A committee of 5 people is to be chosen from a group of 6 men and 4 women. How many committees are possible if: only men(3 Points)
Answer:
There are six possible committees if only men are chosen
Step-by-step explanation:
Here, we want to find the number of possible committees if only men are chosen
In this case, what will happen is that we shall be selecting the 5 people from the available 6 men
Mathematically, we can have this in 6C5 ways
which is read as 6 combination 5 ways
And that will be 6 ways
So there are six possible committees if only men are selected
Can somebody please help me with this math problem
Answer:
According to the question 25% of the students wore jackets.
Thus 25% of 12 wore jackets
The number of students can be found easily by multipling 12 with 25//100
12*25/100
12*1/4
12/4
thus, 3 students
Therefore, option 3 is correct
A book shop offers a 24% discount on books.
Sam has to pay $______????
if he purchases books with an original price of $84.
Answer:
$63.84
Step-by-step explanation:
If Sam purchases an $84 book with 24% off, he pays $63.84. This is because first you want to find what percent of the book Sam has to pay for. Because it is 24% off, Sam has to pay for 76% of the book (100-24). Then, convert 76% to a decimal (.76) by moving the decimal to the left two digits. Lastly, multiply 84 by .76.

70 + x + 55 + 30 = 180
Answer:
x=25
Step-by-step explanation:
First, we add all like terms. Then, we solve for x.
[tex]70+x + 55 + 30 = 180\\x+70 + 55 + 30 = 180\\x+155=180\\x=25[/tex]
We can rearrange some things because order does not matter with addition. Next, we just use basic equation solving techniques.
Answer:
25. Hope this helps :)
Step-by-step explanation:
180-70=110
110-55=55
55-30=25
Your missing answer would be 25

1÷2 7/9 =x+4 2/5 x
Brainlest I promise!!!!!!!!
Answer:
x=1/15
Step-by-step explanation:
SOLVE:
1 (divide) 2 7/9 = x+ 4 2/5x
1 (divide) 25/9 = x + 4 2/5x
1 * 9/25 + 5 2/5x
9/25 = 5 2/5x
divide both sides by 5 2/5 or you can multiply by the reciprocal
5 2/5x = 27/5x
then once you do that you get x= 1/15
CHECK ANSWER:
Insert 1/15 instead of x
1 (divide) 2 7/9 = (1/15) + 4 2/5 (1/15)
9/25 = 9/25 Yes it is a true statement.
ANSWER:
x= 1/15

a positive real number is 2 more than another. if the sum of the squares of the two numbers is 14, find the numbers
9514 1404 393
Answer:
√6 -1 ≈ 1.44949√6 +1 ≈ 3.44949Step-by-step explanation:
Let x represent the smaller number. Then the sum of squares is ...
x² +(x+2)² = 14
2x² +4x +4 = 14 . . . eliminate parentheses
2x² +4x -10 = 0 . . . put in standard form
x² +2x -5 = 0 . . . . . divide by 2 (because we can)
(x +1)² -6 = 0 . . . . . complete the square
x +1 = √6 . . . we want the positive root
x = -1 +√6
x+2 = 1 +√6
The numbers are √6±1.

Jasmine drives every morning to her office that is 12 miles from her home.
c
Suppose Jasmine drives from home to the office in 20 minutes. Use this information and part (b) to write an equation. QUICK RSM HELL EMERGENCY DUE TOMARO
Answer:
d = 36tStep-by-step explanation:
We need to calculate the speed of Jasmine first as shown:
Speed = Distance/Time
Given:
Distance = 12miles
Time = 20mins
Time = 20/60 hr
Time = 1/3 hr
Speed = 12/(1/3)
Speed = 12 * 3/1
Speed = 38mi/hr
From the formula:
S = d/t
To get the equation needed, substitute s = 36 into the formula:
36 = d/t
d = 36t
Hence the required equation is d = 36t where d is the distance in miles and time in hour
Answer:
36

The sum of three different numbers is 223. The largest number is 13 more than the smallest number. The sum of the largest number and the smallest
number is 7 more than twice the middle number. What is the largest of these numbers?
Answer:
82.
Step-by-step explanation:
Let the largest number of be 'a'.
Let the middle number be 'b'.
Let the smallest number be 'c'.
From the question given above,
The sum of the three numbers is 223. This can be written as:
a + b + c = 223 .... (1)
The largest number is 13 more than the smallest number. This can be written as:
a = c + 13 ..... (2)
The sum of the largest number and the smallest number is 7 more than twice the middle number. This can be written as:
a + c = 2b + 7..... (3)
Summary:
a + b + c = 223 .... (1)
a = c + 13 ..... (2)
a + c = 2b + 7..... (3)
Substitute the value of a in equation 2 into equation 3. This is illustrated below:
a + c = 2b + 7
a = c + 13
c + 13 + c = 2b + 7
2c + 13 = 2b + 7
Make b the subject
2c + 13 – 7 = 2b
2c + 6 = 2b
2(c + 3) = 2b
Divide both side by 2
b = 2(c + 3) / 2
b = c + 3 ..... (4)
Substitute the value of a in equation 2 and the value of b in equation 4 into equation 1. This is illustrated below:
a + b + c = 223
a = c + 13
b = c + 3
(c + 13) + (c + 3) + c = 223
c + 13 + c + 3 + c = 223
3c + 16 = 223
Collect like terms
3c = 223 – 16
3c = 207
Divide both side by 3
c = 207/3
c = 69
The smallest number (c) is 69
Substitute the value of c into equation 2 to obtain the largest number (a). This is illustrated below:
a = c + 13
c = 69
a = 69 + 13
a = 82
Therefore, the largest number (a) is 82
An urn contains nine blue balls and seven yellow balls. If three balls are selected randomly without being replaced, what is the probability that of the balls selected, one of them will be blue and two of them will be yellow?
Answer:
[tex]Probability = \frac{27}{80}[/tex]
Step-by-step explanation:
Given
[tex]Blue =9[/tex]
[tex]Yellow = 7[/tex]
Required
Determine the probability that one of the balls is blue while others is yellow
The order of selection may be any of these three:
Yellow, Yellow, Blue or Yellow, Blue, Yellow or Blue, Yellow, Yellow
Solving Yellow, Yellow, Blue
[tex]Probability = P(Y_1) * P(Y_2) * P(B)[/tex]
[tex]Probability = \frac{7}{16} * \frac{6}{15} * \frac{9}{14}[/tex]
[tex]Probability = \frac{1}{8} * \frac{1}{5} * \frac{9}{2}[/tex]
[tex]Probability = \frac{9}{80}[/tex]
Solving Yellow, Blue, Yellow
[tex]Probability = P(Y_1) * P(B) * P(Y_2)[/tex]
[tex]Probability = \frac{7}{16} * \frac{9}{15} * \frac{6}{14}[/tex]
[tex]Probability = \frac{9}{80}[/tex]
Solving Blue, Yellow, Yellow
[tex]Probability = P(B) *P(Y_1) * P(Y_2)[/tex]
[tex]Probability = \frac{9}{16} * \frac{7}{15} * \frac{6}{14}[/tex]
[tex]Probability = \frac{9}{80}[/tex]
Hence:
The required probability is:
[tex]Probability = \frac{9}{80} + \frac{9}{80} + \frac{9}{80}[/tex]
[tex]Probability = \frac{27}{80}[/tex]

Web crawlers need to estimate the frequency of changes to Web sites to maintain a current index for Web searches. Assume that the changes to a Web site follow a Poisson process with a mean of 6 days. Let a random variable X denote the time (in days) until the next change. What is the probability that the time until the next change is greater than 9.5 days
Answer:
The probability will be "0.205".
Step-by-step explanation:
The probability that perhaps the time remains greater than 9.5 days before the next shift will indeed be:
⇒ [tex]P(X>9.5)[/tex]
⇒ [tex]1-P(X<9.5)[/tex]
⇒ [tex]1-(1-exp(\frac{-9.5}{6} ))[/tex]
⇒ [tex]0.205[/tex]

The sum of the angles of a triangle is 180 degrees. If one of the acute angles of a right triangle is 52 degrees, what is the measure of the other acute angle? A: Let x be the measure of the unknown acute angle. Write an equation relating this measure to the known quantities. Do not include units in your equation.
Answer:
An equation is [tex]x+52\°+90\°=180\°[/tex]
Step-by-step explanation:
Let [tex]x[/tex] be the measure of the unknown acute angle.
According to angle sum property of a triangle, sum of all the angles of a triangle is equal to 180°.
One of the acute angles of a right triangle is equal to 52°.
Also, the triangle is a right angled triangle, one of the angle must be equal to 90°.
[tex]x+52\°+90\°=180\°\\x+142\°=180\°\\x=38\°[/tex]
So, an equation is [tex]x+52\°+90\°=180\°[/tex]
