A perfect square is the square of an integer. Of the integers from 2 through 99, how many have at least one perfect square facto
N76 [4]

Answer:

Six numbers have perfect square factors

Step-by-step explanation:

The numbers with perfect square factors are those numbers that have perfect squares as one of the numbers that can divide them.

They include:

4 = 2 * 2

16 = 4 * 4

36 = 6 * 6

49 = 7 * 7

64 = 8 * 8

81     = 9* 9

These numbers above have perfect square factors because they are formed from integers that multiply themselves.

A quality control expert at LIFE batteries wants to test their new batteries. The design engineer claims they have a variance of
emmainna [20.7K]

Answer:

z = \frac{981.7 -997}{\frac{62}{\sqrt{73}}}= -2.108

And we can use the normal standard distribution table or excel and with the complement ruler we got:

P(z>-2.108) =1- P(z

Step-by-step explanation:

We know the following info given:

\mu = 997 represent the true mean

\sigma = \sqrt{3844}= 62 represent the population deviation

n = 73 represent the sample size selected

Since the sample size is large enough (n>30) we can use the central limit theorem and the sample mean would have the following distribution:

\bar X \sim N (\mu, \frac{\sigma}{\sqrt{n}})

And for this case we want to find this probability:

P(\bar X >981.7)

And we can use the z score formula given by:

z= \frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}

And replacing we got:

z = \frac{981.7 -997}{\frac{62}{\sqrt{73}}}= -2.108

And we can use the normal standard distribution table or excel and with the complement ruler we got:

P(z>-2.108) =1- P(z

A golfer exerts a force of 15.0 N on a golf ball that has a mass of 0.42 kg. What is the golf
Gala2k [10]

Answer:

35.71m/s²

Step-by-step explanation:

using the formula force(F)=mass(m)×acceleration(a)

a =

\frac{f}{m}

F=15.0N

m=0.42kg

a=?

a=15÷0.42

a=35.71m/s²
