Answer: Option A; 19
Step-by-step explanation:
The data is:
We have 40 students.
16 play football
9 play basketball
4 play bot sports.
We want to find the number of students that do not play either sport, for this we should add the number of students that play football and the number of students that play basketball, subtracting the number of students that play both sports (because we sill be counting those two times, this is because those 4 students are included in the 16 for football and also in the 9 for basketball.)
N = 16 + 9 - 4 = 12 + 9 = 21
the number of students that do not play basket or football is equal to:
40 - N = 40 - 21 = 19
The correct option is A
The numbers 4 through 14 are placed in a
bowel and drawn at random then replaced
after being drawn. What is the probability of
drawing the number 14 and then a number
less than 12?
The probability of drawing the number 14 is 1/10 (because there are 10 different numbers to pick from). The probability of drawing a number less than 12 is 8/10 (or 4/5 simplified). Multiply the fractions: 1/10 *4/5 = 4/50. Simplify to 2/25. The probability of drawing 14 and then a number less than 12 is 2/25.

Find the area of the rhombus.
Please help ASAP
Answer:
The area of rhombus = 195 yd²
Step-by-step explanation:
Points to remember
Area of rhombus = d₁d₂/2
Where d₁ and d₂ are the diagonals of the rhombus
To find the area of given rhombus
Here diagonals of rhombus are given
From the figure we get,
d₁ = 13 + 13 = 26 yd and
d₂ = 7.5 + 7.5 = 15 yd
Area = d₁d₂/2 = (26 * 15 )/2 = 13 * 15 = 195 yd²
Therefore the area of rhombus = 195 yd²

Answer:
p = 1/6
Step-by-step explanation:
5/6 - 1/3 n = p(5-2n)
Multiply each side by 6 so we do not have any fractions
6(5/6 - 1/3 n) = 6*p(5-2n)
5 - 2n = 6p (5-2n)
Divide each side by (5-2n) to isolate 6p
(5-2n)/(5-2n) = 6p (5-2n)/ (5-2n)
1 = 6p
Now divide by 6 to get p alone
1/6 = 6p/6
1/6 = p
Isaac is working as a security guard. He earns $8.45 an hour. He earns double time for any overtime over 40 hours. Last week he worked 44 hours. How much did he earn last week? (Hint: double time means 2 times the regular hourly rat.)
your answer would be $405.60
The answer is 709.8 You would do 8.45 times 40 = 338 now since he did overtime you multiply it by 2. 338*2= 676. He also did another 4 hours 8.45*4=33.8 now you add these together 33.8+676 = 709.8
Ty had 10 eggs. He made 4 servings of scrambled eggs. He used n eggs for each serving.
create an expression to represent the number of eggs Ty has left.
[tex]10-4n=x[/tex]
Hope this helps.
Brainliest would help me as well.
Final answer:
The number of eggs Ty has left after making 4 servings of scrambled eggs, using n eggs for each serving, is represented by the algebraic expression 10 - 4n.
Explanation:
To determine the number of eggs Ty has left after making scrambled eggs, we need to use a simple algebraic expression. If Ty started with 10 eggs and used n eggs for each of the 4 servings, we can represent the number of eggs used in total as 4n.
To find the number of eggs remaining, we subtract the total number of eggs used from the initial number of eggs:
Number of eggs remaining = Initial number of eggs - Number of eggs used
Number of eggs remaining = 10 - 4n

An ellipse has a vertex at (0, -7), a co-vertex at (4,0), and a center at the origin. Which is the equation of the ellipse in standard form?
ANSWER
[tex]\frac{ {y}^{2} }{49} + \frac{ {x}^{2} }{ 16 } = 1[/tex]
EXPLANATION
The given ellipse has a vertex at (0, -7), a co-vertex at (4,0), and a center at the origin.
The equation of an ellipse with vertex on the y-axis and center at the origin is given by
[tex]\frac{ {y}^{2} }{a ^{2} } + \frac{ {x}^{2} }{ {b}^{2} } = 1[/tex]
[tex]\frac{ {y}^{2} }{( - 7) ^{2} } + \frac{ {x}^{2} }{ {4}^{2} } = 1[/tex]
[tex]\frac{ {y}^{2} }{49} + \frac{ {x}^{2} }{ 16 } = 1[/tex]
The equation of the ellipse with a vertex at (0, -7), a co-vertex at (4,0), and a center at the origin is x^2/16 + y^2/49 = 1.
Explanation:To find the equation of the ellipse in standard form, we need to identify the lengths of the major and minor axes. The given vertex at (0, -7) indicates that the semi-major axis length, a, is 7 because the distance from the center to a vertex measures the semi-major axis. Similarly, the co-vertex at (4, 0) represents the semi-minor axis length, b, which is 4.
Since the center is at the origin (0, 0), the standard form of the ellipse equation is given by x^2/b^2 + y^2/a^2 = 1. Plugging the values of a and b, we get x^2/4^2 + y^2/7^2 = 1. So, the equation of the ellipse is x^2/16 + y^2/49 = 1.

Answer:
[tex]\left[\begin{array}{ccc}7\\4\\2\end{array}\right][/tex]
The answer is a single-column matrix (7,4,2)
Step-by-step explanation:
In such multiplication of matrices, you have to proceed by multiplying each ROW of the first matrix by the COLUMN of the second matrix. So,
[tex]\left[\begin{array}{ccc}3&6&1\end{array}\right] * \left[\begin{array}{ccc}2\\0\\1\end{array}\right] = (3 * 2) + (6 * 0) + (1 * 1) = 6 + 0 + 1 = 7[/tex]
then...
[tex]\left[\begin{array}{ccc}2&4&0\end{array}\right] * \left[\begin{array}{ccc}2\\0\\1\end{array}\right] = (2 * 2) + (4 * 0) + (0 * 1) = 4 + 0 + 0 = 4[/tex]
and
[tex]\left[\begin{array}{ccc}0&6&2\end{array}\right] * \left[\begin{array}{ccc}2\\0\\1\end{array}\right] = (0 * 2) + (6 * 0) + (2 * 1) = 0 + 0 + 2= 2[/tex]

The sum of the digits of a two digit number is 14. The difference between the tens digit and the units digit is 2. If x is the tens digit and y is the ones digit, which system of equations represents the word problem?
xy = 14 and x - y = 2
x + y = 14 and x - y = 2
x + y = 14 and y - x = 2
Answer:
B. x + y = 14 and x - y = 2
Step-by-step explanation:
Sum means addition, so the sum of the tens digit (x) and the ones digit (y) is equal to 14 (x + y = 14).
Difference means subtraction, so the difference between the tens digit (x) and the ones digit (y) is 2 (x - y = 2).
I hope this helps =)
Answer:
Option B. will be the answer.
Step-by-step explanation:
If the tens digit is x and ones digit is y, then the number formed will be xy.
Now we fill form the equations as per statements given in the question.
"The difference between tens and unit digits is 2"
x - y = 2 --------(1)
"Sum of the digits of two digit number is 14"
x + y = 14 -------(2)
Therefore, system of equations will be as the given equations 1 and 2.
Option B is the answer.

tents hold 2, 3, 5, 6, or 12 people. how many combinations of tents are possible to sleep 32 all tents are fully occupied and exactly one 12 person tent is used.
there would be 12 combinations
Answer:
12
Step-by-step explanation:
We are given that tent hold 2,3,5,6 or 12 people.
We have to find the combinations of tents are possible to sleep 32 all tents are fully occupied and exactly one 12 person tent is used.
If one 12 person tents is used then remaining people=32-12=20
Therefore, 20 people that must be in other tents.
To place 20 persons in combination of 2,3,5 and 6.
20=5+5+5+5
20=5+5+5+2+3
20=6+6+6+2
20=2(10)=2+2+....+2(10 times)
20=5+5+2(5)(5 times add 2)
20=6+6+2(4) (4 times add 2)
20=3+3+3+3+3+3+2
20=3+3+3+3+3+5
20=3+2+6+5+2+2
20=3+3+3+3+6+2
20=3+3+5+5+2+2
20=6+6+3+5
Hence, there are 12 possible combination of tents to sleep 32 all tents are fully occupied and exactly one 12 person tents is used.

Post A and Post B are 120 meters apart. Post B and Post C are 300 meters apart. Ben cycled from Post A to Post B in 15 seconds. Then he cycled from Post B to Post C in 55 seconds. Find Ben's average speed for the distance from post A to Post C.
Show work
Answer: 6 meters per second
Step-by-step explanation:
Ben's average speed from Post A to Post C is 6 meters per second, calculated by dividing the total distance cycled (420 meters) by the total time taken (70 seconds).
Explanation:The subject of the problem is calculating average speed. In this context, Ben's average speed can be calculated by dividing the total distance cycled by the total time taken.
Total distance is the sum of the distance from Post A to Post B and from Post B to Post C, which is 120 meters + 300 meters = 420 meters.
Total time is the sum of the time taken from Post A to Post B and from Post B to Post C, which is 15 seconds + 55 seconds = 70 seconds.
So, Ben's average speed=Total Distance/Total Time.
This equals 420 meters/70 seconds= 6 meters/second.
Therefore, Ben’s average speed for the entire distance from Post A to Post C is 6 meters per second.

Type the correct answer in each box. Use pi= 22/7, and round your answers to the nearest interger. The perimeter of the largest cross section of a sphere is 88 centimeters. The radius is 14 cm. The volume of the sphere is __ cm^3
Answer:
11,499 cm^3
Step-by-step explanation:
The volume of a sphere is given by the formula [tex]V=\frac{4}{3}\pi r^3[/tex]
The radius is given as 14, we plug it into the formula and find the volume:
[tex]V=\frac{4}{3}\pi r^3\\V=\frac{4}{3}(\frac{22}{7}) (14)^3\\V=11498.66[/tex]
rounded to nearest integer, the volume is 11,499
Answer:
r=14 cm
V=11499 cubic cm
Step-by-step explanation:
If the radius of the sphere is r cm, then the perimeter of the largest cross section is the circumference of the circle qith radius r. Thus,
[tex]88=2\pi r,\\ \\r=\dfrac{88}{2\pi}=\dfrac{44}{\pi}=\dfrac{44}{\frac{22}{7}}=\dfrac{44}{1}\cdot \dfrac{7}{22}=14\ cm.[/tex]
Thvolume of the sphere can be calculated using formula
[tex]V=\dfrac{4}{3}\pi r^3.[/tex]
Since r=14 cm, we get
[tex]V=\dfrac{4}{3}\cdot \dfrac{22}{7}\cdot 14^3=\dfrac{4\cdot 22\cdot 2\cdot 14^2}{3}=\dfrac{34496}{3}\approx 11499\ cm^3.[/tex]
Find the volume of the prism.
Answer:

where
B is the area of the base of the prism (triangular base in this problem)
L is the length of the prism (perpendicular distance between the top and the bottom)
Find the area of the triangular base B
[tex]B=\frac{1}{2}(3)(4)=6\ units^2[/tex] ---> area of a triangle
we have
[tex]L=20\ units[/tex]
substitute in the formula of volume
[tex]V=6(20)=120\ units^3[/tex]
