The second graph  is the correct one

Answer:

The second table.

Step-by-step explanation:

In the first table, the speed goes from 45 down to 43; then down to 41; then up to 42; then up to 43.  It decreases and then increases.  This is not the correct table.

In the second table, the speed goes from 45 up to 47; then up to 49; then down to 48; then down to 47.  It increases and then decreases; this is the correct table.

To verify, we check the last two tables.  The third table stays at 45, then decreases to 43 and 41.  This is not correct.

The last table decreases from 45 to 43, then decreases to 41, then stays constant.  This is not correct.

The second table is the only correct one.

Mice21 [21]

Answer:

43,758 different swimmer squad

Step-by-step explanation:

Given;

Total Number of athletes n = 18

Number of athletes needed to be selected r = 8

For this case, the coach need to select 8 players from a total of 18 athletes with no particular order. So, this is a combination case since the order of selection is not relevant.

The number of different swimmer squads the coach could select is;

S = nCr

nCr = n!/(r!×(n-r)!)

Substituting the values of n and r;

S = 18C8

S = 18!÷(8! × (18-8)!)

S = 18! ÷ (8!×10!)

S = 43,758

Therefore, he can select 43,758 possible different squads

X+x-z; use x=3 & z=4​
nadezda [96]

Answer:

2

Step-by-step explanation:

Order of operations is not as applicable in this situation because we're just dealing with addition and subtraction.  This is a simple case of plugging in values for the given expression.

x = 3

z = 4

So it becomes...

3 + 3 - 4

6 - 4

2

So with the given expression of x + x - z and the given values of x = 3 and z = 4, the expression should sum to: 2
