Create an equivalent expression for 1.2 cubed over 1.3 raised to the fourth power all raised to the power of negative seven.
Group of answer choices
1.2 to the twenty-first power over 1.3 to the twenty-eighth power
1.3 to the twenty-eighth power over 1.2 to the twenty-first power
1.2 raised to the fourth power over 1.3 cubed
1.3 cubed over 1.2 raised to the fourth power
Answer:
1.3 to the twenty-eighth power over 1.2 to the twenty-first power
Step-by-step explanation:
The equivalent expression for 1.2 cubed over 1.3 raised to the fourth power all raised to the power of negative seven is 1.3 cubed over 1.2 raised to the fourth power.
To find the equivalent expression, we need to use the rule that x^a / x^b = x^(a-b) for any value of x except 0.
In this case, we have 1.2^3 / 1.3^4 raised to the power of -7. Applying the rule, we get:
(1.2^3 / 1.3^4)^-7 = (1.2^(-4) / 1.3^3)^7
Since the exponent of a number raised to a power is the same as the power, we can rewrite the expression as:
1.2^(-47) / 1.3^(37)
Simplifying, we get:
1.2^(-28) / 1.3^(21)
Which is the same as:
1.3^(21) / 1.2^(28)
This is the same as the expression 1.3 cubed over 1.2 raised to the fourth power. Therefore, the equivalent expression for 1.2 cubed over 1.3 raised to the fourth power all raised to the power of negative seven is 1.3 cubed over 1.2 raised to the fourth power.

The amount deposited at each rate is 7,700 if the total annual interest income is $2030
What is annual interest income?
The compensation received by an entity for lending its money or allowing another organization to utilize it is known as interest income. The amount that an investor's money invested in a project or venture earns is referred to as interest income on a bigger scale.
Here, we
Let x = the amount invested at 4.5%.
let y = the amount invested at 5.0%.
Total interest is $2030
Equation becomes:
.045*x + .05*y = 2030.....(1)
y = 2 x,
so we can replace y with 2x and your equation becomes:
.045*x + .05*2*x = 2030
factor out the x to get x * (.045 + .05*2) = 2030
simplify and combine like terms to get
.145 * x = 2030
solve for x to get x = 14,000
2x is therefore equal to 28,000.
she has 14,000 invested at 4.5% and
28,000 invested at 5%.
Now, put the value of x and y in equation (1), and we get
.045*14,000 + .05*28,000 = 7,700
Hence, the amount deposited at each rate is 7,700 if the total annual interest income is $2030.

A mining company owns two mines. These mines produce an ore that can be graded into two classes: regular grade and low grade. The company must produce at least 350 tons of regular-grade and 610 tons of low-grade ore per week. The first mine produces 5 tons of regular-grade and 17 tons of low-grade ore per hour. The second mine produces 20 tons of regular-grade and 10 tons of low-grade ore per hour. The operating cost of the first mine is $7000 per hour, and the operating cost of the second mine is $29,000 per hour. The first mine can be operated no more than 54 hours a week, and the second mine can be operated no more than 27 hours a week. How many hours per week should each mine be operated to minimize the cost?
The number of hours to operate the mines to minimize cost are Mine 1 hour = 30 hours and Mine 2 hour = 10 hours
How to determine the number of hours?The given parameters can be represented using the following table of values
Mine 1 (x) Mine 2 (y) Available
Regular grade 5 20 350
Low grade 17 10 610
Operating cost 7000 29000
Time 54 27
From the table, we understand that we are to minimize cost
This means that:
Objective function: C = 7000x + 29000y
Subject to:
5x + 20y ≥ 350
17x + 10y ≥ 610
Next, we plot the constraints on a graph (see attachment)
From the graph, we have
(x, y) = (30, 10)
This means that
Mine 1 hour = 30 hours
Mine 2 hour = 10 hours
Hence, the number of hours are 30 and 10 hours

Stephanie baked a cake and cut it
into 15 equal pieces. She put icing
on 9 pieces. Tammy baked the same
size cake and cut her cake into 5
equal pieces. How many pieces of
cake should Tammy put icing on so
that it is equivalent to the amount
of icing on Stephanie's cake?
Answer: 3 pieces
Step-by-step explanation:
This problem can be solved by modeling the problem using equivalent fractions.
We know Stephanie put icing on 9 of her 15 pieces, this gives us a fraction of [tex]\frac{9}{15}[/tex].
Tammy cut her cake in 5 pieces, but we do not know how many were iced, the pieces of iced cake will be our variable, x, so her fraction is [tex]\frac{x}{5}[/tex].
Both of the fractions need to be equivalent so [tex]\frac{9}{15} =\frac{x}{5}[/tex], which can be solved for x = 3 pieces.

Mathematical arithmetic is the study of the properties of the standard operations on numbers, such as addi - tion, subtraction, multiplication, division, exponents, and root extraction. The Peano axioms, developed by the Italian mathematician Giuseppe Peano in the 19th century and still vital to the modern study of mathematical logic, formalised arithmetic. There are only a few ancient artefacts that can be used to date the invention of addition and subtraction.

Using the formula of test statistic, the value of the test statistic is 2.6961.
The mean of the public accountant is
Mean x(p) =50.2+59.8+57.3+59.2+53.2+56.0+49.9+58.5+56.0+51.9/10
x(p) = 55.2
Now the standard deviation of public accountant is
SD(p) = √{∑(x-x(p))^2/n-1}
SD(p) = √(50.2-55.2)^2+(59.8-55.2)^2+..................+(51.9-55.2)^2/n-1
After solving;
SD(p) = 3.34
The mean of the financial planner is

let x be a random variable with c.dj. f(x). find the c.d.f. of ax b first for a > 0, then for a < o.
The cumulative distribution function, for
a > 0 is F((x - b)/a) and for a < 0 is 1 - F((x - b)/a).
What is cumulative distribution function?
The cumulative distribution function of a real-valued random variable X, or simply the distribution function of X, evaluated at x, is the probability that X will take a value less than or equal to x in probability theory and statistics.
We have to find the c.d.f of ax + b for a > 0 and a < 0.
F(x) = P(X < x)
a>0:
P(aX + b < x) = P(aX < (x - b)) = P(X < (x - b)/a) = F((x - b)/a)
a < 0 :
P(aX + b < x) = P(aX < (x - b)) = P(X > (x - b)/a) = 1 - P(X < (x - b)/a) =
1 - F((x - b)/a).
Hence, the cumulative distribution function, for
a > 0 is F((x - b)/a) and for a < 0 is 1 - F((x - b)/a).

Given,
Here we need to find the prime number that is not in the set, if if the sum of a set of ten different positive prime numbers is an even number.
Here we know that, all prime numbers except the first prime number are odd except 2.
And here we assume that the two prime numbers are different,
So, if one of the prime number is 2 which is even, the other prime number would be odd and hence sum of the prime numbers would be odd as sum of an even and an odd number is always odd.
Where as if none of the prime numbers are odd, then both the prime numbers would be odd and hence sum of the prime numbers would be even as sum of two odd numbers is always even.
There the correct option is A. 2.
