ok for number 2.) 2+8+1+5+1+3+1+7+5+4+3+1=41 and 41 divided by the number of number which is 12= 3.41666666667
the mean for number 2 is 3.41666666667.
for the median you put the number from least to greatest, like so:
1, 1, 1, 1, 2, 3, 3, 4, 5, 5, 7, 8.
The middle is 3 and 3 so 3+3 divided by 2 is 6 so the median is 6.
I cant do mode but range is 8-1 divided by 2
The scale model of a building 3 inches tall if the building is 90 feet tall is 2:5
<h3>Scaling of measurement</h3>
Scaling is the way of enlarging or reducing the image of an object.
Given scale model of a building is 3 inches, if the building is 90feet tall, to write the scale;
Convert both measures to same units
Since 1 feet. = 12 in
90 feet = 90/12 in = 7.5 in
Take the ratio
3 : 7.5 = 30: 75
Reduce to lowest term
30: 75 = 2 : 5
Hence the scale model of a building 3 inches tall if the building is 90 feet tall is 2:5

8x + 5y = 2 → 5y = - 8x + 2 → y = (-8/5)x + 2 ⇒ m = -8/5
perpendicular slope = 5/8
Point-Slope formula: y - y₁ = m(x - x₁) ; where (x₁, y₁) is the given point
y - (-7) = (5/8)(x - 2)
y + 7 = (5/8)(x - 2)
8(y + 7) = 5(x - 2)
8y + 56 = 5x - 10
8y + 66 = 5x
66 = 5x - 8y ⇒ 5x - 8y = 66
Answer: 5x - 8y = 66
3 and 11 are the only two because 33 only has four factors: 1,3,11,33.
1 - in some cases people say this is prime, but it is now widely considered to not be a prime number
3 - prime
11- prime
33 - not prime, divisible by 3 and 11
