Answer:

D) 36 bottles for $4 by 1.4¢ per bottle

Step-by-step explanation:

We calculate bottle per dollar for each option.

#A

Bottles/Dollar=\frac{24\ bottles}{\$3}=8 bottles/dollar

#Both B and C charges the same as A and will have bottle/dollar ration of 8:1

#D

=\frac{36}{4}\\\\=9

Hence, D is the better buy  as it gives you 9bottles per $1 spent as compared to the 8 bottles per $1 spent as in the other 3 options.

If the mean I.Q. is 100 and the standard deviation of I.Q. scores is 15, then an I.Q. of 130 will have a z score (or standard sc
skad [1K]

Answer: I.Q. of 130 will have a z score (or standard score) of 2.

Step-by-step explanation:

Let X be a random variable that represents the  I.Q. score.

Formula for Z-score : Z=\dfrac{X-mean}{standard \ deviation}

As per given, mean I.Q. = 100 and the standard deviation =15

For X = 130,

Z=\dfrac{130-100}{15}=\dfrac{30}{15}=2

So, I.Q. of 130 will have a z score (or standard score) of 2.

Use the conditional statement to answer the question.
yarga [219]

the correct option is the first one:

"Yes, both the statement and the converse are true."

<h3>How to use the conditional statement?</h3>

Here we have the conditional statement:

"If a number is odd, then it is not divisible by 2"

Now we have the question:

"Can the statement be written as a biconditional and why?"

A biconditional statement is of the form:

"P if and only if Q"

And this means that if any of the two propositions is true, then the other is also true.

In this case:

P = a number is odd.

Q = it is not divisible by 2.

Now, by definition, even numbers are these that are divisible by 2 and odd are these that are not.

Then the statements:

"If a number is odd, then it is not divisible by 2"

"If a number is not divisible by 2, then it is odd"

are true.

So the conditional and the converse are true, this implies that the biconditional statement is also true.

Then the correct option is the first one:

"Yes, both the statement and the converse are true."
