The fare for 47 miles is $32.9

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

Total miles= 36  miles

Total fare = 25.20

fare for 1 miles

= 25.20/36

=0.7

Now, for 47 miles the fare will be

=0.7*47

=$32.9

Hence, the fare for 47 miles is $32.9

7 - 0 = 7/5(0 - (-5)) is the equation in slope intercept form for the line passes through points (-5,0) and (0,7).

A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.

The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.  

Therefore,

m =  y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.

Be aware that tan ∅ = y/x

We also refer to this tan as the line's slope.

We have been asked  to write an equation of the line in point-slope form

of a  line which passes through (-5,0) and (0,7)

We know that  point-slope form = y₂ - y₁ = m(x₂ - x₁)

But first we will find slope(m)

We know that slope = m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

For the pairs of points (-5,0) and (0,7)

⇒ m = [tex]\frac{7- 0}{0 - (-5)}[/tex]

⇒ m = [tex]\frac{7}{5}[/tex]

⇒ m = 7/5

After we substitute the given information we get

7 - 0 = 7/5(0 - (-5))

Answer:

relation

Step-by-step explanation:

To be a function each element from set x has only one unique element in y.

In our case x = 0 has two outcomes y = 1 and y = 3, so is a relation.

f(x) = y

f(-2) = 5

f(0) = 1  and f(0) = 3

f(5) = 8

f(7) = 5

Some memory aids:

Think about if we count how many likes we got on a social media post at the end of the day, then we can not have different numbers for same post yet we can have the same number of likes on different posts to be a function.

f(post 0) = 1  like  and f(post 0) = 3 likes ❌ not a function because same post has different numbers of likes at the end of the day -not possible

f(post -2) = 5 likes and f(post 7) = 5 likes ✅ could be a function because different posts can have the same number of likes at the end of the day

Explanation:

The number 1 is spelled as "one", which clearly has an "e" in it. This contradicts the original statement that we don't need this letter.

The other numbers of 6 (six), 2 (two), and 4 (four) don't involve "e"s at all. So they can be ruled out.

The probability that each of the balls will be; a) P( of the same color) = 0.08875. b) P ( of different color) = 0.247678

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

The Number of red balls = 5

The number of blue balls = 6

The number of green balls = 8

The Total number of balls = 5 + 6 + 8 = 19

Then with three balls selected at random, by using combination method ;

nCr = n!/(n-r)!r!

a) P( of the same color) = 5C3 + 6C3 + 8C3 / 19C3

=  86/969 = 0.08875

b) P ( of different color) = 5C1 X 6C1 X 8C1 /19C3

= 240/969 = 0.247678

Hence, The probability that each of the balls will be; a) P( of the same color) = 0.08875. b) P ( of different color) = 0.247678

Used AI:R Math, snap a picture of a math question and tutors will solve it for free in a matter of minutes.

Answer:

If the student is female then the probability that the student will participate is about 67%

If the student is male the probability that they participate is about 33%

Step-by-step explanation:

It is given that 48% of the students in the school are male. That means that the remaining students in this school are (for the sack of this problem) female out 100% of students. You would subtract 48% from 100% which is 52% which is the percentage of students in the school who are female.

From this point you need to find the percentage of students who would participated in the survey. To do that you would divide the number of the type of student who did the survey by the type of student in the school. For example for the male you would divide 16% from 48% or 16 ÷ 48 which would equal to the proposed of males who would participate which is about 33% of males. You would do the same math for finding the probability of females so it would be 35 ÷ 52 which is about 67% of females.

Even though the random student is more likely to be female the chances of the gender of the student is almost 50%/50% because if you round it to the nearest tenth it would be 50.

The values of functions are as follows:

g(-6) = -6

g(0) = 5

g(7) = 8

h(-6) = 10

h(0) = -1

h(7) = -4

Given, that function g(x) = f(x)/3 and function h(x) = -g(x) + 4

Now to calculate the function values on different values of x.

g(x) = f(x)/3

h(x) = -g(x) + 4

1 )

When x = -6

f(-6) = -18

g(-6) = f(-6)/3

g(-6) = -18/3

g(-6) = -6

h(-6) = -g(-6) + 4

h(-6) = 6 + 4

h(-6) = 10

2)

When x = 0

f(0) = 15

g(0) = f(0)/3

g(0) = 15/3

g(0) = 5

h(0) = -g(0) + 4

h(0) = -5 + 4

h(0) = -1

3)

When x = 7

f(7) = 24

g(7) = f(7)/3

g(7) = 24/3

g(7) = 8

h(7) = -g(7) + 4

h(7) = -8 + 4

An equation is a mathematical statement that compares two mathematical expressions by equating them  and on both sides the quantities are of same type . Like we cannot compare a length quantity with a temperature quantity.

Given that Tamika wants to predict the final temperature after some minutes of preheating her oven. She wrote the equation y = 45x + 67, where y represents the final temperature in degrees Fahrenheit.

y = 45x + 67

A system of equations that could be used to determine the number of hours the worker worked and the number of shirts the worker made is   28x + 2(4x) = 144

Let x be the number of working hours

She must pay the worker $28 per hour

So, Cost of labor for x hour = 28x

The worker created an average of 4 shirts per hour.

So, number of shirts produced in x hours = 4x

Cost of 1 shirt = 2

Cost of 4x shirts = 2 (4x)

Total expenses for labor and materials = 28x + 2(4x)

We are given that Aaliyah total expenses for labor and materials were $144

So,  28x + 2(4x) = 144
