Find the Average Rate of Change between the values of [0, 1]
Answer:
The average rate of change cover the given interval is -6
Step-by-step explanation:
The average rate of change of a function over a range can be calculated by;
f(b) - f(a)/b-a
f(b) and f(a) refers to the respective y values of the x values a and b
Since we have a and b, we can get f(a) and f(b) from the plot
From the graph, since a = 0, f(a) is the y-intercept = 6
b = 1
f(b) = 0
So we have the slope as
= (0-6)/(1-0) = -6/1 = -6

Answer:
y=1/4x-1
Step-by-step explanation:
So lets start off by going over what slope intecerp form is.
Slope intercept form looks like this:
y=mx+b
Lets go over the different values in this formula:
y is always going to just be what mx+b equals, and you can plug in values for x to solve for it.
m is always teh slope. The slope is y/x, basically just the change in y over the change in x.
x is going to be the number you plug in a value for to solve for y.When writing slope intercept form, this will always just be x.
Lastly we have b. This is what y equals when x is 0.
Lets use this to make our slope intercept.
So we have:
y=mx+b
y and x are not going to have a written value, so we only need to determine m and b.
So lets find b.
B will be the slope. When we look at the points on the graph, we see (-4, -2) and (0, -1)
The difference in y is -1.(-2--1=-1). The difference in the x is -4.(-4-0=-4).
So b will be: -1/-4, or just 1/4:
y=1/4x+b
Now lets find b.
Lets specificly lookat what y equals when x is 0 on the graph.
We can see the point is (0, -1)
So the y intercept is -1. This means b is equal to -1:
y=1/4x-1
This is your slope intercept!
Hope this helps! :D

Juan bought 5 cupcakes and 3 bearclaws for 45$. Lily bought 4 of the same cupcakes and 6 of the same bearclaws for 72$. What is the price of each item?
Answer:
Cup cakes= $3
Bear claws = $10
Step-by-step explanation:
Let the orice of cupcakes be x and the price of bear claws be y
5x+ 3y= 45
4x + 6y= 72
Multiply equation 1 by 4 and equation 2 by 5
20x + 12y= 180
20x + 30y= 360
-18y= -180
y= 10
Substitute 10 for y in equation 1
5x + 3(10)= 45
5x + 30= 45
5x = 45-30
5x= 15
x= 15/5
= 3
Hence the price of cup cakes is 3 and bear claws is $10
3x-y=-5
5x+7y=29
Solve this for me using substitution pls

A 98% confidence interval for a proportion is found to be (0.47, 0.53). What is
the sample proportion?
A. 0.53
B. 0.51
C. 0.49
D. 0.50
Answer:
0.50
Step-by-step explanation:
The sample proportion to be found for 98% confidence interval is
D. 0.50.
What is a confidence interval?The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval.
Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test.
In statistics, confidence is another word for probability.
Given, Sample = (0.47, 0.53).
Confidence interval = 98%.
Therefore, The sample proportion is,
= (0.47 + 0.53)/2.
= 1/2.
= 0.5.
So, The sample proportion is 0.50.

Find the area of the following colored regions?
Answer:
Area = 77.1
Step-by-step explanation:
The are of a right triangle is
[tex] \frac{1}{2} \times base \times height[/tex]
our base and height are 6 for both triangles, so we shall find the area of one of the triangles...
[tex] \frac{1}{2} \times 6 \times 6 = 18[/tex]
multiply this by 2
[tex]2 \times 18 = 36[/tex]
Now find the area of the whole circle
[tex]area = \pi {r}^{2} [/tex]
our radius is 6, therefore:
[tex]area = \pi {6}^{2} = 113.1[/tex]
Finally, subtract the area of the two triangles from the total are of the circle. The difference left over is our answer
[tex]113.1 - 36 = 77.1[/tex]
Answer:
Exact Area = 36pi - 36 square meters
Approximate Area = 77.04 square meters (when using pi = 3.14)
================================================
Explanation:
The circle has radius r = 6 meters. The area of the circle is...
A = pi*r^2
A = pi*6^2
A = 36pi
This is the exact area in terms of pi.
Because we have two right triangles, and each right triangle has the same leg length, we can effectively use the SAS theorem to prove the triangles are congruent. Therefore, both of the triangles shown have the same area. One triangle is a rotated copy of the other.
The area of one of the triangles is base*height/2 = 6*6/2 = 18 square meters. That means two of them combine to an area of 18*2 = 36 square meters.
Subtract this from the area of the circle to get the green shaded area
green area = (circle area) - (triangle areas)
green area = (36pi) - (36)
green area = 36pi - 36
This is the exact area in terms of pi. If you want the approximate area, then replace pi with its approximate value. Let's say we go for pi = 3.14
That means,
green area = 36pi - 36
green area = 36*3.14 - 36
green area = 77.04 square meters approximately
Use more decimal digits in pi to get a more accurate area value.

10 meters apart, how high up is Roy? If necessary, round to the nearest tenth.
_____ meters
Please and thank you!
No links!!!!
Answer:
7.1 meters
Step-by-step explanation:
Use the pythagorean theory:
10 would be the hypotenuse
7 would be one of the legs
and x (or whatever variable you'd like) would be the other leg.
7^2+x^2=10^2
49+x^2=100
subtract 49 from both sides
x^2=51
take the square root on both sides
x is approximately 7.1
There are 10 10 balls total of which 2 2 balls are purple. Leslie picks a ball at random, puts it back and picks a second ball at random. Find the probability of first picking a purple ball and then again a purple ball on the second draw.
Answer: 1/25
Step-by-step explanation:
Number of balls = 10
Number of purple balls = 2
Since it's probability with replacement,
Probability of picking a purple ball the first time = 2/10 = 1/5
Probability of picking a purple ball the second time = 2/10 = 1/5
Therefore, the probability of picking a purple ball both times will be:
= 1/5 × 1/5
= 1/25

how do I solve this please help!
Answer:
9 x + 8 y = 10 (I)
y = -4x + 7 (II)
One way is to rewrite the second as
4x + y = 7
Now multiply this equation by 8
32 x + 8 y = 56
9 x + 8 y = 10 and now subtract the equations
23 x = 46 this gives x as 2
From equation (II) y = -4 (2) + 7 = -1
So our values are (2, -1)
Check:
(I) 9 x + 8 y = 10 9 * 2 - 8 = 10
(II) 4 x + y = 7 or 4 * 2 - 1 = 7
Or you can substitute equation (II) directly into equation (I)
