Answer:

y=4

Step-by-step explanation:

<h3>The triangle is divided further into 2 right triangles. So ignore the left one.</h3><h3>We know the angle of elevation is 30° and the hypotenuse is 8.</h3><h3>Looking at SOH CAH TOA we use the sine ratio in trigonometry because we have to find the side opposite to the angle given and we know the hypotenuse. </h3><h3>It is: sin 30 = y/8</h3><h3>y= 8 sin 30</h3><h3>y=4</h3>

TotCo is developing a new deluxe baby bassinet. If the length of a newborn baby is normally distributed with a mean of 50 cm and

Delicious77 [7]

Answer:

<em>The interior length of the bassinet to ensure that 99 percent of newborn babies will fit = 1.7 cm</em>

Step-by-step explanation:

<u><em>Explanation:</em></u>-

<em><u>step(i):</u></em>-

Given mean of population = 50 cm

<em>standard deviation of Population = 5 cm</em>

<em>Given Margin of error = 10 cm</em>

<em>The Margin of error is determined by </em>

<em></em> $M.E = \frac{Z_{\alpha } S.D}{\sqrt{n} }$ <em></em>

<u><em>Step(ii)</em></u><em>:-</em>

<em>Given level of significance ∝ = 99 % or 1 %</em>

Z₀.₀₁ = 2.576

$10 = \frac{2.576 X 5}{\sqrt{n} }$

$\sqrt{n} = \frac{2.576 X 5}{10}$

√n = 1.3

squaring on both sides , we get

<em>n = 1.69≅ 1.7 cm</em>

<u><em> Final answer:</em></u>-

<em>The interior length of the bassinet to ensure that 99 percent of newborn babies will fit = 1.7 cm</em>
