Answer:
[tex]S = \{(Oatmeal, Coffee),(Eggs, Coffee),(Pancakes,Coffee),[/tex] [tex](Oatmeal, Tea),(Eggs, Tea),(Pancakes,Tea)\}[/tex]
Step-by-step explanation:
Given
[tex]Meal = \{Oatmeal, Eggs, Pancakes\}[/tex]
[tex]Beverage = \{Coffee, Tea\}[/tex]
Required
Determine the sample space
The sample space is a list of combination of 1 meal and 1 beverage.
Because one individual can order only one of the meals and one of the beverages at any one time, then no two orders can be the same
The sample space (S) is as follows:
[tex]S = \{(Oatmeal, Coffee),(Eggs, Coffee),(Pancakes,Coffee),[/tex] [tex](Oatmeal, Tea),(Eggs, Tea),(Pancakes,Tea)\}[/tex]

The local school board wants to get parents to evaluate teachers. They select 100 parents and find that 89% approve of their child’s teacher
Answer:
Ok? Did you finished asking the question? Just in case, that is 89/100 or 0.89
Step-by-step explanation:
Here, Population: All parents, Sample: 100 parents and Parameter: Parents’ approval of teachers
What is sample space in probability?The sample space of a random experiment is the collection of all possible outcomes. An event associated with a random experiment is a subset of the sample space. The probability of any outcome is a number between 0 and 1. The probabilities of all the outcomes add up to 1.
Given that, A local school board wants to get parents to evaluate teachers. They select 100 parents and find that 89% approve of their child’s teacher, here we need to find the population, sample and parameter of interest
So, as we see,
The population is the entire group that you want to draw conclusions about.
Therefore, the population here is = All parents
The sample is the specific group that you will collect data from.
Therefore, the sample = 100
The parameter is any characteristic that can help in defining or classifying a particular system.
Therefore, the parameter = Parents’ approval of teachers
Hence, we get Population: All parents, Sample: 100 parents and Parameter: Parents’ approval of teachers

Martin used 1/3 of his inheritance to pay off the mortgage on his house and 3/5 of what was left to purchase a new automobile. How much was left from his total $30,000 inheritance after these two expenditures
Answer:
12,000
Step-by-step explanation:
Since 1/3 of 30,000 is 10,000, we are left with 20,000. 3/5th of 20,000 is 12,000.

its given that x varies directly with y square and x=3 and y=3.Find the value of x when y=45
Step-by-step explanation:
x = ky², where k is a real constant.
When x = 3, y = 3.
=> 3 = 9k, k = 1/3.
Therefore x = y²/3.
When y = 45, x = 45²/3 = 675.

7. Slips are drawn form a box containing 100 slips written with numbers 1 to 100. If three slips are
drawn one after the another with replacement, then the probability that first slip bears an even
number, second bears an odd number, third bears a perfect square number, is
a)1/100
b)1/25
c)1/45
d)1/40
Answer:
D
Step-by-step explanation:
We need the numbers of each before we can calculate the probability
Number of even numbers are 50
Number of odd numbers are 50
Number of perfect squares;
1 , 4 , 9 , 16 , 25 , 36 , 49 , 64 , 81 and 100
10 perfect squares
Probability of selecting even = probability of selecting odd = 50/100 = 1/2
Probability of selecting a perfect square = 10/100 = 1/10
Thus, the probability of having the draws in the other stated in the question will be;
1/2 * 1/2 * 1/10 = 1/40

Step-by-step explanation:
180-95 = 85
85 plus 43 = 128
180 - 128 = 52
180-52 = 128
Answer:
y=128
Step-by-step explanation:
The exterior pleus interior angle makes a 180 degree
so 180-95=85
now the interior angles of a triangle add up to 180
so the in triangle
get 43+85+?=180
180-85-43=52
nowing this we need to find the exterior angle unlike the first we are given the interior not the exterior but same process goes
180-52=128
y=128

The coordinates of Y' will be: A'(4, -3)
Step-by-step explanation:
Triangle XYZ with vertices
X(-5, -2)Y(-3, 4)Z(-1, 1)We have to determine the answer for the image Y' of the point Y(-3, 4) with respect to the line mirror y=x.
We know that when P(x, y) is reflected in y = x, we get P'(y, x)
i.e.
The rule of y=x:
P(x, y) → P'(y, x)As we are given that Y(-3, 4), so the coordinates of Y' will be:
A(-3, 4) → A'(4, -3)
Therefore, the coordinates of Y' will be: A'(4, -3)
The two triangles shown have the same perimeters. What is the perimeter of each triangle
Answer:
28 units
Step-by-step explanation:
Since the perimeter of both triangles is same,
the sum of all sides of first triangle = sum of all sides of second triangle
or, 6x + 3 + 2x + 4x = 5x + 5x + 3x + 2
or, 12x + 4 = 13x + 2
or, 4-2 = 13x - 12x
or, 2 = x
Now,
Putting the value of x in the perimeter of first triangle,
12x + 4= 12* 2+ 4
= 28 units
How do I graph quadratics in vertex form?
Answer:
Step-by-step explanation:
Equation of the quadratic function given as,
g(x) = [tex]\frac{1}{3}(x-6)^2+1[/tex]
Since, leading coefficient of the function is positive,
Parabola will open upwards.
For x- intercepts,
g(x) = 0
[tex]\frac{1}{3}(x-6)^2+1=0[/tex]
(x - 6)² = -3
(x - 6) = ±√(-3)
x = 6 ± √(-3)
Since, x is an imaginary number, this function has no x-intercepts.
Similarly, for y-intercept,
x = 0
g(0) = [tex]\frac{1}{3}(0-6)^2+1[/tex]
= 12 + 1
= 13
y-intercept of the function → y = 13
Vertex of the parabola → (6, 1)
For x = 12,
g(12) = [tex]\frac{1}{3}(12-6)^2+1[/tex]
= 13
Therefore, one point lying on the graph will be (12, 13).
Now we can graph the quadratic function given in the question.

Answer:
10
Step-by-step explanation:
Using Euler's formula for polyhedra
F + V - E = 2
Here V = 16 and E = 24, thus
F + 16 - 24 = 2, that is

A recipe uses 5 cups of milk to make 10 servings. If the same amount of milk is used for each serving, how many servings can be made from three quarts?
Answer: 24 servings
Step-by-step explanation:
First and foremost, we should note that:
4 cups = 1 quart
Therefore, 3 quarts = 3 × 4 cups = 12 cups
Since she uses 5 cups of milk to make 10 servings, it means that 1 cup of milk is used to make 2 servings. Therefore, 12 cups would be used to make:
= 12 × 2
= 24 servings.

The line passes through points [tex](2,0)\,,\,(0,2)[/tex]
Let [tex](x_1,y_1)=(2,0)\,,\,(x_2,y_2)=(0,2)[/tex]
Equation of a line passing through points [tex](x_1,y_1)\,,\,(x_2,y_2)[/tex] is given by [tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-0=\frac{2-0}{0-2}(x-2)\\y=\frac{2}{-2}(x-2)\\y=-1(x-2)\\y=-x+2[/tex]

[tex]f(x)=y=-x+2[/tex]
Put [tex]x=-2[/tex]
[tex]f(-2)=-(-2)+2=2+2=4[/tex]
A bookstore bought a case of 10 books at a wholesale price of $84. The bookstore will sell the books at a 25 percent
markup, and each book will be sold for the same amount. How much will they sell each book in the case for?
O $8.40
O $10.50
O $105.00
O $105.80
Answer:
$ 8.40
Step-by-step explanation:
divide 84 by 10 and you will get $8.40.
To find how much they bought each book for, you must divide by 10. 74 divided by 10 is 7.4. Then if they are selling them for 20% more, then multiply 7.4 and 1.2
Your answer is $8.80

Answer:
A = 51° b = 15.3858... c = 24.448
Step-by-step explanation:
Given: B= 39°
a = 19
and that it's a right triangle
so that means the other 3rd angle is
A+39+90=180
A= 51°
use SOH CAH TOA to remember how sin cos and tan fit on the triangle
Sin(x)=Opp/Hyp Cos(x)=Adj/Hyp Tan(x)=Opp/Adj
Let's use Tan to find b
Tan(b) = Opp / Adj
Tan(39) = b / 19
19*Tan(39) = b
15.38589... = b
use Pythagoras to find c
c = [tex]\sqrt{a^{2} +b^{2} }[/tex]
c = [tex]\sqrt{19^{2} +15.3858^{2} }[/tex]
c = 24.448....
