Mike measured the stage where his band was going to play to determine if it is a right triangle. Does the stage with side lengths of 36 feet, 48 feet, and 60 feet form a right triangle

Answers

Answer:

let

hypotenuse[h]=60ft

base[b]=36ft

perpendicular [p]=48ft

by using Pythagoras law

p²+b²=h²

48²+36²=60²

2896≠3600

since p²+b²≠ h²[so the stage is not in a right angled triangle]but it is scalene triangle

Answer:

12cm squared

Step-by-step explanation:

The area of a triangle is 1/2bh

A = 1/2 x 4 x 6

A = 4 x 3

A = 12 cm squared

Answer:

The answer is B: 12 cm^2.

Step-by-step explanation:

The formula for the area of a triangle is b * h / 2 (base times height divided by two).

6 * 4 = 24

24 / 2 = 12

And since we're looking for area, the answer would be squared, as all areas are.

The answer: 12 cm^2.

If the value of x for normal distribution is 35, the mean of normal distribution is 65 and the standard deviation is 25, then calculate the standardized random variable, and P(X < 35).

Answers

Answer:

[tex]Z=-1.2[/tex]

Step-by-step explanation:

From the question we are told that:

Normal distribution [tex]x=35[/tex]

Mean of normal distribution [tex]\=x=65[/tex]

Standard normal distribution deviation [tex]\sigma= 25[/tex]

Generally the equation for standardized value is mathematically given by

 [tex]Z=\frac{x-\=x}{\sigma}[/tex]

 [tex]Z=\frac{35-65}{25}[/tex]

 [tex]Z=\frac{35-65}{25}[/tex]

 [tex]Z=-1.2[/tex]

Therefore the standardized value of x is

 [tex]Z=-1.2[/tex]
