Which of the following expressions can be used to find how many cubes with edge length of 1/3 unit fit in a prism that is 5 unit

mash [69]

Answer:

5400 cubes can be fit into the prism.

Step-by-step explanation:

We are given the dimensions of prism as:

5 units by 5 units by 8 units i.e. 5 units×5 units×8 units.

Hence, the volume of the prism is given by:

Volume of prism=5×5×8=200 cubic units

Also the edge length of cube is given by= 1/3 unit.

Hence volume of 1 cube=

Hence volume of 1 cube= (1/27) cubic units.

Let 'n' cubes can be fitted into the prism.

Hence we have the relation as:

Volume of prism=n×Volume of 1 cube.

200=n×(1/27)

n=200×27

n=5400

Hence 5400 cubes can be fitted into the prism.

The following confidence interval for the population proportion for how many U.S. adults do not get enough fruits and vegetables

Zielflug [23.3K]

Answer:

The interval is constructed at 93% confidence.

Step-by-step explanation:

Confidence interval concepts:

A confidence interval has two bounds, a lower bound and an upper bound.

A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.

The margin of error is the difference between these two bounds, divided by 2.

Confidence interval of proportions concepts:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

The margin of error is:

$M = z\sqrt{\frac{\pi(1-\pi)}{n}}$

In this problem, we have that:

2050 people, so n = 2050.

Lower bound: 0.878

Upper bound: 0.903

$\pi = \frac{0.878 + 0.903}{2} = 0.8905$

$M = \frac{0.903 - 0.878}{2} = 0.0125$

Confidence level:

We have to find z.

$M = z\sqrt{\frac{\pi(1-\pi)}{n}}$

$0.0125 = z\sqrt{\frac{0.8905*0.1095}{2050}}$

$0.0069z = 0.0125$

$z = \frac{0.0125}{0.0069}$

$z = 1.81$

$z = 1.81$ has a pvalue of 0.965.

That is:

$]1 - \frac{\alpha}{2} = 0.965$

$\frac{\alpha}{2} = 0.035$

$\alpha = 2*0.035$

$\alpha = 0.07$

Finally

$1 - \alpha = 1 - 0.07 = 0.93$

The interval is constructed at 93% confidence.

How do you convert .3125 to 5/16

Lilit [14]

Answer: 625

Step-by-step explanation:

Here are the steps to convert .3125 into fraction form:

First we write .3125 as

.3125

1

Now we multiply both the numerator and denominator by 10 for each digit after the decimal point:

.3125

1

=

.3125 x 10000

1 x 10000

=

3125

10000

In order to reduce the fraction we find the Greatest Common Factor (GCF) for 3125 and 10000. Keep in mind a factor is just a number that divides into another number without any remainder.

The factors of 3125 are: 1 5 25 125 625 3125

The factors of 10000 are: 1 2 4 5 8 10 16 20 25 40 50 80 100 125 200 250 400 500 625 1000 1250 2000 2500 5000 10000

The Greatest Common Factor (GCF) for both 3125 and 10000 is: 625
