Answer:

  C.  Residuals aren't random; linear is not a good fit

Step-by-step explanation:

The attached graph shows the given points (black) and the best-fit line (red). The residuals are connected by the dashed red line. They are decidedly NOT random. It appears that an exponential fit would work better than this linear fit.

The residual values are not randomly dispersed around the horizontal axis, so a linear fit is not appropriate.

Answer:

1026.02, you can round that online

Step-by-step explanation:

Considering the given discrete distribution, it is found that the probability that a randomly selected student earned a C or better is of 0.91.

It gives the probability of each grade, as follows:

Hence, the probability of a grade of C or better is given by:

[tex]P(X \geq C) = P(X = A) + P(X = B) + P(X = C) = 0.43 + 0.31 + 0.17 = 0.91[/tex]

Answer:

Area = 115 yards

Step-by-step explanation:

If we look at this as two rectangles, you can see that the area of one is going to be 10yd multiplied by 9yd, which gives us 90yd. The other smaller rectangle will be 6yd multiplied by 4yd, which gives us 24yd.

Now, add the two areas back together to get the area of the whole shape and you get A=115yd.

Step-by-step explanation:

Total number of people who play sports in the Algebra 2 class:

[tex]21 - 9 = 12[/tex]

If there are 10 students who play Basketball, there are 2 students who ONLY play Baseball. If there are 9 students who play Baseball, there are 3 students who ONLY play Basketball.

So the number of students who play BOTH sports is:

[tex]12 - 2 - 3 = 12 - 5 = 7[/tex]

If 7 from the 21 Algebra 2 class students play BOTH sports, the probability is:

Answer:

x = 4i - 1 or

x = 4i + 1

Step-by-step explanation:

(x+1)^2 = -4

x+1 = (+-)4i

x = +-4i - 1

x = 4i - 1 or

x = 4i + 1

Answer:

isosceles trapezoid

Step-by-step explanation:

1) find the distance of the points

[tex]\sqrt{(x2-x1)^2 + (y2 -y1)^2}[/tex]

AB = [tex]\sqrt{(4-2)^2 + (7-5)^2} = \sqrt{4 + 4} = \sqrt{8} = 2 \sqrt{2}[/tex]

BC = |7-4| = 3

CD = [tex]\sqrt{(9-7)^2 + (5-7)^2}= \sqrt{4+4} = \sqrt{8} = 2 \sqrt{2}[/tex]

AD = |9-2| = 7

2) equation of the line that passes threw BC

y = 7

3) equation of the line that passes threw AD

y = 5

conclusion

the quadrilateral has two parallel sides and two congruent sides, so it is a isosceles trapezoid

Profit in 2006:  $7 million

First convert the percent into decimal: 9% = 0.09

Then use the percent increase then multiply by the number using this formula: ( 1 + r ) = ( 1 + 0.09) = 1.09

You only want to find how much profit in 2006, so you do this:

2003: 5.4  

2004: 5.4 (1.09) = 5.886  

2005: 5.886 (1.09) = 6.41574  

2006: 6.41574 (1.09) = 6.99316

Then you take 6.99316 and round to the nearest tenth of a million dollars.

7 million dollars.

d x=+-3

Step-by-step explanation:

divide both sides by 2

Answer:

The last one.

Step-by-step explanation:

You can begin by dividing by - 2

-2*abs(x) =-6

-2*abs(x)/-2 = - 6/-2

abs(x) = 3

So x can be -3 or 3. Both are solutions

That's the last one.

Answer:

x = 38

∠P = 26º

Step-by-step explanation:

The sum of the angle in a triangle is 180

x + (x + 78) + (x - 12) = 180

Combine like terms

3x + 66 = 180

Subtract 66 from both sides

3x = 114

Divide both sides by 3

x = 38

-----------------------

∠P = x - 12

∠P = 38 - 12

∠P = 26º

Answer:

Step-by-step explanation:

(x+78)+(x-12)+x=180

3x+66=180

3x=114

x=38

P=26

1) find the total of candies

3 + 6 + 5 + 2 + 8 = 24

2) divide the number of yellow candies  for the total amount of candies

5/24 = 0.21 (correct)

3) use a proportion

6 : 24 = x : 200

x = (200 *6) / 24 = 50 (correct)

Answer:

m=3/4

Step-by-step explanation:

first, let's put the line 4x+3y=9 from standard form (ax+by=c) into slope-intercept form (y=mx+b)

we have the equation 4x+3y=9

subtract 4x from both sides

3y=-4x+9

divide by 3

y=-4/3x+3

perpendicular lines have slopes that are negative and reciprocal. If the slopes are multiplied together, the result is -1

so to find the slope of the line perpendicular to the line y=-4/3x+3, we can take the slope of y=-4/3x+3 (-4/3) multiply it by a variable (this is our unknown value), and have that set to -1

(m is the slope value)

-4/3m=-1

multiply by -3/4

m=3/4

therefore the slope of the perpendicular line is 3/4

Answer:

Miguel:

b = 2000 - 250m

Bartholomew:

b = 1500 - 150m

When m = 5

Step-by-step explanation:

Let

m = The number of months

b = balance on the credit card account in dollars.

Miguel owes $2000 and makes a monthly payments, reducing his debt by $250 per month.

Miguel:

b = 2000 - 250m

Bartholomew owes $1500 and makes monthly payments, reducing his debt by $150 per month

Bartholomew:

b = 1500 - 150m

When will Miguel and Bartholomew owe the same amount of money?

Miguel balance = Bartholomew balance

2000 - 250m = 1500 - 150m

2000 - 1500 = -150m + 250m

500 = 100m

m = 500/100

m = 5 months
