Can someone help me and explain how to do these probability questions?
(for the last one, type out the question for say a, b, c, or d)
a. The probability is 1/100 since there are 10 possible digits (0-9) and you need the last two digits so [tex]\frac{1}{10}*\frac{1}{10}=\frac{1}{100}[/tex].
This is 1%.
b. Let's start by calculating the probability of getting the right digits knowing that they are both even.
We have a total of 5 even digits (0, 2, 4, 6, 8). You need the last two so [tex]\frac{1}{5}*\frac{1}{5} =\frac{1}{25}=\frac{4}{100}[/tex] which is 4%.
Therefore the answer is a) It increases the probability that your choice is correct to 1/25, or 4%, because each digit could be 0, 2, 4, 6 or 8.
The radius of a quarter circle is 3 inches. What is the quarter circle's area?
Area of quater of circle is [tex]\frac{\pi r^2}{4}[/tex]
Radius = 3
(A = Area)
A = [tex]\frac{3^2\pi }{4}[/tex]
A = [tex]\frac{9\pi }{4}[/tex] (The order of steps doesn't matter whether you divide 9 by 4 first or times 9 with [tex]\pi[/tex]. I'm going to divide 9 with 4 first)
A = 2.25[tex]\pi[/tex]
Area (With [tex]\pi[/tex] --> 3.14 aprx.) = 7.065

Look at this square. Find the value of a.
Answer:
18
Step-by-step explanation:
A square has 4 sides of equal length.
The perimeter of the square is the sum of the lengths of the sides of the square.
P = perimeter; a = length of 1 side
P = a + a + a + a
P = 4a
We are told the perimeter is 72 yd.
4a = 72 yd
Divide both sides by 4.
a = 72/4 yd
a = 18 yd

 hey! This is due at like 11 pm!
Answer:
V=150.72
Step-by-step explanation:
The formula for the volume of a cylinder is V= \pi x r^2 x h
So you would do 3.14x4^2x3
4^2 is 16 so then you have 3.14x16x3, multiply them all together and get 150.72! Hope this helped :)
find the 5 consecutive odd integers if the sum of the first integer is 7 more than the sum of the last 2
Answer: 15,17,19,21,23
Step-by-step explanation:
You can let the middle number = x, then the numbers are
x-4, x-2, x, x+2, x+4
Plugging it back in to what is given,
x-4+x-2+x = 7+x+2+x+4
3x-6 = 2x + 13
x = 19
The numbers are 15, 17, 19, 21, 23

q + 2.02 = 9.2
What does q equal?
Answer:
7.18
Step-by-step explanation:
remember you can rearrange the equation by doing the SAME THING on BOTH SIDES.
q + 2.02 -2.02=9.2-2.02
simplify and you get:
q=7.18
Answer:
7.18 {final answer}
Step-by-step explanation:
→ q + 2.02 = 9.2
→ q = 9.2 - 2.02
→ [ q = 7.18 ]

Is 36 T-shirts in 3 boxes equivalent to 60 T-shirts in 6 boxes?
Answer:no it is not equivalent
Step-by-step explanation:
36x3=108 so there is 108 shirts in that box
60x6=360 so 360 is in that box
so not equivalent because they have different amounts in the boxes one is more and the other one less
your welcome
Answer:
No
Step-by-step explanation:
Since the unit rates 12 t-shirts/1 box
and 10 t-shirts/1 box are not the same, the rates are not equivalent.

A student claims that the expression “9 times the sum of a number and 13” is translated to the algebraic expression 9n + 13. Is the student correct? If not, what is the correct expression?
Answer: The student is wrong. The correct algebraic expression is 9(n + 13)
The algebraic expression is represented as follows:
The sum of a number and 13 is represented as follows:
Let
n = the number
Therefore,
The sum of a number and 13 is:
n + 13
9 times the sum of a number and 13” can be translated as follows:
9(n + 13)
Therefore, the student is wrong.

Can you guys help? Hopefully the last question of the day/night!
Answer and explain:
1st person: 70 % throws
70/100x80 = 56 out of 80 throws
2nd person: 60% throws
60/100x80 = 48 out of 80 throws
3rd person 50% throws
50/100x80 = 40 out of 80 throws
56+48+40/80x3 = 77/120
One equation that gives the estimated number of free throws (all the 3 people) is 77 out of 120. The best player will make about 56 out of 80 free throws.
