What is the equation of the line that is parallel to the line represented in the table and goes through the point (-10, -2)?

Answers

Answer:

y = -3/2x - 17

Step-by-step explanation:

First you need to find the slope, since the lines are parallel the slopes would be the same as points of the other line on the table. When finding the slope you get -3/2, when you have the slope you need to find the y-intercept or in other words in y=mx+b, the "b" in the equation. In order to find the y-intercept you have to plug in the values of the point (-10,-2) so then the equation would look like -2 = -3/2(-10) + b. Then you would solve for b. Then when you put the components together you get y = -3/2x - 17.

Answers

Answer:

Step-by-step explanation:

Since ΔABC ≅ ΔXYZ,

By the property that says that "corresponding parts of the congruent triangles are congruent"

Corresponding angles (Including right angle) will be equal.

m∠A = m∠X = 180° - (90° + 37°) = 53°

m∠B = m∠Y = 90°

m∠C = m∠Z = 37°

Corresponding sides of the triangles will be equal.

AB ≅ XY = 3 units

BC ≅ YZ = 4 units

AC ≅ XZ = 5 units

From the sum of 3x +4y -3xy and 5x +3y -2xy subtract the sum of 2x +y – 3xy and 10x -9y -8xy.

Answers

Answer:

-4x + 16y + 3xy

Step-by-step explanation:

The sum of 3x + 4y - 3xy and 5x + 3y - 2xy is 8x + 7y - 5xy.

The sum of 2x + y - 3xy and 10x - 9y - 8xy is 12x - 8y - 11xy.

Subtract the sum of the second pair from the first pair by changing the sign of the subtrahend. The result is -4x + 16y + 3xy

The LCM of two numbers in 2310 and their HCF.
is 30 . If one number is 210, find the other number.​

Answers

Answer:

The other number is 330

Step-by-step explanation:

The computation of the other number is shown below:

As we know that

HCF × LCM = Product of Two Numbers

So,

30 × 2310 = 210 × other number

Now

The other number is

= (30 ×  2310) ÷ 210

= 330

hence, the other number is 330 and the same is to be considered

Answers

Complete Question

An analysis of several polls suggests that 60% of all Florida voters plan to vote for Anderson. A poll of 250 randomly selected Florida voters shows that 144 plan to vote for Anderson.

Required:

a. What is the probability of this result (i.e. 144 voters or less out of 250) happening by chance, assuming the aggregate poll model proportion of 60% is correct?

b. Does your result from part I indicate that the number of voters who plan to vote for Anderson has decreased? In other words, is this outcome unusual?(Recall that an unusual  event has a probability of 0.05 or less of occurring )

Answer:

a

[tex]P(p  <  \^p) =   0.2206[/tex]

b

It is not an unusual event

Step-by-step explanation:

From the question we are told that

    The population proportion is  p =  0.60

   The sample size is  n =  250

    The number that plans to vote for Anderson is  k =  144

Generally the mean of the sampling distribution is  

        [tex]\mu _{x} =  p =  0.60[/tex]

Generally the standard deviation is  

      [tex]\sigma  =  \sqrt{ \frac{p(1 - p )}{n} }[/tex]

=>    [tex]\sigma  =  \sqrt{ \frac{0.60(1 - 0.60 )}{250} }[/tex]

=>    [tex]\sigma  =   0.0310[/tex]

Generally the sample proportion is mathematically represented as  

         [tex]\^{p} =  \frac{k}{n}[/tex]

=>       [tex]\^{p} =  \frac{144}{250}[/tex]

=>     [tex]\^{p} = 0.576 [/tex]

Gnerally the probability of this result (i.e. 144 voters or less out of 250) happening by chance, assuming the aggregate poll model proportion of 60% is correct is mathematically represented as

  [tex]P(p  <  \^p) =  P(\frac{ p - \mu_{x}}{ \sigma }  <  \frac{ \^ p - \mu_{x}}{ \sigma } )[/tex]

=>     [tex]P(p  <  \^p) =  P(Z <  \frac{ 0.576 - 0,60}{ 0.0310} )[/tex]

=>      [tex]P(p  <  \^p) =  P(Z <  -0.77 )[/tex]

From the z-table  the probability of (Z <  -0.77)  is  

     [tex]P(Z <  -0.77 )  =  0.2206[/tex]

So

    [tex]P(p  <  \^p) =   0.2206[/tex]

Since

  [tex]0.2206 > 0.05[/tex] it implies that it is not an unusual  event

Answer:

11. B 12. C 13. B

Step-by-step explanation:

11. Since segment MR bisects segment QO, side QP and side PO are equal. In the problem it states that angle MQP is congruent to angle ROP. The the angles QPM and OPR are vertical, so they are equal. That is enough evidence to conclude the answer.

12. ADC is bisected by BD, so that bisects AC too, which makes both sides equal. BD is perpendicular to AC, making right angles on both sides. The curves at angle A and angle C show that they are congruent. That should be enough evidence to show that it is congruent by ASA.

13. Triangle cannot be congruent by having the same angles, only similar since the lengths can be different. Congruent triangle means that the sides and angles are the same.

Which ordered pair is a solution of the equation y = –54x – 2?

A. (−8, 8)
B. (8, −8)
C. (−8, −12)
D. (1, −154)

Answers

Answer:

A

Step-by-step explanation:

(-8,8) is the solution of the equation y=-5/4x-2.

What is an equation?

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

The given equation is,

y=-5/4x-2,

To find solution for the given equation, solve with the help of options,

(A) (-8,8)

8=-5/4(-8)-2

8 = 10-2

8 = 8

(-8,8) is the solution of the equation

(B) (8,-8)

-8=-5/4(8)-2

-8 = -10-2

-8 = -12

(8,-8) can not be the solution of the equation.

(C) (-8,-12)

-12 = -5/4(-8)-2

-12 = 8

(-8,-12) can not be the solution of the equation.

(D) (1, −15/4)

-15/4 = -5/4(1)-2

-15/4 = -13/4

(1,--15/4) can not be the solution of the equation.

(-8,8) is the solution of the equation.

In the diagram below, the radii of the two concentric circles are 3 centimeters and 7 centimeters, respectively.
What is the area of the shaded region?

Answers

Answer:

125.6 cm²

Step-by-step explanation:

Area of the shaded region = area of larger circle - area of the smaller circle

Area of the smaller circle = πr²

π = 3.14, r = 3 cm

Area of smaller circle = 3.14*3² = 3.14*9 = 28.26 cm²

Area of larger circle = πr²

π = 3.14, r = 7

Area of larger circle = 3.14*7² = 3.14*49 = 153.86 cm²

Area of the shaded region = 153.86 - 28.26 = 125.6 cm²

Answers

Answer:

21.2d + 12.4f

Step-by-step explanation:

Given that:

Width of rectangle = (5.5d+9.7f) centimeters

Length of rectangle = (5.1d-3.5f) centimeters

Perimeter of a rectangle : 2 (length + Width)

2 [(5.1d-3.5f) + (5.5d+9.7f)]

2[5.1d - 3.5f + 5.5d + 9.7f]

2[10.6d + 6.2f]

= 21.2d + 12.4f

Hence, the perimeter is :

I Need to show the equations please, and show my work

Answers

Answer:

15

Step-by-step explanation:

since both equations are set with a right angle, the equation must be equal to 90 degrees. So you set the equation as

13+x+4x+2=90

add the x variables together and the constants separately

15+5x=90

then subtract 15 from both sides.

15+5x=90

-15      -15

5x=75

then divide 5 from both sides.

75/5= 15

so x is 15 :).

Answer:

It shows a 90° angle split into 2 separate angles so,

[tex]13 + x + 4x + 2 = 90\\\\5x + 15 = 90\\\\5x = 75\\\\x = 15[/tex]

Basically, the total angle measure of the given angles [90°, (13 + x)°, and (4x + 2°) equals 180°. Take away 90 from 180 and you get 90, then solve for x using what's left: 13 + x + 4x + 2 = 90. You get x = 15.

Since 12 is closer to 10 than 20, the nearest ten is 10, which is the answer.

Step-by-step explanation:

This is the answer because:

1) We always have to look at the rounding digit (this digit is located right next to the tens digit in this problem).

2) Since the ones digit is smaller than 5, it has to round down to 10. If the digit was 5 or greater, than it would be 20.
