Adam has four short straws, five medium straws, and six long straws. if he randomly draws two straws, one at a time without replacement, what is the probability that both are medium straws?

5/15 or 3rd Chance.

Step-by-step explanation: If you add all of the straws together, and take the amount of medium straws there are: the probability will be limited to the amount of medium straws - of course with the total amount involved. Though, I'm not entirely sure, It's been a while since I've done anything like that.

3rd Chance

Step-by-step explanation:

are they metal straws??? he better be saving the turtles

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
