(help me pls) Use the bar graph to find the experimental probability of rolling a number less than 7. What is the experimental probability?

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

Answer:

183 acres.

Step-by-step explanation:

To find the answer, we must find 0.3% of 61,000.

61,000 × 0.3 = 183

0.3% of 61,000 is 183. The answer is 183 acres of old-growth trees. Hope it helped! :D

Haven't done this kinda problem in a while but I got 4/3 cm/s

Step-by-step explanation:

Using the coordinates given i put them into the formula:

        y1  -  y2

m=_________

        x1  -  x2

That gave me -16/-12, I simplified & got 4/3.

Answer: There is 5 non blue sock in Josh's drawer

Step-by-step explanation:

The denominator shows the total of nonblue and blue socks. So there are 7 non-blue and blue socks in the drawer after he removes 3 non blue socks.To find how many non-blue where in the drawer originally you need to find how many non blue are in the draw after removing the three. So you subtract 7 from 5 which gives you 2. So there are 2 non-blue socks in the drawer after removing the three. Now you need to find how many non-blue were there before he removed the three. So add the 3 non blue socks that he removed to the two that were there after which gives you five.

Answer:B. 1/2m + 4 = 20

Step-by-step explanation: you match up using key words such as more than is plus , half is 1/2 .

Answer:m, in Bryan’s homeroom is:

B. 1/2m + 4 = 20

Step-by-step explanation:

The problem states that "four more than half of the students in Bryan’s homeroom have tickets to attend the school’s musical", and that "20 students from that class have tickets". Let m be the total number of students in Bryan's homeroom.

Answer:

The zeros of a rational expression are the places where the numerator is zero:

4x = 0

x = 0

divide by 4

Answer: 187

Step-by-step explanation:

I don't think this might be right, but I rounded 1.63 gallons to 1.60 gallons. After, I decided to divide that bye the population of the

country, (300 million), which gave me 187.5. I then rounded it to 187.

Was a bit confused on this myself, but hopefully its right.

Answer:

c. 2/13

Step-by-step explanation:

The bag starts with 8 red marbles, 4 green marbles, and 2 yellow marbles. Since he draws a red marble from the bag and does not replace it, there will be one less marble.

So now there are 7 red marbles, 4 green marbles, and 2 yellow marbles. Add the number of marbles together and then find the probability of drawing a yellow marble.

7+4+2 = 13

2/13

So the probability of Bill drawing a yellow marble would be 2/13.

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Answer:

The jar of chermical contains 66g of Zinc.

Step-by-step explanation:

The ratio of Zinc to Copper is 3 : 13

A jar of the chemical contains 286g of copper.

Let the mass of the Zinc be xg.

13/3 = 286/x

x = 3A286/13= 66g

So the jar of chemical contains 66g of Zinc.

Answer:

1/2 pi

Step-by-step explanation:

This is 1/4 of a circle

Find the  circumference and multiply by 1/4

1/4 C

1/4 ( 2*pi*r)  where r is the radius

The radius is 1

1/2 pi*1

1/2 pi

Answer:

Step-by-step explanation:

A full circle has a circumference of 2*pi * r

r = 1

so Full Circle = 2 * PI

1/4 Circle = 2*pi / 4 = 1/2 pi

The length of the arc length = 1/2 pi

Just in case you prefer the more numerical answer, 1/2 * 3.14 = 1.57

Answer:

b)

\(x^{2} +\frac{b}{a} x+(\frac{b}{2 a} )^{2} = \frac{-c}{a} + (\frac{b}{2 a}) ^{2}\)

Step-by-step explanation:

Step(i):-

Given quadratic equation ax² + bx + c = 0

step(ii):-

ax² + bx = -c

Step(iii):-

Dividing 'a' on both sides , we get

\(\frac{ax^{2} +bx }{a} = \frac{-c}{a}\)

\(x^{2} + \frac{bx}{a} = \frac{-c}{a}\)

Step(iv):-

Adding  \((\frac{b}{2 a} )^{2}\) on both sides , we get

\(x^{2} +\frac{b}{a} x+(\frac{b}{2 a} )^{2} = \frac{-c}{a} + (\frac{b}{2 a}) ^{2}\)

Step-by-step explanation:

I learned this formula in math last year

Answer:

75 hairs/ day =  525 hairs / week

Step-by-step explanation:

so your base question for this is 75 hairs/ day =? h/ week. how? if the dog is losing 75 hairs per day, then you would do 75 x 7 becuase there are 7 days in a week. the answer to that would give you how many hairs the dog was losing per week. (see attached image for reference)

To solve the equation for y, we need to get y by itself on one side of the equation.

The first step is to get rid of the fraction on the right side of the equation by multiplying both sides by 4:

4y + 28 = x + 16

Then, we need to move the x term to the left side of the equation by subtracting x from both sides:

4y + 28 - x = 16

Then, we need to move the constant term 28 to the left side of the equation by subtracting 28 from both sides:

4y - x = -12

Finally, we have the equation in the form y = (1/4)x - 3, so the solution for y is y = (1/4)x - 3

It is important to note that in this solution we have used the distributive property and followed the order of operations to get to the final result, if you don't follow this steps you might get a different result.
