30% of the over 30s are female.
Work out how many of the over 30s are male.
Submit Answer
males over 30
Step-by-step explanation:
600 people is the total number of people.
with a given ratio of 4:1 we know that this total number of people is basically split into 5 (4 + 1) equal units.
each of the 5 units is therefore
600 / 5 = 120 people.
the "over 30s" are 4 of these units = 4 × 120 = 480 people.
the "30 and under" are 1 unit = 120 people.
30% of these 480 "over 30" people are female.
that leaves under normal circumstances 100 - 30 = 70% of these 480 "over 30" people to be male.
100% = 480
1% = 100%/100 = 480/100 = 4.8
70% = 1% × 70 = 4.8×70 = 48×7 = 336 people.
there are 336 males over 30 on that ship.
B) y = 4x + 11
C) y = 4x + 7
D) y = 4x - 7
Answer:
The answer is the option B
Step-by-step explanation:
we know that
The equation of the line into slope point form is equal to
in this problem we have
substitute
---> equation of the line into slope point form
isolate the variable y
---> equation of the line into slope intercept form
Answer: B) y = 4x + 11
