Step 1: Add together the known angles.
Step 2: Subtract the sum from 180°.
Answer:
Step-by-step explanation:
Given is a list of prices in dollars for one night at different hotels in a certain region
To find range, variance and std deviation.
Mean 155.75
Standard Error 23.80782434
Median 150
Mode #N/A
Standard Deviation 67.33869616
Sample Variance 4534.5
Kurtosis -1.593759971
Skewness 0.344624422
Range 172
Minimum 86
Maximum 258
Sum 1246
Count 8
Thus we find range = 172 $. This gives an idea about the lowest and highest difference.
Variance = Average of squares of deviations from the mean= 4533.329 $^2gives us an idea about the dispersion of data. This helps to have an idea about the price rise or low in different hotels
Std deviation is square root of variance 67.33 $ shows an idea about the dispersion and also coefficient of variation as a ratio of mean to std deviation.
Answer:
The answer that you are looking for is basically y = 7/6x + any number besides 4.
Step-by-step explanation:
So, two parallel lines are two lines that will never intersect. To have that, both of the lines have to have the same exact slope. But they cannot have the same y-intercept because that would change it from parallel to infinite solutions.
I hope that I helped.
the multiplied the 2 in 1/2 but not the whole thing and i would solve it like this
2 1/2 × 2 = 5
Answer:
$2000 was invested at 6% and $1000 was invested at 7%
Explanation:
Let:
x= the amount invested at 6% annual interest
y= the amount invested at 7% annual interest
The total amount invested was $3000. So,
x+y =3000
or
y=3000-x ===> Equation 1
Then, the total interest earned for the year was $190. So,
0.06x+0.07y=190 =====> Equation 2
Substitute y=3000-x into 0.06x+0.07y=190.
Substitute x=2000 into x+y =3000.
So,
Therefore, $2000 was invested at 6% and $1000 was invested at 7%.
