Answer:

The balance in the bank after 5 years of 6.5% interest is $5,300.

Step-by-step explanation:

*Presuming that this is not a compounding interest the interest would just multiply by the even balance.*

So every 5 years the balance earns 0.065 of 4,000 dollars.

This would make our equation:

4000 + (4000  x .065 x 5 )

= 4000 + (1300)

= 5300

The balance in the bank after 5 years of 6.5% interest is $5,300.

The range for the given scenario is y≥0.

Given that, Tina graphed the function on the coordinate grid to show f(x), the height of the dropped ball, in feet, after its xth bounce.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Part A:

From the graph we can see that, for f(3) that is for 3 bounces the height is 4 feet.

Part B: Tina said that a possible range for the given function is y > 0.

From the graph we can see that for f(7) and f(8), the ball is almost at rest position. So the range can be y≥0.

Therefore, the range for the given scenario is y≥0.

Answer: the third option

Step-by-step explanation:

The third option means less than or equal to, so if 1/4 of a number is no more than 2/3, it is less than or equal to 2/3

The correct symbol for the inequality is ≤

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Given that, Michaela needs to represent this statement as an inequality.

One-fourth of a number is no more than two-thirds.

So, in the given options, the third option means less than or equal to,

so if 1/4 of a number is no more than 2/3, it is less than or equal to 2/3

Hence, the inequality will be =

x/4 ≤ 2/3

Hence, the correct symbol for the inequality is ≤

The frequency for 2 to 7 is 3

The frequency for 8 to 13 is 4

The frequency for 14 to 19 is 2

The grouped frequency distribution for the data with the given intervals is 3, 4 and 2 respectively.

Given that, nine cyclists were each asked the distance in miles they biked last week. The distance travelled by 9 cyclists is 16, 8, 2, 6, 8, 11, 9, 15 and 7.

We need to complete the grouped frequency distribution for the data.

In this type, the data is arranged and separated into groups called class intervals. The frequency of data belonging to each class interval is noted in a frequency distribution table. The grouped frequency table shows the distribution of frequencies in class intervals.

Now, the frequency distribution for the given intervals is as follows:

That is, for intervals 2 to 7 the frequency is 3.

For intervals 8 to 13 the frequency is 4.

For intervals 14 to 19 the frequency is 2.

Therefore, the grouped frequency distribution for the data with the given intervals is 3, 4 and 2 respectively.
