How is the percentage of a value calculated?The percentage represents a value divided by 100. In this way, saying 25% of a value is the same as saying 25 out of 100, that is, 25 divided by 100. And to find the exact number of absentees in the event, just multiply the whole by the percentage
So in this case, we have the information that:
May: 223 Dinztop salesJune: 148 Dinztop sales.Using the percentage we have:
[tex]p=\frac{148}{223} = 0.6637[/tex]
This value in percentage that will be:
[tex]0.6637*100\%= 66.37\%[/tex]
Because of the same percent rate, the amoutns sold in June:
[tex]66.37\%*148=98[/tex]

What is the area of the figure? Use 3.14 for π. Round to the nearest hundredth if necessary.
Answer:
81.12 cm²
Step-by-step explanation:
The area for a semicircle can be figured with this formula: (πr²)/2. The triangle's area formula is bh/2.
(3.14 * 4²)/2 + (14 * 8)/2 (Work the operations in parentheses first.)
(3.14 * 16)/2 + 112/2
50.24/2 + 112/2 (Divide 50.24 by 2. Do the same for 112.)
25.12 + 56 (Add 25.12 & 56.)
81.12 cm²
The area of the figure is 81.12 cm².
What is the general equation of a sine function with an amplitude of 6, a period of StartFraction pi Over 4 EndFraction, and a horizontal shift of StartFraction pi Over 2 EndFraction?
y = sine (8 (x minus StartFraction pi Over 2 EndFraction))
y = 8 sine (4 (x minus StartFraction pi Over 2 EndFraction))
y = 6 sine (8 (x minus StartFraction pi Over 2 EndFraction))
y = 6 sine (8 x) + StartFraction pi Over 2 EndFraction
Answer:
C: [tex]y = 6 \sin (8(x-\frac{\pi}{2} ))[/tex]
Step-by-step explanation:
Amplitude is changed by multiplying the entire trig function by a number, by default the amplitude is 1, so multiplying by 6 is necessary; eliminate A and B
Horizontal shift is going through the x axis, so it must be subtracted from the x value. This is only seen in choice C of the remaining answers.
Calculating the period isn't necessary because we already found the right answer but in case you need it in the future; the period is by default 2pi, to get to pi/4, it had to be 8 times smaller, so multiplying x and translations on x by 8 will get you the correct period.
The General equation of a sine function is f(x) = 6·sin(8(x -π/2)).
What is Sine Function?The sine function can be defined as the ratio of the length of the opposite side to that of the hypotenuse in a right-angled triangle. The sine function is used to find the unknown angle or sides of a right triangle.
Here, Amplitude = 6, P=π/4, and S=π/2
A transformed sine function with amplitude A, period P, and horizontal shift S can be written as ...
f(x) = A · sin(2π/P(x -S))
f(x) = 6·sin(8(x -π/2))
The horizontal shift is equal to two full periods, so the shifted function is indistinguishable from the unshifted function.
Thus, the General equation of a sine function is f(x) = 6·sin(8(x -π/2)).

You have a jar of Marbles in front of you 2 are Cordovan, 9 are yellow, 3 are white and 7 are red. What is the probability, as a fraction of selecting a marble that is white or yellow, followed by a marble that is Cordovan?
Answer:
2/35
Step-by-step explanation:
Assuming that this is without replacement,
The total amount of marbles is 2+9+3+7, or 21.
9 are yellow, 3 are white. this makes 12.
The probability of selecting a white or yellow marble is 12/21.
Now without replacement (comment if it is with replacement.), there are 20 marbles left, and 2 are Cordovan. This means there is a 2/20 chance then of picking a Cordovan marble.
After multiplying the fractions we get
(12/21) * (2/20) = 2/35.
There is a 2/35 chance of selecting a yellow or white, then a cordovan marble.

Answer:
A) 26°
Step-by-step explanation:
The angle x decreases at a rate that is 12 times the rate of increase of angle y.
x = 360 -12y
We want x = 2y, so ...
2y = 360 -12y
14y = 360
y = 360/14 ≈ 25.71 ≈ 26
The integer angle closest to y is 26°.

Which box plot shows data that is skewed right?
Answer:
I think its a
Step-by-step explanation:
The box plot in option A is right-skewed or in other words positively skewed.
A box plot is a graphical representation of the distribution of a dataset, particularly picturizing its center, spread, and potential outliers. It is also used to find the skewness in the distribution.
It is also known as a box-and-whisker plot.
The given data points are 10, 20, 30, 40, 50, 60.
As the number of observations, n = 6, is even, the following formula will be used to find the median:
[tex]Med(X) = \dfrac{X_\frac{n}{2}+X_\frac{n}{2} _+_1 }{2}[/tex],
where X is the random variable such that X ∈ [10, 60].
[tex]X_\frac{n}{2} = X_\frac{6}{2} = X_3 = 30\\X_\frac{n}{2}_+_1 = X_\frac{6}{2}_+_1 =X_{3+1} = X_4 = 40[/tex]
[tex]Med(X) = \dfrac{30 + 40 }{2}[/tex]
[tex]= \dfrac{70}{2} \\= 35[/tex]
It is clear that the whiskers of the box plot in Figure A are shifted right to the median, 35.
Thus, the box plot in option A is right-skewed.

PLEASE HELP. the question is “the diameter of the semicircle below is 12 yards. find the area and perimeter” you don’t have to do both numbers just pls let me know what one you solve. you can even only do area. i just rlly need help.
Answer:
Area = 346.2yd²
Perimeter = 72.1yd
Step-by-step explanation:
AREA
Split it into three shapes: (1) the semi-circle, (2) the triangle, and (3) the rectangle. Find the area of each and then add them together for the area of the whole shape.
Area₁ = πr² = (6²)π = 36π = 113.1 yd²
Area₂ = (1/2)bh = (1/2)(11.3)(14) = 79.1 yd²
Area₃ = lw = (11)(14) = 154 yd²
154 + 79.1 + 113.1=346.2yd²
PERIMETER
The perimeter consists of the length of the curve on the semi-circle, the top , the right side, the bottom, and the slanted line.
length of the curve on the semi-circle = half the cicumference of circle with radius 6 = (2π(6))/2 = 6π = 18.8
the top = 22.3
the right side = 14
the bottom = 11
the slanted line = the hypotenuse of triangle(2) - the diameter of circle(1) = (√(11.3²+14²))-12= (√(323.69))-12=18-12=6
18.8+22.3+14+11+6=72.1yd

Answer:
Rate of change = -0.2
Step-by-step explanation:
Given:
(-3, 3.6) and (5, 2)
Required:
Rate of change
Solution:
Formula for rate of change = change in y/change in x = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let,
(-3, 3.6) = (x_1, y_1)
