Answer:
3
Step-by-step explanation:
Usually, when there is contamination the smallest amount can have huge ramifications in the data collected. In this scenario, if in a "clean" environment the trait is found in 2/10 frogs then anything above this number should be considered contaminated. This is because data above this ratio would be considered uncommon or rare and this unique occurrence can be most likely tied to the only new factor which would be the contamination. Therefore the minimum number of frogs with this trait in the sample would be 3.
Answer:
i believe it is 21.285 or 21.29 since yo multiply 5.50 times 3.87 to get 21.285

Answer:
3x + 2y = 31
Step-by-step explanation:
Solve the given equation for y to determine the slope of this line:
-3y = -2x = -18, so that y = (2/3)x + 6.
Therefore, a line perpendicular to the given line has the slope -3/2, which is the negative reciprocal of this 2/3.
Using the slope-intercept formula y = mx + b and inserting the knowns (slope = m = -3/2, y = 5 and x = -7), we obtain:
5 = (3/2)(-7) + b, or (after multiplying all terms by 2):
10 = -21 + 2b, or 2b = 31, or b = 31/2.
Then the equation is y = (-3/2)x + 31/2.
Let's put this into standard form. Multiply all terms by 2, obtaining:
2y = -3x + 31, or
3x + 2y = 31 This is the equation of the perpendicular line in question.
Answer:
solution is (10/3 , -7/3) for y = (1/2)x - 4 and y = 2x - 9
Step-by-step explanation:
y = (1/2)x - 4
y = 2x - 9
2x - 9 = (1/2)x - 4
(3/2)x = 9 - 4
(3/2)x = 5
x = 10/3
y = 2*(10/3) - 9 = 20/3 - 9 = 20/3 - 27/3 = -7/3
solution is (10/3 , -7/3) unless you meant to write y = x - 4 and y = 2x - 9
if so then x - 4 = 2x - 9 x = 5... but this is not in your solution set.
