Answer:
The right answer is A. AA Postulate
If m and n are whole numbers such that m^n = 121, then find the value of (m-1)^n+1.
Because m and n are whole numbers, we only have 3 values for m, and 3 values for n :
[tex]1^{121} ; 11^{11} ;121^{1}[/tex] (or you can say because 121 only have the factors of 1 ; 11 ; 121, those are the only possible values for m and n, then conclude the possible values)
Now, we will substitute them in :
If m = 1 ; n = 121
[tex](1-1)^{121+1}[/tex] = 0
If m = 11 ; n = 11
[tex](11-1)^{11+1}[/tex] = 1000000000000
If m = 121 ; n = 1
[tex](121-1)^{1+1}[/tex] = 14400

lnx=-3
the answer in the textbook says it becomes x=e^-3 which I agree with, but then it gives 0.05 as the answer to solving it, I just don't understand how they found 0.05. Can anyone explain how to get 0.05 from x=e^-3?
Answer:
because It's rounded to the nearest hundred place
Step-by-step explanation:
Given equation:
[tex] \ln(x ) = - 3[/tex]recall that,
[tex] \ln(a ) = b \iff {e}^{b} = a[/tex]
remember, In is natural logarithm which is actually nothing but common logarithm with the base euler's number (e) . anyway rewriting lnx=-3 yields:
[tex] \ln( x ) = - 3\\ \iff {e}^{ - 3} = \frac{1}{ {e}^{3} } [/tex]
1/e³ is approximately 0.0497870684..... , rounding it to the nearest hundred place would be 0.05 which is the same answer as your textbook .

Patti puts 40 marbles in a bag. Each marble has a mass of 3 grams. What is the total mass of the bag of marbles? Show work
Answer:
120 grams
Step-by-step explanation:
Since each marble has a mass of 3 grams and there are 40 marbles, simply multiply 40 * 3 which is 120 grams.
The probability of obtaining a head when a certain coin is flipped is about 0. 65. Which of the following is closest to the probability that heads would be obtained 15 or fewer times when this coin is flipped 25 times?.
The probability that heads would be obtained 15 or fewer times when this coin is flipped 25 times is 0.370
How to determine the probability?The given parameters are:
Sample size, n = 25Probability of success, p = 0.65Number of success, x ≤ 15The probability is represented using the following binomial formula
[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x}[/tex]
Using the above formula, we have:
[tex]P(x \le 15) = 0.370[/tex]
Hence, the probability is 0.370

Answer:
13: 16
14: 6.28
15: √45
Step-by-step explanation:
13: Count the number of spaces from A to D or B to C, which is 4.
Then, count the number of spaces from A to B or C to D, which is also 4.
After that, multiply the two numbers. You should now have an answer of 16.
14: You want to find the diameter of the circle, which is 2.
Then, multiply 2 by 3.14, aka pi. You should now have an answer of 6.28.
*15: Count the number of spaces from A to C, which is 6.
Then, count the number of spaces from A to B, which is 3.
After that, square both of the numbers. 6 x 6 = 36 and 3 x 3 = 9.
Now, the final step. Add both numbers together. 36 + 9 = 45.
You should now have an answer of √45.
I hope this helped!

For each ordered pair, determine when weather it’s a solution to 7x -6y=19
Solutions:
(7,5)
(1,-2)
(-5,3)
(-4,0)
Options A and B
Solution:In order to determine whether or not an ordered pair is a solution to an equation, plug in the values of x and y:7x-6y=197(7)-6(5)=1949-30=1919=19We have a true statement. Therefore, the ordered pair is a solution to the equation 7x-6y=19.Let's try the other ordered pairs.7(1)-6(-2)=197+12=1919=19Here's another true statement.Let's check the remaining two options:7(-5)-6(3)=19-35-18=19-53≠19Here we have a false statement.7(-4)-6(0)=19-28-6=19-34≠19Therefore, the ordered pairs that make this equation true are (7,5) and (1,-2)Hope it helps.

The function f(x)=log2x is transformed 4 units down and vertically compressed by a factor of 0.2 to become g(x).
Which function represents the transformation g(x)?
The answer is: g(x)=15log2(x)−4
Using translation concepts, it is found that function g(x) is given by:
[tex]g(x) = \frac{1}{5}\log_{2}{x} - 4[/tex]
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, the parent function is given by:
[tex]f(x) = \log_{2}{x}[/tex]
It was shifted 4 units down, hence:
[tex]g(x) = \log_{2}{x} - 4[/tex]
It was vertically compressed by a factor of 0.2, hence:
[tex]g(x) = \frac{1}{5}\log_{2}{x} - 4[/tex]

Of the 1250 students registered at the local high school, 30% of them did not vote during the student body elections. How many students did not vote?
A) 350
B) 425
C) 365
D) 375
Answer: D) 375
Step-by-step explanation:
We will find 30% of 1,250 since 30% did not vote. A percent divided by 100 becomes a decimal.
30% / 100 = 0.3
1,250 * 0.3 = 375
D) 375 students did not vote.

Yesterday a car rental agency rented 4 convertibles and 30 other vehicles. Considering this data, how many of the first 68 vehicles rented today should you expect to be convertibles?
100 points and brainliest to answer
Answer:
8
Step-by-step explanation:
[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]
Given:
number of convertibles = 4total number of vehicles = 30 + 4 = 34[tex]\implies \sf P(convertible)=\dfrac{4}{34}=\dfrac{2}{17}[/tex]
To find the expected number of convertibles from the first 68 vehicles:
[tex]\begin{aligned}\implies \sf P(convertible) \times 68 & =\sf\dfrac{2}{17} \times 68\\\\ & = \sf8\end{aligned}[/tex]
Answer:
30 other vehicles + 4 convertibles = 34 cars
34 * 2 = 68
30 * 2 other vehicles + 4 * 2 convertibles = 68 cars
60 other vehicles and 8 convertibles
