Answer:
c = 9
Step-by-step explanation:
You're looking for a number so that when you use that number in place of x, you end up with 20.
f(x) = 3x - 7
f(c) = 3c - 7
20 = 3c - 7
Add 7
27 = 3c
Divide by 3
9 = c
3 blue, 2 red, 5 white........total of 10 sweaters
probability that red is picked first : 2/10 reduces to 1/5
replace
probability of second pick being white : 5/10 reduces to 1/2
replace
probability of third pick being blue : 3/10
probability of all of this happening : 1/5 * 1/2 * 3/10 = 3/100 <==
Answer:
The population is 34,000. The sample is 2,000
Step-by-step explanation:
Population in statistics can be explained as the group or set of all elements which are of particular interest to a researcher or a study. In the scenario above, the research interest concerns customers who pay with a debit card, whose number amounts to 34,000, this value refers to the population. The sample is referred to as the subset of the population or larger sample, the sample from the study corresponds to number of debit card users who were selected at random to participate in the survey. This value is 2000.
Answer:
D) y=-1/2x+4
Step-by-step explanation:
D) y=-1/2x+4
In order to be parallel, it has to have the same slope (-1/2). Also, if you plug in (-2,5) for x and y, it does pass through those coordinates.
Answer:
(4)
Step-by-step explanation:
As the circumference of a circle measures 360 degrees, minor arc AC measures 360-268=92 degrees.
By the inscribed angle theorem, angle ABC measures 46 degrees.
