Answer:
110 degrees. Hope this is correct.
3(3x - 8) + 4x = -2(12 - 7x) - x
9x - 24 + 4x = -24 + 14x - x <em>distributed 3 on the left and -2 on the right</em>
- 24 + 13x = -24 + 13x <em>added like terms on the left and the right</em>
<u> -13x</u> <u> -13x </u>
-24 = -24
TRUE
A true statement means infinitely many solutions (aka All Real Numbers)
Answer: C
Answer:
8x4=32 or 8×4
Step-by-step explanation:
it's 32 because you are asking 8 time as many as 4 which is 8x4 or 8x4=3
Answer:
Probability both are nervous around strangers = 0.0049
Probability at least one is nervous around strangers = 0.1302
Step-by-step explanation:
Let probability a person selected in the population is nervous around strangers = P
P = 7%
P =
P = 0.07
Let probability a person selected in the population is not nervous around strangers = P'
P' = 1 - P
P' = 1 - 0.07
P' = 0.93
(i) probability of the first person selected is nervous around strangers = P
probability of the second person selected is nervous around strangers = P
Probability both are nervous around strangers = (P × P)
= 0.07 × 0.07
= 0.0049
(ii) Probability at least one is nervous around strangers = ( probability the first person is nervous around strangers AND the second person is not nervous around strangers ) OR ( probability the second person is nervous around strangers AND the first person is not nervous around strangers)
This implies,
Probability at least one is nervous around strangers = (P × P') or (P × P')
= (0.07 × 0.93) + (0.07 × 0.93)
= 0.0651 + 0.0651
= 0.1302
