120 - 36 as a product with the GCF as a factor. True, we can factor out the GCF and we'll have a product:

GCF(120,36) = GCF(5(24),36)=GCF(5(12)(2),12(3)) = 12

We can factor that out and get:

120 - 36 = 12(10 - 3) = 12(7)

Answer: TRUE

How to find the GCF of three numbers.

There are a couple different ways; the obvious way is to find the GCF of the first two and then then GCF of the result and the third.

The other way is to prime factorize all three numbers; for each prime factor count how many times it occurs in each input. In the GCF it will occur the minimum of those three. Multiply the resulting powers of prime factors to get the GCF.

GCF(60,90) = GCF(30(2), 30(3)) = 30

60 + 90 = 30(2 + 3)

Xiao missed a factor of ten in the GCF.

Find the value of cos x if the value of sin x=3/5 and x is acute angle

just olya [345]

Sin = opposite / hypotenuse
cos = adjacent / hypotenuse

using pythagoras theorem =

adjacent = 5^2-3^2
= 16
= square root 16
=4

cos x = 4/5

What are the intercepts?

klio [65]

Answer:

In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system.[1] As such, these points satisfy x = 0.

$140 for 18ft squared=?????

andrew11 [14]

Unit rate means how much does it cost for 1 unit
140 for 18ft^2

divide by 18
140/18=7.77777777777777
so the unit rate is $7.78 per square foot

Assume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund

ser-zykov [4K]

Testing the hypothesis, it is found that since the p-value of the test is 0.0042 < 0.01, it can be concluded that the proportion of subjects who respond in favor is different of 0.5.

At the null hypothesis, it is tested if the proportion is of 0.5, that is:

$H_0: p = 0.5$

At the alternative hypothesis, it is tested if the proportion is different of 0.5, that is:

$H_1: p \neq 0.5$

The test statistic is given by:

$z = \frac{\overline{p} - p}{\sqrt{\frac{p(1 - p)}{n}}}$

In which:

$\overline{p}$ is the sample proportion.
p is the value tested at the null hypothesis.
n is the sample size.

In this problem, the parameters are given by:

$p = 0.5, n = 483 + 398 = 881, \overline{p} = \frac{483}{881} = 0.5482$

The value of the test statistic is:

$z = \frac{\overline{p} - p}{\sqrt{\frac{p(1 - p)}{n}}}$

$z = \frac{0.5482 - 0.5}{\sqrt{\frac{0.5(0.5)}{881}}}$

$z = 2.86$

Since we have a two-tailed test(test if the proportion is different of a value), the p-value of the test is P(|z| > 2.86), which is 2 multiplied by the p-value of z = -2.86.

Looking at the z-table, z = -2.86 has a p-value of 0.0021.

2(0.0021) = 0.0042

Since the p-value of the test is 0.0042 < 0.01, it can be concluded that the proportion of subjects who respond in favor is different of 0.5.
