Answer:

  A  figure 1

Step-by-step explanation:

The given equation is in slope-intercept form:

  y = mx + b . . . . . . where m is the slope and b is the y-intercept

The slope and y-intercept in your equation are both 2. That means the graph crosses the y-axis at y=2 (above the x-axis), and has a positive slope (goes up to the right.

The two top graphs, figures 1 and 2, show lines with positive slope. Only figure 1 shows a graph with positive slope and a positive y-intercept.

Answer:

Answer:

Answer:C = 8

Answer:C = 8Step-by-step explanation:

-2(4c+16)^1/4+2=-2

Move the constant to the right and change the sign

-2(4c+16)^1/4= -2-2

transform expression

[tex] - 2 \sqrt[4]{4c - 16} = - 4[/tex]

Divide each side by -2

[tex] \sqrt[4]{4c - 16 } = 2[/tex]

raise both side of the equation by power of 4

4c-16=16

move constant to the right and change the sign

4c=16+16

4c=32

THEN DIVIDE BOTH SIDES BY 4

C = 8

The median is B. 2.5

Step-By-Step Explanation:

The dot plot goes by the data

1 2 2 3 3 4

those are six numbers in total!

Since 6 is an even number we'd need to find out the number in between the two numbers in the middle.

In this case that would be 2 and 3.

The number in the middle of 2 and 3 is 2.5

Answer:

awnser is 36

Step-by-step explanation:

Answer:  x = 37

Step-by-step explanation:

you can use the pythagorean theorem to solve this:

[tex]a^{2} + b^{2} = c^{2}[/tex]

'a' and 'b' in the equation is referring to the legs of the right triangle, or the sides adjacent to the hypotenuse (which is the side opposite the right angle)

plug in the legs into the equation and you get :

[tex]12^{2} + 35^{2} = x^{2}[/tex]

now to solve that we just square 12 and 35 and you get

144 + 1225 = [tex]x^{2}[/tex]

1369 =  [tex]x^{2}[/tex]

x = [tex]\sqrt{1369}[/tex]

x= 37

Answer:

20

Step-by-step explanation:

180-100

80=(x+3x)

4x=80

x=20

Answer:

The answer is 40.

Step-by-step explanation:

If you do 40 x 5 the answer you get is 200. Which from there you can do 40 x 7 and get 280 which 280 - 200 is 80. Thus meaning the number would be 40.  Hope this helps!

Answer:

1. 54 = 0.6x

2. 90 dollars (see below)

Step-by-step explanation:

54 = 0.6x

0.6 is the decimal equivalent of 60%

Divide both sides by 0.6:

54/0.6 = 0.6x/0.6

90 = x

The probability distribution for a random variable x is given in the table x > 5 is 0.5.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

We are given that;

The table

Now,

Using these facts, we can find the probability that x > 5 from the given table:

The possible values of x that are greater than 5 are 10, 15, and 20. We need to add their probabilities to get the probability of x > 5.

The probability of x = 10 is 0.25, the probability of x = 15 is 0.1, and the probability of x = 20 is 0.15. Adding them together, we get:

P(x > 5) = P(x = 10) + P(x = 15) + P(x = 20)

P(x > 5) = 0.25 + 0.1 + 0.15

P(x > 5) = 0.5

Therefore, the probability will be 0.5.

Speedometer

Step-by-step explanation:

Mainly used to determine the speed of a vehicle

Given:

A figure of a right triangle whose altitude divides the opposite in two segments of 8 and 4 units.

The measure of the altitude is n.

To find:

The value of n.

Solution:

According to the altitude on hypotenuse theorem, the altitude on the hypotenuse of a right triangle is geometric mean of two segments of the hypotenuse.

Let the altitude h divides the hypotenuse in two parts with measure a and b, then

[tex]\dfrac{h}{a}=\dfrac{b}{a}[/tex]

[tex]h^2=ab[/tex]

[tex]h=\sqrt{ab}[/tex]             [Because side length cannot be negative]

In the given figure, the altitude is n and it divides the hypotenuse in two segments of 8 units and 4 units.

Using altitude on hypotenuse theorem, we get

[tex]\dfrac{n}{8}=\dfrac{4}{n}[/tex]

[tex]n^2=4\times 8[/tex]

[tex]n^2=32[/tex]

[tex]n=\sqrt{32}[/tex]

Therefore, the measure of altitude is [tex]n=\sqrt{32}[/tex] units.

Answer:

73  is total amount

Step-by-step explanation:

Have a great day!

Answer:

Option D

Step-by-step explanation:

From the figure attached,

Measure of the opposite side = 17

Measure of the adjacent side = [tex]x[/tex]

Measure of the hypotenuse = [tex]y[/tex]

Measure of the angle = [tex]30^0[/tex]

By applying sine rule in the given right triangle,

sin(30°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

[tex]\frac{1}{2}=\frac{17}{y}[/tex]

[tex]y=34[/tex]

By applying cosine rule in the given triangle,

cos(30°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

[tex]\frac{\sqrt{3}}{2}=\frac{x}{y}[/tex]

[tex]\frac{\sqrt{3}}{2}=\frac{x}{34}[/tex]

[tex]x=17\sqrt{3}[/tex]

Therefore, Option D will be the answer.

Answer:

1/2

Step-by-step explanation:

Total -- 6 people

3 people -- 3/6 = 1/2

Therefore, the answer is 1/2

The probability that a randomly selected person will have red hair for this case is obtained  being 1/2 (in fraction form) or 0.5 (in decimal form).

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]

where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

For this case, we're given that:

We can assume that all the people are equally likely to get selected for this case as selection was done randomly, so all of the 6 people was likely to get chosen without bias.

Now, let we take:

E = event of selecting a red hair person

Then, the number of ways a selection ends up making E happen = 3 (as there are 3 people with red hair, so any of those 3 getting selected will make E happen).

Total number of ways selection can be done = 6 (as selection is done from those 6 people).

Thus, we get:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)} = \dfrac{3}{6} = \dfrac{1}{2} = 0.5[/tex]

Thus, the probability that a randomly selected person will have red hair for this case is obtained  being 1/2 (in fraction form) or 0.5 (in decimal form).
