Explanation:
When x = 0, we have y = 18. The y intercept value is 18. This is the initial value, and it's the value of 'a' in the equation below
y = a*b^x
The value of b is tied to the growth or decay rate, depending on if b > 1 or if 0 < b < 1 respectively.
In this case, we have growth due to y increasing as x increases. They increase together.
When x increases by 1 like this, the value of b can be determined by dividing any y term over its previous value. So for instance, we can say b = 21.6/18 = 1.2 or we could say b = 25.92/21.6 = 1.2
Then note how 1.2 = 6/5, which means b = 6/5
Therefore, y = a*b^x becomes y = 18(6/5)^x
--------------
We can confirm this equation by plugging in x values from the table and we should get the y values, or f(x) values, listed
Example: plug in x = 0 to find that
y = 18(6/5)^x
y = 18(6/5)^0
y = 18(1)
y = 18 which matches
Then try x = 1
y = 18(6/5)^x
y = 18(6/5)^1
y = 18(1.2)
y = 21.6 that also matches
I'll let you confirm the other x values.

In a class of students, the following data table summarizes how many students play
an instrument or a sport. What is the probability that a student chosen randomly
from the class plays a sport or an instrument?
Answer:
19/28
Step-by-step explanation:
People who count: 4 + 2 + 13 = 19
Total amount of pplz: 19 + 9 = 28
Answer:
15/28
Step-by-step explanation:
The total amount of students in the class is 28. This will be useful for later.
From this table, we can see that 2 people play sports alone and 13 play an instrument alone. Since it says the number of students that play a sport or an instrument, this means that the top left box is not counted. This leaves you with an answer of 15/28.
A sprinter ran the 400 meter dash in 44.62 seconds. Convert her speed into miles per hour
Answer:
v = 20.7 mph
Step-by-step explanation:
Given that,
Distance, d = 400 m
Time, t = 44.62 s =
We need to find the speed of the sprinter. The speed of an object is defined as total distance covered divided by time taken. It can be given by :
[tex]v=\dfrac{d}{t}\\\\=\dfrac{0.248\ mile}{0.012\ s}\ (As\ 1\ m=0.000621371\ mile)\\\\=20.7\ mph[/tex]
Hence, the speed of the sprinter is equal to 20.7 mph.

it takes electricians 36 days to wire a new housing subdivision. how many days would 32 electricians take to do the same job?
Answer:
The 32 electricians will take 1 day and 3 hours to complete the wiring.
Step-by-step explanation:
Since it takes electricians 36 days to wire a new housing subdivision, to determine how many days would 32 electricians take to do the same job the following calculation must be performed:
36/32 = X
1.125 = X
1 = 24
0.125 = X
0.125 x 24 = X
3 = X
Therefore, the 32 electricians will take 1 day and 3 hours to complete the wiring.

A basketball player has a 0.654 probability of making a free throw. If the player shoots 13 free throws, what is the probability that she makes less than 6 of them?
Insert the correct symbol to represent this probability.
Provide your answer below:
P(X
5)
Using the binomial distribution, it is found that there is a 0.0432 = 4.32% probability that she makes less than 6 of them.
-----------------------
For each throw, there are only two possible outcomes. Either she makes it, or she misses it. The probability of making a throw is independent of any other throw, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
x is the number of successes. n is the number of trials.p is the probability of a success on a single trial.The probability of making less than 6 is:
[tex]P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{13,0}.(0.654)^{0}.(0.346)^{13} \approx 0[/tex]
[tex]P(X = 1) = C_{13,1}.(0.654)^{1}.(0.346)^{12} \approx 0[/tex]
[tex]P(X = 2) = C_{13,2}.(0.654)^{2}.(0.346)^{11} = 0.0003[/tex]
[tex]P(X = 3) = C_{13,3}.(0.654)^{3}.(0.346)^{10} = 0.0020[/tex]
[tex]P(X = 4) = C_{13,4}.(0.654)^{4}.(0.346)^{9} = 0.0093[/tex]
[tex]P(X = 5) = C_{13,5}.(0.654)^{5}.(0.346)^{8} = 0.0316[/tex]
Then
[tex]P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0 + 0 + 0.0003 + 0.0020 + 0.0093 + 0.0316 = 0.0432[/tex]
0.0432 = 4.32% probability that she makes less than 6 of them.

Solve 2Q + 5s=r for s and show ALL your steps.
Answer:
2q-r= 5s
divide both sides by 5
2q-r/s =5s/5
therefore S= 2q-r/s
Answer:
Step-by-step explanation:
Subtract 2Q from both sides
2Q + 5s − 2Q = r − 2Q
Simplify
5s = r − 2Q
Divide both sides by 5

The highest speed ever recorded for a bicycle was 166.944 miles per hour. What is this speed rounded to the NEAREST tenth?
Answer:
166.9 miles per hour
Step-by-step explanation:
To round a number to the nearest tenth, look at the next place value to the right (the hundredths). If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right. Then, the answer is 166.9.
