Step-by-step explanation:
7)Let's solve your equation step-by-step.
4x+34=8−9x
Step 1: Simplify both sides of the equation.
4x+34=8−9x
4x+34=8+−9x
4x+34=−9x+8
Step 2: Add 9x to both sides.
4x+34+9x=−9x+8+9x
13x+34=8
Step 3: Subtract 34 from both sides.
13x+34−34=8−34
13x=−26
Step 4: Divide both sides by 13.

11) Let's solve your equation step-by-step.
2x−18=−9−x
Step 1: Simplify both sides of the equation.
2x−18=−9−x
2x+−18=−9+−x
2x−18=−x−9
Step 2: Add x to both sides.
2x−18+x=−x−9+x
3x−18=−9
Step 3: Add 18 to both sides.
3x−18+18=−9+18
3x=9
Step 4: Divide both sides by 3.
Answer:
x=3
8) Let's solve your equation step-by-step.
−x−7=3x−7
Step 1: Subtract 3x from both sides.
−x−7−3x=3x−7−3x
−4x−7=−7
Step 2: Add 7 to both sides.
−4x−7+7=−7+7
−4x=0
Step 3: Divide both sides by -4.
−4x /-4=0 /-4
x=0

x=3/4=0.750
We move all terms to the left:
x-(3/4)=0
We add all the numbers together, and all the variables
x-(+3/4)=0
We get rid of parentheses
x-3/4=0
We multiply all the terms by the denominator
x*4-3=0
Wy multiply elements
4x-3=0
We move all terms containing x to the left, all other terms to the right
4x=3
x=3/4

A production process produces 5% defective parts. A sample of five parts from the production process is selected. What is the probability that the sample contains exactly two defective parts
Answers
Answer:
0.0214
Step-by-step explanation:
Given that :
p = 5% = 0.05
Number of trials (n) = 5
probability that the sample contains exactly two defective parts
P(x = 2)
Using the binomial probability function :
P(x = x) = nCr * p^x * (1 - p)^(n-x)
P(x = 2) = 5C2 * 0.05^2 * (0.95)^3
P(x = 2) = 5C2 * 0.05^2 * (0.95)^3
P(x = 2) = 10 * 0.0025 * 0.857375
= 0.021434375
= 0.0214

If we find that the null hypothesis, Upper H Subscript 0 Baseline colon beta Subscript j Baseline equals 0, cannot be rejected when testing the contribution of an individual regressor variable to the model, we usually should:___________
Answers
Answer:
Remove the variable from the Model
Step-by-step explanation:
Normally, when considering which variable to keep and which one to drop when considering testing of the contribution of an individual regressor variable to the model, generally speaking we use one explanatory variable for between 10-15 observations.
Now, before we run our regression, we would need to run correlation analysis between all explanatory variables to detect if there's any multicollinearity, and also between the dependent variable and the regressors in order to determine the most important predictors to be included in the regression.
So after the analysis, for the null hypothesis not to be rejected, we will remove the variable from the Model.

one room length 12.8 and breadth equals to 850 CM inside that room there is a bad length is 300 cm and breadth is 400 cm find the remaining surface area of the room and the answer will be in cm
Answers
Answer:
[tex]Area = 968000cm^2[/tex]
Step-by-step explanation:
To be able to answer this question properly. I'll assume the length of the room is in meters.
So for the room, we have:
[tex]Length = 12.8m[/tex]
[tex]Breadth = 850cm[/tex]
For the bed, we have:
[tex]Length = 300cm[/tex]
[tex]Breadth = 400cm[/tex]
First, we calculate the surface area of the room.
[tex]A_1 = 12.8m * 850cm[/tex]
Convert all units to cm
[tex]A_1= 12.8*100cm * 850cm[/tex]
[tex]A_1= 1 088 000 cm^2[/tex]
Next, we calculate the area of the bed
[tex]A_2 = 300cm * 400cm[/tex]
[tex]A_2 = 120000cm^2[/tex]
The area of the space left is the difference between A1 and A2
[tex]Area = A_1 - A_2[/tex]
[tex]Area = 1088000cm^2 - 120000cm^2[/tex]
[tex]Area = 968000cm^2[/tex]

Step-by-step explanation:
Answer:
The correct answer is graph C.
Step-by-step explanation:
❌On a coordinate plane, a line goes through points (negative 3, 0) and (0, negative 3).
- the first point needs to be swapped in order to form x-3.
❌On a coordinate plane, a line goes through points (0, negative 1) and (1, 2).
- doesnt have a negative 3.
✔On a coordinate plane, a line goes through points (0, negative 3) and (3, 0).

The correct answer is shownfind the slope of the line from the values in the table. Explain your steps.
Answers
Answer:
3
Step-by-step explanation:
Using any two pairs from the table if values, say, (5, 16) and (7, 22), the slope of the line is the change in y over change in x.
Thus:
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let,
[tex] (5, 16) = (x_1, y_1) [/tex]
[tex] (7, 22) = (x_2, y_2) [/tex]
Plug in the values
[tex] slope (m) = \frac{22 - 16}{7 - 5} = \frac{6}{2} = 3 [/tex].
Slope of the line is 3.

Answers
Answer:
r=144
Step-by-step explanation:
Cross multiply:
12 * 60 = r * 5
Simplifying
12 * 60 = r * 5
Multiply 12 * 60
720 = r * 5
Reorder the terms for easier multiplication:
720 = 5r
Solving
720 = 5r
Solving for variable 'r'.
Move all terms containing r to the left, all other terms to the right.
Add '-5r' to each side of the equation.
720 + -5r = 5r + -5r
Combine like terms: 5r + -5r = 0
720 + -5r = 0
Add '-720' to each side of the equation.
720 + -720 + -5r = 0 + -720
Combine like terms: 720 + -720 = 0
0 + -5r = 0 + -720
-5r = 0 + -720
Combine like terms: 0 + -720 = -720
-5r = -720
Divide each side by '-5'.
r = 144
Simplifying
r = 144
Answer:
r=144
Step-by-step explanation:
We need to find r. To do that me must make the top numbers the same.
We'll multiply
[tex] \frac{12}{r} \times \frac{5}{5 } = \frac{60}{5r} [/tex]
[tex] \frac{5}{60} \times \frac{12}{12} = \frac{60}{720} [/tex]
Since the top numbers are equal that means the bottoms are too.
So we can create the equation:
[tex]5r = 720[/tex]
Divide each side by 5
r=144
Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

Find the diagonal of the box using the Pythagorean Theorem.
PLS HELP ASAP 50 POINTS PLEASE HELP ASAP PLEASEEE!!!! I NEED HELP ASAP
(Image Linked)
Answers
Answer:
26 cm
Step-by-step explanation:
Diagonal of the box using Pythagorean Theorem can be calculated using the formula:
a² + b² + c² = d²
Where,
d = diagonal of the box = ??
a = length = 24 cm
b = width = 8 cm
c = height = 6 cm
Plug in the value into the formula
24² + 8² + 6² = d²
576 + 64 + 36 = d²
676 = d²
√676 = d
d = 26 cm
