She would have 12 seeds left from her planting of all packs
Step-by-step explanation:
3,500×4×2/100= 280/100 = $2.80
1 1/4 is the least and 1 2/3 is the greatest.
Answer:
Answer is C
Step-by-step explanation:
I have no step by step explanation but it is C
Calculator instructions will depend on the model/type you have.
- scientific calculator (TI-36pro)
may be a "data" button that opens a table where you can input values.
put the x-values (0,4,8,...) into the first column and the y-values (19,22,25,...) into the second column.
after inputting the values back out and find a "stat-reg/distr" button. Then find the linear regression option "LinReg" or "ax+b"
these setting should already be set but just in case:
x = first column
y = second column
hit calculate
calculator gives the coefficients for the linear equation : y = 2.2292x + 14.9170
r^2 = 0.9682
the r^2 value tells you how well the equation fits the data or how good it will be a predicting unknown values. The closer r^2 is to 1 the better fit it is.
the slope of the line is 2.2292. I'm guessing from the next question.. he data represents women in the house of representatives. If this is the case then the slope represents how many more women per year are in the house of representatives.
2013 - 1980 = 33
This is the x-value you use to find the number of women in the house of representatives in 2013 since x=0 is 1980.
plug this into the equation and solve for y.
y = 88.4806
* you can also use Microsoft excel to generate this information fairly easily instead of a calculator. Just enter the data into columns, highlight them, go to insert tab, click the scatter plot chart (bunch of dots) then right click the dots on the graph and add trendline. check display equation and r^2 value
