What are the most estimates to the sqrt of 14

9 < 14 < 16

sqrt (9) < sqrt (14) < sqrt (16)

3< sqrt(14) <4

for 67

64< 67 < 81

sqrt(64)<sqrt(67) <sqrt(81)

8<sqrt(67) <9

Choice C

Step-by-step explanation:

To estimate the square root of 14, we will look for numbers that have squared values nearest to the number 14.

We can think of 9 (square of 3) and 16 (square of 4) as the two nearest possible values to 14 so we can write it as:

Similarly, tp estimate the square root of 67, we can think of 64 (square of 8) and 81 (square of 9) to be the nearest values to 67.

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;
