I’m the triangle shown below what is the approximate value of x

Dafna1 [17]

Answer:

The answer is choice B: 22.52 units.

Step-by-step explanation:

We use the Pythagoras's theorem which says for a right triangle with sides $x,y$ and hypotenuse $z$ :

$x^2+y^2=z^2.$

In our case

$z=26$

$y=13$

So we solve for $x:$

$x=\sqrt{z^2-y^2}=\sqrt{26^2-13^2} =\boxed{22.52\: units.}$

Which is choice B.

padilas [110]

Answer: 0.60

Step-by-step explanation:

Given: Mean : $\mu = 22\text{ minutes}$

Standard deviation : $\sigma = 8\text{ minutes}$

The formula to calculate z is given by :-

$z=\dfrac{x-\mu}{\sigma}$

For x= 20 minutes

$z=\dfrac{22-20}{8}=0.25$

The P Value = $P(z$

Hence, the probability that a randomly selected shopper will spend less than 20 minutes in the store= 0.60
