Answer:
0.245
Step-by-step explanation:
The population proportion refers to the proportion of the total population. In the scenario above, the population proportion is the proportion of all adult population in the United States who are obese. Therefore the population proportion for the scenario is (24.5 / 100) = 0.245; which is the proportion of all adults in the United States who are obese.

A player hits a second baseball. The second baseballs path is modeled by the function g (t) = -16(t-4)^2 + 256. Which baseball has a greater maximum height? Which baseball is in the air for the longest?
Answer:
1). Maximum height achieved by the baseball = 256 units
2). duration for which baseball is in the air = 8 seconds
Step-by-step explanation:
A player hits a second baseball. Path of the baseball is defined by the function g(t) = -16(t - 4)² + 256
By comparing this equation with the quadratic function,
f(x) = a(x - h)² + k
Here, (h, k) is the vertex of the given equation.
Vertex of the given equation → (4, 256)
Therefore, maximum height the baseball can each = 256 units
And time taken to reach the maximum height = 4 seconds
So the duration of time in which baseball is in the air = Time taken to reach the maximum height + Time taken to come down from maximum height
= 4 + 4
= 8 seconds
L U C K luck is parallelogram with ∠C=68° and ∠LUK=42° find: 1.
m∠ CUK 2. m∠ K
Answer:
1. m∠CUK = 70°
2. m∠K = 112°
Step-by-step explanation:
1. The given parameters of the parallelogram LUCK are;
∠C = 68°
∠LUK = 42°
From the diagram of parallelogram LUCK obtained from an online source, we have;
Given that LUCK = A parallelogram, we have;
The same side interior angles ∠C and ∠U are supplementary angles
Therefore;
∠C + ∠U = 180°
∠U = 180° - ∠ C
∴ ∠U = 180° - 68° = 112°
∠U = 112°
By angle addition property, ∠U = ∠LUK + ∠CUK
∴ m∠CUK = ∠U - ∠LUK
By plugging in the value of ∠LUK = 42°, and ∠U = 112°, we have;
m∠CUK = ∠U - ∠LUK = 112° - 42° = 70°
m∠CUK = 70°
2. By angle addition property, we have;
∠K = ∠LKU + ∠CKU
∠LKU and ∠CUK are alternate interior angles
∴ ∠LKU = ∠CUK = 70°
Similarly, ∠CKU and ∠LUK are alternate interior angles
∠CKU = ∠LUK = 42°
m∠K = ∠LKU + ∠CKU = 70° + 42° = 112°
m∠K = 112°.

The base of a rectangular prism has dimensions measuring 8 feet by 17 feet. If the volume of the prism is 1,632 cubic feet, find the height of the prism.
Answer:
the answer is 12
Step-by-step explanation:
I had this work sheat and got the answer from the teacher
For the volume of the prism is 1,632 cubic feet, the height of the prism is,
⇒ H = 12 feet
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
.
Given that;
The base of a rectangular prism has dimensions measuring 8 feet by 17 feet.
And, the volume of the prism is 1,632 cubic feet.
Now, We know that;
Volume of prism = B x H
Where, B is base area and H is height.
Hence, We get;
Volume of prism = B x H
1632 = 8 x 17 x H
1632 = 136 H
H =1632 / 136
H = 12 feet
Thus, For the volume of the prism is 1,632 cubic feet, the height of the prism is,
⇒ H = 12 feet

Solve for x
90°
\12x-22)
170°
Answer:
x = 6
Step-by-step explanation:
Using this theorem to get the other angles of the triangle.
Angle at the vertex is equal to half of the angle at the intercepted arc
For the arc with angle 170degrees
Angle at the vertex = 1/2 * 170
Angle at the vertex = 85 degrees
For the arc with angle 90degrees
Angle at the vertex = 1/2 * 90
Angle at the vertex = 45 degrees
Taking the sum of the 3 angles and equating to 180
85 + 45 + 12x - 22 = 180
130-22+12x = 180
12x = 180 - 108
12x = 72
x = 72/12
x = 6
Hence the value of x is 6

A rectangular prism and its dimensions are shown in the figure below. Study the figure below... 12 centimeters... 28 centimeters... 22 centimeters... Which of the following could be used to calculate the total surface area of the figure?
Answer:
Step-by-step explanation:
The surface area of the prism will be 2432 cm²
What is surface area?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Given that, a rectangular prism has dimensions 28 x 22 x 12, we need to find the surface area,
The surface area = 2[lh+wh+lw]
l = length, w = width and h = height
Therefore, the SA = 2[28×22+22×12+12×28]
= 2 × 1216
= 2432
Hence, the surface area of the prism will be 2432 cm²

Show the work/explain!
Answer:
3/50
Step-by-step explanation:
Slope m = y2-y1/x2-x1
From the coordinate
x1 = 2/5, y1 = 2/3, x2 = -4/9 and y2 = 3/5
Substitute;
m = (3/5 - 2/3)/-4/9-2/3
m = (9-10/15)/(-4-6/9)
m = -1/15/-10/9
m = -1/15 * -9/10
m = 9/150
m = 3/50
Hence the slope of the line passing through the points is 3/50

A science teacher collects 19 pints of lake water for a lab she is teaching. The lab requires each student to use 4 fluid ounces of lake water.
If 44 students are participating, how many pints of lake water will the teacher have left over?
There will be ________ pints of lake water left over.
Answer: 8 pints of lake water
Step-by-step explanation:
We should note that:
1 pint = 16 fluid ounces
Therefore, 19 pints will be converted to ounces which will be:
= 19 × 16
= 304 ounces
Since there are 44 students participating and each student uses 4 fluid ounces, the students will use:
= 44 × 4
= 176 fluid ounces
We then subtract from the total ounces to know the amount left. This will be:
= 304 - 176
= 128 fluid ounces
We then convert back to pints which I'll be:
= 128/16
= 8 pints
There'll be 8 pints of lake water left.
