I put the question in the photo but it’s basically a contingency table I just can’t find which like formula to us

Answers

a) The probability that exactly one of them will be a girl = 0.3407

b) The probability that at least one of them will like the football = 0.7672

a) If we select three students then the probability that exactly one of them will be a girl

From the attached two way table we can observe that the total number of girls = 22

the total number of boys = 18

and the total number of students = 40

The possible outcomes for selecting 3 students from 40 would be,

⁴⁰C₃

Using combination formula,

⁴⁰C₃ = 40! / (3! × (40 - 3)!)

      = 9880

If there is exactly one girl then other two must be boys in the set of 3 selected students.

So, the required probability would be,

P = (²²C₁ × ¹⁸C₂) / ⁴⁰C₃

P = (22 × 153)/9880

P = 0.3407

b) The number of students like the football = 15

and the number of students who don't like the football are 40 - 15 = 25

The probability that at least one of them will like the football would be,

P = (¹⁵C₃ × ²⁵C₀ + ¹⁵C₂ × ²⁵C₁ + ¹⁵C₁ × ²⁵C₂) / ⁴⁰C₃

P = ((455 × 1) + (105 × 25) + (15 × 300)) / 9880

P = 0.7672

0.33
0.02

Answers

The required experimental probability that a team will consist entirely of boys is 0.04. Option B is correct.

To find the experimental probability that a team will consist entirely of boys, we need to count the number of trials in which all three coin tosses resulted in tails (which represents a team consisting entirely of boys), and divide by the total number of trials (which is 50).

From the data, we can see that there are only 2 trials where all three coin tosses resulted in tails, so the experimental probability of a team consisting entirely of boys is:

2/50 = 0.04

Therefore, the experimental probability that a team will consist entirely of boys is 0.04.

For which distribution is the mode the best measure of center?
A. Skewed
B. Normal
C. Biomodal

Answers

Answer:

The mode is the best measure of center for a distribution that is bimodal, meaning that it has two peaks. In such a distribution, the mean and median may not be representative of the center of the data, but the mode is a good measure of center because it reflects the most common value(s) in the data.

For skewed distributions, the mode may not be a good measure of center because the peak of the distribution is not necessarily at the center of the data. In a normal distribution, the mean, median, and mode are all equal and are good measures of center.

Enter your answer by filling in the boxes. Enter coordinates as simplifed fractions or radicals in simplest form.

( , )

Answers

Answer:

(10, 5π/3)

Step-by-step explanation:

To convert rectangular coordinates (5, -5√3) to polar form, we can use the following formulas:

r = √(x^2 + y^2)

θ = arctan(y/x)

Substituting the given values, we get:

r = √(5^2 + (-5√3)^2) = √(25 + 75) = √100 = 10

θ = arctan((-5√3)/5) = arctan(-√3) = -π/3

Note that the value of θ is in the fourth quadrant, which corresponds to a negative angle. However, we need to express the angle θ in the range 0 ≤ θ < 2π. To do this, we can add 2π to the angle if it is negative:

θ = -π/3 + 2π = (5π/3)

Therefore, the rectangular coordinates (5, -5√3) in polar form are (10, 5π/3).

Answer: the area of the triangle is 150 cm².

Step-by-step explanation:

To solve this problem, we need to use the formula for the area of a triangle:

Area = (1/2) x base x height

From the diagram, we can see that the base of the triangle is 20 cm and the height is 15 cm. Plugging these values into the formula, we get:

Answers

The money invested by the teacher to have at least 125,000 in her account after 40 years of a 6.95% annual interest rate compounded continuously is 7755. Hence, the right solution to the question is option D

Compound interest is given by

A = P[tex](1+r)^t[/tex]

where A is the amount

P is the principal

r is the rate of interest

t is the time

Given in the question,

A = $125,000

r = 6.95% or 0.0695

t = 40 years

P is to be found

A = P[tex](1+r)^t[/tex]

125000 = P [tex](1 + 0.0695)^{40[/tex]

125000 = P * [tex]1.0695^{40[/tex]

The function f(x) = 1.85x2 models the cost of a square carpet, where x is the length in feet. Find the average rate of change for f, to the nearest tenth, over the interval 10 ≤ x ≤ 20.

Answers

To find the average rate of change of the function f(x) = 1.85x^2 over the interval 10 ≤ x ≤ 20, we need to find the difference in the function values at the endpoints of the interval and divide by the length of the interval.

The function value at x = 10 is:

f(10) = 1.85(10)^2 = 185

The function value at x = 20 is:

f(20) = 1.85(20)^2 = 740

The length of the interval is:

20 - 10 = 10

So the average rate of change of the function over the interval 10 ≤ x ≤ 20 is:

(f(20) - f(10)) / (20 - 10) = (740 - 185) / 10 = 55.5

Rounding to the nearest tenth, the average rate of change of the function over the interval 10 ≤ x ≤ 20 is approximately 55.5.

Find (g of (26) when f(x) = X-2 and g(x) = 7x + 2.
A) "
B) 54
C) 44
D) 1104

Answers

Answer:

To find g(26) when g(x) = 7x + 2, we simply need to substitute x = 26 into the expression for g(x):

g(26) = 7(26) + 2

g(26) = 184

Now, to find (g of f)(x), we need to substitute f(x) into the expression for g(x):

(g of f)(x) = g(f(x)) = 7(f(x)) + 2

Since f(x) = x - 2, we can substitute x - 2 for f(x) in the expression for g(x):

(g of f)(x) = g(x - 2) = 7(x - 2) + 2

Simplifying this expression, we get:

(g of f)(x) = 7x - 12

Now, to find (g of f)(26), we simply substitute x = 26 into the expression we just found:

(g of f)(26) = 7(26) - 12

(g of f)(26) = 182

It is estimated that the cost of raw materials will increase by 20%, the labour cost will increase by 10%, 50% of the overhead charges are fixed and the other 50% are variable. The selling expenses per unit will be reduced by 20%. The rate of profit will remain the same. Prepare a cost statement for the year 2021 showing the total profit and selling price per unit.​

Answers

Answer:

Here's a cost statement for the year 2021:

Production of 1,500 units

Cost of raw materials = Rs. (20,000 x 1.2) = Rs. 24,000

Labour cost = Rs. (12,000 x 1.1) = Rs. 13,200

Fixed overheads = Rs. (8,000/2) = Rs. 4,000

Variable overheads = Rs. (8,000/2 x 1.5) = Rs. 6,000

Office overheads = Rs. 4,000

Selling expenses per unit = Rs. (1,000 x 0.8 / 1,500) = Rs. 0.53

Total cost per unit = Rs. (24,000 + 13,200 + 4,000 + 6,000 + 4,000) / 1,500 = Rs. 28.80

Profit = 25% of selling price

Selling price per unit = (28.80 / (1 - 0.25)) = Rs. 38.40

Total profit = (1,500 x 38.40 x 0.25) = Rs. 14,400

Therefore, the cost statement for the year 2021 shows a total profit of Rs. 14,400 and a selling price per unit of Rs. 38.40.

In this scenario, the relative humidity would be plotted on the x-axis (x-coordinate) of the scatter plot while the heat index would be plotted on the y-axis (y-coordinate) of the scatter plot through the use of Microsoft Excel.

From the scatter plot which models the relationship between the x-values and y-values, a quadratic equation for the line of best fit when the temperature outside is 86°F, is given by:

y = 0.004x²- 0.1243x + 84.028

when x = 55%, the heat index can be calculated as follows;

y = 0.004(55)²- 0.1243(55) + 84.028

of his book are sold at $29.50 each, how
much does Professor Snozz make?

Answers

If professor Snozz earns 8% of "total-sales", then the amount that the professor make on selling of 300 copies is $708.

In order to find out how much Professor Snozz makes, we first calculate the "total-sales" revenue of the 300 copies of the book;

⇒ Total sales revenue = (number of copies sold) × (price per copy),

⇒ Total sales revenue = 300 × $29.50,

⇒ Total sales revenue = $8850;

Next, we calculate amount of royalty that Professor Snozz earns, which is 8% of the total sales revenue;

So, Royalty = 8% of "Total sales revenue";

⇒ Royalty = 0.08 × $8850,

⇒ Royalty = $708;

Therefore, Professor Snozz earns $708 as a royalty for selling 300 copies of his book.

Amir's average speed for the whole journey was 51 km/h.

We have,

Let the total distance between Town A and Town B be D.

According to the problem,

Amir traveled 1/5 of the journey in the first two hours, which means he covered a distance of D/5 in 2 hours.

The remaining distance is 4D/5.

He then traveled 1/3 of the remaining journey in the next one hour, which means he covered a distance.

= (1/3) × (4D/5)

= 4D/15 in the next hour.

Therefore, the remaining distance.

= 4D/5 - 4D/15

= 8D/15.

It took him another 2 hours to cover the remaining distance of 136 km, so we have:

8D/15 = 136 km

Solving for D.

D = (136 km)×(15/8)

= 255 km

Therefore,

The total distance between Town A and Town B is 255 km.

The total time Amir took for the journey is 2 + 1 + 2 = 5 hours.

His average speed for the whole journey.

Step 1:

Let the cost of a football be [tex]f[/tex]and the cost of a tennis ball be [tex]t[/tex].

Step 2:

Write the 2 equations we have from the given information:

Find the 36th term.
5, 8, 11, 14, 17, ...
36th term = [?

Answers

Answer:

110

Step-by-step explanation:

nth term = 3n + 2

3 (36) + 2

108 + 2 = 110

Answer:

The 36th term in the sequence is 104.

Here's how to find it:

- Start with the first number in the sequence: 5.

- Add the common difference, which is 3, to get the second number in the sequence: 8.

- Add the common difference to the second number to get the third number: 11.

- Continue adding the common difference to each subsequent number to find the next term in the sequence.

- The 36th term is three less than 37 times the common difference added to the first term.

- Using that formula, we can calculate the 36th term as: 5 + (36 - 1) * 3 = 5 + 105 = 110.

- Therefore, the 36th term in the sequence is 104.

A man earns $65000. He pays 18% of that in tax. (a) Calculate how much he has left, after paying the tax. (b) He invests $4500 and earns 6% interest per annum. Calculate the interest after 2 years. (c) He takes out a loan to buy a car. The price of the car is $24750. He pays $25740 altogether. What is the percentage interest?

Answers

a) The amount left after paying the tax is $53300.

(b) The interest after 2 years is $540.

(c) The percentage interest is 4%.

We have,

a)

The amount of tax the man pays.

= $65000 x 0.18

= $11700

Therefore, he has left.

= $65000 - $11700

= $53300

(b)

The interest earned after 2 years.

= $4500 x 0.06 x 2

= $540

(c)

The total amount of interest paid on the loan.

= $25740 - $24750

= $990

The percentage interest.

= ($990 / $24750) x 100%

= 4%

Thus,

(a) The amount left after paying the tax is $53300.

(b) The interest after 2 years is $540.

(c) The percentage interest is 4%.

Which of the following points are on the line given by the equation y = x? Check all that apply. A. (3, 6) B. (4, 2) C. (3, 15) D. (-2, 1) E. (2, 1) F. (-2, -1)

Answers

Answer:

The points that are on the line given by the equation y = x are:

A. (3, 3)

B. (2, 2)

D. (-1, -1)

E. (1, 1)

To check if a point is on the line, you can substitute its coordinates into the equation and see if the equation is true. For example, for point (3, 6), we have:

y = x

6 = 3

This is not true, so the point (3, 6) is not on the line. Repeat this process for each point to determine which points are on the line.

x = 16 and y = 2, given that x is directly related to the square of y. If x = 100, what is one possible value of y?

Answers

Answer: 5

Step-by-step explanation:

Since x is directly related to the square of y, we can write the equation:

x = ky^2

where k is a constant of proportionality. We can solve for k using the given values of x and y:

16 = k(2^2) -> 16 = 4k -> k = 4

Now that we know k, we can use it to find y when x = 100:

100 = 4y^2 -> 25 = y^2 -> y = ±5

Since y cannot be negative, the only possible value of y is 5. Therefore, when x = 100, y could be 5.

Answer:

One possible value of y when x = 100 is y = 5.

Step-by-step explanation:

Using the direct variation formula, we know that x = ky^2, where k is a constant. Given that x = 16 and y = 2, we can solve for k:

16 = k(2)^2

k = 4

Now we can use this value of k to find y when x = 100:

100 = 4y^2

y^2 = 25

y = 5 or -5 (since the question only asks for one possible value, we can choose either solution)

Therefore, one possible value of y when x = 100 is y = 5.

What is the image point of (-7,-8)after the transformation D1/2oT-1,0?

Answers

The image point of (-7,-8) after the transformation D1/2oT-1,0 is (-4,4).

First, we apply the translation T-1,0, which moves every point 1 unit to the right (since the x-coordinate is decreased by 1) and leaves the y-coordinate unchanged. Therefore, the image of (-7,-8) under T-1,0 is (-7-1,-8) = (-8,-8).

Next, we apply the dilation D1/2, which scales every distance from the origin by a factor of 1/2. Therefore, the image of (-8,-8) under D1/2 is (-8/2,-8/2) = (-4,-4).

Thus, the image point of (-7,-8) after the transformation D1/2oT-1,0 is (-4,4).
