frank liked to buy packs of baseball cards. on 3 different days, he bought 3 packs. on 3 other days, he bought 4 packs each day. After that he splits his packs with his 2 brothers. How many packs will they each have. Choose the expression that best matches this situation.

Answers

Answer 1

Answer:

First, frank buys 3 packs on 3 different days, so in those first 3 days he buys:

3*3 = 9 packs.

Then on other 3 days he buys 4 packs each day, so he has:

3*4 = 12 packs.

In total he haves:

9 + 12 = 21 packs.

Now he divides the packs with his 2 brothers (So we divide 21 packs between 3 people)

Then each brother gets:

N = 21/3 = 7 packs each.

Write a difference quotient that best approximates the instantaneous rate of change of g at x=0

Please show how you got your answer

Answers

We can define the average rate of change of a function f(x) in an interval [a, b] as:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

Particularly, if we want to find an approximation of the rate of change for a particular value x', we can choose:

a < x' < b

Such that a and b are really close to x'.

Then if we want to find the instantaneous rate of change of g at x = 0, we need to find values of a and b really close to zero.

Looking at the table, we can choose:

a = -0.001

b = 0.001

(are the two closer ones to zero)

Then the rate of change can be written as:

[tex]f(x) = \frac{g(0.001) - g(-0.001)}{0.001 - (-0.001)} = \frac{2.001 - 1.999}{0.002} = 1[/tex]

From that, we can conclude that a good approximation of the instantaneous rate of change is 1.

5) A data set with whole numbers has a low value 20 and high value of 82. Find the class width and class limits for a frequency table with 7 classes.

Answers

Answer:

Class width = 9

Class limits = 20 - 28; 20 - 28; 29 - 37; 38 - 46; 47 - 55; 56 - 64; 65 - 73; 74 - 82.

Step-by-step explanation:

We are given;

Highest value = 82

Lowest value = 20

Frequency = 7

Formula for class width is;

Class width = (Highest Value - Lowest Value)/number of classes

Class width = (82 - 20)/7

Class width = 8.8 ≈ 9

Now,since class width is 9, limits between 20 and 82 would be done at intervals of 9.

Thus;

Class limits = 20 - 28; 20 - 28; 29 - 37; 38 - 46; 47 - 55; 56 - 64; 65 - 73; 74 - 82.

On a trip to the grocery store, Zach purchased 7 pounds of fruits and vegetables. How many
kilograms is 7 pounds? Round your answer to the nearest hundredth of a kilogram.

Answers

Answer:

3.18 kg

Step-by-step explanation:

It is given that, Zach purchased 7 pounds of fruits and vegetables.

We know that,

1 kg = 2.20462 pounds

It means that, 1 pound = 0.453592 kg

We need to find how kilograms is 7 pounds. So multiply 7 by 0.453592 to convert into kg.

So,

7 pound = 3.17515 kg

or

7 pounds = 3.18 kg

So, the weight of fruits and vegetables is 3.18 kg.

there are twelve bottles in each box of bottled water. Write an equation representing the total number of bottles you get if you buy x boexes. use y to represent the total number of of bottles

Answers

Answer:

what does y and x represent no one can answer unless they have x and y

Step-by-step explanation:

Answer:

y=12x

Step-by-step explanation:

Since there are 12 bottles in each box, the total number is the number of boxes multiplied by 12.

For example, buying 1 box will give you 12 bottles (1x12) and buying 2 boxes would give you 24 (2x24).

Therefore the equation of the total number of bottles if you buy x boxes is:

y=12x
