Answer:
Let x = the number
2(x-5) = 9
2x - 10 = 9
2x = 19
x = 9.5
Step-by-step explanation:
More then 2 thats the only answer I can give
The number of defective modems in the inventory is 20%⋅ 30 + 8%⋅ 50 = 10 (out of 80).
Note that the number of defectives in the inventory is fixed, i.e., we are not told that there
is 1
8 probability that a modem in the inventory is defective, but rather that exactly 1
8
of
all modems are defective. The probability that exactly two modems in a random sample
of five are defective is = 0.102
Complementary angles add up to 90 so
angle + 47 = 90
angle = 90 - 47
angle = 43 so A
I used the completing the square method to get the (x+2)^2. The final line is in standard form.
