The total amount in the acount in 5 years is approximately $13,321.76.
What is the accrued amount in the account in 5 years?The formula accrued amount in a compounded interest is expressed as;
[tex]A = P( 1 + \frac{r}{n} )^{n*t}[/tex]
Where A is accrued amount, P is principal, r is interest rate and t is time.
Given that:
Principal P = $10,000Compounded monthly n = 12Time t = 5 yearsInterest rate r = 5 3/4% = 5.75%Accrued amount A = ?First, convert R as a percent to r as a decimal
r = R/100
r = 5.75/100
r = 0.0575
Plug the given values into the above formula and solve for A.
[tex]A = P( 1 + \frac{r}{n} )^{n*t}\\\\A = 10000( 1 + \frac{0.0575}{12} )^{(12*5)}\\[/tex]

P(RI-T) = 0.25, P(-R|T) = 0.2, P(T) = 0.1
What is P(R)?
O 0.245
O insufficient information
O 0.1060
O 0.305
Answer:
We can use Bayes' theorem to calculate P(R), which states that the probability of an event A given event B is equal to the probability of B given A multiplied by the probability of A, divided by the probability of B:
P(R|T) = P(T|R) * P(R) / P(T)
We can rearrange this equation to solve for P(R):
P(R) = P(R|T) * P(T) / P(T|R)
We are given that P(RI-T) = 0.25, which can be written as:
P(R∩T) = P(R|T) * P(T) = 0.25
We are also given that P(-R|T) = 0.2, which can be written as:
P(-R∩T) = P(-R|T) * P(T) = 0.2 * 0.1 = 0.02
We can use the law of total probability to find P(T|R):
P(T|R) = P(RI-T) / P(R) = 0.25 / P(R)
We can substitute these values into the equation for P(R) to get:
P(R) = P(R|T) * P(T) / P(T|R)
= 0.25 / [P(T|R) * P(T) + P(-R|T) * P(T)]
= 0.25 / [0.25 + 0.02]
= 0.1060
Therefore, the answer is option C: 0.1060.

Answer: 29
Step-by-step explanation:
<F is 29 degrees because 180-58=122 and 180-122= 58, so then you divide 58 by 2 to get 29 for each x. The x's are each equal to 29.
Answer:
29 degrees
Step-by-step explanation:
The problem shows angle HGE as 58 degrees.
Segment HF is 180 degrees so we can subtract 58 from 180 to get 122 degrees for angle g
Now, the sum of all angles in a triangle is 180.
So, there are 3 angles in the triangle:
g(we know this is 122)
e
f
the graph denotes that the measures of angle e and f are the same because they are the same variable.
Lets subtract 122 from 180 to get 58.
So, angle e and f together combine to make 58 degrees.
But we also know that e and f have the same measure.
So, to find the measure of f, simply divide 58/2 to get 29 degrees.

How to determine an equation of this line?In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical expression:
y - y₁ = m(x - x₁)
Where:
x and y represent the data points.m represent the slope.First of all, we would determine the slope of this line;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (0 - 360)/(30 - 0)
Slope (m) = -360/30
Slope (m) = -12
At data point (0, 360) and a slope of -12, a linear equation for this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y - 360 = -12(x - 0)
y = -12x + 360
A = 360 - 12x
For Sally, the time to finish;
360 = 12x
x = 360/12 = 30 min.
For Lisa, the time to finish;
392 = 14x
x = 392/14 = 28 min (Lisa will finish painting before Sally)
For Sally, when x = 10;
A = 360 - 12(10)
A = 240 sq. feet.
For Lisa, when x = 10;
A = 392 - 14(10)
A = 252 sq. feet.
For Sally, when x = 20;
A = 360 - 12(20)
A = 120 sq. feet.
For Lisa, when x = 20;
A = 392 - 14(20)
A = 112 sq. feet.

Find the LCD of the given rational equation
The LCD of the rational equation above is 4(x + 7)(x - 7).
What is the explanation for the above response?To find the LCD (Least Common Denominator) of the given rational equation, we need to factor the denominators of each fraction and then take the product of the highest powers of each factor.
The first denominator, x^2 - 49, can be factored using the difference of squares formula:
x^2 - 49 = (x + 7)(x - 7)
The second denominator, 4x + 28, can be factored by factoring out the greatest common factor:
4x + 28 = 4(x + 7)
Therefore, the LCD is the product of the highest powers of each factor, which is:
LCD = 4(x + 7)(x - 7)
So we need to multiply each term in the equation by an appropriate form of 1 so that the denominators of all the fractions become the LCD, 4(x + 7)(x - 7).

a. Construct and interpret a 95% confidence interval for the proportion of all
teenagers in the United States who would respond that they use a video
streaming service every day.
b. Based on the confidence interval in part (a), do the sample data provide
convincing statistical evidence that the proportion of all teenagers in the United
States who would respond that they use a video streaming service every day is
not 0.5? Justify your answer.
Mean Standard Deviation Sample Size
Standard care 0.57 0.26 56
New treatment 0.69 0.27 56
2. Patients experiencing symptoms of a heart attack are routinely transported to a
hospital in an ambulance. In a study of a new treatment thought to reduce damage to
the heart, patients experiencing symptoms of a heart attack were randomly assigned to
one of two groups. During transportation to the hospital, patients in one group received
standard care, and patients in the other group received the new treatment consisting of
standard care and the application of a blood pressure cuff.
The response variable measured for each patient was a number between 0 and 1,
referred to as the myocardial salvage index (MSI). A higher MSI value indicates a more
positive outcome for the patient. Summary statistics for the MSI responses of the two
groups are shown in the table.
Do the data provide convincing statistical evidence that the new treatment results in a
higher mean MSI value than does the standard care among people similar to the
patients in the study?
Since the calculated t-value is greater than the critical t-value, we reject the null hypothesis, concluding that there's convincing evidence that the new treatment results in a higher mean MSI value than standard care.
How to solvea. The 95% confidence interval for the proportion of teenagers using video streaming services daily is (0.5579, 0.6221). This means we're 95% confident that 55.79% to 62.21% of US teenagers use such services daily.
b. The results demonstrate that the proportion is not 0.5 because the full confidence interval is higher than 0.5.2. We obtain a t-value of roughly 2.51 with 108.52 degrees of freedom using a two-sample t-test.
At a significance level of 0.05, the critical t-value for a one-tailed test is approximately 1.66.
Since the calculated t-value is greater than the critical t-value, we reject the null hypothesis, concluding that there's convincing evidence that the new treatment results in a higher mean MSI value than standard care.

14. The distance between (x, 2) and (0, 6) is 5 units. Use the Distance Formula to determine
the value of x. Show all your work.
Answer:
The value of x is 3.
Step-by-step explanation:
The Distance Formula is:
d = √[(x2 - x1)² + (y2 - y1)²]
Using the given points, we have:
d = √[(0 - x)² + (6 - 2)²]
Simplifying inside the square root gives:
d = √[x² + 16]
We know that the distance between (x, 2) and (0, 6) is 5 units, so we can set up the equation:
5 = √[x² + 16]
Squaring both sides gives:
25 = x² + 16
Subtracting 16 from both sides gives:
9 = x²
Taking the square root of both sides gives:
x = ±3
Since we are looking for the value of x, we choose the positive solution:
x = 3
Therefore, the value of x is 3.

is 2^7 equal to 2x 7
Answer: No, 2^7 is not equal to 2x7.
2^7 means 2 raised to the power of 7, which is 2 multiplied by itself 7 times:
2^7 = 2 x 2 x 2 x 2 x 2 x 2 x 2 = 128
On the other hand, 2x7 means 2 multiplied by 7:
2x7 = 2 x 7 = 14
So 2^7 is not equal to 2x7.
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
See, 2 ^ 7 is 2 TO THE POWER OF 7, which is repeated multiplication.
2 x 7 is 2 MULTIPLIED BY 7
2 ^ 7 written out completely is:
2 * 2 * 2 * 2 * 2 * 2 * 2 = 128
See the repeated multiplication above?
2 x 7 is just 14.
See the difference!
14 is NOT equal to 128

On Monday Harriet ate 1/4 of a 8 slice of pizza on Tuesday she ate 1/2 of the same pizza what fraction of The Whole Pizza did she eat
Harriet ate a total of 3/4 of the total pizza
Given data ,
On Monday Harriet ate 1/4 of a 8 slice of pizza
And , on Tuesday she ate 1/2 of the same pizza
Now , If the pizza has 8 slices, then Harriet ate 1/4 of 8 slices on Monday, which is 2 slices.
On Tuesday, Harriet ate 1/2 of the same pizza, which is 4 slices.
So, in total, Harriet ate 2 + 4 = 6 slices of pizza
On simplifying the equation , we get
The whole pizza has 8 slices, so Harriet ate 6/8 of the pizza, which simplifies to 3/4.
Hence , Harriet ate 3/4 of the whole pizza

The length of ON for the intersecting secants is derived to be equal to 14
What is the intersecting secant theoremThe intersecting secant theorem, also known as the secant-secant theorem, states that when two secant lines intersect outside a circle, the product of the length of one secant segment and its external segment is equal to the product of the length of the other secant segment and its external segment.
MK × KL = MO × MN
note that KL = (ON - 3) so;
[13 + (ON - 3)] × 13 = (12 + ON) × 12
13(10 + ON) = 144 + 12ON
130 + 13ON = 144 + 12ON
13ON - 12ON = 144 - 130 {collect like terms}
ON = 14
Therefore, the length of ON for the intersecting secants is derived to be equal to 14

A pair of standard dice are rolled. Find the
probability of rolling a sum of 7 with these dice.
Answer:
6 out of 36 or 1 out of 6
Step-by-step explanation:
There are 36 possible ways two dice can roll, so the probability of the sum of seven is 6 out of 36, or 1/6.
[tex]\boxed{\sf 16.67\%}.[/tex]
Step-by-step explanation:1. Determine the total amount of different outcomes.So since we have a pair of dice, assuming they are standard 6 faced dices, the total amount of outcomes is given by just multiplying the number of faces or different numbers that the dices can present:
6 x 6 = 36 possible outcomes.
2. Determine the amout of outcomes that meet the requirement of adding up to 7.Now, here we need to count all the possible cases where the outcome of both dices will equal 7. And there are said cases:
1 + 6 = 7
Explanation. Here the first dice presented number 1 and the second presented number 6, adding up to 7.
Other cases that meet the requirement:
2 + 5 = 7
3 + 4 = 7
4 + 3 = 7
5 + 2 = 7
6 + 1 = 7
So the total amount of events that will meet the requirement is 6.
3. Find the probability.So if we have an event with 36 possible outcomes, and only 6 of those 36 outcomes will mean a success on the experiment. Then, to find the probability of those 6 events from happening all we need to do is divide the amount of events considered "success" which is the numbers adding up to 7 by the total amout of outcomes (36).
So, the probability of rolling a sum of 7 with 2 dices is:
[tex]\sf P(\dfrac{6}{36} )=\dfrac{1}{6} =\boxed{\sf 16.67\%}.[/tex]
