What is the error in this equation for a trigonometric ratio? Explain the error in full sentences and give a corrected ratio. (5 points)

Answers

Answer 1

Answer:

[tex]\cos\ A = \frac{2}{4.5}[/tex]

Step-by-step explanation:

Given

[tex]sin\ A = \frac{2}{4.5}[/tex]

See attachment

Required

Explain and correct the error

The error in the equation is that: the formula of cosine of angle A is used to calculate the sine of angle A.

The ratio can be corrected as by using:

[tex]\cos\ A = \frac{Adjacent}{Hypotenuse}[/tex]

[tex]\cos\ A = \frac{AC}{AB}[/tex]

[tex]\cos\ A = \frac{2}{4.5}[/tex]

Dean's class collected signatures for a petition. By the end, 7 students had collected: 8 signatures 5 signatures 7 signatures 5 signatures 6 signatures 5 signatures 6 signatures What was the mean number of signatures collected? signatures Submit.​

Answers

The answer is 6 because in order to find the mean you add all the numbers up
8+5+7+5+6+5+6=42
Then you divid 42 by the number of students which is 7

42 divided by 7 is 6

So the answer would be 6 is the mean number

Answers

Answer:

6

Explanation:

the sum of all four angles in a quadrilateral is 360°. thus, to find the angle ∠JML, we need to subtract the values of the other angles from 360° as such:

360° - 66° - 74° - 110° = 110°

the total value of angle ∠JML is 110°.

now, since ∠JML is equal to 17x + 8, we can subtract 8° from 110° to get 102°. following that, we can divide 102° by 17 which yields us the result of 6. hence, we now know that x = 6.

Answer:

Step-by-step explanation:

The division of 15 divided by 4 gives the quotient is 3.

What is Division?

Division is one of the four fundamental mathematical operations, along with addition, subtraction, and multiplication. Division is described as the separating of a large group into smaller groups so that each group has an equal number of things.

We have to divide 15 by 4.

So, the division is

                            4 | 15 | 3

                                 12

                              ____

                                  3

Thus, the quotient is 3.

why is 2 × 3/4 less than 2​

Answers

Answer:

becuase 2*3 is 6, and 2*4 is 8, and when you simplfy it is 1 and 1/2, which in decimal form is 1.5, making it less than 2

Answer:

Is 2/4 smaller than 2/3? These are the same questions with one answer.

To get the answer, we first convert each fraction into decimal numbers. We do this by dividing the numerator by the denominator for each fraction as illustrated below:

2/4 = 0.5

2/3 = 0.667

Then, we compare the two decimal numbers to get the answer.

0.5 is less than 0.667.

Therefore, 2/4 is less than 2/3 and the answer to the question "Is 2/4 less than 2/3?" is yes.

The answer is C: the ranges of g(x) and f(x) are the same, and their domains are also the same.

Step-by-step explanation:

Just took the test on edge!! :)

Option C The ranges of g(x) and f(x) are the same, and their domains are also the same is correct.

What is domain?

List of values of x an equation can satisfy is called Domain.

What is range?

List of values y the function can generate is called range

For example, f(x)=x

it can satisfy real domain i.e. x∈R

and range is R

g(x) = 3 x + 6 - 8 and f(x) = 3x

Domain for both the function is R

Both the function can satisfy all the real numbers, so its range is also R.

Therefore,Option C The ranges of g(x) and f(x) are the same, and their domains are also the same is correct.

A. x = 180/60
B. x = 3

D. 13x + 33x + 14x = 90

Answers

A retail ice cream salesman divides his working days into 'sunny', 'medium', and 'cold'. He estimates that the probability of it being sunny is 0.2, and cold 0.3. If his gross sales on these three types of day are $50, $35, and $10 respectively on average and his average daily costs are $18 on any day.

Required:
a. Complete the probability distribution.
b. Find his expected profit per day.

Answers

Answer:

30.5

Step-by-step explanation:

Let ;

Sunny = S ; Medium = M ; Cold = C

_____ S _____ M ___ C

__X : 50 ____ 35 ___ 10

P(X) : 0.2 ____ 0.5 __ 0.3

P(M) = 1 - (0.2 + 0.3)

P(M) = 1 - 0.5 = 0.5

Expected profit per day, E(X)

E(X) = sum of (X * p(x)

E(X) = (50 * 0.2) + (35 * 0.5) + (10 * 0.3)

E(X) = 10 + 17.5 + 3

E(X) = 30.5

Plz help me and plz show your work.

Answers

Answer:

9.35

Step-by-step explanation:

This is a simple division problem all you have to do is 187 by 20 to get 9.35

Answer:

9.35

Step-by-step explanation:

In order to solve this, we need to use a method called long division. Long division is dividing but on a bigger scale. You would set up the problem like this:

187 ÷ 20

Now you see how many times 20 goes into 187.

Since it goes into 187 9 times, we know that our whole number is going to be 9. You would then need to figure out how many times 2 goes into 7. Because 2 goes into seven 3 1/2 times, we can now put our answer together. 9.35 is the answer.

You could also just use a calculator. Using a calculator would be much faster and simpliler.
