Answer:
Congruent figures are the same size and the same shape.
We need an image to find which polygons are congruent. Could you give one and then i'll solve it?
Answer: a0 =$97.5 ; a1 =$87.96 ; a2=$282.48; a3=$1,722.5
; a4=$1,553.96
; a5=$4,990.48
Step-by-step explanation:
Hi, to solve this problem we have to multiply each total by the commission in decimal form (6 / 100= 0.06).
So:
$1625 x 0.06 = $97.5
$1,466 x 0.06 =$87.96
$4,708 x 0.06 =$282.48
And finally, to obtain the total costs we have to add to each total the commission of the total.
$1625 + $97.5 = $1,722.5
$1,466 +$87.96 = $1,553.96
$4,708 +$282.48 = $4,990.48
Feel free to ask for more if it´s necessary or if you did not understand something.
Answer:
50.6 cm
Step-by-step explanation:
We can use similar triangles and proportions to solve. Put the smaller triangle side over the larger triangle side.
x 46.2-14 (This is the length of the short side of the triangle)
--------- = -------------
72.6 46.2
Using cross products
46.2 *x = (46.2-14) *72.6
46.2 *x = (32.2) *72.6
46.2 *x = (32.2) *72.6
46.2x =2337.72
Divide each side by 46.2
46.2/46.2 *x = 2337.72/46.2
x = 50.6
Answer:
Step-by-step explanation:
The formula for determining the confidence interval for the difference of two population means is expressed as
Confidence interval = (x1 - x2) ± z√(s²/n1 + s2²/n2)
Where
x1 = mean sale amount for mail order sales = 82.70
x2 = mean sale amount for internet sales = 66.9
s1 = sample standard deviation for mail order sales = 16.25
s2 = sample standard deviation for internet sales = 20.25
n1 = number of mail order sales = 17
n2 = number of internet sales = 10
For a 99% confidence interval, we would determine the z score from the t distribution table because the number of samples are small
Degree of freedom =
(n1 - 1) + (n2 - 1) = (17 - 1) + (10 - 1) = 25
z = 2.787
Margin of error =
z√(s²/n1 + s2²/n2) = 2.787√(16.25²/17 + 20.25²/10) = 20.956190
Answer:
Subtract 3 and one-fifth from both sides of the equation
Step-by-step explanation:
Well to find n you gotta separate it.
3 1/5 + n = 9
-3 1/5
n = 5.8
<em>Thus,</em>
<em>to seperate it you subtract 3 1/5 from both sides.</em>
