You randomly select two poker chips from a bag containing 7 poker chips: 4 red, 1 blue, 1 green, and 1 white. Consider the following events:
Event A: You select a green poker chip
Event B: You select a white poker chip.
Determine whether the following statement is True or False: Events A and B are statistically independent.
Answer:
P[You select a green poker chip] = 1/7
P[You select a white poker chip] = 1/7
Step-by-step explanation:
Given:
Number of chips beg contain = 7 chips
Number of red chips = 4 chips
Number of blue chips = 1 chips
Number of green chips = 1 chips
Number of white chips = 1 chips
Find:
Event A: You select a green poker chip
Event B: You select a white poker chip
Computation:
P[You select a green poker chip] = Number of green chips / Number of chips beg contain
P[You select a green poker chip] = 1/7
P[You select a white poker chip] = Number of white chips / Number of chips beg contain
P[You select a white poker chip] = 1/7

A company manufactures CD drives that have a 1.6% chance of experiencing disc-read errors. If a CD drive is tested for 250 read operations, the number of times it may fail is
Answer:
The answer is 4.
Step-by-step explanation:
Multiply 250 with 1.6%. 1.6% is also written as 0.016.
So pretty much you multiply 250 with 0.016 and you get 4.

Answer:
C
Step-by-step explanation:
Hi there!
We're given a rectangle with one side marked as 16 and another marked as 12
We need to find the length of the diagonal
Rectangles have a property that makes the opposite sides congruent. Therefore, the side opposite to the side marked as 16 is also 16 and the side opposite to the side marked as 12 is also 12 because of that property.
Now let's look at the shapes cut by the diagonal; they are right triangles.
We only need to look at one of the triangles for this problem
The measures of 12 and 16 in the triangle are the legs (sides that make up the right angle) and the diagonal is the hypotenuse (the side that is opposite to the right angle).
You can absolutely solve for the diagonal/hypotenuse by doing Pythagorean theorem, but there's a shortcut:
3, 4, 5 is a common Pythagorean triple
(3²+4²=5²)
(9+16=25)
(25=25)
You may notice that dividing 12 and 16 by 4 are equal to 3 and 4 respectively
that means it's a 3, 4, 5 triangle, just by multiplied 4
So that means the hypotenuse has to be 5 * 4, which is equal to 20 inches
Therefore the answer is C
Hope this helps!

The figure shown is created by joining three rectangles. Enter the area of the figure, in square centimeters. Round to the nearest hundredth.
Answer:
46.75 cm²
Step-by-step explanation:
The figure can be decomposed into 3 rectangles.
Area of the figure = area of rectangle A + area of rectangle B + area of rectangle C
✔️Area of rectangle A = L*W
L = 4 cm
W = 5½ cm = 5.5 cm
Area = 4*5.5 = 22 cm²
✔️Area of rectangle B = L*W
L = 8½ - (4 + 3) = 8½ - 7 = 1.5 cm
W = 5½ - 2 = 3.5 cm
Area = 1.5*3.5 = 5.25 cm²
✔️Area of rectangle C = L*W
L = 3 cm
W = 6½ cm = 6.5 cm
Area = 3*6.5 = 19.5 cm²
✔️Area of the figure = 22 + 5.25 + 19.5 = 46.75 cm²

To celebrate 24 years in business, a clothing store's marketing executive is ordering scratch-off discount coupons to give to customers. She would like 40% of customers in the population to receive the highest possible discount, with an SEP of 0.01 for this population. How many coupons should she order?
Answer:
She should order 2400 coupons.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
She would like 40% of customers in the population to receive the highest possible discount, with an SEP of 0.01 for this population.
This means that [tex]p = 0.4, s = 0.01[/tex]
How many coupons should she order?
We have to find n. So
[tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
[tex]0.01 = \sqrt{\frac{0.4*0.6}{n}}[/tex]
[tex]0.01\sqrt{n} = \sqrt{0.4*0.6}[/tex]
[tex]\sqrt{n} = \frac{\sqrt{0.4*0.6}}{0.01}[/tex]
[tex](\sqrt{n})^2 = (\frac{\sqrt{0.4*0.6}}{0.01})^2[/tex]
[tex]n = 2400[/tex]
She should order 2400 coupons.
A triangular prism has a base length of 1.5 centimeters, a base height of 3 centimeters, and a height of 12 centimeters.
Question 1
Part A
Find the volume of the prism.
Enter the correct answer in the box.
Answer:
V=[tex]27 cm^{3} \\[/tex]
Step-by-step explanation:
[tex]Area -of-triangle=\frac{1}{2} \times base\times height=0.5\times1.5\times 3=2.25cm^{2} \\Vol=Area\times height= 2.25\times 12=27 cm^{3} \\[/tex]
Answer:
Part A: 108
Part B: 24.
Step-by-step explanation:
Explanation: The formula for volume of a prism is V=Bh. (B is base area and H is height). The information doesn't provide base area so you need to find base area. The formula for base area is 1/2 x base side x height, so 1/2 x 1.5 x 12 = 9. (This is the formula for triangular prism.) Now do the volume formula; 9 x 12 = 108. Now for part B: Divide the volume by the base area. 108 / 4 1/2 = 24. So the answer for A is 108 and for B it's 24. Check your answer: 4 1/2 x 24 = 108.

The x-coordinate will be cosθ and the y-coordinate will be sinθ.
What are polar coordinates?Polar coordinates are a two-dimensional coordinate system in which each point on a plane is determined by a distance from a fixed point called the pole and an angle from a fixed direction called the polar axis.
The distance from the pole is called the radial coordinate or radius, denoted by "r", and the angle is called the angular coordinate or polar angle, denoted by "θ".
Polar coordinates are often used in situations where the Cartesian coordinates (x, y) are not convenient, such as in polar graphs, 3D coordinate systems, and certain physics and engineering applications.
For the point P, the coordinates will be,
x-coordinate: cosθ
y-coordinate: sinθ

now use 'y=mx+b' to find the y-intercept (the 'b'):
2 = 0(5) + b
2 = b

Keenan is playing darts. So far, he has hit the bullseye 2 times and missed the bullseye 8 times. Considering this data, how many bullseyes would you expect Keenan to get during his next 20 tosses?
Answer:
4 times
Step-by-step explanation:
First you take the number of times and divide them by the number of times he attempted it. (2)/(8+2) or 1/5. Then you set up an inequality which would look like this. x/20=1/5 then you will cross multiply them to get this equation 5x=20. then you solve for x and you would get x=4. So you can expect him to hit four bullseyes in the next 20 attempts.

An airplane ticket has an area of 119 square centimeters. Its perimeter is 48 centimeters. What are the dimensions of the ticket?
Answer:
17cm ×7cm
Step-by-step explanation:
Assuming that the airplane ticket is a rectangle,
let the length and the breadth of the ticket be L cm and B cm respectively.
LB= 119 -----(1)
2(L +B)= 48
L +B= 48 ÷2
L +B= 24 -----(2)
From (2):
L= 24 -B -----(3)
Substitute (3) into (1):
B(24 -B)= 119
24B -B²= 119 (expand)
B² -24B +119= 0
(B -17)(B -7)= 0 (factorise)
B -17= 0 or B -7= 0
B= 17 or B= 7
Substitute the values of B into (3):
L= 24 -17 or L= 24 -7
L= 7 or L= 17
∴ The dimensions of the airplane ticket is 17cm ×7cm.
a Cylindial water tank carries a volume of 150 lwhen it's tell full.The water tank has a base surface with a diameter of 140 cm. what is the height of the water tank.
Answer:
9.744180189 cm
Step-by-step explanation:
1 liter = 1 dm³ (cube with 10cm side lengths) =
= 10×10×10 cm³ = 1000 cm³
the volume of a cylinder is
base area × height
and the base area is a circle
area = pi×r²
r (radius) is half the diameter.
so, we know
volume = 150000 cm³
r = diameter/2 = 70 cm
so, we have
150000 = pi×r² × height = pi×70² × height =
= pi×4900 × height
1500 = pi×49 × height
height = 1500 / (pi×49) = 9.744180189... cm
