Answer:

James has an ice cube tray that makes ice in the shape of spheres rather than cubes. Each sphere of ice has a radius of 2 cm. One tray makes 6 spheres.What is the total volume of ice the tray can make at one time?

Total volume of the tray James have = 201.06 cm^3

Step-by-step explanation:

Given:

Radius of the spherical ice cube = 2 cm

No. of spheres in the ice cube = 6

We have to find the total volume of the ice tray that can make at one time.

Let the total volume be "V".

Formula to be used:

Volume of sphere =  [tex]\frac{4\pi r^3 }{3}[/tex]  cubic unit.

Total volume = [tex]n\times \frac{4\pi r^3 }{3}[/tex] cubic unit.

So,

Total volume of the ice tray (V) :

⇒ [tex]V=n\times \frac{4\pi r^3 }{3}[/tex]

⇒ Plugging n = 6 and r = 2

⇒ [tex]V=6\times \frac{4\pi (2)^3 }{3}[/tex]

⇒ [tex]V=6\times \frac{4\pi (8) }{3}[/tex]

⇒ [tex]V=6\times \frac{32\pi }{3}[/tex]

⇒ [tex]V=\frac{32\times 6\pi }{3}[/tex]

⇒ [tex]V=32\times 2\pi[/tex]

⇒ [tex]V=201.06\ cm^3[/tex]

So,

The total volume of ice the tray can make at one time = 201.06 cm^3

Answer: 24.5%

Step-by-step explanation:

Last year her stock in company A was worth $4600. If her Stock in company A has decreased by 25% since last year in stock, then the amount by which it decreased is

25/100 × 4600 = $1150

The present worth is

4600 - 1150 = $3450

Also, her stock in company B was worth $1000. If her Stock in company B has decreased by 22% since last year in stock, then the amount by which it decreased is

22/100 × 1000 = $220

The present worth is

1000 - 220 = $780

The total worth of both stocks last year was

4600 + 1000 = $5600

The total worth of both stocks this year was

3450 + 780 = $4230

The amount by which it decreased is

5600 - 4230 = 1370

the total percentage decrease in the investor stock account is

1370/5600 × 100 = 24.5%

Answer:

Step-by-step explanation:

Let x is the side of identical squares

By cutting out identical squares from each corner and bending up the resulting flaps, the dimension are:

The volume will be:

V = (10-2x) (10-2x) x

<=> V = (10x-2[tex]x^{2}[/tex]) (10-2x)

<=> V = 100x -20[tex]x^{2}[/tex] - 20[tex]x^{2}[/tex] + 4[tex]x^{3}[/tex]

<=> V = 4[tex]x^{3}[/tex]  - 40[tex]x^{2}[/tex] + 100x

To determine the dimensions of the largest box that can be made, we need to use the derivative and and set it to zero for the maximum volume

dV/dx = 12[tex]x^{2}[/tex] -80x + 100

<=>  12[tex]x^{2}[/tex] -80x + 100 =0

<=> x = 5 or x= 5/3  

You know 'x' cannot be 5 , because if  we cut 5 inch squares out of the original square, the length and the width will be 0. So we take x = 5/3

=>

To determine the dimensions of the largest box that can be made from a tin sheet, we need to find the side length of the square that will be cut out from each corner of the tin sheet. The dimensions of the largest box that can be made are approximately 6.67 inches by 6.67 inches by 1.67 inches.

To determine the dimensions of the largest box that can be made from a tin sheet, we need to find the side length of the square that will be cut out from each corner of the tin sheet. Let's assume the side length of the square to be x inches. The length and width of the resulting box will be 10 - 2x inches and 10 - 2x inches, respectively. The height of the box will be x inches. To find the dimensions of the largest box, we need to find the value of x that maximizes the volume of the box.

The volume of the box is given by V = (10 - 2x)(10 - 2x)(x). We can write this as V = 4x^3 - 40x^2 + 100x. To find the value of x that maximizes the volume, we can take the derivative of V with respect to x and set it equal to 0. Differentiating V, we get dV/dx = 12x^2 - 80x + 100. Setting this equal to 0 and solving for x, we find x = 1.67 inches (rounded to two decimal places). Therefore, the dimensions of the largest box that can be made are approximately 6.67 inches by 6.67 inches by 1.67 inches.

The original value of the house when it was purchased was $450,000.

Let us assume the original value of the house was x. This means that the house has increased by 38% from x to become $621,000.

In order to find the original value therefore, you can use the formula:

Original value + (Original value x Increase) = Current price

x + (38% × x) = 621,000

1.38x = 621,000

x = 621,000 / 1.38

= $450,000

In conclusion, the original value was $450,000.

Find out more at https://brainly.com/question/12980037.

Final answer:

The original purchase price of the house was $450,000.

Explanation:

To find the original value of the house before it increased in value, we must first understand that the current value represents 138% of the original value, since the house has increased in value by 38%. This is because the original value is 100%, and the increase is 38%, making the total 138%. Therefore, the equation to find the original purchase price (which we can call 'P') is:

P * 138% = $621,000

We can rewrite this as:

P * 1.38 = $621,000

To solve for P, we divide both sides of the equation by 1.38:

P = $621,000 / 1.38

Now, doing the division:

P = $450,000

So, the house was originally purchased for $450,000 before it increased by 38% to its current value of $621,000.

Answer:

Step-by-step explanation:

Well first you have to find what the total amount of all the interior angles. In Oder to do that you count how many sides the shape has the subtract two from that number. Take the number you get from that and multiply it by 180. That number is total amount of all the interior angles including the angle x. Take the angles you do know and add them together. Take the number you get from that and subtract it from the total amount of all interior angles. The number you get from that is your answer. The answer to this problem is 103.

The value of angle x in a pentagon is 103 degrees.

In a pentagon, the sum of the interior angles is always 540 degrees. To find the value of angle x, we can subtract the given angles from 540 degrees and then divide by the number of missing angles.

Given angles: 117, 100, 105, 115

Sum of given angles: 117 + 100 + 105 + 115 = 437 degrees

Sum of missing angles: 540 - 437 = 103 degrees

Since there is only one missing angle x in the pentagon, the value of x must be 103 degrees.

Answer:

The probability that a randomly selected student has dark hair, given that the student has blue eyes is 43%.

Step-by-step explanation:

Conditional probability:

Let A and B any two events connected to a given random experiment E. The conditional probability of the event A on the hypothesis that the event B has occurred, denoted by P(A|B), is defined as

[tex]P(A|B)=\frac{P(A\cap B)}{P(B)}[/tex]

Given that,

In a city school, 70% of students have blue eyes, 45% have dark eyes and 30% have blue eyes and dark hair.

A= students have blue eyes

B= Students have dark hair.

P(A)= 70% [tex]=\frac{70}{100}[/tex] [tex]=\frac7{10}[/tex]

P(B)=45% [tex]=\frac{45}{100}[/tex] [tex]=\frac9{20}[/tex]

P(A∩B)=30%[tex]=\frac{30}{100}[/tex] [tex]=\frac3{10}[/tex]

∴P(B|A)

[tex]=\frac{P(A\cap B)}{P(A)}[/tex]

[tex]=\frac{0.3}{0.7}[/tex]

[tex]=\frac37[/tex]

=0.429

=0.429×100 %

≈43%

The probability that a randomly selected student has dark hair, given that the student has blue eyes is 43%.

In hypothesis testing for this scenario, the null hypothesis (H-0) is that the proportion of rejected screens remains 12 percent (H-0: p = 0.12). The alternative hypothesis (Ha) is that the proportion of rejected screens is less than 12 percent (Ha: p < 0.12). A sample is taken and a significance test (such as a z-test for proportion) is conducted to decide if the null hypothesis can be rejected.

The question is looking for you to conduct a hypothesis test to investigate whether a new process in manufacturing cell phone screens has led to a reduced proportion of rejected screens. When conducting such a hypothesis test, you'll need to consider a null hypothesis and an alternative hypothesis.

The null hypothesis (H-0) is often the initial claim about a population proportion. In this case, the null hypothesis would be that 12 percent of the screens (0.12) are still being rejected: H-0: p = 0.12.

The alternative hypothesis (Ha) is what you might believe to be true if the null hypothesis is proven to be incorrect. Here, the alternative hypothesis would be that less than 12 percent of screens are being rejected with the new process: Ha: p < 0.12.

To clarify, if the new process is effective, a lower proportion of screens should be rejected. Thus, the hypotheses to be tested are:

Lastly, after selecting the sample, compute the sample proportion. Here a total sample size of 100 screens with only 6 being rejected means the sample proportion (p) = 6/100 = 0.06.

From here, you would proceed to conduct a significance test (possibly a z test for proportion) and determine a p-value to make a decision regarding the null hypothesis.

Answer:

0.3694

Step-by-step explanation:

In this question, we are asked to calculate the probability that a golfer scored at least 74 if she played on a particular day.

Given that ,

mean = µ = 73

standard deviation = σ = 3

P(x > 74) = 1 - P(x<74 )

= 1 - P[(x -µ) / σ < (74 -73) /3 ]

= 1 - P(z <0.3333 )

Using z table

= 1 - 0.6305

= 0.3694

probability= 0.3694

To find the probability of a golfer scoring at least 74 on a course with a mean score of 73 and a standard deviation of 3, we calculate the z-score for 74, find the corresponding probability in the z-table, and subtract this from 1 to get the upper tail probability. The probability is approximately 37%.

The score of golfers for a particular course follows a normal distribution that has a mean of 73 and a standard deviation of 3. We want to find the probability that a golfer scores at least 74. This is a question of statistics and specifically involves the concept of the normal distribution and calculating z-scores.

Firstly, we need to calculate the z-score for the score of 74. The z-score is calculated as (X-μ)/σ, where X is the score we are interested, μ is the mean, and σ is the standard deviation. Substituting the given values, (74 - 73) / 3 gives a z-score of approximately 0.33.

Then, to find the probability that a score is at least 74, we need to find the proportion of data to the right of this z-score in a standard normal distribution. This is known as the 'upper tail'. We subtract the z-score from 1 because the total probability under the normal curve is 1. If we look up 0.33 in the z-table, we get a value of 0.6293. Subtracting this value from 1 gives us 0.3707.

Therefore, the probability that a golfer scores at least 74 on this course is approximately 0.37 or 37%.
