Answer:

$\{-2,-1,1,2,4\}$

Step-by-step explanation:

Given

The attached graph

Required

Determine the range of the graph

First, we list out the coordinate of each point on the graph:

The points are:

$\{(-4,-1),(-3,-2),(-2,2),(1,1),(2,4)\}$

A function has the form: (x,y)

Where

y = range:

From the coordinate points above,

$y = \{-1,-2,2,1,4\}$

Order from least to greatest"

$y = \{-2,-1,1,2,4\}$

Hence, the range are: $\{-2,-1,1,2,4\}$

Two angles are complementary. one angle is 10° less than four times the other angle. find the measures of the angles. what's the

777dan777 [17]

The two angles are complementary, meaning the sum of the two angles equals to 90.
Let the degree of the smaller angle be x.
degree of the larger angle be y.
x+y= 90
y= 4x-10
x+4x-10= 90
5x= 100
x= 20
y= 4(20)-10= 70
And: The degree of the smaller and larger angles are 20 and 70 respectively.

If 100c^2 has a value of 4950 what is the value of 100c98

N76 [4]

Answer:

$100(49.5)^{49}$

Step-by-step explanation:

Let's solve $100c^2=4950$

Divide both sides by 100:

$c^2=49.5$

Take the square root of both sides:

$c=\sqrt{49.5}$ (I did not keep the negative value because it doesn't matter since we are only considering even powers of $c$ .)

So now let's plug it into:

$100c^{98}$

$100(\sqrt{49.5})^{98}$

$100(49.5)^{49}$

Find the exact value of (1 7/9)^1/2

sweet [91]

I assume you mean the mixed number 1 + 7/9.

As an improper fraction, we have

1 7/9 = 1 + 7/9 = 9/9 + 7/9 = (9 + 7)/9 = 16/9

Then the square root of this is

√(1 7/9) = √(16/9) = √(4²/3²) = √((4/3)²) = 4/3

A bowl contains 6 green grapes, 10 red grapes, and 8 black grapes. Which of the following is the correct

irina1246 [14]

Using the it's concept, the correct calculation for the probability of choosing a red grape and then without putting the red grape back into the bowl, choosing a green grape is:

$p = \frac{5}{2} \times \frac{1}{23} = \frac{5}{46}$

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem, we have that there is a total of 6 + 10 + 8 = 24 grapes. For the first grape, 10 are red, hence the probability that the first grape is red is:

$pR = \frac{10}{24} = \frac{5}[12}$

For the second grape, considering that the first was red and was removed, there will be 23 grapes, out of which 6 will be green, hence the probability that the second grape is green is:

$pG = \frac{6}{23}$

Hence the correct expression is found as follows:

$p = pR \times pG = \frac{5}{12} \times \frac{6}{23} = \frac{5}{2} \times \frac{1}{23} = \frac{5}{46}$
