Answer:

The answer is "0.869"

Step-by-step explanation:

Number of sample (n) = 84

Number of correct response (X) = 73

Calculating the Sample proportion:

Formula:

\text{Sample proportion}=\frac{\text{number of sample}}{\text{correct responses}}

                              =\frac{n}{X}\\\\= \frac{73}{84} \\\\=0.869

Could someone help me find the velocity of the object pls im stuck
Mila [183]

Answer:

10 m/s

Step-by-step explanation:

Velocity= Position/Time

You can take any point on the line to calculate velocity.

Lets take t=1s

At t=1, position=10m

velocity= 10m/1s

=10 m/s

You can take any other point too, velocity will remain same.

For eg.

At t=5s

position=50m

velocity=50/5

=10m/s

Hope it helps :-)

The end point P of a line segment PQ(-3,6) and its mid point is (5,8) Find the coordinates of the end point Q
Georgia [21]

Answer:

  • (13, 10)

Step-by-step explanation:

Let Q have coordinates x and y

<u>Using midpoint formula we find the values of x and y</u>

  • (- 3 + x)/2 = 5 ⇒ -3 + x = 10 ⇒ x = 10 + 3 ⇒ x = 13
  • (6 + y)/2 = 8 ⇒ 6 + y = 16 ⇒ y = 16 - 6 ⇒ y = 10
  • Q = (13, 10)
