Which shows the image of RST after the rotation (x, y) (y, -x)

Wittaler [7]

Answer:

Option A shows the image of RST after the rotation

Step-by-step explanation:

Coordinates of S=(1,3)

Coordinates of R = (-2,1)

Coordinates of T = (-1,7)

We are given that after rotation(x,y)→(y,-x)

So, The new coordinates after rotation will be :

Coordinates of S'=(3,-1)

Coordinates of R'= (1,2)

Coordinates of T'= (7,1)

These are the coordinates of triangle of Option A

So, Option A is true .

Hence Option A shows the image of RST after the rotation

The mean of a data set of 6 numbers is 8. The mean of a different data set of 6 numbers is 20. Whats the mean of the combined da

Aleksandr [31]

HERE IS YOUR ANSWER HOOMAN:

STEP BY STEP EXPLANATION FAM:

We have a set of four numbers and the mean is 5. We can see that the sum of the values is 20:

$\frac{20}{4}$ =5

We have another set of three numbers whose mean is 12. We can write that as:

$\frac{36}{3}$ =12

To find the mean of the seven numbers together, we can add the values together and divide by 7:

$\frac{20+36}{7}$ = $\frac{56}{7}$ =8

The amount of time it takes Isabella to wait for the bus is continuous and uniformly distributed between 3 minutes and 17 minute

Arturiano [62]

Answer:

P(X>5) = 0.857

Step-by-step explanation:

Let X $\sim$ uniform(3.17)

$f(x) = \dfrac{1}{17-3} ; \ \ \ 3 \le x \le 17$

The required probability that it will take Isabella more than 5 minutes to wait for the bus can be computed as:

$P(X > 5) = \int ^{17}_{5} f(x) \ dx$

$P(X > 5) = \int ^{17}_{5} \dfrac{1}{17-3} \ dx$

$P(X > 5) =\dfrac{1}{14} \Big [x \Big ] ^{17}_{5}$

$P(X > 5) =\dfrac{1}{14} [17-5]$

$P(X > 5) =\dfrac{12}{14}$

P(X>5) = 0.857
