The table shows the growth, in centimeters, of plants in two different soils after two weeks.Which statement explains which soil tended to have a greater growth?

Soil A had greater growth because its data have a greater standard deviation.
Soil A had greater growth because its data have a greater mean.
Soil B had greater growth because its data have a greater interquartile range.
Soil B had greater growth because its data have a greater median.

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

Given is a table about plants growth in soil A and B.

Let us find mean and median.

Soil A

Mean: 4.17

Median: 3.9

Mode: 3.5

Minimum: 3.1

Maximum: 6

Range: 2.9

Count: 10

Sum: 41.7

Soil B

Mean: 4.28

Median: 4.25

Mode: 3.9

Minimum: 2.9

Maximum: 5.5

Range: 2.6

Count: 10

Sum: 42.8

Soil B shows a better growth since both mean and median are greater.

Answer 2

Answer:

it Might be D. Soil B had greater growth because its data have a greater median.

A giant bamboo plant grew an average of 18 centimeters per year.The botanist started measuring the plant when it was 5 centimeters tall. If "Y" represents the number of years the botanist has measured the plant,what expression represents its height?Solve,and show each step.

Answers

h=height
y=number of years.

we have the next expresion:
h(y)=my+b

m=the slope of the line, in this case, the slope is equal to "18"; (18 cm/ year).
b=the initial heigth, in this case, the initial heigth is equal to "5" (5 cm).

Therefore, our expression will be:
h(y)=18y +5

answer: h(y)=18y+5

A salesperson receives a base salary of $35,000 and a commission of 10% of the total sales for the year. a.) Write a linear model that shows the salesperson’s total income based on total sales of k dollars. b.) If the salesperson sells $250,000 worth of merchandise, what is her total income for the year, including her base salary?

Answers

Answer:

Part a) The linear model that shows the salesperson’s total income is equal to

$0.10k+\$35,000$

Part b) The total income is $\$60,000$

Step-by-step explanation:

Part a)

Let

k-------> the total sales for the year

y-----> the total income for the year

we know that

The linear equation that represent the situation is

$y=0.10k+\$35,000$

Part b) we have

$k=\$250,000$

substitute the value of k in the linear model to find the total income

$y=0.10(\$250,000)+\$35,000$

$y=\$25,000+\$35,000$

$y=\$60,000$

Final answer:

The salesperson's income is represented by the linear model y = 35000 + 0.10k. If they sell $250,000 of merchandise, their total income, including salary and commission, would be $60,000.

Explanation:

A) The total income of the salesperson can be represented by the linear equation y = 35000 + 0.10k, where y represents the total income including the base salary and commission, and k represents the total sales.

B) To calculate the total income for a certain amount of sales, you would substitute the total sales amount into the equation. If the salesperson sold $250,000 worth of merchandise, the total income would be y = 35000 + 0.10*250000 = 35000 + 25000 = $60,000.

The salesperson would earn a total of $60,000 including base salary and commission for the year for the sales of $250,000 worth of merchandise.

How do I identify rational and irrational numbers?

Answers

Answer: An irrational number is a number that is NOT rational. It cannot be expressed as a fraction with integer values in the numerator and denominator. When an irrational number is expressed in decimal form, it goes on forever without repeating.

An irrational number can be written as a decimal, but not as a fraction. An rational number can be written as a ratio.
