  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.

Step-by-step explanation:

if the parent function, y=f(x) has a number added (y=f(x)+4) the graph will be translated up. If the parent function has a number subtracted, y=f(x)-4, the graph will be translated down. The image explains more simply, and there are more possible translations (shown in image)

Answer:

10 m building in Patrick's drawing would be of  0.5 cm

Step-by-step explanation:

Scale of Patrick's drawing is

1 inch = 10 meters

or 2.54 cm = 10 meters

1 cm = 3.94 m

In case of  Squidward the scale is 2 cm = 40 meters or

1 cm = 20 meters

So a 10 m building in Patrick's drawing would be of

0.5 cm

Answer:

13.5

Step-by-step explanation:  

Given: Patrick’s drawing uses a scale of 1 inch = 10 meters. Squidward made another scale drawing of the hotel with a scale of 2 cm = 40 meters.  

To find: How tall is the hotel on Squidward’s drawing?  

Formula: Height of the building = y × tan x + measurer's height  

Solution: The height of the building is calculated by using the formula. y = distance of the measurer from the building. x = the angle measured from the clinometer.

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:

Step-by-step explanation:

The distance R from A and the bearing of R from A​ 15 km and 189° respectively.

The law of sine or the sine law states that the ratio of the side length of a triangle to the sine of the opposite angle, which is the same for all three sides.

The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them.

Given that, a village R is 10 km from a point P on a bearing 25° from P. Another village A is 6 km from P on a bearing 162°.

We need to calculate, the distance R from A and the bearing of R from A​

We will use the Cosine Rule to determine the distance of R from A (p);

From Cosine Rule;

b² = a² + c²– 2ac Cos B

p² = a² + r² – 2ar Cos P

a= 10 km

Cos P = Cos 137

r = 6 km

p = ?

p² = a² + r² – 2ar Cos P

p² = 10² + 6² - 2 (10) (6) Cos 1370

p² = 100 + 36 – 120 (- 0.7314)

p² = 136 + 87.76

p² = 223.76

p = 14.95 = 15 km (approximated to the nearest km)

To find the bearing of the R from A,

we will apply Sine Rule;

From Sine Rule;

15Sin Ø = 10Sin 137 = 6.82

Sin Ø = 6.82/15 = 0.4547

Ø = ArcSin 0.4547 = 27°

Therefore, the bearing of R from A will be

∠ PRA = 180 – 137 – 27 = 160

The alternating angle to 25° at R is 65°

Then, the bearing of R from A = 270 -65-16 = 189°

Hence, the distance R from A and the bearing of R from A​ 15 km and 189° respectively.

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

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

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.
