Answer:
Step-by-step explanation:
Important things to note:
- The 5 and 3 are multiplied together because they are both regular numbers
- The 
and 
are multiplied together because they are they same variable
- When multiplying values with exponents, the exponents are added together

Answer:
Solution of the equations is (1, -2).
Step-by-step explanation:
Two linear equations given in the question are
y = -3x+1-------------(1)
and y = 2x-4 ------------(2)
To solve these equations by substitution method we will substitute the value of y from equation (1) to equation number (2).
-3x+1 = 2x-4
Now we add 3x on both the sides of the equation
3x-3x+1 = 3x+2x-4
1 = 5x-4
we will add 4 on both the sides
1+4 = 5x-4+4
5 = 5x
Then we divide the equation by 5
5/5 = 5x/5
x = 5/5 = 1
Now we solve the equation (1) for the value of y by putting x = 1
y = -3(1)+1 = -3+1 = (-2)
So the solution will be (1 -2).
Total frequency = 56.
Total fx = 1717
midpoint of 45-49 = 47
Mean of the data = 30.7
Median of the data = 31.3
Mode of the data = 32.5
<h3>What is Mean?</h3>
A measure of central tendency (also referred to as measures of centre or central location) is a summary measure that attempts to describe a whole set of data with a single value that represents the middle or centre of its distribution.
Here, total frequency ∑f = 5+7+9+11+8+7+5+4
= 56 (option B)
Total fx or ∑fx = 12X4 + 17X5 + 22X7 + 27X8 + 32X11 + 37X9 + 42X7+ 47X5
= 48 + 85 + 154 + 216 + 352 + 333 + 294 + 235
= 1717 (option B)
The midpoint of the score 45-49 = (45 + 49)/2
= 47 (option B)
Mean of the data = ∑fx/ ∑f
= 1717 / 56
= 30.7 (option D)
Median of the data = 31.3 (option A)
Mode of the data = 32.5 (option B)
Thus, Total frequency = 56.
Total fx = 1717
midpoint of 45-49 = 47
Mean of the data = 30.7
Median of the data = 31.3
Mode of the data = 32.5

I can’t answer anything from my side so I will guide you the best I can! Measure the highlighted lines on the image. Then record the numbers into the correct areas(length,width,height). Then multiply all of the numbers above. That’s how you answer question 3. I’m sorry that I can’t do much more on my side.
