Answer:

A. it is 90 degrees counterclockwise on the origin.

Step-by-step explanation:

The shape was moved in the opposite direction a clock will move so it is counterclockwise.

You had the origin part right though.

A. it is 90 degrees counterclockwise on the origin.

Decide !!!!!!!!!!!!!!!!!!

Savatey [412]

Make note of the coefficients in the first and fourth equations. They've been conveniently picked so that subtracting one equation from the other eliminates every variable but t. We have

(3r + 2s + t + 2u + 3v) - (3r + 2s + 3t + 2u + 3v) = 7 - 17

-2t = -10

t = 5

Two resistors, with resistances R1 and R2, are connected in series. R1 is normally distributed with mean 100 ohms and standard d

puteri [66]

Answer:

The probability that R2 is bigger than R1 is P=0.9633.

Step-by-step explanation:

We need to compute the probability that R2 is bigger than R1:

$P(R_2>R_1)$

To do this, we define a new variable Das the difference between the two resistances:

$D=R_2-R_1$

Then,

$P(R_2>R_1)=P(R_2-R_1>0)=P(D>0)$

As R1 and R2 are normal random variables, the properties of D are:

$\mu_D=\mu_{R2}-\mu_{R1}=120-100=20\\\\\sigma_D=\sqrt{\sigma_{R2}^2+\sigma_{R1}^2}=\sqrt{10^2+5^2}=\sqrt{100+25}=\sqrt{125}=11.18$

Then, we can calculate the z-value for D=0

$z=\frac{x-\mu}{\sigma} =\frac{0-20}{11.18}=\frac{-20}{11.18}= -1.79$

$P(D>0)=P(z>-1.79)=0.9633$

If APORASTU, what is the scale factor of APOR to ASTU? Ο Α. 5 Ο Ο Ο Β. 4 G. D

forsale [732]

Answer:

Step-by-step explanation:

The scale factor is the ratio of corresponding sides, image to original

scale factor = $\frac{TU}{QR}$ = $\frac{4}{20}$ = $\frac{1}{5}$ → C
