Answer:

The greatest number of 15 inch pieces he can get is 5

Step-by-step explanation:

Given

Length of boards = 7 foot.

Size of pieces needed = 15 inches

We want to calculate the greatest number of 15 inches pieces he can get...

First, the length of the board has to be converted from foot to inches

If 1 inch = 12 foot, we can get the equivalent of 7 foot by multiplying both sides by 7.

So, 1 foot = 12 inches becomes

7 * 1 foot = 7 * 12 inches

7 foot = 84 inches

To calculate the greatest number of 15 inch pieces he can get, we have to divide the length of the board by 15.

Number of pieces = 7 foot / 15 inches

Number of pieces = 84 inches / 15 inches

Number of pieces = 5.6

By rounding down 5.6 , we get the greatest number of 15 inch pieces he can get.

Hence, the greatest number of 15 inch pieces he can get is 5

the answer would be 33. so the first thing you want to do is turn 7 feet into inches. if 12 inches is equal to 1 foot then 7 feet are equal to 84 inches. then add another 84  inches which will equal 168. the you would want to divide 168/15 which gives you 33.6. this mean that 33 (separate numbers) 15 inches of board from two boards.

hope I was able to help and that my explanation made sense. : )

Answer:

a) 14960 bottles

b) 502 bottles

Step-by-step explanation:

Given that:

Mean (μ) = 24 ounces, standard deviation (σ) = 0.14 ounces

a) From empirical rule (68−95−99.7%) , 68% of the population fall within 1 standard deviation of the mean (μ ± 1σ).

Therefore 68% fall within 0.14 ounces of the mean

the number of bottle =  22,000*68% = 14960 bottles

b) To solve this we are going to use the z score equation given as:

z=\frac{x-\mu}{\sigma} where x is the raw score = 23.72

z=\frac{x-\mu}{\sigma}=\frac{23.72-24}{0.14} =-2

From the normal probability distribution table: P(X < 23.72) = P (Z < -2) = 0.0228

The number of rejected bottles = 22000 × 0.0228 = 502 bottles

At the parents evening the ratio of mums to dads was 3:2. Out of 500 appointments how many were with mums?
guajiro [1.7K]

Answer:

300

Step-by-step explanation:

Sum the parts of the ratio : 3 + 2 = 5 parts

Divide the number of appointments by 5 to find the value of one part of the ratio, that is

\frac{500}{5} = 100 ← value of 1 part of the ratio

The mums consisted of 3 parts, hence

3 × 100 = 300 ← appointments with mums
