Given data
number of employee= 25
number of team=3
The expression for combination is given as
C(n,r)=(nr)=n!/(r!(n−r)!)
C(25,3)=25!/(3!(25−3)!)
C(25,3)=25!/(3!(22!)
C(25,3)=25*24*23*22!/3!(22!)
C(25,3)=25*24*23*/3!
C(25,3)=25*24*23*/3*2*1
C(25,3)=25*24*23*/6
C(25,3)=13800/6
C(25,3)=2300 ways
The number of ways where a store manager arranges a group is 50,600.
Given that,
There is a group of 1 team leader and 3 team workers from his 25 employees.Based on the above information, the calculation is as follows:
[tex]= ^25C_4 \times 4C_1\\\\= \frac{25!}{4!(25-4)!} \times \frac{4!}{1!(4-1)!} \\\\= \frac{25!}{4! \times 21!} \times \frac{4!}{1! \times 3!} \\\\= 12,650 \times 4[/tex]
= 50,600
Therefore we can conclude that the number of ways where a store manager arranges a group is 50,600.

Suppose there are 15 freshman, 16 sophomores, 10 juniors, and 12 seniors running for the offices of president, vice president, and secretary. If no person can hold more than one office, in how many different ways could these people be elected to these positions
Answer:
Number of ways = 140,556
Step-by-step explanation:
Total person = 15 + 16 + 10 + 12
Total person = 53
Number of not included bperson = 3
Computation:
Number of ways = !53 / !(53-3)
Number of ways = 53 x 52 x 51
Number of ways = 140,556
In City A, the temperature rises F from 8 A.M. to 9 A.M. Then the temperature drops F from 9 A.M. to 10 A.M. In City B, the temperature drops F from 8 A.M. to 9 A.M. Then the temperature drops F from 9 A.M. to 10 A.M. Write an expression that represents the change in temperature from 8 A.M. to 10 A.M. for each city. Simplify and interpret each sum. Use pencil and paper. Which city has the greater change in temperature? Which expression represents the change in temperature for City A?
Here is the full question.
In city A, the temperature rises 9° F from A.M to 9 A.M. Then the temperature drops 8°F from 9 A.M. to 10 A.M. in city B, the temperature drops 1°F from 8 A.M. to 9 A.M. Then the temperature drops 3°F from 9 A.M. to 10 A.M.
Write an expression that represents the change In temperature from 8 A.M. to 10 A.M for each city. Simplify and interpret each sum. Use a pencil and paper. Which expression represents the change in temperature for city A?
Answer:
In City A, the expression for the change in temperature is = 9 + (-8)
The amount the temperature changes for City A = 1°F
In City B, the expression for the change in temperature is -1 + (-3)
The amount the temperature changes for City B = -4°F
Thus, City A has a greater change in temperature.
Step-by-step explanation:
From the information above; Given that:
In City A, the rise in temperature from 8 A.M to 9 A.M is = 9°F
In City A, the drop in temperature from 9 A.M to 10 A.M = 8°F
Similarly;
In City B, the drop in temperature from 8 A.M to 9 A.M = 1°F
In City B, the drop in temperature from 9 A.M to 10 A.M = 3°F
∴
For City A
The temperature change from 8 A.M to 10 A.M are :
8 A.M to 9 A.M = +9°F
9 A.M to 10 A.M = -8°F
In conclusion, The sum for the change from 8 A.M to 10 A.M = 9 + (-8) = 1°F
For City B
The temperature change from 8 A.M to 10 A.M are:
8 A.M to 9 A.M = -1°F
9 A.M to 10 A.M = -3°F
In conclusion, The sum for the change from 8 A.M to 10 A.M = -1 + (-3) = -4°F

40% of 750 is 300 you can confirm this because 75 is 10% of 750 and 75 * 4 = 300.
A certain brand of TV has a 50% chance of being defective. Which model could be used to determine the probability that when two TVs are chosen, they will both be defective? Roll a die four times Flip a coin twice Flip a coin four times None of the above
Answer:
The answer is "Flip a coin twice".
Step-by-step explanation:
The probability, that its damage would be (HH, TT, HT, TH) if two of the TVs were selected, that's why the answer is "Flip a coin twice" is the correct.

Explanation:
If y is the short leg of the 30-60-90 triangle, then y*sqrt(3) is the length of the longer leg. The short leg is always opposite the shortest angle.
We're given that 5*sqrt(3) is the longer leg, so
y*sqrt(3) = 5*sqrt(3)
y = 5
After we divide both sides by sqrt(3)
Side note: x = 2y = 2*5 = 10.

Heya mate!
If you observe the figure, the longest side always resides the opposite place of the right angle. Accordingly the perpendicular is 5√3 units in measure.
With this, the hypotenuse is x and the base is y. We need to find y. By doing some smart work! Let's guess the trigonometric ratio that we give us the relation between y and 5√3 because one of the angle given is 60°
⇛ tan a = Perpendicular / Base
Plugging the values of a, and Perpendicular to find the base of the triangle i.e. y.
⇛ tan 60° = 5√3 / y
⇛ √3 = 5√3 / y
⇛ y = 5√3 / √3
⇛ y = 5 units
Hence, the Correct Option is Option A.
Find the value of x in the triangle shown below.

If you do not see a number next to a variable, what is it understood to be?
what is the Y intercept
y= 4x - 9
Answer:
b = –9
Step-by-step explanation:
First, refer to the slope-intercept formula:
y = mx + b
In this formula, m is the slope and b is the y-intercept.
That means in y = 4x – 9, the b variable is –9, which is the y-intercept.
Answer: the answer is A. because the y intercept is -9.

Answer:
Jules would need 30 yards of fencing.
The yards of fencing that would be needed is 30√2 yards.
What is the length of the square?
In order to determine the length of the fence, the Pythagoras theorem would be used.
The Pythagoras theorem: a² + b² = c²
where:
a = length
b = base
c = hypotenuse
30² + 30²
= 900 + 900
= √1800
= 30√2 yards

The answer is choice C it's the only one that actually touches point (0, -7) and increases after that point.
Graph 1:
If we take a look at graph 1 we see that it does cross the y-axis at (0,-7), but sadly it doesn't increase.
Graph 2:
If we take a look at graph 2 we see that it does cross over y-axis but not at (0,-7). It also doesn't increase but that doesn't matter anymore.
Graph 3:
If we take a look at graph 3 we see that it crosses the y-axis at (0,-7) and it also increases. Although it decreases before it doesn't matter, it only has to increases after it hits (0,-7).

Step-by-step explanation:
[tex] \tt{5 \frac{4}{5} - 3 \frac{1}{3} }[/tex]
Convert the mixed number into improper fraction
[tex] \tt{↦ \: \frac{5 \times 5 + 4}{5} - \frac{3 \times 3 + 1}{3} }[/tex]
[tex] \tt{↦ \: \frac{25 + 4}{5} - \frac{9 + 1}{3}} [/tex]
[tex] \tt{ ↦ \: \frac{29}{5} - \frac{10}{3} }[/tex]
While performing the addition or subtraction of unlike fractions , you have to express the given fractions into equivalent fractions of common denominator and add or subtract as we do with like fractions. Thus, obtained fractions should be reduced into lowest terms if there are any common on numerator and denominator. But in case of improper fraction, it needs to be deduced on mixed fraction. Now,
Take the L.C.M of 5 and 3
prime factors of 5 = 1 × 5
prime factors of 3 = 1 × 3
L.C.M = Common factors × Remaining factors
= 1 × 5 × 3
= 15
[tex] \tt{↦ \frac{29 \times (15 \div 5)}{15} - \frac{10 \times (15 \div 3)}{15} }[/tex]
[tex] \tt{↦ \: \frac{29 \times 3}{15} - \frac{10 \times \: 3 }{15} }[/tex]
[tex] \tt{↦ \: \frac{87}{15} - \frac{30}{15}} [/tex]
While performing the addition or subtraction of like fractions , you just have to add or subtract the numerator respectively in which the denominator is retained same.
[tex] \tt{ ↦ \: \frac{87 - 30}{15} }[/tex]
[tex] \tt{↦ \: \frac{37}{15} }[/tex]
Convert the improper fraction into mixed fraction.
[tex] \tt{↦ \boxed{ \tt{ 2 \frac{7}{15} }}}[/tex]
And we're done!

The Probability distribution table shows the proportion of people living in five different regions of a city. What is the probability that a person chosen at random, who lives in the city, lives in the central or north region.
The probability that a person chosen at random, who lives in the city, lives in the central or north region is 0.56
What is the probability?A probability is a number that reflects the chance or likelihood that a particular event will occur.
Given that, the Probability distribution table shows the proportion of people living in five different regions of a city
Probability = Favourable Outcomes/Total Outcomes
Probability(of selecting a person from central or north region) = 0.44 + 0.12 = 0.56
Hence, probability that a person chosen at random, who lives in the city, lives in the central or north region is 0.56
