Answer:
You should buy a 12-pack of 12 oz cans for $4.75 rather than seven 20 oz bottles that are on sale for $0.90 because seven 20 oz bottles that are on sale for $0.90 cost $6.30 all together which means a 12-pack of 12 oz cans for $4.75 is cheaper than seven 20 oz bottles that are on sale for $0.90.
The total would be $4.68. It is $0.78 for 0.4 of a pound, and you multiply $1.95 two times aqnd add that to the $0.78
Answer:
1899
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 3234
Standard deviation = 871
Percentage of newborns who weighed between 1492 grams and 4976 grams:
1492 = 3234 - 2*871
So 1492 is two standard deviations below the mean.
4976 = 3234 + 2*871
So 4976 is two standard deviations above the mean.
By the Empirical Rule, 95% of newborns weighed between 1492 grams and 4976 grams.
Out of 1999:
0.95*1999 = 1899
So the answer is 1899
The answer is B: a^3b^4<span>
Proof:
Simplify the following:
(a^7 b^8)/(a^4 b^4)
Combine powers. (a^7 b^8)/(a^4 b^4) = a^(7 - 4) b^(8 - 4):
a^(7 - 4) b^(8 - 4)
7 - 4 = 3:
a^3 b^(8 - 4)
8 - 4 = 4:
Answer: a^3 b^4
PS: I just wish that you put the equation down as it's intended i.e.
a^7b^8/a^4b^4 is not the same as (<span>a^7b^8)/(a^4b^4)</span>
</span>
Answer:
y=1/2+12
Step-by-step explanation:
first you have to find the slope to the first equation and that is x/2 and then you have to use the point and plug all of that into slope intercept form(y=mx+b)
