Answer:
The correct option is d. 0.60
Step-by-step explanation:
Consider the provided information.
At Mike’s favorite coffee shop, the coffee of the day is either a dark roast, a medium roast, or a light roast.
The coffee being a light roast is 0.15 and the probability of the coffee being a dark roast is 0.25.
Pr(Light roast) = 0.15
Pr(Dark roast) = 0.25
We need to find the probability of the coffee of the day not being a light roast or a dark roast on the next day that Mike visits the coffee shop.




Hence, the correct option is d. 0.60
Answer:
400milliliters
Step-by-step explanation:
Let x=ml of 30% solution B used in resulting mixture.
800+x=ml of resulting 30% solution
40%(800)+10%x=30%(800+x)
Then we can simplify the expression
0.4(800)+0.10x= 0.30(800+x)
320+0.10x=240+0.30x
80=0.20x
x= 400milliliters
Therefore, 400milliliters of 10% solution B used in resulting mixture.
Answer:
-0.5°C every hour
Step-by-step explanation:as the temperature of the bottom of the mountain changed at 1/5 the rate of temperatures change on the top of the mountain, so, the hourly rate of temperature change at the bottom of the mountain is=
-2.5×(1/5)
=-0.5
40 x 3 = 120 students study languages
there are 40 students in each language class and there are 3 language classes.
hope it's clear :)
