if a sample size 40 is drawn from the population that has mean 276 and a variance of 81, what is the probability that the mean of the sample will be less than 273?
Answer:
The probability is 0.017429
Step-by-step explanation:
We start by calculating the z-score
Mathematically;
z-score = (x-mean)/SD/√n
In this case;
x = 273
mean = 276
SD = √(variance) = √81 = 9
n = 40
Substituting these values into the z-score formula, we have that;
z = (273-276)/9/√40
z = -2.11
So we proceed to get the probability
the probability in this case is;
P( z < -2.11)
We can use the normal distribution table for this
Our answer will be
P( z < -2.11) = 0.017429

> AA.3 Area of triangles and trapezoids ENE(IXL)
What is the area?
5 yd
8 yd
square yards
(click the photo)
also could someone explain how you get the area of these?!?
Answer:
Area of triangle = 20 square yards
Step-by-step explanation:
The height of triangle = 5 yd
The base of triangle = 8 yd
We need to find area of triangle.
The formula used is: [tex]Area\: of\: triangle=\frac{1}{2}\times base \times height[/tex]
Putting values and finding area
[tex]Area\: of\: triangle=\frac{1}{2}\times base \times height\\Area\: of\: triangle=\frac{1}{2}\times 8 \times 5\\Area\: of\: triangle=4 \times 5\\Area\: of\: triangle=20\:square\:yards[/tex]
So, Area of triangle = 20 square yards
IS 7 7 Solve for a = √[? [] a a = 4 Enter the number that goes beneath the radical symbol 4 Enter
Answer:
[tex]a=\sqrt{33}[/tex]
Step-by-step explanation:
When we solve for this we should always remember this formula [tex]a^2+b^2=c^2[/tex] and since we already know b and c we can plug that in to find out what a could be but we won't actually solve it.
[tex]a^2+b^2=c^2\\a^2+4^2=7^2\\a^2+16=49\\a^2=33\\\sqrt{a^2}=\sqrt{33}\\a=\sqrt{33}[/tex]
So a would equal whatever the square root of 33 is.

Solve 4(5x+2)=14x+32
Answer:
x=4
Step-by-step explanation:
4(5x+2)=14x+32
20x+8 = 14x+32
20x-14x+8=14x-14x +32 (Both side +14x)
6x+8=32 (cancel 14x -14x)
6x+8-8=32 -8(both side -8)
6x=24 (both side divide 6)
6x/6=24/6
x=4
Answer:
34x+34
Step-by-step
20x+2=14x+32
20x+14x=2+32
34x+2+32
2+32=34
34x=34

3x-7=3x-7 - adding the right side together
Solve the following equations
7(3x + 5) - x = 75
Answer:
x = 2
Step-by-step explanation:
7(3x + 5) - x = 75
1. Distributive property
multiply 7 by whatever is in the parenthesis
7*3x + 7*5 - x = 75
21x + 35 - x = 75
2. Combine like terms
21x - x = 20x
20x + 35 = 75
3. Subtract 35 on both sides
20x + 35 - 35 = 75 - 35
20x = 40
4. Divide both sides by 20 since u want to isolate the variable
20x/20 = 40/20
x = 2
And thats ur answer

Step-by-step explanation:
It must be 2:3 so you have to change the current ratio from black to white(7:8) to 2:3
So the first number has to be the closets multiple of 2(8) and you have to divide 8 by 2 to get 4 and multiply that by 3 to get the ratio 8:12 which is equivalent to 2:3

Which inequality is shown in this graph? (0, 2) (-1,-2)
A. y2-4x+ 2
B. yz 4x + 2
C. ys - 4x + 2
D. y = 4x+2
Answer:
D) y = 4x + 2
Step-by-step explanation:
Explanation:-
Given ( 0, 2) ( -1 , -2 )
Given in equalities y = 4x + 2
put point (0,2) in equation y = 4x +2
2 = 4(0) +2
2 = 2
Therefore satisfies the point (0,2) equation y = 4x +2
put point (-1,-2) in equation y = 4x +2
-2 = 4(-1)+2
-2 = -2
Therefore satisfies the point (-1,-2) equation y = 4x +2

The population of a city is 100,000. It doubles each decade for 5 decades. Select all
expressions that represent the population of the city after 5 decades.
A. 32,000
B. 320,000
C. 100,000 -2.2.2.2.2
D. 100,000 - 5 with the power of 2
E. 100,000 - 2 with the power of 5
Answer:
The answer is C and E.
Step-by-step explanation:
I just took the assignment and it is C and E.
The expression that represents the population after 5 decades is
100,000 x [tex]2^5[/tex] or 100,000 x 2 x 2 x 2 x 2 x 2.
Options C and E is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 8 is an equation.
We have,
The population of the city = 100,000
Population doubles every decade.
This means,
Population after 1 decade.
= 100,000 x 2
= 200,000
Population after 2 decades.
= 200,000 x 2 x 2
= 800,000
We can write an expression for the population after x decade.
= 100,000 x [tex]2^x[/tex]
The population after 5 decades.
= 100,000 x [tex]2^5[/tex]
= 100,000 x 2 x 2 x 2 x 2 x 2
= 100,000 x 32
= 3200,000
Thus,
The expression is 100,000 x [tex]2^5[/tex] or 100,000 x 2 x 2 x 2 x 2 x 2.

What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
Sin 30 = 10 / x ______(10
We know that,
Sin 30 = 1/2 _____(2)
