Point P is located at (−2, 7), and point R is located at (1, 0). Find the y value for the point Q that is located two over three

otez555 [7]

Answer:

$y_Q=\dfrac{21}{5}=4.2$

Step-by-step explanation:

If the point Q that is located two over three the distance from point P to point R, then PQ:QR=2:3.

Use formula to find the coordinates of the point Q:

$x_Q=\dfrac{3x_P+2x_R}{3+2}\\ \\y_Q=\dfrac{3y_P+2y_R}{3+2}$

In your case, P(-2,7) and R(1,0), then

$x_Q=\dfrac{3\cdot (-2)+2\cdot 1}{3+2}=\dfrac{-4}{5}\\ \\y_Q=\dfrac{3\cdot 7+2\cdot 0}{3+2}=\dfrac{21}{5}$

During an experiment, a spinner landed on green 9 times, which resulted in an experimental probability of StartFraction 1 over 6

ANTONII [103]

Answer:

Mary is incorrect

Step-by-step explanation:

We are given the following in the question:

Number of times the spinner landed on green color = 9

P(Green) =

$\dfrac{1}{6}$

Mary claimed that there must be 45 trials.

$\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

P(Green) =

$\dfrac{\text{Number of times spinner landed on green}}{\text{Total number of trials}}\\\\\Rightarrow \dfrac{9}{x}=\dfrac{1}{6}\\\\\Rightarrow x = 9\times 6 = 54$

There are 54 trials in the experiment and not 45 trials. Thus, Mary is incorrect.
