All of the letters of MISSISSIPPI are put in a bag. What is the probability of selecting an M and then after not replacing the letter, selecting a P?
Answer:
2/110
Step-by-step explanation:
Picking the letter M is 1/11 because there is 1 letter M in the 11 letters of the word.
Selecting a P is 2/10 because there are 2 letter P's in the 10 letters( Letter M was taken out)
Multiply the 2 fractions
1/11 x 2/10 = 2/110

What does a correlation coefficient of 0.25 say about this graph?
x and y have a strong, positive correlation
x and y have a weak, positive correlation
x and y have a strong, negative correlation
x and y have a weak, negative correlation
Answer:
the answer is x and y have a weak, positive correlation.
Step-by-step explanation:
if a correlation is strong, it will either be close to 1 or -1 and the further in the decimal, the weaker the correlation becomes. the correlation is positive so that’s how I got the positive.

I’m trying to help my sister out can you help!!
On its first play of the game, a football team gained 6 yards. On its next
team lost 2 yards and then gained 7 yards. Use integers to describe these three plays.
What integer represents a play in which the team neither gains yards nor loses yards?
A play that gains yards would be represented by a
integer
A play that loses yards would be represented by a
integer.
On the first play, the team gained
yards.
A gain of 6 yards is represented by the integer
On the second play, the team lost
yards.
A loss of 2 yards is represented by the integer
On the third play, the team gained
yards.
A gain of 7 yards is represented by the integer
The three plays can be described by the integers
and
It shows your screenshot, but I've filled in the blanks with the answers.
====================================================
Explanation:
Positive integers represent yards that the team gains. On the opposite side, negative integers represent yards the team loses.
For example, if a team gains 3 yards, then we write that as +3 or simply 3. If a team loses 5 yards, then we write -5. Adding 3 to -5 gets us 3+(-5) = -2 showing the overall result is a loss of 2 yards at the end of the second down.
As another example, if a team gains 7 yards on first down, but then loses those 7 yards on second down, then they gained overall 7+(-7) = 0 yards overall. They haven't gone anywhere at the end of the second down.
We could do things the other way around like this. Suppose the team loses 8 yards on first down, but has better luck on second down to gain 8 yards. They get back to the original line of scrimmage (back to the starting point) and we can say -8+8 = 0. The team hasn't gone anywhere, but it could be worse and they could be dealing with a loss of yardage.
It might help to set up a vertical number line to help try to visualize negative numbers. Each gain means you go upward. Each loss means you go downward. In a sense, it's like a skyscraper and each integer represents floors of the building. Negative integers are basement floors. Zero is the ground level.

Solve the right triangle. See image below.
Hi there! You still remember the Pythagorean Theorem, right? It's useful when it comes to finding a missing leg or side of a right triangle. If you forget then here it is:
[tex] \large \boxed{ {a}^{2} + {b}^{2} = {c}^{2} }[/tex]
Define c = hypotenuse while a and b can be both adjacent and opposite (because a²+b²=b²+a² via addition property)
Since we are missing the adjacent side. Thus,
We define a = 6 and c = 14.
[tex] \large{ {6}^{2} + {b}^{2} = {14}^{2} } \\ \large{36 + {b}^{2} = 196} \\ \large{ {b}^{2} = 196 - 36} \\ \large{ {b}^{2} = 160} \\ \large{ b = \sqrt{160} \longrightarrow \boxed{b = 4 \sqrt{10} }}[/tex]
Put the value of b in a calculator then round to the nearest tenth and get 12.6
Thus, the value of b ≈ 12.6
Next we are going to find the angle in degree. We now know that b ≈ 12.6 or 4sqrt(10)
We can find the value of angle A by using tan or sin but I will use sin instead. Recall the sine ratio which is opposite to hypotenuse. Thus,
[tex] \large{sinA = \frac{6}{14} }[/tex]
Use arcsin(6/14) and put it in calculator.
Then put the decimal value of arcsin in sin and convert in degree form which we should get 24. 555°. Round to the nearest whole number and we get 25°
Thus, the angle A is 25°
Next is we are finding the value of angle B. We aren't going to use any formula or equation. Recall that three angles add up to 180°.
Thus, 25° + 90° + x = 180°
90° comes from a right angle.
115+x = 180
x = 180-115
x = 65°
Thus, the angle B is 65°
Answer
b ≈ 12.6 or 4sqrt(10)angle A = 25°angle B = 65°Find the slope of a line parallel to a line with a slope of 4/5
Answer:
slope = 4/5
Step-by-step explanation:
The question is asking us to find the slope of the line that's parallel to the line whose slope is 4/5.
Recall that parallel lines have equal slopes.
So the slope of the line that's parallel to the one with a slope of 4/5 is 4/5 too.
Therefore, slope = 4/5.

Is
X 10 11 12
Y 18 18.6 19.2 proportional or non proportional
Given:
The table of values.
To find:
Whether the given table is a proportional or non proportional relation.
Solution:
If y is proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
[tex]\dfrac{y}{x}=k[/tex]
Where, k is the constant of proportionality.
Find the value of k for each ordered pairs in table. If the value of k is constant, then the relation is proportional.
The ordered pairs from the table are (10,18), (11, 18.6), (12,19.2). The values of k for each ordered pair is:
[tex]\dfrac{18}{10}=1.8[/tex]
[tex]\dfrac{18.6}{11}\approx 1.69[/tex]
[tex]\dfrac{19.2}{12}=1.6[/tex]
Since the value of k is not constant, therefore the given table represents a non proportional relationship.
You are buying six hats and have a coupon for 15 dollars off. You spend $45. How much is each hat?
Answer:
$10
Step-by-step explanation:
6x-15=45
+15. +15
6x=60
/6. /6
x=10
Answer:
$7.5¢ or [tex]7\frac{1}{2}[/tex]
Step-by-step explanation:
Do not use This solution:
Firstly, lets find how much the hats cost initially before the 15% coupon. To do that, divide, not multiply, divide $45 by 15% because 15% off means multiply 15% from the original price. But in this case we need to find the initial amount before the 15% coupon.
15% = [tex]\frac{15}{100}[/tex]
Now, set it up;
[tex]\frac{15}{100}[/tex] ×[tex]\frac{45}{1}[/tex]
Correct solution!45 ÷ 6 = 7.5

The solid below was made by cutting a cone-shaped hole out of a cylinder. The surface area of the resulting composite solid is square cm. Write your answer in terms of pi.
*see attachement below for the diagram
Answer:
(252π + 20) cm²
Step-by-step explanation:
The surface area of the resulting solid = curved surface area of the cylinder + area of 1 base of the cylinder + 2(slant height of the cone)
✔️Curved surface area of cylinder = 2πrh
r = ½(12) = 6 cm
h = 18 cm
C.S.A = 2*π*6*18 = 216π cm²
✔️Area of 1 base = πr²
r = ½(12) = 6 cm
Area = π*6²
Area = 36π
✔️Slant height of the cone = 10 cm
✅The surface area of the resulting solid = 216π + 36π + 2(10)
= (252π + 20) cm²

when the line touch the circle you have to take the half of it
for b its equal 144
the full circle degree is 360
so we can say the 82+2x=360
because the two lines in the circle equal each other so its means tha the Piece of the circle in the left is equal b too

A laptop computer is purchased for $2000. After each year, the resale value decreases by 25%. What will the resale value be after years?
Use the calculator provided and round your answer to the nearest dollar.
$[]
Answer:
2000? ... assume $2000
Resale Value = $2000*(1 - 0.25)t/yr
where: t = number of year after purchase
at t = 3 yr
Resale Value = $2000*(1 - 0.25)3 = $843.75
checking: at t = 0 $2000 (purchase price)
at t = 1 yr $2000 - 0.25*$2000 = $2000 - $500 = $1500
at t = 2 yr $1500 - 0.25*$1500 = $1500 - $375 = $1125
at t = 3 yr $1125 - 0.25*$1125 = $1125 - $281.25 = $843.75

All lines are congruent to one another.
Answer:
This is false. Lines will be congruent if they have the same length, which is not the case in all situations.
Answer:
Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. In the figure above, there are two congruent line segments.
