Answer:

Approximately 24–36 pounds

Step-by-step explanation:

Given:

Weight of standard American Eskimo dog has mean= 30 pounds

A standard deviation= 2 pounds

For 99.7% of the dogs according to normal distribution would lie between 3 standard deviations on either side of the mean.

i.e. lower bound= Mean- 3 (standard deviation)

= 30-3(2)

=30-6

=24

Upper bound = Mean +3 (standard deviation)

= 30+3(2)

=30+6

=36

Hence the range of weights : 24-36 pounds

correct answer Approximately 24–36 pounds!

Which graph shows data that would result in the most accurate prediction of the number of games a baseball team will win in a se
Lynna [10]

Any graph that can be used to accurately predict number of games a baseball team will win in a season based on the total number of home runs scored that season will be a graph that has home runs on the x-axis and wins on the y-axis.

<h2>Straight line graph</h2>

A straight line graph is a graph that obeys the equation; y = mx + c

  • m = slope
  • c = intercept

For there to be the possibility of prediction, the graph must increase or decrease linearly.

Therefore, any graph that can be used to accurately predict number of games a baseball team will win in a season based on the total number of home runs scored that season will be a graph that has home runs on the x-axis and wins on the y-axis. Points are grouped together in a line and increase.

During a sale at the bookstore,books sold for $3 and magazines sold for $2.50.Jan spent $16 and bought a total of 6 books and ma
quester [9]

<span>If you would like to know how many of each did Jan buy, you can calculate this using the following two equations:

b ... the number of books
m ... the number of magazines

$16 = b * $3 + m * $2.50 ... 16 = 3 * b + 2.50 * m
b + m = 6 ... b = 6 - m
__________________
</span>16 = 3 * b + 2.50 * m

<span>16 = 3 * (6 - m) + 2.50 * m</span>

16 = 3 * 6 - 3 * m + 2.50 * m

16 - 18 = - 3 * m + 2.50 * m

- 2 = - 0.50 * m     /0.50

m = 2 / 0.50

m = 4 magazines 

<span>b = 6 - m = 6 - 4 = 2 books</span>

Result: Jan bought 4 magazines and 2 books.
