Evaluate C(7, 4) 35 210 5,040

sashaice [31]

Answer:

$\boxed{\boxed{C(7,4)=35}}$

Step-by-step explanation:

Here, we have to calculate

$C(7,4)=\dbinom{7}{4}$

From combination we know that,

$\dbinom{n}{r}=\dfrac{n!}{r!(n-r)!}$

Here,

n = 7 and r = 4, so putting these,

$\dbinom{7}{4}=\dfrac{7!}{4!(7-4)!}$

$=\dfrac{7!}{4!\ 3!}$

$=\dfrac{5040}{24\times 6}$

$=\dfrac{5040}{144}$

$=35$

A soccer stadium had a capacity of 25000 seats, but with the new area built this increased by 20%.

sergij07 [2.7K]

Answer:

19,500 people

Step-by-step explanation:

20% of 25,000 is 5,000.

Add 5,000 to 25,000 - this will give you 30,000. That is a 20% increase.

65% of 30,000 is 19,500, thus there are 19,500 people in the stadium.

What is the area of the composite figure?

Sunny_sXe [5.5K]

You would have to split up the shape.

The top square: A= 100

Trapezoid: A= 44

Rectangle: A= 120

100 + 44 + 120 = 264

A= 264

I roughly estimated on what the bottom measurement it, so if its wrong; oops
