John went to the store to buy trail mix for a hike. He could buy 3 pounds of packages for $2.49 or 8 pounds of packages for $6.4

Lelechka [254]

First what I did was find how much each pound would cost per different package.

So starting off with the 3 pound package. I did 2.49 divided by 3 to find out how much each pound would weigh.

2.49 / 3 = 0 . 83

So each pound in the 3 pounded package would cost $0.83.

Now to see how much the 8 pound package would cost. Just like the 3 pound package I had to find how much each pound would weigh. So I divided 6.49 by 8.

6.49 / 8 = 0.81125

So looking at the results the 3 pound package would be the best option. You are getting more for less.

You are dealt a card from a standard 52 card deck , what is the probability of getting an ace

Tema [17]

Answer:

0.1538

Step-by-step explanation:

Probability of being dealt with an ace of a 8 =

= Number of ace + number of an 8 in the deck / Total number of cards in the deck

= (4+4) / 52 = 8/52 = 0.1538

Therefore 0.1538 is the required probability here.

NOOOOOOO LIIIIIINNNNKKKKKKSSSSSSSS Kalvin sells bottlea of water at baseball games. He pays $0.75 per bottle and $3.78 for the i

Andrei [34K]

Answer:

C. C = 0.75b + 3.78

Step-by-step explanation:

We know that Kalvin sells bottles of water, in which he charges 75 cents for each one, with an additional 3.78 for ice.

Easily enough, we know that 0.75 has to be with a variable, because there is 75 cents being charged "per bottle." Therefore look for an answers that has the expression "0.75b".

This would leave us with "C."

Explain how the graph of y = 2csc(x - pi/4) - 5 is related to the graph of the basic trigonometric function y = cscx.

Ymorist [56]

Answer: The distance between the min and max increased by a factor of 2, horizontally shifted to the right by $\bold{\dfrac{\pi}{4}}$ , shifted down 5 units, and has a phase shift of $\bold{\dfrac{\pi}{4}}$

Step-by-step explanation:

The general form of a csc function is: y = A csc (Bx - C) + D where

|A| is the amplitude (vertical stretch)
-A is a reflection over the x-axis
|B| is the horizontal stretch
-B is a reflection over the y-axis
C is a horizontal shift (left or right)
D is a vertical shift (up or down)

Period is $\dfrac{2\pi}{B}$
Phase Shift is $\dfrac{C}{B}$

In the given transformed graph y = 2 csc (x - $\dfrac{\pi}{4}$ ) - 5

A = 2 --> distance between the Min and max is 2(2) = 4
C = $\dfrac{\pi}{4}$ --> horizontally shifted to the right $\dfrac{\pi}{4}$ units
D = -5 --> shifted DOWN 5 units
Phase shift is $\dfrac{\pi}{4}$
