Identify which of the following is most appropriate: discrete random variable, continuous random variable, or not a random varia

liraira [26]

Answer:

A.) Continuous random variable ;Not a random variable ; Discrete random Variable ; Continuous random variable ; discrete random variable

Step-by-step explanation:

Identify which is most appropriate category for the sample data given below :

a. Exact weights of the next 100 babies born in the United States

This is a continuous random varibake as it could take up any value including decimals in other to specify the exact weight of an individual.

b. Responses to the survey question "Which political party do you prefer?"

Not a random variable as the outcome to this question isn't numerical.

c. Numbers of spins of roulette wheels required to get the number 7

This is a discrete random variable as the number of roulette spins would be a whole number within a specified fic range.

d. Exact foot lengths of humans

Continuous random variable

The exact foot length of human would vary greatly and in a bid to give an exact value, foot length will most definitely take up decimal values

e. Shoe sizes (such as 8 or 8½) of humans.

This is also a discrete random variable as shoe sizes are restricted to a specific range. Even with the inclusion of 1/2 in the measurement, there are no values inbetween (8 and 8 1/2) which will be the same for the remaining value range.

A total of 432 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student t

dybincka [34]

Answer:

144 tickets.

Step-by-step explanation:

So first we have to take the total amount of tickets sold and divide that by 3 (because students bought 2/3 of those tickets and adults bought 1/3 of those tickets). So we get the answer of 144. So that means that the adults bought 144 tickets and the students bought 288 tickets.

perfect positive correlation.

As x increases by 1, y increases by 1

y is 1 times x

equation: y = x

(b)

perfect negative correlation.

As x increases by 1, y decreases by -4

y is $-\frac{1}{4}$ times x

equation: y = -4x

The distance between the school and the park is 6 km. There are 1.6 km in 1 mile.How many miles apart are the school and the par

insens350 [35]

As stated 1 mile equals to 1.6 km,
so do calculation to get the 6 km

1 mile = 1.6 km

Then try to divide the 6 km with 1 mile value in km which is 1.6 km so that we know exactly how many miles required to get 6 km

$6 \: \div \: 1.6 \: = \: 3.75$
So the answer is 3.75 miles

To prove this

If 1 mile = 1.6,
Then,
3 miles = (1.6 x 3 ) which produce 4.8 km
0.75 mile = ( 0.75 x 1.6 ) equals to 1.2 km

4.8km + 1.2km = 6km , which proves that
3 miles + 0.75 mile = 6km
