Answer:
Reject Null Hypothesis given that P-value < ∝
Step-by-step explanation:
Applying the Five ( 5 ) step model and assuming ∝ = 0.05
First step : determine the Null hypothesis
H0 : Age and support for Anti-smoking = independent
Second step : Determine the alternate hypothesis
Ha : Age and support for Anti-smoking ≠ independent
Thirdly : Identify significance level ( ∝ ) = 0.05
4th step : Calculate the Test statistic and P-value
Chi-squared test = 36.1429 using excel function
P-value = 1 - CHISQ.DIST(36.1429, 1, TRUE) < 0.0001
finally : we can conclude that Age and support for Anti -smoking are not Independent hence we Reject The Null hypothesis. Given that
P-value < ∝

Abdullah is kicking a soccer ball into the air. The path of the soccer ball can be modeled by a quadratic equation where the point (6, 12) represents the vertex and the x-axis represents the ground. Which equation could represent the location of the soccer ball when it hits the ground? A 0=−(x−6)2+12 B 0=−(x+6)2−12 C 0=−(x−6)(x−12) D 0=−(x+6)(x+12)
9514 1404 393
Answer:
A. 0 = −(x−6)^2+12
Step-by-step explanation:
The vertex form of a quadratic equation is ...
y = a(x -h)² +k . . . . . . for vertex (h, k) and scale factor 'a'
When the given vertex (h, k) = (6, 12) is used, we find the form of the equation to be ...
y = a(x -6)² +12
The ball will be on the ground when y = 0. Here, the vertical scale factor 'a' is -1, so the equation representing the ball being on the ground is ...
0 = -(x -6)² +12 . . . . . . matches choice A

Find an equation of the line passing through the pair of points. Write the equation in slope-intercept form.
(3,7), and (7.3)
y=0
Answer:
y=10-x
Step-by-step explanation:
1. Find the slope of the equation using the formula (change in y/change in x)
(3-7)/(7-3)=-4/4=-1
2. Plug in the slope and one of the coordinate points to the slope-intercept form to find the y-intercept.
slope-intercept form: y=mx+b
7=-3+b
b=10
3. Put the slope-intercept form of the equation together.
y=10-x

Solve the system by elimination.
-4x - 4y = 0
4x + 4y = 0
[tex]\begin{bmatrix}4x+4y=0\\ -4x-4y=0\end{bmatrix}[/tex]
Subtract 4y from both sides.
[tex]4x+4y-4y=0-4y[/tex]
Simplify
[tex]4x=-4y[/tex]
Divide each side by 4
[tex]\frac{4x}{4}=\frac{-4y}{4}[/tex]
Simplify

Substitute x as -y.

A chord is units from the center of a circle. The radius of the circle is units. What is the length of the chord?
Answer:PLZ MARK BRAINLIST
Draw a line from the center of the circle to the chord to form a right triangle.
The radius (20) forms the hypotenuse of the right triangle and distance from the center to the chord (16) forms a leg.
Use the Pythagorean Theorem to find the length of the other leg x (which would be 1/2 the length of the chord):
x^2 + 16^2 = 20^
x = 12
So the entire chord length = 12 * 2 = 24 units
write the slop intercept form of the equations below.
1. slope= 1/4,y intercept = 4
2. y-5=-4(x+1)
Step-by-step explanation:
Given :-
1. slope= 1/4,y intercept = 42. y-5=-4(x+1)And we need to find the slope intercept form of the line . The slope intercept form of a line is y = mx + c , where m is the slope and c is the y intercept. Substitute respective values ,
Solution 1 :-
[tex]:\implies[/tex] y = mx + c
[tex]:\implies[/tex] y = 1/4 x + 4
[tex]:\implies[/tex] 4y = x + 16
[tex]:\implies[/tex] x - 4y + 16 = 0
Solution 2 :-
[tex]:\implies[/tex] y - 5 = -4( x +1)
[tex]:\implies[/tex] y -5 = -4x -4
[tex]:\implies[/tex] y = -4x +1

YS = 2/3 × ( YV ) *.&.* SV = 1/3 × ( YV )
_____________________________
YS = 2/3 × ( YV )
4x + 14 = 2/3 × ( YV )
Multiply both sides by 3/2
( 4x + 14 ) × 3/2 = ( YV ) × 2/3 × 3/2
YV = 6x + 21 ( ☆ )
¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥
SV = 1/3 × ( YV )
1 + 3x = 1/3 × ( YV )
Multiply both sides by 3
( 1 + 3x ) × 3 = ( YV ) × 1/3 × 3
YV = 9x + 3 ( ♡ )
_____________________________
YV = YV
( ☆ ) = ( ♡ )
6x + 21 = 9x + 3
Subtract both sides 3
6x + 21 - 3 = 9x + 3 - 3
6x + 18 = 9x
Subtract both sides 6x
6x - 6x + 18 = 9x - 6x
18 = 3x
Divide both sides by 3
18 ÷ 3 = 3x ÷ 3
x = 6
₩₩₩₩₩₩₩₩₩₩₩₩₩₩₩₩₩₩
YV = 6x + 21 = 9x + 3
YV = 6(6) + 21 = 9(6) + 3
YV = 57
A man bought a scooter for $100 and sold it for $120. He later bought it back for $140 and sold it again for $160. How much did he make or lose as a scooter salesman? (NO LINKS WILL REPORT WITH OUT HESITATION)
Answer:
Step-by-step explanation:
- 100
+ 120 = 20
-140 = -20
+160 = 20
so every time he sold it, he gained 20 and lost 20 every time he bought it back

In a classroom,1/6,of the students are wearing blue shirts,and 2/3 are wearing white shirts. There are 12 students in the classroom,ow many students are wearing shirts other than blue shirts or white shirts?
Answer:
2
Step-by-step explanation:
1/6 x 12 = 2
2/3 x 12 = 8
8 + 2 = 10
12 - 10 = 2
Answer:
2 not wearing either blue or white
Step-by-step explanation:
Find out the fraction that represents those that are wearing either blue or white. Let x be that fraction
x = 2/3 + 1/6
Change 2/3 and 1/6 to 12ths. because there are 12 students in the class.
2/3 = 2*4 / (4 *O 4) = 8/12
1/6 = 2*1/(2 * 6) = 2 / 12
x = 8/12 + 2/12
x = 10/12 Normally you would reduce this fraction because we are not using the Lowest common Denominator. In this case we just leave it.
There are 12/12 - 10/12 = 2/12 that are missing.
So 2 people are Not wearing either blue or white.
