Answer:
<h2>A) Height is the missing measurment.</h2><h2 /><h2> B) 1,400= 20 × 14 × H</h2><h2 /><h2>C) 1400 ÷ H = 280</h2>
Step-by-step explanation:
A) Length × Width × Height
B) V is 1,400
L is 20
W is 14
H is unknown so use a variable
C) 20 × 14= 280.
Answer:
The third one.
Explanation:
A dilation is a shrink or a stretch of a figure.
In a dilation, all sides either increase or decrease by the same scale factor. Additionally, in a dilation the angle measures of the figure do not change.
In the first figure, we can see that the base angles of the pre-image are slightly different than those of the image. This is not a dilation.
In the second figure, the angles are noticeably different; again, not a dilation.
In the fourth figure, much like the second figure, the angles are noticeably different. This is not a dilation.
In the third figure, however, we can see that the slanted sides of the larger figure go through three boxes; they are three units long. Additionally we can see that the slanted sides of the smaller figure go through 1 side; this is a dilation b a factor of 3.
The base sides of the third figure, in the larger shape, are 6 units long; in the smaller figure, they are 2 units long. This is a dilation by a factor of 3.
Look at it this way:
-- Since the two groups have the ratio of 4 to 7, then the first group has 4 parts
and the other group has 7 parts.
-- If the first group has 4 parts and the other group has 7 parts, then they have
11 parts all together.
-- Those 11 parts are all parts of 33. There must be ( 33 / 11 ) = 3 items in each part.
Now you can go back to the groups . . .
-- The first group has 4 parts.
With 3 items in each part, that's (4 x 3) = 12 items.
-- The other group has 7 parts.
With 3 items in each part, that's (7 x 3) = 21 items.
Answer:
(0.2278, 0.3322)
Step-by-step explanation:
Given that out of 400 people 112 agree and 288 disagree
Proportion of people agreeing = 
For confidence interval 90% we have critical value as
1.645
Margin of error =1.645*SE
=
Confidence interval 
The answer is:
(x-5 - sq root 29) (x-5 + sq root 29)
