17) Tony is retiring after 40 years and will receive a monthly pension of $1400
and Social Security of $1100 a month. What will be Tony's total annual
income?

Answer:

Ratio = [tex]\frac{Perfect.squares}{non.Perfect.squares}[/tex] = [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

The perfect squares from 1-30 are:

1, 4, 9, 16, 25

Total no. of perfect squares = five =5

Total no. of non perfect squares = 30-5 = 25

Ratio =[tex]\frac{Perfect.squares}{non.Perfect.squares}[/tex] = 5 / 25 = [tex]\frac{1}{5}[/tex]

The ratio of perfect squares to non-perfect squares for the numbers 1 to 30 is 1:5.

A perfect square is a number that is the square of an integer. For the numbers 1 to 30, the perfect squares are 1, 4, 9, 16, 25, as these numbers are squares of integers 1, 2, 3, 4, 5 respectively. The number of perfect squares is 5.

The total number of tiles is 30. So the number of non-perfect squares is 30 - 5 = 25.

The ratio of perfect squares to non-perfect squares in simplest form, then, is 5 : 25. Simplified, this ratio is 1 : 5.

The questions pertain to the analysis of linear relationships between variables using scatter plots, lines of best fit through linear regression, and understanding correlation coefficients to identify the strength and direction of relationships in data.

The questions provided are centered around the concepts of linear equations, scatter plots, correlation, and regression analysis in the realm of mathematics. Scatter plots are graphical representations showing the relationship between two variables. In these types of questions, the independent variable is plotted on the x-axis, and the dependent variable is plotted on the y-axis. To analyze the relationship, one can use linear regression to find the line of best fit, which is a straight line that best represents the data on a scatter plot. The correlation coefficient, often denoted as r, indicates the strength and direction of the linear relationship between two variables.

The line of best fit can be found by calculating the least-squares line, which minimizes the sum of the squares of the vertical distances of the points from the line. The equation of this line is typically in the form y = a + bx, where 'a' is the y-intercept and 'b' is the slope. The slope indicates how much the dependent variable changes for a one-unit change in the independent variable. The y-intercept is the value of the dependent variable when the independent variable is zero. A correlation coefficient of zero implies no linear relationship between the variables.

When looking at data such as stock market trends or health-related measurements like BMI and cholesterol, understanding the strength and type of correlation is essential for making predictions. For example, a positive correlation indicates that as one variable increases, the other variable tends to increase, while a negative correlation indicates the opposite. It's important to note that correlation does not imply causation; just because two variables are correlated does not mean that one causes the other.

The expression will be  y =8*2 or y = (48/6)*2

Step-by-step explanation:

The direct proportion is given if y varied directly as x

y∝x

When the proprtionality symbol is removed, a proportionality constant is introduced.

y = kx

as we know y = 48 when x = 6

[tex]48 = k * 6\\k = \frac{48}{6}\\k = 8[/tex]

The equation will be:

y = 8x

So when x=2

y = 8*2

y = 16

Hence,

The expression will be  y =8*2 or y = (48/6)*2

To find the value of y when x is 2 in a direct variation, use the constant of variation k found from the given values (y = 48 when x = 6), which is 8 in this case, and multiply it by 2 to get y = 16.

If y varies directly as x, this means that y can be expressed as y = kx, where k is the constant of variation. Given that y = 48 when x = 6, we can find the value of k by substituting these values into the direct variation equation:

k = y/x = 48/6 = 8

Now that we have k, we can find the value of y when x is 2:

y = kx = 8 x 2 = 16

Therefore, the expression to find the value of y when x is 2 is y = 8 x 2.

Answer:

The price of a senior ticket is $12.

Step-by-step explanation:

Given:

Mr. Smith purchased 8 senior tickets and 5 child tickets for $136. Mr. Jackson purchased 4 senior tickets and 6 child tickets for $96.

Now, to get what is the price of a senior ticket.

Let the senior ticket be [tex]x[/tex] and the child ticket be [tex]y[/tex]:

So, according to question

[tex]8x+5y=136[/tex].........(1)

[tex]4x+6y=96[/tex]...........(2)

Now, we have system of equations:

Multiplying the equation (2) by -2 we get:

[tex]-8x-12y=-192[/tex].......(3)

Now, adding the equation (3) and (1) the variables and the numbers:

[tex]-8x-12y+8x+5y=-192+136[/tex]

[tex]-7y=-56[/tex]

Dividing both sides by -7 we get:

[tex]y=8[/tex]

Putting the value of y in equation (2) we get:

[tex]4x+6(8)=96[/tex]

[tex]4x+48=96[/tex]

On solving the equation we get:

[tex]x=12[/tex].

Therefore, the price of a senior ticket is $12.

Answer:

The missing part is given below.

500=(2xL)+(__2__x_90___)

500=2L+__180_____

_320__=2L

_320____ divided by 2=L

_160____=L

Step-by-step explanation:

Given:

Perimeter of Rectangle = 500 feet

Width = 90 feet

Length = L

Solution:

[tex]\textrm{Perimeter of Rectangle} = 2(Length + Width)\\\\\textrm{On substituting the given values in it we get}\\500 = 2\times L + 2\times 90\\\\500 - 180 =2\times L\\320 =2\times L\\\\\frac{320}{2}=L\ ....................... (\textrm{320 divided by 2}) \\160 = L[/tex]

Final answer:

To find the length of the garden, the formula for the perimeter of a rectangle is used (P = 2L + 2W), where the perimeter is 500 feet and the width is 90 feet. By substituting these values and solving for L, we find that the length of the garden is 160 feet.

Explanation:

Finding the Length of a Garden

To find the length of a rectangular garden when you know the perimeter and the width, you can use the formula for the perimeter of a rectangle, which is P = 2L + 2W, where P stands for the perimeter, L is the length, and W is the width. The student has provided that the width (W) of the garden is 90 feet and the perimeter (P) is 500 feet.

Substituting the values we know into the formula, we get:

500 = 2L + 2(90)

Now, we solve for the length (L) by following these steps:

First, do the multiplication: 500 = 2L + 180

Next, subtract 180 from both sides to isolate the term with L: 320 = 2L

Finally, divide both sides by 2 to solve for L: 160 = L

Therefore, the length of the garden is 160 feet.

Answer:

[tex]A_{5} = 1875[/tex]

Step-by-step explanation:

The geometric sequence is represented by

[tex]A_{n} = 5 \times A_{n - 1}[/tex] .......... (1) and [tex]A_{1} = 3[/tex]

So, [tex]A_{2} = 5 \times A_{2 - 1} = 5 \times A_{1} = 5 \times 3 = 15[/tex]

{Putting n = 2}

Again, putting n = 3 in equation (1), we get

[tex]A_{3} = 5 \times A_{2} = 5 \times 15 = 75[/tex]

Again, putting n = 4 in equation (1), we get

[tex]A_{4} = 5 \times A_{3} = 5 \times 75 = 375[/tex]

Again, putting n = 5 in equation (1), we get

[tex]A_{5} = 5 \times A_{4} = 5 \times 375 = 1875[/tex] (Answer)

Answer:20652.00

Step-by-step explanation:

The formula would be p*r*t

p is the principal which is amount of money before interest

r is the interest rate

t is time period

so it would be 57,366.66*9 2/5%*4

9 2/5 as a decimal would be 9.4 or 0.09

57,366.66*9.4=539246.604*4=2156986.416

The correct amount would be $20652.00 in 4 years

Use 0.09  when u multiply instead of 9.4 because it is much easier

The closed linear form of sequence 3, 4, 5, 6, 7, .. is a = 3 + n

Option C

Solution:

Given Sequence is 3, 4, 5, 6, 7, ...

Let us the check the each option which can form the above sequence

a) a= 2n

[tex]\begin{array}{l}{\text {For } n=0, a=2 \times(0)=0} \\\\ {\text {For } n=1, a=2 \times(1)=2} \\\\ {\text {For } n=2, a=2 \times(2)=4}\end{array}[/tex]

We get a sequence 0, 2, 4 which does not satisfy the given sequence

b) a= 2-n

[tex]\begin{array}{l}{\text {For } n=0, a=2-0=2} \\\\ {\text {For } n=1, a=2-1=1} \\\\ {\text {For } n=2, a=2-2=0}\end{array}[/tex]

We get a sequence 2, 1, 0 which does not satisfy the given sequence

c) a= 3+n

For n = 0, a = 3 + 0  = 3

For n = 1, a = 3 + 1  = 4

For n = 2, a = 3 + 2 = 5

For n = 3 , a = 3 + 3 = 6

For n = 4, a = 3 + 4 = 7

Which satisfy the given sequence

Hence, c) is the correct option

The closed linear form of the sequence 3, 4, 5, 6, 7, ... is a = 3 + n, which matches option C. The pattern in the sequence indicates that the nth term can be expressed as 3 + (n - 1). Therefore, the answer is option A: a = 2 + n.

To find the closed linear form, we identify the pattern in the sequence. The sequence starts at 3 and increments by 1 for each subsequent term. Hence, the nth term (an) can be expressed as:

an = 3 + (n - 1)

an = 2 + n

Therefore, the closed linear form of the given sequence is option A: a = 2 + n.

Total cost of tickets for one movie showing is calculated by multiplying the total number of seats (n rows times m seats per row) by the cost per ticket, which is $5.60.

To calculate the total cost of all tickets for one movie showing in a theater with n rows and m seats per row, you'll need to use multiplication to find the total number of seats and then multiply it by the cost per ticket. Here is a step-by-step guide:

For example, if a theater has 10 rows with 20 seats in each row, the total number of seats is 10 × 20 = 200. The total cost for all tickets would then be 200 × $5.60 = $1120.

It’s 35 because 9*5 is 45 and 80-45 is 35

The final factored expression using the GCF is: 14x+63=7(2x+9)

To factor the expression 14x + 63 using the Greatest Common Factor (GCF), let's first find the GCF of the numerical coefficients 14 and 63. The largest number that divides both 14 and 63 without a remainder is 7, making it the GCF.

Next, we divide each term by the GCF:

14x divided by 7 is 2x

63 divided by 7 is 9

Now that we have divided each term by the GCF, we can write the original expression as a product of the GCF and the simplified expression:

14x + 63 = 7(2x + 9)

This expression is fully factored as the product of the GCF (7) and the binomial (2x + 9).
