Tricia got a 56% on her math test.
If she answered 14 questions
correctly, how many were on the
test?

Answers

Answer 1

Answer:

25 Questions

Step-by-step explanation:

Rationing

This Question tests on the concept of Rationing using percentages.

Eg. 45% of 100 = 45, therefore 100% of 100 = 100.

Solution

Given information from the question:

56% = 14 Questions

1% = (14 ÷ 56) Questions

Total number of questions in the test = 100%

100% = (14 ÷ 56) × 100 Questions = 25

Answer 2

Answer:

[tex]\huge\boxed{\sf 25\ questions}[/tex]

Step-by-step explanation:

Let the total questions be x.

Given that,

56% of total questions = 14

Key: "of" means "to multiply", % means out of hundred.

[tex]\displaystyle \frac{56}{100} \times x = 14\\\\0.56 \times x = 14\\\\Divide\ 0.56\ to\ both\ sides\\\\x = 14/0.56\\\\x = 25[/tex]

So, there were 25 questions on the test.

Find the critical numbers of the function. (Enter your answers as a comma-separated list.)
f() = 6sec + 3tan , 0 < < 2

Answers

The critical numbers of the function are; θ = π/6, 5π/6

How to find the critical value of a trigonometric function?

We are given the trigonometric function as;

f(θ) =  6secθ + 3tanθ ; 0 < θ < 2π

The critical points of a function are defined as those points of the domain where the function is not differentiable or those points for which the derivative is equal to zero.

Let us find the first derivative;

f'(θ) = 6(-sin θ/cos² θ) + 3(1/cos² θ)

f'(θ) = (3 - 6sin θ)/cos² θ

At f'(θ) = 0, we have;

3 - 6sin θ = 0

θ = sin⁻¹(3/6)

Since sin is positive, then;

θ = π/6, 5π/6

Answers

A probability is a numerical representation of the likelihood or chance that a specific event will take place.

How to find the probabilities?

12% of peanut M&M’s = brown

15% = yellow

12% = red

23% = blue

23% = orange

15% = green

Here, Probability of an event is represented as P

a) P(not green) = 100% - 15%

                        = 85%

                        = 0.85

b) P(yellow or red) = 15% + 12%

                               = 27%

                               = 0.27

c) P(three blue) = 0.23*0.23 *0.23

                         = 0.012 (rounded to 3 decimal places)

d) P(not green if you choose 6 )= [tex](0.85)^{6}[/tex]

                                                    = 0. 377

e) P(at least 1 green if you choose 6 ) = 1 - 0.377

                                                              = 0.623

What is probability?Probability is the ability to happen. The subject of this area of mathematics is the occurrence of random events. From 0 to 1 is used to express the value. To forecast how likely occurrences are to occur, probability has been introduced in mathematics. The degree to which something is likely to happen is essentially the definition of probability. This is the fundamental theory of probability, which is also applied to the probability distribution, and from which you will discover the likelihood of results for a random experiment. We must first determine the total number of outcomes in order to calculate the probability that a single event will occur.

What is Division ?

One of the fundamental mathematical operations is division, which involves breaking a bigger number into smaller groups with the same number of components. How many groups will be created, for instance, if 30 students need to be separated into groups of five for a sporting event? The division operation may be used to quickly and simply fix such issues. In this case, we must divide 30 by 5. 30 x 5 = 6 will be the outcome. There will thus be 6 groups with 5 students each. The initial number, 30, which is obtained by multiplying 6 by 5 may be used to confirm this figure.

The names of the phrases connected with the division process are referred to as division parts. The division is made up of the following four components: dividend, divisor, quotient, and remainder.

Two friends can divide 76 blueberries by dividing 76 divided by 10 .

The value we get is Divisor is 10 , Dividend is 76

So, The Quotient is 7 and Remainder is 6

So there will be 7 box of 10 blueberries and 1 box with 6 berries.

Pictorial Representation is :

(10), (10), (10), (10), (10), (10), (10), (06).

Now since there are 7 bowls of 10 berries so 7 divide by 2 is 3 as quotient and 1 as remainder so 1 box will be split apart into 10 divided by 2 is 5 berries each.

Struggling on factoring quadratics. Could someone help me out with this worksheet, any examples of how to do the different types of problems would be great as well as finished problems

Answers

Answer:

When factoring, you want to get all of the terms on one side first and set all of it equal to 0. Many of the problems here are already in this format =0, but there are some where you'll have to move the terms around.

In these examples, it also looks like the highest power you have is x^2. This makes things easier to work with.

Let's just start with the first one, x^2 - 9x + 18 = 0.

We need to find two numbers that multiply to give us 18, and add together to give us -9. That would be -6 and -3.

-6 + -3 = -9

- 6 * -3 = 18

We can rewrite it now. This is the factored form.

(x - 6) * (x - 3) = 0

If you want to, you can go back to expanded form using the acronym 'FOIL'. First, Outside, Inside, Last. This refers to the order of multiplying the terms.

(x - 6) * (x - 3)

x * x = x^2

x * -3 = -3x

-6 * x = -6x

-6 * -3 = 18

Simplify

x^2 - 3x - 6x + 18 = 0

And we're back to where we started.

x^2 - 9x + 18 = 0

these final degrees.

Answers

Answer:

Bachelor's Degree: $55,000
Master's Degree: $61,000

Step-by-step explanation:

First start defining variables for each of the salaries

Let M be the salary of the master's individual

Let B be the salary of the bachelor's individual

Given:
Average yearly salary of an individual whose final degree is a master's is $49 thousand less than twice that of an individual whose final degree is a bachelor's

can be translated into the equation

M = 2B - 49,000

Subtract M from both sides and add 49,000 to both sides:

49,000 = 2B - M

Switch sides:

2B - M = 49,000   [1]

Together they earned 116,000 becomes

B + M = 116,000   [2]

Add equations [1] and [2] to eliminate M
2B - M + B + M = 49,000 +116000
3B = 165000

B = 165000/3 = 55,000

Using equation 2, B + M = 116000 we get

55000 + M = 116000

M = 116000 - 55000 = 61,000

Solution
Bachelor's Degree: $55,000
Master's Degree: $61,000

rectángulo de 17 cm de largo, como se
muestra en la figura. ¿Cuál es el área
de la franja amarilla en centímetros
cuadrados?

Answers

La franja amarilla del rectángulo tiene un área de 30 centímetros cuadrados.

¿Cuál es el área de la franja amarilla del rectángulo?

En este problema tenemos un rectángulo formado por dos cuadrados que se traslapan uno al otro. La franja amarilla es el área en la que los cuadrados se traslapan. La anchura del rectángulo es descrita por la siguiente ecuación:

(10 - x) + 2 · x = 17

Donde x se mide en centímetros.

A continuación, despejamos x en la ecuación descrita:

10 + x = 17

x = 7

Ahora, el área de la franja amarilla se determina mediante la fórmula de area de un rectángulo:

A = b · h

Donde:

b - Base del rectángulo, en centímetros. h - Altura del rectángulo, en centímetros. A - Área del rectángulo, en centímetros cuadrados.

A = (10 - 7) · 10

A = 3 · 10

A = 30

El área de la franja amarilla del rectángulo es igual a 30 centímetros cuadrados.

vitamin samples to give his
patients. The number of
samples remaining
decreases by 18% each
week. Which equation
represents the remaining
number of samples after x
weeks?

Answers

1000 - 180x represents the remaining number of samples after x weeks.

What is exponents?

Exponentiation could be a calculation, written as bⁿ, involving 2 numbers, the bottom b and also the exponent or power n, and pronounced as "b to the n".

Main body:

Consider what is actually happening in the question.

You begin with 1000 samples,  after it decreases to

=1000-18% of 1000

= 820

You can see the pattern shows that the number of samples decreases 18% every week ,1000-18% of 1000 - 18% 0f 1000.

= 1000 - 180x where x denotes number of weeks.

Hence 1000 - 180x represents the remaining number of samples after x weeks.

FIND THE TWO POINTS HAVING AN X-COORDNATE OF 3 WHOSE DISTANCE FROM THE POINT(-2,-1) IS 13.
POINT 1: (3, ?)
POINT 2: (3, ?)

Answers

To find the two points having an x-coordinate of 3 whose distance from the point (-2, -1) is 13, you can use the distance formula:

Distance = √((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) is the coordinates of the first point, and (x2, y2) is the coordinates of the second point.

In this case, you can use the distance formula to find the y-coordinates of the two points having an x-coordinate of 3:

Distance = √((3 - (-2))^2 + (y - (-1))^2)

= √(5^2 + (y + 1)^2)

= √(25 + y^2 + 2y + 1)

= √(26 + y^2 + 2y)

= 13

If you set the distance equal to 13 and simplify the equation, you get:

y^2 + 2y + 12 = 0

This is a quadratic equation, which means it can be solved using the quadratic formula:

y = (-b ± √(b^2 - 4ac)) / (2a)

where a, b, and c are the coefficients of the quadratic equation.

Substituting the values into the quadratic formula, you get:

y = (-2 ± √(-2^2 - 4 * 1 * 12)) / (2 * 1)

= (-2 ± √(-4 - 48)) / 2

= (-2 ± √(-52)) / 2

Since the square root of a negative number is not a real number.

The correct option C: -4 ≤ x ≤ -2, are the intervals in which the graph is constant.

Explain the term constant function?An algebraic expression known as a linear expression has terms that are either constants or variables raised to first power. Alternatively put, no of the exponents could be greater than 1.A linear function with a slope of 0 is known as a constant function. The function's value will remain constant regardless of the value you select for "x." A constant function has a graph that is a horizontal line and through y-intercept, "b." Example A's graph is indeed a horizontal line that passes through y = 4 since b is equal to 4.

So, from the shown graph, the horizontal line have the constant function which lies in the intervals -4 ≤ x ≤ -2.

Thus, in the intervals -4 ≤ x ≤ -2, the function is constant.
