Answer:
Dependent: Cost of the ride.
Independent: Number of rides.
Step-by-step explanation:
The independent variable is the variable what we change and the dependent variable is the variables which changes because of that changes.
Here the total cost of the ride changes for any change in the number of rides.
So the number of rides is the independent variable, and the total cost of the ride is the dependent variable

Find the length of the radius. Write your answer as
a simplified radical.
Step-by-step explanation:
Hey there!
Here;
A chord of a circle AB is given with measure of 24 cm.
Let O be the centre of a circle and OP is perpendicular to AB.
Now, draw an imaginary line from O to B. [To make a radius].
Now;
[tex]bp = \frac{1}{2} \times ab[/tex]
[tex]bp = \frac{1}{2 } \times 24[/tex]
Therefore BP = 12.
Again;
You can clearly see that POB is a Right angled triangle.
Now,
Using Pythagoras relation we get;
[tex] {ob} = \sqrt{ {po}^{2} + {bp}^{2} } [/tex]
[tex]ob = \sqrt{ {8}^{2} + {12}^{2} } [/tex]
[tex]ob = \sqrt{64 + 144} [/tex]
[tex]ob = \sqrt{208} [/tex]
Therefore OB = 14.42.
As OB is a radius, the value of radius is 14.42.

what would x equal to if x equaled 4 in this: 4x
Answer:
x = 4 and the expression when evaluated at x = 4, is 16.
Step-by-step explanation:
For this problem, we will simply look at the wording of the question and the given expression. The question ask, "What would x be equal to if x equaled 4 in this: 4x?"
In the problem, we are already given that x = 4 in the following expression, so the answer to the question is x = 4. If we were to evaluate the expression when x = 4, we would say the following:
If x = 4, then:
4x
= 4(4)
= 16
Hence, the expression would be 16 if evaluated when x = 4.

Recall the hurricane relief fund context from the previous investigation. Bob set up a hurricane relief donation fund and started it off by donating $ 35 . Instead of tripling in value each day, suppose it doubled in value each day
This question is Incomplete
Complete Question
Recall the hurricane relief fund context from the previous investigation. Bob set up a hurricane relief donation fund and started it off by donating $ 35 . Instead of tripling in value each day, suppose it doubled in value each day
Complete the following table showing the account values at the end of each day.
Number of days since the initial investment, n Amount (in dollars) in the relief account, A
0 1 2 3 4
Answer:
Number of days(n) = Amount (in dollars) in the relief account(A)
0 = $35
1 = $70
2 = $140
3 = $280
4 = $560
Step-by-step explanation:
The formula for doubling time
P(t) = Po(2)^t/k
Where P = Amount after time t
Po = Initial Amount
t = number of days
k = Frequency at which it doubles
For 0 days
t = 0, k = 1, P(o) = $35
P(t) = Po(2)^t/k
P(0) = $35(2)^0/1
= $35(2)⁰
= $35 × 1
= $35
For 1 day
t = 1, k = 1 , P(0) = $35
P(t) = Po(2)^t/k
P(0) = $35(2)^1/1
= $35(2)¹
= $35 × 2
= $70
For 2 days
P(t) = Po(2)^t/k
t = 2, k = 1, P(0) = $35
P(0) = $35(2)^2/1
= $35(2)²
= $35 × 4
= $140
For 3 days
P(t) = Po(2)^t/k
t = 3, k = 1
P(0) = $35(2)^3/1
= $35(2)³
= $35 × 8
= $280
For 4 days
P(t) = Po(2)^t/k
t = 3, k = 1, P(0) = $35
P(0) = $35(2)^5/1
= $35(2)⁴
= $35 × 16
= $560

$80,000, and if it is installed, no losses from this type of incident will be incurred. However, if the generator is not installed, there is a 12% chance that a power outage will occur during a year. If there is an outage, there is a .07 probability that the resulting losses will be very large, or approximately $7 million in net aggregated loss. Alternatively, it is estimated that there is a .93 probability of only slight losses of around $1 million. Using decision tree analysis, determine whether the SPEA should have install the new power generator. What considerations may change your decision?
Answer:
SPEA should have install the new power generator.
Step-by-step explanation:
The information provided is as follows:
The cost of the emergency generator is $80,000, and if it is installed (I), no losses from this type of incident will be incurred. If the generator is not installed (I'), there is a 12% chance that a power outage (P) will occur during a year. If there is a power outage, there is a 0.07 probability that the resulting losses will be very large (HL), or approximately $7 million in net aggregated loss. Alternatively, it is estimated that there is a 0.93 probability of only slight losses (SL) of around $1 million.Consider the decision tree attached below.
The loss that will be incurred after the generator is installed is, $80,000.
Compute the loss that will be incurred if the generator is not installed as follows:
[tex]E(\text{Loss})=P(HL|P)P(P)\times \$7000000+P(SL|P)P(P)\times \$1000000[/tex]
[tex]=(0.07\times 0.12\times \$7000000)+(0.93\times 0.12\times \$1000000)\\=58800+111600\\=170400[/tex]
The loss that will be incurred if the generator is not installed is $170,400.
The loss from not installing the generator is more than from installing it.
Thus, SPEA should have install the new power generator.
The pumpkin patch had two corn mazes, as shown by the shaded and non-shaded sections in the model below. A model with 4 rows of 7 squares, representing 28 acres, and 2 rows of 7 squares, representing 14 acres. Which expression is shown by the model? 28 + 14 = 7 (4 + 14) 28 + 14 = 4 (7 + 2) 28 + 14 = 4 (14 + 28) 28 + 14 = 7 (4 + 2) ;p winner get brainliest no joke
Answer: 28+14 = 7 (4+2)
Step-by-step explanation:
The first option is incorrect because after you distribute 7 into (4 + 14), you get 28 + 14 = 28 + 98.The second option is incorrect because after you distribute 4 into (7 + 2), you get 28 + 14 = 28 + 8.The third option is incorrect because after you distribute 4 into (14 + 28), you get 28 + 14 = 56 + 112.The fourth option is correct because after you distribute 7 into ( 4 + 2), you get 28 + 14 = 28 + 14.Answer:

darla picked 4 times as many apples as oranges. if she picked a total of 20 apples and oranges, how many apples did she pick?
Answer:5
Step-by-step explanation:
Darrel has 36 daisies and 54 roses. He wants to put an equal number of daisies and roses into vases. What is the GREATEST number of daisies and roses Darrel
can put in each vase?
Answer:
18 number of daisies and 18 number of roses
Step-by-step explanation:
We are told Darrel has 36 daisies and 54 roses.
And that He wants to put an equal number of daisies and roses into vases.
To get the equal number, it means we have to find the greatest common factor of 36 and 54.
Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36
Factors of 54 = 1, 2, 3, 6, 9, 18, 27, 54
From the factors of both 36 and 54, the greatest common factor to both of them is 18.
Thus, the GREATEST number of daisies and roses Darrel can put in each vase is 18 each
Answer:
18

Which rate describes a unit price?
0 $0.01 for 12 seconds
0 $0.25 for 5 minutes
0 $1.00 for 4 hours
0 $5.00 for 1 day
Answer:
the third one
Step-by-step explanation:
A company manufactures wheels for in-line skates. The diameters of the wheels have a mean of 3 inches and a standard deviation of 0.1 inches. Because so many of their customers use the metric system, the company decided to report their production statistics in millimeters They report that the standard deviation is now 2.54 mm. A corporate executive is worried about this increase in variation. Should he be concerned
Answer: He should not be concerned
Step-by-step explanation:
The variation is still the same and has not changed because the only thing that changed are the units. A unit change does not mean that the diameter has changed, only the method of measuring it has changed.
Absolutely speaking, the diameter is still the same. A standard deviation of 0.1 inches is the same as a standard deviation of 2.54mm so the executive should not be worried.

Solve for h.
15.3 + 1 h =1.3- 1 h
Answer:
-7 = h
Step-by-step explanation:
15.3 + 1h = 1.3 - 1h
+1h +1h
15.3 + 2h = 1.3
Remember what you do to one side you MUST do to the other.
15.3 + 2h = 1.3
-15.3 -15.3
2h = -14
Now to isolate the variable you divide both sides by 2 to get, h = -7
Hope that helps and have a great day!
Hey there!☺
[tex]Answer:\boxed{h=-7}[/tex]
[tex]Explanation:[/tex]
[tex]15.3+1h=1.3-1h[/tex]
In our first step, we will simplify both sides in the equation:
[tex]15.3+h=1.3+-h\\h+15.3=-h+1.3[/tex]
Now add h to both sides:
[tex]h+15.3+h=-h+1.3+h\\2h+15.3=1.3[/tex]
In step 3, divide both sides by 2:
[tex]\frac{2h}{2}=\frac{-14}{2}[/tex]
Simplify -14/2:
[tex]\frac{-14}{2}=-7\\ h=-7[/tex]
h=-7 is your answer.
Hope this helps!☺
