In a certain Algebra 2 class of 29 students, 5 of them play basketball and 16 of them play baseball. There are 10 students who p

kkurt [141]

ANSWER
$P(both\:sports)= \frac{2}{29}$

EXPLANATION
Let the number who plays both games be
$x$
Then those who play only basketball
$= 5 - x$

and those who play only baseball
$= 16 - x$

We were given that 10 students play neither sports.

We can then write the following equation,

$(5 - x) + x + (16 - x) + 10 = 29$

This implies that,

$- x + x - x = 29 - 5 - 16 - 10$

This simplifies to,

$- x = - 2$

This gives us,

$x = 2$

Therefore the number of students play both basketball and baseball is 2.

The probability that a student chosen from the class plays both basketball and baseball ball

$= \frac{2}{29}$

sukhopar [10]

Answer:

A) The population of this survey is the registered voters in the city of Raleigh.

B) 9500

C) 200

D) 0.325

E) 3088

Step-by-step explanation:

A) The population of this survey is the registered voters in the city of Raleigh.

B) Population size can be defined as the total number of individuals in a population. Here the total number of individuals are the registered voters in the city. Therefore the size of the population is 9500.

c) Sample size is defined as the number of individual samples in a statistical test. Here the sample size is the 200 randomly selected registered voters. It is denoted as "n".

d) The sample statistic for the proportion of voters surveyed who said they'd vote for Brown would be:

p' = voters for brown / sample size

$p' = \frac{65}{200} = 0.325$

The sample statistic for the proportion of voters surveyed who said they'd vote for Brown is 0.325

E) The expected number of voters for Brown based on the sample:

0.325 * 9500 = 3087.5

Approximately 3088

The expected number of voters for Brown based on the sample might be 3088 voters.
