After 100 spins, Lincoln calculated the probability that he would spin a prime number to be 0.35. Using the
spinner, what is the theoretical probability of spinning a prime number?
An 15

Answers

Answer 1

Given:

Total number of spins = 100

Probability that he would spin a prime number to be 0.35.

To find:

The theoretical probability of spinning a prime number.

Solution:

Total numbers from 1 to 100 = 100

Total prime numbers from 1 to 100 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

So, the prime numbers from 1 to 100 = 25

Now, the probability of spinning a prime number is

[tex]\text{probability}=\dfrac{\text{Total prime numbers from 1 to 100}}{\text{Total numbers from 1 to 100}}[/tex]

[tex]\text{probability}=\dfrac{25}{100}[/tex]

[tex]\text{probability}=0.25[/tex]

Therefore, the theoretical probability of spinning a prime number is 0.25.

If there are 2.54 centimeters in an inch and 12 inches in a foot, how many centimeters in 3 feet

Answers

Answer:

91.44

Step-by-step explanation:

Answer:

3 ft = 91.44 cm

Step-by-step explanation:

We want to convert 3 ft to cm.

So we need a conversion factor.

Multiplying 3 ft by (12 in / 1 ft results in 36 in (this is equivalent to 3 ft).

Next, we convert 36 in to cm:

36 in    2.54 cm

-------- * ------------- = 91.44 cm

please be fast ill give brainliest How many solutions does the system have? y=1/2x-1 and y=-x+5

Answers

Answer:

(4, 1)

Step-by-step explanation:

since y=1/2x-1 in the first equation, you can substitute it into the second one:

1/2x - 1 = -x + 5

then add x to both sides:

3/2x - 1 = 5

then add 1 to both sides:

3/2x = 6

then divide both sides by the fraction to get:

x=4

then you substitute 4 into y=1/2x - 1

y = 1/2(4)-1

y = 1

so your answer is x=4 and y=1

Prove the following statement: If the x- and y-intercepts of a line are identical nonzero numbers, the line must have a slope of -1.
What is the x-intercept you are using?
What is the y-intercept you are using?
Show what you did to prove the slope is -1

Answers

Answer:

Step-by-step explanation:

Proof:

If:

x intercept is at a number nonzero "a"

so the point where it intersects the x-axis is at (a,0)

y-intercept is at the same nonzeronumber "a"

so the point where it intersects the y-axis is at (0,a)

Then:

slope between point (a,0) and (0,a) is m= (y2-y1)/(x2-x1) = 0-a/a-0=-a/a= -1

x intercept is 2 (for example)

so the point where it intersects the x-axis is at (2,0)

y-intercept is 2

so the point where it intersects the y-axis is at (0,2)

slope between point (2,0) and (0,2) is m= (y2-y1)/(x2-x1) = 0-2/2-0=-2/2=-1

A. Y=25/4x
B. Y=116/5x
C. Y=4/25x
D. Y=64x

Answers

Answer:

C. Y=4/25x

Step-by-step explanation:

If y varies directly as x, tis is expressed as;

y ∝ x

y = kx

k is the constant of proportionality

Goven

y = 16/5 and x = 20

16/5 = 20k

16 = 100k

k = 16/100

k = 4/25

Substitute k = 4/25 into the original equation

y = kx

y = 4/25 x

Hence the required expression is y = 4/25 x

Answers

Answer:

This function doesn't make sense, unless you make it f(t)=225(1.23)^x. I will assume that you forgot to add the x squared. The rate of decay is 23%. Since the base is between 1 and 0, it is an exponential decay and you'll need to subtract the r-value with 1. (If it were an exponential growth, you would have to add 1.) The initial value or the a-value is 225.

log16^*+log4^*+log2^*=7​

Answers

Answer:

[tex]x = 16[/tex]

Step-by-step explanation:

Given

[tex]log_{16}(x) + log_4(x) + log_2(x) = 7[/tex]

Required

Solve for x

[tex]log_{16}(x) + log_4(x) + log_2(x) = 7[/tex]

Change base of 16 and base of 4 to base 2

[tex]\frac{log_2(x)}{log_2(16)} + \frac{log_2(x)}{log_2(4)} + log_2(x) = 7[/tex]

Express 16 and 4 as 2^4 and 2^2 respectively

[tex]\frac{log_2(x)}{log_2(2^4)} + \frac{log_2(x)}{log_2(2^2)} + log_2(x) = 7[/tex]

The above can be rewritten as:

[tex]\frac{log_2(x)}{4log_22} + \frac{log_2(x)}{2log_22} + log_2(x) = 7[/tex]

[tex]log_22 = 1[/tex]

So, we have:

[tex]\frac{log_2(x)}{4*1} + \frac{log_2(x)}{2*1} + log_2(x) = 7[/tex]

[tex]\frac{1}{4}log_2(x) + \frac{1}{2}log_2(x) + log_2(x) = 7[/tex]

Multiply through by 4

[tex]4(\frac{1}{4}log_2(x) + \frac{1}{2}log_2(x) + log_2(x)) = 7 * 4[/tex]

[tex]log_2(x) + 2}log_2(x) + 4log_2(x) = 28[/tex]

[tex]7log_2(x) = 28[/tex]

Divide through by 7

[tex]\frac{7log_2(x)}{7} = \frac{28}{7}[/tex]

[tex]log_2(x) = 4[/tex]

Apply the following law of logarithm:

If [tex]log_ab = c[/tex] Then [tex]b = a^c[/tex]

So, we have:

[tex]x = 2^4[/tex]

[tex]x = 16[/tex]

Dennis has less than 70 min. to spend on some homework questions. He spent 10 min. on the first two questions. The rest of the questions will take 52 min. each.

Which statement describes the solution to this inequality?

Drag and drop the answer into the box.

Answers

Answer:

A. Dennis can complete less than 24 questions.

Step-by-step explanation:

Let x represent the remaining number of questions to be completed.  He can complete each of them in 5/2 minutes each; this gives us the expression 5/2x.

He has already spent 10 minutes; this gives us 5/2x+10.

He has less than 70 minutes to spend; this gives us the inequality

5/2x+10<70

Subtract 10 from each side:

5/2x+10-10 < 70-10

5/2x < 60

Divide both sides by 5/2:

5/2x÷5/2 < 60÷5/2

x < 60/1 ÷ 5/2

To divide fractions, flip the second one and multiply:

x < 60/1 × 2/5

x < 120/5

x < 24

Answer:

Dennis can complete fewer than 24 questions.

Some resources are stored in different forms, which can be processed to obtain useful products, such as petroleum, minerals, or metals. In terms of energy resources, there are two types of natural resources that are used to generate energy: renewable resources, such as water, sunlight, and wind; and nonrenewable resources, such as such as coal, natural gas, or crude oil. The nonrenewable energy sources are widely used around the world. When fossil fuels are burned for energy, carbon dioxide (CO2) is released into the environment. Carbon dioxide is one of the greenhouse gases in the atmosphere that helps to keep the planet warm, as it traps the radiation coming from the Sun. Too much carbon dioxide in the atmosphere can retain high amounts of thermal energy and cause the temperature to rise, which can have devastating effects on the environment. In the last century, the level of atmospheric carbon has increased at an alarming rate.The graph shows the increase in the concentration of carbon dioxide in the atmosphere since 1900.QUESTION: Before the eighteenth century, coal was used by humans in many places on Earth for cooking and heating.
