The bean pod mottle virus (BPMV) is a virus found in soybeans spread by the bean leaf beetle. Concerned with the health of his own field of soybeans, a soybean farmer decided to conduct a small study to compare pesticides. He had 5 acres of land, far from any trees to prevent any area getting less sunlight, that he separated into 30 plots and planted 40 soybean plants per plot. He then randomly chose 10 plots to receive his usual pesticide, 10 plots to receive a new organic pesticide, and the last 10 plots were left untreated (given no pesticide). Also, to maintain constant conditions across the field, each plot was watered equally by the same farmer and using the same equipment. Once the soybean season was over, the farmer recorded the proportion of infected soybean plants from the 40 plants in each of the 30 plots.

How much replication was used in this experiment?

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough

simple 80 pieces in 1 sercing so 80*47=3760+20=3780
