~Divide 4 to both sides
x = 7
Best of Luck!
Answer:
[tex]x=7[/tex]

Find a conversion factor between cubic meters and cubic
centimeters. Write it in three forms.
I need help please someone let me know!!
Answer:
[tex]1\,\,m^3\,=\,10^6\,\,cm^3[/tex]
Step-by-step explanation:
To find: conversion factor between cubic meters and cubic centimeters
Solution:
One meter is 100 times greater than one centimeter .
1 meter = 100 centimeter
That is [tex]1\,\,m\,=\,100\,\,cm[/tex]
So,
[tex]1\,m^3\,=\,1000000\,cm^3[/tex]
or
[tex]1\,m^3\,=10^6\,cm^3[/tex]

Evaluate 32 + (8 − 2) ⋅ 4 − 6 over 3 . (1 point
Answer:
The answer would be 54 because you would follow the order of PEMDAS
you would do parentheses first which is 8-2 which is 6 then multiplication
so 6x4 = 24 then addition which is 32+24 which equals 56, then you would do 56-6/3 which would equal 54

The Schmidts brought a house 10 years ago and took out a mortgage. They are considering selling and want to know how much they still owe. They know their monthly payment and interest rate. Which of the following methods and correctly allow them to find the amount still owed?
Answer: a. They can find the present value of the remaining 20 years worth of payments.
Step-by-step explanation:
The present value of the payments for the servicing of the loan is the amount of the loan that is still owed because the payments include both the interest and the principal repayments.
The Schmidts can therefore find out the amount they still owe by checking the present value of the remaining 20 years worth of payments.
As the payments are usually constant they can be treated as an annuity so using the monthly payment as the annuity, the interest rate as the discount rate and the 20 years ( 240 months) as the period, they should be able to find the present value of the loan.

Express the interval using inequality notation.

Answer:
- 3 ≤ n ≤ 8
Step-by-step explanation:
Express the interval using inequality notation: -3,8
Interval between - 3 and 8, assumed both included, expressed as:
- 3 ≤ n ≤ 8Which of the following is true?a. The Z score for the median of a left skewed distribution is negative.b. Z scores are defined for observations from distributions of any shape and skew.c. The Z score for the median of a symmetric distribution is approximately 0.d. Calculating percentiles based on the Z table is only appropriate for observations that come from a nearly normal distribution.
Answer: b,c and d.
Step-by-step explanation:
The options that are true are:
b. Z scores are defined for observations from distributions of any shape and skew.
c. The Z score for the median of a symmetric distribution is approximately 0.
d. Calculating percentiles based on the Z table is only appropriate for observations that come from a nearly normal distribution.
It should be noted that option A"The Z score for the median of a left skewed distribution is negative" is false.
For a left skewed distribution, it should be noted that the mean is less than the median which in turn is less than the mode and this will bring about a positive outcome, therefore the corresponding z-score for the median will also be positive and bit negative.
Therefore, b, c and d are true.
If the z-score for the median of the left-skewed distribution is negative then A is false. Then the correct option is B, C, and D.
What is a z-score?The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
It should be noted that in option A, the z-score for the median of the left-skewed distribution is negative.
A. The Z-score for the median of a left-skewed distribution is negative. This is false.
B. Z-scores are defined for observations from distributions of any shape and skew. This is true.
C. The Z-score for the median of a symmetric distribution is approximately 0. This is true.
D. Calculating percentiles based on the Z-table is only appropriate for observations that come from a nearly normal distribution. This is true.

Standing from the top of a platform. Frank
shot an arrow vertically into the air at an
initial velocity of 118 ft/s. The height of the
arrow, h, at t seconds is modeled by the equation h = -16t^2 + 118t + 15. How many seconds will take the arrow to reach the
ground?
Answer:
7.5 seconds.
Step-by-step explanation:
The height of the arrow as a function of time t is given by :
[tex]h = -16t^2 + 118t + 15[/tex]
Here, 118 ft/s is the initial velocity and 15 feet is the height of the platform. We need to find How many seconds will take the arrow to reach the ground. When it reaches the ground, h(t) = 0
[tex]-16t^2 + 118t + 15=0[/tex]
The above is a quadratic equation. The solution of the above equation is given by :
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]
Here, b = 118, a = -16 and c = 15
So,
[tex]t=\dfrac{-118\pm \sqrt{(118)^2-4(-16)(15)} }{2\times (-16)}\\\\t=-0.125\ \text{and}\ 7.5\ s[/tex]
Time can't be negative.
So, it will take 7.5 seconds to reach the ground.

For the directed line segment whose endpoints are B(0, 0) and C(12, 24), find the point whose coordinates are 3/4 from B to C.
Answer:
(9, 18)
Step-by-step explanation:
If point P is 3/4 of the distance from B to C, it means that ...
BP/BC = 3/4
(P - B) = 3/4(C - B) . . . . . . multiply by BC = (C-B)
P = B + 3/4C -3/4B . . . . . add B
P = (1/4)B +(3/4)C = (B +3C)/4
P = ((0, 0) +3(12, 24))/4 = (36, 72)/4 = (9, 18)
The desired point is (9, 18).
__
As we showed, since B = (0, 0), the point is 3/4 of the coordinates of C.
The length of a rectangle is 3 units greater than its width. If the width is w, what expression gives the perimeter of the rectangle in terms of its width?
Step-by-step explanation:
let width be "w"
given,length of rectangle is 3 units greater than its width
length= w+ 3
perimeter of rectangle= 2( l+ b)
= 2[( w+3)+ w]
= 2(w to the power of 2 + 3w)
= 2w to the power of 2 + 6w
is the answer
The perimeter of the rectangle is 4w+6 units
What is the perimeter of rectangle?The perimeter of a rectangle is the sum of its four sides. Perimeter of Rectangle = 2 (Length + Width) units.
According to the question
Width of rectangle = w
Length of rectangle = w+3
Perimeter of Rectangle = 2 (Length + Width)
= 2( w+3 +w)
= 2(2w+3)
= 4w+6 units
Hence, The perimeter of the rectangle is 4w+6 units .

Dominic works on the weekends and on vacations from school mowing lawns in his neighborhood. For every lawn he mows, he charges $12. Complete the table. Then determine ordered pairs, and create a labeled graph. 1. How many lawns will Dominic need to mow in order to make $240? _________(blank 1) 2. How much money will he make if he mows 9 lawns? _________(blank 2) Question 1 options: Blank # 1 Blank # 2
Answer:
[tex]20\ lawns = \$240[/tex]
[tex]9 \ lawns = \$108[/tex]
See Attachment for Graph
Step-by-step explanation:
Given
[tex]1\ lawn = \$12[/tex]
Solving (a): Number of lawns in $240
[tex]1\ lawn = \$12[/tex]
Multiply both sides by 20
[tex]20 * 1\ lawn = \$12 * 20[/tex]
[tex]20\ lawns = \$240[/tex]
Solving (b): Cost of mowing 9 lawns
[tex]1\ lawn = \$12[/tex]
Multiply both sides by 9
[tex]9 * 1\ lawn = \$12 * 9[/tex]
[tex]9 \ lawns = \$108[/tex]
To create a graph, we need to generate a formula;
If
[tex]1\ lawn = \$12[/tex]
[tex]2\ lawn = \$24[/tex]
[tex]3\ lawns = \$36[/tex]
[tex]x\ lawns = \$12x[/tex]
So:
The graph formula is
[tex]y = 12x[/tex]
See Attachment for Graph
