A basketball player has made 80% of his foul shots during the season. Assuming the shots are independent, find the probability that in tonight's game he does the following. a) Misses for the first time on his fourth fourth attempt b) Makes his first basket on his fourth fourth shot c) Makes his first basket on one of his first 3 shots
a) The probability of missing for the first time on the fourth attempt is 0.16%. b) The probability of making the first basket on the fourth shot is 0.8%. c) The probability of making the first basket on one of the first 3 shots is 99.2%.
Explanation:a) To find the probability that the basketball player misses for the first time on his fourth attempt, we need to consider that each shot is independent. Since he has made 80% of his shots, the probability of making a shot is 0.8. Therefore, the probability of missing a shot is 1 - 0.8 = 0.2. Since the shots are independent, the probability of missing on the fourth attempt is 0.2 raised to the power of 4 = 0.0016, or 0.16%.
b) To find the probability that the basketball player makes his first basket on his fourth shot, we use a similar approach. The probability of making a shot is 0.8, and the probability of missing a shot is 0.2. The probability of making a shot on the fourth attempt is then 0.2 raised to the power of 3, multiplied by 0.8 = 0.2 * 0.2 * 0.2 * 0.8 = 0.008, or 0.8%.
c) To find the probability that the basketball player makes his first basket on one of his first 3 shots, we need to find the complementary probability. The probability of not making a basket on the first 3 shots is 0.2 raised to the power of 3 = 0.008. Therefore, the probability of making a basket on one of the first 3 shots is 1 - 0.008 = 0.992, or 99.2%.

1. Correct. The reflection happens over segment AB and then you translate 6 units to the right and 3 units up. This will move point A to D, B to F, C to E, to have the triangles line up perfectly.
-----------------------------------------------
2. Problem 1 already confirmed the triangles are congruent based on how they line up perfectly. Another way to prove this is to either use the SAS (side angle side) or LL (leg leg) theorem. With SAS, we need a pair of congruent sides and a pair of angles, with the angles between the two sides. The horizontal and vertical sides can be easily measured. The angles between the two sides are 90 degree angles. Because we have right triangles, we can use LL which is really just a special case of SAS.
-----------------------------------------------
3. Segment EF is 5 units. You can use the pythagorean theorem with a = 3 and b = 4 to solve a^2+b^2 = c^2 to get c = 5. Or you can use the fact that BC = 5 is given to us, so EF must also be 5 as well. This is because of the idea that if two triangles are congruent, then their corresponding pieces must be the same as well.
Real world example: imagine having 2 houses that are perfect clones of each other. If this is the case, then surely their front doors would be identical copies as well. In this analogy, a house is a triangle, while the front door is the segment.

In May, 2018 a store had a furniture with a listed price of $550, having a sales tax of 3% on the listed price. Next month the price increased by 33 1/3 %. What sales tax should be paid in dollars on the new price?
Answer:
$22
Step-by-step explanation:
Listed price = $550
Sales tax rate = 3%
The price increased by 33 1/3% or [tex]\frac{100}{3}[/tex]% in the next month
Now, Sales tax will be calculated on new price after increase price.
Price increase = \frac{100}{300}*550 = 183.33
New Price = 183.33+550 = 733.33
Since Sales tax =3% on 733.33
= \frac{3}{100}*733.33
= 21.99 =22(aprox)
Sales tax paid in dollars the next month after increase of price = $22
which rate describes a unit price? $1.00 for 2 lemons $3.00 for every pound $4.00 for 3 slices of pizza $6.00 for every 6 bottle
Final answer:
A unit price is the price for one unit of an item. Among the options provided, $3.00 for every pound represents a unit price because it tells us the cost per single pound.
Explanation:
The question asks which rate describes a unit price. A unit price is the cost per single item or measure. It is calculated by dividing the total price by the number of units. In the context of the examples provided, a unit price is expressed as a cost for one lemon, one pound, one slice of pizza, or one bottle.
$1.00 for 2 lemons => $0.50 per lemon$3.00 for every pound => $3.00 per pound (this is a unit price)$4.00 for 3 slices of pizza => $1.33 per slice of pizza$6.00 for every 6 bottles => $1.00 per bottleTherefore, out of the provided options, $3.00 for every pound best represents a unit price as it is a rate describing the cost of one pound.

Answer:
$200L+$100B ≥$5000
Step-by-step explanation:
Given :
Hyun Yong wants to donate more than $5000 in laptops and bicycles.
Each laptop that he donates is worth $200, and each bicycle that he donates is worth $100.
To Find : An inequality that represents the number of laptops (L) and bicycles (B) that Hyun Yong should donate to achieve his goal.
Solution :
L denotes the number of laptops.
Since cost of each laptop is $200
Thus cost of L laptops = $200L
B denotes the number of bicycles.
Since cost of each bicycle is $100.
Thus cost of B bicycles = $100B
Now, he wants to donate more than $5000 in laptops and bicycles
So, inequality will be : $200L+$100B ≥$5000
Hence, An inequality that represents the number of laptops (L) and bicycles (B) that Hyun Yong should donate to achieve his goal:
$200L+$100B ≥$5000

I'm so confused. Please help I tried the first time got 50 some thing then 33 then 20.25. How do I do this?
Answer:
Basically, you have to think: more bricks : more time
more workers : less time
2,400 bricks 6 workers takes 18 hours
You now have to solve for 4,500 blocks and 10 workers
4,500 / 2,400 = 1.875 (times greater)
10 / 6 = 1.666666666 (times less)
So, we get 18 hours, multiply it by 1.875 and divide it by 1.666666666
which equals 20.25 hours
So, it seems you were correct on your third try.

Nancy is 5 years younger than her brother Stan. Last year she was twice as young as he was. How old is each of them now?
Answer:
Nancy is 6 years old and Stan is 11 years old now.
Step-by-step explanation:
Let the present age of Stan be x.
Then age of Nancy = y
x - y = 5
Last year she was twice as young as he was
Age of Nancy last year = y-1
Age of Stan last year = x-1
2 × (y-1)= x-1
2y -2 = 5 + y -1
y = 6
x = y + 5 = 6 + 5 = 11
Nancy is 6 years old and Stan is 11 years old now.
The regular price of a jacket is $200. Today, the jacket is on sale. It is 20% off its regular price. The sales tax is 8%. If Steven buys the jacket today, how much will he pay?
Answer:
$172.80
Step-by-step explanation:
200*20%=40
200-40=160
160*0.08=12.8
12.8+160=172.80
Answer:
He pays $176
Step-by-step explanation:
First, to find 80% of 200, we can simply multiply 200 by .8.
200 x .8=160
Then, we add sales tax to that number. To find 8% of 200, multiply 200 by .08.
200 x .08=16
Then, add 16 to 160.
160+16= 176
Your answer is $176.

Answer:
k=15
Step-by-step explanation:
does the equation 7x-4y=0 represent a direct variation? what is the constant of variation?
Yes, the equation 7x-4y=0 represents a direct variation with the constant of variation being 7/4.
The equation 7x-4y=0 does represent a direct variation. To see this, we can rearrange the equation into the form y = kx, which is the general form for direct variation. Solving for y, we divide both sides by -4 to get:
y = (7/4)x
Here, the coefficient of x, which is 7/4, is the constant of variation. Thus, in the given equation, the constant of variation is 7/4, meaning for every unit increase in x, y increases by 7/4 units. This proportional relationship where y varies directly as x, with a constant ratio of 7/4, confirms it's a direct variation.

(3x-6)(-x+3)-0
smaller x=?
larger x=?
Answer:
x=2 and x=3
Step-by-step explanation:
(3x-6)(-x+3)=0
We can use the zero product property to solve for x
3x-6 = 0 and -x+3 =0
3x-6 = 0
Add 6 to each side
3x-6+6 = 6
3x=6
Divide by 3
3x/3 =6/3
x =2
-x+3 =0
Add x to each side
-x+x+3 = +x
3 =x
