Answer

C. 49, 17, 4, 18

Step by step explanation

Here mean of all the data set is 88

To find the most spread of data, we need to find the range.

range of set A = The highest value - the lowest value = 36-6 = 30

Range of set B = 30-15 = 15

Range of set C = 49-4 = 45

Range of set D = 30-14= 16

Here the highest range is in Set C.

Therefore, answer is C. 49, 17, 4, 18

Donna's Deli delivers lunches for $7 per person plus a $35 delivery fee. Larry's Lunches delivers lunches for $11 per person.
Katena32 [7]
A.    Cost=7(Number of People)+35          or y=7x+35
b.   11x<7x+35
c.   Subtract 7x from both sides: 4x<35
d. Divide both sides by 4: x< 8.75 people.  This means that if the number of lunches ordered is 8 or less, Larry's Lunches will be cheaper.  However, if the number of lunches ordered is 9 or more, Donna's Deli will be cheaper.  Thus, for an order of 10 lunches, Donna's Deli would charge less.

4x+3y=20<br> 2x+y=7<br> How do I solve this? I forgot how to do it :/ also no answer choice
Crank

So for this, I will be using the substitution method. Firstly, subtract both sides in the second equation by 2x: 4x+3y=20\\ y=7-2x

Next, substitute y in the first equation with 7-2x, then solve for x from there:

4x+3(7-2x)=20\\ 4x+21-6x=20\\ -2x+21=20\\ -2x=-1\\ x=\frac{1}{2}

Now that we got x, substitute it into either equation to solve for y:

4*\frac{1}{2}+3y=20\\ 2+3y=20\\ 3y=18\\ y=6\\ \\ 2*\frac{1}{2}+y=7\\ 1+y=7\\ y=6

In short, x = 1/2 and y = 6.

A magician asks two volunteers to each draw a card from a standard deck of cards. What is the probability that the first card is
mars1129 [50]

Answer:

6.37%

Step-by-step explanation:

A deck of cards have 52 cards.  There are 4 suits of 13 card each, those suits are Hearts, Clubs, Diamond and Spades.

The probability that the first card is a heart is:

P(Hearts) = \frac{13}{52}

Now, the probabily that the second card is a diamond is:

P(Diamond | First card is Heart) = \frac{13}{51}

The Probability that the first card is a heart and the second one a diamond is given by:

P(Hearts)×P(Diamond | First card is Heart)

= \frac{13}{52}\frac{13}{51}

= 6.37%
