Answer:

y = 1x + 1/2

Step-by-step explanation:

y2 - y1 / x2 - x1

2 - 3/2 / 3/2 - 1

= 1/2  / 1/2

= 1

y = 1x + b

3/2 = 1(1) + b

3/2 = 1 + b

1/2 = b

In a genetics class, 6 students have GREEN eyes, 5 students have BLUE eyes, and 9 have HAZEL eyes. If a single student is picked
mixer [17]

EXPLANATION:

Given;

We are given that in a class there are the following groups of students;

\begin{gathered} Green\text{ }eyes=6 \\ Blue\text{ }eyes=5 \\ Hazel\text{ }eyes=9 \end{gathered}

Required;

We are required to calculate the probability that a student selected at random will have Green eyes OR Blue eyes.

Step-by-step solution;

To calculate the probability of an event, we shall use the following formula;

P[Event]=\frac{Number\text{ }of\text{ }required\text{ }outcomes}{Number\text{ }of\text{ }all\text{ }possible\text{ }outcomes}

To calculate the probability that a selected student will have green eyes;

P[green]=\frac{6}{20}=\frac{3}{10}

To calculate the probability that a selected student will have blue eyes;

P[blue]=\frac{5}{20}=\frac{1}{4}

The probability of event A or event B will be the addition of probabilities.

Therefore, the probability that a randomly selected student will have green or blue eyes will be;

P[G]+P[B]=\frac{3}{10}+\frac{1}{4}P[F]+P[B]=\frac{6}{20}+\frac{5}{20}=\frac{11}{20}

Therefore,

ANSWER:

P[G\text{ }orB]=\frac{11}{20}

A sporting goods store manager wants to forecast annual sneaker revenues based on the type of sport (running, tennis, or walking
Naddik [55]

Answer:

The manager should include 7 independent variables in her multiple regression analysis.

Step-by-step explanation:

Lets consider sales revenue to bethe dependent variable and, type of sport, color, and target audience, the categorical variables represented with dummy variables. Just remeber that one fewer dummy variables than the number of options in a category must be used, so, type of sport should be represented by: 3 - 1 = 2 dummy variables

color should be represented by 5 - 1 = 4 dummy variables, and

target audience should be represented by 2 - 1 = 1 dummy variables

This totalizes:  2 + 4 + 1 =7   independent variables.

If a household appliance has a wattage of 7,043 and is in use for 9 hours, how much CO2 was produced? Round to 1 decimal.
fgiga [73]

Answer: = 62.8 pounds of CO₂

Step-by-step explanation:

1 kilowatt per hour produces 0.99 pounds of C02.

The total wattage in hours used was;

= 7,043 * 9 hours

= ‭63,387‬ watts

In kilowatts;

= ‭63,387‬/1000

= 63.387 kilowatts

CO2 produced;

= 63.387 * 0.99

= ‭62.75313‬

= 62.8 pounds of CO2
