Answer:
x=15
Step-by-step explanation:
Since we know that f(x) = -x+5 and f(x)= -10 we can say that -x+5 = -10. When we simplify this, we get that -x=-15 which equals to x=15.
The percentage error in the deer population is 17%
<em>Actual population </em>= 21300
<em>Estimated population</em> = 17600
The percentage error will be calculated by subtracting the estimated population from the actual <em>population</em> and then dividing the result. This will be:
= (<em>Actual population - Estimated population) / Actual population × 100</em>
= (21300 - 17600) / 21300 × 100
= 3700/21300 × 100
= 0.17 × 100
= 17%
Therefore, the percentage error in the <em>deer population </em>is 17%

Answer:
one solution
Step-by-step explanation:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.
A) 0.2076
B) 0.6786
C) 0.3214
Explanation:A)
B) We find the probability that X=6, 7, or 8:
C) P(X≤5) = 1-P(X>5) = 1-0.6786 = 0.3214
