Rotating a figure 90° counterclockwise about the origin results in an ordered pair (x, y) mapping to its image (-y, x). Thus point C, which is at (3, 5), will map to (-5, 3).

Point E is located at (−1, 6) and point F is located at (3, 9)

Mars2501 [29]

Answer:

$(x,y)=(\frac{7}{5},\frac{39}{5})$

Step-by-step explanation:

We have given:

E is (-1,6) and F is (3,9)

And ratios are 3:2

We will use the section formula to find the required coordinates:

section formula= $(\frac{m_1x_2+m_2x_1}{m_1+m_2},\frac{m_1y_2+m_2y_1}{m_1+m_2})$

Here, $m_1=3,m_2=2,x_1=-1,x_2=3,y_1=6,y_2=9$

On substituting the values in the formula we get:

$(x,y)=(\frac{3\cdot 3+2\cdot (-1)}{3+2},\frac{3\cdot 9+2\cdot 6}{3+2})$

$\Rightarrow (x,y)=(\frac{9-2}{5},\frac{27+12}{5}$

$\Rightarrow (x,y)=(\frac{7}{5},\frac{39}{5})$

Hence, required coordinates are: $(x,y)=(\frac{7}{5},\frac{39}{5})$

Find the number z such that the proportion of observations that are less than z in a standard Normal distribution is 0.5414. (b)

Akimi4 [234]

Answer:

Part (a) The value of Z is 0.10396. Part (b) The value of Z is 0.410008.

Step-by-step explanation:

Consider the provided information.

Part (a)

In order to find the number z such that the proportion of observations that are less than z in a standard Normal distribution is 0.5414, simply find 0.5414 in the table and search for the appropriate Z-value.

Now, observing the table it can be concluded that the value of Z is 0.10396.

Part (b)

Consider the number 65.91%

The above number can be written as 0.6591.

Now, find 0.6591 in the table and search for the appropriate Z-value.

By, observing the table it can be concluded that the value of Z is 0.410008.
