There are 264 male students in the high school containing 600 students.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
There are 600 students altogether, hence:
Number of freshmen = (1/5) * 600 = 120
Number of other graders = 600 - 120 = 480
Number of male freshmen = 120 - (0.4 * 120) = 72
Number of male other graders = (1 - 3/5) * 480 = 192
Total number of male = 72 + 192 = 264

There are 420 fans at a high school basketball game. The ratio of students to parents is 5 to 2. Exactly how many more students are there than
parents at the game?
Answers
Answer:
180 more students than parents at the game
Step-by-step explanation:
There are 5 students for every 2 parents equalling 7 people in one set of students to parents ratio.
There are 420 fans at the game. Divide the 420 by the 7 people per set.
420 / 7 = 60 (There are 60 sets of 5 students to 2 parents ratio)
Multiply the 60 sets by 5 students and 2 parents, respectively:
60 x 5 = 300 students
60 x 2 = 120 parents
Subtract the number of parents from number of students:
300 students - 120 parents = 180 more students

What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100.
At a local high school, enrollment in the drama club increases by 5%.
Let an initial number of students in high school be 'a'.
so next year increase in students will be = 5% of a
= 5/100 × a
= 0.05a
and total number of the students will be = ( a + 0.05a )

if I made 136$ and gave 35% to my brother how much would he get
Answers
Answer:
47.6
Step-by-step explanation:
35% x 136
= (35/100)*136
_________________
Step 1: In the given case Output Value is 136
Step 2: Let us consider the unknown value as x
Step 3: Consider the output value of 136 = 100%
Step 4: In the same way, x = 35%
Step 5: On diving the pair of simple equations we got the equation as under
136 = 100% (1).
x = 35% (2).
(136%)/(x%) = 100/35
Step 6: Reciprocal of both the sides results in the following equation
x%/136 = 35/100
Step 7: Simplifying the above obtained equation further will tell what is 35% of 136
x = 47.6%
Therefore, 35% of 136 is 47.6

Answer:
5^15
Step-by-step explanation:
Using the laws of powers, you can multiply 5^3 out of its bracket and get 5^27. Then, once again, using the laws of powers, you can get 5^15 by subtracting the powers.
Answer:
(5^3)^9/5^12 is equivalent to 5^15
Step-by-step explanation:
Begin by simplifying (5^3)^9
To make it much easier, apply the power rule. (a^x)^y = a^xy)
Multiply 3 x 9 = 27... so we get 5^27
Next, instead of dividing 27/12, which will result in a decimal..you must do 27-12, which is applying the quotient rule. (a^x / a^y = a^x-y)
5^27/5^12 = 5^27-12 = 5^15
( When I use /, it signifies to divide.)
So, (5^3)^9/5^12 is equivalent to 5^15! Hope this helps! :D

Answers
Heating and Cooling Degree Days
Degree days are based on the assumption that when the outside temperature is 65°F, we don't need heating or cooling to be comfortable. Degree days are the difference between the daily temperature mean, (high temperature plus low temperature divided by two) and 65°F. If the temperature mean is above 65°F, we subtract 65 from the mean and the result is Cooling Degree Days. If the temperature mean is below 65°F, we subtract the mean from 65 and the result is Heating Degree Days.
Step-by-step explanation: Example 1: The high temperature for a particular day was 90°F and the low temperature was 66°F. The temperature mean for that day was:
( 90°F + 66°F ) / 2 = 78°F
Because the result is above 65°F:
78°F - 65°F = 13 Cooling Degree Days
Example 2: The high temperature for a particular day was 33°F and the low temperature was 25°F. The temperature mean for that day was:
( 33°F + 25°F ) / 2 = 29°F
Because the result is below 65°F:
65°F - 29°F = 36 Heating Degree Days.
The calculations shown in the two examples above are performed for each day of the year and the daily degree days are accumulated so that we can compare months and seasons.
The table below represents the data collected at a sandwich shop for the last six months with respect to the type of bread people ordered (sourdough or wheat) and whether or not they got cheese on their sandwich.
Are the events “sourdough” and “with cheese” independent events? Explain why or why not using probabilities. Show all work to receive full credit.
Answers
Answer:
First, add totals to the table (see attachment)
Let S = Sourdough
Let C = With cheese
[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]
[tex]\implies \sf P(S)=\dfrac{1225}{3125}=\dfrac{49}{125}[/tex]
[tex]\implies \sf P(C)=\dfrac{2000}{3125}=\dfrac{16}{25}[/tex]
[tex]\implies \sf P(S \cap C)=\dfrac{800}{3125}=\dfrac{32}{125}[/tex]
For independent events S and C,
[tex]\sf P(S \cap C)=P(S)P(C)[/tex]
[tex]\sf\:As\quad P(S) \cdot P(C)=\dfrac{49}{125} \cdot \dfrac{16}{25}=\dfrac{784}{3125}[/tex]
[tex]\sf And\quad \dfrac{32}{125} \neq \dfrac{784}{3125}[/tex]
[tex]\sf Then \quad P(S \cap C)\neq P(S)P(C)[/tex]
So the events are NOT independent

Answers
The length of line segment l n on which point m lines in between is 64 units. Option 4 is the correct option.
What is the length of line segment?Length of a line segment is the distance of both the ends of it.
Point m lies between points l and n on line segment l n .
The space between l and m is 10x 8. The space between m and n is 5x -4.The value of line segment LN is,
[tex]LN = 12x +16[/tex]
The sum of LM and LN is equal to the line segment LN. Thus,
[tex]LM+MN=LN\\10x +8+(5x-4)=12x+ 16\\10x +8+5x-4=12x+ 16\\10x+5x-12x=16 -8+4\\3x=12\\x=\dfrac{12}{3}\\x=4[/tex]
Put this value of x in the equation of line segment LN,
[tex]LN = 12(4) +16\\LN=48+16\\LN=64\rm\; units[/tex]

What is the circumference of a circle with a diameter of 8 inches?
a 12.56
b 25.12
c 50.24
d 200.96
Answers
A Circle is a closed plane geometric shape figure. The diameter of a circle is the longest chord of a circle. The radius drawn perpendicular to the chord bisects the chord. A Circle is always lie at an equal distance from a center point. Circles having different radius are similar.
Circumference of Circle:The circumference of a circle is the product of pi and length of the diameter of a circle. Mathematically;
[tex]\longrightarrow \tt{Circumference_{(circle)} = \pi{D}}[/tex]
Here, D is the diameter of the circle or distance between the circle.
Elucidation:We are asked to find the circumference of the circle if the diameter is 8 inches.
We know that, The circumference of a circle is the product of pi and length of the diameter of a circle. Therefore;
[tex]\implies \tt{Circumference_{(circle)} = \pi{D}}[/tex]
[tex]\implies \tt{Circumference_{(circle)} = 3.14 \times 8}[/tex]
[tex]\implies \boxed{\pmb{\tt{Circumference_{(circle)} = 25.12}}}[/tex]
Hence, the circumference of the circle is 25.12 inches. So option (B) is correct.
Answer:
Circumference of circle = 25.12 inchesThus Option B is correct .Step-by-step explanation:
In the question we are given that diameter of circle is of 8 inches . And we have asked to find the circumference of the circle .
For finding circumference of circle we must have to know that what is the formula for finding circumference of circle. So :
[tex] \quad \quad \: \red{\underline{\pink{ \boxed{ \frak{Circumference \: of \: Circle =2 \pi r }}}}}[/tex]
Where ,
π refers to 3.14 r refers to radius of circleSolution : -
As in the question we are given length of diameter . So for finding circumference we need to find the radius of circle .
We know that diameter of circle is two times its radius ,
[tex] \qquad \: \rm {Diameter = 2 × Radius }[/tex]
So for radius we are dividing both side with 2 :
[tex]\qquad \: \rm { \dfrac{Diameter}{2} = \dfrac{ \cancel{2} × Radius}{ \cancel{2}} }[/tex]
We get that ,
[tex] \qquad \: \rm {Radius = \dfrac{Diameter}{2} }[/tex]
Therefore , we can say that radius of circle is half of its diameter .
Now using this , firstly we are finding radius of circle . So :
[tex] \longmapsto \quad \: \boxed{\rm{ Radius = \frac{8}{2} \: \: inches}}[/tex]
Therefore , radius of circle is 4 inches .Now , we are moving towards our final solution .
So ,
[tex] \longmapsto \quad Circumference_ { (Circle)} =2 \times 3.14 \times 4 [/tex]
Multiplying 2 with 3.14 :
[tex]\longrightarrow \quad Circumference_ { (Circle)} = 6.28 \times 4 [/tex]
Multiplying 4 and 6.28 :
[tex]\longrightarrow \quad \purple{{\boxed{\frak{Circumference_ { (Circle)} = 25.12\: inches }}}}[/tex]
Therefore , circumference of circle having diameter 8 inches is 25.12 inches and hence option b is correct .#Keep Learning19. True or false: If the n columns of S (eigenvectors of A) are independent, then (a) A is invertible. (b) A is diagonalizable. (c) S is invertible. (d) S is diagonalizable

(c) S is invertible true statement.

Note that if n columns of S (eigen vectors of A) are said to be independent.
One can deduce or see that the eigen vector that is similar to the eigen value is said to be = 0 and one can say it is linearly independent when viewed with the other eigen vectors of A.
But because to the zero eigen value of A, we see that the determinant of A is the output of eigen values of A which is = 0 and as such, A is not invertible.
So, the linear independence of eigen vectors will not be able to find the invertibility of A and as such A is diagonalizable.
