Given that the mathematics score of a subject is between 600 and 690, what is the probability that the subject is male?
Answer: The number of subjects with a mathematics score in the range of 600 to 690 is 296,518.
The number of males with a mathematics score in the range of 600 to 690 is 162,564.
The probability of a subject being male, given that he has a mathematics score between 600 and 690, is:= [tex]\frac{162,564}{296,518} = 0..5482= 54.82 percent[/tex]
Step-by-step explanation:
Find the lateral area of a waffle cone with a diameter of 4.6 in. and a slant height of 7.9 in. Give your answer in terms of ℼ .
Answer:
18.17 × pi in²
Step-by-step explanation:
there are many seemingly different formulas out there for this, but they are actually all the same and differ only by what values of the cone we know at the beginning (and the custodian values are converted into the values we need for the calculation).
do we know the base area and the height of the cone, or the radius and the height, or the base area and the slant height (the length of the "mantle" straight from the bottom to the top), ... ?
well, here we know the diameter (this means it is 2 times the radius) and the slant height.
this is one of the easiest exercises.
the formula for this case is
LA = pi × radius × slant height = pi × (4.6 / 2) × 7.9 =
= pi × 2.3 × 7.9 = 18.17 × pi in²
2 Luna is 5 feet tall. How tall is she in centimeters? There are about 2.5 centimeters in
an inch.
Answer:
Luna is 150 centimeters tall
Step-by-step explanation:
Step 1: Determine the height in inches
5 feet * (12 inches / 1 feet)
60 inches
Step 2: Convert to centimeters
60 inches * (2.5 centimeters / 1 inches)
150 centimeters
Answer: Luna is 150 centimeters tall
Which function has the greatest y-intercept?
Answer:
f(x)
Step-by-step explanation:
Because f(x) = 4x + 5
Answer:
f(x)
Step-by-step explanation:
g(x) intercept Is shown to be 2
f(x) if u sub 0 into x to find the y intercept gives you 5
h(x) I you sub 0 into the equation in place of x to find the y intercept it gives you -1.84
and if you look at all ghe y intersect values f(x) is the greatest
if the vertex of an angle is on the edge of a circle
Answer:
When we say an angle is on a circle, we mean the vertex is on the edge of the circle. One type of angle on a circle is the inscribed angle (see Inscribed Angles in Circles). Another type of angle on a circle is one formed by a tangent and a chord.
1⁄5 × 4⁄7 × 3⁄4=?
I will give brainliest if you are correct
Answer:
[tex]\frac{3}{35}[/tex]
Start with 1/5 × 4/7[tex]\frac{1}{5} *\frac{4}{7} = \frac{1 * 4}{5 * 7} = \frac{4}{35}[/tex]
Preserve [tex]\frac{4}{35}[/tex] as x, it will be of good use in just a moment.[tex]\frac{4}{35} = x[/tex]
Multiply x([tex]\frac{4}{35}[/tex]) by [tex]\frac{3}{4}[/tex][tex]x * \frac{3}{4}[/tex]
To do this, you have to substitute the numerator(4) as x, and the denominator(35) as y.[tex]\frac{x(4) * 3}{y(35) * 4} = \frac{12}{140}[/tex]
Simplify using the LCD Least Common Denominator.[tex]\frac{12 / 4}{140 / 4} = \frac{3}{35}[/tex]

And with that information, your final answer is [tex]\frac{3}{35}[/tex]

The figure shows a carpeted room. How many square feet of the room are carpeted?
A polygon that is a part of a rectangle is shown with perpendicular sides. The top is labeled 6 feet. The side on the left is labeled 8 feet. The base is labeled 2 feet, and the side adjacent to it on the right is labeled 3 feet
24 square feet
28 square feet
34 square feet
36 square feet
Answer:
36 square feet
Step-by-step explanation:
Check the attachment for the missing sides.
1) We calculate the missing sides by subtracting one of the similar sides with the longest one possible. In this case, 6 - 2 = 4 and 8 - 3 = 5.
2) Strikethrough the compound shape, creating two shapes; then, label them. Check the diagram attached.
3) Now, let's find the area of each of the squares; and then, add them.
Shape A:
= 4 × 5
= 20
Shape B:
= 2 × 8
= 16
Total:
= 20 + 16

Answer:
[tex]5/4\ or\ 1 \frac{1}{4}[/tex]
Step-by-step explanation:
Step 1: Determine a common denominator
Looking at the bottom of the fractions, also known as the denominator, we see that we are given 6, 3, and 12 which all can be multiplied to have the denominator as 12.
Step 2: Convert the fractions to have a common denominator
[tex]5/6 * (2/2) = 10/12[/tex]
[tex]1/3 * (4/4) = 4/12[/tex]
[tex]1/12 * (1/1) = 1/12[/tex]

During the first year of opening his law firm, a lawyer served 46 clients. In the second year, his number of clients grew to 62. If a linear trend continues, write an equation that gives the number of clients c the lawyer will have t years after beginning his firm.
Answer:
There were 3 associates and 5 partners in the case.
Since a law firm is going to designate associates and partners to a big new case, and the daily rate charged to the client for each associate (A) is $ 500 and the daily rate for each partner (P) is $ 1000, and the law firm assigned a total of 8 lawyers to the case and was able to charge the client $ 6500 per day for these lawyers' services, to determine the equation that represents the total number of lawyers on the case, and to effectively determine these numbers, the following calculations must be made:
A + P = 8
500A + 1000P = 6500
1000 x 8 = 8000
8000 - 6500 = 1500
1500/500 = 3
3 x 500 + 5 x 1000 = 6500
Therefore, there were 3 associates and 5 partners in the case.
Can someone please find C. Ive been at it for a long time and its bothering me
Answer:
C(8, -16)
Step-by-step explanation:
Line L has equation x + 2y = 16.
Solve for y.
2y = -x + 16
y = -(1/2)x - 8
Point B is on the x-axis, so its y-coordinate is 0.
x + 2y = 16
x + 0 = 16
x = 16
The coordinate of point B are (16, 0).
y = (-1/2)x + 8
The y-intercept of line AB is (0, 8).
E(0, 8)
AE = EB
From point B to point E, go 16 units left and 8 units up.
E(0, 8)
From point E to point A, also go 16 units left and 8 units up.
A(-16, 16)
Line M is perpendicular to line L, so the slope of line M is 2.
The equation of line M is
y = mx + b
m = 2
y = 2x + b
Line M includes point A(-16, 16)
16 = 2(-16) + b
b = 48
y = 2x + 48 (Equation of line M)
The x-intercept of line M is where y = 0.
0 = 2x + 48
2x = -48
x = -24
Point D has coordinates (-24, 0).
Since line DC is parallel to line L, to go from point D to point C is the same as going from point A to point B.
Go right 32 and down 16.
(-24, 0) becomes (8, -16)
C(8, -16)
If x = 2 and y = 0, what is the value of xy.

Find the positive constant c that makes the quadratic the square of a binomial.
x^2+cx+25
Help would really be appreciated. put it up for 50 points
Answer:
I think its 6
Step-by-step explanation:
Answer:
Step-by-step explanation:
Outline
You could have 2 values. The way to get them is to take the square root of 25, c is double the value you get for the first step. Why 25? Well you only have 1 other choice and that is the 1 that is in front of the x^2. That's not very helpful.
Formula
c = ± 2*sqrt(25)
Solution
c = ± 2 * sqrt(25)
c = ± 2 * 5
c = ± 10
Comment
Where does the ± come from?
You need to get + 25
If you have (x - 5)(x - 5) the last term will be -5 * - 5 = 25
Similarly you get the same result with (x + 5)(x + 5)
