Answer:
Probability by definition is the extent to which an event is likely to occur, measured by the ratio of the favourable cases to the whole number of cases possible.
Since number of elements in the set of favourable cases is less than or equal to the number of elements in the set of whole number of cases, their ratio would always end up being 1 or less than one.
Probability equals one when favourable number of cases are same as that of the whole number of cases and probability equals zero when there is no favourable case

Elena is right in saying that exponents are repeated multiplication, but shes doing it the incorrect way. 2 to the power of 28 is not multiplication of 28s twice, but instead is multiplication of 2 twenty eight times.

It snows 0.7 inch on Wednesday and 0.31 inch on Thursday. Brandon draws this model to find how much more snow fell on Wednesday than on Thursday.
Answer: 0.39 inch snow fell on Wednesday than on Thursday.
Step-by-step explanation:
We are given that, It snows 0.7 inch on Wednesday and 0.31 inch on Thursday.
According to this model,
more snow fell on Wdifferenceednesday than on Thursday because 0.7 > 0.31
To compute the difference we subtract the length of snow on Thursday from length of snow on Wednesday.
Difference = 0.7-0.31
= 0.39 inch
Hence, 0.39 inch snow fell on Wednesday than on Thursday.
A segment has endpoints V and X. What are two names for the segment?
Given:
A segment has endpoints V and X.
To find:
The two names for the segment.
Solution:
A line segment is a small part of a line and it has two end points. The name of a segment is described by its end points.
For example: If A and B are two and points of a line segment, then the names for the segment are [tex]\overline {AB}[/tex] and [tex]\overline {BA}[/tex].
It is given that the segment has endpoints V and X.
Therefore, the two names for the segment are [tex]\overline {VX}[/tex] and [tex]\overline {XV}[/tex].

( 3x - 12 / 9x^2 ) ÷ ( x - 4 / 3x ) =
( 3x - 12 / 9x^2 ) × ( 3x / x - 4 ) =
( 3 ( x - 4 ) / 3 × 3x × x ) × ( 3x / x - 4 ) =
( x - 4 / 3x × x ) × ( 3x / x - 4 ) =
( x - 4 ) × 3x / ( x - 4 ) × 3x × x =
1 / x

Answer: c
Step-by-step explanation:
solve the equation x - 4 = 6 HELLPL
Answer:
x = 10
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides of the equation:
x - 4 (+4) = 6 (+4)
x = 6 + 4
x = 10
x = 10 is your answer.
~
You get this result after adding 4 to both sides. This is to undo the "minus 4" happening to the x.
To check the answer, replace x with 10 and simplify each side like so
x-4 = 6
10-4 = 6
6 = 6
We get the same thing on both sides, so that confirms the solution.
I would really appreciate the help guys!

Two weeks ago Mike ran 10 miles for his longest run ever. Yesterday, Mike ran 14 miles for a new personal record. What the the percent change in Mike's long distance runs
Answer:
40%
Step-by-step explanation:
percent change in Mike's long distance runs = (change in miles ran / initial longest mile ran) x 100
change in miles ran = new personal record - initial personal record
14 - 10 = 4
(4/10) x 100 = 40%

Answer:
[tex]x = - 16[/tex]
Step-by-step explanation:
Let's solve:
[tex] \frac{3}{4} x = - 12[/tex]
Step 1: Multiply both sides by 4/3.
[tex]( \frac{4}{3} )*( \frac{3}{4} x)=( \frac{4}{3} )*(−12)[/tex]
[tex]x = - 16[/tex]
[tex] \frac{3}{4} x = - 12 \\ \\ = > 3x = - 12 \times 4 \\ \\ = > x = \frac{ \cancel{- 12} \times 4}{ \cancel3} \\ \\ = > x = - 4 \times 4 \\ \\ = > x = 16[/tex]

a = 22 × Cos( 60 )
a = 22 × 1/2
a = 11
Answer:
a = 11
Step-by-step explanation:
[tex]sin 60 = \frac{opposite}{hypotenuse} = \frac{b}{22}\\\\b = 22 \times sin 60 = 19.05[/tex]
[tex]22^2 = a^2 + b^2 \\484 = a^2 + 19.05^2\\a^2 = 484 - 362.9025\\a^2 = 121.0975\\a = \sqrt{121.0975} = 11.004[/tex]

Keisha's softball team won 60% of 135 games, how much games did the team lose?
Answer:
54
Step-by-step explanation:
135(.6) = 81
total = 135
won = 81
lost = 54
OR you could just multiply 135 by 110%-60%, which is 40% or 0.4
135(.4) = 54
for positive acute angles A and B, it is known that cos A=9/41 and tan B=21/20. Find the value of sin(A+B) in simplest form.
Answer:
Step-by-step explanation:
I attached a pic so you can see what the angles look like when you draw them out and construct right triangles out of them. We need to find the missing side lengths, ?, in each triangle. For A:
and
x = 40 For B:
and
x = 29. Now that we know all the sides of each triangle, we will use the sum identity for sin:
sin(A + B) = sinAcosB + cosAsinB. Filling in what we found in our triangles for each ratio: sin A = 40/41, sin B = 21/29, and cos B = 20/29
sin(A + B) = which simplifies to
And that's it. It doesn't simplify any further.
The volume of a sphere can be given by the formula V = 4.18879r. You have to design a spherical container that will hold
a volume of 55 cubic inches. What should the radius (r) of your container be? Round your final answer the nearest
hundreths place.
Answer:
2.36 inches
Step-by-step explanation:
V = 4.18879r³
to determine the value of r, make r the subject of the formula in the above equation
∛(V/4.18879) = R
∛(55/4.18879) = r
r = ∛13.130283
r = 2.36 inches
the hundredth is the second number after the decimal place. To convert to the nearest hundredth, look at the number after the hundredth (the thousandth). If the number is greater or equal to 5, add 1 to the hundredth figure. If this is not the case, add zero
which line is parallel to y = 1/2x + 6
and which line is perpendicular to y = 3x - 8
y = 1/2x + x where x is any real number
y= -1/3 + x where x is any real number
Answer: to make a line parallel to y = 1/2x + 6, just change the y-intercept (6), and to make a perpendicular line to y = 3x - 8, turn the slope (3x) into its opposite (1/3x).
