again taking 4 as x and 5 as y.

since,

y = f(x)

5 = f(4)

that is option 3.

x = -3

y = -5

y = f(x) = -5

f(-3) = -5

1st option

V(r) = 4/3 pi r³

here the ou.tput is V(r) when the input is r.

and since V(r) denotes volume of air inside the basketball

V(r) is the volume of basketball when the radius is r.

that is option 2.

given that:-

x = 9, f(x) = 5

•°• f(9) = 5

that is the 1st option

1.f(0) = 6

2.f(4)=5

3.f(-3)=-5

4. V(r) represent volume of basketball when radius is r

5.f(9) =5

In a chess club the probability that Shaun will beat Mike is 3/8 .

romanna [79]

Answer:

$\frac{10}{56} = 0.1786$ probability that Shaun loses both games

Step-by-step explanation:

Games are independent, so we find each separate probability, and multiply them.

In a chess club the probability that Shaun will beat Mike is 3/8.

So $1 - \frac{3}{8} = \frac{8}{8} - \frac{3}{8} = \frac{5}{8}$ probability that Shaun loses.

The probability that Shaun will beat Tim is 5/7 .

So $1 - \frac{5}{7} = \frac{2}{7}$ probability that Shaun loses.

What is the probability that Shaun loses both games?

This is:

$p = \frac{5}{8} \times \frac{2}{7} = \frac{5*2}{8*7} = \frac{10}{56} = 0.1786$

$\frac{10}{56} = 0.1786$ probability that Shaun loses both games

There are 6 times as many males as females on the maths course at university. What fraction of the course are male? Give your an

Mumz [18]

Assign x as the number of females.

Since makes are six times more: 6x is the male variable.

In total there are 7x students.

So the fraction for males is : 6/7

There's no way to simplify further because there's no term common to both the denominator/numerator.

Answer: 6/7
