Complete Question

The complete question is shown on the first uploaded image

Answer:

$P(X < 4) = 0.4141$

$P(4 < X < 6) = 0.32876$

$P(X >8) = 0.064037$

The correct option is B

Step-by-step explanation:

From the question we are told that

The mean is $\mu = 4.5$

The standard deviation is $\sigma = 2.3$

Generally the probability that a randomly selected study participant's response was less than 4 is mathematically represented as

$P(X < 4) = P(\frac{X - \mu }{\sigma} < \frac{4 - 4.5}{ 2.3} )$

$\frac{X -\mu}{\sigma} = Z (The \ standardized \ value \ of\ X )$

$P(X < 4) = P(Z < -0.217 )$

From the z-table $P(Z < -0.217 ) = 0.4141$

$P(X < 4) = 0.4141$

Generally the probability that a randomly selected study participant's response was between 4 and 6 is mathematically represented as

$P(4 < X < 6) = P( < \frac{4 - 4.5}{ 2.3} < \frac{X - \mu }{\sigma} < \frac{6 - 4.5}{2.3})$

=> $P(4 < X < 6) = P( \frac{4 - 4.5}{ 2.3} < \frac{X - \mu }{\sigma} < \frac{6 - 4.5}{2.3})$

=> $P(4 < X < 6) = P( -0.217 < Z< 0.6522$

=> $P(4 < X < 6) = (Z< 0.6522) -P( Z < -0.217)$

From the z-table

$(Z< 0.6522) = 0.74286$

$P(4 < X < 6) = 0.74286 -0.4141$

=> $P(4 < X < 6) = 0.74286 -0.4141$

=> $P(4 < X < 6) = 0.32876$

Generally the probability that a randomly selected study participant's response was more than 8 is mathematically represented as

$P(X > 8) = P(\frac{X - \mu }{\sigma} > \frac{8 - 4.5}{ 2.3} )$

$P(X > 8) = P(Z > 1.52174 )$

From the z-table $P(Z > 1.52174 ) = 0.064037$

$P(X >8) = 0.064037$

Decide whether 0 is a solution of the inequality: a.) 2x – 1 9 c.) x – 3 > 1

marin [14]

Step-by-step explanation:

How to check a solution: Just as you can check the solution to an equation, you can check a solution to an inequality. First, you check the end point by substituting it in the related equation. Then you check to see if the inequality is correct by substituting any other solution to see if it is one of the solutions.

How to tell if its true or false: An inequality is a statement that shows the relationship between two (or more) expressions with one of the following five signs: <, ≤, >, ≥, ≠. Like an equation, an inequality can be true or false. 34 - 12 > 5 + 2 is a true statement. 1 + 3 < 6 - 2 is a false statement.
