A box contains 7 yellow, 5 blue, and 4 red balls. Three balls are drawn at random. Find the probability that:
a)
All three balls are the same color
c)
Two balls are yellow and one is blue
d)
All three balls are different colors
Answer:
a) 7/80 = 0.0875
b) 3/16 = 0.1875
c) 1/4 = 0.2500
Step-by-step explanation:
There are a total of 16 balls. 3 are selected. There are ₁₆C₃ possible combinations.
a) If all 3 balls are the same color, they are either all yellow OR all blue OR all red.
The number of ways of choosing 3 yellow balls from 7 is ₇C₃.
The number of ways of choosing 3 blue balls from 5 is ₅C₃.
The number of ways of choosing 3 red balls from 4 is ₄C₃.
The total probability is:
P = (₇C₃ + ₅C₃ + ₄C₃) / ₁₆C₃
P = (35 + 10 + 4) / 560
P = 49 / 560
P = 7 / 80
P = 0.0875
b) The number of ways of choosing 2 yellow balls from 7 is ₇C₂.
The number of ways of choosing 1 blue ball from 5 is ₅C₁.
The probability of both is:
P = ₇C₂ ₅C₁ / ₁₆C₃
P = 21 × 5 / 560
P = 105 / 560
P = 3 / 16
P = 0.1875
c) If all 3 balls are different colors, then there is exactly 1 yellow, 1 blue, and 1 red.
The number of ways of choosing 1 yellow ball from 7 is ₇C₁.
The number of ways of choosing 1 blue ball from 5 is ₅C₁.
The number of ways of choosing 1 red ball from 4 is ₄C₁.
The probability of all events is:
P = ₇C₁ ₅C₁ ₄C₁ / ₁₆C₃
P = 7 × 5 × 4 / 560
P = 140 / 560
P = 1 / 4
P = 0.2500

Answer:
108
Step-by-step explanation:
So the area of the rectangle is easy.
12 * 5 = 60
Now you have to do the triangles.
The height is (13 - 5) / 2 = 4
The bases are 12
The area of one is (12 * 4) / 2
The area of both is 12 * 4 = 48
60 + 48 = 108

Answer:
Step-by-step explanation:
Number of students 10
Problem 1. $625 for the bus hire per friday, So 625*4=$2500
Problem 2. 2500/25=$100 each for the whole 4 weeks
Problem 3.
10 students tickets 220= 2200 for all tickets. The bus, 625/10 = $62.5*4= $250 dollars for the whole 4 weeks for the bus so in all each student pays $470 each
20 students, tickets 220=4400 for all tickets. The bus, 625/20=$31.25*4=$125 for the whole 4 weeks for the bus, so in all each student must pay $345 each
30 students, tickets 220 = 6600 for all tickets. The bus, 625/30 =$20.83*4=$83.32 for the whole 4 weeks for the bus, so in all each student must pay $303.32 each
41 students, tickets $160=$6560 for all tickets. The bus, because you need 2 buses at 625 each so $1250 for both buses 1250/41= 30.49*4=$121.96 for the whole 4 weeks for the bus. So in al each student must pay $281.96 each

A diver dives from the board at a local swimming pool. Her height, y, in metres, above the water in terms of her horizontal distance, x, in metres, from the end of the board is given by y= -x^2 + 2x + 3. What is the diver's maximum height?
Answer:
4 meters
Step-by-step explanation:
Given a quadratic equation in which the coefficient of [tex]x^2[/tex] is negative, the parabola opens up and has a maximum point. This maximum point occurs at the line of symmetry.
Since the divers height, y is modeled by the equation
[tex]y= -x^2 + 2x + 3[/tex]
Step 1: Determine the equation of symmetry
In the equation above, a=-1, b=2, c=3
Equation of symmetry, [tex]x=-\dfrac{b}{2a}[/tex]
[tex]x=-\dfrac{2}{2*-1}\\x=1[/tex]
Step 2: Find the value of y at the point of symmetry
That is, we substitute x obtained above into the y and solve.
[tex]y(1)= -1^2 + 2(1) + 3=-1+2+3=4m[/tex]
The maximum height of the diver is therefore 4 meters.

The probability of reference book and then, without replacing it, picks up a nonfiction book is 5/136.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
Nadia's bookshelf contains 10 fiction books, two reference books, and five nonfiction books.
So, the probability of getting reference book
= 2/ 17
and, the probability of getting nonfiction book
= 5/ 17
Now, the probability of reference book and then, without replacing it, picks up a nonfiction book
= 2/ 17 x 5 / 16
= 10 / 272
= 5 /136

the button on ernestos shirt has a diameter of 8 millimeters.what is the buttons radius
Answer:
4 mm
Step-by-step explanation:
The radius is half the diameter, so in this case the radius of each button is 4 mm.
Answer:
The radius would be 4 millimetres
Step-by-step explanation:
The radius is the length from one side to the centre of the circle.
The diameter is the length from one side to another.
To work out the radius you would simply divide the diameter of 8 by 2, this gives you 4 millimetres. This is because the radius is half of the diameter.
1) Divide 8 by 2.

2. Write a quadratic function with zeros at 6 and -2.
Answer:
f(x) = x^2 - 4x - 12
Step-by-step explanation:
If 6 is a zero, (x - 6) is a factor. Likewise, if -2 is a zero, (x + 2) is a factor.
Multiplying these two factors together, we get:
f(x) = x^2 - 4x - 12

Express x^2-5x+8 in the form (x-a)^2+b
Answer:
x^2 - 5x + 8 = (x - 5/2)^2 + 7/4
Step-by-step explanation:
(x - a)^2 + b = x^2 - 2ax + a^2 + b
equate to your quadratic :
x^2 - 5x + 8 = x^2 - 2ax + (a^2 + b)
equating coefficients (ignoring x^2 as the coefficient is 1 for both)
for x :
-5 = -2a --> a = 5/2
for x^(0) : 8 = a^2 + b , note a = 5/2
thus,
8 = (5/2)^2 + b
8 = 25/4 + b
b = 8 - 25/4 = 32/4 - 25/4 = (32 - 25)/4 = 7/4
hence a = 5/2 , b = 7/4
thus,
x^2 - 5x + 8 = (x - 5/2)^2 + 7/4
