Need on last one 30 points mrs. jones teaches an 8th grade math class in texas. she wants to find out if 8th graders in texas prefer cola or juice, so she polls her thirty 8th grade students. she finds out the most of them prefer cola over juice. identify the population, sample, what method of sampling mrs. jones used, and if there was any bias in the sample.

Population = all Texas 8th graders
Sample = Mrs. Jones's thirty 8th graders
Sampling method = convenience sampling

Yes, there was a sampling bias. Since the complete sample was from the same school and class, it does not represent the total population of Texas 8th graders very well.

Hoped this helped :D

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
