Answer:
a) is -7
Step-by-step explanation:
8=2048\((2)^{n-1}\)
\(\frac{8}{2048} =\frac{2048^{n-1} }{2048}\)
8/2048=0.00390625 = \((2)^{n-1}\)
\(2^{-8}\) = 0.00390625
-8-1=-7
and do the rest with the same equation which is tn=a\(r^{n-1}\)

lol i need a refresh when you multiply the fraction to get it to be added with the other one do you multiply the whole number too?
Answer:
-81/3+32/5
-81×5+32×3/15
-243+96/15
-147/15
-49/5 Ans
To answer your question ("do you multiply the whole number too?"): Yes, you have to multiply the whole number as well. You can't just separate 1/3 from -8 and multiply it with 2/5, because the whole number is part of the mixed #. Whenever you multiply, add, divide, subtract, or do anything to two mixed numbers, you must include the whole term.
- - - - - - - - - -
Now your question is addition. Like I said, when you add them together, the whole number and the fractions count as one term.
So basically, -8 1/3 + 3 2/5...
- - - - - - - - - -
1) Find the LCM (least common multiple) of the denominators
The LCM of 3 and 5 is 15. To get from 3 to 15, you have to multiply 3 by 5. Now multiply the numbers of the fraction part only by 5.
1/3 --> 5/15 (as you can see, 1x5 = 5, 3x5 = 15)
Now for 2/5: To get from 5 to 15, multiply 5 by 3. Do the same thing to the numbers in the fraction
2/5 --> 6/15 (2x3 = 6, 5x3 = 15)
***TO CLARIFY, DO NOT MULTIPLY THE WHOLE TERM BY THE NUMBER***
Right: 2x3 = 6, 5x3 = 15, 6/15
Wrong: 2/5 x 5 = 2
- - - - - - - - - -
2) So now that we found a common denominator, change the two terms to -8 5/15 + 3 6/15 (because we had to find the LCM to make life a lot easier)
- - - - - - - - - -
3) We just add them together. Even though they are a term together, you can split them apart and add them together separately thanks to the commutative property of addition*.
Time to split it apart to make life a whole lot easier. -8 5/15 can be split apart into the two terms -8 and 5/15. For 3 6/15, it can be split into 3 and 5/15.
Two options from here on:
Set up a single equation: Put all the terms into one equation. -8 + 3 + 5/15 + 6/15. Solve by adding all the terms together in whichever order you prefer (again, thanks to the commutative property of addition)
It would result in the answer -4 4/15
Or...
Set up two separate equations: Set up an equation for whole numbers, and another one for fractions.
Equation 1: -8 + 3 = -5
Equation 2: 5/15 + 6/15 = 11/15
(6 + 5 = 11)
And we add the sums together. -5 + 11/15 = -4 4/15
And that's it!
- - - - - - - - - -
*Commutative Property of Addition: The sum of the numbers will NOT change even if you change the order of the addends

Tim incorrectly rewrote the expression 1/2p - (1/4p + 4) as 1/2p + 1/2p - 4. Rewrite the expression without parentheses. What was Tim's error?
Answer:
1/2p - 1/4p - 4.
Step-by-step explanation:
1/2p - (1/4p + 4)
= 12p - 1/4p - 4
≠ 1/2p + 1/2p - 4
Instead of writing -1/4p, Tim wrote 1/2p

Hence, 70 people out of 100 who had attained the previous year
Step-by-step explanation:
If this is completely proportional, you'd make the formula
\( \frac{420}{600} = \frac{x}{100} \)
Cross multiply
\(42000 = 600x\)
Then we just divide by 600
\(x = 70\)

Michael has a bag of marbles. The frequency of selecting each color is recorded in the table below. Outcome Frequency Green 4 Black 6 Orange 5 Based on the given frequency, determine the experimental probability of selecting a black marble. 0.27 0.33 0.40 0.60
help asap if answer is correct and provided explanation i will give brainiest.
Reason:
6 black out of 4+6+5 = 15 total
6/15 = 0.40 is the experimental probability of selecting black.
Side note: The term "empirical probability" is the same as "experimental probability".
The experimental probability of selecting a black marble will be 0.40. The correct option is C.
What is probability?Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favourable outcomes to all outcomes.
Probability = Number of favourable outcomes / Number of samples
Given that Michael has a bag of marbles. The frequency of selecting each colour is recorded in the table below. Outcome Frequency Green 4 Black 6 Orange 5.
Number of favourable outcomes = 6
Number of samples = 4+6+5 = 15
Probability = Number of favourable outcomes / Number of samples
Probability = 6 / 15
Probability = 0.40
Therefore, the probability will be 0.40.

Yolanda participated in a walkathon in which each kilometer walked raised $10 for charity. Her goal was to raise more than $300 on Saturday and Sunday. She raised $50 on Saturday. Which graph shows all the distances, in kilometers, that Yolanda could have walked on Sunday to reach her goal?
Answer:
B
Step-by-step explanation:
She needed to raise at least $250
$250 divided by $10 equals 25 km
So she need more than 25km to raise over $300
The base of a cone shaped glass is 12 inches and it is 18 inches tall. You fill the glass with soda pop to the top of the glass. What is the volume of soda pop???
Answer:
To find the volume of a cone, use the equation: V = 1/3Bh.
In this equation, V is the volume, B is the base, and h is the height.
We are given that the base is 12 inches, and the height is 18 inches. With those necessary values, we can substitute those values, and calculate it.
V = 1/3(12)(18)
V = 4(18)
V = 72.0
Therefore, the volume of this glass is 72.0 cubic inches.

(11,122)
2) Find the slope (change in y divided by change in x).
Slope = (122-82) / (11-7) = 40/4 = 10
3) Pick one of the points and insert it into point slope form.
y - 82 = 10(x-7)

Karim multiplies two numbers written in scientific notation and finds that the product is 0.0258 × \(10^{-8 }\)
Explain the next steps Karim should take to solve this problem. Be specific.
Answer:
To solve the problem, Karim can follow these specific steps:
Understand scientific notation: Ensure that Karim understands the basic concept of scientific notation, which represents numbers as a product of a decimal number between 1 and 10 and a power of 10. For example, 0.0258 × 10^-8 is in scientific notation.
Convert to standard notation: Karim should convert the given numbers in scientific notation to standard notation. In this case, he can multiply 0.0258 by 10 raised to the power of -8. The result will be a decimal number in standard notation.
Perform the multiplication: Multiply the two numbers without considering the scientific notation. Multiply 0.0258 by 10 raised to the power of -8. This will give the actual product of the two numbers in standard notation.
Adjust the answer to scientific notation: After performing the multiplication, Karim should evaluate the result and adjust it to scientific notation if necessary. If the result is a very small or very large number, it is often expressed in scientific notation for convenience.
Finalize the answer: Write down the final answer in scientific notation, if applicable. Make sure to include the decimal number between 1 and 10 and the corresponding power of 10.
By following these steps, Karim will be able to solve the problem and obtain the accurate result in scientific notation, if necessary.

What fraction represents the percentage of their budget that is designated for utilities and food?
The fraction represents the percentage of their budget that is designated for utilities and food is 17/50.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
The circle graph below shows the Johnson family budget for one month.
Then the fraction represents the percentage of their budget that is designated for utilities and food will be
