Ksivusya [100]

The given inequality is 2.5x + 4y ≤ 60. x is the bags of chips and y is the jars of salsa,

Replace x and y in the equation with the possible answers and solve:

A) 10 chips and 2 salsas:

2.5(10) +4(2) = 25 + 8 = 32 This is less than 60 so is a solution.

B) 20 chips, 2 salsas:

2.5(20) + 4(2) = 50 + 8 = 58, this is less than 60 so is a solution.

C) 14 chips, 5 salsas:

2.5(14) + 4(5) = 35 + 20 = 55, this is less than 60 so is a solution.

D) 18 chips , 6 salsas:

2.5(18) + 4(6) = 45 + 24 = 69, this is greater than 60 so is not a solution.

The amount of water that the girls on the basketball and soccer teams drink during one practice session is recorded in the dot p

Radda [10]

Answer:

Step-by-step explanation:

We have two dot plots, one for the Basketball Team and one for the Soccer Team.

Notice that there are 16 girls in the Basketball Team and 16 girls in the Soccer Team.

Basically, the median is between the 8th and 9th term in each data set. Specifically, is the mean between them.

<h3>For Basketball Team</h3>

$m_{basketball} =\frac{32+32}{2}=32$

Because the 8th and 9th term are both equal to 32.

<h3>For Soccer Team</h3>

$m_{soccer}=\frac{64+64}{2}=64$

Because the 8th and 9th term are both equal to 64.

If we subtract them to find the difference, it would be

$\Delta m=64-32=32$

Basically, the Soccer Team drank 32 more ounces of water than the Basketball Team.

Therefore, the right answer is B, that's the closest one.
