Answer:

189 and 202

Step-by-step explanation:

An outlier is a value that will have an effect on the mean of a set of values. It has an obvious difference compared to other values. They can be easily determined in a set of given data by mere observation.

From the given data in the question, it would be observed that the chronological difference among set of the data is either 1, 2, 3 or 4. But the two numbers that could be referred to as outliers are 189 and 202. This is because the have a wider range than others.

Step-by-step explanation:

The bar graph is not completely labeled, but in the context of the question it seems safe to assume that the vertical scale can be considered to represent relative frequency.

So, the shortest bar is the one with the lowest frequency. The horizontal scale identifies that as 101-120. If we assume that is salary in thousands of dollars, then Choice D is appropriate.

Answer:

Factor x3 – 7x2 – 5x + 35 by grouping. What is the resulting expression?

Step-by-step explanation:

Edge 2021

Polynomial is an expression that consists of indeterminates(variable) and coefficients. The correct option is A.

Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.

For the given expression x³ – 7x² – 5x + 35 the factorisation by grouping can be done as,

x³ – 7x² – 5x + 35

Take x² as common from the first two terms, while -5 as common from the last two terms,

= x²(x – 7) –5(x  – 7)

Take (x–7) as the common term from the two terms,

= (x² – 5)(x – 7)

Hence, the correct option is A.

Answer:

144 feet

5 seconds

Step-by-step explanation:

a.

we want the maximum (or the vertex)

-64/-32= 2

-16*2²+64*2+80=144

b.

Here we want the point in which the y=0

In other words, we want the x-intercept

-16x²+64x+80= -16(x-5)(x+1)

so we have

(5,0) and (-1,0)

A) the maximum height of the apple is 144 feet. B) it will take 1 second for the apple to reach the ground.

How to determine How many seconds will it take for the apple to reach the ground

a. To find the maximum height of the apple, we need to determine the vertex of the parabolic equation. The vertex represents the maximum point of the parabola.

The equation for the height of the apple is given as h = -16t^2 + 64t + 80.

To find the t-value at the vertex, we can use the formula t = -b / (2a), where a, b, and c are the coefficients in the equation.

In this case, a = -16 and b = 64. Substituting these values into the formula:

t = -64 / (2 * -16)

t = -64 / -32

t = 2

So, the apple reaches its maximum height at t = 2 seconds.

To find the maximum height (h), we substitute the value of t = 2 into the equation:

h = -16(2)^2 + 64(2) + 80

h = -64 + 128 + 80

h = 144

Therefore, the maximum height of the apple is 144 feet.

b. To find the time it takes for the apple to reach the ground, we set h = 0 in the equation and solve for t:

0 = -16t^2 + 64t + 80

We can factor this equation or use the quadratic formula. Let's use the quadratic formula:

t = (-b ± √(b^2 - 4ac)) / (2a)

In this case, a = -16, b = 64, and c = 80. Substituting these values:

t = (-64 ± √(64^2 - 4(-16)(80))) / (2(-16))

t = (-64 ± √(4096 + 5120)) / (-32)

t = (-64 ± √9216) / (-32)

t = (-64 ± 96) / (-32)

We have two possible solutions:

t1 = (-64 + 96) / (-32) = 1

t2 = (-64 - 96) / (-32) = 5

Since the apple was launched upward, we consider the positive solution t1 = 1.

Therefore, it will take 1 second for the apple to reach the ground.

Answer:

Step-by-step explanation:

By the Isosceles Triangle Theorem, angle O and angle M are congruent because the sides across from each of these angles are congruent. therefore, O = M = 4y - 15. Since, by the Triangle Angle-Sum Theorem all the angles of a triangle have to add up to equal 180 AND angle O and angle M are the same:

7y + 4y - 15 + 4y - 15 = 180 and

15y - 30 = 180 and

15y = 210 so

y = 14. Plug 14 in for y in 7y and get that

∠N = 98°

Answer:

(1,2)

Step-by-step explanation:

y = 2x. y = -x+3

Set the two equations equal

2x = -x+3

Add x to each side

2x+x = -x+x+3

3x = 3

Divide by 3

3x/3 = 3/3

x = 1

Now find y

y =2x = 2(1) = 2

(1,2)

Solve like how you solve the system of equations. System of Equations are to find the intercept of both graphs or to find which coordinate points are solution to both equations.

We are given the equations below:

[tex] \large{ \begin{cases} y = 2x \\ y = - x + 3 \end{cases}}[/tex]

Since both equations are y-isolated and we want to find the coordinate point that both equations have or the coordinate point that is a part of two equations.

[tex] \large{2 x = - x + 3}[/tex]

Isolate the x-term by adding both sides by x.

[tex] \large{2x + x = - x + 3 + x} \\ \large{3x = 3}[/tex]

Divide both sides by 3 so we can finally get the x-isolated equation.

[tex] \large{ \frac{3x}{3} = \frac{3}{3} \longrightarrow x = 1 }[/tex]

Next step is to find the value of y. x-term and y-term both have relations. That means when substituting x-term, we get y-term. Therefore, substitute x = 1 in any given equations. It is not necessary to substitute both, only one is fine. I will choose the first equation to solve for y-value.

[tex] \large{y = 2x}[/tex]

Substitute x = 1:

[tex] \large{y = 2(1) \longrightarrow y = 2}[/tex]

The value of y is 2 when x is 1. Since we want the answer to be in coordinate form or ordered pair. From (x,y) - we get (1,2).

Answer:

X=60°

Y=50°

Step-by-step explanation:

Triangles must equal 180° when you add all angles together.

Triangle with angle X

To find the value of Y takes a few more steps, but it isn't hard!

Angle Y is on a line, which equals 180° just like a triangle.

We know X=60°, but we don't know what the blank angle equals.

We use the same steps as we did when finding X

We know that the blank angle=70° and that X=60°

Since the line equals 180, we add the two angles and then subtract from 180, just like before!
