The graph shows a proportional relationship between the c cups of
flour used and the number of m muffins baked.
Identify the constant of proportionality from the graph. (The picture is the second part to the question)

A) 1
B) 2
C) 4
D) 8

Answer:

84

Step-by-step explanation:

8x6=48

2x4=8

4x7=28

48+28+8=84

Answer:

1. Equation: y = -1.17491x + 81.791 (you may need to round!)

2. Correlation coefficient: -0.8566

3. Strong negative correlation because the correlation coefficient is close to -1

4. Sketch the scatterplot using north latitude as the x value and Jan mean temp as the y value on the graph

Step-by-step explanation:

Step 1: Go to desmos graphing calculator

Step 2: Insert a table

Step 3: Insert values into the table (shown in image) using the north latitude as the x value and jan mean temp as y value

Step 4: Go to line 2, and type "[tex]y_1 = mx_1 + b[/tex]" except replace "=" with ~ as shown in the image. Put the 1s as subscripts

Step 5: Scroll out. Desmos would've graphed the line of best fit and plotted the points. Under statistics, you can see that r is the correlation coefficient

Step 6: The correlation coefficient r will be between -1 and 1. If it is closer to -1 or 1, it is a strong correlation. If it is closer to 0, it is a weak correlation. For example. -0.6 is closer to -1 than it is to 0, so it is a strong negative correlation. You can see that r here is -0.8566, which is strong negative.

Step 7: Lastly, you need to make the equation. It will be in the form y = mx + b. If you look under "parameters", there will be a value for m and b. Plug that in to the equation. Check to see if you need to round.

Step 8: To graph the scatterplots, you can use the graph and the points that desmos plotted as a reference. Good luck!

I hope I did it right, we just finished this at school and I got 100% on the test. Comment with any questions. Best of luck! - brainpop72

Answer:according to the formula of inscribed angle theorem

[tex]3x + 22 = \frac{1}{2 } \times 134[/tex]

[tex]3x + 22 = 67[/tex]

[tex]3x = 67 - 22[/tex]

[tex]3x = 45[/tex]

[tex]x = \frac{45}{3} [/tex]

[tex]x = 15[/tex]

The answer is 15 degrees

Answer:

b= 10 miles/hr and c= 5 miles/hr

Step-by-step explanation:

Let it's downstream and upstream speed be d and u respectively

also speed of the boat be b and speed of stream be c.

as per question d = 150/10= 15 miles/hr

and, u= 150/30= 5 miles/hr

also we know d= b+c = 15.....i and u = b-c= 5....ii

solving i and ii we get b= 10 miles/hr and c= 5 miles/hr

Answer:

It's the last one where x=3 and y=2

Explanation:

Replace x and y with 3 and 2. It then becomes

-4(3) + 8(2) = 4

Solve. -4 × 3 is -12 since a positive times a negative equals a negative. 8 × 2 is 16. Bring down the 4.

-12 + 16 = 4

When solving something like this and you don't know what to do or how to solve it, you can subtract the smaller number from the larger number and then whether the sum is a negative or positive depends on the largest number. So here, 16 is the largest, so the sum will be positive. And 16-12 is 4, so the final answer is positive 4. You can also look at a number line and start from -12 and then add 16 and see which number you end at after adding 16.

Step-by-step explanation:

Step 1: Define

Point (-8, -6)

Point (-3, -2)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Answer:

6.4

Step-by-step explanation:

d=√((−3−(−8))^2+(−2−(−6))^2)

d=√((5)^2+(4)^2)

d=√(25+16)

d=√(41)

d=6.403124

d=6.4

Answer: A = 317

B = 61

Step-by-step explanation:

The following equation can be gotten from the question given. This will be:

A + B = 379 ........ i

A - B = 255 ........ ii

From equation i, make A the subject of the formula

A = 379 - B ...... iii

Put the value of A in iii into equation ii

A - B = 255

(379 - B) - B = 255

379 - B - B = 255

379 - 2B = 255

2B = 379-255

2B = 124

B = 124/2

B = 62 tons

Since A + B = 379

A + 62 = 379

A = 379 - 62

A = 317 tons

Answer:

16 years

Step-by-step explanation:

Principal amount (P) = $600

Rate of interest (R) = 2.75%

Simple interest (S.I.) = $264

Let t denotes time period.

[tex]S.I.=\frac{PRT}{100}[/tex]

[tex]264=\frac{600(2.75)t}{100} \\\\t=\frac{264(100)}{600(2.75)}[/tex]

[tex]t=16[/tex] years.  

Therefore,

interest of $264 will be earned in 16 years.

Answer:

We know that Silvia has $5.50 in her piggy bank, and she earns $2 per chore she does at her house.

So if she does x chores at her house, she will have:

y = f(x) = $2*x + $5.50

where y = her savings.

This is a linear relationship, to graph this, we need to evaluate the function in two different values of x so we can get two ordered pairs.

Then we graph the ordered pairs in the coordinate axis, and then we draw a line that passes through both points.

We can use the points given by x = 0.

y = f(0) = $2*0 + $5.50 = $5.50

Then we have the point (0, $5.50)

and if we use x = 1 we get:

y = f(1) = $2*1 + $5.50 = $7.50

Then we have the point (1, $7.50)

Now we just need to graph the points (0, $5.50) and (1, $7.50), and draw a line that passes through them.

The graph is shown below.
