Answer:

Use the equation of the IQ-GPA trend line to find the IQ corresponding to the given GPA.

Use the equation of the IQ-SAT trend line to find the SAT corresponding to that IQ.

First, use the equation of the trend line to find the IQ that is expected by the GPA. Next, use the other equation of the trend line to find the SAT that is predicted by the IQ.

After a storm, 135 trees out of 180 were left standing. What is the percentage loss of the number of trees?

beks73 [17]

Answer:

Percentage loss of the number of trees is $25\%$ .

Step-by-step explanation:

Given: After a storm, $135$ trees out of $180$ were left standing.

To find: What is the percentage loss of the number of trees?

Solution:

We have,

Total number of trees $=180$

Number of trees left standing $=135$

Therefore, loss of trees $=180-135=45$

We now that $\text {Loss\%}=\frac{\text{Number of trees left}}{\text{Total number of trees}}\times 100 \%$

$\implies \text {Loss\%}=\frac{45}{180}\times 100 \%$

$\implies \text {Loss\%}=\frac{450}{18} \%$

$\implies \text {Loss\%}=25 \%$

Hence, the percentage loss of the number of trees is $25\%$ .

Write an equation of four lines that intersect to form the sides of a parallelogram

horrorfan [7]

The question requires that the four lines that intersect form a parallelogram but not an specific parallelogram, so you are not restricted by a diagram.

You can use these equations for the four lines:

1) y = 0 (it is the x-axis)

2) y = 4 (it is a line parallel to the x-axis, whose y-intercept is 4.

3) y = x (it is an inclined line that intersects both y = 0 and y = 4 lines.

4) y = x + 7 (it is a line parallel to y = x, that also intersect the both y = 0 and y = 4 lines.
