aniked [119]3 years ago
4 0

Answer:

GCF would be 10

Step-by-step explanation:

GCF, aka <em>the greatest common factor</em> is the biggest number that can be multiplied to get that number. for example, in this situation it would be 1- because 10 can be multiplied to get any of those numbers. 1 x 10 = 10 ; 2 x 10 =20 ; 4 x 10 = 40. hope this helped!!

olga nikolaevna [1]

Answer:

2 feets

Step-by-step explanation:

Given that :

Alli's Initial depth = 6 feets

Number of feets in which Alli rose = 4 feets

Alli's new position relative to the surface of the pool:

Difference of Alli's initial depth and feets risen :

6 feets - 4 feets = 2 feets

Hence, Alli is now 2 feets below the surface of the pool.

~~~15 POINTS~~~
REY [17]
Let's call bicycles 'b' and unicycles 'u'
Note that bicycles have 2 tires, and unicycles have 1 tire.

We can make two equations:

b = u + 8
2b + 1u = 46

Solving the first equation for u, we get:

u = b - 8

Plug that equation into the second, and we get:

2b + (b - 8) = 46

Subtract 2b on both sides.

1(b - 8) = 46 - 2b

Basically, I used b and your question used n.

The correct answer is: D. 1(n - 8) = 46 - 2n.

A computer manufacturing company has sent a mail survey to 2,800 of its randomly selected customers that have purchased a new la
vodka [1.7K]

Answer:

The 96% confidence interval for the population proportion of customers satisfied with their new computer is (0.77, 0.83).

Step-by-step explanation:

We have to calculate a 96% confidence interval for the proportion.

We consider the sample size to be the customers that responded the survey (n=800), as we can not assume the answer for the ones that did not answer.

The sample proportion is p=0.8.

p=X/n=640/800=0.8

The standard error of the proportion is:

\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.8*0.2}{800}}\\\\\\ \sigma_p=\sqrt{0.0002}=0.014

The critical z-value for a 96% confidence interval is z=2.054.

The margin of error (MOE) can be calculated as:

MOE=z\cdot \sigma_p=2.054 \cdot 0.014=0.03

Then, the lower and upper bounds of the confidence interval are:

LL=p-z \cdot \sigma_p = 0.8-0.03=0.77\\\\UL=p+z \cdot \sigma_p = 0.8+0.03=0.83

The 96% confidence interval for the population proportion is (0.77, 0.83).
