Answer/Step-by-step explanation:
Rearrange terms8 − 5 = 2 + 2 0 − 5 + 8 = 2 + 2 0
Subtract 8 from both sides of the equation − 5 + 8 = 2 + 2 0 − 5 + 8 − 8 = 2 + 2 0 − 8SimplifySubtract the numbers− 5 = 2 + 1 2
Subtract 2 2x 2x from both sides of the equation − 5 = 2 + 1 2 − 5 − 2 = 2 + 1 2 − 2xSimplify Combine like terms− 7 = 1 2
Divide both sides of the equation by the same term− 7 = 1 2 − 7 − 7 = 1 2 − 7
Simplify Cancel terms that are in both the numerator and denominator Divide the numbers= − 1 2 7

Step-by-step explanation:
Using the equation ŷ = 2.6 − 3.1x, what is the predicted value if x is 4.3?
Select one:
a. −10.73
b. 10.73
c. 15.93
d. −15.93
e. 0.54
Work Shown:
Plug x = 4.3 into the equation given
ŷ = 2.6 − 3.1x
ŷ = 2.6 − 3.1(4.3)
ŷ = 2.6 − 13.33
ŷ = -10.73
Note: The symbol ŷ is read as "y hat". It's used to estimate the y value when it comes to regression equations.
-2n divided by 3 + (4n - n), when n = 6
Step-by-step explanation:
Divisor = -2n = -2 * 6 = - 12
Dividend = 3 + ( 4 * 6 - 6) = 3 + 18 = 21
Now
21 / -12
dividing numerator and denominator by 3
= - 7 / 4
Step-by-step explanation:
= -2n
= -2×6
= -12
again,
=3+(4n-n)
= 3+4×6-6
=3+24-6
=21
now,
= -12

If Y varies directly with X,
find Y when X=24, if Y = 5
when X= 30.
Answer:
Y=4 when X =24
Step-by-step explanation:
If Y varies directly with X, find Y when X=24, if Y = 5 when X= 30.
We can write:
[tex]Y\:\alpha\: X\\Y=kX[/tex]
Where k is known as constant of proportionality
Now, we are given: Y = 5 when X= 30.
We can find value of k
[tex]Y=kX\\5=k(30)\\k=\frac{5}{30}\\k=\frac{1}{6}[/tex]
Now, we will find Y when X = 24
and k=1/6
[tex]Y=kX\\Y=\frac{1}{6}(24)\\Y=4[/tex]
So, Y=4 when X =24.

Answer:
y + 3 = -½(x - 1)
Step-by-step explanation:
Point-slope form equation is given as y - b = m(x - a), where,
m = slope, and (a, b) is a point the line passes through.
Given that the line is perpendicular to the y = 2x - 1, the slope (m) will be the negative reciprocal of 2, which is -½.
Thus, substitute m = -½, a = 1, and b = -3 into y - b = m(x - a).
Thus:
y - (-3) = -½(x - 1)
y + 3 = -½(x - 1)

Answer:
76˚
Step-by-step explanation:
All angles of a triangle total up to 180˚ so we can make this equation:
x - 14 + 1/2x + 7 + 2x - 128 = 180
3.5x - 135 = 180
3.5x = 315
x = 90

Two trains leave the station at the same time, one heading west and the other east. The westbound train travels at 75 miles per hour. The eastbound train
travels at 85 miles per hour. How long will it take for the two trains to be 256 miles apart?
Answer:
1.6 hours
Step-by-step explanation:
The two trains will be (75+85)=160 miles apart after each hour.
Therefore the time taken for the trains to be 256 miles apart would be 256/160 hours = 1.6 hours.
f=2(3-5g) make g the subject
Answer:
The function 'f' in terms of 'g'
[tex]g = \frac{3}{5}-\frac{f}{10}[/tex]
Step-by-step explanation:
Explanation:-
Given function f = 2 (3-5g)
f = 6 - 10 g
10g = 6 - f
⇒ [tex]g = \frac{6-f}{10}[/tex]
[tex]g = \frac{6}{10}-\frac{f}{10}[/tex]
[tex]g = \frac{3}{5}-\frac{f}{10}[/tex]
jesse bought a car for 2,200,000 he sold for a 20% profit from the money raised from the sale he bought another more expensive car which unfortunately he had to sell for a 10% loss that was his overall profit or loss
Answer:1,76,000 Profit
Step-by-step explanation:
Given
Jesse initially bought the car for 2,200,000 and sold it for 20 %
S.P.=C.P.(1+Profit%)
so, the Selling price of the car is S.P.=[tex]2,200,000\times 1.2=2,640,000[/tex]
profit=2,640,000-2,200,000=4,40,000
After this, he bought another car and sells it for a 10 % loss
So, the selling price of the car is [tex]2,640,000\times 0.9=2,376,000[/tex]
loss=2,640,000-2,376,000=2,64,000
Net Profit or loss=4,40,000-2,64,000=1,76,000 Profit

The population of Kenya was 45.1 million in 2009 and has been growing by 2.3% each year. If this trend continues, in what year will the population exceed 52.2 million?
Answer:
the year is 2016
Step-by-step explanation:
The computation is shown below:
Given that
The population in 2009 is 45.1 million
And it would be increased 2.3% each year
So,
In the year 2010 it is = 45.1 million × (1 + 0.023) = $46.14 million
In the year 2011, it is = $46.14 million × (1 + 0.023) =$47.20 million
In the year 2012, it is = $47.20 million × (1 + 0.023) = $48.29 million
In the year 2013, it is = $48.29 million × (1 + 0.023) = $49.40 million
In the year 2014, it is = $49.40 million × (1 + 0.023) = $50.54 million
In the year 2015, it is = $50.54 million × (1 + 0.023) = $51.70 million
In the year 2016, it is = $51.70 million × (1 + 0.023) = $52.89 million
Hence, the year is 2016

y = -2x - 9
6x - 5y = -19
Hey there!
y = -2x - 9
6x - 5y = -19
We're going to label the first equation as "1" and the second equation as "2." Now, in order to find the values of "x" & "y," we need to even out the equations by placing their "x" and "y" markers on the same side of the equal sign.
Let's start off by adding 2x to both sides of equation 1.
1) y + 2x = -2x - 9 + 2x
Simplify.
Equation 1 is now: 2x + y = -9
Now, we need to multiply equation 1 equations by "3" in order to create "6x" in both equations. This helps us find the value of "y" because it cancels out the "x" in both equations.
1) (2x + y = -9) × 3
Simplify.
1) 6x + 3y = -27
2) 6x - 5y = -19
Now that our equations are lined up, we can subtract equation 2 from equation 1.
6x - 6x = 03y - (-5y) = 3y + 5y = 8y-27 -(-19) = -27 + 19 = -8Let's put this all together now.
8y = -8
Divide both sides by 8!
8y ÷ 8 = -8 ÷ 8
Simplify.
y = -1Now that we have the value of y, we can easily plug it into one of our equations to get our "x" value.
Equation 1: y = -2x - 9
Plug in "-1" for "y."
-1 = -2x - 9
Add 9 to both sides
-1 + 9 = -2x - 9 + 9
Simplify.
8 = -2x
Divide both sides by -2.
8 ÷ -2 = -2x ÷ -2
Simplify.
-4 = xTherefore, x = -4 & y = -1
(-4, -1)Hope this helped! :)
Answer:
x = - 4
y = - 1
Step-by-step explanation:
y = -2x - 9
2x + y = - 92x + y = -9 (× 3)
6x - 5y = -19
______________
Elimination
6x + 3y = - 27
6x - 5y = - 19
____________ _
8y = - 8y = - 8/8y = -1Solution for x :
Substitution
6x - 5y = -19
6x - 5(-1) = -19
6x + 5 = - 19
6x = - 19 - 5
6x = - 24
x = -24/6
x = -46x - 5y = - 19
6(-4) - 5(-1) = - 19
-24 + 5 = - 19
-19 = - 19

1. Based on data collected over several sessions, a statistically minded trainer of office typists modeled the linzoom in
between the number of hours of training a typist receives and the typist's speed (in words per minute) with the equauon
speed = 10.3 +5.4(hour). After some training, one of the typists was told that the speed he attained had a residual of 4.2
words per minute. How should he interpret this?
Choose the correct answer below.
1
A. He cannot interpret his residual without also knowing the correlation.
B. He cannot interpret his residual without also knowing the size of other people's residuals.
C. He types slower than the model predicted, given the amount of time he spent training.
D. He types faster than the model predicted, given the amount of time he spent training.
Answer:
Statement D is correct.
Step-by-step explanation:
Solution:
Data Given:
Linear Regression Relationship = Speed = 10.3 + 5.4 (hour)
Linear Regression Relationship = y = mx + c
Here,
m = slope = 5.4
c = 10.3 = y - intercept
The correct Answer is D)
Because:
As, the residual value is positive, it means the typist attained faster speed than the model predicted. As we know, residuals is the result of difference between predicted values of the model and data values. On the contrary, if residual would be negative then we would say that typist speed is slower than the model predicted.
Hence, Statement D is correct.
