A spinner is spun that has 15 equal-sized sections numbered 1 to 15. What is the probability the spinner lands on a multiple of five?

Answers

Answer 1

Answer:

1/5

Step-by-step explanation:

P(event) = # of favorable outcomes / # of total outcomes. Multiples of 5 are 5, 10, 15, 20, 25, 30, 35, 40 ... and there are 3 multiples of 5 within 1 to 15. So the # of favorable outcomes is 3. # of total outcomes is 15 because there are 15 equal-sized sections.

P = 3/15 = 1/5

Given the following information, determine which lines, if any, are parallel. State the
postulate or theorem that justifies your answer.

Answers

Answer:

parallel lines a and b

parallel lines l and m

Step-by-step explanation:

25 A.

Angles 3 and 7 are alternate interior angles of lines a and b cut by transversal l.

Since angles 3 and 7 are congruent, lines a and b are parallel by the theorem:

If two lines are cut by a transversal such that alternate interior angles are congruent, then the lines are parallel.

25 B.

Angles 5 and 12 are same side interior angles of lines l and m and transversal b.

Since the sum of the measures of the angles 5 and 12 is 180, then angles 5 and 12 are supplementary angles making lines l and m parallel by the theorem:

If two lines are cut by a transversal such that same side interior angles are supplementary, then the lines are parallel.

You are only asked to draw the figure. You are not asked about anything to do with the standard form. So the drawing you need is below what is written here.

You should notice that the graph is in the shape of a cup that contain a liquid. It has a low point at (2,2) and a y intercept at 6. The y intercept occurs when x = 0.

The low point is reached when (x - 2) = 0. That makes x = 2. If x is anything but 2 something will be added on to the graph and f(x) will larger than 2.

Answers

Answer: Choice B)  right 3, up 4

=============================================================

Explanation:

When going from f(x) to f(x-3), we replaced x with x-3.

Doing this shifts the xy axis 3 units to the left since each x input is three units smaller than before. If we had the f(x) curve fixed in place while the axis moves like this, then it gives the illusion of the curve moving 3 units to the right.

The +4 at the end adds 4 to each y coordinate to shift things 4 units up.

Answers

Answer:

find the value of x if 7,x and 11 are in A.p.​

Answers

Answer:

x = 9

Step-by-step explanation:

since the terms are in AP then there is a common difference between consecutive terms, that is

a₂ - a₁ = a₃ - a₂ ( substitute values )

x - 7 = 11 - x ( add x to both sides )

2x - 7 = 11 ( add 7 to both sides )

2x = 18 ( divide both sides by 2 )

x = 9

Answer:

9

Step-by-step explanation:

The nth term of an AP has the formular

a+ ( n - 1 ) d

a = first term

n = number of terms

d = common difference

common difference d = T2 - T1 0r T3 - T2

d = x - 7 or 11 - x

Therefore,

3rd term

a + (3 - 1)d

a + 2d

Hence,

7 +2d = 11

substitute the value of d above

7 + 2 (x -7) = 11

7 + 2x - 14 = 11

2x = 11 +14 -7

2x = 18

dividing bothsides by 2

x = 18/2

For the graph of a linear function the slope of the line is positive, option A is correct.

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Let the line is passing through points (-4, -1) and (0, 0)

m=1/4

The slope value is positive

Hence, for the graph of a linear function the slope of the line is positive, option A is correct.

A white tailed deer can sprint at speeds up to 30 miles per hour. American bison can run at speeds up to 3,520 feet per minute. Which animal is faster and by how many miles per hour ? There are 5,289 feet in one mile

Answers

We will see that the bison is faster, by 9.9 miles per hour.

Which animal is faster?

We know that the deer's speed is:

D = 30 mi/h

The bison's speed is:

B = 3,520 ft/min.

We want to convert the second speed to miles per hour, then we can use:

1 hour = 60 min

1 mile = 5289 ft

So, to get the speed in miles per hour, we need to multiply by 60 and divide by 5289, we will get:

B = 3,520 ft/min = 3,520*(60/5289) mi/h = 39.9 mi/h

So we can see that the bison is faster, by 9.9 miles per hour.

where (h, k ) are the coordinates of the vertex and a is a multiplier

here (h, k ) = (0, 1 ) , then

y = a(x - 0)² + 1 = ax² + 1

to find a substitute any other point that lies on the graph into the equation

The playing time X of classical CDs has the normal distribution with mean 54 and standard
deviation 5; the N(54, 5) distribution. What is the relative frequency of classical CDs with playing
time X between 49 and 69 minutes?

Answers

Using the normal distribution, it is found that the relative frequency of classical CDs with playing time X between 49 and 69 minutes is 0.8403 = 84.03%.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The mean and the standard deviation are given, respectively, by:

[tex]\mu = 54, \sigma = 5[/tex]

The relative frequency of classical CDs with playing time X between 49 and 69 minutes is the p-value of Z when X = 69 subtracted by the p-value of Z when X = 49, hence:

X = 69:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{69 - 54}{5}[/tex]

Z = 3

Z = 3 has a p-value of 0.9987.

X = 49:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{49 - 54}{5}[/tex]

Z = -1

Z = -1 has a p-value of 0.1584.

0.9987 - 0.1584 = 0.8403.
