It would weigh 100 pounds. Can I get Brainliest?
Answer:
the answer is 17 or -11
Step-by-step explanation:
|x-3| - 4 = 10
|x-3| = 14
x-3 = 14 or -14
x = 17 or -11
Answer: C. 541.60 hours
Step-by-step explanation:
Since the lifetime of a 2-volt non-rechargeable battery in constant use has a normal distribution, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = lifetime of the batteries.
µ = mean lifetime
σ = standard deviation
From the information given,
µ = 516 hours
σ = 20 hours
Looking at the normal distribution table, the z score corresponding to ninety percent approximately is 1.28
Therefore,
1.28 = (x - 516)/20
Cross multiplying by 20, it becomes
20 × 1.28 = x - 516
25.6 = x - 516
x = 516 + 25.6
x = 541.6
Therefore, Ninety percent of all batteries have a lifetime less than
541.60 hours
The volumes of the clothing bin and the closet can be calculated by multiplying the dimensions.
V (clothing bin) = 20 in x 18 in x 14 in
= 5040 in³
V (closet) = 60 in x 36 in x 72 in
= 155520 in³
To determine the number of clothing bins that can fit the closet, divide the volume of the closet by the volume of the clothing bin. Doing so will give us an answer of 30.85 or approximately 30 clothing bin can fit in the closet.
Answer:
38,200,000
Step-by-step explanation:
Put the 3 in the 8th spot to the left of the decimal point and fill in the other digits to the right of it.
38,200,000
__
The first spot immediately to the left of the decimal point has a place value of 10^0, so the location with a place value of 10^7 is the 8th spot left of the decimal point. You should be able to get the idea from the attached.
__
If you put your calculator in the appropriate display mode, it should show you the number in this form.
