Answer:

First blank(reading from top to bottom left to right) : 21 second blank: 21 third blank: 5 fourth blank: 4 fifth blank: 5.25 or 5 and 1/4 or 21/4

Step-by-step explanation:

To solve this you will first need to make 4 and 1/5 into a improper fraction. To do that you multiply 4 and 5 and get 20. Then you add the 1, and get 21. That will go in your first blank. Next you will remember your KCF (Keep Change Flip) rule. Keep the 20/5, change the division sign to a multiplication sign, and flip 4/5 to 5/4. Next you will just multiply across. 21*5=105 5*4=20 The Directions say to have your answer in simplest form. 105/20 is not in it's simplest form. To make 105/20 in simplest form you would just divide. Your answer on a calculator makes out to be: 5.25. That is just 5 and 1/4 in fraction form, or 21/4 in improper fraction form.

Answer:

answer below

Step-by-step explanation:

They want you to put the first fraction in mixed numbers.

21/5 divided by 4/5

When dividing fractions flip the second fraction

21/5 times 5/4

Then multiply across

105/20 = 21/4 or 5.25

Answer: The pack of 20.

Step-by-step explanation:

It is because a pack of 20 sells for 2.50 for each pencil, and the pack of 12 sells for 2.51 per pencil, so that means the pack of 20 is cheaper.

Jack plotted the graph below to show the relationship between the temperature of his city and the number of ice cream cones he s

timurjin [86]

Answer:

(a) The amount of ice cream increase as temperature increases

(b)

$y = 2x + 5$ --- equation

$y = 5$ --- y intercept

$m = 2$ --- slope

Step-by-step explanation:

Given

See attachment for graph

Solving (a): The relationship between the variables

From the attached graph, the dots on the graph increases towards up-right direction. This implies that there is a positive correlation between the variables.

In other words;

The amount of ice cream increase as temperature increases

Solving (b): The line of best fit

First, we draw a line through the points (the line should have almost equal points on both sides; see attachment 2).

From (2), we select any 2 points on the line:

$(x_1,y_1) = (15,35)$

$(x_2,y_2) = (0,5)$

The slope (m) is:

$m = \frac{y_2 -y_1}{x_2 - x_1}$

$m = \frac{5-35}{0-15}$

$m = \frac{-30}{-15}$

$m = 2$

So, the line of best fit is:

$y = m(x - x_1) + y_1$

Substitute known values:

$y = 2(x - 0) + 5$

$y = 2(x) + 5$

$y = 2x + 5$

The y-intercept is when $x=0$

So, we have:

$y = 2*0 + 5$

$y = 0 + 5$

$y = 5$

You are challenged to a lucky draw game. If you draw a face card (K, Q, J) from a standard deck of cards, you earn 10 points. If

sveticcg [70]

There are 3 face cards for each of the 4 suits, leading to a total possible gain of 120, there are 40 other cards leading to a total possible loss of 80.
120 - 80 = 40.
40 / 52 (total number of cards) = about .77

Final Answer:
The expected value of a draw is positive 0.77 points.
Hope I helped :)
