Explanation has been given below
Step-by-step explanation:
hope fully it may concern with 70% adults then
p = 0.77
randomly select = 6
then mean will be
mean = n * p = 6*0.77=4.62
To get variance np (1-p)
then putting values we get
np (1-p) = 4.62 *0.23 = 1.0626
taking square root we get
sd = 1.03
Most samples of 6 adults would differ from the mean by no more than 1 sd
mean is differ by no more than 2 sds .
In a real-life situation, it is expected that 4 or 5 of 6 to think it is a problem.
I would not expect 0, 1, or 2.

ANSWER: 384
Answer:
x < -7
Step-by-step explanation:
An inequality is solved similar to an equation with the exception that when multiplying or dividing by a negative coefficient, the sign must flip in the other direction. The original inequality is:
-6x > 42
To solve, you need to divide both sides of the inequality by -6, however, since you are dividing by a negative coefficient, the sign need to flip the other way:
-6x/-6 > 42/-6 = x < -7
A) Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
P= 3x^2/6x—1
The matrix represents
-3x + 5y = 15
2x + 3y = -10
