Answer: class B
Explanation:
Normal distributions are bell-shaped and symmetric about the mean. So, if the data is scattered around a lot, like in Class A & B, it would not be normal.
In a tangent segment, no part of it is in the interior of the circle. with a secant, there is a part in the interior called the chord. hope it helps
if you need help with anything else just ask me
Answer:
x = 1 and y = 11
Step-by-step explanation:
To start, let's substitute in y into the first equation. We will get 5x + 3 (3x + 8) = 38. Now, distribute the 3 in the 2nd term to get 5x + 9x + 24 = 38. Add like terms to get 14x + 24 = 38, and subtract 24 from both sides to get 14x = 14. Now, divide both sides by 14 to get x = 1. Plug this back in to get that y = 11.
Answer:
Step-by-step explanation:
Assuming it is supposed to be y = 2- (x+1)
y= x-1
or if it is supposed to be y = -2(x+1)
y= -2x-2
We know that
l² = r² + h²
l² = (10.5)² + (36)²
l² = 110.25 + 1296
l² = 1406.5
l = √(1406.5)
l = 37.5 cm
Now,
CSA of cone = πrl
=> 22/7 × 10.5 × 37.5
=> 22 × 1.5 × 37.5
=> 1237.5 cm²
Area of 20 caps = 20 × 1237.5
=> 24750 cm²
