The set A is the set of sports balls that are spherical, the complement of set A is {baseball}.
Given that the universe set U = {baseball, basketball, football, tennis ball, soccer ball, volleyball}.
What is set?Sets in mathematics, are simply a collection of distinct objects forming a group. A set can have any group of items, be it a collection of numbers, days of a week, types of vehicles, and so on. Every item in the set is called an element of the set.
The set A is the set of sports balls that are spherical
Set A={basketball, football, tennis ball, soccer ball, volleyball}
So, the complement of Set A is {baseball}
Because, a baseball infield is in the shape of a square, with each base at a vertex.
Hence, the set A is the set of sports balls that are spherical, the complement of set A is {baseball}.

Grogg typed the following $1000$ expressions into his calculator, one by one: \[\sqrt{1}, \sqrt{2}, \sqrt{3}, \sqrt{4}, \dots, \sqrt{999}, \sqrt{1000}. \]how many times will grogg's result be an integer?
Since 30² = 900 and 40² = 1600, between 30 and 40 of the numbers Grogg enters will reduce to integers. Now just find which count is correct. We don't have to look far:
31² = 961
32² = 1024
so there 31 of the outputs of √1, √2, √3, ..., √1000 are integers.
Grogg will result to integers with 31 outputs from √1, √2, √3, ..., √1000 .
What are integers?An integer serves as the whole number which can be a positive or negative numbers , such as 6, 9, but it cannot be a fraction.
since, she is starting from √1, √2, √3, up to √1000 , then we know that
31² = 961, then we can find the correct count which is 31. so if she is to input those number into square root one after the other , she will have 31 count.
Therefore, Grogg will result to integers with 31 outputs from √1, √2, √3, ..., √1000 .

Using the hypergeometric distribution, it is found that there is a 0.1538 = 15.38% probability that the top three finishers in the contest will all be seniors.
What is the hypergeometric distribution formula?The formula is:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.N is the size of the population.n is the size of the sample.k is the total number of desired outcomes.In this problem:
There are 14 players in total, hence N = 14.Eight are seniors, hence k = 8.Three will be taken from the sample, hence n = 3.The probability that all of them are seniors is P(X = 3), hence:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 3) = h(3,14,3,8) = \frac{C_{8,3}C_{6,0}}{C_{14,3}} = 0.1538[/tex]

Please help with math questions.
the heights of a group of
people are normally distributed
with a mean of 62 inches and a
standard deviation of 1.5. what
percent of the group is between
62 and 65 inches tall?
The percentage of the group that is between 62 and 65 inches tall is 47.725%
How to determine the probability?The given parameters are:
Mean, μ = 62Standard deviation, σ = 1.5Calculate the z-scores for x = 62 and x = 65 using:
z = (x - μ)/σ
So, we have:
z = (62 - 62)/1.5 = 0
z = (65 - 62)/1.5 = 2
The percentage is then represented as:
P(62 < x < 65) = P(0 < z < 2)
Rewrite as:
P(62 < x < 65) = P(z < 2) - P(z < 0)
Evaluate
P(62 < x < 65) = 0.47725
Express as percentage
P(62 < x < 65) = 47.725%
Hence, the percentage of the group that is between 62 and 65 inches tall is 47.725%

There were 27 children in a class.
There were twice as many boys as girls.
How many boys were there?
A 21 boys B 18 boys C 16 boys D 14 boys E 9 boys
Answer:
b 18 boys
Step-by-step explanation:
In order to solve this problem we must create a system of equations.
Creating a system of equations
Let x = number of boys and y = # of girls
We are given that in total there are 27 children which means # of boys + # of girls = 27 so we can say x + y = 27
We are also given that there are twice as many boys as girls so we can also say x = 2y ( as # of boys = twice the number of girls )
Solving the system
Now to find the # of boys and girls we must solve the system. To do so we are going to use the substitution method.
What is the substitution method?
The substitution method is where one of your variables ( x in this case ) is defined by an expression in which you can plug in or " substitute " it into the other equation ( we can substitute x = 2y into the other equation and solve for y )
Substitute equation 2 into equation 1
Equation 1 : x + y = 27
==> plug in x = 2y
y + 2y = 27
==> combine like terms
3y = 27
==> divide both sides by 3
y = 9
So there are 9 girls in the classroom
Solving for # of boys
To solve for the number of girls we plug in the # of girls (y=9) into one of the equations and solve for x
equation : x + y = 27
==> plug in y = 9
x + 9 = 27
==> subtract 9 from both sides
x = 18
There are 18 boys in the classroom
Checking our work:
Now that we have found the possible answers we can check our work. To do so we are going to want to plug in the values of x and y into both equations and if both are true our answer is correct
Equation 1 x + y = 27
==> plug in x = 18 and y = 9
18 + 9 = 27
==> simplify
27 = 27 ✓
equation 2 x = 2y
==> plug in x = 18 and y = 9
18 = 2(9)
==> multiply 2 and 9
18 = 18 ✓
Both are correct therefore we can conclude that there are 18 boys and 9 girls.
A represents Mr. Mole's altitude relative to the ground (in meters) after t
minutes.
A=-2.3t-7A=−2.3t−7A, equals, minus, 2, point, 3, t, minus, 7
How fast did Mr. Mole descend
Using the slope of the linear function, it is found that Mr. Mole descends 2.3 meters per minute.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, Mr. Mole's altitude in meters after t minutes is given by:
A = -2.3t - 7.
The rate of change is the slope of m = -2.3, hence, Mr. Mole descends 2.3 meters per minute.

Step-by-step explanation:
Given m n, find the value of x and y.
Answer:
X= 38°
Y = 142°
Step-by-step explanation:
let the angle vertically opposite to 142° = w
therefore, w= 142° ( vertically opposite angles are equal)
hence,x+ w =180° ( two interior angles sum up to 180°)
x+ 142° = 180°
x= 180 - 142 = 48°
X = 38°
then calculating for Y
X + Y = 180° ( angles on a straight line sum up to 180°)
38+Y = 180
Y = 180- 38
Y = 142°
