As you said in the beginning pizza now is quarter mile away from Calvin`s, so this means pizza now is STILL quarter miles from Calvin`s house. And since his house is the midpoint so you must multiply 1/4 mile by 2 to get a product of 2/4 or 1/2 miles apart!!
(0.1x + 0.4y)^2 =
(0.1x + 0.4y)(0.1x + 0.4y)
FOIL method
F (first)...multiply the first terms in each set....0.1x * 0.1x = 0.01x^2
O (outside)...multiply outside terms in each set...0.1x * 0.4y = 0.04xy
I (inside)...multiply inside terms in each set....0.4y * 0.1x = 0.04xy
L (last)...multiply last terms in each set...0.4y * 0.4y = 0.16y^2
now we have : 0.01x^2 + 0.04xy + 0.04xy + 0.16y^2....combine like terms
0.01x^2 + 0.08xy + 0.16y^2 <===
Answer:
(B) Because the confidence interval includes 0, we don't have convincing evidence that sugar causes faster reading times, on average.
Step-by-step explanation:
Confidence Interval for the population mean difference in reading is basically an interval of range of values where the true population mean difference in reading time can be found with a certain level of confidence.
Mathematically,
Confidence Interval = (Sample mean) ± (Margin of error)
In using confidence interval of population mean difference in reading times for hypothesis testing, if the interval obtained contains a value of 0, it means the population mean difference in reading times can take on a value of 0 and indicate that there isn't enough evidence to conclude that there is a significant difference in the two quantities being compared. (The null hypothesis is true).
If the interval doesn't contain a 0, then it can be concluded that there is enough evidence to conclude that there is significant difference in the two quantities being compared.
Hope this Helps!!!
Answer:
These numbers are all multiples of 3.
Step-by-step explanation:
1 is a multiple of every number.
3 is a multiple of 3 because of 3 x 1
6 is a multiple of 3 because of 3 x 2
If you have any questions please feel free to ask in the comments.
12 3/4 + 15 1/4
12 + 15 = 27
3/4 + 1/4 = 4/4 or the same as 1
27+1=28
So the answer is Julie used 28 gallons of Water.
This problem has my name!!!!!!!!!!!!!
