0.75x + 0.5y = 25.....and she doesn't want any licorice....so x = 0
0.75(0) + 0.5y = 25
0.5y = 25
y = 25/0.5
y = 50....she can get 50 cherry candies
17.99 with 20% off 17.99*(1-20%)=14.392
40/14.392=2.779
Have to bye 3 shirts to make it more than $40.
(3*17.99*(1-20%)-10)*(1+7.5%)=35.66
Need to by 3 shirts to use the coupon. The purchase is $35.66.
Hey there!
The answers are as follows:
7.)
m∠1 = 85
m∠2 = 95
m∠3 = 85
m∠4 = 85
8.)
m∠1 = 60
m∠2 = 120
m∠3 = 60
m∠4 = 120
9.)
they all equal 90
10.) No. Parallel lines do not cross each other, but these, if extended, would cross. You could use a protractor by measuring corresponding angles, and if they aren't equal, they aren't parallel.
Have a terrifcly amazing day!
Answer: 1/44
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have that the <span>data set has SSR=400 and SSE=100
2. Therefore you have </span><span>the coefficient of determination is:
r</span>²=SSR/SSTO
SSTO=SSR+SSE
3. Then, when you substitute the values, you obtain:
SSTO=400+100
SSTO=500
r²=400/500
4. So, you have that the result is:
r²=0.8
Therefore, as you can see, the answer for the exercise shown above is: <span> the coefficient of determination is 0.8</span>
