Answer:
Right of X = 635.5
Step-by-step explanation:
By using the normal approximation to the Binomial random variable, we usually make use of continuity correction.
According to the rule of continuity;
P(X ≤ k) becomes P( X ≤ K + 0.5)
P(X < K) becomes P(X < K - 0.5)
P(X ≥ K) becomes P(X ≥ K - 0.5)
P(X > K) becomes P(X > K + 0.5)
P(X = K) becomes P(K - 0.5 ≤ X ≤ K + 0.5)
From the given question, Assume that we are to determine the probability that more than 635 Americans support the bill.
Then we use the > sign.
∴
P(X > K ) becomes P(X > K + 0.5)
P(X > 635) becomes P(X > 635 + 0.5)
⇒ P(X > 635.5) tot the right.
Right of X = 635.5

Answer:
The group of all ordered pairs lie on the line is (3, 7), (2, 6), (-2, 2) ⇒ D
Step-by-step explanation:
To solve this type of question, Form the equation of the line and substitute the x-coordinate of each ordered pair to find y, if the value of y equal to the value of the y-coordinate of the point, then the point is on the line
The form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-intercept (value y at x = 0The rule of the slope of the line that passes through points (x1, y1) and (x2, y2) is m = [tex]\frac{y2-y1}{x2-x1}[/tex]From the given figure
∵ The line passes through points (-4, 0) and (0, 4)
∴ x1 = -4 and y1 = 0
∴ x2 = 0 and y2 = 4
→ Substitute them in the rule above
∵ m = [tex]\frac{4-0}{0--4}[/tex] = [tex]\frac{4}{0+4}[/tex] = [tex]\frac{4}{4}[/tex]
∴ m = 1
∵ b is the value of y at x = 0
∵ y = 4 at x = 0
∴ b = 4
→ Substitute the values of m and b in the form of the equation above
∴ y = 1(x) + 4
∴ y = x + 4 ⇒ equation of the given line
Let us check every group
∵ The ordered pairs are (7, 3), (6, 2), (2, -2)
∵ y = x + 4
∵ x = 7
∵ y = 7 + 4 = 11
∵ y-coordinate = 3
∴ Point (7, 3) doesn't lie on the line
∵ The ordered pairs are (5, 1), (3, 7), (2, 6)
∵ x = 5
∴ y = 5 + 4 = 9
∵ y-coordinate = 1
∴ Point (5, 1) doesn't lie on the line
∵ The ordered pairs are (3, 7), (2, 6), (2, 2)
∵ x = 3
∴ y = 3 + 4 = 7
∵ y-coordinate = 7
∴ Point (3, 7) lies on the line
∵ x = 2
∴ y = 2 + 4 = 6
∵ y-coordinate = 6
∴ Point (2, 6) lies on the line
∵ x = 2
∴ y = 6
∵ y-coordinate = 2
∴ Point (2, 2) doesn't lie on the line
∵ The ordered pairs are (3, 7), (2, 6), (-2, 2)
∵ x = 3
∴ y = 3 + 4 = 7
∵ y-coordinate = 7
∴ Point (3, 7) lies on the line
∵ x = 2
∴ y = 2 + 4 = 6
∵ y-coordinate = 6
∴ Point (2, 6) lies on the line
∵ x = -2
∴ y = -2 + 4 = 2
∵ y-coordinate = 2
∴ Point (-2, 2) lies on the line
∵ The three ordered pairs lie on the line
∴ The group of all ordered pairs lie on the line is (3, 7), (2, 6), (-2, 2)
∵ The ordered pairs are (1, 5), (-6, 2), (-7, -3)
∵ x = 1
∴ y = 1 + 4 = 5
∵ y-coordinate = 5
∴ Point (1, 5) lies on the line
∵ x = -6
∴ y = -6 + 4 = -2
∵ y-coordinate = 2
∴ Point (-6, 2) doesn't lie on the line

· Amanda has $210 in her school lunch account. She spends $35 each week on school lunches. The
equation a = 210 - 35w represents the total amount in Amanda's school lunch account a for w
weeks of purchasing lunches.
Answer:
(See step-by-step)
Step-by-step explanation:
Let’s start by making A-(X) and W-(Y). So, when substituting the variables you get x=210-35y. When x=0, the answer to the equation is 6. So, the y-intercept (when x=0) is 6 or (0,6). When y=0, the answer to the equation/x-intercept(y=0) is 210 or (210,0). The graph itself looks like the image included.
The domain, realistically, is x>=0 however on the graph itself, the domain is x= All Real Numbers. The range realistically is y>=0, but on the graph it is also All Real Numbers.
The x-intercept is the account when no weeks have passed and no money is lost (210) and the y-intercept is the maximum amount of weeks before there is no more money in the account (6).

a circle has a diameter of 5 inches. What is the area of the circle in terms of pi
Answer:
The area of the circle is [tex]\mathbf{6.25\pi}[/tex]
Step-by-step explanation:
Area of a Circle
A circle of radius r has an area calculated by the following formula:
[tex]A=\pi r^2[/tex]
The diameter of a circle is twice the radius, thus the radius is half the value of the diameter.
A given circle has a diameter of 5 inches.
The radius of this circle is r = 5/2 = 2.5 inches.
Thus, the area is calculated below:
[tex]A=\pi 2.5^2 = 6.25\pi[/tex]
The area of the circle is [tex]\mathbf{6.25\pi}[/tex]

Answer:
srt is 33
srq is 66
trq is 33
Answer:
∠SRT = 33°
Step-by-step explanation:
To track what angle they're talking about, connect the letters listed for each angle like connect the dots.
∠QRT is 33°
RT bisects ∠SRQ, meaning it's in the middle of it.
So half of ∠SRQ is 33°, meaning the full angle is double that: 66°
That also means that the other half of the angle is equal to the first half. ∠SRT=33°

Answer:
The Perimeter of a rectangle will be:
P = 252 in
Hence, option (E) is true.
Step-by-step explanation:
Given the rectangle with the sides
length [tex]l[/tex] = 14-5 inWith [tex]w[/tex] = 7×4 inWe know that the Perimeter of a rectangle can be calculated using the formula
[tex]P = lw[/tex]where l is the length, and w is the width
substituting [tex]l[/tex] = 14-5, [tex]w[/tex] = 7×4
P = (14-5) × (7×4)
P = 9 × 28
P = 252 in
Therefore, the Perimeter of a rectangle will be:
P = 252 in
Hence, option (E) is true.

6 21
8 28
10 35
14 49
Answer:
[tex]y = 3.5x[/tex]
Step-by-step explanation:
Required
Determine the equation
First, pick corresponding x and y values
[tex](x_1,y_1) = (6,21)[/tex]
[tex](x_2,y_2) = (14,49)[/tex]
Next, calculate the slope
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
This gives:
[tex]m = \frac{49 - 21}{14 - 6}[/tex]
[tex]m = \frac{28}{8}[/tex]
[tex]m = 3.5[/tex]
The equation is then calculated using:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 21 = 3.5(x - 6)[/tex]
[tex]y - 21 = 3.5x - 21[/tex]
Add 21 to both sides
[tex]y - 21+21 = 3.5x - 21+21[/tex]
[tex]y = 3.5x[/tex]
A friend offers to play a game, in which you roll 3 standard 6-sided dice. If all the dice roll
different values, you give him $1. If any two dice match values, you get $2. What is the expected value of this game?
Answer: The expected value is $0.32
Step-by-step explanation:
The expected value can be calculated as:
EV = ∑xₙ*pₙ
Where:
xₙ is the n-th event.
pₙ is the probability of the n-th event.
First, let's see the events in this situation and the probability of each event.
Lossing $1.
This happens when you roll all different numbers.
To calculate the number of combinations where you roll all different values, we first need to count the number of possible options for each roll, this is:
First dice: you have 6 options
Second dice: You have 5 options, because we remove the option that was rolled in the first dice.
Third dice: You have 4 options, because we removed the two outcomes showed in the two previous rolls.
Then the number of combinations is:
c = 6*5*4 = 120.
And the total number of combinations for rolling 3 dice is equal to the product between the number of outcomes for each dice, each dice has 6 possible outcomes, then the total number of outcomes is:
C = 6*6*6 = 216
The probability of rolling all different numbers will be equal to the quotient between the number of combinations where you roll all different values and the total number of combinations:
P₁ = 120/216 = 0.56
In the other case, where you roll at least two equal outcomes, you win $2.
The probability for this case will be the complement of the previous one, then the probability can be calculated as:
P₂ = 1 - P₁ = 1 - 0.56 = 0.44
Then the expected value will be:
EV = -$1*0.56 + $2*0.44 = $0.32
The expected value is $0.32

How to identify the type of conic section from an equation?To of identify the type of conic section from an equation whether it is parabola, or not, let suppose the equation as,
[tex]Ax^2+By^2+Cx+Dy+E=0[/tex]
If In this equation,
Either [tex]A=0[/tex] or [tex]B=0[/tex], but not both. Then it is the equation of parabola.
The first equation is,
[tex]-5x^2 + 4x - 7y + 14 = 0[/tex]
There is no square term of y. Thus, this is the equation of parabola.
The second equation is,
[tex]-x^2 + 6x + y^2 - 8 = 0[/tex]
This is not the equation of parabola, as there is two square terms of variable x and y.
The third equation is,
[tex]9x^2 - 12xy + 4y^2 + 4x - y + 5 = 0[/tex]
Similar to the second equation, here is also two square terms of different variable. Thus, it is not a equation of parabola.
The fourth equation is,
[tex]12x + 6y -5y^2 + 14 = 0[/tex]
This equation is the equation of parabola, as there is only a single square term.
The fifth equation is,
[tex]20x^2 + 10xy - y^2 + 3x - 6y + 5 = 0[/tex]
This is now the equation of parabola because of two square terms.
Hence, the equation which would produce a parabola from the provided options are equation first and forth,
[tex]-5x^2 + 4x - 7y + 14 = 0[/tex]
[tex]12x + 6y -5y^2 + 14 = 0[/tex]
