Find the normal approximation to the chance that the face with six spots appears between 9, 10, or 11 times.
The exact chance that the face with six spots appears 9, 10, or 11 times?
my solution; in one roll of the die P(6 spots)=16 In 60 rolls of the die the expected number of times the face with 6 spots appears is given by E(X)=Mean=606=10 times.
SE(6spots)=SD=SQR(606⋅56)=2.8868
Applying the normal approximation to the chance that the face with six spots appears 10 times, I obtain the following: mean = 10
Standard deviation=2.8868
Using the continuity correction of 0.5 the following z-scores are found: z1=(9.5−10)/2.8868=−0.1732 and z2=(10.5−10)/2.8868=0.1732 Subtracting the cumulative probabilities for the two z-scores gives 0.5688−0.4312=0.1376 which is the approximate chance that the face with six spots appears 10 times. find the six spots appears between 9,10, or 11?
The exact chance that the face with six spots appears 10 times is found from
60C10(16)10×(56)50=0.137 find six spots appears 9, 10 or 11 times

SYSTEMS OF EQUATIONS)
Answer:
Part A
The required inequality is;
y = 50 - 2 × x ≥ 20
Please find attached the graph of the inequality created with Microsoft Excel
Part B
The number of weeks she can withdraw is less than or equal to 15 weeks
Step-by-step explanation:
The given parameters are;
The amount Kate has in her savings account at the beginning of the summer = $50
The least amount she wants to have in the account at the end of the summer = $20
The amount she withdraws each weak from the account = $2
Part A
Let 'x' represent the number of weeks she can withdraw money, we have;
The required inequality that gives the number of weeks she can withdraw money is given as follows
y = 50 - 2 × x
y ≥ 20
Therefore, the inequality is;
y = 50 - 2 × x ≥ 20
The graph of the inequality created with Microsoft Excel is attached
Part B
The number of 'x' weeks she can withdraw is;
50 - 2 × x ≥ 20
- 2 × x ≥ 20 - 50 = -30
x ≤ -30/(-2) = 15
The number of weeks she can withdraw is x ≤ 15 weeks.

Answer:
x = 6[tex]\sqrt{2}[/tex] = 8.485
Step-by-step explanation:
In a 45-45-90 triangle, the hypotenuse is [tex]\sqrt{2}[/tex] times the length of a leg.
So, if you are given the hypotenuse, then divide its length by [tex]\sqrt{2}[/tex]
x = 12/[tex]\sqrt{2}[/tex] = 12[tex]\sqrt{2}[/tex]/2 = 6[tex]\sqrt{2}[/tex] = 8.485

Choose all answers that apply: Choice A Quadrant I (Choice B) Quadrant II (Choice C) Quadrant III (Choice D) Quadrant IV (Choice E) x-axis (Choice F) y-axis
Answer:
Quadrant III ( C )
Quadrant IV ( D )

Answer:
log Subscript 3 Baseline StartFraction z squared Over 4 EndFraction
Step-by-step explanation:
The single logarithmic form f the expression is [tex]log_3(\frac{9(64z^2)}{81} )[/tex]
Logarithm and indicesGiven the logarithmic expression;
[tex]2(log_38+log_3z)-log_3(3^4-7^2)[/tex]
We are to write it as a single logarithm
Using the product and quotient law of logarithm;
[tex]2(log_38+log_3z)-log_3(3^4-7^2)\\=2(log_38+log_3z)-log_3(\frac{81}{49} )\\=2(log_38z)-log(\frac{81}{9})\\=log_364z^2-log(\frac{81}{9})[/tex]
Simplify the final result to have:
[tex]=log_364z^2-log(\frac{81}{9})\\=log_3(\frac{9(64z^2)}{81} )[/tex]
Hence the single logarithmic form f the expression is [tex]log_3(\frac{9(64z^2)}{81} )[/tex]

When an item is marked down 10% , why does it make sense to multiply the price by 0.9?

For the right triangles below, find the values of the side lengths d and a.
Round your answers to the nearest tenth.
Answer:
a = 1.4 and d = 6.9
Step-by-step explanation:
To get the value of d and a, we will use the SOH CAH TOA identity
For the first tringle;
Opposite = d ((opposite angle 60 degrees)
Adjacent = 4
Tan theta = opp/adj
Tan 60 = d/4
d = 4tan60
d = 4(1.732)
d = 6.9
For the second triangle;
Opposite = a
Hypotenuse = 2
Since sin theta = opp/hyp
Sin45 = a/2
a = 2sin45
a = 2(0.7071)
a = 1.4
Hence a = 1.4 and d = 6.9
If the surface areas of two spheres are in ratio 16:9, then their volumes will be in the ratio
Answer:
64 : 27
Step-by-step explanation:
If linear ratio is a : b , then
area ratio = a² : b²
volume ratio = a³ : b³
Given area ratio = 16 : 9 , then
linear ratio = [tex]\sqrt{16}[/tex] : [tex]\sqrt{9}[/tex] = 4 : 3
volume ratio = 4³ : 3³ = 64 : 27
In problem 8-94 you found that if you are given three lengths to build the sides of a triangle, then if a triangle can be formed, all the triangles you could make were the same. Suppose you start with two triangles knowing that their three pairs of corresponding sides are the same, as shown in the diagram below.
Triangle, A B C, where side, A C, has one hatch mark, side, C B, has 2 hatch marks, and side, A B, has 3 hatch marks.
Triangle, P Q R, where side, R P, has one hatch mark, side, P Q, has 2 hatch marks, and side, R Q, has 3 hatch marks.
Examine the diagram. What do you think the markings indicate? Name the pairs of corresponding sides.
What can you say about the two triangles and why? What can you say about their angles? Why?

Using Euler's formula, the 6th root is easily found.
(64i)^(1/6) = ((2^6)e^(iπ/2))^(1/6) = 2e^(iπ/12) = 2∠15°

Find the linear equation whose graph is the straight line with the given properties through ( 1,-8) and (-1,-1)
The equation of a line for the given coordinates is 7x+2y+9=0.
The given coordinates are (1, -8) and (-1, -1).
We need to find the linear equation whose graph is a straight line.
What is the slope of a line?The slope of a line is defined as the change in the y coordinate with respect to the change in the x coordinate of that line. The slope of a line=m=(y2-y1)/(x2-x1).
Now, slope of the line=(-1-(-8))/(-1-2)
=7/(-2)
=-7/2
Now, put m=-7/2 and (-1, -1) in the equation y=mx+c.
So, -1=(-7/2)(-1)+c
⇒-1-7/2=c
⇒c=-9/2
Then the equation of the line=y=-7x/2-9/2
⇒2y=-7x-9
⇒7x+2y+9=0
Therefore, the equation of a line for the given coordinates is 7x+2y+9=0.
