The length of a rectangle is
4 meters less than 2 times the width. The perimeter is 22 meters. Find the width.
Answer:
5 meters
Step-by-step explanation:
We should derive an equation to solve this problem.
Let's assign x to width and y to length.
[tex]2x-4=y[/tex]
and
[tex]2x+2y=22[/tex]
so
[tex]2x+2(2x-4)=22[/tex]
[tex]2x+4x-8=22[/tex]
[tex]6x-8=22[/tex]
[tex]6x=30[/tex]
[tex]x=5[/tex]
Width = 5 meters

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?
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.

A function f (x) is graphed on the coordinate plane.
What is the function rule in slope-intercept form?
Answer:
y= 2x + 1
Step-by-step explanation:
Given the point (0,1) and (1,3)
You can use the slope formula to get the slope.
y2-y1/x2-x1
3-1/1-0 = 2/1 = 2
Slope = 2
Now rewrite into point-slope formula
y-3=2(x-1)
Distribute
y-3= 2x -2
Add 3 to both sides
y= 2x + 1

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
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.

the empirical probability of getting a head?
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.

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

Part C

Part D

Part E

need help on algebra ii question
Answer:
≈ 6 seconds
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.
