probability ( p ) = 0.4
number of games played ( n ) = 5
Find the Probability of winning at least 2 games
P( wining ) = 0.4.
P ( losing ) ( q ) = 1 - 0.4 = 0.6
x = 2 , 3 , 4 , 5
P ( at least 2 out of 5 ) = p( k=2) + p(k=3) + p(k=4) + p(k5 )
= 0.3456 + 0.2304 + 0.0768 + 0.01024
= 0.66304 ( using binomial distribution calculator )

Kyle is making a frame for a rectangular piece of art. The length of the frame is 3 times the width, as shown below. A rectangle with a length of 3 x and height of x. If Kyle uses 18 feet of wood to make the frame, what is the length of the frame? 6.75 4.50 2.25 9.00
Answers
Explanation:
Let the width be x
Length = 3x
Perimeter of frame = 18
2(l + w) = 18
2(3x + x) = 18
2(4x) = 18
8x = 18
x = 18/8
x = 2.25 feet

m<RQP = 33degrees
Step-by-step explanation:
From the given diagram, m<P = 90degrees
Equating this to 5x+15
5x+15 = 90
5x = 90 - 15
5x = 75
x = 75/5
x = 15
m<RQP = 2x+3
m<RQP = 2(15) + 3
m<RQP = 30 + 3
m<RQP = 33degrees

Kai cuts out all the page numbers of a b\ook. He takes each number and cuts the numbers into separate digits (single digit numbers are already separate). Given that the book has 999 pages numbered 1 through 999, how many separate digits does Kai have when he is finished
Answers
Answer:
2,889 digits
Step-by-step explanation:
Total pages of the book = 999 pages
Page 1 - 9 cut separately = 9 digits
Page 10 - 99 = 90 pages
Total digits = 2(90)
= 180 digits cut separately
Page 100 - 999 = 900 pages
Total digits = 3(900)
= 2,700 digits cut separately
how many separate digits does Kai have when he is finished
Total separate digits Kai have when he is finished = 9 digits + 180 digits + 2700 digits
= 2,889 digits
Total separate digits Kai have when he is finished = 2,889 digits

a 10 foot ladder is leaning against a wall if the ladder reaches 8 feet up the wall how far is the base of the ladder from the wall.
Answers
Answer:
6ft
Step-by-step explanation:
This requires a little use of the Pythagorean Theorem.
The length of the leaning ladder is the hypothenuse of the right triangle formed by the wall and the ladder.
Hyp. = 10 ft Say this is C
The ladder height up the wall = 8 ft. Say this A.
We need to find the other leg, say B ,of the right triangle.
C^2 = A^2 + B^2
10^2 = 8^2 + B^2
100 = 64 + B^2 => B^2 = 100 - 64 = 36
B^2 = 36 so, B = 6 The positive square root since length is positive.
B = 6 ft This is how far the ladder bottom is from the wall.
Double Check: 10^2 = 8^2 + 6^2 or 100 = 64 + 36 Ok. As, it should. This check could be done mentally.
In addition, this is a Pythagorean Triple. (6, 8, 10).
Answer: 6 ft.

Big brutus pizza had two deals on pizza the first was $6 for a cheese pizza plus $3 for each topping the second deal was $20 per cheese pizza and 1 dollar per topping wat is the x and y
Answers
Answer:
[tex]x = 7[/tex] --- toppings
[tex]y = 27[/tex] ---- amount
Step-by-step explanation:
Given
[tex]y \to\ amount[/tex]
[tex]x \to\ topping[/tex]
The first deal is:
[tex]y = 6 + 3x[/tex]
The second is:
[tex]y = 20 + x[/tex]
Required
The value of x and y [for which both deals are equal]
We have:
[tex]y = 6 + 3x[/tex]
[tex]y = 20 + x[/tex]
Equate both
[tex]y=y[/tex]
So, we have:
[tex]6 + 3x = 20 + x[/tex]
Collect like terms
[tex]3x - x = 20 - 6[/tex]
[tex]2x =14[/tex]
Divide by 2
[tex]x = 7[/tex]
Substitute [tex]x = 7[/tex] in [tex]y = 20 + x[/tex]
[tex]y = 20 + 7[/tex]
[tex]y = 27[/tex]

Answer:
B
Step-by-step explanation:
Remember SOHCAHTOA:
SOH = Sine is Opposite over Hypotenuse
CAH = Cosine is Adjacent over Hypotenuse
TOA = Tangent is Opposite over Adjacent
The Tan of A would be [tex]\frac{10.9}{5}[/tex]
The Tan of B would be [tex]\frac{5}{10.9}[/tex]
Therefore, B is correct.
The answer is B
Step-by-step explanation:
Tan = the abbreviation toa which means in a right angled triangle the opposite side over the adjacent side is equals to the tan of the angle.
Therefore, tan B =opposite side angle B over adjacent side angle B.
tan B=5/10.9
the price p of an aluminum tube is jointly proportional to its radius r and the length l. if a 12-foot pipe with 5-inch radius costs 5250 pesos, how much will be the cost of a 9-foot pipe with a 6-inch radius?
Answers
Answer:
4725 pesos
Step-by-step explanation:
The price p of an aluminum tube is jointly proportional to its radius r and the length l.
For joint variation, we have the expression:
p ∝rl
Hence
p = krl
Step 1
Solving for k
if a 12-foot pipe with 5-inch radius costs 5250 pesos,
5250 = k × 12 × 5
5250 = 60k
k = 5250/60
k = 87.5
Step 2
how much will be the cost of a 9-foot pipe with a 6-inch radius
We make use of the expression:
p = krl
p = 87.5 × 9 × 6
p = 4725 pesos
Therefore, the cost is = 4725 pesos
