To approximate the P(x<27) we need to find the z-score of the data, this will be given by:
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
x=27, μ=32, σ=4
z=(27-32)/4
z=-5/4
z=-1.25
thus
P(x<27)=P(z<-1.25)
=0.1056
=10.56%

Answer: 10.56%

Answer:

14/1.8 = x/4

Step-by-step explanation:

Using similar triangles,

height of man/length of man's shadow = height of tree/length of tree's shadow

1.8/4 = x/14

x/14 = 1.8/4

If we cross-multiply, we have

1.8 × 14 = x × 4

dividing both sides by 4 and 1.8,we have

14/4 = x/1.8

x/1.8 = 14/4

So, the two expressions we have are

x/14 = 1.8/4 and x/1.8 = 14/4.

So, the answer is 14/1.8 = x/4 since the product 1.8 × 14 = x × 4 cannot be expressed in the given ratio.

What is the first step in solving the quadratic equation x2 = 9/16

anygoal [31]

The equation is $\displaystyle{ x^2= \frac{9}{16}$ . We can rewrite the equation as:

$\displaystyle{ x^2= (\frac{3}{4})^2$ .

Our next step here is to take the square root of both sides, remembering that $\sqrt{x^2}=|x|$ .

Thus, we have $\displaystyle{ |x|= \frac{3}{4}$ . Our final step is solving the absolute value equation, which yields:

$\displaystyle{ x= \frac{3}{4}$ or $\displaystyle{ x= -\frac{3}{4}$ .

Solution set: { $-\frac{3}{4}, \frac{3}{4}$ }
