Answer 1

Answer:

there is no real solution for M

Step-by-step explanation:

Answer 2

Answer:

M = ± 11i or no real solution

Step-by-step explanation:

First square root the equation using the even roots property:

M = ±√(-1)(121)

take out the square root of -1, which is i:

M = ± i √(121)

then the square root of 121, which is 11:

M = ± 11i

NOTE: If you asked for a real solution, the answer is:

no real solution because there is a negative under the square root, which cannot be square rooted without i.

Write the equation of the following line in slope-intercept form.

Answers

Answer:

y = [tex]\frac{2}{5}[/tex] x + 4

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 ) = (- 5, 2) and (x₂, y₂ ) = (0, 4) ← 2 points on the line

m = [tex]\frac{4-2}{0-(-5)}[/tex] = [tex]\frac{2}{0+5}[/tex] = [tex]\frac{2}{5}[/tex]

The line crosses the y- axis at (0, 4 ) ⇒ c = 4

y = [tex]\frac{2}{5}[/tex] x + 4 ← equation of line

M is the midpoint of PQ. PM = 5x+8. PQ = 76. Find the value of x.

Answers

Answer:

x = 6

Step-by-step explanation:

Since M is the midpoint of PQ

PM = MQ = 1/2 PQ

5x+8 = 1/2(76)

5x+8 = 38

5x = 38-8=30

x = 30/5 = 6

Answer:

x = 6

Step-by-step explanation:

First, let's revise a few definitions.

Definition of midpoint: The point that is in the middle of a line.

We know that:

M is the midpoint of PQPM = 5x + 8PQ = 762PM = PQ

Work:

2PM = PQ=> 2(5x + 8) = 76=> 10x + 16 = 76=> 10x = 76 - 16=> 10x = 60=> x = 6

Hence, the value of x is 6 units.

Answers

The probability of a sporting event being cancelled due to rain or lightning is 6/25

What is Probability?

This is the likelihood or chance that an event will occur.

Probability = Expected/Total

Given the following

Pr(rain) = 3/5Pr (lightening) = 2/5

The probability of a sporting event being canceled due to rain or lightning = 3/5 * 2/5

The probability of a sporting event being canceled due to rain or lightning = 6/25

Hence the probability of a sporting event being cancelled due to rain or lightning is 6/25
