Answer:

y = 3x + 17

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = 3 , then

y = 3x + c ← is the partial equation

to find c substitute (- 5, 2) , that is x = - 5, y = 2 into the partial equation

2 = - 15 + c ⇒ c = 2 + 15 = 17

y = 3x + 17 ← equation of line

Step-by-step explanation:

After solving the equations we can conclude that each ticket for an adult costs $24 whereas each ticket for a child costs $6.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

So, 2 equations can be formed:

Let a be adults and c be children.

3a + 4c = 96 ...(1)

2a + 3c = 68 ...(2)

Now, take equation (1):

3a + 4c = 96

3a = 96 - 4c

a = 96 - 4c/3

Now, substitute a = 96 - 4c/3 in equation (2):

2a + 3c = 68

2(96 - 4c/3) + 3c = 68

96 - 4c/3 + 3c = 68/2

96 - 4c + 3c = 34*3

-c = 102 - 96

c = $6

Now, substitute c = 6 in equation (1):

3a + 4c = 96

3a + 4(6) = 96

3a + 24 = 96
3a = 96 - 24

3a = 72

a = 72/3

a = $24

Therefore, after solving the equations we can conclude that each ticket for an adult costs $24 whereas each ticket for a child costs $6.

The margin of error for a 95% confidence interval for the true proportion of tongue rollers among students is closest to (d) 0.04

The margin of error is a statistic that describes how much random sampling error there is in survey results.

Given in question,

n = 400

p = 317/400

  = 0.7925

Confidence Level = 95%

                          = 0.95

Formula for margin error, E = [tex]z\sqrt{\frac{p(1-p)}{n} }[/tex]

Confidence level corresponding to 95 % confidence interval, z = 1.96

Therefore,

Margin Error, E = [tex]1.96\sqrt{\frac{0.7925(1-0.7625)}{400} }[/tex]

                         = 0.0397

                         ≈ 0.04

Answer:

The number of students in the seventh grade is 550.

Step-by-step explanation:

To find the number of students in the seventh grade, we need to use the information given in the problem: the number of students in the Environmental Club (11 students) and the percentage of students in the seventh grade that the Environmental Club represents (2%).

We can set up an equation to represent this information:

11 students / 2% = X students / 100%

The left side of the equation represents the number of students in the Environmental Club and the percentage of the seventh grade that they represent. The right side of the equation represents the total number of students in the seventh grade and the percentage that represents the whole.

Since percentages are just fractions with a denominator of 100, we can rewrite the equation as:

11 students / 0.02 = X students / 1

Then, we can use algebraic techniques to solve for X. One way to do this is to cross-multiply:

X = (11 students * 1) / 0.02

= 550 students

Therefore, there are 550 students in the seventh grade.

The smallest possible value of x - y will be -6 when x = -4  and y = 2. The largest possible value of {2x}/{y}  will be 3/2 when x = 6  and y = 8. The largest possible value of x²+y² will be 100 when x = 6  and y = 8.

Given that -4 ≤ x ≤6 and 2≤ y ≤ 8,

The smallest possible value of x - y

⇒ (x - y)

As per the given, the smallest values of x and y are - 4 and 2

So, substitute the values of x = -4  and y = 2 in the expression (x - y)

⇒ - 4 - 2

⇒ - 6

The largest possible value of {2x}/{y}

⇒ {2x}/{y}

As per the given, the largest values of x and y are 6 and 8

So, substitute the values of x = 6  and y = 8 in the expression {2x}/{y}

⇒ 2(6)/8

⇒ 12/8

⇒ 3/2

The largest possible value of x²+y².

⇒ x²+y²

As per the given, the largest values of x and y are 6 and 8

So, substitute the values of x = 6  and y = 8 in the expression x²+y²

⇒ 6²+8²

⇒ 36 + 64

⇒ 100

Functions in mathematics can be compared to the operations of a vending (soda) machine. When you put in a certain amount of money, you can select different types of sodas. Similarly, for functions, we input different numbers and we get new numbers as the result. Domain and range are the main aspects of functions. You can use quarters and one-dollar bills to buy a soda.

The machine will not give you any flavor of the soda if pennies are input. Hence, the domain represents the inputs we can have here, that is, quarters and one-dollar bills. No matter what amount you pay, you won't get a cheeseburger from a soda machine. Thus, the range is the possible outputs we can have here, that is, the flavors of soda in the machine.

Step-by-step explanation:

In the slope-intercept form of the equation of a line (y=mx+b), m equals the slope and b represents the y-intercept.

Answer:

  h(x) = (x -2)(x -2+i)(x -2-i)

Step-by-step explanation:

You want the linear factorization of h(x) = x³ -6x² +13x -10.

A graphing calculator (attachment 2) shows the one positive real root is x = 2. This means (x-2) is a factor.

When we factor that out, we have a quadratic with no real roots. The vertex of its graph at (2, 1) tells us the roots of it are 2±√-1 = 2±i.

Each root p gives rise to a linear factor (x -p), so the factorization is ...

  h(x) = (x -2)(x -2+i)(x -2-i)

The first attachment shows these factors multiply out to give the polynomial h(x).

No, because you gave T a Boolean when T expected a student as its first argument and a course as its second parameter. This will be less formal if.

The expected,

T(‘‘user2012813",‘‘discrete math")=true

However, the function F(x) and A both yield either true or false (y). Thus, you are attempting to assess

T(F(‘‘user2012813"),A(‘‘discrete math"))=T(true, false)= NULL

Only the first formulation makes sense, but after relations are established, these kinds of structures can be used.

Null functions as both a value and a pointer in computer programming. A built-in constant called null has a value of zero. It is the same as how strings in C are terminated with the letter 0.

Null is another possible value for a pointer, and unless the CPU supports a unique bit pattern for a null pointer, it has the same value as zero.

There is not enough evidence to conclude that the population mean life span for Honolulu residents is less than 77 years.

At the null hypothesis, it is tested if there is not enough evidence that the mean life span is less than 77 years, that is:

At the alternative hypothesis, it is tested if there is enough evidence that the mean life span is less than 77 years, that is:

[tex]H_1: \mu < 77[/tex]

We are testing if the mean is less than a value, hence we have a left-tailed test, with 20 - 1 = 19 df and a significance level of 0.05, thus the critical value is of:

t = -1.7291.

The required equation of the line is x - y + 3 = 0 which is parallel to line x-y=5.

A straight line's general equation is y = MX + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis.

On the y-axis, this value c is referred to as the intercept.

The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.

So, the equation of the line will be:

The needed line will have the same slope as the parallel line.

The slope of the parallel line:
x - y = 5

y = x - 5

The parallel line's slope is 1.

Equation of a line with a slope of 1 through the point (-5,-2).
