densk [106]

Given that Frank's electric bill has a cycle day of the 3rd and due date is 8 days later, so that would have a due date of 11th of the month. Since it has a one day grace period which is 12th of the month, this means that if Frank pays his electric bill on the 12th of the month, he won't be paying any late or penalty fee. Hope this helps.

On a multiple choice test with 17 questions, each question has four possible answers, one of which is correct. For students who

Ira Lisetskai [31]

<h2>The required "option c) 4.3" is correct.</h2>

Step-by-step explanation:

Given,

Total number of multiple choice questions = 17

To find, the mean for the number of correct answers = ?

Each question has four possible answers.

If guessing at random:

There is only one in four chances.

$\dfrac{1}{4}\times 100$ = 25 % chance of getting a particular question right.

This is the same probability for each of the 17 questions.

If there is a 25 % chance of getting any given question right.

There are 17 questions.

∴ The total number of questions you will expect to get right =

25 % × 17

= $\dfrac{25}{100} \times 17$

= $\dfrac{17}{4}$

= 4.25

≈ 4.3

∴ The mean for the number of correct answers = 4.3

Thus, the required "option c) 4.3" is correct.

Pls I need help with this

LiRa [457]

Answer:

third side = 4

Step-by-step explanation:

third side is hypoenuse as it is opposite to 90 degree.

using pythagoras theorem

(perpendicular)^2 + (base)^2 = (hypotenuse)^2

2^2 + (2 $\sqrt{3$ )^2 = hypotenuse^2

4 + 4*3 = hypotenuse^2

16 = hypotenuse^2

$\sqrt{16}$ = hypotenuse

4 = hypotensue

Wanda and Kyle want to compare the worth of their baseball cards. Wanda has 80 baseball cards and Kyle has 110 baseball cards. S

chubhunter [2.5K]

Answer:

Mean

Step-by-step explanation:

If Wanda has 80 baseball cards and Kyle has 110 baseball cards. Given that they know the total value of all their individual base ball cards, the worth of each baseball card will be derived by dividing the Total Worth of the cards by the number of cards. This is an example of Mean. Therefore they should use Mean to compare the worth of the cards.

Illustrative Example

If the Total Value of their cards are $500,

For Wanda, Value Per Card= $500/80 Cards =$6.25 per card

Similarly,

For Kyle, Value Per Card= $500/110 Cards =$4.55 per card

So we can see from this illustration whose card is with an higher price using the mean.
