Answer:
a) z = 1.40
b) X is greater than or equal to 4.9
Step-by-step explanation:
Population mean (μ) = 1.54
Standard deviation (σ) = 2.40
The z-score for any given value X is:
a) For X= 4.9:
The corresponding z-score for x = 4.9 is z=1.40
b) Z-scores higher than 1.40 correspond to values of X higher than 4.9. Therefore, the area under the standard normal probability density function from z to infinity, P(z ≥ 1.40), is interpreted as the probability that X is greater than or equal to 4.9.
<em>Copying</em> a given <u>segment</u> is the process in which a given<em> line segment</em> is drawn following the required <u>steps</u> so that both <u>object</u> and <u>image</u> have the same length. Therefore,
i. PQ = 12 cm
ii. MN = 12 cm
Thus, PQ = MN
Construction is a process that requires the use of <u>materials</u> and <u>instruments</u> to produce a required <em>image</em>. This involves following stated or required steps.
A given <em>line segment </em>can be copied by following appropriate steps. Such that both <u>lines</u> would have the same <u>length</u>, and would be <u>parallel </u>to each other or as required.
The given question requires following the stated <em>steps</em> to produce the required <em>construction</em>. Such that <u>line</u> segment NM is the image of PQ, and both have equal <u>length</u>.
The required <u>construction</u> for the question is <u>attached</u> to this answer.
