Answer:

C

Step-by-step explanation:

unimodel: A unimodal distribution is a distribution with one clear peak or most frequent value. The values increase at first, rising to a single peak where they then decrease.

Ok soo for the first one we're gonna use sine, (remember SOH CAH TOA) since we know the value of the hypotenuse.

Sin37° = x/9.3

0.6018=x/9.3

x= 5.59674

The last one we'll use cosine because we know the value of the side adjacent to 96°.

Cos42°=5.1/y

0.7431=5.1/y

y= 6.86272692

I assume it has you round your answers to the nearest tenth so the first one would be 5.6 and the second would be 6.9 .

Hope this helps!

Answer:

[tex]y= 2x - 3[/tex]

Step-by-step explanation:

rearrange equation into slope-intercept form

isolate y by subtracting x from both sides

[tex]2y=-x+14[/tex]

divide two from both sides

[tex]y= -\frac{1}{2}x+7[/tex]

here, we can note that the slope is -1/2, which to be perpendicular means it needs the negative inverse of slope

in other words, flip the fraction and take the negative of it, which gives m = 2

therefore plugging the given coordinates (6,9) and slope m = 2 into

[tex]y-y_{1} = m(x-x_{1} )[/tex]

therefore, we get

[tex]y-9=2}(x-6)[/tex]

distribute 2

[tex]y-9 = 2x - 12[/tex]

add 9 to both sides

[tex]y= 2x -3[/tex]

Answer:

y = 2x-3

Step-by-step explanation:

find the slope intercept first by isolation the y in the first equation

then because its asking for the perpendicular equation you will flip the x in the slope intercept equation.

now youll want to plug in (6,9) into y = 2x + a

and you will get -3

then youll have your answer

Answer:

Step-by-step explanation:

it doesn't really say what the "face" is, but i'll guess that it's the part marked in yellow?  if that's the case then it's just  10 * 10  twice for each of the squares.  Really you couldn't see that?  :/      200 is the answer

Answer: 26%

Step-by-step explanation:

20+52+34+71+23= 200

52/200 = 26/100

Answer:

26% of the jelly beans are yellow

Step-by-step explanation:

To find this we add up all the jelly beans which is 200 jelly beans

Then we divide it by the number of yellow jelly beans which is 52/200

which then equals .26. In a percentage that is 26%

Answer:

Employee C

Step-by-step explanation:

A. We have to divide each earning by hour. Therefore, you have to do 180/15. Therefore, he makes 12 dollars per second.

B. We have to divide each earning by hour. Therefore, you have to do 210/20. Therefore, he makes 10.5 dollars per second.

C. We have to divide each earning by hour. Therefore, you have to do 455/35. Therefore, he makes 13.

This means that Employee C has the highest earning per hour.

Answer:

Naman is 12 years old

Step-by-step explanation:

This means his sister is 3 which means in 20 years Naman will be 32 and his sister will be 23. Double 23 and you get 46 and 46 - 32 is 14

Answer: 2.357hrs

Step-by-step explanation:

Rate of dirt removal (rate) = 7/8 tons/hr

Total dirt removed (dirt) = 2 1/16 tons

Each hour, 7/8 tons of dirt will be removed, so if you work for h hours, you will have removed 7/8 * x tons of dirt. You can set up an equation as follows:

7/8 tons/hr * h hr = 2 1/16 tons (see how the units work out to give you tons)

Rearrange and solve for h:

h = (2 1/16) / (7/8) = 33/14 hrs = 2.357hrs

Answer:

2

Step-by-step explanation:

The frequency is how many times the score shows up in the data set

21, 27, 20, 29, 23, 21, 21, 27, 26, 25

27 shows up 2 times so the frequency is 2

Answer:

Sandwich - 2 $ and salad 3.10 $

Answer:

The two other angles are 29 degrees and 61 degrees

Step-by-step explanation:

There are 180 degrees in a triangle. Given this is a right triangle one of the angles is 90 degrees. As in the other two angles have to equal up to 90 degrees. Now we have to find x.

180 - 90 = 90

If x equals 28

28 + 1 = 29

2 x 28 + 5 = 61

29 + 61 = 90

The two other angles are 29 degrees and 61 degrees

Answer:

29 , 61

Step-by-step explanation:

Sum of all angles of a triangle = 180

90 + x + 1 +2x +5 = 180 {Combine like terms}

96 + 3x = 180         {Subtract 96 from both sides}

         3x = 180 - 96

          3x = 84 {Divide both sides by 3}

           x = 84/3

x = 28

x +1 = 28 +1 = 29

2x +5 = 2*28 + 5 = 56 + 5 = 61

Answer:

[tex]\displaystyle f(x)=\frac{10}{169}\left(x-8\right)^2-1[/tex]

Step-by-step explanation:

We can use the vertex form of a quadratic, which is given by:

[tex]\displaystyle f(x)=a(x-h)^2+k[/tex]

Where (h, k) is the vertex.

Since we are given that the vertex is (8, -1), h = 8 and k = -1. Substitute:

[tex]f(x)=a(x-8)^2-1[/tex]

Next, we are given that the parabola passes through the point (-5, 9). So, when x = -5, y = 9:

[tex]9=a((-5)-8)^2-1[/tex]

Solve for a:

[tex]9=a(-13)^2-1[/tex]

So:

[tex]\displaystyle a=\frac{10}{169}[/tex]

So, the equation of our parabola is:

[tex]\displaystyle f(x)=\frac{10}{169}\left(x-8\right)^2-1[/tex]

Answer:

The equation of our parabola would be:

f(x) = 10/169(x - 8)[tex]^{2}[/tex] - 1

Answer:

Step-by-step explanation:

Hi,

So from Andre's perspective, if he receive money that would be positive (cuz that will be adding to his collection) whereas, if he has to give money away that would be negative (cuz he would have to pay out of his pocket).

Think about it like this, people generally feel positive when they receive money and feel negative when they give away money. Apply this same concept.

Therefore,

A) Andre received money so = $25

B) Andre earned money so = $18

C) Andre had to give money away to buy the book so = - $10

D) Zero (0) would mean that he did not gain or lose any money.

Answer:

a. +25

b. +18

c. -10

d. 0 could represent the starting amount.

Step-by-step explanation:

Andy gets money from his uncle, so he is earning money, which makes it a positive.

Similar to b, Andy earns $18. He is earning it, so it is positive.

With C, he is losing money by paying for something, so it is negative.

Answer:

2544 ft

Step-by-step explanation:

First, find the area of the pool.

A= πr²

if we fill in the radius, use 3.14 for pi, and solve for A, that's

A=(3.14)(20.5)²≈1319.585

The area of the pool is roughly 1319.585 ft

Now, we find the area of the triangle

A=(ab)÷2

put in 'a' and 'b' (the triangle legs) and solve

A=(84×92)÷2=3864

Finally, subtract the area of the pool from that of the triangle

3864-1319.585=2544.415 which rounds to 2544 ft

hopefully that helps and you might want to double check but that's what I got :)
