Answer:

(-3, 5.5)

Step-by-step explanation:

To find the midpoint, you add up the corresponding coordinates (x with x and y with y) and divide each by 2.

(-7+1)/2 = -3

(8+3)/2 = 5.5

Write the first five terms of the geometric sequence in which a1=8 and the common ratio is -1/2.
Oliga [24]

Answer:

First five terms are:

8 , (-4) , 2 , (-1) , (1/2)

Step-by-step explanation:

a_{1}=8 \\\\r = \frac{-1}{2}\\\\a_{2}=\frac{-1}{2}*a_{1}= \frac{-1}{2}*8= -4\\\\a_{3}=\frac{-1}{2}*a_{2}=\frac{-1}{2}*-4=2\\\\a_{4}=\frac{-1}{2}*a_{3}=\frac{-1}{2}*2=-1\\\\a_{5}=\frac{-1}{2}*a_{4}=\frac{-1}{2}*-1=\frac{1}{2}

70% of Ms. Miller's class passed the test on the first try. Those who failed were able to retake and half of those students pass
MrRissso [65]

Answer:

85%

Step-by-step explanation:

  1. Calculate how many students passed on their first try. 20 x 70% is 14, so 14 students passed on their first try.
  2. 6 students retook the test. Half of 6 is 3. Add 3 to the 14 students that passed earlier.
  3. Calculate the percent with the equation 17/20 = 0.85. 0.85 = 85%.
