The Boston Celtics have won 16 NBA championships over approximately 50 years. Thus is may seemreasonable to to assume that in a given year the Celtics win the title with probability p = 16=50 = 0:32,independent of any other year. Given such a model, what would be the probability of the Celtics winningeight straight championships
Answer:
0.0001 = 0.01% probability of the Celtics winning eight straight championships.
Step-by-step explanation:
For each year, there are only two possible outcomes. Either the Celtics are the champions, or they are not. Each year is independent of other years. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
What would be the probability of the Celtics winning eight straight championships?
Each year, we have that [tex]p = 0.32[/tex]
Eight straight championships: [tex]P(X = 8)[/tex] when n = 8. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 8) = C_{8,8}.(0.32)^{8}.(0.68)^{0} = 0.0001[/tex]
0.0001 = 0.01% probability of the Celtics winning eight straight championships.

A 6-foot roll of butcher paper costs $1.44. What is the price per inch?
The price per inch of butcher paper is $0.02.
What is a word problem?"A word problem is a verbal description of a problem situation wherein one or more questions are posed, the answers to which can be obtained by the application of mathematical operations to information (usually numerical data) available in the text".
For the given situations,
A 6-foot roll of butcher paper costs = $1.44. Then
1-foot roll of butcher paper costs = [tex]\frac{1.44}{6}[/tex]
⇒ [tex]\$0.24[/tex]
1 foot = 12 inches
⇒ 12 inches roll of butcher paper costs = $0.24
Therefore, 1-inch roll of butcher paper costs = [tex]\frac{0.24}{12}[/tex]
⇒ [tex]\$0.02[/tex]
Hence we can conclude that the price per inch of butcher paper is $0.02.

mr dela cruz uses 18 yards of cloth for making 5 pants how many pants will he make for 72 yards of cloth
Answer:
18÷5= 3.6
3.6 = 4 yards
72 yards of cloth ÷ 4 yards of cloth = 18 pants
Step-by-step explanation:
3.6 yards rounded to the nearest is 4. So it takes 4 yards of cloth to make 1 pants. Since it takes 4 yards of cloth to make 1 pants, we simply divide 4 yards into 72 yards which equals to 18 pants.

Estimate the average rate of change from X = 2 to x = 5.
Answer:
Average rate of change = [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
We have to calculate the average rate of change of the graph at x = 2 to x = 5.
From the graph attached,
At x = 2,
f(2) = 3
At x = 5,
f(5) = 7
Since, average rate of change of the function between x = a and x = b is defined by,
Average rate of change = [tex]\frac{f(b) - f(a)}{b - a}[/tex]
Therefore, average rate of change of the function represented by the graph will be = [tex]\frac{7-3}{5-2}[/tex]
= [tex]\frac{4}{3}[/tex]

Sam can ride his bike 4.2 kilometers in 6 minutes. Amanda can ride her bike 3.2 kilometers in 8 minutes. Jesse can ride his bike 3.0 kilometers in 5 minutes.
Which rider might go farther in 1 minute?
Answer:
jesse or sam i think its sam by a little bit.
Step-by-step explanation:
Answer:
Sam
Step-by-step explanation:
Find all of their speeds to find how far they will go in 1 minute, by dividing the number of kilometers by the number of minutes:
Sam
4.2/6
= 0.7 km/min
Amanda
3.2/8
= 0.4 km/min
Jesse
3/5
= 0.6 km/min
Since 0.7 is the greatest number, that means Sam is the rider that will go the farthest in one minute.
use the distributive property to rewrite each expression (2+g)8
Answer:
16+8g
Step-by-step explanation:
Just multiple everything by 8
Hope this helps (:
Answer:
8g+16
Step-by-step explanation:
I guess it can be kind of confusing when the number outside of the parentheses is on the right side of the equation? I don't know lol, but the same rules apply.
If it helps, rewrite it as: (2+g)8 --> 8(2+g)
Now multiply: (8*2)+(8*g)
Simplify: 16+8g or 8g+16 (however you want to write it)

Prove that 17^16+17^14 is divisible by 5
We'll use the exponent rule that a^(b+c) = a^b*a^c
to break up 17^16 into 17^(14+2) = 17^14*17^2
That allows us to factor like so
17^16+17^14
17^14*17^2+17^14*1
17^14(17^2 + 1)
Computing 17^14 is a lot more difficult compared to computing 17^2 + 1, assuming you only could use paper and pencil.
Note that 17^2 = 17*17 = 289, so 17^2 + 1 = 289+1 = 290
Because 290 ends in a 0, this means that 5 is a factor
290 = 5*58
This makes 5 to be a factor of the original expression.
----------------
So overall,
17^16+17^14 = 17^14(17^2 + 1) = 17^14*290 = 17^14*5*58 = 5*17^14*58
The stuff "17^14*58" doesn't matter. All we care about is that factor of 5.
Since 5 is a factor, this means that 17^16+17^14 is a multiple of 5, or 17^16+17^14 is divisible by 5.
Phrased another way, 17^16+17^14 all divided over 5 leads to some integer. In this case, the integer would be the result of 17^14*58.

[tex]21.79 + c \leq 25[/tex]
Joshua can spend up to 3.21 on a card.
Step-by-step explanation:
[tex]21.79 + c \leq 25[/tex] is the correct equation because Joshua is spending 21.79 on flowers, a certain amount on the card, and the maximum he can spend is 25. That is why you use the less than or equal to sign.
To solve, first subtract 21.79 from both sides to get: [tex]c \leq 3.21[/tex]. This means that Joshua can spend up to 3.21 on a card.

Josh has 4 boxes of candy to share with his 20 classmates. If each classmate receives the same amount of candy, how much candy should each classmate get? Your answer
Answer:
1/5 of a box of candy
Step-by-step explanation:
Because John has 4 boxes of candy, he needs to divide this by his 20 classmates. So we have 4/20, which reduces to 1/5. So each classmate would get 1/5 of a box of candy (assuming that Josh himself does not get any candy).
