Afactory adds three red drops and two blue drops of coloring to white paint to make each pint of purple paint. the factory will make 50 gallons of this purple paint. how many drops pf red and blue paint will the factory need in the 50-gallon batch of purple paint

1,200 drops of red paint and 800 drops of blue paint

Step-by-step explanation:

8 pints = 1 gallon

3x8=24 red drops

2x8=16 blue drops

After you do the conversions, you’ll see that there are 24 red drops in 1 gallon, and 16 blue drops in 1 gallon. Now multiply both numbers by 50, to see how many drops are used in 50 gallons.

24x50=1,200

16x50=800

In 50 gallons of purple paint, there are 1,200 drops of red paint and 800 drops of blue paint.

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
