Answer:

True

Step-by-step explanation:

Meters, centimeters, inches, miles, etc. are units of length.

Answer:

Step-by-step explanation:

To find slope you have to take y2-y1 over x2-x1

y2=your second y poiny

y1=first y point

x2=second x point

x1=first x point

Since it is minus a negative you get to change it to a plus sign, because they cancel each other out.

3 + 7  

____

-4-0

10/-4

This isn't quite simplified, so you find a common factor for the numerator (top number) and the denominator (bottom number). You should note the number has to go into both numbers, not just one. The largest common factor would be 2 in this case.

10/2=5

-4/2=-2  

Now your simplified answer would be 5/2  

The slope of the line will be "[tex]-\frac{5}{2}[/tex]".

The given points are:

The slope (m) will be:

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

By substituting the given values, we get

= [tex]\frac{3-(-7)}{-4-0}[/tex]

= [tex]\frac{3+7}{-4}[/tex]

= [tex]-\frac{10}{4}[/tex]

= [tex]-\frac{5}{2}[/tex]

Thus the above slope is right.

Answer:

Step-by-step explanation:

hello :

here is an solution :

The probability that a student chosen at random plays football or cricket or both is approximately 0.8667, or 86.67%, after considering the number of students playing each sport and accounting for those who play both.

To calculate the probability that a student chosen at random plays football or cricket or both, we can use the concept of probability along with a Venn diagram to organize our information.

First, we need to calculate the total number of students that play at least one of the sports. We know that 8 students play both football and cricket, 14 students play football, and 20 students play cricket. However, the 8 students that play both sports are included in the totals for both football and cricket. Therefore, to find the number of students who play at least one sport, we need to subtract the students counted twice because they play both sports:

Total playing football or cricket or both = (Number playing football) + (Number playing cricket) - (Number playing both)
= 14 + 20 - 8
= 26 students

We also know there are 4 students who do not play football or cricket. To find the total number of students, we add the number of students who play either sport to those who play neither:

Total number of students = 26 (playing sports) + 4 (not playing any sports)
= 30 students

The probability that a student chosen at random plays football or cricket or both is calculated by dividing the number of students who play either sport by the total number of students:

P(playing football or cricket or both) = Number of students playing sports / Total number of students
= 26 / 30
= 0.8667 (rounded to four decimal places)

The probability is approximately 0.8667, or 86.67%.

The equation is [tex]2\frac{1}{8} - \frac{1}{2}[/tex] .

1/2 is equivalent to 4/8, and 2 1/8 is equal to 17/8. (two full sets of 8 + 1 = 8 + 8 + 1, or 17)

The new equation is [tex]\frac{17}{8} -\frac{4}{8}[/tex] . Subtract the numerators.

17 - 4 = 13 or 13/8

The improper fraction [tex]\frac{13}{8}[/tex] simplifies to [tex]1\frac{5}{8}[/tex] .

[tex]1\frac{5}{8}[/tex]

Answer

206.02

Step-by-step explanation:

r=d/2

=16.2/2=8.1

3.12*8.1*8.1=206.0154

to the nearest hundred=206.02

The area of the circle with a diameter of 16.2 inches is approximately 206.24 square inches.

The area of a circle can be found using the formula A = πr^2, where π represents the mathematical constant pi and r is the radius of the circle. Since the diameter of the circle is given as 16.2 inches, we can find the radius by dividing the diameter by 2: r = 16.2 / 2 = 8.1 inches. Now we can plug in this value into the formula to find the area: A = 3.14 * (8.1)^2 = 206.2446 square inches. Rounding this to the nearest hundredth, the area of the circle is approximately 206.24 square inches.

The correct answers are 4A+B, 1.5B, 12A

Step-by-step explanation:

The area of the whole figure is 4A+B cm²

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

The space enclosed by the boundary of a plane figure is called its area.

The area of a figure is the number of unit squares that cover the surface of a closed figure.

Given that, a figure having the area of one of the small right triangles outlined in blue is A cm² while the area of the square outlined in red is B cm²

The total area = the sum of the area of the 4 triangles and the square,

= A + A + A + A + B = 4A + b

Hence, the area of the whole figure is 4A+B cm²

Explanation:

The figure attached shows sketches the situation described.

You have two right triangles.

For the right triangle with the plane on the position A, you can write:

         ⇒ H = (800 + x) tan(20º)

For the right triangle with the plane on the position B, you can write:

        ⇒ H = x tan(21.4º)

To solve, equal both equations:

Substitute in the equation H = x tan(21.4º)

Answer: 8 First class tickets

Step-by-step explanation:

You can set up a system of equations for this problem. Let x = number of coach tickets and y = number of first class tickets. Then:

330x + 1220y = 12730    (cost of coach tickets plus cost of first class tickets is total budget)

x + y = 17    (number of coach tickets plus number of first class tickets is total number of people)

Solve the second equation for y to get y = 17 - x, then plug that into the first equation and solve for x:

330x + 1220(17 - x) = 12730

330x + 20740 - 1220x = 12730

-890x + 20740 = 12730

-890x = -8010

x = 9

Sarah bought x = 9 coach tickets. Plug that into the second equation and solve for y:

9 + y = 17

y = 8

Sarah bought y = 8 first class tickets.

Given Information:  

Number of lithium batteries = n = 16

Mean life of lithium batteries = μ = 645 hours

Standard deviation of lithium batteries = σ = 31 hours

Confidence level = 95%  

Required Information:  

Confidence Interval = ?

Answer:  

[tex]CI = 628.5 \: to \: 661.5 \: hours[/tex]

Step-by-step explanation:  

The confidence interval is given by

[tex]CI = \mu \pm t_{\alpha/2} (\frac{\sigma}{\sqrt{n}})[/tex]

Where μ is the mean life of lithium batteries, σ is the standard deviation, n is number of lithium batteries selected, and t is the critical value from the t-table with significance level of

tα/2 = (1 - 0.95) = 0.05/2 = 0.025

and the degree of freedom is

DoF = n - 1 = 16 - 1 = 15

The critical value (tα/2) at 15 DoF is equal to 2.131 (from the t-table)

[tex]CI = 645 \pm 2.131(\frac{31}{\sqrt{16}})[/tex]

[tex]CI = 645 \pm 2.131(7.75})[/tex]

[tex]CI = 645 \pm 16.515[/tex]

[tex]CI = 645 - 16.515 \: and \: 645 + 16.515[/tex]

[tex]CI = 628.5 \: to \: 661.5 \: hours[/tex]

Therefore, the 95% confidence interval is 628.5 to 661.5 hours

What does it mean?

It means that we are 95% confident that the mean life of 16 lithium batteries is within the interval of (628.5 to 661.5 hours)

Explanation:

Each circle has a radius of 'a'. So r = a.

The area of each circle is pi*r^2 = pi*a^2

The area of each square with side length b is b^2

The two stacks have the same volume only when the circle area is equal to the square area, so whenever pi*a^2 = b^2 is true.

Solving for b leads to b = sqrt(pi*a^2) = sqrt(pi)*a

The stacks must also be the same height for the volumes to be the same, so m = n as well.

Step-by-step explanation:

Final answer:

To find the length of the hypotenuse in a right triangle with legs of 7 ft and 10 ft, we use the Pythagorean theorem, resulting in a hypotenuse of approximately 12.21 feet.

Explanation:

The student is asking about the length of the hypotenuse in a right triangle where one leg is 7 ft and the other is 10 ft. To find the hypotenuse, we use the Pythagorean theorem which states a² + b² = c², where a and b are the lengths of the legs of the triangle, and c is the length of the hypotenuse.

For this triangle, the calculations would be:

a² = 7² = 49

b² = 10² = 100

a² + b² = c²

49 + 100 = c²

149 = c²

c = [tex]\sqrt{149[/tex]

c = 12.21 ft (rounded to two decimal places)

Therefore, the length of the hypotenuse of the triangle is approximately 12.21 feet.
