Answer with explanation:

The Description about the Histogram is

Vertical Axis = 0-14

Horizontal Axis      Bar Height

0-49                            2

50-99                            6

100-149                         12

150-199                            5

200-249                          1

Plotting the Histogram

→Class interval 150-199 has frequency =5, and class interval 50-99, has frequency equal to 6.

→The curve is not uniform on both sides.

→The interval in which mean , median lies has 6+2=8 frequency on the left of that interval , and 5+1=6, values on the right of class interval [100-149].We can conclude that,the histogram is left Skewed.

→But when we join ,mid points of histogram,the curve obtained resembles with a normal distribution curve called bell curve.It is not exactly bell shaped,as not uniform on both sides explained above.

Option C: Approximately bell Shaped

This is an approximately bell-shaped distribution. The highest bar is in the center, with height = 12. Just to its left and right are bars of heights 6 and 5. At the extremes are bars of heights 2 and 1.

If the highest bar was on the left, it would be skewed left (and if it was on the right, skewed right). A uniform distribution would more or less have the same height level over all the bars.

Two tapes, red and green, with lengths of 415 feet and 780 feet respectively are to be cut into pieces of equal length without r
ICE Princess25 [194]

Answer:

The greatest possible length of the pieces is 5 feet

Step-by-step explanation:

Red = 415 feet

Green = 780 feet

Find the greatest possible length of the pieces.

Find the Highest common factor

415 = 1, 5, 83, 415

780 = 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390 and 780

The Highest common factor of 415 and 780 is 5

The greatest possible length of the pieces is 5 feet

Red = 415/5

= 83 pieces

Green = 780/5

= 156 pieces

Population Growth The population of a town of 5000
Nesterboy [21]

Answer:

a) A=5000{(1.03)}^{t}

b) 5464 inhabitants.

Step-by-step explanation:

The formula used for compound interest becomes very helpful in this case.

A=P{(1+r)}^{t}\\\\When:\\A = Final Value\\P = Initial Value\\r = Rate of Change (Decimal)\\t = Time (Years)

Knowing this, we can easily calculate the value for any year, counting from the original 5000.

From this formula, we can derive a specific one that will serve for any value of <em>t</em>.

a)

A=5000{(1+0.03)}^{t}\\A=5000{(1.03)}^{t}

b) Apply the formula:

A=5000{(1.03)}^{3}\\A=5000(1.092727)\\A=5463.635=5464

The town will have 5464 inhabitants.

Whats the answer for 6n+7-2n-14=5n-1​
12345 [234]

Answer:

Simplifying

6n + 7 + -2n + -14 = 5n + 1

Reorder the terms:

7 + -14 + 6n + -2n = 5n + 1

Combine like terms: 7 + -14 = -7

-7 + 6n + -2n = 5n + 1

Combine like terms: 6n + -2n = 4n

-7 + 4n = 5n + 1

Reorder the terms:

-7 + 4n = 1 + 5n

Solving

-7 + 4n = 1 + 5n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-5n' to each side of the equation.

-7 + 4n + -5n = 1 + 5n + -5n

Combine like terms: 4n + -5n = -1n

-7 + -1n = 1 + 5n + -5n

Combine like terms: 5n + -5n = 0

-7 + -1n = 1 + 0

-7 + -1n = 1

Add '7' to each side of the equation.

-7 + 7 + -1n = 1 + 7

Combine like terms: -7 + 7 = 0

0 + -1n = 1 + 7

-1n = 1 + 7

Combine like terms: 1 + 7 = 8

-1n = 8

Divide each side by '-1'.

n = -8

Simplifying

n = -8
