Answer:

680

Step-by-step explanation:

Use the binomial coefficient where you choose [tex]k=3[/tex] numbers out of [tex]n=17[/tex] possible numbers and find the total amount of combinations since order does not matter:

[tex]\displaystyle \binom{n}{k}=\frac{n!}{k!(n-k)!}\\ \\\binom{17}{3}=\frac{17!}{3!(17-3)!}\\\\\binom{17}{3}=\frac{17!}{3!(14)!}\\\\\binom{17}{3}=\frac{17*16*15}{3*2*1}\\\\\binom{17}{3}=680[/tex]

Thus, you can make 680 three-non-repeating-number codes

Answer:

700π m ~ 2199 m

Step-by-step explanation:

diameter = d = 200 m

2 min 20s = 140 s

1 round / 40 s

140 = 40 * 3 + 20

so the athlete will cover 3 round and half

1 round = d * π

covered = c = 3 * 200 * π + 200/2 * π = 700 * π

Two or more angles whose sum is 180° are called supplementary angles. The measure of the ∠y is 120°.

Two or more angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. That means, that if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.

Given the puck strikes the wall at an angle of 30°, it goes away at the same angle of 30°. Therefore, the measure of angle y can be found using the sum of the angle as a supplementary angle. Thus, we can write,

30° + ∠y + 30° = 180°

60° + ∠y = 180°

∠y = 180° - 60° = 120°

Hence, the measure of the ∠y is 120°.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per cent refers to one hundred percent.

The cost will be  £17 according to the question

Total  amount generated are;

32 cans * £0.50=£16

18 cans * £0.20=£3.60

Based on the calculations, the two (2) statements which are true are:

Mathematically, range can be calculated by using this formula;

Range = Highest number - Lowest number

Range 1 = 71 - 32

Range 1 = 39.

Range 2 = 71 - 3

Range 2 = 68.

Therefore, the range of Data Set 2 is not smaller than the range of Data Set 1.

Mathematically, the mean for these data sets would be calculated by using this formula:

Mean = [F(x)]/n

For the total number of Data Set 1, we have:

F(x) = 32 + 41 + 51 + 63 + 66 + 71

F(x) = 324.

Substituting the parameters into the formula, we have:

Mean = [F(x)]/n

Mean 1 = [324]/6

Mean 1 = 54.

For the total number of Data Set 2, we have:

F(x) = 32 + 41 + 51 + 3 + 66 + 71

F(x) = 324.

Substituting the parameters into the formula, we have:

Mean 2 = [264]/6

Mean 2 = 44.

Difference = Mean 1 - Mean 2

Difference = 54 - 44

Difference = 10.

Therefore, the mean of Data Set 2 is exactly 10 less than the mean of Data Set 1.

For the standard deviation of Data Set 1, we have:

SD₁ = √(1/n × ∑(xi - u₁)²)

SD₁ = √(1/5 × ∑(32 - 54)² + 1/5 × ∑(41 - 54)² + 1/5 × ∑(51 - 54)² + 1/5 × ∑(63 - 54)² + 1/5 × ∑(66 - 54)² + 1/5 × ∑(71 - 54)²)

SD₁ = 15.34.

For the standard deviation of Data Set 2, we have:

SD₂ = √(1/n × ∑(xi - u₂)²)

SD₂ = √(1/5 × ∑(32 - 44)² + 1/5 × ∑(41 - 44)² + 1/5 × ∑(51 - 44)² + 1/5 × ∑(3 - 44)² + 1/5 × ∑(66 - 44)² + 1/5 × ∑(71 - 44)²)

SD₂ = 24.88.

Therefore, the standard deviation of Data Set 2 is larger than the standard deviation of Data Set 1.

Answer:

Step-by-step explanation:

Understanding the situation

Parallel lines have the same slopes.

If line t is parallel to line u then the slope of line t is the same as the slope of line u.

Finding the slope of line t

Slope formula = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

where the x and y values are derived from points on the line

here, we are given that line to goes through (2,2) and (10,9)

Given that we can assign variables

we have (x1,y1) = (2,2) so x1 = 2 and y1 = 2

we also have (x2,y2) = (10,9) so x2 = 10 and y2 = 9

Now that we have assigned variables we plug them into the formula

Recall formula : [tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

==> plug in x1 = 2 , y1 = 2, x2 = 10 and y2 = 9

[tex]slope =\frac{9-2}{10-2}[/tex]

==> simplify top and bottom

[tex]slope =\frac{7}{8}[/tex]

The slope of line t is 7/8

Finding the slope of line u

Because line t and line u are parallel line u also has a slope of 7/8

Start at (0,1) and then go up 4 spaces over 1 to the left and repeat going up 4 over 1. To complete the graph by getting it to go behind the y intercept of (0,1) you go from the y intercept down 4 over 1 to the right and repeat going down 4 over 1.

For plotting a line, we need to plot points [tex](0,1)[/tex] and [tex](\frac{-1}{4},0)[/tex] on the cartesian plane and join them to form a line.

For plotting a line, we only need two points to graph a line. With that idea, we take advantage of the two “convenient” points which can easily be solved algebraically from the equation of the line; namely, the x-intercept (x,0) and y-intercept (0,y).

[tex]y = 4x + 1\\\\Put\ x = 0 \\y = 1\\we\ get\ (0,1)\ as\ a\ point\ lying\ on\ the\ line. \\\\Put\ y = 0 \\x = \frac{-1}{4} \\we\ get\ (\frac{-1}{4} ,0)\ as\ a\ point\ lying\ on\ the\ line. \\[/tex]

Enough to cover the seat

Step-by-step explanation: If this is a question dealing with the area of said object (seat) simply make an equation to find the area of your object.  So let's say we got a seat that is 4 feet wide and 6 feet tall.

We will multiply 4 feet times 6 feet and that's where we get 24 feet.

So we know how many inches are in a feet right, there are 12 inches per foot. So 12 time 24 is our problem 12 x 24 = 288 inches. So we would need enough stain to cover 288 inches .

Answer: 7cm

Step-by-step explanation:

Use pythagorean theorum:

Variables:

Let the edge = A

Face diagonal (F) = 10cm

Inner diagonal (I) = sqrt(150) cm

A^2 = I^2 - F^2

A^2 = [sqrt(150)]^2 - 10^2

A^2 = 150 - 100

A^2 = 50

A = sqrt(50)

A = 7.0710678 cm

A = 7cm (to the nearest tenth)

so, length of an edge = 7cm

Answer:

So we must determine the distance between our two given points and that can be found using the distance formula [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex].

Plugging the values into the equation and solve

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]d=\sqrt{(-9-5)^2+(-2-6)^2}[/tex]

[tex]d=\sqrt{(-14)^2+(-8)^2}[/tex]

[tex]d=\sqrt{196+64}[/tex]

[tex]d=\sqrt{260}[/tex]

[tex]d=16.125\ units[/tex]

Therefore, our final answer is that the distance is 16.125 units

Using the z-distribution, it is found that the margin of error for the 95% confidence interval is of 0.117.

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

The margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In this problem, we have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

The sample size and the estimate are given as follows:

[tex]n = 45, \pi = \frac{9}{45} = 0.2[/tex]

Hence the margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
