Enzo is studying the black bear population at a large national park.
Naddik [55]

Answer:

2,973

Step-by-step explanation:

The black bear population B(t), in the park is modeled by the following function:

B(t) = 2500 \cdot 2^{0.01t}

Where t is the time(in years) elapsed since the beginning of the study.

We want to determine the black bear population in 25 years time, t=25.

B(25) = 2500 \cdot 2^{0.01*25}\\=2973.02\\\approx 2973

There will be 2,973 black bears in 25 years time.

Find the area and perimeter of the square 6 meters
Mkey [24]
<h2>AREA</h2>

The formula for finding area of a square is:

length \times width

In a square, all the sides are the same. Each side is 6 meters long. Plug in 6 to the formula.

length \times width \rightarrow 6 \times 6

Multiply:

6 \times 6 = 36

The area of the square is 36 m²

<h2>PERIMETER</h2>

Perimeter is the distance around a shape. To find perimeter, you have to add all all the side lengths. The formula for finding perimeter is:

2(l) \times 2(w)

Remember that squares have 4 sides, and all length(s) and width(s) measure the same. The length and width measure the same. Plug in the numbers into the formula:

2(l) + 2(w) \rightarrow 2(6) + 2(6)

Simplify:

2(6) + 2(6) = 12 + 12

Add:

12 + 12 = 24

The perimeter of the square is 24 m

There are black, blue, and white marbles in a bag. The probability of choosing a black marble is 0.36. The probability of choosi
Gala2k [10]

Answer: c) 0.75

Step-by-step explanation:

Given : The probability of choosing a black marble is P(Black)= 0.36.

The probability of choosing a black and then a white marble is P( Black and white) = 0.27.

Then by conditional probability ,

The probability of the second marble being white if the first marble chosen is black = P(\text{white }|\text{Black})=\dfrac{\text{P( Black and white)}}{\text{P(Black}}

=\dfrac{0.27}{0.36}=\dfrac{27}{36}=0.75

Therefore , the probability of the second marble being white if the first marble chosen is black = 0.75

The radius of a cylindrical construction pipe is 1.5 ft. If the pipe is 17 ft long, what is the volume?
Marta_Voda [28]

Answer:

120.105 square feet.

Step-by-step explanation:

Given that the radius of a cylindrical construction pipe is 1.5 ft, to determine its volume, given that the pipe is 17 ft long, the following calculation must be performed, knowing that the volume of a cylinder arises from multiplying the number pi by the radius at square of the cylinder, and that result by the height of it:

(3.14 x (1.5^2)) x 17 = X

(3.14 x 2.25) x 17 = X

7.065 x 17 = X

120.105 = X

Thus, the volume of the cylinder is 120.105 square feet.
