When the sample is given, the number of elk are likely to be infected is to be considered as the 450.
<h3>Calculation of the number of elk:</h3>
Since the population is 7,500.
The random sample is 50.
So here be like
÷ 
× 
= 450
hence, When the sample is given, the number of elk are likely to be infected is to be considered as the 450.

Split it out and solve it !!
6(4a^2+11)- 13(3a-2a^2)-28
24a² + 66 - 39a +26a² - 28
50a² - 39a + 38
The answer is b my guy :)
Answer:
Dimension of room = 18 foot x 18 foot
Step-by-step explanation:
Let the square room is of side a foot,
The cost of re-finishing the hardwood floors is $2.25 per square foot and the cost of purchasing and installing the new baseboards $14.5 per linear foot
Total cost is $1773.
Cost for re-finishing the hardwood floors = Area x 2.25
Area = a²
Cost for re-finishing the hardwood floors = 2.25 a²
Cost of purchasing and installing the new baseboards = Perimeter x 14.5
Perimeter = 4a
Cost of purchasing and installing the new baseboards = 4a x 14.5 = 58 a
Total cost = Cost for re-finishing the hardwood floors + Cost of purchasing and installing the new baseboards
1773 = 2.25 a² + 58a
2.25 a² + 58a - 1773 = 0
a = 18 or a = -43.77(not possible)
Dimension of room = 18 foot x 18 foot
Answer:
So since the 2 angles are congruent they will be the same.
Step-by-step explanation:
So since the 2 angles are congruent they will be the same. So for example, if I have a triangle and angle 60 and two congruent angles it will be 60 + 2x =180. I congruent angle will be x then 2 of that is 2x. Angles in a triangle always sum up to 180.
