Answer:correction so 1] y = 3x + 7
// Plug this in for variable y in equation [2]
[2] 5x + 2•(3x+7) = 3
[2] 11x = -11
// Solve equation [2] for the variable x
[2] 11x = - 11
[2] x = - 1
// By now we know this much :
x = -1
y = 3x+7
// Use the x value to solve for y
y = 3(-1)+7 = 4

Answer:
5% increase
Step-by-step explanation:
First, find how much it increased:
6300 - 6000
= 300
Then, to find the percent increase, divide 300 by 6000
300/6000
= 0.05
So, there was a 5% increase in the population
Answer:
Step-by-step explanation:
Hello!
We have the information of the average wind speed for three months:
February:
Mean: 2.324
SD: 1.577
Otlier: 6.73 mph
June:
Mean: 0.857
SD: 0.795
Otlier: 3.93 mph
August
Mean: 0.63
SD: 0.597
Outlier: 2.53mph
a)
Z= X - μ ~N(0;1)
δ
≅2.79
≅ 3.18
b)
Comparing the three Z-scores you can say that the strongest wind event was in June. The number obtained means that is the furthest one in relation to the mean.
Answer:
sorry don't know
Step-by-step explanation:
3 19/125
You can take any number, such as 3.152, and write a 1 as the denominator to make it a fraction and keep the same value, like this:
3.152 / 1
To get rid of the decimal point in the numerator, we count the numbers after the decimal in 3.152, and multiply the numerator and denominator by 10 if it is 1 number, 100 if it is 2 numbers, 1000 if it is 3 numbers, and so on.
Therefore, in this case we multiply the numerator and denominator by 1000 to get the following fraction:
3152 / 1000
Then, we need to divide the numerator and denominator by the greatest common divisor (GCD) to simplify the fraction.
The GCD of 3152 and 1000 is 8. When we divide the numerator and denominator by 8, we get the following:
394 / 125
Therefore, 3.152 as a fraction is as follows:
394 / 125
