Answer:

45

Step-by-step explanation:

To answer this question we will have to use the combination formula.

C(n,r) = n!/(n-r)!r!

n = population set = 10

e = sample set = 8 questions

Inserting into the formula we have:

10!/(10-8)!8!

= 3628800/2x40320

= 3628800/80640

= 45

So in conclusion, we have 45 combinations in existence that would yield 8 correct questions

Answer:

Step-by-step explanation:

When you add integers you have either positive integers or negative integers. When you add positive integers, you just add normal. When you have negative integers, you have to see if the the larger number is positive or negative that will tell you if your answer is either negative or positive. Then you turn the negative into a positive then change the addition sign to a subtraction sign then solve.

Answer:

w = 42

Step-by-step explanation:

A linear pair is a pair of adjacent angles which add up to 180 degrees(supplimentary).

Given m<1 = w + 5, m<2 = 3w + 7, and the fact that m<1, and m<2 form a linear pair. This relationship can be given by:

m<1 + m<2 = 180.

To solve just substitute the expressions given by the angles, and solve.

m<1 + m<2 = 180

Answer:Best corral has a width and length of 50 feet, enclosing an area of 2500 square feet. Let's calculate the width (W) of the rectangle as a function of it's length (L). So we have W = (200 - 2*L)/2 W = 100 - L Now the area of the rectangle is A = WL Substitute the equation for W. A = (100 - L)L A = 100L -L^2 Let's make an initial guess of 40 ft and add an error component of e. So we'll use the length of (40+e) and see what we get. A = 100L -L^2 A = 100(40+e) - (40+e)^2 A = 4000 + 100e - (1600 + 80e + e^2) A = 4000 + 100e - 1600 - 80e - e^2 A = 2400 + 20e - e^2 Now looking at those 2 "e" terms is interesting. It's pretty obvious that any negative value of e will cause those term to result in a value less than 0, and decrease the available area. Also any value of e greater than 20 will also cause those 2 values to sum to a negative value and decrease the area. But a value of e in the range of 0 to 20 will result in a positive value and cause the area enclosed to be larger. So it's obvious that 40 feet isn't optimal. Let's pick the middle of the e values that result in something positive (0+20)/2 = 10 and add that to our initial guess, getting a length of 50 and replace length by (50+e) and see what happens. A = 100L -L^2 A = 100(50+e) -(50+e)^2 A = 5000+100e -(2500+100e + e^2) A = 5000+100e - 2500 - 100e - e^2 A = 2500 - e^2 This looks quite promising. Any non-zero value of e will result in the area enclosed being smaller. So the idea value of e is 0. That means that the idea length of the rectangle is 50 feet. And that makes the width 50 feet as well. Mind, this problem could have been also solved using the first derivative of the equation A = 100L -L^2, which would have been A' = 100 - 2L, and then solving for 0. But I did this problem to demonstrate that you don't need to resort to calculus for every maximum type of problem.

Answer:

The coordinates of the point P is 14.

Step-by-step explanation:

Let point A is at 8 and B is at 16.

P is the point where the line segment in the ratio 3 : 1.

This is also where P is [tex]\frac{3}{4}[/tex] rds the distance from A to B

The total distance is |16 - 8| = 8  

The distance between point AB is 8 units.

[tex]\frac{3}{4}[/tex] of 8 is 6.

So, the point P is 6 units from A .

8 + 6 = 14

P is at 14

Hence, the coordinates of the point P is 14.

This also works if you go 1/3 from B.

-8 is 4 from -4 which is 1/3 of 12.

Answer:

1) A person would need approximately 51 years to eat 855 pounds of apples.

2) A person would need approximately 69 years to eat 1120 pounds of turkey.

3) 6 people in the United States will eat 1260 quarts in next 5 years.

4) The statement is a nonsense.

Step-by-step explanation:

1) According to the German page Statista, a person in the United States had a per capita consumption of 16.91 pounds of fresh apples in 2018/19. If we consider that a person consume at same rate, then the time taken is obtained by dividing total amount of fresh apples by per capita consumption rate:

[tex]x = \frac{855\,pd}{16.91\,\frac{pd}{yr} }[/tex]

[tex]x = 50.562\,years[/tex]

A person would need approximately 51 years to eat 855 pounds of apples.

2) According to the German page Statista, a person in the United States had a per capita consumption of 16.40 pounds of turkey in 2018/19. If we consider that a person consume at same rate, then the time taken is obtained by dividing total amount of turkey by per capita consumption rate:

[tex]x = \frac{1120\,pd}{16.40\,\frac{pd}{yr} }[/tex]

[tex]x = 68.293\,years[/tex]

A person would need approximately 69 years to eat 1120 pounds of turkey.

3) Accoring to the US page Aghires, a person in the United States had a per capita consumption of 42 quarts of pop corn in 2017/2018. The total consumption of the groups equals the product of number of people, time and per capita consumption. That is:

[tex]x = 42\,\frac{qt}{yr}\times 6 \times 5\,yr[/tex]

[tex]x = 1260\,quarts[/tex]

6 people in the United States will eat 1260 quarts in next 5 years.

4) According to the US newspaper The South Florida Reporter, a person in the United States had a per capita consumption of 53 pounds of bread in 2017/2018. Consumption during 80 years can be estimated by knowing the product of time and per capita consumption. That is:

[tex]x = 80\,yr \times 53\,\frac{pd}{yr}[/tex]

[tex]x = 4240\,pd[/tex]

Which is only equivalent to about 10 % of the alleged indicator and, consequently, the statement is a nonsense.

Answer:

The answer is below

Step-by-step explanation:

The height of tank = 12 m = 1200 cm, the diameter of the tank = 8 meters, hence the radius of the tank = 8/2 = 4 m = 400 cm

Let h represent the water level = 8 m = 800 cm. The radius (r) of the water level at a height of 8 m is:

r/h = radius of tank/ height of tank

r/h = 400/1200

r = h/3

[tex]\frac{change\ in\ volume}{change\ in \ time}=water\ in-water\ out\\ \\\frac{dV}{dt=} water\ in-water\ out\\\\V=\frac{1}{3}\pi r^2h\\ \\r=\frac{1}{3}h \\\\V=\frac{1}{3}\pi (\frac{1}{3}h )^2h\\\\V=\frac{1}{9} \pi h^3\\\\\frac{dV}{dt} =\frac{1}{3} \pi h^2\frac{dh}{dt}\\\\\frac{dh}{dt}=2\ cm/min,h=8\ m=800\ cm\\\\[/tex]

[tex]\frac{dV}{dt} =\frac{1}{3} \pi (800)^2(2)=426666.7\ cm^3/min\\\\\frac{dV}{dt=} water\ in-water\ out\\\\426666.7\ cm^3/min= water\ in-water\ out\\\\426666.7\ cm^3/min= water\ in-20000\ cm/min\\ \\water\ in=426666.7\ cm^3/min+20000\ cm/min\\\\water\ in=446666.7 \ cm^3/min[/tex]

Answer:

[tex]95 \frac{3}{4} \: inch \leqslant x \leqslant 96 \frac{1}{4} \: inch[/tex]

Step-by-step explanation:

Given that a lumber supplier sells 96 inch Pieces of oak which must be within 1/4 of an inch.

This situation can be represented by the following absolute value inequality:

[tex]|x \: - 96| \: \leqslant \: \frac{1}{4} [/tex].

The absolute value can be thought of as the size of something because length cannot be negative. The length must be no more than 1/4 away from 96.

To simplify this, pretend this is a standard equality, |x-96| = 1/4. 1/4 is the range of acceptable length, 96 is the median of the range, and x is the size of the wood.

First apply the rule |x| = y → x = [tex]\pm[/tex]y

|x-96| = 1/4

x - 96 = [tex]\pm[/tex]1/4

x = [tex]96 \pm 1/4[/tex]

(These are just the minimum, and maximum sizes)

Now with a less than or equal to, the solutions are now everything included between these two values.

Therefore:

[tex]96 - 1/4 \: \leqslant x [/tex] [tex]\leqslant \: 96 + 1/4 [/tex]

With less than inequalities, you must have the lower value on the left, and the higher value on the right.

If x represents the size of the pieces, then the acceptable lengths are represented by this following inequality:

[tex]95 \frac{3}{4} \: inch \leqslant x \leqslant 96 \frac{1}{4} \: inch[/tex]

This is interpreted as x (being the size of the oak) is greater than or equal to 95 3/4, and less than or equal to 96 1/4 in inches.

Answer:

Answer:

[tex]S = (2,5)[/tex]

Step-by-step explanation:

Given

[tex]T = (0,3)[/tex]

[tex]Midpoint (M) =(1,4)[/tex]

Required

Determine the other end point (S)

Midpoint is calculated as thus:

[tex]M(x,y) = (\frac{S_x + T_x}{2},\frac{S_y + T_y}{2})[/tex]

This gives:

[tex](1,4) = (\frac{S_x + 0}{2},\frac{S_y + 3}{2})[/tex]

[tex](1,4) = (\frac{S_x}{2},\frac{S_y + 3}{2})[/tex]

Multiply through by 2

[tex]2 * (1,4) = (\frac{S_x}{2},\frac{S_y + 3}{2}) * 2[/tex]

[tex](2,8) = (S_x,S_y + 3)[/tex]

By comparison:

[tex]S_x = 2[/tex]

[tex]S_y + 3 = 8[/tex]

[tex]S_y = 8 - 3[/tex]

[tex]S_y = 5[/tex]

Hence:

The coordinates of S is

[tex]S = (2,5)[/tex]
