The odds against a spinner showing an even number are 3:8. What is the probability of the spinner showing an even number?

1 answer:

6 0

Odds: yes/no
Probability: yes/total

3:8 represents odds of 'not even' which is the same as odds of an odd number being spun.
There are 3 odd numbers and 8 even numbers.
P(even) = 8/11

Amir stands on a balcony and throws a ball to his dog, who is at ground level.

Bumek [7]

Answer:

16 meters

Step-by-step explanation:

The height function is given by:

$h(x)=-(x+1)(x-7)\\h(x)=-(x^2+x-7x-7)\\h(x)=-x^2+6x+7$

The value of x, in seconds, for which the derivate of the height function is zero, is the time at which the maximum height occurs:

$\frac{dh(x)}{dx}= h'(x)=-2x+6=0\\x=3$

For x = 3 seconds, the height is:

$h(3)=-(3^2)+6*3+7\\h(3)=16\ m$

The maximum height that the ball will reach is 16 meters.

Rus_ich [418]

Answer:

-19/36

Step-by-step explanation:

We can find the slope using

m = ( y2-y1)/(x2-x1)

m = ( 94-56)/( 28 -100)

= 38 / -72

= -19/36
