ness of 6 inches.
He will order 10% extra concrete to allow for spillage. The cost of concrete is $85 per cubic yard. How much does Ralph need to spend on

Answer:

$20196

Step-by-step explanation:

12 × 9 × 6 = 648 cubic feet ( volume of slab )

3 feet to a yard

So 648 ÷ 3 = 216

Multiply this by 1.1 to add an extra 10%

237.6 Cubic Yards Needed

$85 × 237.6 = $ 20196

Hope this helps

The quality control team of a company checked 800 digital cameras for defects. The team found that 20 cameras had lens defects,
dmitriy555 [2]

Answer:

0.025

Step-by-step explanation:

-This is a conditional probability problem.

-Let L denote lens defect and C charging defect.

#We first calculate the probability of a camera having a lens defect;

P(lens)=\frac{Lens}{Total}\\\\=\frac{20}{800}\\\\=0.025

#Calculate the probability of a camera having a charging defect:

P(Charging)=\frac{Charging}{Total}\\\\=\frac{25}{800}\\\\=0.03125

The  the probability that a camera has a lens defect given that it has a charging defect is calculated as:

P(L|C)=\frac{P(C)P(L)}{P(C)}\\\\=\frac{0.025\times 0.03125}{0.03125}\\\\=0.025

Hence,  the probability that a camera has a lens defect given that it has a charging defect is 0.025

<span>(1/2)n = 0.015625 
n log 0.5 = log 0.015625 
n = log 0.5 / log 0.015625 
n = 6</span><span>24 days / 6 half-lives = 4.00 days (the length of the half-life)

Which table contains only corresponding x-values and y-values where the value of y is one more than the product of x and 2?
Dmitry [639]

Answer:

Option (C)

Step-by-step explanation:

Value of y is more than the product of x and 2.

Equation representing the given condition will be,

y = 2x + 1

Therefore, by substituting the values of x in the equation we can get the table for the input - output values for the equation,

x        0       1         2        3        4

y         1        3        5        7        9

Therefore, table given in the Option (C) will be the correct option.
