The age of trees in a forest is known to be approximately normal with an average age of 40 years and a standard deviation of 10 years. What is the standardized score for a tree that is 34 years old?

Answer:

figure 1 is 8.5 units^2 and figure 2 is 3 units^2 and the average are is 5.25 units^2

The overestimated area, the underestimated area, and the average area will be 8.5 units², 3 units², and 2.75 units², respectively.

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

Since the area is covered with either a square or a triangle. Therefore, we can write the area of this two as,

Area of a square = 1 unit × 1 unit = 1 unit²

Area of triangle = 0.5 × 1 unit × 1 unit = 0.5 units²

The overestimated area, the number of square and triangles are,

Number of square = 6

Number of triangle = 5

Total overestimated area = (6×1unit²) + (5×0.5unit²) = 8.5 unit²

The under estimated area, the number of square and triangles are,

Number of square = 2

Number of triangle = 2

Total Underestimated area = (2×1unit²) + (2×0.5unit²) = 3 unit²

Furthermore, the average area is,

Average area = (Total overestimated area - Total Underestimated area)/2

                       = (8.5 units² - 3 units²) / 2

                       = 5.5  units² / 2

                       = 2.75 units²

Hence, the overestimated area, the underestimated area, and the average area will be 8.5 units², 3 units², and 2.75 units², respectively.

Answer:

Answer:

C. 48 lizards and 24 frogs

Step-by-step explanation:

Let F = number of frog lures, and let L = number of lizard lures.

Marion bought 14 packages of plastic frog and lizard fishing lures.

She bought frog lures in packages of 4 and lizard lures in packages of 6 for a total of 72 lures.

F + L = 72

F/4 + L/6 = 14

12 * F/4 + 12 * L/6 = 12 * 14

         3F + 2L = 168

(+)      -3F - 3L = -216

------------------------------

                   -L = -48

L = 48

F + L = 72

F + 48 = 72

F = 24

Answer:

We can assume that the number of 3-pointers he made in his last game was 10 3-pointers

Step-by-step explanation:

In the question, we have;

The 3-point percentage rate for Stephen Curry = 43.5 successful made out of 100 attempts

The 3-point percentage rate for LeBron James = 34.5 successful made out of 100 attempts

The 3-point percentage rate for James Harden = 36.4 successful made out of 100 attempts

Whereby Steph Curry attempted 25 3-pointers in the last game he played and where 'x' represents the number of 3-pointers we can assume he made, we have;

x = 43.5% of 25

[tex]\therefore x = \dfrac{43.5}{100} \times 25 = 10.875[/tex]

Given that 'x' can only have whole number values, and the 3-point percentage is calculated using a larger number of attempts than 25, we can assume he made 10 3-pointers in his last game

The 3-pointers the Stephen Curry made in last game is 10, if he attempted 25 3-pointers.

It is given that the four players from the NBA and their career 3-point percentages are listed below in the table

It is required to find the number of 3 pointers he made if Steph Curry attempted 25 3-pointers in his last game.

It is defined as the ratio or number presented as fraction of 100, the symbol of percentage is %.

We have in the question that:

The 3-point percentage rate for Stephen Curry is 43.5% out of 100 attempts.

We know that,

[tex]\rm 3-point \ percentage = \frac{Number \ of \ 3-pointers}{Number \ of \ 3-pointers \ attempts} \\[/tex]

3 - point percentage for Stephen Curry = 43.5%

Number of 3-pointers he attempts = 25

Putting these values in the above formula, we get:

[tex]\rm 43.5 \%=\frac{Number \ of \ 3-pointers}{25} \\\\\rm \frac{43.5}{100} \times25 = Number \ of \ 3-pointers\\\\\rm Or \ number \ of \ 3-pointers = 10.875[/tex]

But the number of 3-pointers can be a whole number, so we can assume that the 3-pointers is 10.

Thus, the 3-pointers the Stephen Curry made in last game is 10, if he attempted 25 3-pointers.

Step-by-step explanation:

Answer:

The total surface area of the figure is approximately 10.2 m²

Step-by-step explanation:

The dimensions of the solid are;

The shape of the solid = An half cylinder

The diameter of the cylinder, D = 1.6 m

The length of the cylinder, l = 2 m

The surface area of the curved part of the solid = π × D × l ÷ 2

Therefore;

The surface area of the curved part of the solid = π × (1.6 m) × 2 m/2 ≈ 5.03 m²

The area of the curved surface, V = 5.03 m²

The area of the rectangular top, A = 1.6 m × 2 m = 3.2 m²

The area surface of the semi-circular sides of the figure = 2 × π·D²/4 ÷ 2

Therefore;

The area surface of the semi-circular sides of the figure = 2 ×π × (1.6 m)²/4 ÷ 2 ≈ 2.01 m²

The total surface area of the figure, A = 5.03 m² + 3.2 m² + 2.01 m² = 10.24 m²

The total surface area of the figure ≈ 10.2 m² (rounding to 1 decimal place)

Since 2 inches = 6 ft and length of room in the place = 7 inches,

(2x3.5) inches = 6x3.5 ft

7 inches = 21ft

Actual Length of Room = 21 ft.

Width of Room in plane = 3 inches

(2x1.5) inches = 6 x 1.5 ft

= 9 ft

Actual Length of Rook = 9 ft.

Actual Area of Room = Actual Length of Room x Actual Width of Room = 21 x 9 = 189 ft^2
