Which graph represents this system? y = 2 x + 1. y = negative 4 x + 7. On a coordinate plane, a line goes through (0, 7) and (1,

3) and another goes through (1, 3) and (2, 5). On a coordinate plane, a line goes through (negative 4, 0) and (0, 7) and another line goes through (negative 4, 3) and (0, 1). On a coordinate plane, aJessie graphed one of the lines in a system of equations: y = 3 x minus 2. If the system has an infinite number of solutions, which statements are true? Check all that apply. On a coordinate plane, a line goes through (0, negative 2) and (1, 1). Any point in the coordinate plane is a solution because it has an infinite number of solutions. Point (1, 1) is a solution because it is one of the points on the line already graphed. It is impossible to tell if (–1,–5) is a solution without seeing the other line graphed. Point (20, 58) is a solution because it results in a true statement when the point values are substituted into the equation of the line. When the other line in the system is graphed, it will share all points with the line already graphed. (8, 5).

Before a captive breeding program and subsequent reintroduction of the black-footed ferret it is believed that their total popul
irga5000 [103]

Answer:

a) 99.93%

b) 99.98%

Explanation:

Given that:

Total population size was only around 18 individuals ( for  black-footed ferret)

If the annual survival rate in the wild was 0.4%.

a)

What is the probability that all 18 would have died in a single year?

To find that; we multiply the annual survival rate in the wild with the total population; which is:

(0.4%×18) = 0.072%

Then; we subtract it from a total of 100% in order to determine the probability that all 18 would have died in a single year.

= (100.00% - 0.072%)

= 99.93%

b)

What is the probability that all 18 would have died in a single year if canine distemper was present?

Given that;

Because of the presence of canine distemper disease, the annual mortality rate might have been as high as 0.89.

To determine the probability; we have:

1 - Annual mortality rate = annual survival rate

1 - 0.89 = 0.11 %

Therefore, 0.11% of 18 individuals = (0.0011 × 18)

= 0.0198%

Probability that all 18 would have died in a single year if canine distemper was present = 100 - probability of annual survival rate

= (100 - 0.0198)%

= 99.98%

What logical scientific inference can be drawn from the observation that many different species have homologous structures?
Alexus [3.1K]
<h2>Answer:</h2>

Option C) All species with similar anatomical structures are related.

<h2>Explanation:</h2>
  • Homologous Structure: A homologous structure is an example of an organ or bone that appears in different animals, which are anatomically similar structure demonstrating descent from a common ancestor.
  • All species with similar anatomical structures which means they have  homologous structures and are related as they have evolved from a common ancestor.
  • Homologous structures shows divergent evolution.

Result: Option C is the correct scientific inference for homologous structures.

What nursing action is the priority for a client in the second stage of labor?
Margarita [4]
Assessing the perineum for bulging is a nursing priority to a client at the second labor stage. A bulging perineum is caused by the presence of the fetal head against the perineal area and usually signifies imminent birth. Pain medication is not administered this close to the birth instead it crosses the placenta barrier and can cause respiratory distress in the newborn. During this second stage of labor the client is encouraged to push, not pant, with each contraction.
