Answer:
represent the random sample selected
represent the number of pots that were bare ground (no vegetation
And replacing we got:
So then the sample proportion of bare ground spots is 0.792 for this sample
Step-by-step explanation:
We have the following info given from the problem:
represent the random sample selected
represent the number of pots that were bare ground (no vegetation)
And for this case if we want to find the sample proportion of bare ground spots we can use this formula:
And replacing we got:
So then the sample proportion of bare ground spots is 0.792 for this sample
Answer:
McCoy should plant soybeans
Step-by-step explanation:
Thinking process:
Let the two crops be corn and soybeans as indicated.
The profit margin for corn will be $ 30 000. However, the loss will be:
$ 35 000 - $ 30 000 = $ 5 000
For the soybean, the profit margin will be $ 10 000.
The loss will be $ 5 000
The net balance will be given as: $ 5 000 - $ 10 000 = - $ 5 000. (This represents a gain)
Thus, soybean will be more profitable.
Answer:
The answer is option (b), y=-5/2x+4
Step-by-step explanation:
The slope intercept form is a way of expressing the equation of a straight line; where there are two variables that vary in a linear form. The equation is always of the form; y=mx+c
Where;
- y and x represents the variables on the y and x axis respectively
- m is a real number representing the slope
- c is also a real number representing the y-co-ordinate, where the line intercepts the y-axis
Solving for y in 10x+4y=16
(4y)/4=(-10x)/4+(16/4)
The answer is y=-5/2x+4, option (b)
Hello,
If b represents any real number,
b<=-9.5
or
5.5<=b
Answer C
Answer:
$2,000 or 6.25%
Step-by-step explanation:
1000 x 2 = 2000
28000 + 2000 = 30000 Juan's salary after 2 years
500 x 2 = 1000
31000 + 1000 = 32000 Mariana's salary after 2 years
30000 - 32000 = 2000 difference in salary
2000/32000 x 100= 6.25 difference in salary in percentage
