Btw this is 6 th grade math i’m just really dumb

26 A =1690.48 in^2

27 B 10 2/15 hours

Step-by-step explanation:

26.  The area of the mat is given by

A = l*w

where l = 74.8 and w = 22.6

A = 74.8 * 22.6

A =1690.48 in^2

27.  The candle is 11 2/5 inches tall.  It burns  1 1/8 inches per hour

We need to divide

11 2/5 ÷ 1 1/8

Changing to improper fractions

11 2/5 = (5*11+2)/5 = 57/5

1 1/8 = (8*1+1)/8 = 9/8

57/5 ÷9/8

Copy dot flip

57/5 * 8/9

456/45

Change back to a mixed number

45 goes into 456  10 times with 6 left over

10 6/45

10 2/15 hours

can i see the following ?

step-by-step explanation:

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;
