1. You need to make a proportion
2. Your proportion would be 8 over 10 equals X over 15
3. Your equation would be 10x=15(8)
4. 15x8=125
5. 10x=125
6. you would divide 125 by 10
7. thats your answer
Answer:
A) 0.386
B).0.325
Step-by-step explanation:
probability p will not work = 0.15
Q probability w5ill work = 0.85
Number of flashlight = 3
Probabilty of at least one=
1- probability of none
But probability of none= 3C0(p)^0(q)^3
= 1*(0.15)^0(0.85)^3
= 1*1*(0.614)
= 0.614
Probability of at least one=1-0.614
= 0.386
Probability of two flashlight work
= 3C1(0.15)^1(0.85)^2
= 3*(0.15)*(0.7225)
= 0.325
Answer/Step-by-step explanation:
$300 is the normal price the sale is 20% off
You would need to multiply them together because it then gives you how much it is off.
Then then you would subtract it.
That takes D and C off.
A , is adding and we arnt adding we are subtracting.
Therefore you answer is: B
I believe x=25 and y=10.
Step-by-step explanation:
Because we know the angles in a parallelogram add up to 360 degrees, we can add up values and divide to find x and y. 8y and 4x-20 are supplementary, they must equal the same value. Same with 10y and the other corner. By this, we can do 10y times 2 and 8y times 2 to get 16y plus 20y, or 36y. Then, we divide 360 degrees by 36. We get y=10 from this. Plug in 10 to 8y and get 80 as the upper left angle measurement. This means that 4x-20 equals 80. Add 20 to 80 on both sides so it cancels out and you get 100=4x. Simply divide and you will get x=25. To make sure this is right, plug all the numbers in and make sure all of the angles add up to 360. Hope this helps :)
