Does the graph represent a function?
fomenos

Hey there!

No, the graph is not a function because it has two of the same inputs, (7, -6) and (7, -7).

It also can't be a linear function because the graphs are not pointed to form a straight line.

Hope this helps!

Have a great day!

For each of the following statements, identify the number that appears in boldface type as the value of either a population char
Alex Ar [27]

Answer:

a) 88% is a population characteristic.

Step-by-step explanation:

A population characteristic, also known as population parameter, describes a characteristic about the entire population of variables (usually numerically). Basically, it is a description (usually numerical) about a group of variables, obtained from the total population of such a variable.

WHILE

A statistic describes that same characteristic, only that it is obtained from a sample of variables taken from the population.

For the question above, a department notices that 88% of ALL their customers who use the store's credit plan pay their bills on time. It is evident that this is a population charasteristic, as it is obtained from examining the entire population of customers.

Hope this Helps!!!

You hike 190 meters up a steep hill that has a 33∘ angle of elevation as shown in the diagram.
erik [133]

Answer:

b = 159 m

a = 103 m

angle B is 57 degrees

Step-by-step explanation:

Let’s start with getting the measure of angle B

Mathematically, since we have a right triangle , we have to subtract the given angle from 90 to get the other acute angle

So we have the measure of B as;

90-33 = 57 degrees

To get the value of a, we use the appropriate trigonometric ratio

a faces the angle 33, that makes it an opposite to that angle

190 faces the right angle and that makes it the hypotenuse

Mathematically , the relationship between the two is that trigonometrically, they are related by the sine which is the ratio of the opposite to the hypotenuse

so, we have it that;

sine 33 = a/190

a = 190 * sine 33

a = 103 m

to get b, it is adjacent to the given angle

So with the hypotenuse, the ratio between it and the hypotenuse is the cosine

so;

cos 33 = b/190

b = 190 * cos 33

b = 159 m

3x – 3y = -9<br> 4x + 4y= 12<br><br><br> show me the steps for substitution?
Alchen [17]

Answer:

y=3 and x=0

Step-by-step explanation:

3x−3y=−9. i'm going to solve for x.

3x−3y<em>+3y</em>=−9<em>+3y</em>

3x=3y−9

3x/3=(3y-9)/3  to isolate x we have to divide everything by 3

x=y−3

so now that we have x we can substitute it in 4x+4y=12

4(y-3)+4y=12

4y-12+4y=12

8y-12=12

8y-12<em>+12</em>=12<em>+12</em>

8y=24

8y/8=24/8

y=3

we have y which equals 3, so now we can substitute it into any equation so solve for x again.

3x – 3y = -9

3x-3(3)=-9

3x-9=-9

3x-9+9=-9+9

3x=0

3x/3=0/3

x=0

so, final answers are y=3 and x=0

checking our work:

3(0)-3(3)=-9

0-9=-9

-9=-9 true

4(0)+4(3)=12

0+12=12

12=12 true

Please answer it in two minutes
Yakvenalex [24]

Answer:

21/20, or 1.05.

Step-by-step explanation:

In this case, the measure of angle R is the same as angle V.

To find the tangent of a triangle, you do opposite over adjacent.

So, the tangent of angle V is 21 / 20.

That means that tan(R) = 1.05.

Hope this helps!
