Answer:

y=2x+3

Step-by-step explanation:

we know the slope is 2

now we are going to find b

-1=2(-2)+b

-1=-4+b

-1+4=3

3=b

Write a linear function that passes through (1,5) and (2,15)

Leokris [45]

Simple,

using $\frac{y1-y2}{x1-x2} =m (slope)$

find your slope...

$\frac{5-15}{1-2} = \frac{-10}{-1}=10$

thus, 10=m (slope)

Now, using y=mx+b to find your equation, plug in what you know...

Use any of the 2 coordinates.. (1,5)

5= 10(1)+b

5=10+b
-10 -10

-5=b

Thus, the equation to your line is...

y=10x-5.

a survey of lobster fishermen found that they catch an average of 32 pounds of lobster per day with a standard deviation of 4 po

icang [17]

There is a probability of 22.66% that their average catch is less than 31.5 pounds

<h3>What is z score?</h3>

The z score is used to determine by how many standard deviations the raw score is above or belaw the mean. It is given by:

z = (raw score - mean)/ (standard deviation ÷ √sample)

Given that, mean = 32, std = 4, sample = 36, hence:

For 31.5:

z = (31.5 - 32) / (4 ÷√36) = -0.75

P(z < -0.75) = 0.2266

There is a probability of 22.66% that their average catch is less than 31.5 pounds
