Me out !
a spinner has 10 equally sized sections, 6 of which are gray and 4 of which are blue. the spinner is spun twice. what is the probability that the first spin lands on blue and the second spin lands on gray? write your answer as a fraction in simplest form.

6/25

Step-by-step explanation:

To solve this we first need to know the probability for landing on a gray section and the probability of landing on a blue section:

Probability of gray - 6/10 or 3/5

Probability of blue - 4/10 or 2/5

Now that we know this, the question asked us to find the probability we will spin blue and than gray. We know that these events are independent of each other meaning that one outcome will not affect the probability of another outcome. Therefore in order to find the probability of blue then gray we can just multiply the probability of landing on gray (3/5) by the probability of landing on blue (2/5).

3/5 x 2/5 = 6/25

I hope this helps!

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
