Answer:

0.1835

Step-by-step explanation:

This question can be solved by way of binomial distribution.

Let’s have the probability of success as p which is the probability that they stay with the company for more than five years;

p = 8/100 = 0.08

probability of failure, meaning not staying is q = 1-p = 1-0.08 = 0.92

Now let’s write the expression for the binomial distribution. That would be;

probability = 12C2 * 0.08^2 * 0.92^10

= 0.1835

Probabilities are used to determine the chances of an event.

The probability that exactly two stays more than 5 years is 0.1835

The given parameters are:

[tex]\mathbf{n = 12}[/tex] ---- sample

[tex]\mathbf{x = 2}[/tex] --- selected

[tex]\mathbf{p = 80\%}[/tex] --- sample proportion

So, the probability that exactly two stays more than 5 years is calculated using the following binomial probability:

[tex]\mathbf{P(x) = ^nC_x p^x (1 - p)^{n -x}}[/tex]

So, we have:

[tex]\mathbf{P(x) = ^{12}C_2 (8\%)^2 (1 - 8\%)^{12 -2}}[/tex]

[tex]\mathbf{P(x) = ^{12}C_2 (8\%)^2 (92\%)^{10}}[/tex]

Solve 12C2 using a calculator

[tex]\mathbf{P(x = 2) = 66 \times (8\%)^2 \times (92\%)^{10}}[/tex]

[tex]\mathbf{P(x = 2) = 0.1835}[/tex]

Hence, the probability that exactly two stays more than 5 years is 0.1835

The gradient of the line that is perpendicular to the line 2y = 3 + 5x is found to be -0.4, after converting the given equation to slope-intercept form and determining the negative reciprocal of the original slope.

To find the gradient of a line that is perpendicular to the given line 2y = 3 + 5x, we first need to put the given equation in slope-intercept form (y = mx + b). By dividing everything by 2, we get y = 2.5x + 1.5, where the gradient (or slope) of this line is 2.5. Since perpendicular lines have slopes that are negative reciprocals of each other, the slope of the line perpendicular to the given one is -1/2.5, which simplifies to -0.4. Therefore, the gradient of the line that is perpendicular to the line 2y = 3 + 5x is -0.4.

Answer:

The population of city Y is 20 times than that of city X.

Step-by-step explanation:

Given:

City X has a population of 3 times 10^5

City Y has a population of 6 times 10^6.

Question asked:

Which statement correctly describes the relationship between the population of city X and city Y?

Solution:

If we will be able to find the number of times the population of city Y more than that of city X, it will be the best and easy to understand relationship between the population of these two towns:

And we can easily calculate by dividing the population of city Y by population of city X.

[tex]=\frac{6\times10^{6} }{3\times10^{5}} \\ \\ =\frac{6\times10^{6-5} }{3}\ (\frac{a^{m} }{a^{n} }= a^{m-n} )[/tex]

[tex]=\frac{6\times10^{1} }{3} \\ \\ =\frac{60}{3} \\ \\ =20\ times[/tex]

Thus, the population of city Y is 20 times than that of city X.

City Y's population is 20 times larger than that of city X. This is determined by dividing City Y's population by City X's.

The relationship between the populations of city X and city Y can be understood by comparing the numbers provided: 3 times 10^5 (or 300,000) for city X and 6 times 10^6 (or 6,000,000) for city Y. It's clear that city Y has a significantly larger population. In fact, city Y's population is 20 times larger than that of city X.

This is calculated by dividing city Y's population (6,000,000) by city X's population (300,000), getting the result 20.

Step-by-step explanation:

But lets not quote me on that. :]

Answer:

Step-by-step explanation:

We would determine the mean an standard deviation first

Mean = (107 + 92 + 97 + 95 + 105 + 101 + 91 + 99 + 95 + 104)/10 = 98.6

Standard deviation = √(summation(x - mean)/n

n = 10

Summation(x - mean) = (107 - 98.6)^2 + (92 - 98.6)^2 + (97 - 96.6)^2 + (95 - 98.6)^2 + (105 - 98.6)^2 + (101 - 98.6)^2 + (91 - 98.6)^2 + (99 - 98.6)^2 + (95 - 98.6)^2 + (104 - 98.6)^2 = 274

Standard deviation = √(274/10) = 5.23

The confidence interval is used to determine the range of values that could possibly contain a population parameter (population mean)

Confidence interval is written in the form,

(Point estimate - margin of error, Point estimate + margin of error)

The sample mean, x is the point estimate for the population mean.

We will use the t distribution because the sample size is small and the population standard deviation is not given.

Degree of freedom, df = 10 - 1 = 9

α = 1 - 0.99 = 0.01

z α/2 = 0.01/2 = 0.005

The area to the right of z 0.005 is 0.005 and the area to the left of z0.005 is 1 - 0.005 = 0.995. Using the t distribution table,

z = 3.25

Margin of error = z × s/√n

Where

s = sample standard Deviation = 5.23

Margin of error = 3.25 × 5.23/√10 = 5.38

Confidence interval = sample mean(point estimate) ± z × σ/√n

The lower boundary of the confidence interval is

98.6 - 5.38 = 93.22

The upper boundary of the confidence interval is

98.6 + 5.38 = 103.98

We estimate with 99% confidence that the mean weekly child care cost of their employees is between $93.22 and $103.98

Also,

99% of the confidence intervals constructed in this way would contain the true value for the population mean of mean weekly child care cost of their employees.

The 99% confidence interval for the average weekly childcare cost based on this sample data is [$94.6, $102.6], which means we're 99% certain the true average cost falls within this range.

When we are talking about a confidence interval for the population mean, we're trying to determine a range within which we're confident the true average child care cost falls, given the data we have from a sample of employees. To do this, we first have to calculate the mean (or average) child care cost and the standard deviation of our sample.

The mean weekly child care cost would be ($107 + $92 + $97 + $95 + $105 + $101 + $91 + $99 + $95 + $104) / 10 = $98.6. To calculate the standard deviation, you would subtract each data point from the mean, square the results, find the average of these squared differences, and finally take the square root. In this case, the standard deviation equates to ~5.27. Now we can use these values to calculate the confidence interval. For a 99% confidence interval with a sample size of 10, the appropriate t-value from the t-distribution table is 3.25. The confidence interval would therefore be Mean +/- t-value*(standard deviation/sqrt(n)). So the interval would be 98.6 +/- 3.25*(5.27/sqrt(10)). This calculates to an interval of [94.6, 102.6]. That means we're 99% confident the true average weekly child care cost falls between $94.6 and $102.6.

Let x represent time taken by 20 members to paint 9000 square foot wall.

We have been given that all members of our painting team paint at the same rate. 20 members can paint a 6000 square foot wall in 24 minutes. We are asked to find the time taken by 20 members to paint 9000 square foot wall.

We will use proportions to solve our given problem.

[tex]\frac{\text{Time taken}}{\text{Area of wall painted}}=\frac{24\text{ min}}{6000\text{ ft}^2}[/tex]

[tex]\frac{x}{9000\text{ ft}^2}=\frac{24\text{ min}}{6000\text{ ft}^2}[/tex]

[tex]\frac{x}{9000\text{ ft}^2}\times 9000\text{ ft}^2=\frac{24\text{ min}}{6000\text{ ft}^2}\times 9000\text{ ft}^2[/tex]

[tex]x=\frac{24\text{ min}}{6}\times 9[/tex]

[tex]x=4\text{ min}\times 9[/tex]

[tex]x=36\text{ min}[/tex]

Therefore, it will take 36 minutes for 20 members to paint 9000 square foot wall.

Answer:

36 minutes

Step-by-step explanation:

The amount of time needed and the amount of wall to paint are directly proportional. So, when we multiply the amount of wall to paint by 4/3 (going from 6000 square feet to 9000 square feet), we multiply the time needed by 9000/6000 = 3/2. Therefore, the 20 members need 24 * 3/2 = 36 minutes to paint the 9000 square foot wall.

Answer:

Minimum number of pennies = 10

Step-by-step explanation:

Given:

Maximum number of coins Hannah have = 25

Total number of of nickels (coins) she has = 11

Total value of the combined coins = $ 0.65

We have to find the minimum number of pennies.

Let the number of pennies be "p"  and no. of nickels be "n".

Note:

Value of 1 penny = $ 0.01

Value of 1 nickel = $ 0.05

Arranging the above situation in terms of equations:

According to their quantities.

⇒ [tex]n+p\leq 25[/tex]  and [tex]11+p\leq 25[/tex] so [tex]p\leq 14[/tex]

According to their values.

⇒ [tex]0.05(n)+0.01(p)\leq \$\ 0.65[/tex]

⇒ [tex]0.05(11)+0.01(p)\leq \$\ 0.65[/tex]

⇒ [tex]\$\ 0.55+0.01(p)\leq \$\ 0.65[/tex]

⇒ [tex]0.01(p)\leq \$\ 0.65-\$\ 0.55[/tex]

⇒ [tex]0.01(p)\leq \$\ 0.10[/tex]

⇒ [tex](p)\leq\frac{ \$\ 0.10}{0.01}[/tex]

⇒ [tex](p)\leq 10[/tex]

Minimum number of pennies :

⇒ [tex](p)\leq 10[/tex] which also satisfies [tex]p\leq 14[/tex]

Therefore :

⇒ [tex]p=10[/tex]

Plugging p= 10 we can verify the values.

⇒ [tex]0.05(11)+0.01(10)\leq \$\ 0.65[/tex]

⇒ [tex]0.55+0.10\leq \$\ 0.65[/tex]

⇒ [tex]\$\ 0.65\leq \$\ 0.65[/tex]

So,

Minimum number of pennies Hannah have = 10

Final answer:

Hannah can have a minimum of 10 pennies along with her 11 nickels to make at least $0.65, while having a maximum of 25 coins in total.

Explanation:

Hannah has a maximum of 25 coins and among them, she has 11 nickels. Since she has a minimum combined worth of $0.65, we can calculate the minimum number of pennies she could have. One nickel is worth $0.05, so 11 nickels have a combined worth of $0.55 (11 times $0.05). To reach at least $0.65, we need at least $0.10 more.

A penny is worth $0.01, so to make up the additional $0.10, Hannah would need a minimum of 10 pennies. Therefore, with 11 nickels already accounted for, and the rest being pennies to reach $0.65, Hannah could have a minimum of 10 pennies. She cannot have more than 25 coins in total, so the number of pennies must also not exceed the limit of 25 total coins when added to the number of nickels she has. Since 11+10=21, this is less than the maximum of 25 coins, and thus, it is possible for Hannah to have a minimum of 10 pennies.

The height of the pyramid is 11 cm.

Step-by-step explanation:

We are given the following in the question:

Volume of triangular pyramid = 110 cubic cm

Base of trianle,b = 10 cm

Height of triangle,h = 6 cm

Area of triangular base =

[tex]A = \dfrac{1}{2}\times b\times h\\\\A = \dfrac{1}{2}\times 10\times 6\\\\A = 30\text{ square cm}[/tex]

Volume of triangular pyramid =

[tex]V = \dfrac{1}{3}AH[/tex]

where H is the height of the pyramid, A is the area of triangular base.

Putting values, we get,

[tex]110 = \dfrac{1}{3}\times 30\times H\\\\H = \dfrac{3\times 110}{30}\\\\H = 11\text{ cm}[/tex]

Thus, height of the pyramid is 11 cm.

The circumference of Cole's bass drum is 25.12 inches.

The formula to find the circumference (C) of a circle is C = 2πr, where r is the radius and π is approximately 3.14.

Since Cole's bass drum has a radius of 4 inches, we substitute the values into the formula to get

C = 2 × 3.14 × 4 inches.

So, the circumference of Cole's drum is C = 2×3.14 × 4 = 25.12 inches.

From what we know about percentages and unit rates, the correct options are:

1) 100

2) 1

Suppose we have an amount A, this would be the 100%.

If we want to know how much a quantity B represents, compared to A, we have:

A = 100%

B = x

where x is a percentage, to find the value of x we compute:

x = (B/A)*100%

While there is a dependence on A, we actually are comparing the term with 100 (because A represents a 100%), so the correct option is A: 100.

We define the unit rate as the rate for a unit of something.

for example, if we know that

2 apples cost $3

The unit rate per apple is:

U = $3/2 = $1.5

Meaning that each apple costs $1.5

So to get the unit rate, we need to compare the first term with 1 (a unit). So the correct option is D.
