Hi how are you doing today Jasmine

Step-by-step explanation:

Oliver deposits P= $1,000

Then total amount A after n months given that the balance increases by %15 each month can be calculated as

[tex]A= 1000(1+15/100)^n[/tex]

Assuming the increase in amount is compounded monthly.

Answer:

4 dollars, $4

Step-by-step explanation:

As for the cost being on the side and the amount of bag tags being on the bottom, thats the first step, to study the cost to tag ratio.

1st dot: 8:2

2nd dot: 4:16

3rd dot: 24:8

Now, simply divide 8 from 2, you get 4.

Divide 4 from 16, you get 4

Lastly, divide 24 from 8 and you get 4.

That all rounds up to a integer 4 :}

Hope it helps!!

Answer:

4

Step-by-step explanation:

Answer:

1) x = 14

2) x = 25

Step-by-step explanation:

1)

3x - 2 + 50 = 90

3x + 48 = 90

3x = 42

x = 14

2)

4x + 2 + 78 = 180

4x + 80 = 180

4x = 100

x = 25

Answer:

10% of people don't like either. Your answer is 120 people.

Step-by-step explanation:

Step-by-step explanation:

Let the required integers be x,x+1,x+2.

Therefore,

x+x+1+x+2=45

3x+3=45

3x=42

x=14

Hence, the required integers are 14,15,16.

Answer:

10.4 miles

Step-by-step explanation:

c(m) = trip cost

c(m) = 6.75 + 3.2m

40.03 = 6.75 = 3.2m

33.28 = 3.2m

m = 10.4

Answer:

Cream = 3 cups

Chocolate = 6 cups

Step-by-step explanation:

Cream = 1 cup

Chocolate = 2 cups

Total = 3 cups

Cream : chocolate = 1 : 2

He uses 9 cups of these two ingredients. How many cups of chocolate does he use in this candy recipe?

Cream = ratio of cream/total ratio of total cups

= 1/3 of 9

= 1/3 × 9

= 3 cups

Cream = 3 cups

Chocolate = ratio of chocolate/total ratio of total cups

= 2/3 of 9

= 2/3 × 9

= 6 cups

Chocolate = 6 cups

Given:

The sequence is 8, 10, 12.5, 15.625,...

To find:

The explicit formula for the given sequence.

Solution:

We have,

8, 10, 12.5, 15.625,...

Here, the first terms is 8.

[tex]\dfrac{10}{8}=1.25[/tex]

[tex]\dfrac{12.5}{10}=1.25[/tex]

[tex]\dfrac{15.625}{12.5}=1.25[/tex]

The common ratio is 1.25. So, the given sequence is a geometric sequence.

The explicit formula for a geometric sequence is:

[tex]a_n=ar^{n-1}[/tex]

Where, a is the first term and r is the common ratio.

The explicit formula for the given geometric sequence is:

[tex]a_n=8(1.25)^{n-1}[/tex]

Therefore, the correct option is A.

Answer:

The y-intercept of the line is 9.

Step-by-step explanation:

y-y1=m(x-x1)

y-1=-2(x-4)

y-1=-2x+8

y=-2x+8+1

y=-2x+9

y=mx+b where m=slope and b=y-intercept

Answer:

See attachment for histogram

Step-by-step explanation:

Given

[tex]Data: 21,22.4,23,24.8,25.3,27,27.6,28.8,29.4,29.9,30.1,30.1,30.4,31.2,32,32.9[/tex]

Required

Represent on histogram

Calculate the range of the data

[tex]Range = 32.9 - 21[/tex]

[tex]Range = 11.9[/tex]

Using a width of 5, we have:

[tex]Class = \frac{Range}{5}[/tex]

[tex]Class = \frac{11.9}{5}[/tex]

[tex]Class =2.38[/tex]

Round up

[tex]Class = 3[/tex]

This means that the class will have 3 classes which are:

21.0 - 24.9, 25.0 - 29.9  and 30.0 - 34.9

The frequency table is as follows:

[tex]\begin{array}{cc}{Interval} & {Frequency}&{21.0 - 24.9} & {4} & {25.0 - 29.9} & {6} & {30.0 - 34.9} & {6} \ \end{array}[/tex]
