The following table gives the scores of 30 students in a mathematics examination. Scores 90–99 80–89 70–79 60–69 50–59 Students

Pavel [41]

The given data is
Scores: 90-99 80-89 70-79 60-69 50-59
Students: 3 7 12 4 4
Because we are to take the middle value for each group.
Therefore the total score is
Sx = 3*94.5 + 7*84.5 + 12*74.5 + 4*64.5 + 4*54.5 = 2245
The number of students is 3+7+12+4+4 = 30

The mean is
m =2245/30 = 74.833

Calculate (Sx - m)²
(Sx - m)² = 3*(94.5-74.833)² + 7*(84.5-74.833)² + 12*(64.5-74.833)²
+ 4*(64.5-74.833)² + 4*(54.5-74.833)² = 3896.7

Calculate the standard deviation
s = √(3896.7/29) = 11.592

Answer:
mean = 74.83
std. deviation = 11.59

Rocko paid $12.50 for 25 game tickets.

soldi70 [24.7K]

Answer:

The constant of proportionality is 0.5

Step-by-step explanation:

We are given the following in the question:

Cost of 25 game tickets = $12.50

Cost of 35 game tickets = $17.50

The cost of ticket C(n) is directly proportion to the number of tickets n.

Thus, we can write:

$C(n) \propto n\\C(n) = an$

where a is the constant of proportionality.

Putting values, we get,

$12.50 = 25a\\\\\Rightarrow a = \dfrac{12.50}{25}\\\\\Rightarrow a = 0.5$

Thus, the constant of proportionality is 0.5
