Answer:
2) [tex]\frac{1}{\sqrt[6]m^{5}}[/tex]
Step-by-step explanation:
As per the laws of indices:
[tex]\frac{x^{a} }{x^{b} } = x^{a - b} \\\\and \\ \\(x^{a})^b = x^{ab}[/tex]
Therefore:
2-(1/3) = 5/3
So m ^(5/3)
5/3 multiplied by -1/2 = -5/6
so m^(-5/6)
Another law of indices:
[tex]x^{\frac{a}{y} } = \sqrt[y]{x^{a} }[/tex] and when there is something raised to a negative fraction do the reciprocal.

Lin read 44 pages in 132 minutes. Diego read 35 pages in 140 minutes. Who is reading at a faster rate, Lin or Diego? Show and Explain your reasoning.
Answer:
Diego
Step-by-step explanation:
divide 132 minutes by 44 pages and you get 3 pages per minute, then divide 140 minutes by 35 pages and you will get 4 pages per minute. so Diego reads 1 more page a minute than lin. hope i helped you :)
Aman, Anna and Tina are participating in the school race. Anna completes a lap in 120 minutes, Aman completes a lap in 240 minutes and Tina completes a lap in 60 minutes. If they all started at the same time, then after how long will they meet again?
Given:
Anna completes a lap in 120 minutes.
Aman completes a lap in 240 minutes
Tina completes a lap in 60 minutes.
To find:
The time after which they will meet again.
Solution:
They all started at the same time. So, the time after which they will meet again is the LCM of time taken by them to complete a lap.
Required time = LCM(120,240,60)
Factors of [tex]120 = 2\times 2\times 2\times 3\times 5[/tex]
Factors of [tex]240=2\times 2\times 2\times 2\times 3\times 5[/tex]
Factors of [tex]60=2\times 2\times 3\times 5[/tex]
So,
[tex]LCM(120,240,60)=2\times 2\times 2\times 2\times 3\times 5[/tex]
[tex]LCM(120,240,60)=240[/tex]
Therefore, after 240 minutes they will meet again.

To find slope, we need two points. Once we have them, we can put them into the formula:
[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] ← this is rise/run
For 7, it's just a matter of comparing any two consecutive points.
For 8, you are given the two points.
Carolyn has 20 biscuits in a tin.
She has
12 plain biscuits
5 chocolate biscuits
3 ginger biscuits
Carolyn takes at random two biscuits from the tin.
Work out the probability that the two biscuits were not the same type.
4 Marks
Answer:
Approximately 58.4%
Step-by-step explanation:
The probability that they are different is the opposite of the probability that they are the same.
The probability that they are the same is:
P(plain, plain) = (12/20) (11/19) = 132 / 380
P(chocolate, chocolate) = (5/20) (4/19) = 20 / 380
P(currant, currant) = (3/20) (2/19) = 6 / 380
P(same) = 132/380 + 20/380 + 6/380
P(same) = 158/380
P(same) = 79/190
Therefore, the probability that they are different is:
P(different) = 1 − 79/
[tex]\frac{111}{190}[/tex] is the probability that the two biscuits were of not the same type.
What is Probability?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
According to question, Carolyn has 20 biscuits in a tin.
She has 12 plain biscuits, 5 chocolate biscuits and 3 ginger biscuits
Carolyn takes at random two biscuits from the tin.
We have to find out the probability that the two biscuits were of not the same type.
P(plain biscuit, plain biscuit) [tex]=(\frac{12}{20} )(\frac{11}{19} )=\frac{132}{380}[/tex]
P(chocolate biscuit, chocolate biscuit)[tex]=(\frac{5}{20})(\frac{4}{19} )=\frac{20}{380}[/tex]
P(ginger biscuit, ginger biscuit)[tex]=(\frac{3}{20}) (\frac{2}{19})=\frac{6}{380}[/tex]
Probability of same type of biscuits
[tex]=\frac{132}{380} +\frac{20}{380}+\frac{6}{380}[/tex]
[tex]=\frac{79}{190}[/tex]
The probability that the two biscuits were not of the same type.
[tex]=1-\frac{79}{190}[/tex]
[tex]=\frac{111}{190}[/tex]
Hence, we can conclude that [tex]\frac{111}{190}[/tex] is the probability that the two biscuits were not of the same type.

Answer:
f(2) = -5
Step-by-step explanation:
For this problem, we are evaluating the graph of f(x), meaning at the value of x, we want the y-value.
Note, when x = 2 on the graph, the only y coordinate available is y = -5.
Hence, when we evaluate f(x) for x = 2, we get y = -5. f(2) = -5.

Why is 3^-2 not a negative number?
The rule you use is x^(-k) = 1/(x^k)
In this case x = 3 and k = 2, so,
3^(-2) = 1/(3^2) = 1/9
--------------------------------------------
One way to think of it, is to consider the equation below
3^2*3^x = 1
We can solve for x like this
3^2*3^x = 1
3^(2+x) = 1
3^(2+x) = 3^0
2+x = 0 .... the bases are equal, so the exponents must be equal
x = -2
meaning that
3^2*3^x = 1
updates to
3^2*3^(-2) = 1
Now isolate the 3^(-2)
3^2*3^(-2) = 1
3^(-2) = 1/(3^2)
3^(-2) = 1/9

3n - 5 = -8(6 + 5n)
Answer:
-1
Step-by-step explanation:
Original Equation:
3n - 5 = -8(6 + 5n)
Use distributive property on the parentheses.
-8 ⋅ 6 = -48
-8 ⋅ 5n = -40n
Equation now:
3n - 5 = -48 - 40n
Add 40n to both sides.
43n - 5 = -48
Add 5 to both sides.
43n = -43
Divide both sides by 43
n = -1

Please answer this it’s for a test and I suck in math I don’t even know how I’m in pre ap
Step-by-step explanation: To find this answer, you want to divide the amount of yards in half. This is the case since each string is 1/2. So as a result, each yard of whole string will produce 2 strings. To find your final answer, multiply 2 strings by 8 yards.
