There are 35 red marbles, 8 blue marbles, and 7 green marbles in a bag. What is the theoretical probability of randomly drawing a red marble?

○ 35%
○ 25%
○ 42.9%
○ 70%

Answers

Answer 1

Answer:

70%

Step-by-step explanation: 35/50 equals 0.7

Answer 2

Answer:

70%

Step-by-step explanation:

The total number of marbles will be 35 + 8 + 7 = 50 marbles in total (all the colors added together). The probability of drawing a red marble will be the number of red marbles divided by the total marbles. This also fits the  probability formula of (desired outcomes)/(total number of outcomes. Thus, we have 35 red marbles and 50 marbles in total. So, we get 35/50, which is 70%.

In 2017 the population of Rexburg, Idaho was 28,337 people. The population was expected to grow at a rate of about 1.26% per year. Based on these numbers, what would we predict the population of Rexburg will be in the year 2022?

(Round to the nearest whole number.)

Answers

Answer:

30,122

Step-by-step explanation:

This probably isn't the fastest way to solve but....

28,337x1.26%= 357

357x5=1785

28,337+1785=30,122

The 5 came from the # of years the population is increasing

We are required to find the population of Rexburg will be in the year 2022

The population of Rexburg will be in the year 2022 is 30,122 people

Given:

2017 population = 28,337 people

Growth rate per year = 1.26%

let

n = number of years between current and predicted

= 2022 - 2017

n = 5 years

Yearly growth rate = 28,337 × 1.26%

= 28,337 × 0.0126

= 357.0462

Predicted population in 2022 = 2017 population + (357.0462 ×5)

= 28,337 + 1,785.231

= 30,122.231

Approximately, 30,122 people in 2022.

Therefore, the population of Rexburg will be in the year 2022 is 30,122 people

Answers

Answer:

y=-32, 0, -16, -4, 16

Step-by-step explanation:

y=4(-6)-8= -32

y=4(2)-8 = 0

y=4(-2)-8 = -16

y=4(1) -8 = -4

y=4(6) -8= 16

For the given equation of the line, the complete table is attached below.

Use the concept of the equation of line defined as:

A line has length but no width, making it a one-dimensional figure. A line is made up of a collection of points that can be stretched indefinitely in opposing directions. Two points in a two-dimensional plane determine it.

The given equation of a line is,

y = 4x - x

To complete the table:

Put x = -6 in this equation,

y =  (-4)(-6) - 8

y = 16

Put x = 2 in the equation,

y =  (-4)(2) - 8

y = -16

Put x = -2 in the equation,

y =  (-4)(-2) - 8

y = 0

Put x = 1 in the equation,

y =  (-4)(1) - 8

y = -12

Put x = 6 in the equation,

y =  (-4)(6) - 8

y = -32

The complete table is attached below.

x-intercept: [tex](-2,0)[/tex]

Step-by-step explanation:

Hi there!

Important things to note:

the y-intercept occurs when x=0the x-intercept occurs when y=0

1) Find the y-intercept

[tex]-5x-4y=10[/tex]

Substitute x with 0

[tex]-5(0)-4y=10\\0-4y=10\\-4y=10[/tex]

Divide both sides by -4

[tex]\frac{-4y}{-4} =\frac{10}{-4} \\y=-\frac{5}{2}[/tex]

Therefore, the y-intercept is [tex]-\frac{5}{2}[/tex]. When written in (x,y) form, x will always be 0 while y is the y-intercept:

[tex](0,-\frac{5}{2} )[/tex]

2) Find the x-intercept

[tex]-5x-4y=10[/tex]

Substitute y with 0

[tex]-5x-4(0)=10\\-5x-0=10\\-5x=10[/tex]

Divide both sides by -5

[tex]-5x=10\\\frac{-5x}{-5}= \frac{10}{-5} \\x=-2[/tex]

Therefore, the x-intercept is -2. When written in (x,y) form, x will always be the x-intercept while y is always 0:

From the equation, find the axis of symmetry of the parabola. y = 3 x squared minus 12 x + 11 a. x = negative 2 c. x = 1 b. x = 2 d. x = negative 1 Please select the best answer from the choices provided A B C D

Answers

Answer:

the axis of symmetry would be: b. x=2

The equation of the axis of symmetry of the parabola will be x = 2. Then the correct option is B.

What is the equation of the parabola?

Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.

Then the equation of the parabola will be given as,

y = a(x - h)² + k

The equation is given below.

y = 3x² - 12x + 11

Convert the equation into a vertex form. Then we have

y = 3x² - 12x + 11

y = 3x² - 12x + 12 - 1

y = 3(x² - 4x + 4) - 1

y = 3(x - 2)² - 1

The equation of the axis of symmetry of the parabola is given as,

x - 2 = 0

x = 2

The equation of the axis of symmetry of the parabola will be x = 2. Then the correct option is B.

Kyle is buying a $220 bicycle if the bicycle is on sale for 35% off how much will he save

Answers

Answer:

$77

Step-by-step explanation:

Okay so first, we know that the bicycle is 220 dollars. So we got to  multiply that to the percent. We can't muiltiply it into the percent yet so we turn that percent into 0.35

220 * 0.35

This equals to 77. That's the answer but it's not that simple, cause we aren't finished!

So we know that 35 percent of 220 is 77 dollars. So subtract that to 220!

220 - 77

This is equal to 143. Now how much will he save? He will save 220 - 143, which is 77! That's how we know the answer! I'm sure this is correct, if itsn't please comment! Have a great day!

Answer:

$143

Step-by-step explanation you wanna see how much 35% is out of 220

35% = 0.35

220 * 0.35 = 77 = discount

Now you want to see how much it will be when the discount is applied

220-77 = 143

The bicycle is $143 when discount is applied, you save $77

Answers

Answer: None of them. It should be 150 degrees.

See the explanation below for more details

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

Explanation:

To convert from radians to degrees, we multiply by the factor (180/pi)

The formula we can use is

y = (180/pi)*x

where x is the angle in radians, and y is the angle in degrees

Plug in x = (5/6)pi and evaluate

y = (180/pi)*x

y = (180/pi)*(5/6)*pi

y = (180/pi)*(5pi/6)

y = (180*5pi)/(pi*6)

y = (180*5)/(6)

y = (6*30*5)/(6)

y = (30*5)/(1)

y = 150

So the angle (5/6)pi radians, aka 5pi/6 radians, is equivalent to 150 degrees. Unfortunately this answer choice isn't listed. You'll have to let your teacher know there's a typo somewhere.
