Seven different names were put into a hat. A name chosen 100 times. And the name Michael is chosen 9 times. What is experimental

iris [78.8K]

Answer:

Experimental probability = 9 / 100

Theoretical probability = 1/7

Step-by-step explanation:

The experimental probability of an event is written as :

P = number of times event occur / total number of trials

Experimental probability is based on the outcome of an experiment that has taken place.

Theoretical probability is based on expected outcome of an event.

P = number of expected or required outcomes / total possible outcomes

Experimental probability of choosing the name Michael is :

Number of times Michael is chosen / number of trials

Experimental probability = 9 / 100 = 0.09

Theoretical probability of choosing michael:

Number of names in hat = 7

Number of names called Michael in hat = required outcome = 1

P = 1 / 7

If the number of names in hat was different from 7, then the theoretical probability will change.

Also, if the number of times a name was chosen was different from 100, then number of trials will also change and hence, the experimental probability.

Factor the expression. 24x+3

Olin [163]

Answer:

Step-by-step explanation:

24x = 3 * 8 * x

3 = 3 * 1

Greatest common factor = 3

24x +3 = 3*8x + 3*1

=3(8x + 1)

1) WET SURPRISE A water balloon is launched off of a patio. The path of the water

mart [117]

The function of the water balloon is an illustration of a quadratic function.

The balloon will splat on the ground after 2.5 seconds

The function is given as:

$h(t) = -6t^2 + 13t + 5$

When the balloon splats on the ground, the value of h(t) is 0.

So, we have:

$-6t^2 + 13t + 5 = 0$

Expand the expression

$-6t^2 + 15t- 2t + 5 = 0$

Factorize the above expression

$-3t(2t - 5)- 1(2t - 5 )= 0$

Factor out 2t - 5 in the 2t - 5

$(-3t - 1)(2t - 5 )= 0$

Split the equation into 2

$-3t - 1 = 0\ or\ 2t - 5= 0$

Rewrite as:

$-3t = 1\ or\ 2t = 5$

Solve for t

$t = -\frac 13\ or\ t = \frac 52$

The value of t cannot be less than 0 i.e. negative.

So, we have

$t = \frac 52$

Divide 5 by 2

$t = 2.5$

Hence, the balloon will splat on the ground after 2.5 seconds

Charles will babysit for up to 4 hours and charges $7 per hour. Write a function in function notation for this situation.

Sloan [31]

X hour and 7 dollars per hour

x = hour

7(x) is your function

thank you for Anlian for pointing it out.. there is 4 hours

so x = 4

plug in 4 in x. 7(4)

7 x 4 = 28

28 is your answer

hope this helps
