Answer:

Step-by-step explanation:

<h3>Let us assume the angle be xo Then it’s complement angle is 4x°.</h3><h3 /><h3>When the sum of two angles is 90°, then the angles are known as complementary angles. If two angles add up to form a </h3><h3>right angle, then these angles are referred to as complementary angles.</h3><h3 /><h3>4x + x = 90° </h3><h3 /><h3>5x = 90°</h3><h3 /><h3>x = 18° </h3><h3 /><h3>∴ The angle x = 18° and</h3><h3 /><h3>Its complement 4x = (4×18o) = 72°</h3><h3>Stay safe, stay healthy </h3><h3>and blessed</h3><h3>Have a good day !</h3><h3>Good luck for ur assignment.</h3><h2>Thank you</h2>

Allisa [31]

Answer:

Percentile 5

$z=-1.64$

And if we solve for a we got

$a=24.2 -1.64*2.6=19.94$

Percentile 95

$z=1.64$

And if we solve for a we got

$a=24.2 +1.64*2.6=28.46$

Step-by-step explanation:

Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:

$X \sim N(24.2,2.6)$

Where $\mu=24.2$ and $\sigma=2.6$

We want to find the percentiles 5 and 95 for this case.

Percentile 5

For this part we want to find a value a, such that we satisfy this condition:

$P(X>a)=0.95$ (a)

$P(X$ (b)

We want to find a percentile with 0.95 of the area on the left and 0.05 of the area on the right it's z=-1.64. On this case P(Z<-1.64)=0.05 and P(z>-1.64)=0.05

Using this condition we got:

$P(X$

$P(z$

Replacing we got:

$z=-1.64$

And if we solve for a we got

$a=24.2 -1.64*2.6=19.94$

Percentile 95

$z=1.64$

And if we solve for a we got

$a=24.2 +1.64*2.6=28.46$
