The number of newly reported crime cases in a county in New York State is shown in the accompanying table, where x represents the number of years since 1995, and y represents number of new cases. Write the linear regression equation that represents this set of data, rounding all coefficients to the nearest hundredth. Using this equation, estimate the calendar year in which the number of new cases would reach 887.

Answers

Answer 1

The linear regression equation that represents the given set of data is y=0.2x+865.

What is linear regression?

Linear regression is a linear approach for modelling the relationship between a scalar response and one or more explanatory variables. The case of one explanatory variable is called simple linear regression; for more than one, the process is called multiple linear regression.

The line of best fit is in the form y=bx+a

The slope is b= [tex]\frac{\sum (x-\bar x)\sum (y-\bar y)}{\sum (x-\bar x)^2}[/tex]

Here, [tex]\bar x[/tex] =(0+1+2+3+4)/5

= 1.8

[tex]\bar y[/tex] = (856+871+924+961+961)/5

= 914.6

∑(x-[tex]\bar x[/tex])=(0-2.5)+(1-2.5)+(2-2.5)+(3-2.5)+(4-2.5)

= -2.5-1.5-0.5+0.5+1.5

= -2.5

∑(y- [tex]\bar y[/tex]) =(865-914.6)+(871-914.6)+(924-914.6)+(961-914.6)+(961-914.6)

= -49.6-43.6+9.4+46.4+46.4

= 9

So, slope b= 1.8×9/9²

b=0.2

Substitute b=0.2 and (0, 865) in y=bx+a, we get

865=0.2×0+a

a=865

Substitute b=0.2 and a=865 in y=bx+a, we get

y=0.2x+865

Therefore, the linear regression equation that represents the given set of data is y=0.2x+865.

Marcelle and Megan realized that they could express their ages more specifically if they used fractions. Doing this will allow them to calculate their difference in their ages. Marcelle is $15\frac{1}{2}$ years old, and Megan is $7\frac{7}{12}$. What is the difference in their ages? Express your answer as a simplified mixed number.

Answers

The difference in ages of Marcelle and Megan is 95/12 as an improper fraction and as a mixed number is 7 whole number and the fraction 11/12.

How to evaluate the difference in the fraction of the ages

We shall convert the fractions to have similar denominators and simply apply subtraction for the numerators as follows:

Marcelle's age = 15 whole number, 1/2

Marcelle's age = 31/2

Megan's age = 7 whole number, 7/12

Megan's age = 91/12

LCM of 2 and 12 is 12 so;

Marcelle's age = 31/2 × 12/12

Marcelle's age = 186/12

difference in their age (186 - 91)/12

difference in their age = 95/12

Therefore, the difference in the ages of Marcelle and Megan is the fraction 95/12 or as a mixed number is 7 whole number and the fraction 11/12

C. 1/28

D. 1/22

Answers

The probability of selecting one banana, then one apple, then one orange, in that order, from the basket if you are blindfolded is 1/22.

What is the probability:

The probability of an event occurring is defined by probability. There are many instances in real life where we may need to make predictions about how something will turn out.

The outcome of an event may be known to us or unknown to us. When this happens, we indicate that there is a probability that the event will happen or not.

It is also defined as the ratio of the number of favorable outcomes to the total number of outcomes.

The formula for the probability of an event is given by

P(E) = No of favorable outcomes/ Total No of outcomes ]

Here we have

A basket of fruit contains 4 bananas, 3 apples, and 5 oranges.

Total number of fruits = 4 + 3 + 5 = 12

By the given formula,

Probability of selecting 1 banana = 4/12 = 1/3

Probability of selecting 1 apple = 3/12 = 1/4

Probability of selecting 1 orange = 5/12

The order of the fruits that is given is 1 banana, then 1 apple, then 1 orange

Let's assume that,

We taken 1 banana

=> The probability of selecting one banana = 1/3

After taking one banana, remaining fruits = 12 - 1 = 11

Now we have drawn 1 apple

=> The probability of selecting one apple in 11 fruits = 3/11

After taking one apple remaining fruits = 11 - 1 = 10

=> The probability of selecting one orange from 10 fruits = 5/10 = 1/2

From the above calculations,

The probability of selecting in given order = (1/3)(3/11)(1/2) = 3/66 = 1/22

Therefore,

The probability of selecting one banana, then one apple, then one orange, in that order, from the basket if you are blindfolded is 1/22.

What is the equation of a line with a slope of 3 and y-intercept equal to 5?

Answers

The equation of a line is given by y = mx + b, where m is the slope and b is the y-intercept. Given that the slope is 3 and the y-intercept is 5, the equation of the line is y = 3x + 5.

The equation of a line is a mathematical expression of the form y = mx + b, where m is the slope and b is the y-intercept. This equation can be used to describe the relationship between the x-coordinate and y-coordinate of points on a line. In this specific equation, the slope is 3 and the y-intercept is 5, which means that the line passes through the point (0, 5) and has a slope of 3. Substituting 3 for m and 5 for b in the equation, we get y = 3x + 5, which is the equation of the line with a slope of 3 and a y-intercept of 5. We can use this equation to determine the y-coordinate of any given point on the line, provided we know the x-coordinate of the point.

Define percentage.

A percentage (%) is a number that can alternatively be written as a decimal or fraction and represents a quantity as a proportion of 100. You can change a percentage to a fraction by putting 100 in the numerator and also the percentage number in the numerator.

Here,

Becky will need to blend several substances to obtain the necessary level of protein in order to generate 28 grams of a material that is 30% protein.

Let's name the first ingredient's percentage of protein (50%) "x" and the second ingredient's percentage of protein (25%) "y".

That which we are aware of is

28 grams of the combination are present in total.

It has 30% protein.

50% of the first component is protein.

25% protein makes up the second component.

To express the issue, we can build up the following equations:

x + y = 28 (the total amount of the mixture is 28 grams) (the total amount of the mixture is 28 grams)

(0.50)x + (0.25)y = 0.30(28) (the mixture is 30% protein)

Now we can use the first equation to solve for one variable in terms of the other. If we solve for y, we get:

y = 28 - x

We can substitute this into the second equation:

(0.50)x + (0.25)y = 0.30(28) (28) (30% of the mixture is protein)

We may now solve for one variable in terms of the other using the first equation. If we figure out y, we obtain:

y = 28 - x

This can be used as a substitution in the second equation:

(0.50)x + (0.25)(28-x) = 0.30(28) (28)

which results in:

0.50x + 7 - 0.25x = 8.4

And simplifying even more

0.25x = 0.6

x = 2.4

We now know that 2.4 grams of the combination are made up of the first component, which is 50% protein. Using this knowledge, we can calculate the quantity of the second ingredient:

y=28 - x=28 - 2.4=25.6 grams

Answers

The numbers in the arrangement can be represented by x, y, z, a, b, c and d, where x is at the top and d is at the bottom. The relationship between the numbers is as follows:

x = y - z

y = a - b

z = c - d

We can use this information to find the values of z, c, and d in terms of x, y, and a:

z = y - x

c = z + d

d = z - c

Since we are looking for the four greatest distinct possible values for z, we can assume that x, y, and a are as small as possible (i.e. 0) and c and d are as large as possible.

Thus, the four greatest distinct possible values for z are:

z = y - x = 0 - 0 = 0

z = a - y = 0 - 0 = 0

z = c - d = c

z = c - d = d

To solve the inequality -7x < 35, we first need to isolate the variable (x) on one side of the inequality.

We will divide both sides of the inequality by -7 (since -7 is being multiplied by x on the left side).

However, when we divide or multiply both sides of an inequality by a negative number, we must reverse the inequality symbol. So the inequality becomes:

x > -5

This inequality can be read as "x is greater than -5." It is the solution set of all real numbers x that is greater than -5.

How do you start elimination with 3 variables?

Answers

The goal of elimination is to remove one of the variables by combining the equations together.

Let's say we have an equation with 3 variables:

a + b + c = 0

The goal of elimination is to remove one of the variables by combining the equations together.

Multiply the first equation by a number, n, such that nb + nc = 0

For example:

Let n = -2

-2b + -2c = 0

Add the two equations:

a + b + c = 0

-2b + -2c = 0

a - b = 0

Solve for b:

a - b = 0

b = a

Therefore, the final equation is:

a + a + c = 0

2a + c = 0

What is the 3 variable?

Answers

A three-variable system is a system of equations or inequalities involving three variables.

The three variables could refer to any three related quantities, such as a person's age, height, and weight. In a three-variable system, the number of equations is equal to the number of variables, so three equations are needed to solve the system. Each equation in the system will involve all three variables and will be solved through a combination of algebraic manipulation, substitution, and elimination techniques. Once all three equations have been solved, the values of the variables can be found.
