The probability that Maria succeeds at any given free-throw is 75%. She was curious how many free-throws she can expect to succeed in a sample of 10 free-throws. She simulated 25 samples of 10 free-throws where each free-throw had a 0.75 probability of being a success. Maria counted how many free-throws were successes in each simulated sample. Here are her results:
Answers
Answer:
5: 0 successes
6: 5 successes
7: 8 successes
8: 6 successes
9: 6 successes
10: 1 success
We need to use her results to estimate the probability that she succeeds at fewer than 7 free-throws in a sample of 10 free-throws.
First, find out how many successes were less than 7 (out of 25), which is 5.
now, we divide 5 by 25 (5/25, formula being number/total attempts) and simplify into a decimal, which comes out to 0.2
Probability w/ Venn Diagrams
Step-by-step explanation:
Disclaimer: The question was incomplete. The complete question can be seen in the image attached.
The estimated probability of Maria succeeding at fewer than 7 free throws in a sample of 10 free throws is 1/5 or 0.2.
What is the probability of an event?The probability of an event is the fractional value showing how likely is that event to occur. It is determined by the formula =
The number of outcomes favorable to the event/the total number of outcomes.
How do we solve the given question?The results from the 25 samples showing the number of success in each trial of 10 throws are:
5 success: 0 outcomes
6 success: 5 outcomes
7 success: 8 outcomes
8 success: 6 outcomes
9 success: 5 outcomes
10 success: 1 outcome.
We are asked to estimate the probability that Maria succeeds at fewer than 7 throws in a sample of 10 free throws.
From the result of 25 samples of 10 free throws each, we see that Maria succeeds fewer than 7 times, that is, 5 and 6 times for 0 + 5 = 5 outcomes.
∴ The probability of Maria succeeding at fewer than 7 throws in a sample of 10 free throws = 5/25 (favorable outcomes/total outcomes)
= 1/5 or 0.2.
So, the estimated probability of Maria succeeding at fewer than 7 free throws in a sample of 10 free throws is 1/5 or 0.2.

Answers
Answer:
yes
Step-by-step explanation:
30% of 42 is 12.60 so 42.00 +12.60= 54.60
and 25% of 54.60 is 13.65 so 54.60 + 13.65 = 68.25
so the Original price is $68.25
The original price of the phone case is $93.33
What is a discount?Discounting is the process of determining the present value of a payment or a stream of payments that is to be received in the future.
Given that, the phone case, is marked down 30%, and we have a 25% off coupon, paid $42.00, for this in whole, we are asked to find the original price,
Let the original price be x,
Therefore,
x - (30% of x + 25% of x) = 42
x - (30/100 · x + 25/100 · x) = 42
x - (0.3x + .25x) = 42
x - 0.55x = 42
0.45x = 42
x = 93.33
Hence, the original price of the phone case is $93.33

Answers
Answer:
Number of large oranges: x
Number of small oranges: y
y < 6
x + y <= 10
Hope it helps!!!!!!brainliest pls!!!!!!!!The girl can buy a minimum of 3 oranges (either 3 large or 3 small) and a maximum of 10 oranges (a combination of large and small).
Let's represent the number of large oranges as "L" and the number of small oranges as "S."
From the given information, we have the following conditions:
At least three but fewer than nine large oranges: 3 ≤ L < 9
Fewer than six small oranges: S < 6
The maximum number of oranges she needs to buy is 10: L + S ≤ 10
Now, let's consider the possible combinations of L and S that satisfy these conditions:
L = 3, S = 0 (Total oranges = 3)
L = 4, S = 0 (Total oranges = 4)
L = 5, S = 0 (Total oranges = 5)
L = 6, S = 0 (Total oranges = 6)
L = 7, S = 0 (Total oranges = 7)
L = 8, S = 0 (Total oranges = 8)
L = 3, S = 1 (Total oranges = 4)
L = 4, S = 1 (Total oranges = 5)
L = 5, S = 1 (Total oranges = 6)
L = 3, S = 2 (Total oranges = 5)
L = 4, S = 2 (Total oranges = 6)
L = 3, S = 3 (Total oranges = 6)
As you can see, these are all the possible combinations of L and S that satisfy the given conditions. The girl can buy a minimum of 3 oranges (either 3 large or 3 small) and a maximum of 10 oranges (a combination of large and small).

Answers
Addison needs to cut $45 from Food/Clothes and $41 from Entertainment, to pay the revised monthly payment.
It is given that
Addison has a balance of $3,450 on her credit card.
APR = 18%
Current monthly payment = $86.25
She wants to choose a monthly payment for 24 months.
So for 24 months,
A revised monthly payment using the formula,
[tex]M = \frac{P.\frac{R}{12}. (1+\frac{R}{12} )^N }{(1+\frac{R}{12})N -1}[/tex]
R = 0.18
P = 3450
N = 24
Revised montly payment M = $172.24
Current monthly payment = $86.25
Difference = $86
So, she needs to cut the expenses by $86
If she cut $45 from Food/Clothes and $41 from Entertainment, she can easily pay the revised monthly payment.
Therefore, Addison needs to cut $45 from Food/Clothes and $41 from Entertainment, to pay the revised monthly payment.

Marcus is buying a plane ticket. If he purchases his ticket on the day of his departure, it will cost $239. The ticket costs less if he buys it earlier. If he purchases it 20 days before his departure, it will cost $189. Model this situation by using a linear function. Then determine the cost of the ticket if Marcus buys it 3 days before his departure.
Answers
The modelled situation in a linear format is y = [tex]-\frac{5}{2}x+239[/tex]
The cost of the ticket if Marcus buys it 3 days before his departure is $231.5
Linear equationy = mx + b
where
m = slope
b = y-intercept
b = 239
Therefore, let's model the situation to a linear equation.
y = mx + 239
using (20, 189)
189 = 20m + 239
189 - 239 = 20m
-50 = 20m
m = [tex]-\frac{5}{2}[/tex]
Therefore,
y = [tex]-\frac{5}{2}x +239[/tex]
where
x = The day before departure
y = cost of ticket
To determine the cost of the ticket if Marcus buys it 3 days before his departure.
y = [tex]-\frac{5}{2}(3)+239[/tex]
y = -7.5 + 239
y = $231.5

Step-by-step explanation:
Let us start off by isolating each of the two different length sides, and figure out which fence pieces can be used to it off.
For the three meter (3 m) side, we could utilize the following THREE (3) pieces...
ONE (1) piece of 1.8 m length fenceTWO (2) pieces of 0.6 m length fenceAdding up those pieces provides us with our desired garden side length...
(1 × 1.8 m) + (2 × 0.6 m) = 3.0 m!
For the six meter (6 m) side, we could utilize the following THREE (3) pieces...
ONE (1) piece of 1.8 m length fenceTWO (2) pieces of 2.1 m length fenceAdding up those pieces provides us with our desired garden side length...
(1 × 1.8 m) + (2 × 2.1 m) = 6.0 m!
We ought to not forget about the opposite sides of the aforementioned, to make up the four sides of the rectangle! In short, we double the number of pieces that we currently have...
In the end, the smallest number of pieces of fence that Esme will need to buy is TWELVE (12), consisting of the following pieces:

Answers
The area of the shaded rectangle is 18 square units.
How to get the area of the shaded region?
The shaded region is the framed rectangle, and the white part is the frame.
We know that the frame is 2 units wide, and the measure of the rectangle and the frame are:
width = 7 unitslength = 10 unitsNow, if we remove the frame, we will remove 2*2 units = 4 units for each measure (because for each measure we have the frame in both sides).
So the measures for the shaded rectangle are:
width = 7 units - 4 units = 3 unitslength = 10 units - 4 units = 6 units.And the area of a rectangle is given by the product between the width and length, then we have:
A = (3 units)*(6 units) = 18 square units.
