In a high school basketball game, a player on the home team makes two free throws. One student asks the student next to her what he thinks the probability of hitting two free throws in a row is. The student replies, "The probability of him making a free throw is probably about .6, so hitting two free throws is probably about 1.2." Why can this immediately be dismissed as incorrect?
A.
The final number, 1.2, is a fraction, which can never represent a probability.
B.
The probability of making a free throw can never be .6.
C.
The probability of an event happening twice in a row can never be equal.
D.
The final number is greater than 1, which is not a valid probability.
Answer:
DStep-by-step explanation:
The probability can be expressed as a number between 0 and 1 or a percent value between zero and 100%.
Correct choice is:
D. The final number is greater than 1, which is not a valid probability.Which pair of points should be used to find the line of best-fit for the scatterplot?.

- 8/9x - 4/45x + 1/5x = - 70
Answer:
x = 90
Step-by-step explanation:
- [tex]\frac{8}{9}[/tex] x - [tex]\frac{4}{45}[/tex] x + [tex]\frac{1}{5}[/tex] x = - 70
Multiply through by 45 ( the LCM of 9, 45, 5 ) to clear the fractions
- 40x - 4x + 9x = - 3150 , that is
- 35x = - 3150 ( divide both sides by - 35 )
x = 90
what is the answe ?????
Hello there!
The right prime factorization is
2*2*2*3*11 because 2 and 3 and 11 are prime.
Take a look at the words "prime" and "factorization"
Can you see something that looks like "prime factors?" Exactly!
2 is prime. 3 is prime. 11 is also prime.
A prime number is only divisible by 1 and itself.
What is the value of 5+2*15+(12*4)?
If you remember "Please Excuse My Dear Aunt Sally" that's great as long as you know what that means.
P = Parentheses
E=Exponents
M=Multiplication
D=Division
A=Addition
S=Subtraction
5+2*15+(12*4)=5+2*15+(48)=5+30+48=83

I will only give brainliest if you do 14-23
I see you need help with 14 - 23 evens, so hopefully this is what you need. If not, comment and I will edit it as appropriate :) Have a nice day
14: It is slightly hard to see, but I am going to say 15 mm. We can decide this because the ruler says it is in mm and on both sides are 10 and 20. It is in the middle so we will decide the answer is 15.
16: 3,629 - 429 = 3,198 (not much explanation, just use a calculator or do the subtractation)
18: 491 * 700 = 343,700 (multiply 491 * 7, then add the two zeros onto the end of the answer because it's 700, not 7)
20: 5n = 3,175 ; n = 635 (divide both sides of the equation by 5)
22: See pictured below
After that, 2/3 is equal to 0.66666666666, which we can round to 67%
Even though it is not an even, you said "14 - 23" so here is 23 as well:
230, 240, 250, 260, 270, etc
/\
256 is inbetween here
It is above 5, so the answer is C 260
What is the solution to the system of linear equations? 2x + 3y = 3 3x + 5y = 5 Enter you answer into the boxes.
Answer:
x = 0
y = 1
Step-by-step explanation:
2x + 3y = 3 Multiply this equation by 3
3x + 5y = 5 Multiply this equation by 2
3(2x + 3y = 3)
6x + 9y = 9
2(3x + 5y = 5 )
6x + 10y = 10 Notice the xs are the same.
6x + 9y = 9
6x + 10y =10 Subtract
- y = - 1 Multiply each side by -1
y = 1
2x + 3y = 3
2x + 3*1 = 3
2x = 0
x =0
can you plz find this witj equation
Find the missing side of each triangle. Round your answers to the nearest tenth if necessary. (Please Show your work)
Answer:
12.2 mi
Step-by-step explanation:
We need to use the Pythagorean theorem, we can use the equation A^2 + B^2 = C^2 then get the square root of the answer
plugging in the numbers with the equation we get the equation:
10.6^2 + 6.1^2 = c^2
then we multiple the available numbers by their exponents we get:
112.36 + 37.21 = c^2
Adding the numbers together we get:
112.36 + 37.21 = 149.57
Get the square root of 149.57 (Since the earlier equation was just everything squared) we get:
12.2298814385
Round it to the nearest tenth as directed, then we get:
12.2
The answer is 12.2 mi

A 3 fl oz bottle of orange juice costs $21 and a 6 fl oz. bottle of orange juice
costs $36. Which is a better buy?
Answer:
6floz bottle of orange juice.
Step-by-step explanation:
21*2=42
$42 for 6floz of juice vs $36 for the same amount. 36 is the better deal!
Answer:
6 fl oz. bottle of orange juice
Step-by-step explanation:
For the 6 fl oz bottle to be equal to the 3fl oz bottle prize, it would need to cost 42, but since it only costs 36$, it would be the better deal.

solve X
8-x/10=11
please help me
Answer:
x = -102
Step-by-step explanation:
Step 1: Multiply both sides by 10.
[tex]\frac{8-x}{10} * 10 = 11*10[/tex] [tex]8-x = 110[/tex] [tex]-x + 8 = 110[/tex]Step 2: Subtract 8 from both sides.
[tex]-x + 8 - 8 = 110 - 8[/tex] [tex]-x = 102[/tex]Step 3: Divide both sides by -1.
[tex]\frac{-x}{-1} = \frac{102}{-1}[/tex] [tex]x=-102[/tex]Step 4: Check if solution is correct.
[tex]\frac{8-(-102)}{10} = 11[/tex] [tex]\frac{8+102}{10}=11[/tex] [tex]\frac{110}{10}=11[/tex] [tex]11 = 11[/tex]Therefore, x = 11.
