I’m another normally distributed test score is 80 and the standard deviations is 10. How common are values in the less than 60?
lord [1]

Answer:

<em>The probability of obtaining a score less than 60 is 2.28% </em>

<em>It happens 2 out of 100 times.</em>

Step-by-step explanation:

If the mean μ = 80 and the standard deviation σ = 10, then we need to find the probability that an X value is less than 60.

Then we find

P(X

To find this probability we use the Z statistic.

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

P(\frac{X- \mu}{\sigma}

P(Z

This is the same as

P(Z> 2)

We look for this value in the table for the normal distribution of right queue and we have:

P(X  2) = 0.02275

<em>The probability of obtaining a score less than 60 is 2.28% </em>

<em>It happens 2 out of 100 times.</em>

The edge length of a cube is 17 cm. Identify the length of its diagonal. Round to the nearest tenth, if necessary. HELP PLEASE!!
lara31 [8.8K]

Answer:

29.4 cm

Step-by-step explanation:

The length of the space diagonal can be found to be the root of the squares of the three orthogonal edge lengths. For a cube, those edge lengths are all the same, so the diagonal length is ...

d = √(17^2 + 17^2 +17^2) = 17√3 ≈ 29.4 . . . . cm

_____

Consider a rectangular prism with edge lengths a, b, c. Then the face diagonal of the face perpendicular to edge "a" has length ...

(face diagonal)^2 = (b^2 +c^2)

and the space diagonal has length ...

(space diagonal)^2 = a^2 + (face diagonal)^2 = a^2 +b^2 +c^2

So, the length of the space diagonal is ...

space diagonal = √(a^2 +b^2 +c^2)

when the prism is a cube, these are all the same (a=b=c). This is the formula we used above.
