For first question, What is approximate value of "......" this part is missing so please write whose approximate value question is asking to find
For second question we have to find
In right triangle ABC as show in attachment,
----(1)
Now AB is given by distance of point A from x axis which will be given by its y - coordinate. So
Similarly BC is the distance of point A from y axis (horizontal distance ) and that will be given by x coordinate of A. So
Plug these values in equation (1)
To divide fractions we flip (reciprocal ) bottom fraction and multiply it to top fraction as shown
Now 2 in top and bottom cancels out so we are left with
so thats the final answer for
Answer:
Residual = -2
The negative residual value indicates that the data point lies below the regression line.
Step-by-step explanation:
We are given a linear regression model that relates daily high temperature, in degrees Fahrenheit and number of lemonade cups sold.
Where y is the number of cups sold and x is the daily temperature in Fahrenheit.
Residual value:
A residual value basically shows the position of a data point with respect to the regression line.
A residual value of 0 is desired which means that the regression line best fits the data.
The Residual value is calculated by
Residual = Observed value - Predicted value
The predicted value of number of lemonade cups is obtained as
So the predicted value of number of lemonade cups is 23 and the observed value is 21 so the residual value is
Residual = Observed value - Predicted value
Residual = 21 - 23
Residual = -2
The negative residual value indicates that the data point lies below the regression line.
6 5/12 hey check out this website called calculator soup and it’ll give you the answer as well as show you how to solve it
22 * 100/11 = 200
<span>22 is 11% of 200</span>
These ratios are not proportional.
Explanation:
If the ratio 8:32 were simplified, it would equal 1:4 because they can both be divided by 8. But since 16 x 4 does not equal 72, they cannot be divided by 4 to make a simplified ratio such as the first example.
Hope I helped, and good luck!
