Answer:
Option A
Step-by-step explanation:
Here in this case the respondents differ from the non respondents in more than one ways and hence this results to a nonresponse bias due to which there is an extra thumbs up in support of firing the coach thereby leading to an over estimated number.
Hence, option A is correct
Cos Y=?
5/13
5/12
12/13
Answer:
Cos Y = 12/13
Step-by-step explanation:
Recall, SOHCAHTOA.
Cos Y = Adjacent/Hypotenuse
Reference angle = Y
Adjacent = 12
Hypotenuse = 13
Therefore:
Cos Y = 12/13

Footlocker in the mall is having a 25% off sale on all tennis shoes. Joe paid $67.50 for his
favorite tennis shoes that were on sale. What was the original price of the shoes?
Answer:
The original price of the shoes was $90.
Step-by-step explanation:
25% off means the price Joe paid for it is 75% of the original price.
Set up an equation:
75/100 = 67.50/x
Cross multiply
75 × x = 100 × 67.50
75x = 6750
x = 90
Check our work:
First solve for 25% off of 90 (our answer).
25% = 0.25
90 × 0.25 = 22.50
Next, subtract the discount from 90.
90 - 22.50 = 67.50
67.50 was what Joe paid so this is correct.

Find y
Round to the nearest tenth:
28°
X
350 ft
y
y = [ ? ]ft
Enter
Answer:
y = 658.3 ft
Step-by-step explanation:
Angle of depression = angle of elevation = 28° (alternate angles are congruent)
Reference angle = 28°
Side length opposite to reference angle = 350 ft
Adjacent = y
Apply trigonometric function, TOA:
Tan 28 = Opp/Adj
Tan 28 = 350/y
y*Tan 28 = 350
y = 350/Tan 28
y = 658.254263 ≈ 658.3 ft (nearest tenth)

Step-by-step explanation:
using Pythagoreans theorem
a^2+b^2=c^2
3^2+5^2≈6^2
9+15=34
not 36 so no
Answer :
Here, It is stated that the triangle having sides 3, 5 and 6 respectively. So, we have to prove that whether the given triangle is right angled triangle or not.
For That :
We will be using the Pythagoras Theorem
Given Sides :- Side - A → 3 Side - B → 5Side - C → 6According to the Pythagoras Theorem , the sum of the square of Base side and perpendicular side is equal to the square of the longest side i.e, hypotenuse.
Pythagoras Theorem :
⠀⠀⠀⠀⠀⠀[tex]{\bullet \: {\boxed{\sf {AC^{2} = AB^{2} + BC^{2}}}}} \\ \\ [/tex]
So, here the longest side is Side A of measurement 6.
So, Now
Applying Pythagoras Theorem in it, we get :
The three sides , so let's plug the values in the formula :-
[tex]\dashrightarrow\:\:\sf AC^{2} = AB^{2} + BC^{2}\\ \\[/tex]
[tex]\dashrightarrow\:\:\sf 6^{2} = 3^{2} + 5^{2}\\ \\[/tex]
[tex]\dashrightarrow\:\:\sf 36 = 9 + 5^{2}\\ \\[/tex]
[tex]\dashrightarrow\:\:\sf 36 = 9 + 25 \\ \\[/tex]
[tex]\dashrightarrow\:\:\sf 36 \neq 34 \\ \\[/tex]
[tex]{\underline{\sf {L.H.S \neq R.H.S}}} \\ [/tex]
If in a triangle, the square of the hypotenuse is not equal to the sum of the squares of the other two sides, then the given triangle and doesn't satisfy pythagoras theorem. Hence, Its not a right angled triangle.

Brianna earns $19,500 per year. Lisa earns $1000 per month. Write a numerical expression that represents how much more Brianna earns per year than Lisa
Answer:
$19,500 - $1000
Step-by-step explanation:
the amount Brianna earns in excess of the amount Lisa earns can be determined by subtracting the amount Brianna earns from that Lisa earns
$19,500 - $1000 = $18,500
The law of large numbers tells us that the distribution of a large random sample should resemble the distribution from which it is drawn.
a. True
b. False
Answer:
b. False
Step-by-step explanation:
The law of large numbers, in statistics, says that the experimental average found in a large number of trials should be very close to the theoretical probability. It does not say anything about distribution. So the answer to this question is False, which is given by option b.

A circular clock with a circumference of 88cm is mounted on a wall.How much area of a wall didn't occupy
Answer:
616 cm^2
Step-by-step explanation:
Steps to derive the answer
1. we are going to first determine the radius from the circumference
2. we would calculate the area
Circumference of a circle = 2nr
n = 22/7
r = radius
88 = 2 x 22/7 x r
Divide both sides of the equation by 2 x 7/22
r = 14
Area of a circle = nr^2
3.14 x 14^2 = 616 cm^2

A cartographer used a scale of 1 inch:300 meters for the heights of different mountains. If the actual height of one of those mountains is 3,600 meters, what is its height on the map?
Answer:
The height on the map is of 12 inches.
Step-by-step explanation:
Scale of 1 inch:300 meters
This means that each inch on the map represents 300 meters of real height.
If the actual height of one of those mountains is 3,600 meters, what is its height on the map?
Using proportions, by a rule of three:
1 inch - 300 meters
x inches - 3600 meters
Applying cross multiplication:
[tex]300x = 3600[/tex]
[tex]x = \frac{3600}{300}[/tex]
[tex]x = 12[/tex]
The height on the map is of 12 inches.
The length of a rectangular garden is 8m greater than twice the width the area of the garden is 280m^2 what is the width of the garden
Step-by-step explanation:
Given :-
The length of the garden 8m greater than 2 times the width.
Area of the garden is 280 m²
Let us consider the length as x and width as y.
Sp, we can day length as :-
x = 8 + 2y ---(1)
Now, we know that:-
Area of Rectangle = Length × Breadth
280 = x * y
We can replace the value of x now,
280 = y × ( 8 + 2y)
280 = 8y + 2y²
2y² + 8y - 280 = 0
y² + 4y - 140 = 0
Factorise it.
(y -10)(y + 14)
Cancelling -ve value, we get the width as 10 metres.
Hope it helps :)
Answer:
Step-by-step explanation:
Width = w
Length = 2w + 8
Area of rectangular garden = 280 square meter
length * width = 280
(2w + 8 ) *w = 280
2w * w + 8*w = 280
2w² + 8w = 280
2w² + 8w - 280 = 0
Divide the whole equation by 2
w² + 4w - 140 = 0
w² + 14w - 10w - 14 *10 = 0
w(w + 14) - 10(w + 14) = 0
(w + 14)(w - 10)= 0
w - 10 = 0 {Ignore w + 14, as measurements will not be -ve}
w = 10 m
l = 2*10 +8
= 20 +8
l = 28 m

Help me ASAP plzzzz I’m struggling on this one rlly badly
Answer:
y = -2x + 5
Step-by-step explanation:
Points on the path: (0, 5) and (1, 3)
Slope:
m=(y2-y1)/(x2-x1)
m=(3-5)/(1-0)
m= (-2)/1
m= -2
Slope-intercept:
y - y1 = m(x - x1)
y - 5 = -2(x - 0)
y - 5 = -2x
y = -2x + 5
