the standard height from the floor to the bull's-eye at which a standard dartboard is hung is 5 feet 8 inches. a standard dartboard is 18 inches in diameter. suppose a standard dartboard is hung at standard height so that the bull's-eye is 12 feet from a wall to its left. brian throws a dart at the dartboard that lands at a point 11.5 feet from the left wall and 5 feet above the floor. does brian's dart land on the dartboard? drag the choices into the boxes to correctly complete the statements.
The question is an illustration of equation of circles.
The equation of the dartboard circle is: [tex](x-12)^{2}+(y-\frac{17}{3}) ^{2} =\frac{9}{16}[/tex]
Brian's dart lands on the dartboard because D = 11.5 feet , 5 feet is within the circumference of the dartboard.
Given that,
h = 5 feet 8 inches ---- the height at which the dartboard was hung
d = 18 inches in diameter ---- the diameter of the dartboard
B = 12 feet --- the bull's eye
D = 11.5 feet , 5 feet --- Brian's dart
Equation of the circle
First, we convert all units to feet
This is done by dividing inches units by 12
h = 5 feet 8 inches
h = 5 ft + 8/12 ft
h = 5 ft + 2/3 ft
Take LCM
h = [tex]\frac{15+2}{3}[/tex] ft
h = [tex]\frac{17}{3}[/tex] ft
d = 18 inches
d = [tex]\frac{18}{12}[/tex] ft
d = [tex]\frac{3}{2}[/tex] ft
Divide by 2 to calculate radius
r = [tex]\frac{3}{2*2}[/tex] ft
r = [tex]\frac{3}{4}[/tex] ft
To find the equation of a circle when you know the radius and centre, use the formula as [tex](x-a)^{2} +(y-b)^{2} =r^{2}[/tex] , where represents the centre of the circle, and is the radius.
The equation of the circle is represented as:
[tex](x-a)^{2} +(y-b)^{2} =r^{2}[/tex]
In this case:
a = B = 12 feet -- the distance between the bull's eye and the wall
b = h = [tex]\frac{17}{3}[/tex] ft ---- the height at which the dartboard was hung
So, we have:
[tex](x-a)^{2} +(y-b)^{2} =r^{2}[/tex]
[tex](x-12)^{2} +(y-\frac{17}{3}) ^{2} = (\frac{3}{4}) ^{2}[/tex]
Evaluate the exponents
[tex](x-12)^{2}+(y-\frac{17}{3}) ^{2} =\frac{9}{16}[/tex]
Hence, the equation of the circle is:
[tex](x-12)^{2}+(y-\frac{17}{3}) ^{2} =\frac{9}{16}[/tex]
Does Brian’s dart land on the dartboard?
Yes her dart lands on the dartboard because
D = 11.5 feet , 5 feet is within the circumference of the dartboard
Therefore,
The question is an illustration of equation of circles.
The equation of the dartboard circle is: [tex](x-12)^{2}+(y-\frac{17}{3}) ^{2} =\frac{9}{16}[/tex]
Brian's dart lands on the dartboard because D = 11.5 feet , 5 feet is within the circumference of the dartboard.

Mean 'μ' = np
= 58 × 0.94
= 54.52
Standard deviation 'σ' = √ np (1 - p)
= √ 58 × 0.94 × 0.06
= √3.2712
= 1.808
Variance 'σ²' = np( 1 - p )

(1 point)
The values of x and w on the triangle are given as follows:
w = 14.4, x = 11.2.
How to obtain the values of x and w?The values of x and w are obtained applying the trigonometric ratios, as the triangle is a right triangle.
The three trigonometric ratios are given as follows:
Sine of angle = length of opposite side divided by the length of the hypotenuse.Cosine of angle = length of adjacent side divided by the length of the hypotenuse.Tangent of angle = length of opposite side divided by the length of the opposite side.For the angle of 48º, we have that:
The adjacent side is w.The opposite side is of 16.Hence:
tan(48º) = 16/w
w = 16/tan(48º)
w = 14.4.
For the angle of 32º, we have that:
The adjacent side is 14.4 + x.The opposite side is of 16.Hence:
tan(32º) = 16/(14.4 + x)
tan(32º)(14.4 + x) = 16
x = (16 - 14.4tan(32º))/tan(32º)
x = 11.2.

Which of the following choices correctly names the figure below?
the capacity of an elevator is either 20 children or 15 adults. if 17 children are currently in the elevator, how many adults can still get in?
Two more adults can board the elevator if there are 17 children present inside.
Explain the concept of capacity of an elevator?The point when 20 children or 15 adults can enter an elevator is considered the elevator's capacity. The number of adults who can still enter the elevator when there are 17 children inside must be determined.A linear equation can be created to resolve the aforementioned issue.The number of adults who can still enter will be determined by the linear equation solution.
let
c is equal to a child's weight.a is equal to 1 adult's weight.20c = 15a ; 5 divided by both sides
4c = 3a
Another 3 kids can enter the elevator if there are already 17 in it.
The fact that;
3c = 9/4 a
3c = 9/4 a
3c = 2.25 a
3c = 2 a (no fraction)
Thus, two more adults can board the elevator if there are 17 children present inside.

An investor invested a total of $2900in two mutual funds. One fund earned a 8% profit while the other earned a 6% profit. If the investor's total profit was $194, how much was invested in each mutual fund?
The amount invested at 8% and 6% is 1000 and 1900 respectively.
What is the percentage?The percentage is a ratio that can be expressed as a fraction of 100.
Given that, The person invested $2900 in two mutual funds and the total profit is $194.
Let the amount invested at 8% is x, then the amount invested at 6% is:
2900-x
Since the total profit is $194, it follows:
8% of x + 6% of (2900 - x) = 194
8x/100 + 6(2900 - x)/100 = 194
8x + 17400 - 6x = 19400
2x = 19400 - 17400
2x = 2000
x = 1000
The amount invested at 6% is:
2900 - 1000
