Sometimes; An equation can have infinitely many, two, one, or none, so that eliminates never and always.
Answer:
50% for pen
80% for homework
30% for both
(I don't know how they got 30% for both because it should be 40%.)
By the empirical rule, 95% of the distribution is within 2 standard deviations. Since the other 5% is split equally between the two tails of the distribution, the empirical rule says 2.5% will be below -2 standard deviations from the mean.
... 266 days - 2×(16 days) = 234 days
The shortest 2.5% of pregnancies last less than 234 days.
Answer:
-6
Step-by-step explanation:
to find slope by counting you just count rise over run
to get from (1,-4) to (0,2) you must go up 6 and back 1

Answer:
d: 4 r:5
Step-by-step explanation:
for domain the x coordinates doesn't go over -2 on the left or 2 on the right so if u add the units of the space in between it's 4 since 2- (-2)=4
for the range, the y coordinates never goes over 3 or -2 so range is 5 is u add the units in between
I hope that makes sense!
