Answer:
B. A two-sample t-interval for a difference between population means
Step-by-step explanation:
in the given situation we are comparing the groups that are independent also we test the difference of the population mean so here consider inference procedure for analyzing the results is that there should be two sample t -interval by taking a difference between the population means
hence, the correct option is B.
1.) Convert all measurements to meters:
2.5km * 1,000 = 2,500m ; .250km * 1,000 = 250m ; 2,500cm / 100 = 25m
25,000cm / 100 = 250m ; 250mm / 1,000 = .25m
2.) Compare the converted measurements. Therefore, the quantities that are equivalent to 250m are:
.250km ; 25,000cm
Answer:
A Fraction
Step-by-step explanation:
33/3 is a fraction because it consists of a numerator and a denominator.
Step-by-step explanation:
100% = 12 throws
what are 150% ?
so, the question really is, what do I need to multiply 100(%) with to get 150(%) ?
100×x = 150
x = 150/100 = 1.5
so, since 100% and 12 throws are equivalent, we need to multiply the number of throws with the same factor x :
12×1.5 = 18
so,
150% = 18 throws.
she made 18 throws.
These are both rational numbers, because they are (our could be written as) a fraction. 1.45 = 145/100
There is no smaller subset of real numbers that works, because the next smaller subset is integers, but these aren’t integers.
