If 8,a,b,27 are in geometric sequence, find the value of a and b.
Answer:
a = 12 and b = 18
Step-by-step explanation:
Given that,
8,a,b,27 are in geometric sequence.
For a GP, the nth term is given by :
[tex]a_n=ar^{n-1}[/tex]
Put n = 4
[tex]a_4=ar^{4-1}\\\\a_4=ar^3\\\\27=8\times r^3\\\\r^3=\dfrac{27}{8}\\\\r=\dfrac{3}{2}=1.5[/tex]
Put n = 2,
[tex]a_2=ar^{2-1}\\\\a=ar\\\\a=8\times 1.5\\\\a=12[/tex]
Put n = 3
[tex]a_3=ar^2\\\\=8\times 1.5^2\\\\b =18[/tex]
So, the values of a and b is 12 and 18 respectively.

Step-by-step explanation:
Kim took a 3,000 mile trip in 4 days.
1st day - 850 miles
2nd day - 745 miles
3rd day - 660 miles
How many miles did she travel the 4th day?
O A. 2265 miles
B. 745 miles
C. 855 miles
O D. 265 miles
E 755 miles
Answer:
B. 745 miles
Step-by-step explanation:
Given that
Kim took 3000 miles trip in 4 days
And,
1st day - 850 miles
2nd day - 745 miles
3rd day - 660 miles
We need to find out that how much she travel in the 4th day
So, it is
= 3000 miles - 850 miles - 745 miles - 660 miles
= 745 miles
Hence, the option b is correct
Consider the following discrete time process: at integer times, a marble arrives which can be one of m colors. Each color is equally likely; all events at different times are independent. As each marble arrives, it is placed into a bowl Unless there is a marble of that color already in the bowl. Then, that marble is removed from the bowl and the new marble does not go into the bowl. (The pair is placed in a separate bin for shipping). Let Gn denote the number of marbles currently in the bowl after the nth marble arrives. Compute,(a) the expectation E(Gn).(b) limn→[infinity] E(Gn).
Answer:
Below are the responses to the given question:
Step-by-step explanation:
Let X become the random marble variable & g have been any function.
Now.
For point a:
When X is discreet, the g(X) expectation is defined as follows
Then there will be a change of position.
E[g(X)] = X x∈X g(x)f(x)
If f is X and X's mass likelihood function support X.
For point b:
When X is continuing the g(X) expectations is calculated as, E[g(X)] = Z ∞ −∞ g(x)f(x) dx, where f is the X transportation distances of probability.If E(X) = −∞ or E(X) = ∞ (i.e., E(|X|) = ∞), they say it has nothing to expect from EX is occasionally written to stress that a specific probability distribution X is expected.Its expectation is given in the form of,E[g(X)] = Z x −∞ g(x) dF(x). , sometimes for the continuous random vary (x). Here F(x) is X's distributed feature. The anticipation operator bears the lineage of comprehensive & integral features. The superposition principle shows in detail how expectation maintains equality and is a skill.

A chicken farmer can produce one crate of eggs at a cost of $9.86, and can sell that crate for $34.24. If the farmer has a starting overhead cost of $7,312, not including production costs, how many crates must be sold in order to realize a profit of $11,300, to the nearest crate?
a.
164
b.
330
c.
463
d.
763
Answer:
The answer is D 763.
Step-by-step explanation:
Don't have an explanation
A chicken farmer needs to sell 763 crates to realize a profit of $11,300.
Equation
A statement of equivalence between two expressions containing variables and/or numbers is called an equation. In essence, equations are questions, and attempts to discover systematic answers to those questions have spurred the development of mathematics.
Equation according to the given information
Based on the given information describe the problem is equation.
(34.24 × x) - (7312 + 9.86x) = 11300
34.24x - 7312 - 9.86x = 11300
34.24x - 9.86x = 11300 + 7312
24.38x = 18612
x = 18612 / 24.38
x = 763
Hence chicken farmers need to sell 763 crate

Find the number of distinguishable permutations of the letters PEPPERONI. NO LINKS!!!!
This is is one value (and not two values separated by a comma) and it's slightly over 30 thousand.
========================================================
Explanation:
There are n = 9 letters in the word "PEPPERONI"
If we could tell all the letters apart, there would be 9! = 9*8*7*6*5*4*3*2*1 = 362,880 permutations, and that would be the answer.
However, we have repeated letters that we cannot tell apart. The P shows up a = 3 times, and the E shows up b = 2 times. So we need to divide by a!*b! = 3!*2! = 6*2 = 12 to correct for the overcounting. That leads to the final answer of (362,880)/(12) = 30,240

The answer is 77.27%
Step-by-step explanation:
Please mark brainliest!
Enjoy the rest of your day!
Answer:
77.2727.. (repeating)%
or 77 3/11 %
Although im not sure if fractions are accepted in percents, so stick to the first option
Step-by-step explanation:
A percent is simply [tex]\frac{}{100}[/tex]
How many 22's are there in 100? 100/22=4.54 repeating
So 22*4.54 repeating = 100
do the same to both sides of the equation
17 / 22
17*4.54 repeating
77.27272.../100
so 77.27272727... %

What is the distance from 33, 5) to (3 7.-1
Answer:
7.211
Step-by-step explanation:
I'm going to assume that's supposed to say (33, 5) to (37, -1)
Use the pythagorean theorem: a^2 + b^2 = c^2
"a" is going to be your difference in x values (37 - 33) = 4
"b" is going to be your difference in y values (5 - (-1)) = 6
4^2 + 6^2 = c^2
16 + 36 = c^2
52 = c^2
sqrt(52) = c
7.211 = c

Select the correct answer.
Esther works for a marketing company. She earns $12 per hour, and she gets a $50 travel allowance every month. Which linear equation could be used to find her monthly pay rate?
A. y = 50x + 12
B. y = 12x + 50
C. y = 12x
D. y = 50x
The linear equation that could be used to find her monthly pay rate will be y = 12x + 50.
What is a linear equation?It is referred to as the relationship between two variables, and a straight line is produced when the linear equation's graph is shown. The equation is referred to as a linear equation in one variable if just one variable is contained in the linear equation.
It is given that, Esther is employed by a marketing firm. She makes $12 per hour and receives a $50 monthly travel reimbursement.
Suppose x be the number of months,
The linear equation could be used to find her monthly pay rate is,
Total amount = Amount per hour×number of hour+ travel allowance
y = 12x + 50
Thus, the obtained linear equation for a given condition will be y = 12x + 50.

9514 1404 393
Answer:
B) 171 units^2
Step-by-step explanation:
The area is given by the formula ...
A = 1/2(b1 +b2)h
Filling in the given base and height values, we find the area to be ...
A = 1/2(23 +15)(9) = (19)(9) = 171 . . . square units
_____
Additional comment
You can select the correct answer choice simply on the basis of "reasonableness." If this were a 9×15 rectangle, its area would be 9×15 = 135 square units, more than 85.5. You know its area is less than a 9×23 rectangle, so is less than 9×23 = 207 square units. Only one answer choice is a value between 135 and 207.

Multiplication by 9 is not so hard. It is multiplication by 10-1:
15×9 = 15×(10 -1) = 150 -15 = 135
