Below, the two-way table is given for a class of students.
^^^^^ (photo attached)
If a student is selected at random, find the
probability the student is a senior given that it's
female. Round to the nearest whole percent.
[?]%
Answer:
Solution given:
total female [T]=3+4+6+3=16
n[senior female]=3.
probability the student is a senior given that it's
female:[tex] \frac{n[senior female]}{total [T]} [/tex]
:[tex] \frac{3}{16} [/tex]
:[tex] \frac{3}{16} [/tex] is a probability.
Now percentage::[tex] \frac{3}{16}*100% [/tex]=18.75=19%
Answer:
18.75%. Rounding up: 19%
Step-by-step explanation:
From the table : Total Females = 3+4+6+3 = 16
Number of female seniors = 3
If a student is selected at random find the probability the student is a senior given that it's a female:
P(Female | senior) = number of female seniors / total female = 3/16 = 0.1875
In percent, 3/16 * 100 = 0.1875 * 100 = 18.75%
the probability the student is a senior given that it's a female. = 18.75%, which round to nearest whole percent is 19%.

Answer:
A = 53° (Rounded to the nearest whole number)
Step-by-step explanation:
Since the angle needs to be found out and it's adjacent as well as hypotenuse is given we will used the Cosine ratio;
Cos(A) = [tex]\frac{26}{43}[/tex]
A = Cos⁻¹ ([tex]\frac{26}{43}[/tex])
A = 52.79 or 53

What is the center and radius of the following
circle:
(x +4)2 + (-2) = 4?
Answer:
x = -1
Step-by-step explanation:
Answer:
That is not a circle; it has no y term
My guess:
center = (h, k) = (-4, 2)
r = √4 = 2
Step-by-step explanation:
If I had to guess what you intended:
(x + 4)² + (y - 2)² = 4
The standard equation for a circle is
(x - h)² + (y - k)² = r²
(h, k) is the center and r is the radius
center = (h, k) = (-4, 2)
r = √4 = 2

Find the mean, median, mode, and range for the following numbers.
62,58,92,16,24
HELP ME PLS
Answer:
Mean: 50.4
Median: 58
Mode: None
Range: 76
Step-by-step explanation:
The mean is all the numbers added together and then divided by 5.
(62 + 58 + 92 + 16 + 24) ÷ 5 = 50.4
The median is the number in the middle. First, arrange the numbers from least to greatest and then pick the one in the middle
16, 24, 58, 62, 92
The mode is the number that appears the most. There is no mode in this data set because every number appears once.
The range is the biggest number subtract by the smallest number.
92 - 16 = 76

Answer:
Step-by-step explanation:
How many times must you roll an ordinary 6-sided dice for the probability of getting at least one multiple of 3 more than 0.7
Given a six sided die : (1, 2, 3, 4, 5, 6)
Multiple of 3 = (3, 6) = 2
Getting a multiple of 3 on a single roll :
P(multiple of 3) = 2 / 6 = 1/3
The verticles of a polygon p(0,4), q(5,4), r(5.-3) and s(0,-3). What are the perimeters of the polygon
Answer:
Following are the responses to the given question:
Perimeter of polygon:
[tex]PQ = 5\\\\RS = 5\\\\PR = QS=\sqrt{74} = 8.60\\\\QR = 7[/tex]
Step-by-step explanation:
In this question we calculate the perimeter of a polygon which can be defined as follows:
Using formula:
[tex]d = \sqrt{(x _2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
When vertices are:
[tex]P ( 0 , 4) \\\\Q(5 , 4)[/tex]
[tex]x_1 = 0\\\\y_1 = 4\\\\x_2 = 5\\\\y_2 = 4\\\\PQ = \sqrt{( 5 - 0)^2 + ( 4 - 4)^2}\\\\= \sqrt{5^2 + 0^2}\\\\= \sqrt{25}\\\\= 5[/tex]
[tex]R( 5 , -3) and S ( 0 , -3)x_1 = 5y_1 = -3x_2 = 0\\y_2 = -3\\RS = \sqrt{ ( 0 - 5)^2 + ( -3 - (-3))^2}\\= \sqrt{( -5)^2 + ( -3 + 3)^2}\\= \sqrt{ 25 + 0}\\= \sqrt{25}\\= 5\\P( 0 , 4)\ and\ R (5 , -3)\\x_1 = 0\\y_1 = 4\\x_2 = 5\\y_2 = -3\\PR = \sqrt{( 5 - 0)^2 + ( -3 - 4)^2}\\= \sqrt{5^2 + (-7)^2}\\= \sqrt{ 25 + 49}\\= \sqrt{74}\\= 8.60\\[/tex]
[tex]Q ( 5 , 4) \ and \ S(0 ,-3)\\x_1 = 5\\y_1 = 4\\x_2 = 0\\y_2 = -3\\QS =\sqrt{ ( 0 - 5)^2 + ( -3 - 4)^2}\\= \sqrt{-5^2 + -7^2}\\= \sqrt{25 + 49}\\= \sqrt{74}\\= 8.60[/tex]
[tex]Q( 5,4\ and\ R(5 , -3)\\x_1 = 5\\y_1 = 4\\x_2 = 5\\y_2 = -3\\QR = \sqrt{(5 - 5)^2 + ( -3 - 4)^2}\\= \sqrt{0^2 + (-7)^2}\\= \sqrt{0 + 49}\\= \sqrt{49}\\= 7\\[/tex]

A fire department's ladder is 110 feet long. A firefighter is trying to reach the top of a 100 foot building by leaning the ladder against the building. What is the angle of elevation for the rescue ladder?
Answer:
sin-¹(10/11)
Step-by-step explanation:
The height of the building is 100 ft and the ladder is 110ft long .We can imagine this situation as a right angled ∆. For figure refer to the attachment .
We can use ratio sine here. Let the angle of elevation be theta.In ∆ ABC :-
=> sinθ = p/h
=> sinθ = 100ft / 110 ft
=> sinθ = 10/11
=> θ = sin -¹ ( 10/11) .
Hence the angle of elevation is sin -¹ ( 10/11).(answer quickly please)

Answer:
181 mi^2
Step-by-step explanation:
Dimensions of large rectangle, on the left, are 6 mi by 8 m; area is 48 m^2;
Dimensions of small rectangle, in the middle of the diagram, are 4 mi by 5 mi, or 20 mi^2; area is 20 mi^2.
Dimensions of circle: r = 12 mi; area of quarter circle is (1/4)(3.14)(12 mi)^2, or 113 mi^2.
Total area is 113 mi^2 + 20 mi^2 + 48 mi^2, or 181 mi^2
Answer:
Step-by-step explanation:
So first off. lets take chunks of this shape. We have a 6x8 rectangle, a 4x5 rectangle, and a 1/4 circle with a radius of 12.
The area of a rectnagle is just length x width.
So lets plug in our values for our two ractnagles, and see what we get:
6*8
=
48
So our first rectangle has a area of 48
Next we have:
4*5
=
20
So our second rectangle has an area of 20.
Add these otgether you get 68.
Finally we have our 1/4 circle. To solve this, find the area of the full circle and divide by 4.
We already know the radius, which is 12, and the formula for area of a circle is:
a=πr^2
Plug in 12:
a=π12^2
=
a=π144
dividing by four for the 1/4circle:
a=π36
So this means your answer is either:
68 +36π
Or:
181.097(solving pi*36)
Either of these work, if the problem allows pi, then use the first one, If not, use the bottom one.
Hope this helps!
I really need helppppp
Answer:
The correct answer is C.
Step-by-step explanation:
In the equation of a circle, if the variable [tex]x[/tex] and [tex]y[/tex] are added or subtracted by any number before being squared, the entire circle with be translated in the opposite amount that was added or subtracted to the circle. For example, [tex](x-8)^2 + (y-8)^2[/tex] shifts the center 8 to the right and up of the origin, [tex](x+1)^2+(y+4)^2[/tex] shifts the center 1 to the left and 4 down of the origin. Since the circle represented in the graph is centered directly on the origin, that means the equation will have [tex]x^2+y^2[/tex], which helps you eliminate choices A and C. For the equation of a circle, the radius is the value of the constant on the right side of the equal sign taken to its square root. Since the radius of this circle is 8, that means the constant at the right side of the circle would be 64 or [tex]8^2[/tex], so the correct answer would be choice C: [tex]x^2+y^2=8^2[/tex].
