3 fair coins are tossed.
a) What is the probability of getting all 3 heads? (My Answer is 1/8)
b) What is the probability of getting all 3 tails? (My Answer is 1/8)
c) What is the probability of getting all 1 head and 2 tails? (My Answer is 3/8)
d) What is the probability of getting all 2 heads and 1 tail? (My Answer is 3/8)
My Question:
e) What do the probabilities from parts (a) to (e) add up to?
Answer:
1/8 + 1/8 + 3/8 + 3/8 = 2/8 + 6/8 = 8/8 = 1
So the answer would be 1.

The measure of Zo is 150°. What is the value of mZb+mZc+mze?
O 90°
ОООО
120°
210°
Answer:
∠b + ∠c + ∠e = 120°
Step-by-step explanation:
From the attached figure,
∠b + ∠e + ∠a = 180° (Linear pair)
Given that, ∠a = 90°
∠b + ∠e = 90° ...(1)
Also,
∠c + ∠d = 180° (Linear pair)
Given that,
∠d = 150°
∠c = 180°-150°
= 30°
Adding ∠c to both sides of the equation (1).
∠b + ∠e + ∠c= 90° + ∠c
∠b + ∠c + ∠e = 90° + 30°
= 120°
Hence, the meaure of ∠b + ∠c + ∠e is equal to 120°

Jillian and Dawn are playing a game of miniature golf. In this game, the score on a hole is the number of putts it takes to
get the ball into the hole. The winner is the player with the lowest score. After playing 18 holes, Jillian's mean is 2.4 and
Dawn's mean is 3.3. Which explains who won the game?
O Jillian won the game because her score varied less than Dawn's score.
O Jillian won the game because the person with the lower mean took fewer putts on average for each hole.
O Dawn won the game because the person with the greater mean played better.
O Dawn won the game because her mean absolute deviation was less than Jillian's.

6. Interpret your solution. How many days does it take Amir to catch Jesse? At that time, how many pages have they read?
Write your answer in the space below.
Answer:
Answer:
6 days
210 pages
Step-by-step explanation:
As stipulated by the question, let the number of days Amir has been reading be x and the number of pages he had read to be y.
Now since he reads 35 pages per day.
Then mathematically;
y = 35x
For Jesse, He started reading a day before, this means that the number of days he had read would be x + 1. Since he reads 30 per day, the total number of pages he would have read is 30(x+1)
To find the number of days which is x, we have to assume that at a point in time, the number of books they would have read would be the same meaning that
Also; y = 30(x + 1)
Equating the two situations
35x = 30(x + 1)
35x = 30x + 30
35x -30x = 30
5x = 30
x = 30/5
x = 6 days
This means that it will take Amir 6 days to catch Jese.
The number of books they would have read by then is y = 35x = 30(x + 1)
= 35 * 6 or 30(6+1)
= 210
Step-by-step explanation:
Answer: dude above me copied
Step-by-step explanation:
1. y = 35x
2. y = 30x + 1
3. y = 35x
y = 30 x + 1
4. Its more convenient to substitute y because It's easier.
35x = 30(x + 1)
5. 35x = 30x + 1
35x = 30x + 30
35x -30x = 30
5x = 30
x = 6 (30/5 = 6)
35 x 6 = 210 (y)
6. Both people have read 210 pages and it takes amir 6 days to catch up.

\cos (t) =

\tan (t) =
.
Answer:
The trigonometric ratios associated with (-5, -4) are [tex]\sin t \approx -0.625[/tex], [tex]\cos t \approx -0.781[/tex] and [tex]\tan t = 0.8[/tex].
Step-by-step explanation:
Let [tex]\vec u = (x,y)[/tex]. From Trigonometry, we remember the following definitions for the trigonometric ratios, dimensionless:
[tex]\sin t = \frac{y}{\sqrt{x^{2}+y^{2}}}[/tex] (1)
[tex]\cos t = \frac{x}{\sqrt{x^{2}+y^{2}}}[/tex] (2)
[tex]\tan t = \frac{y}{x}[/tex] (3)
If we know that [tex]x = -5[/tex] and [tex]y = -4[/tex], then the trigonometric ratios are, respectively:
[tex]\sin t = \frac{-4}{\sqrt{(-5)^{2}+(-4)^{2}}}[/tex]
[tex]\sin t \approx -0.625[/tex]
[tex]\cos t = \frac{-5}{\sqrt{(-5)^{2}+(-4)^{2}}}[/tex]
[tex]\cos t \approx -0.781[/tex]
[tex]\tan t = \frac{-4}{-5}[/tex]
[tex]\tan t = 0.8[/tex]
The trigonometric ratios associated with (-5, -4) are [tex]\sin t \approx -0.625[/tex], [tex]\cos t \approx -0.781[/tex] and [tex]\tan t = 0.8[/tex].

D. 2,787.64 yd
9514 1404 393
Answer:
D. 2,787.64 yd
Step-by-step explanation:
The formula for the volume of a cone is ...
V = (1/3)πr²·h
The radius (r) is half the diameter, so is (22 yd)/2 = 11 yd. Putting the given values into the formula, we have ...
V = (1/3)π(11 yd)²(22 yd) = 887.333π yd³ ≈ 2787.64 yd³ . . . . matches D

Answer:
y = 1/9 x z^3
Step-by-step explanation:
y is jointly proportional to x and z^3
y = k * x * z^3 where k is the constant of proportionality
y =12, x = 4 and z =3
12 = k * 4 * 3^3
12 = k * 4 * 27
12 = k * 108
12/108 = k
1/9 = k
y = 1/9 x z^3

Find an equation of the line L. L is perpendicular to y=-2x and is passing through points 2,-4
slope of line y= -2x is -2
slope of line L= (-1)reciprocal of slope line y= -2x.
=( -1)(-1/2)
=1/2
since the L passes through (2,-4),
equation of line L: y-(-4)= 1/2(x-2)
2y+8 = x-2
x-2y-10=0
Hence equation of line L is x-2y-10=0
The equation perpendicular to y = -2x and passing through point (2,-4) is y = x/2 - 5.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
The equation of a line with slope m is given by
y = mx + c
Now,
multiplication of slope of two perpendicular lines = -1
And,
Slope of line y = -2x ⇒ dy/dx = -2
So,
m × (-2) = -1 ⇒ m = 1/2
So,
y = (1/2)x + c
Now since it is passing by point (2,-4) so it should satisfy this
So,
-4 = 2/2 + c
c = -5
So,
y == x/2 - 5.
Hence "The equation perpendicular to y = -2x and passing through point (2,-4) is y = x/2 - 5".

Answer:
B.
Step-by-step explanation:
Plug in the x-values for x in the answer choices. The result will be the y-value of the table.
For example,
A. 3(-1)^2+3(-1)-2 = -2
That is not the y-value for -1, so A is not the answer.
B. 3(-1)^2-3(-1)-2=4.
4 works here, but make sure to try all the numbers.
3(0)^2-3(0)-2 = -2
3(3)^2-3(3)-2 = 16
B is the answer because with each x-value you substitute in for x, you get its corresponding y-value.
