To determine the number you thought of, let's work backward from the given result of 156. We determined that the number you thought of was 490.

By following the steps in reverse order, we can calculate the original number. We start with the given result of 156. To reverse the subtraction, we add 7 18 to it, which gives us 8 7 4. Moving further, to reverse the division, we multiply 8 7 4 by 1 1 5, resulting in 1 0 0 5 6 0. Now, to reverse the multiplication, we divide 1 0 0 5 6 0 by 2 1 2, yielding 4 9 0. Hence, the number you initially thought of was 4 9 0.

In summary, by working backward from the given result of 156, we determined that the number you thought of was 490.

Thus, the correct statement is B: The speed of Becca's car is more.

An indicator of how 1 quantity changes in proportion to another is called a rate of change. Positive or negative change rates are possible. This is equivalent to a change in the y-value in between two data points. Zero rate of change refers to a quantity that does not fluctuate over time.

Relation between speed and time:

speed = distance/ time

Tom's car:

distance d = 120 miles

Time t = 3 hours

speed of Tom's car = 120/3 = 40 miles/hours

Becca's car:

distance d = 90 miles

Time t = 2 hours

speed of Becca's car = 90/2 = 45 miles/hours

The researcher can use certain formulas for finding confidence intervals and hypothesis testing in this scenario.

For confidence intervals, the formula for the mean difference would be used, which is the average of the weight changes in the sample.

This formula calculates the range within which the true population mean difference is likely to fall.

To conduct hypothesis testing, the researcher can use the formula for the t-test for a single sample.

This test compares the mean difference observed in the sample to a hypothesized value and determines whether there is enough evidence to support or reject the hypothesis.

To check the assumptions necessary for this test, the researcher would need additional information. The assumptions typically include:

1. Random sampling: It is important to ensure that the subjects were randomly selected from the population to generalize the results.

2. Normality: The weight changes should follow a normal distribution within the population.

The researcher would need to assess the normality assumption, such as by examining the distribution of weight changes or using statistical tests like the Shapiro-Wilk test.

3. Independence: The weight changes of one subject should not be influenced by the weight changes of another subject.

This assumption can be violated if the subjects are related or if there are repeated measurements on the same subjects.

By checking these assumptions and using the appropriate formulas, the researcher can make confidence intervals and perform hypothesis testing to draw conclusions about the effects of the drug on weight loss in the population.

Answer:

Total cost = $14464

Step-by-step explanation:

Step 1:  Multiply the discount percentage by the regular price to determine the discount amount:

0.20 * 16000 = 3200

Thus, the 20% discount lowers the regular price by $3200.

Step 2:  Subtract the discount amount from the regular price to determine the new price:

16000 - 3200 = 12800.

Thus, the subtotal is $12800

Step 3:  Multiply tax percentage by subtotal to determine tax:

0.13 * 12800 = 1664

Thus, the 13% tax rate would raise the subtotal by $1664.

Step 4:  Add the tax to the subtotal to find the cost price.

1664 + 12800 = 14464.

Thus, the total cost of the car is $14464.

Thus, the total cost of the car with the 20% discount and the 13% tax is 14464.

Length = 171 yards

Step-by-step explanation:

given data

length of the field = 5 yards

Perimeter of the rectangular field = 430 yards.

solution

we consider here length of the field = L

and width of the field = W

as we know length of the field 5yards less than quadruple the width

so here

L = 4W - 5       .....................................1

and  

Perimeter (P) will be here

P = 2(L + W)      ............................................2

put here equation 1 value

430 = 2(4W - 5 + W)  

solve it we get

W = 44

so here put value in eq 1 we het

L = 4W - 5          

L = 4(44) - 5

L = 171

so, length of the field is 171 yards

To determine the concentration of the analyte in the unknown using the fit parameters and the linear model, you need to substitute the given signal value into the equation y = mx + b.

In this case, the linear model is represented by the equation y = mx + b, where:

y is the signal value (80.77 in this case),

m is the slope obtained from the regression analysis, and

b is the y-intercept obtained from the regression analysis.

You haven't provided the values of m and b, so I'll use placeholders for now.

Let's assume the slope (m) obtained from the LINEST formula is m = 2.5 and the y-intercept (b) is b = 10.

Substituting these values into the equation:

y = mx + b

80.77 = 2.5x + 10

To find the concentration (x), we can rearrange the equation:

2.5x = 80.77 - 10

2.5x = 70.77

x = 70.77 / 2.5

x ≈ 28.31

Therefore, based on the given fit parameters and the linear model, the concentration of the analyte in the unknown is approximately 28.31 ppm Co2+.

Both A1 and A2 belong to W, and they are linearly independent, so they form a basis for W.

1. To find a basis for W = {A: a + b + c + d = 0}, we can start by writing a general matrix in W as:

A =
[ r  a  b ]
[ c  -r -a ]

where r is a free parameter. Then we can rewrite the condition a + b + c + d = 0 as:

a = -b - c - d

Substituting this into the matrix A, we get:

A =
[ r  -b -c -d ]
[ c  -r  b  c ]

Now we can see that the matrix A has two free parameters (r and d), and the remaining entries are determined by b and c. We can choose b = 1 and c = 0 to get:

A1 =
[ r  -1  0  -r ]
[ 0  -r  1   0 ]

and we can choose b = 0 and c = 1 to get:

A2 =
[ r  0  -1   r ]
[ 1  -r  0   0 ]

Both A1 and A2 belong to W, and they are linearly independent, so they form a basis for W.

2. To find a basis for W = {A: a = -d, b = 2d, c = -3d}, we can write a general matrix in W as:

A =
[ r  2d  -3d ]
[-d  -r  d   ]

where r is a free parameter. Then we can see that the matrix A has one free parameter (d), and the remaining entries are determined by r. We can choose d = 1 to get:

A1 =
[ r  2  -3 ]
[-1 -r  1 ]

and we can choose d = 0 to get:

A2 =
[ r  0  0 ]
[ 0 -r  0 ]

Both A1 and A2 belong to W, and they are linearly independent, so they form a basis for W.

3. To find a basis for W = {A: a = 0}, we can write a general matrix in W as:

A =
[ 0  b ]
[ c  d ]

where b, c, and d are free parameters. Then we can see that the matrix A has two free parameters (b and d), and the remaining entries are determined by c. We can choose b = 1 and d = 0 to get:

A1 =
[ 0  1 ]
[ c  0 ]

and we can choose b = 0 and d = 1 to get:

A2 =
[ 0  0 ]
[ c  1 ]

Both A1 and A2 belong to W, and they are linearly independent, so they form a basis for W.

4. To find a basis for W = {A: b = a - c, d = 2a + c}, we can write a general matrix in W as:

A =
[ a  a - c ]
[ c  2a + c ]

where a and c are free parameters. Then we can see that the matrix A has two free parameters (a and c), and the remaining entries are determined by these parameters. We can choose a = 1 and c = 0 to get:

A1 =
[ 1  1 ]
[ 0  2 ]

and we can choose a = 0 and c = 1 to get:

A2 =
[ 0  -1 ]
[ 1  1 ]

Given is that Aiko works in the fish department of a pet store. She must drain, clean, and refill two reef tanks. The first tank hold 175 gallons of water and drains at a rate of 25 gallons per hour. The second tank holds 200 gallons of water and drains at a rate of 30 gallons per hour.

Equation for tank {1} -

y = 175 - 25x

Equation for tank {2} -

y = 200 - 30x

For the solution we can write -

175 - 25x = 200 - 30x

- 25x + 30x = 200 - 175

5x = 25

x = 5

and

y = 200 - 150

y = 50

For the same amount of water we can write -

175 - 25x = 200 - 30x

- 25x + 30x = 200 - 175

5x = 25

x = 5 hours

In tank (1), there is : 175 - 25 x 5 = 50 gallons

slope 2/6 = 1/3

y-int= -5

Answer:

y=x-1

Step-by-step explanation:

Hi there!

We want to find the equation of the line that passes through the points (7, 6) and (-2, -3)

There are 3 ways to write the equation of the line:

The most common (and usually, the easiest way) would be slope-intercept form, so let's write it that way

First, we'll need to find the slope of the line

The slope can be found using the formula \(\frac{y_2-y_1}{x_2-x_1}\), where \((x_1, y_1)\) and \((x_2, y_2)\) are points

We have two points, which is needed, but let's label their values in order to avoid any confusion:

\(x_1= 7\\y_1=6\\x_2=-2\\y_2=-3\)

Now substitute these values into the formula to find the slope (m):

m=\(\frac{y_2-y_1}{x_2-x_1}\)

m=\(\frac{-3-6}{-2-7}\)

Subtract the numbers

m=\(\frac{-9}{-9}\)

Divide

m=1

The slope of the line is 1

So far, we can write the equation of the line as this:

y=1x+b, or y=x+b

We'll need to find b

As the equation passes through both (7,6) and (-2, -3), we can use either one of them to solve for b

Taking (7, 6) for instance, substitute 7 as x and 6 as y:

6=1(7)+b

Multiply

6=7+b

Subtract 7 from both sides

-1=b

Now substitute -1 as b:

y=x-1

Hope this helps!
