Answer:
Step-by-step explanation:M+F=39
M+F=39
F=M-9
Substitute
M + M - 9 = 39
2M = 48
M=48/2
M=24
24+F=39
F=39-24=15
F=15, M=24
Answer:
15 females
24 males
Step-by-step explanation:
Given;
39 students total
9 more male student than female
1. Set up an equation
Call the number of female student "x"
Since there are 9 more male students, the number of male students is (x + 9),
Assuming those are the only genders in the class, the equation formed is;
females + males = total
x + x + 9 = 39
2. Solve,
Simplify and inverse operations;
x + x + 9 = 39
2x + 9 = 39
2x = 30
x = 15
15 females
24 males

A circular flower garden has a diameter of 16 ft. A square pond is placed in the center that measures 5 ft on each side. About how much area of the garden remains for the flower garden
Answer:
779.352 ft^2
Step-by-step explanation:
Given data
Diameter of circular garden= 16ft
Radius of garden= 16/2= 8ft
Length of side of square pond= 5ft
Area of circular garden= πr^2
A=3.142*16^2
A= 3.142*256
A=804.352 ft^2
Area of square pond
A= L^2
A= 5^2
A= 25ft
Hence the area that remains
=Area of circular garden- Area of square pond
=804.352- 25
= 779.352 ft^2

(a) Consider the pulse rates of two patients in a hospital for ten different days:
Patient A: 17 16 70 69 70
75 78 70 71
69
Patient B: 59
92
60
80 71
65

88
95 70
Find the mean pulse rate for each patient and the corresponding range.
Answer:
1a. Mean pulse rate for A = 60.5
1b. Range for A = 62
2a. Mean pulse rate for B = 73
2b. Range for B = 45
Step-by-step explanation:
1a. Determination of the mean pulse for patient A.
Data => 17, 16, 70, 69, 70, 75, 78, 70, 71, 69
Mean =?
The mean pulse rate for patient A can be obtained as follow:
Summation of data = 17 + 16 + 70 + 69 + 70 + 75 + 78 + 70 + 71 + 69
Summation of data = 605
Number of data = 10
Mean = summation of data / number of data
Mean = 605 / 10
Mean pulse rate for A = 60.5
1b. Determination of the range for patient A
Data => 17, 16, 70, 69, 70, 75, 78, 70, 71, 69
Range =?
Range = Highest – Lowest
Highest = 78
Lowest = 16
Range = Highest – Lowest
Range = 78 – 16
Range for A = 62
2a. Determination of the mean pulse for patient A.
Data => 59, 92, 60, 80, 71, 65, 50, 88, 95, 70
Mean =?
The mean pulse rate for patient B can be obtained as follow:
Summation of data = 59 + 92 + 60 + 80 + 71 + 65 + 50 + 88 + 95 + 70
Summation of data = 730
Number of data = 10
Mean = summation of data / number of data
Mean = 730 / 10
Mean pulse rate for B = 73
2b. Determination of the mean pulse for patient B.
Data => 59, 92, 60, 80, 71, 65, 50, 88, 95, 70
Range =?
Range = Highest – Lowest
Highest = 95
Lowest = 50
Range = Highest – Lowest
Range = 95 – 50
Range for B = 45

4 7 /32
Step-by-step explanation:
135 : 32 = 4 ( 7)
Kết quả:
135 /32
= 4 7 /32
Answer:
[tex]4\frac{7}{32}[/tex]
Step-by-step explanation:
Given the mixed numbers:
[tex]1\frac{1}{4}[/tex],[tex]1\frac{1}{2}[/tex],[tex]2\frac{1}{4}[/tex]
First, we need to convert them into improper fractions of the denominator of 4.
1 1/4 = 5/4
1 2/4 = 6/4
2 1/4 = 9/4
So we multiply 1 1/4 x 1 2/4 x 2 1/4 which gets us 4 7/32

What is the value of h?
Give your answer correct to 1 decimal place.
The measure of value of h from the trigonometric relations is h = 11.4 cm
What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the triangle be represented as ΔABC
Now , the value of sides of the right triangle ABC is
AB = 7 cm
AC = h cm
The angle ∠ACB = 38°
Now , from the trigonometric relations , we know
sin θ = opposite / hypotenuse
Substituting the values in the equation , we get
sin θ = 7 / h
sin 38° = 7 / h
Multiply by h on both sides of the equation , we get
h ( sin 38° ) = 7
Divide by sin 38° on both sides , we get
h = 7 / sin 38°
Substitute the value of sin 38° = 0.6157
h = 7 / 0.6157
h = 11.369 cm
Rounding the value to 1 decimal place , we get
The value of h = 11.4 cm
Hence , The measure of value of h is h = 11.4 cm

Suppose you asked 100 commuters how much they spend each year and obtained a mean of $167 spent on transportation and a standard deviation of $40. Using the 2 SE rule of thumb, calculate a 95% confidence interval for the mean and select the values that come closest to those that would fill the spaces in the following interpretation: we can be 95% confident that the mean amount of money spent on transportation lies between _____ and _____ .
Answer:
The correct answer is "$159 and $175".
Step-by-step explanation:
The give values are:
Mean,
= $167
Standard deviation,
[tex]\sigma[/tex] = $40
Number of commuters,
n = 100
Now,
⇒ [tex]SE=\frac{\sigma}{\sqrt{n} }[/tex]
On putting the given values, we get
⇒ [tex]=\frac{40}{\sqrt{100} }[/tex]
⇒ [tex]=\frac{40}{10}[/tex]
⇒ [tex]=4[/tex]
By using the 2 SE rule of thumb, we get
= [tex]$(167 - 2\times 4)[/tex]
= [tex]167-8[/tex]
= [tex]159[/tex] ($)
Or,
= [tex](167 + 2\times 4)[/tex]
= [tex]167+8[/tex]
= [tex]175[/tex] ($)

Find the equation of the line with slope =8 and passing through (3,21) write your equation in the form y=Mx+b
Answer: y = 8x -3
Step-by-step explanation:
we know the slope already which is 8.
so the equation is: y = 8x + b
subsutite the x and y to get the value of b
21 = 8(3) + b
21 = 24 + b
b = -3
So the equation is: y = 8x -3
The equation with the given condition is y=8x-3.
Given that, the slope of an equation (m)=8 which is passing through (3, 21).
We need to find an equation for the given condition.
What is slope intercept form?The slope-intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis). The equation of the line is the equation that is satisfied by each point that lies on that line.
Now, put m=8 and the coordinates (3, 21) in y=mx+b and simplify.
That is, 21=8×3+b
⇒21=24+b
⇒b=-3
So, the equation is y=8x-3
Therefore, the equation with the given condition is y=8x-3.

Answer:
9
Step-by-step explanation:
The number of marble left if Keith has a package of 75 marbles, He gave an equal number of marbles to each of his 8 friends, is 3.
What is division?Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups.
When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers. For instance, 4 2 = 2. As a multiplication fact, this can be expressed as 2 + 2 = 4.
Given:
Keith has a package of 75 marbles, He gave an equal number of marbles to each of his 8 friends,
Calculate the number of marble left as shown below,
The number of marble left = Reminder of (total number of marble / 8)
The number of marble left = Reminder of(75 / 8)
The number of marble left = 3
Thus, the number of marble left is 3.

Answer:
110 degrees
Step-by-step explanation:
Because these angles are vertical, 5x+15=8x-42. thus, 15=3x-42, 3x=57, and x=19. 5x+15=5(19) +15=110. So, m<CDE=110 degrees.
Answer:
110°
Step-by-step explanation:
Since CDE and FDG are vertical, they are congruent, so:
5x + 15 = 8x - 42
Solve the equation for x
57 = 3x
19 = x
Then solve for one of the angles (I chose CDE but FDG would also work)
5(19)+15
95 + 15
110
