Answer:
The graph is misleading because the vertical scale is not even. It goes from 0 to 15 and then thereafter the scale reverts to a scale of 5.
This is misleading because had the graph gone in a scale of 5 from the get go, the number of people who thought 3-4 episodes were too much would have looked higher in the graph as they seem to comprise of about 5% of the sample population.
The scale should begin at 0 and then go like 5 ⇒ 10 ⇒ 15 ⇒ 20 ⇒ 25 ⇒ 30

302 + 299 + 296 + 293 ... + 2 = _____ what is the sequence using Gauss’s Law
By Gauss's Law the approach of solving sum of a sequence of n terms in arithmetic progression is :
[tex]S_n=\dfrac{n}{2}(a_1+a_n)[/tex] ......1 )
Here, [tex]a_n = 302[/tex] , [tex]a_1=2[/tex] .
We know :
[tex]a_n=a_1+(n-1)d\\\\302=2+3(n-1)\\\\n = 101[/tex]
Putting, all values in equation 1) we get :
[tex]S_n=\dfrac{101}{2}\times (2+302)\\\\S_n=101\times 152\\\\S_n=15352[/tex]
Therefore, the sum of sequence using Gauss's Law is 15352.
Hence, this is the required solution.

A basketball player shoots free throws and makes them with probability 1/7. What is the probability of the event the player will miss three in a row?
Answer:
216/343 or 0.6297 (4dp)
Step-by-step explanation:
Anytime the probability of an event occurs more than once in a particular order (one time after another in the same instance), then the probability is multiplied together. If the probability of him making the shot is 1/7, then the probability of him missing it is 6/7. This is because this is the only other possible outcomes and all outcome probabilities must add to 1 (1-1/7 - 6/7).
So, if he misses it three times in a row then the probability is:
6/7 (probability miss this first time) x 6/7 (probability miss second time) x 6/7 (probability miss 3rd time).
6/7 x 6/7 x 6/7 = 216/343
or 0.6297 (4dp)

Elizabeth is a manager at a nursery and is in charge of displaying potted trees in a row Elizabeth has 150 citrus trees and 180 Palm trees she wants to make rows of trees so that each row has the same number of trees and each tree is in the same row. if the citrus trees and the palm trees must not be mixed in the rows what is the largest number of trees she can have in a row
Answer: the greatest number of trees that ElizaBeth can have in a row is 30
Step-by-step explanation:
given data:
citrus trees = 150
palm trees = 180
As we have to find the greatest number of trees that Elizabeth can have in a row, we will find the GCF or greatest common factor.
150 = 2 x 3 x 5 x 5
180 = 2 x 2 x 3 x 3 x 5
Greatest common factor is = 2 x 3 x 5 = 30
Therefore, the largest number of trees that ElizaBeth can have in a row is 30.

Dwayne buys 1 loaf of bread and 6 eggs for $4.45. Sheila buys 1 loaf of bread and 1 dozen eggs for $5.65. Let x be the cost, in dollars, of a loaf of bread. Let y be the cost, in dollars, of an egg.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Let x = cost of a loaf of bread ; y = cost of an egg
Dwayne :
1 loaf of bread and 6 eggs :
X + 6y = 4.45 - - - (1)
Sheila :
X + 12y = 5.65 - - - (2)
From (1);
X = 4.45 - 6y
In (2):
(4.45 - 6y) + 12y = 5.65
4.45 + 6y = 5.65
6y = 5.65 - 4.45
6y = 1.2
y = 0.2
From X = 4.45 - 6y:
X = 4.45 - 6(0.2)
X = 4.45 - 1.2
X = 3.25
Cost of a loaf of bread = $3.25
Coat of an egg = $0.2

SOMEONE HELP I NEED THE ANSWERS TO THIS PROBLEM
Answer:
Step-by-step explanation:
∠6 = 45 {Vertically opposite angles are equal}
∠6 + 5x + 35 = 180 {Co interior angles}
45 + 5x + 35 = 180 {add like terms}
80 + 5x = 180
5x = 180 - 80
5x = 100
x = 100/5
x = 20
5x + 35 = 5*20 + 35 = 100 + 35 = 135
∠8 = 5x + 35 { Corresponding angles}
3) ∠8 = 135
4) ∠ 3 = ∠6 {Alternate interior angles are equal}
∠3 = 45
5) ∠6 = 45
A student rolls a fair die 10 times and obtained an even number 10 times. The student believes that the next roll will
be an odd number because "odds are due."
Is this correct?
Yes, if the die is fair, then an odd number is due because the probability will approach 50%.
No, an even number is due based on past experience.
Yes, it is certain that an odd number will be rolled next because it is impossible to roll an even number 11 times in
a row.
No, an even or odd outcome is equally likely for each roll, regardless of what has happened in the past.

Solve for t.
-3t + 3 – 7t = -90 – 7
Answer:
t = 10Step-by-step explanation:
-3t + 3 - 7t = -90 - 7
Simplify both sides of the equation
That's
- 10t + 3 = - 97
Using the subtraction property subtract 3 from both sides of the equation
We have
- 10t + 3 - 3 = -97 - 3
- 10t = - 100
Divide both sides by - 10
[tex] \frac{ - 10t}{ - 10} = \frac{ - 100}{ - 10} [/tex]
We have the final answer as
t = 10Hope this helps you
Answer:
Step-by-step explanation:
-3t + 3 - 7t = -90 - 7
-10t + 3 = -97
-10t = -100
t = 10
Solve this linear system 28x + 44y = 964.40 21x + 33y = 723.30
28x + 44y = 964.40
21x + 33y = 723.30
Let's multiply the first equation by 4 and the second by -4
84x + 176y = 3857.6
-84x - 132y = -2893.2
Add the equations together.
0 + 44y = 964.4
Simplify
44y = 964.4
Divide both sides by 44
y = 964.4/44
Since we have the value of y, let's plug 964.4/44 into y for the first equation.
28x + 44(964.4/44) = 964.40
Simplify the left side
28x + 964.4 = 964.4
Subtract 964.4 from both sides
28x = 0
Divide both sides by 0
x = 0
In conclusion,
y = 964.4/44
x = 0

What is the area of rhombus ABCD?
Enter your answer in the box. Do not round at any steps.
______units²
Answer:
36 units^2
Step-by-step explanation:
The area of a triangle is 1/2*base*height. Knowing this is just 2 triangles means you solve for 1 triangle, then multiply that by 2
Answer:
[tex]A=36\text{ units}^2[/tex]
Step-by-step explanation:
The area of a rhombus is given by the formula:
[tex]A=\frac{d_1\cdot d_2}{2}[/tex]
Namely, it is half of one diagonal multiplied by the other diagonal.
So, to find the area, we just need to find the length of AC and BD, multiply them together, and then divide by 2.
To find their lengths, we can use the distance formula. The distance formula is:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
So, let's find the lengths of each diagonal:
AC:
Point A is (-1,0) and Point C is (-1,-6). Let (-1,0) be (x₁, y₁) and let (-1,-6) be (x₂, y₂). Substitute this into our formula:
[tex]d=\sqrt{(-1-(-1))^2+(-6-0)^2[/tex]
Simplify:
[tex]d=\sqrt{(-1+1)^2+(-6-0)^2[/tex]
Add or subtract:
[tex]d=\sqrt{(0)^2+(-6)^2[/tex]
Square:
[tex]d=\sqrt{36}[/tex]
Take the square root:
[tex]d=6[/tex]
So, the length of diagonal AC is 6.
BD:
Point B is at (5,-3) and Point D is at (-7,-3). Let (5,-3) be (x₁, y₁) and let (-7,-3) be (x₂, y₂). Substitute this into our formula:
[tex]d=\sqrt{(-7-5)^2+(-3-(-3))^2[/tex]
Simplify:
[tex]d=\sqrt{(-7-5)^2+(-3+3)^2[/tex]
Add or subtract:
[tex]d=\sqrt{(-12)^2+(0)^2[/tex]
Square:
[tex]d=\sqrt{144}[/tex]
Take the square root:
[tex]d=12[/tex]
So, our second diagonal is 12 units long.
Now, to find the area, substitute 6 and 12 into our formula. So:
[tex]A=\frac{d_1\cdot d_2}{2}[/tex]
Substitute 6 for d₁ and 12 for d₂. So:
[tex]A=\frac{(6)(12)}{2}[/tex]
Multiply:
[tex]A=\frac{72}{2}[/tex]
Divide:
[tex]A=36\text{ units}^2[/tex]
So, the area of the rhombus is 36 squared units.
And we're done!
Notes:
Of course, instead of using the distance formula, you can also just count :)
