A national park has two types of bears: Grizzly bears and black bears. A sciantist has reported 9 out of 12 bears she tagged are black bears. Show a model that compares the number of black bears tagged to the number of grizzly bear?
Answer:
Z = 0.75x + 0.25y
Step-by-step explanation:
Two bear types are identified :
Black bears and Grizzly bears
9 out of 12 = black bears ; Hence, 3 are grizzled
For the model:
For a bear population of Number x
Total bear population = black bear, x + grizzled bear, y
Proportion of black bear = 9/ 12 = 0.75
Grizzled bear = 1 - 0.75 = 0.25
Total bear population , Z= 0.75x + 0.25y
Hence,
Z = 0.75x + 0.25y

Devin bought a new car
for $19,024 and it was
20% off. Determine the
original price of the car.
Answer:
$23780
Step-by-step explanation:
Given data
Let the original price be x
discount= 20%
price= $19,024
so that
20/100*x=x-19,024
0.2x= x-19,024
19,024=x-0.2x
19,024=0.8x
x= 19,024/0.8
x=23780
Hence the original price is $23780

write an equation of the given line that passes through the given point and has the given slope m
(5,1);m=2
Answer:
y = 2x - 9
Step-by-step explanation:
Use slope intercept form, y = mx + b
Plug in the slope, x, and y, then solve for b:
y = mx + b
1 = 2(5) + b
1 = 10 + b
-9 = b
Then, plug in b and the slope into y = mx + b
y = mx + b
y = 2x - 9
So, the equation of the line is y = 2x - 9
Answer:
Step-by-step explanation:
y=mx+b, m=2
y=2x+b, using point (5,1)
1=2(5)+b
b=-9
y=2x-9
Find the volume of triangular prism with the following dimensions. Round to the nearest whole number.
Triangle base= 7 ft.
triangle height= 4 ft
prism height: 8.5 ft
Answer:
124.0 ft^2
Step-by-step explanation:
let b = base of triangle = 7ft
h = height of triangle = 4ft
and
l = height of prism. = 8.5ft
We know,
volume of prism = area of triangular face of prizm × height of prizm
= 1/2 × b × h × l
= 1/2 × 7 × 4 × 8.5
= 7 × 2 × 8.5
= 14 × 8.5
= 124.0 ft^2Find the area of the shape below, giving your answer to 1 decimal place.
10 cm
15 cm
Answer:
≈ 189.3 cm²
Step-by-step explanation:
The shape is composed of a rectangle and a semicircle, then
area of rectangle = 15 × 10 = 150 cm²
The semicircle has a diameter of 10 cm , so radius = 10 ÷ 2 = 5 cm
area of semicircle = [tex]\frac{1}{2}[/tex] πr² = 0.5 × π × 5² = 12.5π cm²
area of shape = 150 + 12.5π ≈ 189.3 cm² ( to 1 dec. place )

Suppose you have a right triangle area marked in the ground with a base (8-h) meters long and a height h meters long. the hypotenuse is 6 meters long.
part a: what is the length of the height of the right triangle
Answer:
5.415m and 2.585m long
Step-by-step explanation:
For a right triangle
hyp^2 = opp^2 + adj^2 (Pythagoras theorem)
Given
hypotenuse = 6m
height(opposite) = h meters
Adjacent = (8-h)m
Substitute into the expression above;
6² = h²+(8-h)²
36 = h²+64-16h+h²
36 = 2h²-16h+64
2h²-16h+64-36 = 0
2h²-16h+28= 0
Divide through by 2
h²-8h+14 = 0
Using the general formula
h = 8±√8²-4(14)/2
h = 8±√64-56/2
h = 8±√8/2
h = 8±2.83/2
h = 8+2.83/2 and 8-2.83/2
h = 10.83/2 and 5.17/2
h = 5.415 and 2.585
hence the length of the height of the right triangle are 5.415m and 2.585m long
Mary and Julie both have a goal of raising $1000 for charity. Mary raises $12 every 4 days. Julie raises $19 every 6 days.
Will Mary or Julie reach her goal first? Explain.
Answer:
Mary would have a rise of 12 and a run of 4, making her slope, or rate of change, $3 a day. Julie would have a rise of 19 and a slope of 6, making her slope, or rate of change, $3.17 a day. Since Julie is raising money at a faster rate, she would get to the goal of $1000 first.

Together, teammates Pedro and Ricky got 2680 base hits last season. Pedro had 276 more hits than Ricky. How many hits did each player have?
Answer:
Ricky it is 1,202
And for Pedro = 1,202 + 276 = 1,478
Step-by-step explanation:
The computation is shown below:
Let us assume the ricky be x
So pedro be x + 276
Now the equation is
x + x + 276 = 2680
2x + 276 = 2680
2x = 2680 - 276
2x = 2404
x = 1,202
For Ricky it is 1,202
And for Pedro = 1,202 + 276 = 1,478

Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures televisions can be modeled by the polynomial 3x2 + 180x. The cost, in dollars, of producing the televisions can be modeled by 3x2 – 160x + 300. The variable x is the number of televisions sold.
If 150 televisions are sold, what is the profit?
$2,700
$6,000
$50,700
$51,300
Answer: $50,700 is the profit
If 150 televisions are sold, the profit is $50,700.
What is profit?
Profit is the total revenue less the total cost.
Profit = total revenue - total cost
What is profit?Profit = (3x^2 + 180x) - (3x2 – 160x + 300)
Profit = (3 x 150^2 + 180 x 150) - (3 x 150^2 - 160x 150 + 300)
27,000 + 24,000 - 300
Profit = $50,700
