Answer:
B.) 6
Step-by-step explanation:
Given the data:
64 53 60 60 56 58 51 55 60
Reordered data : 51, 53, 55, 56, 58, 60, 60, 60, 64
Interquartile range = upper quartile (Q3) - Lower quartile (Q1)
Q3 = 3/4(n+1)th term
n = sample size = 9
Q3 = 3/4(9+1) = 3/4 (10) = 30/4 = 7.5 th term
Q3 = 60
Q1 = 1/4 (n + 1) th term
Q1 = 1/4(9+1) = 1/4 (10) = 10/4 = 2.5 th term
Q1 = (53 + 55) / 2
Q1 = 54
Q3 - Q1
60 - 54 = 6

the notebook computer?
PLEASE HELP ME WITH THIS QUESTION AND PROVIDE AN EXPLANATION PLEASE
FIND A UNIT RATE!!!!
Answer:
No
Step-by-step explanation:
No, it is not because the 3 dollars is a steady price. A expression will look like 7n+3. Since the 3 dollars is a steady price you can never have a unit rate.
Answer:
It's proportional
Step-by-step explanation:
10-3=7 7/1 = 7

Solve each equation.
1/3a = -5 a = ?
12 - b = 12.5 b = ?
-0.1 = -10c c = ?
Answer:
a = -15, b = -.5, c = -1
Step-by-step explanation:
1/3a = -5 --> multiply each side with 3 --> a = -15
12 - b = 12.5 --> subtract 12 from both sides --> -b = .5 --> multiply each side with -1 to get b positive --> b = -.5
.1 = -10c --> multiply each side with -10 --> c = -1
what is the slope of the the line shown below?
Answer:
The answer is A. -2/7
Step-by-step explanation:
Write the equation of the line in the slope intercept form if the line passes through (3,5) and (5,9) show all your work
Answer:
slope (m)= y2-y1 /x2 -x1
Step-by-step explanation:
or m= ((9-5)/ (5-3)
or,m= 4/2
or,m =2
Step-by-step explanation:
m(slope)=(Y2-Y1)/(X2-X1)
m=(9-5)/(5-3)
m=2

The temperature was -5°F when Tiffany woke up in the morning. By noon, the temperature was O'F. How many degrees did the temperature
change?
Answer:
+5℉
Step-by-step explanation:
To get out of the negative you need to add, it was -5 now its 0. 5 degrees was added.
Answer: +5 °F
Step-by-step explanation:5°. 5°F to 0°F means subtracting 5 to get 0.
find the value of x
Answer:
20 degrees
Step-by-step explanation:
The sum of angle on a straight line is 180 degrees
x+20 + 7x = 180
8x + 20 = 180
8x = 180 -20
8x = 160
x = 160/8
x = 20
Hence the value of x is 20 degrees
which equation represents the line that passes through the points (3,4) and (1,-2)
Answer:
y = 3x - 5
Step-by-step explanation:
First, you find the slope by finding the change in y and dividing that by the change in x of the two points.
-2 - 4 = -6, so -6 is the change in y.
1 - 3 = -2, so -2 is the change in x.
Then, since slope is change in y divided by change in x, you have -6/-2 = 3.
So far your equation is y = 3x + b and you're trying to find b to finish the equation.
To do this, you can pick one of the points and substitute the x and y values into the equation to find what value of b makes it true. Using (1, -2) we have
y = 3x + b --> -2 = 3(1) +b
-2 = 3 + b
b = -5
That means your equation is y = 3x - 5
Solve the equation. 5t^3 +40t^2 = -80t
Answer:
-5t2 + 40t - 3
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 5 • 3 = 15
Step-2 : Find two factors of 15 whose sum equals the coefficient of the middle term, which is -40 .
-15 + -1 = -16
-5 + -3 = -8
-3 + -5 = -8
-1 + -15 = -16
1 + 15 = 16
3 + 5 = 8
5 + 3 = 8
15 + 1 = 16

The 2020 senior class from a high school raised funds for an end of the year prom at Club Dance. It costs $4,000 to rent out Club Dance plus $20 per student for food and drinks.
Write an equation for the number of students could attend if the senior class raised 11,000 dollars.
Answer:
4000 + 20x = 11,000
Step-by-step explanation:
4000 + 20x = 11,000
20x = 7,000 (subtract 4,000 from 11,000)
7,000/2 = 3500

Answer:The answer is 12.8
Step-by-step explanation:
8 and 10 are the side lengths so you would put that check mark thingy and then under it you put 8 squared and 10 squared and then you add it up. If you have the side length and the right length (which is the x) you would subtract because the right length is the longest.

Find a cubic function with the given zeros.
[tex]\sqrt{5}, - \sqrt{5} , -7[/tex]
f(x) = [tex]x^{3} - 7x^{2} - 5x - 35[/tex]
f(x) = [tex]x^{3} + 7x^{2} - 5x + 35[/tex]
f(x) = [tex]x^{3} + 7x^{2} - 5x - 35[/tex]
f(x) = [tex]x^{3} + 7x^{2} + 5x - 35[/tex]
Answer:
The third: f(x) = x³ + 7x² - 5x - 35Step-by-step explanation:
[tex]f(x)=(x-\sqrt5)(x+\sqrt5)(x+7)\\\\f(x)=(x^2+x\sqrt5-x\sqrt5-(\sqrt5)^2)(x+7)\\\\f(x)=(x^2-5)(x+7)\\\\f(x)=x^3+7x^2-5x-35[/tex]
Answer:
C. f(x) = x³ + 7x² - 5x - 35Step-by-step explanation:
Given zeros of cubic function:
√5, -√5 and -7The cubic function has standard form:
f(x) = ax³ + bx² + cx + dWithout multiplying lets find the value of a, b, c and d:
a = 1 as all the answer optionsSum of the roots
-b/a = √5 - √5 - 7 = -7, so b = 7Sum of the products of the roots (taken two at a time)
c/a = √5*(-√5) + √5*(-7) + (-√5)(-7) = - 5, so c = -5Product of the roots
- d/a = √5*(-√5)*(-7) = 35, so d = -35So the cubic function is:
f(x) = x³ + 7x² - 5x - 35Correct option is C

Dana bikes 10 miles in 50 minutes at this rate how far will she bike in 90 minutes
Answer:
18 miles
Step-by-step explanation:
the ratio is miles/minute
10/50=0.2
so no just multiply the amount of minute you want 0.2*90= 18 miles
Answer and Step-by-step explanation:
In an hour and a half, Dana would go 18 miles since she's going a mile at regular intervals, so if she's trekking for an additional forty minutes, she will bicycle 8 miles. This implies that you'd increase five minutes by 8 miles (recall it's a mile for every 5 minutes) and that would give you forty. At that point simply add that to the 50 minutes she's been cycling as of now.

How to solve this
3 = (2x + 8)/3
Answer:
x = 1/2
Step-by-step explanation:
First you want to get rid of the fraction, so you can multiply both sides of the equation by 3.
9 = 2x + 8
Then, subtract 8 from both sides to get x by itself.
1 = 2x
Finally, divide both sides by 2 so you only have one x
1/2 = x
This means that the answer is x = 1/2.
Answer:
x=1/2 or 0.5
Step-by-step explanation:
(2x+8)/3=3
(2x+8)=3x3
(2x+8)=9
2x=9-8
2x=1
x=1/2
x=0.5
