40-9
3x=31
x=31/3≈10.3
HB≈10.3
EG=HB/2 (as radius and diameter)
EG=10.3/2≈5.2

The following gives information about the proportion of a sample that agree with a certain statement. Use StatKey or other techn
marishachu [46]

Answer:

(0.2278, 0.3322)

Step-by-step explanation:

Given that out of 400 people 112 agree and 288 disagree

Proportion of people agreeing = \frac{112}{400} =0.28

q=1-p =0.72\\se = \sqrt{\frac{pq}{n} } =0.03175

For confidence interval 90% we have critical value as

1.645

Margin of error =1.645*SE

=1.645(0.03175)\\= 0.0522

Confidence interval = (0.28-0.0522, 0.28+0.0522)\\= (0.2278, 0.3322)

Leslie owns an aquarium that has a volume of 27 cubic feet. Which
Jlenok [28]

Answer:

The answer would be B, or the second option.

Step-by-step explanation:

To find the volume, you must multiply the length, width, and height of the object. (Length x Width x Height)

<em>l × w × h</em>

Replace each of the following variables with the length of each side. In this case, they are all 3, but remember that it doesn't matter in which order you put them in.

3 × 3 × 3.

Now multiply!

3 × 3 × 3 = 27 cubic feet.

Meaning, the final answer would be B.

Are points Q, R, X, &amp; W non-coplanar? Explain.​
-Dominant- [34]

Answer:

No, they are co-planar.

Step-by-step explanation:

Points Q, R, X, and W are all in the plane QRXW. Planes do not have to be at ninety-degree angles (that is, straight up and down or straight to the left and right). However, the points Q, S, U, and X would not be coplanar as a plane must be a flat surface.
