Answer:

Consecutive Interior

Step-by-step explanation:

Angles 4 and 6 are both Consecutive Interior Angles.

Since the definition of CI is:

When two lines are crossed by another line (called the Transversal): The pairs of angles on one side of the transversal but inside the two lines are called Consecutive Interior Angles.

A picture to represent this is:

Which one of these is the identity for addition?

Sedaia [141]

Answer:

Zero

Step-by-step explanation:

In math, an identity is a number, n, that when added to other numbers, gives the same number, n. The additive identity is always zero. This brings us to the identity property of addition, which simply states that when you add zero to any number, it equals the number itself

What do i do from here on #1??? plz help immediately thank u!!

hammer [34]

Pablo has to paint $\frac{1}{3}$ more murals.
Painted mural to jar of paint ratio: $\frac{2}{3} paintedmurals: \frac{4}{5} jarofpaint$
Simplify the ratio.
$\frac{1}{3} paintedmurals: \frac{2}{5} jarsofpaintused$
Pablo needs 2/5 jars of paint per each 1/3 painted murals
$3*\frac{2}{5}$
$\frac{6}{5}$

About 10% of people in the United States are left handed. Suppose we take a sample of 120 U.S. Residents, and let X = the number

olganol [36]

Answer:

1) $E(X) = np = 120*0.1 =12$

$SD(X) = \sqrt{np(1-p)}= \sqrt{120*0.1*(1-0.1)} =3.286$

For this case we can interpret that the expected variation around the mean is about 3.3 people approximated

2) $P(X\geq 16)$

And we can use the normal approximation given by:

$X \sim N(12, \sigma =3.286)$

And we can use the z score formula given by:

$z = \frac{X -\mu}{\sigma}$

And if we find the z score for 16 we got:

$z = \frac{16-12}{3.286}= 1.217$

And we can find this probability using the normal standard distribution or excel and we got:

$P(Z>1.217) = 0.112$

3) For this case we can conclude that the probability to find 16 or more individuals left handed in a sample of 120 is about 0.112 or 11.2%

Step-by-step explanation:

Let X represent the random variable for the number of residents who are left handed

And for this case we can model this variable with this distirbution:

$X\sim Binom(n= 120 , p =0.1)$

Part 1

The mean is given by:

$E(X) = np = 120*0.1 =12$

And the deviation would be:

$SD(X) = \sqrt{np(1-p)}= \sqrt{120*0.1*(1-0.1)} =3.286$

For this case we can interpret that the expected variation around the mean is about 3.3 people approximated

Part 2

We want to calculate this probability:

$P(X\geq 16)$

And we can use the normal approximation given by:

$X \sim N(12, \sigma =3.286)$

And we can use the z score formula given by:

$z = \frac{X -\mu}{\sigma}$

And if we find the z score for 16 we got:

$z = \frac{16-12}{3.286}= 1.217$

And we can find this probability using the normal standard distribution or excel and we got:

$P(Z>1.217) = 0.112$

Part 3

For this case we can conclude that the probability to find 16 or more individuals left handed in a sample of 120 is about 0.112 or 11.2%

What is the measure of angle x?<br> A.101<br> B.158<br> C.44<br> D.79

miskamm [114]

You would solve this problem by subtracting 22 from 180, and then dividing this number, 158, by 2. You would end up getting 79, so the answer is D.

Which is the graph of f(x) =2(3)x^

pentagon [3]

Answer:

the first graph on the left

Step-by-step explanation:

Substitute the x- coordinate of the point indicated on the graph into the equation and check that this gives the value of the y- coordinate

(1, 6) ⇒ f(1) = 2 $(3)^{1}$ = 2 × 3 = 6 ← correct

(1, 9) gives y = 6 ≠ 9 ← not valid

(2, 8) ⇒ f(2) = 2 $(3)^{2}$ = 2 × 9 = 18 ≠ 8 ← not valid

(2, 12) gives y = 18 ≠ 12 ← not valid
