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
Angle A is x - 14

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.
Answers
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.

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
Answers
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
Dylan weighs 45 pounds. Use the expression you derived in part I to calculate how much more Bruce weighs than Alan.
Answers
Given: 1) weight of Dylan= 45 pounds
2) weight of Alan= 3 pounds more than twice the weight of Dylan
3)weight of Bruce = 12 pounds less than three times the weight of
Dylan.
To Find: How much more does Bruce weighs than Alan .
Solution:
weight of Dylan= 45 pounds
weight of Alan= 3 pounds more than twice the weight of Dylan
= 3 + ( 2×45) pounds
= (3+ 90) pounds
= 93 pounds
weight of Bruce= 12 pounds less than three times the weight of Dylan
= (3× 45) - 12 pounds
= (135) - 12 pounds
= 123 pounds
therefore, the amount by which Bruce weighs more than Alan will be given by:
weight of Bruce - weight of Alan
= 123 pounds - 93 pounds
= 30 pounds
Hence, Bruce weighs 30 pounds more than Alan.
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?
Answers
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.

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)

Devon earns a base salary of $600.00 per month, plus a 4% commission on his sales. Last month he brought in $15,000.00 in sales. Write an expression to represent his total compensation and calculate how much his total compensation was.
.4(600+s); $6,240
600+.04s; $1200
.04(600+s); $624
600+.4s; $6,600
Answers
Answer:
Total compensation = 600 + 0.04 * s and a total last month of $1200
(which agrees with the second answer shown in the provided list)
Step-by-step explanation:
Total compensation comes from the addition of base salary ($600) plus 4% (0.04) of the sales (s). That means:
Total compensation = 600 + 0.04 * s
and since last month he brought $15000 in sales, he got from sales:
0.04 * 15000 = $600
which added to the base salary gives:
$600 + $600 = $1200

What is slope?The slope is the rate of change of the y-axis with respect to the x-axis.
The equation of a line in slope-intercept form is y = mx + b, where
slope = m and y-intercept = b.
We know the greater the absolute value of a slope is the more steeper is it's graph or rate of change is large.
From the graph the two pair of points are (0, 6) and (8, 16).
So, slope(m) = (16 - 6)/(8 - 0).
slope(m) = 10/8.
slope(m) = 5/4.
slope(m) = 1.25.
So, The monthly subscription fee is $1.25.
Now, Cost of one video game can be obtained by equation y = mx + b.
6 = 1.25(0) + b.
b = 6, so the cost of per video game is $6.

| 5x + 10| = -7
Thank you!
Answers
Answer:
the equation | 5x + 10| = -7 has no solution for x ∈ R.
Step-by-step explanation:
Given the absolute value equation
| 5x + 10| = -7
We know that absolute value is always positive.Reason:
The reason is that the absolute value is the distance from the number 0. Hence, it can not be less than or equal to a negative number.
Conclusion:
Therefore, we conclude that the absolute value of any number would be either 0 or positive as it can not less than or equal to a negative number.
Therefore, the equation | 5x + 10| = -7 has NO SOLUTION for x ∈ R.

How many people preferred drinking water?
WHO EVER ANSWERS GETS MARK AS BRAINLIEST
Answers
Answer:
174 people preferred drinking water.
Step-by-step explanation:
Given that:
A total of 450 males and females were surveyed.
203 were males.
Number of females = 450 - 203 = 247 females
247 females were surveyed.
Now, we will find the number of females who prefer water.
Let,
x be that number.
Total number of females = Soda + Iced tea + Lemonade + Water
247 = 28 + 44 + 67 + x
247 = 139 + x
247-139 = x
x = 108
Number of people who prefer water = 108 + 66 = 174
Hence,
174 people preferred drinking water.

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?
Answers
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
