Stephen is testing the difference in means between time it takes to travel school in a bus and time it takes to travel to school in a car. Stephen hypothesizes that it takes more time to travel in a bus. He calculates a p-value of 2%. He concludes at a 1% significance level that the true mean is greater for a bus than a car.
Where did Stephen go wrong in his conclusion? Explain in detail.
Answer:
Kindly check explanation
Step-by-step explanation:
To test for Difference in mean times
Null hypothesis, H0 will be, there is no difference in mean times ; m1 = m2
Alternative hypothesis, there is difference in mean times ; m1 ≠ m2
Decision region :
When p value < α ; reject the Null
Here. ;
Pvalue = 2% = 0.02
α = 1% = 0.01
Pvalue > α
0.02 > 0.01
Since, Pvalue > α ; we do not reject the Null ;
Hence, conclusion should be, there is no difference in mean times of bus and car

In right ABC angle c is the right angle, AC = 7, and BC = 24. Find the value of the sine of the largest acute angle of the triangle.
Answer:
Step-by-step explanation:
Remark
AC and BC are the legs of a triangle. You are told that the right angle is at C. Both these sides have one endpoint C. That means that they are the shorter of the three lines. The first thing we must do is find the Hypotenuse. You need the Hypotenuse to get the sin of one or both of the acute angles.
Hypotenuse
a^2 + b^2 = c^2
a = 7
b = 24
c = ?
c^2 = 7^2 + 24^2
c^2 = 49 + 576
c^2 = 625
sqrt(c^2) = sqrt(625)
c = 25
Find the Largest Angle
The largest angle is going to be opposite the longest leg (not the Hypotenuse although you use the hypotenuse).
Sin(A) = 24/ 25
Sin(A) = 0.96
A = Sin-1(0.96)
A = 73.74

What is the equation of the line in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = 6x
Explaination:
slope intercept form is just y=mx+b, and since the slope is 6, you plug 6 into m, and then the y-intercept is 0, so you can drop it out of the equation

find the measure of angle 1
Answer:
44°
Step-by-step explanation:
8x - 4 = 6x + 8 (This is because they are corresponding angles)
8x - 6x = 8 + 4
2x = 12
x = 12 ÷ 2
x = 6
6x + 8 = angle 1 (Vertically opposite angles are equal)
Substitute the value of x in the equation '6x +8' to get the size of the angle.
6 × 6 + 8
36 + 8 = 44°
Angle 1 = 44°

Answer:
m = 1/3
Step-by-step explanation:
Step 1. Pick a line of the table to use as (x1, y1).
Step 2. Pick a different line of the table to use as (x2, y2).
Step 3. Use the slope formula:
m = (y2 -y1)/(x2 -x1)
Step 4. Simplify the result.
__
Here are these steps for this problem.
1, 2. use (x1, y1) = (-9, -5) and (x2, y2) = (-3, -3)
3. m = (-3 -(-5))/(-3 -(-9)) = 2/6
4. m = 1/3

There is a parallelogram ABCD with diagonals AC and BD. The diagonals AC and BD intersects each other at point E. Side AB is congruent to side CD. If ∠BAC ≅ ∠DCA, the Choose... theorem can be used to show that △ABE ≅ △CDE.
Answer:
SAS theorem
Step-by-step explanation:
Given
[tex]\square ABCD[/tex]
[tex]\[ \lvert \[ \lvert AB =\[ \lvert \[ \lvert CD[/tex]
[tex]\angle BAC = \angle DCA[/tex]
Required
Which theorem shows △ABE ≅ △CDE.
From the question, we understand that:
AC and BD intersects at E.
This implies that:
[tex]\[ \lvert \[ \lvert AE = \[ \lvert \[ \lvert EC[/tex]
and
[tex]\[ \lvert \[ \lvert BE = \[ \lvert \[ \lvert ED[/tex]
So, the congruent sides and angles of △ABE and △CDE are:
[tex]\[ \lvert \[ \lvert AB =\[ \lvert \[ \lvert CD[/tex] ---- S
[tex]\angle BAC = \angle DCA[/tex] ---- A
[tex]\[ \lvert \[ \lvert BE = \[ \lvert \[ \lvert ED[/tex] or [tex]\[ \lvert \[ \lvert AE = \[ \lvert \[ \lvert EC[/tex] --- S
Hence, the theorem that compares both triangles is the SAS theorem

On a certain hot summer's day, 540 people used the public swimming pool. The daily prices are $1.25 for children and $2.00 for adults. The receipts for admission totaled $822.75. How many children and how many adults swam at the public pool that day?
Answer:
There were 343 children and 197 adults.
Step-by-step explanation:
In order to solve this problem, you can use an equation after identifying the important information, like that there were 540 people, the cost for a child is $1.25, the cost for an adult is $2.00, and admission fees totaled $822.75:
where c = number of children, and a = number of adults,
c + a = 540
1.25c + 2a = 822.75
Now, you need to solve this system of equations by isolating one of the variables. I'll isolate c by multiplying the first equation by 2 since it's easier:
2c + 2a = 1080
- 1.25c + 2a = 822.75
= .75c = 257.25
Now, you can multiply both sides by 4/3 to find c:
c = 257.25 × 4 ÷ 3
c = 343
So there were 343 children. Now you can find the number of adults by substituting 343 for c in the first equation:
where c + a = 540 and c = 343,
343 + a = 540
a = 197
So, there were 197 adults.
HELP ME PLEASE 10 points!!!!!
tamika has $55 in her savings account. She plans on depostiting $5 per week into her account. Write and solve an inqequality to find out how many weeks she must save to have more than $100 in her account. Then interpet the solution
Answer:
x>9
Step-by-step explanation:
Tamika already has $55, which will stay the same independent of how much time passes. Since she deposits $5 per week, we can assign weeks a variable x. The amount of money in her account after x weeks is equal to 55+5x. If she must save over $100, we can create an inequality to solve for how many weeks must pass: 55+5x>100.
The question also asks to solve the inequality:
55+5x>1005x>100-55 (Subtract 55 from each side)5x>45x>9 (Divide each side by 5)This solution tells us that Tamika must save for more than nine weeks to have more than $100 in her account.

Find FD(round to the nearest tenth) please and thank you!
Answer:
FD = 25.9
Step-by-step explanation:
13x - 16 = 4x + 11
9x = 27
x = 3
using Pythagorean theorem:
FD² = 12² + [4(3) + 11]²
FD² = 144 + 23² = 144 + 529 = 673
FD = 25.94
