B is the midpoint of line AC and E is the midpoint of line BD. If A(-9,-4), C(-1,6), and E(-4,-3) find the coordinates of D?

MakcuM [25]

Answer:

((-9 - 1)/2, (-4 + 6)/2) = (-5,1)

((-5 + x)/2, (1 + y)/2) = (-4,-3)

(-5 + x)/2 = -4

-5 + x = -8

x = -3

(1 + y)/2 = -3

1 + y = -6

y = -7

(-3,-7)

Among 9 electrical components exactly one is known not to function properly. If 3 components are randomly selected, find the pro

kozerog [31]

Answer:

P=0.66

Step-by-step explanation:

We know that Among 9 electrical components, exactly one is known not to function properly. If 3 components are randomly selected.

We calculate the probability that all selected components function properly.

We calculate the number of possible combinations:

$C_3^9=\frac{9!}{3!(9-3)!}=84$

We calculate the number of favorable combinations:

$C_3^8=\frac{8!}{3!(8-3)!}=56$

Therefore the probability is:

$P=\frac{56}{84}\\\\P=0.66$

Ratling [72]

Answer:

13 1/8

Step-by-step explanation:

3/8-(-51/4)

Subtracting a negative is like adding

3/8 + 51/4

get a common denominator

3/8+ 51/4 *2/2

3/8 + 102/8

105/8

8 goes into 105 13 times with 1 left over

13 1/8
