percentage back the next day. How much money is the stock valued at the end of the second day?
Answer: 2192.08
Step-by-step explanation:
6/100=0.06
1 - 0.06= 0.94
1 + 0.06= 1.06
2200*094*1.06= 2192.08
The value of the stock at the end of the second day is $2192.08.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
Value of stock = $2200
At the end of the first day →
6% decrement
6$ of 2200 ⇒ 2200 × 6/100 = 132
So,
2200 - 132 = $2068
At the end of the second day →
6% increment
6$ of 2068⇒ 2068× 6/100 = 124.08
So,
2068 + 124.08= $$2192.08
Hence "The value of the stock at the end of the second day is $2192.08".

Consider the following random experiment. First, roll a die and observe the number of dots facing up; then, toss a coin the number of times that the die shows and observe the total number of heads. For example, if the die shows three dots facing up and the coin (which is then tossed three times) comes up heads exactly twice, then the outcome of the experiment can be represented as (3, 2).
a. Determine a sample space for this experiment.
b. Determine the event that the total number of heads is even.
Answer:
{(1, 0), (1, 1), (2,0), (2,1), (2, 2), (3,0), (3,1), (3,2), (3,3), (4, 0), (4,1), (4,2), (4,3), (4,4), (5,0), (5,1),(5,2), (5,3), (5,4), (5,5), (6,0), (6,1),(6,2), (6,3), (6,4), (6,5), (6,6)}
B.)
{(2,2), (3,2), (4,2), (4,4), (5,2), (5,4), (6,2), (6,4), (6,6)}
Step-by-step explanation:
Sample space :
Die roll, then number of coin tosses based on the outcome of the die roll, then number of heada from the toss(es) is recorded along with the outcome of the die roll.
{(1, 0), (1, 1), (2,0), (2,1), (2, 2), (3,0), (3,1), (3,2), (3,3), (4, 0), (4,1), (4,2), (4,3), (4,4), (5,0), (5,1),(5,2), (5,3), (5,4), (5,5), (6,0), (6,1),(6,2), (6,3), (6,4), (6,5), (6,6)}
Event that the total number of head is even:
{(2,2), (3,2), (4,2), (4,4), (5,2), (5,4), (6,2), (6,4), (6,6)}
g Scores of an IQ test have a bell-shaped distribution with a mean of 100 and a standard deviation of 12. Use the empirical rule to determine the following. (a) What percentage of people has an IQ score between 76 and 124? (b) What percentage of people has an IQ score less than 64 or greater than 136? (c) What percentage of people has an IQ score greater than 136?
Answer:
a) 95% of people has an IQ score between 76 and 124.
b) 0.3% of people has an IQ score less than 64 or greater than 136.
c) 0.15% of people has an IQ score greater than 136
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 100
Standard deviation = 12
(a) What percentage of people has an IQ score between 76 and 124?
76 = 100 - 2*12
124 = 100 + 2*12
So within 2 standard deviations of the mean, and the percentage is 95%.
(b) What percentage of people has an IQ score less than 64 or greater than 136?
64 = 100 - 3*12
136 = 100 + 3*12
99.7% of people has scores between 64 and 136. So 100 - 99.7 = 0.3% of people has an IQ score less than 64 or greater than 136.
(c) What percentage of people has an IQ score greater than 136?
0.3% of people has an IQ score less than 64 or greater than 136.
Since the normal distribution is symmetric, 0.3%/2 = 0.15% are below 64 are 0.15% are above 136.

Lines R and S are parallel. Find the value of x, then find the measure of 21 and 22.
m21=(74 - x)º
m22 =(85 – 2x)
Answer:
a) The value of x = 11°
b) m21 = 63°
m22= 63°
Step-by-step explanation:
Step(i):-
Given that the lines R and S are parallel
Given that M21 = (74-x)°
M22 = (85-2x)°
Equating angles
(74-x)° = (85-2x)°
74 - 85 = x -2x
-11 = -x
x = 11°
Step(ii):-
Put x = 11°
⇒ m21 = ( 74 -11) ° = 63°
⇒ m22 = (85-2(11))° = (85-22)° = 63°
Final answer:-
a) The value of x = 11°
b) m21 = 63°
m22= 63°

Answer:
a) not proportional
b) proportional; k = [tex]-\frac{3}{5}[/tex]
Step-by-step explanation:
a) for any proportional equation, the line must pass through the origin. The equation in a) is y = 4x + 1, and the '+1' is the y-intercept. This means that the line does not pass through the origin, so x and y cannot increase by the same amount (i.e. they are not proportional).
Another way to determine this is is to use the y = kx base. If you have an equation that fits that it's likely proportional.
Here, if the equation was only y = 4x then it'd be proportional because u can see that k = 4. This is not the equation though, and the 4x + 1 doesn't fit to the y = kx formula so it can't be proportional.
b) straight away you can see that there's no 'c' term (y = mx + c) which means the y-intercept is 0, so the line passes through the origin. While this does not immediately mean the line is proportional, you can make sure that it is by checking it fits with the y = kx equation.
y = -(3/5)x fits with y = kx, with k being -3/5

What is the probability of spinning a number greater than 5 on a spinner numbered 1-8 and tossing a tail on a coin
Answer:
3/16
Step-by-step explanation:
P(6,7,8 and 'T') = 3/8 x 1/2 = 3/16
Answer:
12/64
Step-by-step explanation:
We have numbers 1-8 = /8
We have the numbers 6, 7, 8 on the spinner = 3/8
We have the event it doesn't get over 8 too = 8/8-3/8 = 5/8
To use if the question has two events for spinner.
We toss a coin = H or T = 1/2
We convert a 3/8 and 1/2 to same HCF = 4/8 = ( 2x 4 = 8)
3/8 x 4/8 = 12/64

The length of a rectangle is (3 + √7)m and its width is (1 + 2√7)n. What is the
area of the rectangle?
Answer:
[tex]A=(17+7\sqrt7)\ m^2[/tex]
Step-by-step explanation:
Given that,
The length of the rectangle, [tex]l=(3+\sqrt7)\ m[/tex]
The width of the rectangle, [tex]b=(1+2\sqrt{7} )\ m[/tex]
We need to find the area of the rectangle. We know that the area of the rectangle is given by :
[tex]A=l\times b[/tex]
Put all the values in the above formula.
[tex]A=(3+\sqrt7)\times (1+2\sqrt7)\\\\=3+3\times 2\sqrt7 +\sqrt7+2(\sqrt7)^2\\\\=3+6\sqrt7+\sqrt7+14\\\\=(17+7\sqrt7)\ m^2[/tex]
So, the area of the rectangle is [tex](17+7\sqrt7)\ m^2[/tex].

The sequence could be of all even numbers, so 2, 4, 6, 8, etc.
Or of all powers of 2, starting at 2, so 2, 4, 8, 16, etc.
Since there are an infinite number of sequences that fit the pattern, you just have to choose the most likely.

How many baseballs will fit in a cylindrical barrel
that has a diameter of 4 ft and a height of 6 ft?
Answer:
5935 base balls
Step-by-step explanation:
Volume of a cylinder : pi * r² * h
r = Radius, h = height = 6ft
Diameter = 4ft ; Radius = diameter / 2 = 4/2 = 2ft
V = π * 2^2 * 6
V = 75.398223 ft³
Diameter of baseball = 2.8 inches
2.8 inches = 2.8 × 2.8 * 2.8 = 21.952 in³ = 0.0127037 ft³
Hence,
75.398223 ft³ / 0.0127037ft³
= 5935.1370
= 5935 base balls

Find x. Round to the nearest tenth.
By knowing all sides of triangle and applying the formula of the law of the cosines we conclude that the missing angle X is approximately 117.9°.
How to find the missing angle
In this question we have a triangle with three known side lengths but all missing angles, we can determine the missing angle by using the law of cosines. If we know that x = 90 ft, y = 55 ft and and z = 50 ft, then the missing angle X is:
90² = 55² + 50² - 2 · 55 · 50 · cos X (1)
