Answer:

x = (3/2)√2

Step-by-step explanation:

The ratio of side lengths of the isosceles right triangle is ...

1 : 1 : √2

That means the short side of that triangle will be 6/√2 = 3√2.

The lengths of the sides of a 30°-60°-90° triangle have the ratios ...

1 : √3 : 2

The long side is the short side of the isosceles right triangle, 3√2, and the short side of the 60° triangle is half that.

x = (3/2)√2

Answer:

Step-by-step explanation:

Hello,

The two triangles are similar and x is positive, different from 0, so we can write.

$\dfrac{x}{9}=\dfrac{12}{x}\\\\x^2=12\times 9\\\\ x = \sqrt{4\times 3 \times 9}=2\times 3 \times \sqrt{3}\\\\ \boxed{\sf \bf x=6\sqrt{3} }$

Thanks

5. 3g + 9 = 2. 3g + 15 Solve for G

Alik [6]

5.3g + 9 = 2.3g + 15
5.3g + 9 - 9 = 2.3g + 15 - 9
5.3g = 2.3g + 6
5.3g - 2.3g = 2.3g - 2.3g + 6
3g = 6
3g / 3 = 6 / 3
g = 2

A sleep time of 15.9 hours per day for a newborn baby is at the 10h percentile of the distribution of sleep times for all newbor

Nuetrik [128]

Answer:

option (D) 16.5

Step-by-step explanation:

Data provided:

Sleep time of , X = 15.9 is at the 10th percentile

Standard deviation, σ = 0.5 hour

also,

10th percentile of normal distribution is

Z = F⁻¹(0.10)

Z = - 1.28 (Using Standard Normal distribution)

Now,

$\\Z=\frac{X-\mu}{\sigma}$

X = μ + ( σ × Z )

μ = X - ( σ × Z )

on substituting the respective values, we get

μ = 15.9 - 0.5 × (-1.28)

μ = 16.5

Hence, the correct answer is option (D) 16.5
