Answer:

y = -13x + 4

Step-by-step explanation:

You want to put it in the form y = mx + b where m is the slope and b is the y-intercept (For example, in the equation y = 2x + 3 the slope is 2 and the y-intercept is 3)

Since the slope is -13, m = -13.

Since the y-intercept is 4, b = 4.

This means the equation is y = -13x + 4

During the cold winter months, a sheet of ice covers a lake near the Arctic Circle. At the beginning of spring, the ice starts t

Masja [62]

Answer: The ice sheet's thickness decrease every 6 weeks= 1.5 meters

Step-by-step explanation:

GIven: At the beginning of spring, the ice starts to melt. The variable sss models the ice sheet's thickness (in meters) t weeks after the beginning of spring. $s=-0.25t+4$

At t=0, $s=4$

So, Thickness of ice sheet at the beginning = 4 meters

Now at t= 6, we get

$s=-0.25(6)+4=-1.5+4=2.5$

Thickness of ice sheet after 6 weeks = 2.5 meters

Decrease in thickness = 4 meters - 2.5 meters = 1.5 meters

Hence, the ice sheet's thickness decrease every 6 weeks= 1.5 meters

A bag contains blue and pink balls. There are 8 more blue balls than pink balls. Identify the expression that represents the pro

8_murik_8 [283]

Let
b---> the original amount of blue balls in the bag
p---> the original amount of pink balls in the bag

we know that
b=8+p
p=5
so
b=8+5----> b=13

step 1
Find the total of balls originally in the bag
total =13+5-----> 18

step 2
find the probability that a person will pick a blue ball first
Find P(b)
P (b)=13/18

step 3
Find the probability that a person will pick a pink ball second without replacement
the total of balls now is (18-1)-------> 17
P(p)=5/17

step 4
Find the probability that a person will pick a blue ball first and then a pink ball without replacement
(13/18)*(5/17)-----> (13*5)/(18*17)------> 65/306-----> 0.21

the answer is
0.21
