Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
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:
B. -19 4/3
Step-by-step explanation:
Opposite numbers add to 0.
For example, -1 and 1 are opposite since -1 + 1 = 0
Let's say x is the answer:
19 4/3 + x = 0
19 4/3 - (19 4/3) + x = 0 - (19 4/3) => subtract 19 4/3 on both sides to isolate x
0 + x = -19 4/3
x = -19 4/3 ==> Answer is B

Answer: The expression would be 2b+7
Step-by-step explanation:
b will be the number of blue beads for the bracelet.
The number of red beads will be represented as b + 7.
Determine the expression for the total number of beads.
Then we can written it as,
= b + (b +7)
= 2b + 7.
After you multiply a number by 9 and subtract the product from 300, the difference will be 183. Find the number.
Answer:
x=13
Step-by-step explanation:
300-(9x) =183
300-183=9x
117=9x
x=117/9
x=13
check:
300-117=183

A farmer planted corn in two different fields. He planted 500 seeds of regular corn in Field A and 500 seeds of experimental corn in Field B. At
harvest time, more ears of corn had grown in Field A than in Field B. The farmer concluded that more corn grew in Field A because of the type of corn planted.
Choose two other possible variables that could have caused more corn to grow in Field A.

Apollo traveled 54 leagues in 3 days. Then he tripled his rate. How long would it take him to travel 594 leagues at this new speed?
Answer:
11 days
Step-by-step explanation:
First, you have to find the original rate. Then, multiply that by three. Lastly, take 594 and divide by the tripled number.
54 ÷ 3 = 18
18 x 3 = 54
594 ÷ 54 = 11
Determine the discriminant for the quadratic equation 0=-2x2+3. Based on the discriminant value, how many real number solutions does the equation have?
Discriminant = b2-4ac
0
1
2
24
Answer:
Option D.
The discriminat is equal to 24 which
Step-by-step explanation:
The quadratic equation is
-2x² + 3 = 0
Discriminat in quadratic equation tells us the number of solution a quadratic equation has.
For example, the quadratic equation
Ax² + bx + c = 0 will have a discriminat of b² - 4ac.
b² - 4ac is equal to the value of the discriminat and equal to the number of solutions the quadratic equation has.
In our question, we have -2x² + 3 = 0
A = -2
B = 0
C = 3
b² - 4ac = 0
Substitute the values into the above equation.
0² - 4(-2 ×3) = 0
0 + -4 × -6 = 0
24 = 0
The discriminat of the equation is 24

Choose the correct answer
Answer:
Its c. c = 50.
Step-by-step explanation:
First, we need to figure out what the equation equals.
7 + 7/7 + 7*7 - 7 = x
PEMDAS
Parentheses, exponents, division/fraction, addition, subtraction.
7/7 = 1. So equation changed into 7 + 1 + 7*7 - 7 = x.
7*7 = 49. So equation changed again into 7 + 1 + 49 - 7.
Lets calculate it. 7 + 1 = 8 + 49 = 57 - 7 = 50. x = 50.
c is the only one who has a calculation of 50.

Answer:
Answer for number 6: $8.10
Step-by-step explanation:
First of all, you start by multiplying 1.59 by 5. $1.59 x 5 = $7.95. Now, all you have to do is add $7.95 and $3.98. $7.95 + $3.98 = $11.90. Now the last this to do is Subtract $11.90 from $20.00. $20.00 - $11.90 = $8.10. You will receive $8.10 if he gives the cashier a $20.00 dollar bill.

Identifying the values a, b, and c is the first step in using the Quadratic Formula to find solution(s) to a quadratic equation.
What are the values a, b, and c in the following quadratic equation?
−6x2 − 8x + 12 = 0
a = −6, b = −8, c = 12
a = 6, b = 8, c = 12
a = 8, b = 12, c = 0
a = −8, b = 12, c = 0
Answer: A!
Step-by-step explanation: The quadratic formula is ax2+bx+c, so you just plug in and see which ones go with the equation, a=-6 (-6x2) b=-8 (+-8 or -8) and c=12 (+12) Hope this helps

Answer:
61
Step-by-step explanation:
13 - 1 = 1212 ÷ 2 = 6Put 6 and 1 together: 61Therefore, the number is 61
Let's check:
6 × 2 = 1212 + 1 = 13The sum of the two digits is 13, and we got that, so we are correct. The number is 61.
Answer:
49
Step-by-step explanation:
let unit digit=x
ten's digit=y
then x+y=13
x=13-y
also x=2y+1
13-y=2y+1
13-1=2y+y
3y=12
y=12/3=4
x=13-4=9
so number =10×4+9=49

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.
You are given a triangle with side lengths of 6, 9, and 12. Is the triangle a right triangle? How do you know?
Answer:
No, it's not
Step-by-step explanation:
You choose the longest side which is 12 and apply the theory of phitagors
The longest side which is the hypotenuse in a right triangle = square root the square sum for each side
So to be a right triangle it should be
\( \sqrt{ {9}^{2} + {6}^{2} } = 10.8 \: \: that \: doesnt \: equal \: 12\)
So it's not a right triangle.
Look at the famous right triangle whose side are 5(hypotenuse), 4, 3
\( \sqrt{ {4}^{2} + {3}^{2} } = 5\)
So it's a right triangle

Find the value of x please :)
Answer:
32 degrees
Step-by-step explanation:
The sum of all angles in a triangle is 180 degrees.
A right angle (The one marked by a small square on the bottom left) measures 90 degrees.
You're given that the other two angles in the triangle measure 58 and x degrees.
To find x, we'll find the sum of all angles, and equate it to 180.
The sum of all angles = 90 + 58 + x = 148 + x degrees
\(148 + x = 180 \text{ // -148}\\\cancel{148 -148} + x = 180 - 148\\x = 32^{\circ}\)
