Misha Larkins [42]3 years ago
3 0

Answer:

y=-30x+210

Step-by-step explanation:

Let

x -----> the number of days

y ----> the number of minutes Yuson has left

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-coordinate of the y-intercept (initial value)

In this problem we have

The slope is equal to

m=-30\frac{min}{day} ----> is negative because is a decreasing function

b=210\ min ----> initial value

substitute the values

y=-30x+210

Kelly Slater and Andy Irons are in a surf competition among 10 competitors.
Delvig [45]

Answer:

The probability that Kelly will place 1st and Andy will place 2nd is 1/90, or 1.11%.

Step-by-step explanation:

Since Kelly Slater and Andy Irons are in a surf competition among 10 competitors, to determine, if all surfers are at an equal surfing level, then what is the probability that Kelly will place 1st and Andy will place 2nd, the following calculation must be performed:

1/10 x 1/9 = X

0.1 x 0.11 = X

0.01111 = X

1/90 = 0.011111 = X

Therefore, the probability that Kelly will place 1st and Andy will place 2nd is 1/90, or 1.11%.
