Suppose the doubling time of an investment of $10000 is 12 years. What is the annual
percentage growth rate?
A. 9.5%
B. 4.1%
C. 5.9%
The annual percentage growth rate is 5.9%
The doubling time of an investment of $10000 is 12 years
The compound interest caluclated annually can be given by
A=P(1 + r/n)^nt
where A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period

Answer:
a = 108°
b = 72°
c = 48°
d = 48°
Step-by-step explanation:
• ∠a and the 72° angle are on a straight line. Therefore they add up to 180°:
∠a + 72° = 180°
⇒ ∠a = 180 - 72°
⇒ ∠a = 108°
• ∠b and the 72° angle are corresponding angles (the angles make an F-shape). Therefore, they are equal:
∠b = 72°
• ∠d and the 48° angle are alternate angles (the angles make a z-shape). Therefore they are equal:
∠d = 48°
• ∠c and ∠d are vertically opposite angles. Therefore, they are equal:
∠c = ∠d
⇒ ∠c = 48°

The slope is -5/3
From the question, we have
slope, m = change in y/change in x
= (-6+1)/(8-5)
=-5/3
The slope, m, is a measure of how steep a line is. Sometimes, the gradient of a line is referred to as its slope. A line's y-intercept, ab, denotes the y-coordinate of the location where the line's graph crosses the y-axis.
Slope of a Line :
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate.
Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.
As a result, m = change in y/change in x = y/x is the formula for the change in y-coordinate with respect to the change in x-coordinate.
where "m" represents a line's slope.
The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.

What is the probability that your first strike was a critical hit but not your second strike?
What is the probability that you are able to cause damage?
What is the probability that your strike was not critical but your next 2 attacks were?
The probabilities in this problem are given as follows:
First strike is a critical hit: 33%.First strike is not a critical hit: 67%.First strike is critical and the second is not: 22%.Cause damage: 11%Not critical followed by two criticals: 7%.What are the probabilities?The probabilities for each strike are given as follows:
Critical hit: 33%.Not a critical hit: 67%, as 100 - 33 = 67.The probabilities are independent, meaning that for each trial they are the same.
Thus the probability that your first strike was a critical hit but not your second strike is obtained as follows:
P = 0.33 x 0.67 = 0.2211 = 22%. (rounded).
Damage is caused with two consecutive critical hits, hence:
p = 0.33 x 0.33 = 0.11 = 11%.
The final probability, that your strike was not critical but your next 2 attacks were, is obtained as follows:
p = 0.67 x 0.33 x 0.33 = 0.07 = 7%.

dollars
(b) Interpret it. (Round your answer to one decimal place.)
Over time, you should expect to lose about
cents for every dollar you bet.
Refer to the picture if needed
Considering a discrete distribution modeling the situation, it is found that:
a) The expected value of each $1 bet in roulette is of: -$0.988.
b) The interpretation is given as follows: Over time, you should expect to lose about 999 cents for every dollar you bet.
What is the expected value of a discrete distribution?The expected value of a discrete distribution is calculated as the sum of each outcome multiplied by it's respective probability.
The total number of outcomes for the three-number bet is of:
10 x 10 x 10 = 1000.
As three numbers are taken, and for each number, there are 10 possible outcomes.
Hence the probability of winning is of:
p = 1/1000.
As there is only one correct sequence.
The probability of losing is of:
p = 1 - 1/1000 = 999/1000.
Considering a payout of $11 for a $1 bet, the distribution of earnings is presented as follows:
P(X = 11) = 1/1000.P(X = -1) = 999/1000.Hence the expected value of a $1 bet is calculated as follows:
E(X) = 11/1000 - 999/1000 = -$0.988.
Which means that you are expected to lose approximately 99 cents for every dollar that you bet.

Answer:
t=1.33333 seconds
Step-by-step explanation:
1. We are give the the position function, s(t). We must differentiate s(t) twice in order to find the acceleration function, a(t).
s(t) = t⁶-2t⁵
Taking the power rule to differentiate s(t), we find the velocity function, v(t).
v(t) = d/dt (t⁶-2t⁵)
v(t) = 6t⁵-10t⁴
Differentiate v(t) using the power rule again to find the acceleration function, a(t).
a(t) = d/dt (6t⁵-10t⁴)
a(t) = 30t⁴-40t³
2. To find the other t value where acceleration is equal to zero, we must set a(t) to zero.
a(t) = 30t⁴-40t³ = 0
3. Algebraically solve for t. Factoring out 10t³ from a(t), we have:
10t³(3t-4)=0
Our solutions are t=0 and t=4/3.
The other value of t when acceleration is equal to zero is 4/3, or 1.33333 seconds.

Conveyor belt 1 is fasterStep-by-step explanation:
GivenConveyor belt1: m(x) = 157.1xFind the equation of p(x) using table.
We see it is a proportional relationship, therefore:
p(x) = kx125.6 = 2kk = 125.6/2k = 62.8Conveyor belt2: p(x) = 62.8x
As we see 157.1 > 62.8 which means conveyor 1 belt is faster.
Answer:
The conveyor belt 1 is faster.
Step-by-step explanation:
Speed of conveyor belt 1,
→ m(x) = 157.1x
Now the speed of conveyor belt 2,
→ p(x) = x
→ p(125.6) = 2x || p(188.4) = 3x
→ x = 125.6/2 || x = 188.4/3
→ [ p(x) = 62.8 ] || [ p(x) = 62.8 ]
Then the fastest conveyor is,
→ m(x) = 157.1x > p(x) = 62.8
→ 157.1x > 62.8
→ Conveyor 1 > Conveyor 2
Hence, the conveyor belt 1 is faster.

The first quartile is
86.135 is the IQ score separating the bottom 25% from the top 75%.
The number between a data set's lowest and median is known as the first quartile. We would utilize a Z table to locate it.
As we are looking on the left side of distribution, value of z-score will be negative.
z-score equation for x : [tex]z = \frac{x-M}{S}[/tex]
[tex]x = zS+M[/tex]
where x = value we're looking for
M = Mean
= 99.2
S = Standard deviation
= 19.5
z = z-score
= -0.67
Putting the value in equation,
x = -0.67*19.5 + 99.2
= -13.065 + 99.2

Answer:
B. The graph of K has a greater y-intercept
D. The graph of J has a greater slope.
Step-by-step explanation:
Given a table for function J and an equation for function K, you want to know which has the greater slope, and which has the greater y-intercept.
Y-interceptThe y-intercept is the value of the function when x=0. We see from the table that y=2 corresponds to x=0 for function J.
We see from the equation for function K that the constant is 8. This is the value of y when x=0.
Function K has the greater y-intercept (8 vs. 2).
SlopeThe slope is the change in y-value when x increases by 1 unit. We see from the table that y=7 when x=1, so the change in y from x=0 to x=1 is 7-2 = 5. The slope of function J is 5.
The equation for function K has an x-coefficient of 3. This means a change in x of 1 unit will result in a change in y of 3 units. The slope of function K is 3.
Function J has the greater slope (5 vs. 3).
Additional comment
Both functions are graphed in the attachment. The y-intercepts have their points labeled. The graph with the steeper slope is the blue line, function J.
