The equation of the line with slope -1/7 is (y-3) = -1/7(x-3).

According to the question,

We have the following information:

Slope of the line = -1/7

Points through which line is passing = (3,3)

We know that the following formula is used to find the equation of the line:

(y-y') = m(x-x') where m is the slope of the line

In this case, we have x' = 3 and y' = 3.

(y-3) = -1/7(x-3)

This expression can be solved further by multiplying -1/7 into the bracket and then by moving 3 from the left hand side to the right hand side. Then this equation will be in slope-intercept form.

Hence, the correct option is B.

As per given data of living children under 18 years of age , percent of children whose age is under 18 years lived with their mother only is equal to 39.3%.

As given in the question,

Let us consider 100% be the total percent representing the living status of children under 18 years of age

Given:

Percent of children living with both the parents = 49.2%

Percent of children living with only father = 8%

Percent of children living with neither of the parents = 3.5%

Let us consider percent of children living with only mother = x%

Required equation is:

( x + 49.2 + 8 + 3.5 )% = 100%

⇒ x + 60.7% = 100%

⇒ x = 100 - 60.7

⇒ x = 39.3%

Therefore, for the given data of living children under 18 years of age , percent of children whose age is under 18 years lived with their mother only is equal to 39.3%.

What is residual?

A residual in statistics is the discrepancy between an observed value and a value that was predicted.

Typically, the anticipated value is based on a model, like a linear regression model. The prediction error is represented by a residual, which can be either positive or negative. A positive residual indicates a difference between the observed and expected values, whereas a negative residual indicates the opposite. Specifically, the residual's absolute value is the distance between the observed value and the predicted value.

For evaluating a model's correctness, residuals are crucial. The residuals should be randomly distributed in the vicinity of zero if the model is valid. The residuals will be biased either in favor of or against the null hypothesis if the model is not accurate. A model's goodness of fit can also be evaluated using the residual. Relatively small residuals characterize a model with a high goodness of fit. Remainders that are far from zero will be present in a model with a low goodness of fit.

Domain: {-1,0,1,4}

Range: {3,5,35}

Step-by-step explanation:

The domain is the set of x values while range is the set of y values

Here, the set of x values would be -1 , 0 , 1 and 4

And the y values would be 5, 3, 5, and 35

When writing the domain and range, you put the values into brackets "{}" and put them in order from least to greatest. Also if there are repeated values you do not repeat them, you only put them once.

This means that the domain would be {-1,0,1,4}

And the range would be {3,5,35}

34 students red is their favorite color

2 out of 7 of the pupils in year 9 say their favourite colour is red

Fraction of pupil that say red is their favorite colour is 7/9

There are 119 pupils in year 9

We need to calculate the number of students out of 119 that would say that their favourite colour is red

To find that,

we multiply the fraction of students that like red with the total number of students

2/7 * 119

= 34

Therefore, if 2 out of 7 of the pupils in year 9 say their favourite colour is red. Then 34 out of 119 pupil will say that their favourite colour is red.

If Lines J and k are perpendicular. The slope of line k is 3, the slope of line j is -1/3

When two lines are perpendicular to each other, the product of their slope results in -1

slope of line j x slope of line k = -1

slope of line j x 3 = -1

From the data in the table relating time and depth, we have that:

a) The scatter plot is graphed at the end of the answer.

b) The scatter plot has negative correlation.

c) The estimate for the depth at a time of 15 seconds is of 50.37 cm.

The scatter plot is built inserting all the points of the table in a graph, which are in the following format:

(Time in seconds, Depth in cm).

Hence the scatter plot will be composed by a set of points, without an image, as is shown at the end of the answer.

The points from the table are listed as follows:

(2, 47), (4, 41), (6, 38), (8, 37), (10, 32), (12, 24), (14, 20), (16, 19).

As the input variable time increases, the output variable depth decreases, meaning that the points in the scatter plot also follow the format of a decreasing line, hence there is negative correlation in the scatter plot.

These points are also inserted into a linear regression calculator to built the line of best fit, which is defined as follows:

y = -2.07x + 50.89.

At 15 seconds, the estimate is obtained replacing the lone instance of x in the equation by 15, hence:

y = -2.07 x 0.25 + 50.89 = 50.37 cm.

The sum of consecutive odd cubes of 8128 is 1³+3³+5³+7³+9³+11³+13³+15³

Therefore, 1+27+125+343+729+1331+2197+3375=8128

Consecutive numbers are those that come after each other in descending order from the smallest to the largest. The difference between consecutive numbers is always fixed and follows a predictable pattern. For example, the first three consecutive natural numbers are 1, 2, 3. The simplest way to find consecutive numbers is to look at the number set and find the number that is either before or after the term of interest.

We know that consecutive odd numbers are 1,3,5,7,9,11,13,15,17..

Here 8128 is a perfect square

And it can be written as the sum of consecutive odd cubes as follows:

1³=1

3³=27

5³=125

7³=343

9³=729

11³=1331

13³=2197

15³=3375

The sum of consecutive odd cubes of 8128 is

=1³+3³+5³+7³+9³+11³+13³+15³

=1+27+125+343+729+1331+2197+3375

The zeros of the function are-

The given expression is-

f(x)=(x-10)^2-49

To find the zero put f(x) = 0.

(x-10)^2-49 = 0

Including both sides of an equation, add 49.

(x-10)^2 - 49 + 49 = 49

(x-10)^2  = 49

To remove the exponent upon that left side of the equation, take the appropriate root of both sides.

x - 10 = ±√49

x - 10 = ±7

Solve each case;

a:  x - 10 = + 7

x = 7 + 10

x = 17 (greatest number)
