1. Use the expression 10 x ? where? represents a factor between 1 and 9. What is true about the digit in the ones place of each

marishachu [46]

We want to study a general product, and find information about the ones place.

We will see that the ones place is always zero.

We have the expression:

10×?

Where ? can be any number between 1 and 9 (only whole ones)

What is true about the digit of the ones place (the first digit at the left of the decimal point) in each product?

Let's give ? some different values and see what happens:

10×1 = 10

10×2 = 20

10×3 = 30

etc...

We can see that the ones place will always be equal to zero.

If Karri takes a 7 question true false test and guess on every question, what is the

dusya [7]

Answer:

The probability that she gets all 7 questions correct is 0.0078.

Step-by-step explanation:

We are given that Karri takes a 7 question true-false test and guess on every question.

The above situation can be represented through binomial distribution;

$P(X = r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r} ; x = 0,1,2,3,........$

where, n = number of samples (trials) taken = 7 question

r = number of success = all 7 questions correct

p = probability of success which in our question is probability that

question is correct, i.e. p = 50%

Let X = Number of question that are correct

So, X ~ Binom(n = 7, p = 0.50)

Now, the probability that she gets all 7 questions correct is given by = P(X = 7)

P(X = 7) = $\binom{7}{7} \times 0.50^{7} \times (1-0.50)^{7-7}$

= $1 \times 0.50^{7} \times 0.50^{0}$

= 0.0078
