let the consecutive odd integers be

x, x+ 1, x+ 2, x + 3, x + 4

Average = sum / total number

Average = -45

Total number = 5

-45 = x + x + 1 + x + 2 + x + 3 + x + 4 / 5

Introduce cross multiplication

-45 x 5 = x + x + 1 + x + 2 + x + 3 + x + 4

-225 = x + x + x + x + x + 1 + 3 + 4 + 5

-225 = 5x + 16

The trigonometry expression is cos Ф = 3√5/7 , sec Ф = 7/3√5, cosec Ф = 7/2, tan Ф = 2/3√5, cot Ф = 3√5/ 2

sin Ф = perpendicular(p) / hypotenuse(h)

         = 2/7

base(b) = √(h²-p²)

            =[tex]\sqrt{7^{2} - 2^{2} }[/tex]

            = √45

            = 3√5

cosФ = b/h

         = 3√5/7

sec Ф = h/b

          = 7/3√5

cosec Ф = h/ p

             = 7/2

tan Ф = p/b

          = 2/3√5

cot Ф = b/p

          =3√5/ 2

Therefore cos Ф = 3√5/7, sec Ф = 7/3√5, cosec Ф = 7/2, tan Ф = 2/3√5, cot Ф = 3√5/ 2.

Answer:

5.0 km.

Step-by-step explanation:

Answer: 4.25 Km

Step-by-step explanation:

First you're going to consider the first number given as the main one to start with. (1.5 km)

The question told you that the hiker first went north so you can consider north positive, then he walked back south 0.45 km.

So far your calculation should be 1.5 - 0.45 = 1.05

Then the hiker walks again north with a distance of 3.2 km

so now add that to your value (1.05) as 1.5 and 3.2 are going to the same direction and 0.45 is only opposing them

Final calculation: 1.05 + 3.2 = 4.25 (1.5 - 0.45 + 3.2)

Another way of explaination if you didn't get this one:

The two values 1.5 and 3.2 are mentioned to be in the same direction (north), while 0.45 is mentioned to be opposing them going south, so you can either consider it as
(+)1.5 + 3.2 - 0.45  (But this one would make more sense)

        Or

- 1.5 - 3.2 + 0.45

The inicial number of jobs is 63.1 thousand, and each year this number will decrease by 1.7 thousand.

So the change from 2008 to 2018, that is, 10 years, will be:

To find the change in percentage, we need to divide the change (-17) by the inicial amount of jobs (63.1), then we have that:

So the change in this period is -27%, therefore the answer is B.

Step 1: Name the equation

12y = 28x + 60 ....... equation 1

9y = 21x + 45 ........... equation 2

Step 2: Eliminate one of the variables (either x or y ) in the two equations

To do this,

(12y = 28x + 60) multiply by 9

=> 108y = 252x + 540 ........ equation 3

(9y = 21x + 45 ) multiply by 12

=> 108y =252x + 540....... equation 4

step 4

equate equations 3 and 4

252x + 540 = 252x + 540

step 5 :solve the equation

252 x -252x = 540

0 = 0

Hence, the Equations has no solution

Answer:

6 i think

Step-by-step explanation:

if you count the top and bottom one, thats 2, the two sides, and the front and back. add 2+2+2 which is 6.

When a line is steeper than other one it means it has a greater slope. In this case the slope represents the speed of Melinda and Paul. As shown in the picture, the line that represents Paul's movement has a greater slope than the one that represents Melinda's, it means Paul ran at a faster constant speed than Melinda.

If Melinda ran at a constant velocity of 5mph and Paul ran faster than her, an equation that could represent the relationship between Paul's distance an his time has to have a greater slope than 5, which is 7.

Answer

Regular pay = $388

Overtime pay = $87.3

Gross pay = $388 + $87.3

= $475.3

Explanation

During the first week of January, Patricia Morgan worked 46 hours at a rate of $9.70 per hour for regular hours.

For overtime, the pay is 1.5 times the normal rate. That is, 1.5 × $9.70 = $14.55

So, working for 46 hours, that is, 40 hours regular pay rate, and 6 hours overtime pay rate.

Regular pay = 40 × $9.70 = $388

Overtime pay = 6 × $14.55 = $87.3

Gross pay = Regular pay + Overtime pay

= $388 + $87.3

= $475.3

Options E and F are the correct options

Here, we need to get the equation of the line that passes through the two points given

Mathematically, the equation of a line can be generally expressed as ;

y = mx + c

where m is the slope of the line and c is the y-intercept of the lien ( where it crosses the y-axis)

To get the slope m , we are goint to use the formula below;

Substituting these values into the slope equation , we have

m = (-1-(6))/(-1-(-5)) = -7/4

The equation is now in the form;

y = -7x/4 + c

what is left is to get the y-intercept

We can get the value of the y-intercept by substituting for x and y using any of the points

Let us use the second point

Here, x = -1 and y = -1

Thus;

-1 = -7(-1)/4 + c

-1 = 7/4 + c

c = -1-7/4 = -11/4

So the complete equation of the line is;

y = -7x/4 - 11/4

To properly answer the questions, we need the forms in the options that looks like or can be manipulated arithmetically to look like what we have as our answer

We proceed with each of the options one after the other to see if they can be written in the form of our answer

Option A

y - 5 = -7/4 ( x + 6)

Opening the bracket and evaluating;

y - 5 = -7x/4 - 42/4

y = -7x/4 -42/4 + 5

y = -7x/4 -22/4

we can see this is not a correct option

Option B

y - 6 = -4/7 (x + 5)

Multiply through by 7

7y - 42 = -4x - 20

7y = -4x - 20 + 42

7y = -4x + 22

divide through by 7

y = -4x/7 + 22/7

We can see this is incorrect also

Option C

y - 1 = -4/7(x-1)

Multiply through by 7

7y - 7 = -4x + 4

7y = -4x + 4 + 7

7y = -4x + 11

divide through by 7

y = -4x/7 + 11/7

This is incorrect too

Option D

y + 1 = -4/7 ( x + 1)

Multiply through by 7

7y + 7 = -4x - 4

7y = -4x -4 -7

7y = -4x - 11

y = -4x/7 - 11/7

This is incorrect also

Option E

y - 6 = -7/4 (x + 5)

Multiply through by 4

4y - 24 = -7x - 35

4y = -7x - 35 + 24

4y = -7x -11

y = -7x/4 - 11/4

This is a correct option

Option F

y + 1 = -7/4 ( x + 1)

Multiply through by 4

4y + 4 = -7x - 7

4y = -7x - 7-4

4y = -7x - 11

y = -7x/4 - 11/4

This is a correct option too

The 78th Percentile is 55.402

What is Percentile?

A Percentile (or centile) is a statistic measure that indicates the value below which a given percentage of observations in a group fall. The 20th percentile, for example, is the value (or score) below which 20% of the observations can be found.

The terms Percentile and Percentile rank are frequently used in the reporting of norm-referenced test scores. For example, a score in the 86th percentile, where 86 is the percentile rank, corresponds to a value below which 86% of the observations can be found. In contrast, a score in the 86th percentile indicates that it is at or below the value at which 86% of the observations can be found.

We know that,

μ = 50,

and σ = 7,

First, we need to find the z-score associated to this percentile.

We need to find the value [tex]Z_{p}[/tex] that solves the equation below.

[tex]Pr(Z < Z_{p}) = 0.78[/tex]

The value of [tex]Z_{p}[/tex] that solves the equation above cannot be made directly, it is solved either by looking at a standard normal distribution table or by approximation.

Based on this, we find that that the solution is [tex]Z_{p}[/tex] 0.772, because from the normal table we see that

Pr(Z<0.772)=0.78

Therefore, the percentile we are looking for is computed using the following formula:

[tex]P_{78}[/tex] = μ+ [tex]Z_{p}[/tex] × σ

= 50+0.772×7

= 55.405

Therefore, it is concluded that the corresponding 78-th percentile is found to be [tex]P_{78}[/tex] is 55.405.
