Step-by-step explanation:
there are some coloured pins in a bag
Answer:
Green is 0.3, Yellow is 0.1
There are 12 green pins in the bag
Step-by-step explanation:
The probability is the ratio between the possible outcomes over the total outcomes
The value of the probability of possible outcomes is greater than 0 and smaller than 1 (0 < P < 1)The sum of the probabilities of all outcomes must equal 1∵ A bag contains some green, yellow, purple and grey pins
∵ The probability of picking a purple pin P(purple) = 0.35
∵ The probability of picking a grey pin P(grey) = 0.25
→ The total of all possible outcomes is 1
∴ The sum of the probability of green and yellow pins = 1 - 0.35 - 0.25
∴ The sum of the probability of green and yellow pins = 0.4
∴ P(green) + P(yellow) = 0.4 ⇒ (1)
∵ The probability of picking a green pin is 3 times the probability
of picking a yellow pin
∴ P(green) = 3 P(yellow) ⇒ (2)
→ Substitute (2) in (1)
∴ 3 P(yellow) + P(yellow) = 0.4
∴ 4 P(yellow) = 0.4
→ Divide both sides by 4
∴ P(yellow) = 0.1
∴ The probability of picking a yellow pin is 0.1
→ Substitute P(yellow) in (20 by 0.1
∴ P(green) = 3(0.1)
∴ P(green) = 0.3
∴ The probability of picking a green pin is 0.3
∴ Green = 0.3, Yellow = 0.1
∵ There are 14 purple pins in the bag
∵ P(purple) = 0.35
∴ 0.35 of purple pins = 14
→ To find the total number of pins in the bag divide 14 by 0.35
∴ The total number of pins = 14 ÷ 0.35
∴ The total number of pins = 40 pins
∵ P(green) = 0.3
∴ The number of green pins = 0.3 × 40
∴ The number of green pins = 12 pins
∴ There are 12 green pins in the bag

Constitution Hall was undergoing some major renovations, so no one was able to schedule a performance there.
Answer:
Constitution Hall was owned by the Daughters of the American Revolution (DAR), who refused to let African Americans perform there.
Step-by-step explanation:
The Daughters of the American Revolution proudly practices a non-discrimination policy and encourages and celebrates diversity in our organization. However, in 1939, opera singer Marian Anderson was denied the opportunity to perform in DAR Constitution Hall because of her race.

HELP THiS IS DUE In 30 MINUTES
Answer:
undefined
Step-by-step explanation:
The x coordinate of the two points are the same, while the y values are different. This means that the line is vertical. A vertical line does not have a defined slope, because the change in y divided by the change in x is dividing by zero. Therefore, the answer is "undefined"
Answer:
The slope of the line is undefined.
Step-by-step explanation:
Using the point slope formula, in the end, you will get -7 over 0. Since a zero is in the bottom, the slope is considered undefined.

(x-6)(x2+2x-4)
Answer:
x³ - 4x² - 16x + 24
Step-by-step explanation:
Step 1: Write expression
(x - 6)(x² + 2x - 4)
Step 2: Distribute each term
x³ + 2x² - 4x
-6x² - 12x + 24
Step 3: Combine
x³ + 2x² - 4x - 6x² - 12x + 24
Step 4: Combine like terms
x³ - 4x² - 16x + 24
Find the equation of the perpendicular bisector of a line segment whose end points are (-3,9) and (-1,5)
First find the equation of y.
[tex]y=mx+n=\frac{\Delta y}{\Delta x}x+n[/tex]
Find the slope m.
[tex]m=\frac{5-9}{-1-3}=\frac{-4}{-4}=1[/tex].
Pick one point, I'll pick (-3, 9). Insert coordinates in equation then compute n.
[tex]9=1(-3)+n\implies n=12[/tex].
The equation of a line y is:
[tex]y=x+12[/tex].
The perpendicular line [tex]y_{\perp}[/tex] is same like the normal line except its slope m becomes:
[tex]k=-\frac{1}{m}=-1[/tex].
The equation of a perpendicular bisector is thus:
[tex]y_{\perp}=-x+12[/tex].
Hope this helps.
Answer:
[tex]y = \frac{1}{2} x + 3[/tex]
Step-by-step explanation:
Using the given points, first find the slope:
m = (₂ - y₁) / (x₂ - x₁)
= (5 - 9) / (-1 - (-3))
= -4 / 2
= -2
Find y-intercept by using anyone of the give points and slope from above:
y = mx + b
5 = -2(-1) + b
5 = 2 + b
b = 3
With the m and b, you can make equation of line:
y = mx + b
y = -2x + 3
To find the perpendicular slope, make it opposite and inverse it.
m = -2 becomes 1/2
Regular equation of line:
y = -2x + 3
Perpendicular equation of line:
[tex]y = \frac{1}{2} x + 3[/tex]
Solve the system of equations by using substitution. Give your final answer in the form of an ordered pair.
5x - 2y = 26
y + 4 = x

What is the scale factor of dilation?
1 over 2
1 over 3
1 over 4
1 over 5
Answer: 1 over 2
Step-by-step explanation: if you take the coordinates of the pre-image, letter A. which is (2,6) and the coordinates of the transformed image A’ which is (1,3) and only use the first number of the coordinates. You would put the number of of the pre-image as the denominator and the number of the transformed image as the numerator. And It would become 1/2.

Quadration Equation
X^2 - 6x - 7 = 0
Answer:
x = - 1, x = 7
Step-by-step explanation:
Given
x² - 6x - 7 = 0
Consider the factors of the constant term (- 7) which sum to give the coefficient of the x- term (- 6)
The factors are - 7 and + 1, since
- 7 × 1 = - 7 and - 7 + 1 = - 6, thus
(x - 7)(x + 1) = 0
Equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x + 1 = 0 ⇒ x = - 1
