The theoretical probability of at least one 4 on the spinners is 0.4375

<h3>(a) The number of different outcomes</h3>

The sections on the spinners are:

Spinner 1 = 4

Spinner 2 = 4

So, the number of different outcomes is:

Outcomes = 4 * 4

Outcomes = 16

Hence, the number of different outcomes is 16

<h3>(b) The theoretical probability of at least one 4 on the spinners</h3>

The spin results that have at least one 4 are:

Results = {(4,1), (4,2), (4,3), (4,4), (1,4), (2,4), (3,4)}

The count of these results is 7.

So, the theoretical probability of at least one 4 on the spinners is:

P = 7/16

P = 0.4375

Hence, the theoretical probability of at least one 4 on the spinners is 0.4375

<h3>(c) Why the theoretical probability and the experimental probability are different?</h3>

The theoretical probability and the experimental probability are different because:

Experimental probabilities are based on the actual experiment
Theoretical probabilities are based on the logic

What is 33.61111111 in fraction form

madreJ [45]

The correct answer is: " $\frac{33,611}{1,000}$ " .

____________________

<u>Step-by-step explanation</u>:

Based on the assumption that the "1" repeats infinitely; in the given value:

" 33.61111111 ...." ;

_______

Note that the "611" ; after the decimal point; this goes to the "thousandths";

place (is "3 (three) digits long.").

_______

As such; we rewrite the number as:

_______

" $\frac{33.611}{1}$ " ;

and we multiply BOTH the "numerator" And the "denominator" by: "1000" :

_______

→ " $\frac{(33.611)*(1000)}{(1)*(1000)}$ " ;

to get:

→ " $\frac{33611}{1000}$ " ; → which cannot be reduced any further.

_______

The correct answer is: " $\frac{33,611}{1,000}$ " .

_______

Hope this is helpful to you!

Wishing you the best!

Laura answered 27 questions correct on a test on her test and scored 90%. How many questions where on the test?

Nadya [2.5K]

The number of questions in the test is 30

Step-by-step explanation:

Let's call the total number of questions in the test N.

We know that Laura answered 27 questions, and these 27 questions represent the 90% of the test.

Therefore, we can say that 27 is the 90% of N.

Re-writing the percentage as a fraction,

$90\% = 0.90$

This means that:

$0.90 N = 27$

And now we can solve for N to find the number of questions in the test:

$N=\frac{27}{0.90}=30$
