Answer:

Step-by-step explanation:

Stem and Leaf Plots

It is a special table where each data value is split into a stem (the first digit or digits) and a leaf (usually the last digit).

So, in the given plot

the first stem 2 has leafs = 6,7,7

So, the numbers will be 26,27,27

So, in this way we can write the stem leaf plot data in normal data form

Now to calculate range

Range = Highest number - lowest number

The first stem 2 and its first leaf 6 . So,number = 26 is the lowest number

The third stem 4 and its last leaf 5 . So, number = 45 is the highest number

Thus Range = 45-26=19

Hence the range of data is 19

The range is the difference between the lowest and the highest number.

the answer is 30.5

Answer: $55.35

Step-by-step explanation:

if the bill is $46.15, round it up to $46. Twenty percent of that is $9.20, found by moving the decimal point one place left. Add $9.20 to $46.15, and you get $55.35

i hope this is correct and it helps :)

Classify the function as linear or quadratic and identify the quadratic, linear, and constant terms. y=(3x+4)(-2x-3)

MissTica

Y=(3x+4)(-2x-3)=-6x^2-4x-9x-12=-6x^2-13x-12.
It is a quadratic function because it has x in power 2 (x^2)

Nolan has some nickels and some dimes. He has no more than 19 coins worth no less than $1.30 combined. If Nolan has 5 nickels, d

Allushta [10]

Answer:

number of dimes 11 to 14

Step-by-step explanation:

given data

coin = 19

worth no less = $1.30

Nolan nickles = 5

solution

we convert 5 cent to dollars, it will be

5÷100 = $0.05

and

dime is worth 10 cents

so it will be 10 ÷ 100 = $0.1

so we consider here x as the number when nickels.

and we consider y as the number of dimes.

so here we can say

x + y ≤ 19 ..........................1

as here no less than $1.30 combined.

0.05 x + 0.1 y ≥ 1.3 ......................2

and

when Nolan has 5 nickels

put x = 5 in eq 1

5 + y ≤ 19

y ≤ 19 - 5

y ≤ 14

and

now we put x = 5 in eq 2

0.05 × 5 + 0.1y ≥ 1.3

0.25 + 0.1y ≥ 1.3

0.1y ≥ 1.3 - 0.25

0.1y ≥ 1.05

y ≥ 10.5

so all possible values for the number of dimes 11 to 14
