If a=2b=3c=6, find the value of
a+2b-4c how to calculate this one

4

Step-by-step explanation:

Based on the equation you are given, calculate the values of a, b, and c. Then substitute each value for the corresponding variable and use the correct order of operations.

a = 2b = 3c = 6

a = 6

2b = 6, so b = 3

3c = 6, so c = 2

a + 2b - 4c =

= 6 + 2(3) - 4(2)

= 6 + 6 - 8

= 12 - 8

= 4

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;

sorry i just need to anwers this to get points
