The expression that is similar to [tex]\frac{2^{3} . 2^{4} }{2^{12} }[/tex] is [tex]\frac{1}{2^{5} }[/tex]
What is indices?Index (indices) in Maths is the power or exponent which is raised to a number or a variable. For example, in number [tex]2^{4}[/tex], 4 is the index of 2. The plural form of index is indices. In algebra, we come across constants and variables. The constant is a value which cannot be changed.
In the expression [tex]\frac{2^{3} . 2^{4} }{2^{12} }[/tex] all the indices have a common base 2
From numerator [tex]2^{3}[/tex] x [tex]2^{4}[/tex] = [tex]2^{3 + 4}[/tex] which [tex]2^{7}[/tex]
so since the base at the numerator is same as that at the denominator we subtract their exponents
so that we have,
[tex]2^{7 - 12}[/tex] = [tex]2^{-5}[/tex]
which can further be written as [tex]\frac{1}{2^{5} }[/tex]
In conclusion the simplified form of the expression is [tex]\frac{1}{2^{5} }[/tex]

Answer:
315 minutes
It takes 15 minutes for 1 bracelet. 15 minutes multiplied by 21 bracelets is 315. Lmk if you need more help
Answer: 315 minutes.
Step-by-step explanation:
To solve this, we need to find out how long it takes to make one bracelet first.
If it takes 45 minutes to make 3 bracelets, we need to divide 45 by 3, which gives us 15.
This means it takes 15 minutes to make one bracelet.
Now, we need to multiply 15 by 21.
15 x 21 = 315.
This means it will take 315 minutes to make 21 bracelets.

You deposit $2000 each year into an account earning 5% interest compounded annually. How much will you have in the account in 30 years?
There will be amount of $8,880.43 in the account in 30 years.
What is compound interest?
Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.
Let A be the final amount.
Principal = $2000
r = rate = 5%
n = number of compounding in a year = 4
t = number of years the principal will be compounded = 30
The formula for compound interest:
[tex]A=P(1 +\frac{r}{n})^{nt}[/tex]
[tex]A=2000(1 +\frac{0.05}{4})^{4 \times 30}[/tex]
A = $8,880.43
I will have $8,880.43 in the account in 30 years.

There are 35 tickets in a bag and the ratio of winning tickets to losing tickets is 1 to 4. How many of each kind of ticket are in the
bag?
Number of winning tickets =7 and Number of losing tickets = 28. When there are 35 tickets in a bag and the ratio of winning tickets to losing tickets is 1:4
What is ratio?Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings. For instance, a class has a 12:15 boy-to-girl ratio, whereas the part-to-whole ratio refers to the relationship between a particular group and the entire. For instance, five out of every ten people enjoy reading. As a result, the ratio of the part to the whole is 5: 10, meaning that 5 out of every 10 persons enjoy reading.Given: Total tickets = 35
The ratio of winning tickets to losing tickets = 1:4
Number of winning tickets = [tex]\frac{1}{1+4} *35[/tex]
[tex]\frac{1}{5} *35=7[/tex]
Number of losing tickets = [tex]\frac{4}{1+4} *35[/tex]
[tex]\frac{4}{5} *35[/tex]
4×7=28
Hence, Number of winning tickets =7 and Number of losing tickets = 28.

(11 - 2i) - (9 - 8i)
Find the value of X. The diagram is not to scale.
The value of x is given by 13.
The above angle of the triangle is vertically opposite to the angle 110.
So, the above not mentioned angle of triangle is = 110.
We know from Angle sum property of a triangle that the sum of all interior angles of a triangle is 180.
So, from the given figure we can write that,
110 + 57 + x = 180
167 + x = 180
x = 180-167
x = 13
Hence the value is, x=13.

What is arithmetic progression?
The difference between two successive words in an arithmetic progression sequence, often known as A.P., is always the same. The common difference is the term for the constant. It is a technique for calculation that has been used for centuries to get precise results for everyday calculations such as measurements, labelling, and other kinds of everyday calculations. The word "arithmos" in Greek, which simply means "numbers," is where the phrase first appeared.What is Geometric progression?
When one term is varied by another by a common ratio, the series is referred to as a geometric progression or sequence. When we multiply the previous term by a constant (which is non-zero), we get the following term in the sequence.The difference of these numbers is 6, so the next two terms of an arithmetic sequence would be 8+6 = 14, and 14+6 = 20.
The ratio of these numbers is 4, so the next two terms of a geometric sequence would be 8×4 = 32, and 32×4 = 128.
Any pair of numbers can be used that is not (14, 20) or (32, 128).
The next two terms could be 0 and 1, or they could be 14 and 32.

Inverse variation equation:
y = k/x, where k- constant of variationGiven x = 13, y = - 3Find the value of k- 3 = k/13k = - 3*13k = - 39The equation is:
y = - 39/xAnswer:
y = -39/x
Step-by-step explanation:
Formula we use,
→ y = k/x
→ k = xy
Now the value of k will be,
→ k = xy
→ k = 13 × (-3)

→ [ y = -39/x ]
Hence, the answer is y = -39/x.
What is 2 sigma confidence interval?
Step-by-step explanation:
A two sigma confidence interval is created whenever our alternate hypothesis does not equal a value.
For example if
[tex]h_{o} = 0.36[/tex]
and
[tex]h _{a} ≠0.36[/tex]
We used a two sigma confidence interval because we are thinking a portion is either below 0.36 or above 0.36.
When solving these probability for the p value, multiply the inital result by 2 to get the p value
The 2 sigma confidence interval is a principle that states that a result will be considered significant if 95% of the population is two standards deviation from the average value.
What is the 2-sigma confidence interval?The two-sigma confidence level states that 95% of the values obtained in the results from a population should be within2 deviations from the mean. Anything below this acceptable percentage is not considered the 2-sigma confidence level.
If 68% of the score are within 1 standard deviation from the mean, then that will be considered the 1-sigma rule. If 99.7% of the score is 3 standard deviations from the mean then we can refer to that as the 3-sigma confidence interval.

beginning repayment of the loan in 4.5 years. He also knows that during this non-payment
period, interest will accrue at 4.29%. (Round all monthly payment calculations to 2 decimal
places.)
a. How much interest will Rodrigo accrue during the 4.5-year non-payment period?
b. If Rodrigo decides to make no payments during the 4.5 years, the interest will be
capitalized at the end of that period. What will the new principal be when he begins
making loan payments?
How much interest will he pay over the life of the loan?
c. Suppose Rodrigo only paid the interest during his 4 years in school and the 6-month
grace period. What will he now pay in interest over the term of his loan?
Rodrigo will accrue 1023.17 interest during the 4.5-year non-payment period.
Define interest.The simplest way to compute interest is as a percentage of the principal. For instance, if you agreed to borrow $100 from a buddy with 5% interest, the interest you would pay would only be 5% of $100: $100(0.05) = $5. Simple Interest (S.I.) is a way for figuring out how much interest will accrue on a specific principal sum of money at a certain rate of interest. For instance, if someone borrows Rs. 5000 at a rate of 10 p.a. for two years, they will pay S.I. on the borrowed money for those two years.
Given,
For calculating interest:
Interest = Principal ×rate × time
Principal = 5300
Rate = 0.0429
Time = 4.5
Interest = 5300 × 0.0429 × 4.5
Interest = 1023.17
