Answer:
8.1
Step-by-step explanation:
1) There are 360 degrees in a circle. Therefore, the arc measure of PQ would be 360-(73+150+65)= 72.
2) The intercepted arc is the same measure as the central, making it 72. Therefore it takes up 72/360 of a circle or 1/5.
3) To find the measure of it, you would find 1/5 of the circumference. C=2πr . C=2(3.14)(6.48)≈ 40.7 .
4) 1/5 of the circumference would be (40.7)/(5)≈8.1
8.1 in.
Answer:
3/2
Step-by-step explanation:
Jacob's (12) to Mark's (8) would be 12 to 8. We want to simplify this. We can divide both numbers by 4 to get 3 to 2. In fraction form would be 3/2.
A) true
b) true
c) true
d) false
e) true
Answer:
$20
Step-by-step explanation:
Bin A: Bin B: Bin W:
white ball: 20% $1: 75% $8: 5/6
black ball: 80% $7: 25% $500: 1/6
first we can calculate the expected return of bins B and W:
expected return if the ball is black = ($1 x 75%) + ($7 x 25%) = $2.50
expected return if the ball is white = ($8 x 5/6) + ($500 x 1/6) = $90
expected return of the game = (expected return of a black ball x probability of choosing a black ball) + (expected return of a white ball x probability of choosing a white ball) =($2.50 x 80%) + ($90 x 20%) = $2 + $18 = $20
Think of 16.4 as 16.40
Also think of 16.5 as<em> 16.50 </em>
Can you name numbers between 40 and 50 ?
16.46
16.49
16.42
Those are all numbers between 16.4 and 16.5
