Approximate value of P(|X| > a) is attached below
Ф ( 0 ) is the CDF of standard Normal variate
Step-by-step explanation:
x ~ Bin ( n, p )
E ( x ) = np , Var ( x ) = np ( 1 - p )
∴ Z = Iin ( x - E(x) ) / √Var x ) ~ N ( 0, 1 ) ( this is the standard normal Variate)
n-1∞
Find the approximate value of P(|X| > a)
Ф ( 0 ) is the CDF of standard Normal variate
attached below is the remaining part of the solution
Find the measure of n in the following figure.
OK / OL = KN / LM
5 / 10 = n / 8
1 / 2 = n / 8
n = 4
Two lines intersect creating angles with the measures shown below.
(2x + 6)°
32°
What is the value of x?
Answer:
The angles are called Vertical Angles. And vertical angles are always equal. So,
2x + 6 = 32
2x = 26
x = 13
Lisa selects a marble from a jar containing 6 red marbles and 2 green marbles and does not replace it. She then selects a second marble. What is the probability that both marbles will be red?
Answer:
15/28 = 53.57%
Step-by-step explanation:
E 1 = select a red marble
E2 = select a red marble
E 1 ∩ E2
6/8 x 5/7
3/4 x 5/7 = 15/28 = 53,57%

Answer:
c. 3680
Step-by-step explanation:
In 2010, the population was 8000.
In 2014, it increased by 15%.
Population in 2014 :
= 8000 + 15/100×8000
= 8000 + 1200
= 9200.
Now, 2/5 of the population was age 12 or under.
= 2/5 × 9200
= 2×1840
= 3680
Answer - c) 3680
The ratio of Luis´s salary and Andres´s salary is 5 to 3. In July by mistake, Andres received $720 more, which received the same amount from Luis. How much is Luis´s salary?
Answer:
Luis Salary is 1800 dollars
Step-by-step explanation:
Ration of Luis´s salary and Andres´s salary is 5:3
[tex]\frac{L}{A} = \frac{5}{3}\\3L -5A = 0[/tex] -- Eq (1)
Let Luis salary be X
Then Andrews salary in July would be A + 720 while Luis salary in July is L
L = A + 720 ---E q (2)
Substituting the values in above equation 1, we get -
[tex]3 ( A +720 ) -5A = 0\\2 A = 720 *3\\A = 1080[/tex]
Luis Salary is
[tex]A + 720 = 1800[/tex]

Your school is planning a field trip to the zoo. There are two different bus companies that the school can use. Bus company A has a $40 rental fee plus $6 for each student. Bus company B has a $120 rental fee plus $2 for each student. How many students will need to go in order for the bus to cost the same from both companies?
Answer:
ok can you storten it.hyyyyuu7766ttt5rrrrrttttttttttyy
Answer:
20 students for $160
Step-by-step explanation:
bus a: y = 6x + 40
bus b: = 2x + 140
x = # of students | y = cost
FOR X: *set equations = to each other*
6x + 40 = 2x + 140 *subtract 2x from both sides*
4x + 40 = 120 *subtract 40 from both sides*
4x = 80 *divide by 4 on both sides*
x = 20
FOR Y:
y = 6x + 40 *plug in 20 for x and solve*
y = 6 (20) + 40
y = 120 + 40
y = 160
hese are the values in Paul’s data set.
(1,21),(2,16),(4,10),(5,5),(6,2)
Paul determined the equation of a linear regression line, and determined that these are the predicted values.
(1,20),(2,17),(4,9),(5,6),(6,2)
Use the point tool to graph the residual plot for the data set.
Answer:
Use the plot
20 - 21 = -1 (1, -1)
17 - 16 = 1 (2, 1)
9 - 10 = -1 (4, -1)
6 - 5 = 1 (5, 1)
2 - 2 = 0 (6, 0)

The Toblerone company packages chocolate candy in a container that is a triangular prism. The base is an
equilateral triangle and each side of the triangle is 60 mm. The height of the triangular prism is 405 mm.
1) What is the total surface area of this triangular prism? Show all work and give answers to 2 decimal
places
2) What is the volume of this triangular prism? Show all work and give answers to 2 decimal places
3) If the chocolate inside the package is 335954.96 mm3,how much empty volume/space is inside the
container? Show all work and give answers to 2 decimal places
Answer:
76017.69 mm²
631000 mm³
295045.04 mm³
Step-by-step explanation:
Surface area = bh + 2ls + lb
Since the sides of the triangular prism are equal (equilateral triangle) = 60 mm each
Height = 405 mm
The surface area of triangular = 76017.69 mm
The volume of triangular prism :
1/2 * base * height * length
Volume = 631000 mm³
If amount of chocolate inside = 335954.96 mm3
Empty space =
Volume of triangular prism - amount of chocolate inside
631000 - 335954.96
= 295045.04 mm³
