At the U.S open tennis championship a statistician keeps track of every serve that a player hits during the tournament. The mean

GarryVolchara [31]

Answer:

Step-by-step explanation:

Both 115 and 145 mph are above the mean. Draw a normal curve and mark these speeds. 115 mph is 1 standard deviation above the mean; 130 would be 2 standard deviations above the mean; and 145 would be 3 s. d. above it.

We need to find the area under the standard normal curve between 115 and 145. This is equivalent to the area under the standard normal curve between z = 1 and z = 3.

I used my TI-83 Plus calculator's DISTR function "normalcdf(" to calculate this area: normalcdf(1, 3) = 0.1573.

The area between z = 1 and z = 3 is 0.1573. In other words, the percentage of serves that were between 115 and 145 mph was 15.73%.

The number of comic books is an illustration of a linear function

The complete equations are: $\mathbf{8b + 17 =65}$ and $\mathbf{b =6}$
The value of b has increased by 4

She had 17 comic books already.

So, we have:

$\mathbf{Base\ Amount = 17}$

Her order of 65 books contains 8 comic books per collection.

So, we have:

$\mathbf{Rate = 8}$

$\mathbf{Total = 65}$

This is represented as:

$\mathbf{Rate \times b + Base\ Amount =Total}$

So, we have:

$\mathbf{8\times b + 17 =65}$

Rewrite as:

$\mathbf{8b + 17 =65}$

Subtract 17 from both sides

$\mathbf{8b =48}$

Divide both sides by 8

$\mathbf{b =6}$

Assume she has 97 books in her collection, then the equation would be represented as:

$\mathbf{8b + 17 = 97}$

Subtract 17 from both sides

$\mathbf{8b = 80}$

Divide both sides by 8

$\mathbf{b = 10}$

The values of b are 6 and 10.

The difference between 6 and 10 is 4

Hence, the value of b has increased by 4
