Question 3:

O (9 x 80) + (9 x 1) 729

Step-by-step explanation:

Distributive Property is used in algebraic expressions, to divide the equation, to make it easier to solve. For question 1,  since it was 20, you must subtract 8 from that answer, because 20 is 1 more than 19. For question 2, (2 x 9) + (2 x 3) would be the same thing as 2(9+3).

The difference in the interest earned on each amount after 4 years is  $1.43. Then, option a is the correct option.

Compound interest is when one receives interest on both interest income and savings.

Consider that you have $1,000 in a savings account earning 5% interest annually. If you earned $50 in the first year, your new balance would be $1,050.

This compound interest can be calculated by,

\(A=P\left(1+\frac{r}{n}\right)^{nt}\)

Where,

For the first half, P is $5,000, r is 3.9%, n is 365 (daily), and t is 4 years.

Then, compound interest for this case is,

\(\begin{aligned}A&=\$5000\left(1+\frac{0.039}{365}\right)^{4\times365}\\&=\$5,844.09\end{aligned}\)

For the second half, P is $5,000, r is 3.9%, n is 12 (monthly), and t is 4 years.

Then, compound interest for this case is,

\(\begin{aligned}A&=\$5000\left(1+\frac{0.039}{12}\right)^{4\times12}\\&=\$5,842.65\end{aligned}\)

Then, the difference is $5,844.09 - $5,842.65 = $1.43.

The complete question is -

Tammy sold a diamond ring for $10,000. She placed half of the money into a cd with a 3. 9% interest rate compounded daily. She placed the other half into a cd with the same interest rate but compounded monthly. What is the difference in the interest earned on each amount after 4 years?

Answer:

50(1.15)^n-1

Step-by-step explanation:

1. Let's consider the first three terms of g(n) to get a sense of how the function values change as n increases.

2. The first term is Luiza's account balance at the first year of the saving, which is the initial amount she deposited. We know this to be $50.

The second term is Luiza's account balance at the second year. Since the account accumulated 15% each year, it was 1.15 times the balance in the first year, which is $50*1.15=$57.50.

The third term is Luiza's account balance at the third year. Again, this is 1.15 times the balance of the year before that, which is $57.50*1.15=$66.125.

To summarize:

g(1)=50   g(2)=50*1.15   g(3)=50*1.15*1.15

We can see that each term is 1.15 times its preceding term. There is a constant ratio between consecutive terms. Therefore, this is a geometric sequence.

3. We can write an explicit formula for this geometric sequence using the form A*B^n-1. In this form,  A,  is the first term and B is the common ratio. What are the appropriate values for our case?

The first term is Luiza's initial deposit, which is $50.

The common ratio corresponds to the percentage of accumulated interest. Since that percentage is 15%, the common ratio is 1.15.

4. In conclusion, g is a geometric sequence.

An explicit formula for the sequence is g(n)=50*1.15^n-1

Note that this solution strategy results in this formula; however, an equally correct solution can be written in other equivalent forms as well.

The confidence interval is 0.039. This means that the value lies between the range of -0.039 and 0.039. Therefore, we can express the confidence interval as the mean plus or minus the margin of error.

This will give us a range in which the true population mean lies.Let's assume that the mean is 0.259. Then the lower limit of the range is given by:Lower limit = 0.259 - 0.039 = 0.22 And the upper limit of the range is given by:Upper limit = 0.259 + 0.039 = 0.298Therefore, the confidence interval is: 0.22 to 0.298Now we can see that option A is the correct answer: 0.259+0.22.

The value of distance d is 240 miles.

The length of the shortest path connecting any two places in physical space is known as their distance.

Classical physics, particularly Newtonian mechanics, uses the term "distance" to refer to this.

Euclidean distance is calculated in coordinate geometry by applying the Pythagorean theorem.

This first section is

Distance = Speed * Time

Distance: (in metres (m), kilometres (km), miles, and feet

Distance: 50 multiplied by 4 equals 200 miles (50 mph; 4 hours).

In the following segment

Distance is 20 miles multiplied by two to get 40 miles (at a speed of 20 mph) in two hours.

240 miles are hence the total distance.

Assuming a six-hour trip, the average speed is 240 divided by six, or 40 miles per hour.

Answer:

(-2, 3)

Step-by-step explanation:

the point B is

B(x,y)

x

AB (A to B) is twice BC ( B to C )

AB is 2 - x. BC is x - (-4)= x + 4

So

2-x=2 (x + 4)

2-x=2x + 8

3x = -6

x = -2

y

(Same logic as above)

AB is -5 -y. BC is u - 7

-5 -y = 2(y - 7)

-5 - y = 2y - 14

3y = 9

y= 3

y-intercept

y-intercept is the value of y when x = 0,

in this case, when x = 0, y = 10, therefore

y-intercept: y = 10

Graph

x' is the mean of all the x-values,  y' is the mean of all the y-values, and n is the number of pairs in the data set.

\(y=b_1x+b_0\)

There is always one straight line that fits the data more accurately than any other, in the sense of minimizing the total of the squared errors, given any set of integers in pairs (apart from the case when all the x-values are the same). The least squares regression line is what it is known as. Additionally, its slope and y-intercept have formulae.

Given a collection of pairs (x,y) of numbers, there is a line \(y=b_1x+b_0\) that best fits the data in the sense of the least squares regression line, its slope is b1 and the y-intercept is b0.

\(b_1=\frac{SS_{xy}}{SS{_xx}}}\\\\and\\\\b_0=y-b_1x\\\\SS_{xx}=\sumx^2-1/n[\sum x]^2\\\\SS_{xy}=\sum{xy}-1/n(\sum x)(\sum y)\)

x' is the mean of all the x-values,  y' is the mean of all the y-values, and n is the number of pairs in the data set.

\(y=b_1x+b_0\)

specifying the least squares regression line is called the least squares regression equation.

Answer:

The value of x is 1

Step-by-step explanation:

Let us solve the question

∵ Δ PQR ≈ Δ FGH

→ From similarity, then their corresponding sides have an equal ratio

∴ \(\frac{PQ}{FG}\) = \(\frac{QR}{GH}\) = \(\frac{PR}{FH}\)

∵ PQ = 3, QR = x + 3, PR = 2

∵ FG = 6, GH = 6x + 2, FH = 4

→ Substitute them in the ratios above

∴ \(\frac{3}{6}\) = \(\frac{x+3}{6x+2}\) = \(\frac{2}{4}\)

→ By using cross multiplication between the first two ratios

∵ 3 × (6x + 2) = 6 × (x + 3)

∴ 3(6x + 2) = 6(x + 3)

∴ 3(6x) + 3(2) = 6(x) + 6(3)

∴ 18x + 6 = 6x + 18

→ Subtract 6x from both sides

∵ 18x - 6x + 6 = 6x - 6x + 18

∴ 12x + 6 = 18

→ Subtract 6 from both sides

∵ 12x + 6 - 6 = 18 - 6

∴ 12x = 12

→ Divide both sides by 12

∴ x = 1
