Answer:

x=132°

Step-by-step explanation:

All four angles should add up to 360°

65°+86°+77°+x=360°

x=132°

Answer:

I got 132⁰ ans by adding all sides of no.

The equation of the line that is perpendicular to y = 2x + 4 and passes through the point (4, 6) is y = (-1/2)x + 8.

The given equation is y = 2x + 4, which is in slope-intercept form,

y = mx + b, where m is the slope of the line.

The slope of this line is 2.

A line that is perpendicular to this line will have a slope that is the negative reciprocal of 2, which is -1/2.

Using the point-slope form of the equation of a line,

which is y - y(1) = m(x - x(1)), where (x(1), y(1)) is a point on the line, we can find the equation of the line that passes through the point (4, 6) and has a slope of -1/2:

So,

y - 6 = (-1/2)(x - 4)

y - 6 = (-1/2)x + 2

y = (-1/2)x + 8

Therefore,

The equation of the line that is perpendicular to y = 2x + 4 and passes through the point (4, 6) is y = (-1/2)x + 8.

Answer:

Length of arc between two cars = 7 feet (Approx.)

Step-by-step explanation:

Given:

Radius of carinal wheel = 18 feet

Number of car equal distance = 16

Find:

Length of arc between two cars

Computation:

Angle between two cars = 360 / 16

Angle between two cars = 22.5°

Length of arc = [θ/360][2πr]

Length of arc between two cars = [22.5/360][(2)(3.14)(18)]

Length of arc between two cars = [0.0625][(6.28)(18)]

Length of arc between two cars = [0.0625][113.04]

Length of arc between two cars = 7.0625

Length of arc between two cars = 7 feet (Approx.)

Answer:

30

Step-by-step explanation:

Use pythagorean Theorem to find the hypotenuse

a² + b² = c²

5² + 12² = c²

25 + 144 = c²

169 = c²

Take the square root of both sides

c = 13

Perimeter = 5 + 12 + 13

p = 30

Answer: 50%

Step-by-step explanation:

From the question given, we are informed that a fish tank has sprung a leak at the bases of the tank and that 5% of the water is lost every minute

Based on the information given, the amount of water that is lost from the tank after ten minutes will be:

= 5% × 10

= 0.05 × 10

= 0.5

= 50%

This means that after 10minutes, 50% of the water will be lost.

Step-by-step explanation:

If we are dealing with a standard deck of cards with 52 cards, there is only one queen of hearts.

p(not queen of hearts) = 51/52

Answer:

51/52

Step-by-step explanation:

There is only one queen of hearts in a standard deck of cards. Assuming you are picking it out of a standard deck of cards, you have a 51/52 chance of not getting it (since there are 52 cards in a deck).

Problem 1

Answers:

Mean = 51.68

Median = 51

There are 100 values

IQR = 54

---------------------

Explanation:

The values are found in the table. The IQR (interquartile range) is the difference of Q3 and Q1.

IQR = Q3 - Q1 = 77 - 23 = 54

===========================================================

Problem 2

Answer: C) Mean is greater than the median

---------------------

Explanation:

The main clump of values is pretty much between 80 and 110. The other values can be considered in the right tail, which is pulled out more compared to the left tail. We consider this a right skewed distribution, and that indicates the mean is larger than the median. The tails always pull on the mean toward it. A very long way to confirm this answer is to manually enter the values into a calculator and compute the mean and median, but that would be tedious busy work in my opinion.

===========================================================

Problem 3

Answers: A) Mean and median are the same value

---------------------

Explanation:

This data set is uniform and symmetric about the center, so the mean = median.

===========================================================

Problem 4

Answer: Choice A)

=MIN(A1:A10)

---------------------

Explanation:

We use the MIN function, and we select everything from cell A1 to A10. The colon tells us to select everything between those endpoints and including those endpoints. If we wrote =MIN(A1,A10), then we would only select the two endpoints only and nothing in between, which isn't what we want.

===========================================================

Problem 5

Answer: Choice D

=QUARTILE(A1:A10, 3)

---------------------

Explanation:

The QUARTILE function is what we'll use. It has two inputs. The first is the data itself, which is the values from A1 to A10. The second input entry is the quartile we want, which is the third quartile. So we'll use "3" in the second slot as choice D indicates.

As far as I know, excel doesn't have an "upperquartile" function and neither does any other spreadsheet program (I could be mistaken however). Choice B describes finding the first quartile on the items from A1 to A10.  

Choice C is nonsense because cell B1 isn't shown, that item isn't in the proper column. If you want to select another column, you need to tack that onto the end rather at the beginning. Also, and this is very important, the selection input must be rectangular. So if you wanted to include column B, you would have to start at A1 and end at B10. The input would be A1:B10. Saying A1:B1 would produce an error.

Answer:

Problem 1)

[tex]-11<x<-4[/tex]

Sample value is -6.

Problem 2:

[tex]3<y<9[/tex]

Sample value is 6.

Problem 3:

[tex]5<z<6[/tex]

Sample value is 5.5.

Step-by-step explanation:

We can write inequalities to represent each situation.

Problem 1)

(11 + x) is positive and (4 + x) is negative. In other words:

[tex]11+x>0\text{ and } 4+x<0[/tex]

Solving for x yields:

[tex]x>-11\text{ and } x<-4[/tex]

Combining them:

[tex]-11<x<-4[/tex]

Any values that satisfy this inequality will work.

An example will be -6.

Problem 2)

(-3 + y) is positive and (-9 + y) is negative. Hence:

[tex]-3+y>0\text{ and } -9+y<0[/tex]

Solving for y yields:

[tex]y>3\text{ and } y<9[/tex]

So:

[tex]3<y<9[/tex]

A sample value will be 6.

Problem 3)

(-5 + z) is positive and (-6 + z) is negative. Hence:

[tex]-5+z>0\text{ and } -6+z<0[/tex]

Solving for z yields:

[tex]z>5\text{ and } z<6[/tex]

So:

[tex]5<z<6[/tex]

A sample value will be 5.5.

Answer:

1) you can choose: -5, -6, -7, -8, -9, or -10

Step-by-step explanation:

If you subtract 11 + -5 through -10 you have a positive number. If you subtract 4 + -5 through -10 you have a negative number.

Answer:

Step-by-step explanation:

Statement best interprets the coefficient and base of this equation  Copper production increased by a factor of 523,430x1.193 pounds per year during that period.

We have given that,

The equation c = 523, 430(1.193)

It models United States copper production in pounds from 1987 to 1992.

The pound or pound-mass is a unit of mass used in British imperial and the United States customary systems of measurement.

from the given, we have the slope is  430.

Therefore the correct option is,

Copper production increased by a factor of 523,430x1.193 pounds per year during that period.

Answer:

$14.70

Step-by-step explanation:

Find the 30% decrease:

21*0.3 = 6.3

Find new price:

21-6.3 = 14.7

Answer:

$14.7

Step-by-step explanation:

First, we need to convert the percentage to a decimal. 30% = .30

Now we multiply the price times the decimal, 21 x .30 = 6.3

We subtract this amount from the previous cost. 21 - 6.3= $14.7
