Mathematical objects other than numbers can be used in operations. Here, t can be expressed as  [tex]\frac{Q-M}{r}[/tex].

Binary and unary operations are the two most popular forms of operations. Trigonometric functions and negation are examples of unary operations that use only one value. Contrarily, binary operations, which include addition, subtraction, multiplication, division, and exponentiation, only accept two values.

Mathematical objects other than numbers can be used in operations. Logic operations like and, or, and not can be used to combine the logical values true and false. It is possible to add and subtract vectors. Utilizing the function composition operation, it is possible to combine rotations by first performing the first rotation and then the second. The binary operations union and intersection as well as the unary operation of complementation are operations on sets. Composition and convolution are two operations on functions.

Solving for t,

Q = M + Mrt

t = [tex]\frac{Q-M}{r}[/tex]

Second option is correct

44% is the percentage of non response

What is population and sample?

Population is the entire set of items from where the data is drawn for statistical study

A random selection of members of the population is known as sample.

Here

Number of business chosen at random = 50

Number of questionnaire returned by mail = 28

Number of non responses = 50 - 28

                                            = 22

Since the committee plans to survey local businesses about the importance of students as customers, the population is all about local business.

Since the specific group from the population are 50 local businesses chosen by the committee, sample is the 50 to whom the questionnaire was sent

Percentage of non response = [tex]\frac{22}{50} \times 100[/tex]

Answer:

Choice C
==> Bank A

Step-by-step explanation:

Principal P = $2000

Bank A calculation

Simple Interest at 5% for 4 years  = Prt = 2000 x 5/100 x 4 = $400

Bank B Calculation

At 4% interest compounded quarterly, the accrued value(Principal + Interest) is given by the formula:

[tex]A = P(1 + r/n)^{nt}[/tex]

where

P = principal

r = annual interest rate as percentage

n = number of compounding per year

t = number of years

We have r = 4/ 100 = 0.04

n = 4 since interest is computed quarterly or 4 times a year

t = 4 years

[tex]A = 2000 ( 1 + 0.04/4)^{(4) \cdot (4)}\\\\A = 2000 (1.01)^{16} = \$2,345.16\\\\\text{Interest } = 2345.16 - 2000 = $345.16[/tex]

Since interest earned at bank A (400) > interest earned at bank B(345.16), the answer would be C.   ==> Bank A

The values of the function given by the graph are:

If we have a function [Equation] it would look something like this:

3x+y=4

In order to solve for both values and graph it [If that's what you are trying to do], you solve for y and then replace values [Of your own choosing, or they are given to be studyed] in x, after we replace the values in x, we are going to have the respective value of y.

From our previous example, it would be:

y = -3x+4

So, when we start replacing the values of X, we will get the respective values for Y, let's try doing it from -3 to 3.

x = -3 => y = -3(-3)+4 => y = 13

x = -2 => y = -3(-2)+4 => y = 10

x = -1 => y = -3(-1)+4 ) => y = 7

x = 0 => y = -3(0)+4 => y = 4

x = 1 => y = -3(1)+4 => y = 1

x = 2 => y = -3(2)+4 => y = -2

x = 2 => y = -3(3)+4 => y = -5

From this, we would end up with the following points:

System of Equations

[tex]\boxed{x + y = 3600}[/tex]

[tex]\boxed{0.04x + 0.06y = 178}[/tex]

Step-by-step explanation:

Given information:

Define the variables:

Convert the percentages into decimal form:

[tex]\implies \sf 4\%=\dfrac{4}{100}=0.04[/tex]

[tex]\implies \sf 6\%=\dfrac{6}{100}=0.06[/tex]

Therefore, the system of equations that could be used to determine the dollar amount of phone sales and computer sales is:

[tex]\begin{cases}x + y = 3600\\0.04x + 0.06y = 178\end{cases}[/tex]

Solving the system of equations

Rewrite the first equation to isolate y:

[tex]\implies x=3600-y[/tex]

Substitute the expression for x into the second equation and solve for y:

[tex]\implies 0.04(3600-y)+0.06y=178[/tex]

[tex]\implies 144-0.04y+0.06y=178[/tex]

[tex]\implies 144+0.02y=178[/tex]

[tex]\implies 0.02y=34[/tex]

[tex]\implies y=1700[/tex]

Therefore, Cameron made $1,700 of computer sales.

Substitute the found value of y into the first equation and solve for x:

[tex]\implies x+1700=3600[/tex]

[tex]\implies x=1900[/tex]

Therefore, Cameron made $1,900 of phone sales.

Answer:

Step-by-step explanation:

Plug in the value of x into the expression [tex]6x^2-4[/tex].

Formula for arc length when the angle is in degrees:

r = radius = 6 in

θ= 60 degrees

60 + 0.04 = 60.04

The answer is 60.04

Since a right triangle is formed, the radius of the cross-section is the missing side of the triangle.

Apply the Pythagorean theorem:

C^2 = a^2 + b^2

Where:

c = hypotenuse = 5

a & b = the other 2 legs of the triangle = 4 and x

Replacing:

5^2 = 4^2 + x^2

solve for x ( radius of the cross-section)

25 = 16 + x^2

25-16 = x^2

9 = x^2

√9 = x

x = 3 cm

From the Latin word "per centum," which meaning "by the hundred," the word "percentage" was borrowed. The denominator of percent's is 100, making them fractions. In other words, it is the relationship between a component and a whole in which the value of the entire is consistently set to 100. The value of the entire is always 100 in a percentage, which is a ratio or fraction. Sam, for instance, would have received a score of 30 out of 100 on his arithmetic test if he received a 30%. When expressed as a ratio, it is written as 030:10 and as a fraction, 30/100. An quantity or part that is contained in each hundred is known as a percentage. The symbol "%" signifies that it is a fraction with 100 as the denominator.

35 h * 1 / 5 = 7 h

35 h * 1 / 2 = 17.5 h

35 h * 1 / 7 = 5 h

7 h + 17.5 h + 5 h

= 29.5 h

The rest of his time = 35 - 29.5

= 5.5 h

5.5 / 35 = 0.15714
