Answer:

Step-by-step explanation:

First, figure out the circumference:

c= $\pi$ d

c= $\pi$ 180=565.48

Then divide by the space needed:

565.48÷70=8.07

With 18 tables and 8 people per table:

18x8=144

So they only have seating for 144 guests.

Solve the quadratic equation y^2-2y-35=0

soldier1979 [14.2K]

Hello,

To solve we need to factor y^2-2y-35:

(y-7)(y+5)=0

Now solve for :

(When will (y-7)(y+5)equal zero?)

When y-7=0 or y+5=0

Solve for the 2 equations above and;

y= 7,-5

Hope this helps, have a great day!

garri49 [273]

Answer:

$\frac{3}{5}$

Step-by-step explanation:

Given parameters:

Number of white balls = 24

Number of black balls = 16

Unknown:

The probability that white ball is drawn at random = ?

Solution:

The probability of an event is the likelihood of such an event to occur. That an event will occur has a probability of 1, it will not occur have a probability of zero.

In this problem, the total number of outcomes of drawing any ball has sample space of (24 + 16)outcomes = 40outcomes.

Probability of an event = $\frac{number of successful outcome}{sample space}$

Pr(white balls) = $\frac{24}{40}$ = $\frac{3}{5}$
