Tevin leaves school to walk home. His friend, Karen, notices 0.2 hours later that Tevin forgot his phone at the school. So Karen rides her bike to catch up to Tevin and give him the phone. If Tevin walks at 2 mph and Karen rides her bike at 8.2 mph, find how long (in hours) she will have to ride her bike until she catches up to him.
Answers
Answer:
Step-by-step explanation:
equation is:
8.2x=0.2x+0.4
if x is time
8.2x-0.2x=0.4
8x=0.4
x=0.05 hours from when Karen starts and 0.45 hours fromt the time tevin started.

Answer:
x = 12.05
using sine rule:
[tex]\boxed{sin(a) = \frac{opposite}{hypotenuse} }[/tex]
Here given the angle is 35° and hypotenuse is 21.
To find x:
→ sin(35) = [tex]\frac{x}{21}[/tex]
→ x = 21 * sin(35)
→ x = 12.04510516
→ x = 12.05 ................rounded to nearest tenth.

Simplify -3(9+2z).Simplify this expression and I will give you virtual points.
Answers
Answer:
-27 -6z
Step-by-step explanation:
"Simplify" in this context means "eliminate parentheses." You do that by making use of the distributive property. The factor -3 outside the parentheses multiplies each term inside parentheses.
-3(9 +2z)
= -3(9) +(-3)(2z)
= -27 -6z
Hey there!
-3(9 + 2z)
= -3(9) - 3(2z)
= -27 - 6z
= -6z - 27
Therefore, your answer is: -6z - 27

Answer:
y ≥ - 0.8
Step-by-step explanation:
[tex]\sqrt{25y^2 +40y+16}[/tex] = 5y + 4
[tex]\sqrt{(5y+4)^2}[/tex] = 5y + 4
5y + 4 = 5y + 4 and 5y + 4 ≥ 0 ⇒ y ≥ - 0.8
y ∈ [ - 0.8 , ∞ )
- ( 5y + 4 ) = 5y + 4
10y = - 8
y = - 0.8
The answer is y ≥ - 0.8

z = 23
Step-by-step explanation:
ÀC = z + 7
30 = z + 7
30 - 7 = z
z = 23
2x - 3 = 5x - 21
21 - 3 = 5x -2x

Education researchers are interested in the workload expectations of freshmen at a local university. Which of the
following techniques would give a stratified random sample?
Randomly select 10 freshmen from each of the majors at the university
Randomly select 10 freshmen from the cafeteria on each of the 5 days of the first school week.
Randomly select 1 professor at the university and have them survey all of their freshman students.
Survey the students in some randomly selected freshman seminar classes, since freshmen are randomly put into
those classes
Answers
Answer:
A: Randomly select 10 freshmen from each of the majors at the university.
Step-by-step explanation:
This is because stratified random sampling is taking a population and dividing them into subpopulations. So, majors would be the best way to divide up college freshmen into different subsections to survey them about their workloads because each major would have a different answer and result.
The techniques to give a stratified random sample would be A: Randomly select 10 freshmen from each of the majors at the university.
What is simple random sampling?If the sampling is done from the population randomly, without any other rule, then such sampling is called simple random sampling. Items are selected in a fixed size, all randomly.
The best sampling is simple random sampling, as it is randomly picking data values from the population.
Stratified random sampling it is taking a population and dividing them into subpopulations.
The majors would be the best way to divide up college freshmen into different subsections to survey them about their workloads because each major would have a different result.

First, let's find the area of the rectangle.We know that the area of a rectangle is the length times width, or 20⋅32in this example:20⋅32=640So the area of the rectangle is 640ft2.You may not know the area of a semicircle, but that's fine −we know the area of a circle, or πr2.Since the area of a semicircle is half the area of a circle, we just do the area of the circle divided by 2:So the area of a semicircle is πr22.The question asks for πto just be 3.14, so instead the equation is A=3.14r22The picture gives the diameter of the circle.To find the radius, or r, we divide the diameter by 2:202=10Now we can solve for the area of the semicircle:3.14(10)223.14(100)23142157ft2Now that we now the areas of the rectangle and semicircle, we can add them up to find the area of the rose garden:640+157=797ft2

b. If the number of samples were doubled, by what factor would the confidence interval change

Answers
We have that the population standard deviation and confidence interval is mathematically given as
SD=1
W = 2.8284
Standard deviation and the new widtha) Generally, normal distribution 95% of the values lies within 2 standard deviations from the mean.
Therefore, we have here:
2*2SD = 51 - 47
2*2SD
SD=1
Hence, the standard deviation is
SD=1
b)
Where,the margin of error is inversely proportional to the square root of sample size.
1 / sqrt{2}
Hence, the new width is
