Answer:

False

Step-by-step explanation:

The graph of y = x² has it's vertex at (0, 0 ) ← Parent function

Here the vertex is at (0, - 2) ← not the parent function

The graph of x² has been shifted 2 units vertically down and is denoted by

y = x² - 2

Find the z-scores that delineate the middle 96% of all values from the others. enter your answers to 2 or 3 decimal places. from

scZoUnD [109]

The z-score that delineates the middle 96% of all vallues from others is obtained as follows.

$100(1-\alpha)\%=96\% \\ \\ 1-\alpha=0.96 \\ \\ \alpha=1-0.96=0.04 \\ \\ \alpha/2=0.04\2=0.02 \\ \\ z_{0.02}=2.054$

Therefore, <span>the z-scores that delineate the middle 96% of all values from the others</span> is 2.05

The period 7 (in seconds) of a pendulum is given by T = 2pi√( L divided by 32) where L stands for the length (in feet) of the pe

Answer:

128 feet

Step-by-step explanation:

$t = 2\pi \sqrt{\frac{l}{32} }$

So now we will substitute the values of T and π into the equation.

$12.56 = 2 \times 3.14 \sqrt{ \frac{l}{32} }$

$12.56 = 6.28 \sqrt{ \frac{l}{32} }$

Divide both sides by 6.28

$2 = \sqrt{ \frac{l}{32} }$

Square both sides.

$4 = \frac{l}{32}$

Multiply both sides by 32

$l = 4 \times 32 \\ l = 128 \: feets$

Need help here plz I don't know the how to do it thanks

ABD is the supplement of DBC, so it is equal to 180-130= 50 degrees.

If BE is the bisector, then it splits the angle in half evenly. 50/2=25 degrees for EBA and DBE each.

Final answer: 25 degrees
