Answer:

D. $125,000

Step-by-step explanation:

1500 square feet multiplied by $83.33 per square foot = $124,995

which is about 125,000.

We will see that the theoretical probability that the name Josh is chosen is P = 1/7.

7 names are put on a hat, theoretically, we assume that all the names have the same probability of being randomly drawn from the hat. So it does not depend on the given information, that would give us the experimental probability.

Then, for the theoretical probability we will have the quotient between the number of names in the hat that are Josh (there is only one) and the total number of names in the hat, this gives:

P(Josh) = 1/7

Answer:

the second one

Step-by-step explanation:

The y-intercept is -4 so we can eliminate the third and fourth options. Substitute (0,0) into the equation and from that we can say that it is not true (0 is not less than -4). Because it isn't true, we shade in the side that doesn't have the origin in it.

Answer:

  58.9 ft²

Step-by-step explanation:

The horse is constrained to 3/4 of a circle that has a 5 ft radius. Then the area is ...

  A = (3/4)πr²

  A = (3/4)π(5 ft)² = 75π/4 ft²

  A ≈ 58.9 ft²

The horse has a maximum grazing area of 58.9 ft².

_____

In the real world, a 5 ft rope is awfully short. The grazing area would depend on how high on the barn it is tied, and where on the horse it is tied.

The probability of at least two coins landing on heads is given by the equation P = 11/16

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

The value of probability lies between 0 and 1

Given data ,

Let the probability of at least two coins landing on heads be P

Now , the equation will be

Let the coin landing on its head be represented as = H

Let the coin landing on its tail be represented as = T

The possible outcomes of flipping a coin be represented by set A

Set A = {  HHHH , HHHT , HHTH , HHTT , HTHH , HTHT , HTTH , HTTT , THHH , THHT , THTH , THTT , TTHH , TTHT , TTTH , TTTT }

So ,

The total number of outcomes = 16 outcomes

The number of outcomes where at least 2 coins land on their heads is given by set B

Set B = { HHHH , HHHT , HHTH , HHTT , HTHH , HTHT , HTTH , THHH , THHT , THTH , TTHH }

The number of outcomes of set B = 11

So , the probability of at least two coins landing on heads be P = number of outcomes of set B / total number of outcomes

Substituting the values in the equation , we get

Probability of at least two coins landing on heads be P = 11/16

Therefore , the value of P is 11/16

Hence , the probability is 11/16

Answer: 2cm

Step-by-step explanation:

From the question, we are informed that a microscope dilates the image of an organism 4 times its original dimensions and that the radius of a circular organism has seen by a microscope is 8 cm.

Since the microscope makes the objects 4 times bigger, then the original radius will be:

= 8cm/4

= 2cm

The radius of the actual organism is 2cm.

Answer:C 5000 feet

Step-by-step explanation:It’s slightly less then a mile.

Answer:

Step-by-step explanation:

First of all, you would want to convert all of the distances into the same units.

Let's convert the distances to miles.

5,000 inches = about 0.08 miles

0.5 miles = 0.5 miles

5,000 feet = about 0.9 miles

500 yards = about 0.3 miles

Now, we compare the values.

We can easily place 5,000 inches last, because when converted to miles it's 0.08.

0.08<0.3<0.5<0.9

5,000 inches<500 yards<0.5 miles<5,000 feet

Hence, the answer is C.

Answer:

Answer is B

Step-by-step explanation:

The hypotenuse of a triangle is always twice the length of the shorter side in a 30 60 90 triangle. So if the hypotenuse is 4 the shortest side must be 2. Meaning the sum will be 6. The medium side is the shortest side times the square root of 3. So we have 2[tex]\sqrt{3}[/tex]. Our final equation is 6+ 2[tex]\sqrt{3}[/tex].

Answer:

f(x) = (1/2)*x + 6

Step-by-step explanation:

We have the following equation:

y - 8 = (1/2)*(x - 4)

Applying distributive property:

y - 8 = (1/2)*x - (1/2)*4

y - 8 = (1/2)*x - 2

Isolating y:

y = (1/2)*x - 2 + 8

y = (1/2)*x + 6

When we talk about functions, y and f(x) refers to the same. So, we can rewrite the last equations as:

f(x) = (1/2)*x + 6

Answer:

2*(4+6)

Step-by-step explanation:

2 multiplied by the sum of 4 and 6 is 2 times 10, which equal 20. Hope this helps :)

Answer:

2x(4+6)

The factors of 20 are 1,20||| 2,10 |||4,5||||

We need to somehow get both of those numbers

We have 4 but there is no way to get 5 so only 1,20 and 2,10 are left

We have 2 and we can add 4 + 6 = 10 and 10 x 2 = 20 so that's our answer

Answer:

The height of the objects are the same after 2 seconds.

Step-by-step explanation:

In order to calculate at which time both objects have the same height we need to find the value of t that makes both equations equal. Therefore:

[tex]-t^2 + 3t = -t + 4\\t^2 - 3t - t + 4 = 0\\t^2 - 4t + 4 = 0\\t_{1,2} = \frac{-(-4) \pm \sqrt{(-4)^2 - 4*1*4}}{2*1} = \frac{4 \pm \sqrt{16 - 16}}{2}\\t_{1,2} = \frac{4}{2} = 2[/tex]

The height of the objects are the same after 2 seconds.

Answer:

C) The bars weigh 2.8oz on average.

Step-by-step explanation:

The fact that each sample's mean weight was within the 95% confidence interval suggests that the true mean weight of the chocolate bars is likely to be around 2.8 oz. The 95% confidence interval means that, in theory, if we repeated this sampling process many times, we would expect the true mean weight of the chocolate bars to fall within this interval 95% of the time. Since each sample's mean weight falls within this interval, it is reasonable to conclude that the company's claim that the bars weigh 2.8 oz on average is likely to be true.

Step-by-step explanation:

Explanation:-

Given circumference of cylinder A = π r² = 4π units

Given circumference of cylinder B = π r² = 9π units

The  dimensions of cylinder A are multiplied by [tex]\frac{9}{4}[/tex]

   circumference of cylinder A = π r² = 4π([tex]\frac{9}{4})[/tex] units     = 9 π units  

circumference cylinder A= 4π([tex]\frac{9}{4})[/tex] units = 9 π units = circumference of cylinder B

Final answer:-

The dimensions of cylinder A are multiplied by 9/4  produce the corresponding dimensions of cylinder B
