Step-by-step explanation:
so, we had
4+3+2+2+6 = 17 experiments
I assume the spinner has 5 equality sized fields with different colors.
so, normally we would assume that in average each color has the same probability : 1/5 (desired results over totally possible results).
the experiments with the actual spinner give us now observational data and probabilities.
after all, a spinner (as a die, or a roulette wheel, or ...) can have slightly different probabilities for the individual outcomes based on design and manufacturing.
so, based on these results we see the actual probabilities like this
red 4/17
blue 3/17
green 2/17
yellow 2/17
purple 6/17
so, the observed probability shows us a probability of blue in the next spin to be 3/17.
please note, that after that next (18th) spin all the observed probabilities have to be updated depending on the actual result.
so, if the result of spin 18 is indeed blue, the probabilities for spin 19 would change to
red 4/18
blue 4/18
green 2/18
yellow 2/18
purple 6/18
Can someone please help me with this? I just need to know how it works and what the answer is.
Answer:
3
Step-by-step explanation:
Since you need to find the y value when x = -1, go to -1 on the x axis, and find where the green line crosses. The green line goes through the point (-1,3), or one box to the left and three boxes up, so the y value is 3.
Hopefully this helps- let me know if you have any questions!
Answer:Find the point in which the x = 1, and the y point meets.
When x = 1, y = 2
2 is your answer for y

The areas of the two rectangles below are equal. There are two possible areas. One is 105 u2
What is the other one?
Answer:
144 u²
Step-by-step explanation:
⇒ Areas are equal
(6x + 15)(2x + 7) = (4x + 7)(2x + 15)12x² + 42x + 30x + 105 = 8x² + 60x + 14x + 1054x² = 2xx = 1/2Calculating the areas
(6 x 1/2 + 15)(2 x 1/2 + 7) = 18 x 8 = 144(4 x 1/2 + 7)(2 x 1/2 + 15) = 9 x 16 = 144The other one is 144 u²

Answer:
d. -2 <= y <= infinity
Step-by-step explanation:
The graph starts at -2 with a solid (colored in) point on the -2. So there are no y's less than -2 on the graph.
The graph continues to go up. Yes, it goes to the right, but we are looking at the y's. There is an arrow at the right end of the graph which means it continues to go up forever.
-2 <= y <= infinity

Dolbear's law states the relationship between the rate at which Snowy Tree Crickets chirp and the air temperature of their environment. The formula is T=50+n-40/4, where T is a temperature in degrees Fahrenheit and N is a number of chirps per minute. If T=57°F, find the number of chirps per minute.
Answer:
Number of chirps per minute = 68
Step-by-step explanation:
Given:
T = 50+ (N - 40)/4
where,
T is a temperature in degrees Fahrenheit
N is a number of chirps per minute
Find n when T = 57°F
T = 50 + (N - 40)/4
57 = 50 + (N - 40)/4
57 - 50 = (N - 40)/4
7 = (N - 40)/4
Multiply both sides by 4
7 × 4 = (N - 40)/4 × 4
28 = N - 40
28 + 40 = N
68 = N
N = 68
Number of chirps per minute = 68
An office supply store purchased a case of binders for $600. The profit (P) to be made on the binders is defined by the function
P(b) - 8.50b - 600, where b is the number of binders sold.
Part A What is the range of the function if the domain is {10, 45, 72, 100)?
Part B What do the domain and range represent in this situation?
Part C What is the minimum number of binders that the store needs to sell in order to make a profit (P >0)? Show or explain your work.
Part D What is the minimum profit the store can make on the sale of these binders? Show or explain your work.
Answer:
Part A
Domain = input values
Range = output values
Therefore, if the domain is {10, 45, 72, 100} then input those values into the function:
P(10) = 8.50(10) - 600 = -515
P(45) = 8.50(45) - 600 = -217.5
P(72) = 8.50(72) - 600 = 12
P(100) = 8.50(100) - 600 = 250
So the range is {-515, -217.5, 12, 250}
Part B
The domain is the number of binders sold
The range is the profit in dollars
Part C
Set the function to >0:
⇒ P(b) > 0
⇒ 8.50b - 600 > 0
add 600 to both sides:
⇒ 8.50b > 600
divide both sides by 8.50:
⇒ b > 70.58823529...
Therefore, the minimum number of binders the store needs to sell in order to make a profit is 71.
Part D
If the store sells a minimum of 71 binders, then substitute b = 71 into the function and solve to find the minimum profit:
⇒ P(71) = 8.50(71) - 600
⇒ P(71) = 603.5 - 600
⇒ P(71) = 3.5
Therefore, the store will make a minimum of $3.50 profit if it sells at least 71 binders.
However, if the store sells less than 71 binders, it will make a loss.

Answer:
m = 2.4 and b = 14.8
Step-by-step explanation:
In slope-intercept form, all equations follow the formula y = mx + b, in which equations are parallel as long as they have the same slope, represented by the variable m. All that the b variable does is change the y-intercept. Knowing this, in order to find a parallel equation to y = 2.4x + 5.2 that intercepts the point (-2, 10), the only variable that can change is the b variable. The first step is to plus -2 into the x variable. This will grant you y = 2.4(-2) or y = -4.8, which will then allow you to find what the b variable should be by subtracting -4.8 from 10. This will grant you b = 14.8, and since you know the slope must stay the same, the final answers are m = 2.4 and b = 14.8.

-2 + z = 10
-2 + z − 2 = 10 − 2
z = 8
Explain why Mateo's solution is incorrect. Then show how to correctly solve the equation.
if z = 8
then
-2 + (-8) = - 10
not 10
-2 + z = 10
-2 + 2 + z = 10 + 2
z = 12
