So percent means parts out of 100
x%=x/100
so we jsut have to find
(red)/(total)
add 23+52+34343434+61+30=34343600
red=52
52/34343600
divide out
0.0000015141103/1
multiply by 100/100
0.00015141103/100=0.00015%
make bottom number 100
26/100=26%
answer is 26%
Answer:
The cutoff rate that would separate the highest 2.5% of currency A/currency B rates is 1.92.
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 = 1.832
Standard deviation = 0.044
Top 2.5%
95% of the measures are within 2 standard deviation of the mean.
Since the normal distribution is symmetric, this 95% goes from the 50 - 95/2 = 2.5th percentile to the 50 + 95/2 = 97.5th percentile.
The 97.5th percentile is the cutoff for the highest 2.5% of currency A/currency B rates, and it is 2 standard deviations above the mean.
1.832 + 2*0.044 = 1.92
The cutoff rate that would separate the highest 2.5% of currency A/currency B rates is 1.92.
Answer:
A) No, because the greatest common factor is 8y?, and the completely factored form is 8y2(4y2 - 6y + 3).
Step-by-step explanation:
Considering the expression
4y(8y3 – 12y2 + 6y)
From the elements in the parenthesis, 2 and y can still be factored out such that what will be left of each element
8y3/2y = 4y2
12y2/2y = 6y
6y/2y = 3
Hence
4y(8y3 – 12y2 + 6y) = 4y*2y(4y2 - 6y +3)
= 8y2(4y2 - 6y + 3)
Answer:
Step-by-step explanation:
I'm going to assume the last part means to say 64 minutes for 9 kilometers
Let's treat these like points on a graph. You'll only really be able to tell time from distance if they are in a linear relationship, so let' check that. We are gonna take the slope between each point and if they are the same it's a linear relation.
Of course slope is (y2-y1)/(x2-x1)
(52-40)/(7-5) = 6
(64-52)/(9-7) = 6
(64-40)/(9-5) = 6
Didn't need to check the slope between the third and first since the slope between the first and second as well as the second and third were the same but figured I would to show. Anyway, the same slope means it is linear so we can solve the question.
Easiest way is probably to make an equation and then solve. to make an equation you use the formula y - y1 = m(x - x1) where (x1, y1) are one of the points you were given and m is the slope, which we found to be 6. So let's use (5,40) as our point. Also 5 has to be x and 40 has to be y since that's what we used for the slope formula above. Could easily have sqapped the two before though.
y - y1 = m(x - x1)
y - 40 = 6(x - 5)
y = 6x - 30 + 40
y = 6x + 10
So now we can just plug in to find a distance or a time. Again x is distance and y is time. We have distance so we plug that in.
y = 6(1) + 10
y = 6 + 10
y = 16
So that means it takes 16 minutes to go 1 kilometer.
Let me know if this didn't help.

False
Step-by-step explanation:
Because Americans colonized their land and forced them to live on "amazing" reservations. (They aren't as amazing as you would think)
