Answer:
B. Tangent
Step-by-step explanation:
Tangent always makes 90 degree angle with the radius. Now in triangle let's see if it's right angled triangle or not.
To confirm if it's a right angled triangle it should follow Pythagoras Theorem.
Which states square of hypotenuse = sum of squares of other two legs
it proves that it's a right angled triangle. Hence AB is a tangent to circle.
7(1-8n) = 7 - 56n Work - 7 - 7 x 8n= 7 - 56b
-5(1+2k)-8(-4+5k) = 27 - 50k Work - -5-10k+32-40k = 27-10k-40k = 27-50k
Answer:
0.292
Step-by-step explanation:
When we select the first widget, there are 20 good widgets from 25 total.
When we select the second widget, there are 19 good widgets from 24 total.
So on and so forth.
So the probability is:
P = (20/25) (19/24) (18/23) (17/22) (16/21)
P = 0.292
Alternatively, we can calculate this using combinations.
We are selecting 5 widgets from a total of 25. ₂₅C₅
From the 5 defective widgets, we want to select 0. ₅C₀
From the 20 non-defective widgets, we want to select 5. ₂₀C₅
So the probability is:
P = (₅C₀ ₂₀C₅) / ₂₅C₅
P = 0.292
Given:
Area = 21 in²
length = 6 in.
width = ?
The area of a rectangle is computed by multiplying its length by its width.
A = l * w
21 in² = 6 in * w
To find width, divide the area by its length.
21in²/6in = w
3.5 in. = w.
The width is 3.5 inches.
to check:
Area = Length * Width
21 in² = 6 in x 3.5 in
21 in² = 21 in²
