Answer:
3/10
Step-by-step explanation:
To find how much remains, you need to find 1/2 of 3/5 which is 1/2 * 3/5. To multiply the two fractions, multiply the two numerators and multiply the two denominators to get 3/10. Thus, 3/10 of the candy bar remains.
Hope this helps :)
Answer:
- x = 6√2
- x = √3
Step-by-step explanation:
1. You have correctly written the relationship between the side lengths and the length of the hypotenuse for these isosceles right triangles.
For this problem, you simply need to multiply the side length by √2. The length of the hypotenuse is then ...
x = 6√2
___
2. The side length multiplied by √2 is √6. You know
√6 = √(2·3) = (√2)(√3) = (√2) · (side length)
so we know that x = √3.

Step-by-step explanation:
Answer:
Mean = 339 hours
Standard deviation = 54 hours
Step-by-step explanation:
We are given that approximately 2.5% of the bulbs have lives exceeding 445 hours
So,P(x>445) = 0.025
P(x<445) =1- 0.025 =0.975
z value for 0.975 is 1.96
Formula : 
So, 
--A
Now we are given that approximately 16% have lives exceeding 393 hours,
So,P(x>393) = 0.16
P(x<393) =1- 0.16 =0.84
z value for 0.84 is 1
Formula :
So, 
---B
Solve A and B
Substitute the value of 
from B in A
Substitute the value in B
So, mean = 339 hours
Standard deviation = 54 hours
Answer: Choice A) x = 15; y = 17
---------------------
Explanation:
The "7x+7" angle and the "112 degree" angle are congruent. They are vertical angles. So
7x+7 = 112
7x+7-7 = 112-7
7x = 105
7x/7 = 105/7
x = 15
We technically have enough to stop here, but let's keep going to find y
The "4y" angle and the "112 degree" angle are supplementary. They form a single straight line. They add to 180 degrees
So,
4y+112 = 180
4y+112-112 = 180-112
4y = 68
4y/4 = 68/4
y = 17
