Answer:

D. 0.80

Step-by-step explanation:

P(A or B) = P(A) + P(B)

P(A or B) = 0.60 + 0.20

P(A or B) = 0.80

The probability of P(A or B ) is 0.80.

The correct option is D.

Since A and B are mutually exclusive events, they cannot occur simultaneously.

Thus, the probability of A or B occurring is equal to the sum of their individual probabilities:

P(A or B) = P(A) + P(B)

Therefore, we need to subtract the probability of the intersection of A and B:

P(A and B) = 0 (since A and B are mutually exclusive)

Thus, we have:

P(A or B) = P(A) + P(B) - P(A and B)

Substitute all the given values to the equation,

we get,

= 0.60 + 0.20 - 0

= 0.80

Therefore, the probability of A or B occurring is 0.80 or 80%.

D. 5 for x less than or equal to 4, equals 2x for x between 4 and 6 including 6, and equals 4 for x greater than 6 Domain: All real numbers.

Step-by-step explanation:

Find the complete diagram attached

First we need to get the derivative of the functions

For the function f(x) = 5x - 6

Using the formula

If f(x) = axⁿ

f'(x) = naxⁿ⁻¹

For the function f(x) = 5x - 6

f'(x) = 1(5)x¹⁻¹

f'(x) = 5x⁰

f'(x) = 5

For the function f(x) =x²-2

f'(x) = 2x²⁻¹

f'(x) = 2x

For the function f(x) = 4x+10

f'(x) = 1(4)x¹⁻¹

f'(x) = 4x⁰

f'(x) = 4

Get the domain

The domain is the value of the input variable x for which the functions exists. For the functions given, the domain will be on all real numbers i.e the functions will exists for any value of x on the number line.

Answer:

y = -3x + 7

Step-by-step explanation:

Again, pick a random point. I chose point (0,7). Then, we see how many units it takes to reach the next point. Let's try it. First, we move down 3 units, rise = -3, then move right 1 unit, run 1. So slope is rise over run, so -3/1 = -3. Then, for the y intercept, just see the y value when x = 0.

Answer:

y = - 3x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 7) and (x₂, y₂ ) = (2, 1) ← 2 points on the line

m = [tex]\frac{1-7}{2-0}[/tex] = [tex]\frac{-6}{2}[/tex] = - 3

The line crosses the y- axis at (0, 7 ) ⇒ c = 7

y = - 3x + 7 ← equation of line

The distance of the boat from the base of the cliff is 114 feet.

There are three commonly used trigonometric identities.

Sin x = 1/ cosec x

Cos x = 1/ sec x

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x

We have,

The distance of the boat from the base of the cliff is 114 feet.

Answer:

The answer is C: (-9,1) and (5,1). took the test. Good luck!

Step-by-step explanation:

The coordinates of the vertices that lie on the major axis of the conic section can be written as (5,1) and (-9,1), so option C is correct.

A formula known as an equation uses the equals sign to denote the equality of two expressions.

Given equation:

(x + 2)² / 49 + (y - 1)² / 25 = 1

The above equation can be simplified as,

(x + 2)² / 7² + (y - 1)² / 5² = 1

The left side has to be equal to 1, the (x + 2)² / 7² the term has to be equivalent to 1, and the term (y - 1)² / 5² to be equivalent to zero

(y - 1)² / 5² = 0, y - 1 = 0, y = 1

(x + 2)² / 7² = 1

(x + 2)² = 49

(x + 2) = ±7

x = +7 - 2 = 5

x = -7 - 2 = -9

Therefore, the coordinates of the vertices that lie on the major axis of the conic section can be written as (5,1) and (-9,1).

Answer:

A

Step-by-step explanation:

We can see there are 2 parts of this function: one line for x<1 (because there is a circle for x=1, meaning it disincludes it) and one line for x >= 1 (because there is a filled circle for x=1, meaning it includes it). Therefore, we can disregard choice B (because it has x <= 1 and x > 1 instead of x<1 and x>= 1).

Notice that the part that x<1 passes through the origin, meaning the y-intercept is 0. In y= mx + b form of a line, b is the y-intercept, so b = 0 and we are looking for something in the form of y = mx for x < 1. Wee see that only in choice A that this is satisfied. Therefore, the answer is A.
