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

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!

Hope I helped!

Answer:

The volume of the solid V = 41601.6 π

Step-by-step explanation:

From the given information:

The volume of the shaded region bounded by rotating the shaded region about the y-axis is: dV

[tex]dV = \pi (-1x^2 +3x+18)^2 ((x+dx)^2 -(x)^2)[/tex]

[tex]dV =2 \pi x (-1x^2 +3x+18)^2 \ . dx[/tex]

[tex]dV =2 \pi x (-1x^2 +3x+18) ( -1x^2 +3x + 18). dx[/tex]

[tex]dV =2 \pi x (1x^4 -3x^3 -18x^2 -3x^3 +9x^2 +54x -18x^2 +54x + 324 ) \ .dx[/tex]

[tex]dV =2 \pi x (1x^4 -3x^3-3x^3 -18x^2 +9x^2 -18x^2 +54x +54x +324) \ .dx[/tex]

[tex]dV =2 \pi x (1x^4 -6x^3 -27x^2 +9x^2+ 108x +324) \ .dx[/tex]

[tex]\implies \int ^V_o \ dv = 2 \pi \int ^6_0 (1x^5 -6x^4 -27x^3+108x^2 +324x) \ dx[/tex]

[tex]V = 2 \pi \begin {bmatrix} \dfrac{1x^6}{6} - \dfrac{6x^6}{5} - \dfrac{27x^4}{4}+ \dfrac{108x^3}{3}+ \dfrac{324x^2}{2} \end {bmatrix}^6_0[/tex]

[tex]V = 2 \pi \begin {bmatrix} \dfrac{1(6)^6}{6} - \dfrac{6(6)^6}{5} - \dfrac{27(6)^4}{4}+ \dfrac{108(6)^3}{3}+ \dfrac{324(6)^2}{2} -0\end {bmatrix}[/tex]

V = 2π (20800.8)

V = 41601.6 π

Answer:

Jules would need 30 yards of fencing.

The yards of fencing that would be needed is 30√2 yards.

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

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

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).

Answer:

StartLayout Enlarged Left-Brace 1st Row y = 280 x 2nd Row y = negative 0.052 (x minus 500) squared + 24,000 EndLayout

Step-by-step explanation:

Given that:

Cost per cleaner = $280

The cost of x vacuum cleaners will be :

Cost per cleaner * number of cleaners

$280 * x

= $280x

The general vertex firm equation :

y-k = a(x-h)^2

Vertex = (500, 24000) ; Vertex = (h, k)

h = 500 ; k =24000 y= 11000, x = 0

y intercept = 11000

Plugging the values :

11000 - 24000 = a(0 - 500)^2

- 13000 = a(-500)^2

-13000 = a * 250000

a = - 13000 / 250000

a = - 0.052

Hence,

y - 24000 = a(0 - 500)^2

y = - 0.052(0 - 500)^2 + 24000

Step-by-step explanation:

The greatest common factor is something that can be seen between the two as relation.

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.

The probability that a person chosen at random, who lives in the city, lives in the central or north region is 0.56

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

Answer:

Step-by-step explanation:

You just need to find the number that can divide all the numbers evenly.

I hope this makes sense and I hope this is correct.

Answer:

24?

Step-by-step explanation:

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

Answer:

A, Between 9 and 10 am

Step-by-step explanation:

The math is simple. between 9 and 10 theres 1 hour, and between 28 and 67 there are 39 P(t).

Between 10 and 15 there are 5 hours, and between 67 and 212 there are 145 P(t), which divided by 5 is 29.

You divide by 5 to get the same amount of hours to compare both

9-10 am= 39

10-15am/pm= 29

Therefore, the number of people increased faster between 9 and 10 am.

The rate of increase of population is faster between t = 9 to t = 10.

The ratio of two numbers a and b can be written as a : b = a/b.

The ratio of two quantities is the unit rate of one quantity with respect to the other.

The table for the population and time can be formed as follows,

Population                               Time in hours

28                                                 9

67                                                 10

212                                                15

Now, the increase in population can be obtained by taking the ratios as follows,

Increase in population between t = 9 to t = 10 is given as,

(67 - 28) ÷ (10 - 9)

⇒ 39

And, between t = 10 to t = 15, it is given as,

(212 - 67) ÷ (15 - 10)

⇒ 145 ÷ 5 = 29

Thus, the rate of increase is more from  t = 9 to t = 10.

Hence, the faster increase is given in time interval of  t = 9 to t = 10.
