Answer:

10.63.

Step-by-step explanation:

First we need to understand pythagorean theorem that is,

Hypotenuse^2=perpendicular^2+base^2.

=7^2+8^2.

=49+64

=113.

Hypotenuse^2=113.

Square root both sides.

Hypotenuse=10.63.

A plot of land is in the shape of a triangle. If one side is x meters, a second side is

Rudiy27

First side is = x
Second side is = 3x-3
Third side is = 44x - 66

Perimeter = Sum of sides
P = x + 3x + 44x -66 -3
P = 48x - 69

A manufacturing firm tests job applicants. Test scores are normally distributed with a mean of 500 and a standard deviation of 5

Blababa [14]

Answer:

The probability that the candidate score is 600 or greater

P(X≥ 600 ) = 0.0228

Step-by-step explanation:

Step(i):-

Given mean of the Population = 500

Given standard deviation of the Population = 50

Let 'X' be the random variable in normal distribution

Given X = 600

$Z = \frac{x-mean}{S.D} = \frac{600-500}{50} = \frac{100}{50} =2$

Step(ii):-

The probability that the candidate score is 600 or greater

P(X≥ 600 ) = P(z≥2)

= 0.5 - A(2)

= 0.5 -0.4772

= 0.0228

Final answer:-

The probability that the candidate score is 600 or greater

P(X≥ 600 ) = 0.0228
