To solve you multiply 4x5=20 and 3x7=21. The numbers are not equal, so they are not proportional. (Hope this helps!)

Answer:

No they are not proportional.

Step-by-step explanation:

If you make the ratio into a fraction it looks like this

4/7 and 3/5

Now you cross multiply

4*5 and 3*7

Now you have 20 and 21

Those numbers are unequivelent

So they are not proportional

Why is it possible to have two different rational functions with the same asymptotes?
jolli1 [7]

Answer: Down below.

Step-by-step explanation:

A horizontal asymptote for a function is a horizontal line that the graph of the function approaches as x approaches ∞ (infinity) or -∞ (minus infinity). ... There are literally only two limits to look at, so that means there can only be at most two horizontal asymptotes for a given function

nikklg [1K]

Answer:

Part A: yes

Part B: 50%

Step-by-step explanation:

There are two ways we can use a normal approximation for a sample: if the population it is from is normally distributed, or if the sample is sufficiently large (n > 30).  In this case, we don't know if the population is normally distributed, but we do know the sample size is larger than 30, so we can use normal approximation.

The sample proportion is normally distributed, with a mean equal to the mean of the population.  So there is a 50% chance that sample proportion is less than the population proportion.

Find the area of the figure. Use 3.14 for it.
Tcecarenko [31]

Answer:

<u>963.73 m²</u>

Step-by-step explanation:

<u>To Find :-</u>

Area of the figure

<u>Solving :-</u>

Area (figure) =  Area (triangle) + Area (semicircle)

= 1/2bh + 1/2πr²

= 1/2 (30 x 34 + 3.14 x 17 x 17)

= 1/2 (1020 + 289 x 3.14)

= 1/2 (1020 + 907.46)

= 1/2 (1927.46)

= <u>963.73 m²</u>
