Malik's average pace was 5.5 minutes per mile.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Given; Malik uses an app on his phone to track how far he rides his bike. Yesterday, he biked a new trail in a total of 57.5 minutes, including a 2.5-minute water break. The app notified Malik that he rode 10 miles.
Now, This equation represents the situation.
Now, solve the equation for p;
10p+2.5 = 57.5
Subtract 2.5 from both sides;
10p = 55
Divide both sides by 10
p = 5.5
Therefore, Malik's average pace was 5.5 minutes per mile.

4) Shreya's school is selling tickets to a fall musical. On the first day of ticket sales the school sold
13 adult tickets and 9 student tickets for a total of $138. The school took in $163 on the second
day by selling 3 adult tickets and 14 student tickets. Find the price of an adult ticket and the
price of a student ticket. Find the price of and adult ticket and the price of a student ticket?
Answer:
adult: $3student: $11Step-by-step explanation:
Let x and y represent the prices of adult and student tickets, respectively. Then the revenue equations are ...
13x +9y = 138
3x +14y = 163
Solving this using a graphing calculator, we find (x, y) = (3, 11).
The price of an adult ticket is $3; the price of a student ticket is $11.
_____
Algebraic solution
When the numbers are "messy," as they are here, I like to use the "cross-multiplication method" for solution. I find it easier to use the order 1, x, y, rather than the order x, y, 1 as shown in the second attachment. That way, the coefficients are in their original order, with the first coefficient repeated. Note the right-side constant must be subtracted to get the form ax+by+c = 0.
[tex]\begin{array}{cccc}13&9&-138&13\\3&14&-163&3\end{array}[/tex]
Then we have ...
1/(13·14 -3·9) = x/(9·(-163) -14·(-138)) = y/((-138)·3 -(-163)·13)
x = 465/155 = 3 . . . . price of an adult ticket
y = 1705/155 = 11 . . . price of a student ticket

receive a coupon for their next visit. Each customer has a 10% probability of being selected to receive a

selected.
Suppose that 2 customers pay for their meals, one after the other.
What is the probability that NEITHER customer is selected to receive a coupon?

Using the binomial distribution, it is found that there is a 0.81 = 81% probability that NEITHER customer is selected to receive a coupon.
For each customer, there are only two possible outcomes, either they receive the coupon, or they do not. The probability of a customer receiving the coupon is independent of any other customer, which means that the binomial 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]
The parameters are:
x is the number of successes. n is the number of trials. p is the probability of a success on a single trial.In this problem:
For each customer, 10% probability of receiving a coupon, thus [tex]p = 0.1[/tex].2 customers are selected, thus [tex]n = 2[/tex]The probability that neither receives a coupon is P(X = 0), thus:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{2,0}.(0.1)^{0}.(0.9)^{2} = 0.81[/tex]
0.81 = 81% probability that NEITHER customer is selected to receive a coupon.

Contestants A, B, C, and D are in a 10K race. How many different ways can a race with 4 runners be completed? (Assume there is no tie.) In how many ways can A finish first and C finish second? What is the probability that A finishes first and C finishes second? Enter a reduced fraction or decimal.
Using the arrangements formula and the probability concept, it is found that:
The race can be completed in 24 ways.A can finish first and C second in 2 ways.[tex]\frac{1}{12}[/tex] probability that A finishes first and C finishes second.The number of possible arrangements of n elements is given by:
[tex]A_n = n![/tex]
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem, there are 4 runners, hence, the number of different ways the race can be completed is:
[tex]A_4 = 4! = 24[/tex]
Considering A first and C second, for the third and fourth positions, it is an arrangement of 2 elements, hence:
[tex]A_2 = 2! = 2[/tex]
The probability is:
[tex]p = \frac{2}{24} = \frac{1}{12}[/tex]
[tex]\frac{1}{12}[/tex] probability that A finishes first and C finishes second.

The angle above is supplementary to the angle (2x - 2), therefore

At the height of 2467.2 meters from the earths surface, the air pressure equals 50% of the air pressure at the surface of the Earth.
What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is that air pressure may be represented as a function of height (in meters) above the surface of the Earth, as shown below -
P(h) = P[tex]e^{-0.000122h}[/tex]
where {P} is the air pressure at the surface of the Earth, and his the height above the surface of the Earth, measured in meters.
For 50% of the air pressure at the surface of the Earth, we can write -
50P/100 = P[tex]e^{-0.000122h}[/tex]
1P/2 = P[tex]e^{-0.000122h}[/tex]
1/2 = [tex]e^{-0.000122h}[/tex]
- 0.000122h = log(1/2) = - 0.301
h = - 0.301/- 0.000122
h = 2467.2 meters
Therefore, at the height of 2467.2 meters from the earths surface, the air pressure equals 50% of the air pressure at the surface of the Earth.

To find the average price of all 4 pies, we have to know the price of all 4 pies. You have only given the price of 3 of the pies, so there is no way to figure the average. The best you can do in this case is say that the peach pie costs (6 + 7 + 11 + X) / 4 dollars, where X is the cost of the peach pie.
I think you meant to say that the peach pie cost the average of the prices of the other three pies. In which case, it costs (6 + 11 + 7) / 3, or $8.00.
