You flip a coin 10 times and you get 10 heads. Based on these 10 outcomes what is
the empirical probability of getting a head?
Answers
The empirical probability is the ratio of the number of times an event occurred to the total number of trials. Hence, the empirical probability is 1.
The empirical probability is defined thus :
Number of times event occurred / total number of outcomesHence, the empirical probability of head in the experiment :
Number of heads / total number of tossesP(Head) = 10/10 = 1
Therefore, the empirical probability of getting a head is 1.

Which ordered pairs is a solution to −5x + 3y > 12?
(3, 9)
(-5, 5)
(3, -6)
(-2, -5)
(2, 8)
(-6, 0)
Answers
Answer :-
Given inequality ,
-5x +3y > 12 3y > 5x + 12 y > 5/3x + 12/3y > 5/3x + 4From the options ,
When x is 3 and y = 9
y >1* 5 + 4y > 5 +4 9> 9 ( Not possible )When x is -5 y is 5
y > 5/3*-5 + 4y > -8.3 + 4 5 > -3.7 ( Possible )When x is 3 y is -6
y > 5 + 4 -6 > 9 ( Not possible )When x is -2 y is -5
y > -3.33 + 4 -5 > -0.67 ( Possible )When x is 2 y is 8
y > 3.33 + 4 8 > 7.77 ( possible )When x is -6 y is 0
y > -10 +4 0 > -6 ( possible )We’ll substitute the given points to determine which is a solution that satisfies the inequality:
(3, 9):
-5(3) + 3(9) > 12
-15 + 27 > 12
12 > 12 (False statement, as 12 ≯ 12)
(-5, 5):
-5x + 3y > 12
-5(-5) + 3(5) > 12
25 + 15 > 12
40 > 12 (True statement). Thus, it is a solution.
(3, -6)
-5(3) + 3(-6) > 12
-15 - 18 > 12
-33 > 12 (False statement. -33 ≯ 12).
(-2, -5)
-5(-2) + 3(-5) > 12
10 - 15 > 12
-5 > 12 (False statement. -5 ≯ 12).
Therefore, the only solution is (-5, 5).

Answer:

Step-by-step explanation:
When it says about hitting the ground, it means it hits the t-axis.
That means we have to solve for t-intercepts to find the solution.
Finding t-intercept, let y = 0.
[tex] \displaystyle \large{0 = - 16 {t}^{2} + 96t + 3}[/tex]
Use the Quadratic Formula.
[tex] \displaystyle \large{t = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac } }{2a} }[/tex]
Substitute in a = -16, b = 96 and c = 3.
[tex] \displaystyle \large{t = \frac{ - 96 \pm \sqrt{ {96}^{2} - 4( - 16)(3)} }{2( - 16)} } \\ \displaystyle \large{t = \frac{ - 96 \pm \sqrt{ 9216 + 192} }{ - 32} } \\ \displaystyle \large{t = \frac{ - 96 \pm \sqrt{ 9408} }{ - 32} } \\ \displaystyle \large{t = \frac{ - 96 \pm 56 \sqrt{3} }{ - 32} } \\ [/tex]
Then simplify to simplest form.
[tex] \displaystyle \large{t = \frac{ - 96 \pm 56 \sqrt{3} }{ - 32} } \\ \displaystyle \large{t = \frac{ 12\pm 7\sqrt{3} }{ 4} } \\ [/tex]
Then use the highest value/root which is 12+7√3 over 4 then input it in a calculator and you will see that the highest root is close to 6.
We use the highest root because thats when y or height = 0 hence if height = 0 then the object finally hits the ground.

What is a function?A relation is a function if it has only One y-value for each x-value.
The set of all possible values which qualify as inputs to a function is known as the domain of the function, or it can also be defined as the entire set of values possible for independent variables.
The set of all the outputs of a function is known as the range of the function or after substituting the domain, the entire set of all values possible as outcomes of the dependent variable.
The codomain is the set of all possible values which can come out as a result but the range is the set of values which actually comes out.

Unit Rates
Kiley and her parents traveled to visit her grandmother. They drove 24.3 miles from their house to the airport in hour. At the airport, they exited the car and walked for hour to the waiting area by the gate to board their plane. Their walk covered 1.2 miles. From the waiting area, they walked another 0.1 mile to board the plane. The plane left the gate 45 minutes after they arrived at the waiting area. The plane flew 346 miles in hours. After the plane landed, Kiley and her parents walked for 30 minutes, covering 1.1 miles, before they found a cab. It was a 15-minute cab ride to get to Kiley’s grandmother’s house, which was 12.3 miles away.
Answer the following questions about Kiley’s trip. All questions are written in terms of an average rate. Assume that an average rate includes the time that Kiley is at rest (that is, not moving).
In this task, you will write the ratio of miles to hours for each leg of Kiley’s trip. You will then, express the ratio as a decimal number. Next, you will find the unit rate in miles per hour (mph) for each leg of the trip. If your unit rate includes a repeating decimal number, you must indicate which digits repeat (for example, write when the 3 repeats.) A description of each leg is listed below in parts A through F.
Part A
the car ride from Kiley’s house to the airport
Part B
at the airport, the walk from the car to the waiting area by the gate
Part C

A certain town is clustered around the town's largest employer, a paper mill. A researcher notices a large number of children with asthma and suspects the proportion of children with asthma in this town may be larger than the nationwide proportion of 7%.
(a) (2 pts) Write the null and alternative hypotheses.
(b) (3 pts) Suppose the researcher committed a Type I error. What did the researcher conclude and what was the reality regarding children with asthma?
(c) (3 pts) Suppose the researcher committed a Type II error instead. What did the researcher conclude and what was the reality regarding children with asthma?
Answers
Using statistical concepts, it is found that:
a)
The null hypothesis is: [tex]H_0: p \leq 0.07[/tex]
The alternative hypothesis is: [tex]H_0: p > 0.07[/tex]
b)
The type I error means that the researcher concluded that the proportion in this town was above 7%, while in reality it wasn't.
c)
The type II error means that the researcher concluded that the proportion in this town was not above 7%, while in reality it was.
Item a:
At the null hypothesis, we test if the proportion is the nationwide proportion of 7% of less, thus:
[tex]H_0: p \leq 0.07[/tex]
At the alternative hypothesis, we test if the proportion is larger than the nationwide proportion, that is:
[tex]H_1: p > 0.07[/tex]
Item b:
A Type I error happens when a true null hypothesis is rejected.
Thus, the type I error means that the researcher concluded that the proportion in this town was above 7%, while in reality it wasn't.
Item c:
A Type II error happens when a false null hypothesis is not-rejected.
Thus, the type II error means that the researcher concluded that the proportion in this town was not above 7%, while in reality it was.

Maria is training for a triathlon. Yesterday, she rode her bike for eight and two-thirds miles in two-thirds of an hour. If Maria continues to rides at the same rate, how far will she ride in one hour? help plzz
Answers
cross multiply
(2/3)(x) = (8 2/3)(1)
2/3x = 26/3
x = 26/3 * 3/2
x = 26/2...which equals 13....she will ride 13 miles in 1 hr
Maria's rate is 13 miles per hour. If she continues to ride at the same rate, she will ride 13 miles in one hour.
We have,
Maria's rate can be calculated by dividing the distance she rode by the time she took.
Rate = Distance / Time
Yesterday, she rode 8 and two-thirds miles in two-thirds of an hour:
Rate = (8 + 2/3) miles / (2/3) hour
First, let's convert the mixed number (8 + 2/3) to an improper fraction:
8 + 2/3 = (8 * 3 + 2) / 3 = 26/3
Now, plug in the values:
Rate = (26/3) miles / (2/3) hour
When you divide fractions, you can multiply the first fraction by the reciprocal of the second fraction:
Rate = (26/3) * (3/2) miles/hour
Rate = (26/2) miles/hour
Rate = 13 miles/hour
Thus,
Maria's rate is 13 miles per hour. If she continues to ride at the same rate, she will ride 13 miles in one hour.

Answers
We are given:
x (-4, 3)
y (2, -1.5)
z (4, -1)
A (3, 3)
And we are trying to find the hypotenuse of triangle YZA because that’s what the line from “point A to XZ” is.
The Pythagorean Theorem is a^2 + b^2 = c^2
We can use it to find the distance between any two points. If we imagine 2 more lines, one going straight down from the higher point, and the other one going horizontally from the lower point until it meets the vertical line. We have another triangle.
The length of the horizontal segment of a triangle is just the difference of. the x values. And the length of the vertical segment is just the difference of their y values.
So we have
(x2 - x1)^2 + (y2 - y1)^2 = c^2
Simplified:
sqrt((x2 - x1)^2 + (y2 - y1)^2) = c
Segment YZ =
sqrt((x2 - x1)^2 + (y2 - y1)^2) = c
sqrt((4 - 2)^2 + (-1 - -1.5)^2) = c
sqrt(4 + .25) = c
sqrt(4.25) = c
2.06155281281 = c
The length of YZ is 2.06155281281.
Now we need to know segment ZA.
Segment ZA =
sqrt((x2 - x1)^2 + (y2 - y1)^2) = c
sqrt((3 - 4)^2 + (3 - -1)^2) = c
sqrt(1 + 16) = c
sqrt(17) = c
4.12310562562 = c
The length of segment ZA is 4.12310562562.
Finally:
AZ^2 = YZ^2 + ZA^2
AZ^2 = (2.06155281281)^2 + (4.12310562562)^2
AZ^2 = 4.25 + 17
AZ^2 = 21.25
AZ = sqrt(21.25)
AZ = 4.60977222865
