Maritza remembers her pin because it is the product of two consecutive prime numbers that is between 1000 and 1500. what is her pin?

Martiza’s pin number is between 1000 and 1500

It is the product of two consecutive prime numbers

Prime numbers are the numbers that can only be divided by one or itself.

So, prime numbers are 1, 3, 5, 7,………29, 31,37, 41, …..

If we multiply 29 and 31, 29 x 31 = 899 which is not between 1000 and 1500

Next, 31 x 37 = 1147 this is between 1000 and 1500

Next 37 x 41 = 1517, which is above 1500

So, 1147 is her pin number.

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;

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
