There are 150 people ina golf club.a) there are 50%more men than women in the golf club. How many mena nd how many women are ther in the golf club.

Answers

The percentage computed shows that the number of women is 60 while men are 90.

How to calculate percentage?

Let the number of women be represented by x.

Since there are are 50% more men than women in the golf club, the number of men will be:

= x + (50% × c)

= x + 0.5x

= 1.5x

Therefore, 1.5x + x = 150

2.5x = 150

x = 150/2.5

x = 60

Number of women = 60

Number of men = 1.5x = 1.5 × 60 = 90

How much greater is the average rate of change over the interval [6,8] than the interval [5,7]?

Answers

Answer:    536

============================================================

Explanation:

The average rate of change is the same as the slope of the line through the endpoints mentioned.

The interval [6, 8] means that we're talking about [tex]6 \le x \le 8[/tex]

When x = 6, we have y = f(x) = 1178When x = 8, we have y = f(x) = 2742

So we're tasked to find the slope of the line through (6,1178) and (8,2742)

We'll use the aptly named slope formula.

[tex](x_1,y_1) = (6,1178) \text{ and } (x_2,y_2) = (8,2742)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{2742 - 1178}{8 - 6}\\\\m = \frac{1564}{2}\\\\m = 782\\\\[/tex]

The slope through those two endpoints is 782, which is the average rate of change on the interval [6, 8].

------------------

For the interval [5,7] we have [tex]5 \le x \le 7[/tex]

According to the function table,

When x = 5, y = 690When x = 7, y = 1852

Like before, use the slope formula to find the slope through (5,690) and (7,1182)

[tex](x_1,y_1) = (5,690) \text{ and } (x_2,y_2) = (7,1182)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{1182 - 690}{7 - 5}\\\\m = \frac{492}{2}\\\\m = 246\\\\[/tex]

This is the average rate of change on the interval [5,7].

------------------

The last step is to subtract the slopes:

782 - 246 = 536 which is the final answer

let n (AUB)=32n(B)=16and n(ANB)9 find n (A)​

Answers

Answer:

32

Step-by-step explanation:

n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)

Given n(A)= ? we represent with x

n(B)= 16

n(A∪B) = 32

Substituting in equation 1 to get n(A)

32  = n(A) + 9 − 9

⇒n(A) = 32 − 0

n(A)  = 32

to confirm this we put the values into the formula below

n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)

32 =  32 + 9 - 9

Answer:

  n(A) = 25

Step-by-step explanation:

The relation between cardinality of two sets and that of their union and intersection is ...

  n(A∪B) = n(A) +n(B) -n(A∩B)

  32 = n(A) +16 -9 . . . . . use the given information

  application of L'Hopital's rule to the presumed indeterminate form yields this conclusion

Step-by-step explanation:

This is a reverse application of L'Hopital's rule for determining the limits involving indeterminate forms.

When the expression evaluated at the limit is 0/0, then L'Hopital's rule tells you the limit can be found from n'/d', where n and d are the numerator and denominator of the original expression, respectively.

We can see that x-π = 0 at x=π, so we assume that f(π) = 0 as well, and the expression n/d = f(x)/(x-π) evaluates to the indeterminate form 0/0.

The derivatives are ...

  n' = f'(x)

  d' = 1

Then we have the limit as ...

  lim{x→π) = n'/d' = f'(π)/1 = 3   ⇒   f'(π) = 3

The conclusion f(π)=0 and f'(π)=3 follows from L'Hopital's Rule.

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 70 The truck is transporting 60 large boxes and 55 small boxes. If the truck is carrying a total of 4050 pounds in boxes, how much does each type of box weigh?

Answers

Step-by-step explanation:

x = weight of a small box

y = weight of a large box

x + y = 70 pounds

55x + 60y = 4050 pounds

from the first equation we get

x = 70 - y

and we can use that identity in the second equation :

55(70 - y) + 60y = 4050

3,850 - 55y + 60y = 4050

5y = 200

y = 40 pounds

x = 70 - y = 70 - 40 = 30 pounds

so, a small box weighs 30 pounds, and a large box weighs 40 pounds.

So- first, arrange the terms in ascending order.

[22, 22, 23, 23, 29, 29, 29, 31]

There are an even number- eight- terms in total, so we will take the average of the two "middle" terms.

(29+23)/2; 29 and 23 are the "middle" terms, and there are two of them.

(52)/2 = 26

Therefore, the median is 26.
