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).
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]

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
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
Work out the length of x.

8. Which choice is chord?
LG
CH
LM
CJ
Answer:
Step-by-step explanation:
LG: is a chord. Are there others?
CH: is a radius. C is the center of the circle.
LM: You have to draw in LM. LM would be a secant. It cuts the circle in exactly two places.
CJ: Anything coming from C and ending at the circumference is going to be a radius.

Step-by-step explanation:
A
π=89
π
Answer:
5.3
Step-by-step explanation:
The equation is A=πr²
The area is 89 so 89=πr²
89/π=r²
√89/π =r
r=5.322554

If f(x) = 2(3^x) + 1, what is the value of f(2)?
(1) 13
(3) 37
(2) 19
(4) 54
Answer:
Given
F ( x ) = 3 x 2 + 1 , to find F ( − 2 ) , we have to just put
x = − 2 in the formula for F ( x ) .
therefore , F ( − 2 ) = 3 ( − 2 ) 2 + 1 = 3 ( 4 ) + 1 = 13 .

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.

The equation of a line is y=mx+ 4. What is the value of m if the line passes through point (−3, 7)?
Answer:
m= -1
Step-by-step explanation:
plug in the coordinate (-3, 7) into y=mx+4 where (x, y)
7=-3m+4
solve for m and you get -1
:)
Answer:
[tex]\huge\boxed{m=-1}[/tex]
Step-by-step explanation:
We have
[tex]y=mx+4\\\\(-3,\ 7)[/tex]
Put the coordinates of the given point to the equation of the line:
[tex](-3,\ 7)\to x=-3,\ y=7\\\\7=-3m+4\qquad|\text{subtract 4 from both sides}\\\\7-4=-3m+4-4\\\\3=-3m\qquad|\text{divide both sides by (-3)}\\\\\dfrac{3}{-3}=\dfrac{-3m}{-3}\\\\-1=m\to m=-1[/tex]
