I really need help please answer would help a lot

Answer:

y = 4x -19

Step-by-step explanation:

y = 4x + b

first we add the point to the equation and then we solve for b

-3 = 4 ( 4 ) + b

-3 = 16 + b

     -16

-19 = b

Before you read this!! To me, it looks like 8 is the entire length of lineJL, but it may only be the length of lineJM. I've written the steps for lineJL=8 NOT lineJM=8. If this is not the case and 8 is only the length of lineJM let me know so I can fix my answer!

Step-by-step explanation:

The area of a triangle is A=1/2(b)(h)

B=base

H=height

Your height is found in the line in the middle of the triangle, for you it is 6.

The base is the long bottom line on the triangle (lineJL), for you it is 8.

So let's put it in.

A=1/2(8)(6)

A=24sq units (C)

Answer:

AB=15

Step-by-step explanation:

Since DM =MA and CN=NB, then DC || MN || AB

29-22=7

22-7=15

AB=15

Answer:

area of ABC=1/2 b×h=1/2×20×6=30m²

Answer:

60 m^2

Step-by-step explanation:

( Base * Hight / 2 = Area)

20 * 6 = 120

120 / 2 = 60

Step-by-step explanation:

step 1. I assume i is imaginary

step 2. i^2 = -1, i^3 = -i, i^4 = 1, i^5 = I. . . . and so on

step 3. i - 1 - i + 1 + i - 1 - i + 1 + i - 1

step 4. the result is i - 1.

Answer:

The calculated z = 2.85 falls in the critical region z > 1.96 so we accept the null hypothesis that there is no difference between the population proportions for the two years.

Step-by-step explanation:

Let p1 be the sample of 1000 adults chosen in 2012 and

p2 be the sample of 1100 adults chosen in 2010

Part a:

The hypothesis that can be used to test for a significant difference between the population proportions for the two years is:

H0: p1-p2= 0           against the claim      Ha: p1-p2≠0

Part b:

The sample proportion indicating that their financial security was more that fair in 2012 is

p1^= 410/1000= 0.41

In 2010 is:

p2^= 385/1100= 0.35

Part c:

p^c= 410+385/1000+1100= 0.3785

q^c= 1-p^c= 1-0.3785= 0.6124

The critical region is z > ±1.96

The test statistic is

z= p1^- p2^ / sqrt ( p^cq^c( 1/n1+ 1/n2)

z= 0.41-0.35 /sqrt( 0.3785*0.6124(1/1000 +1/1100)

z=  0.06 / 0.021036

z= 2.85

Conclusion

The calculated z = 2.85 falls in the critical region z > 1.96 so we accept the null hypothesis that there is no difference between the population proportions for the two years.

P- value :  0.00466

The result is significant( accept the null hypothesis) for  value less than 0.05

Part d:

                                                     2012                         2010

Sample                                       1000                           1100

Proportions                               0.41                             0.35

Standard Error               √0.41( 0.59)/1000        √0.35( 0.65)/1100

                                               = 0.0155                0.01438

Standard Error for the difference = √0.0155² + 0.01438² =0.0211

p1-p2 ± z* standard error for the difference

0.41-0.35 ± 1.96 *( 0.0211)

0.06 ± 0.041356

-0.018644,   0.101356

The 95 % confidence interval estimate is (-0.018644,   0.10135

Answer:

$24.

Step-by-step explanation:

Given that I deposited $ 200 in an account that earns 4% simple interest annually, to determine how much interest did I earn in 3 years, the following calculation must be performed:

((200 x 4/100) x 3) = X

((800/100) x 3) = X

(8 x 3) = X

24 = X

Thus, after 3 years of investment I will have earned $ 24 in interest.

Step-by-step explanation:

This one is just simple division, so you divide the goal number which is -5400 by -60 but in this situation you can just make them positives.

Given:

The figure of a regular polygon.

To find:

The area of the regular polygon.

Solution:

From the given figure it is clear that the regular polygon has 4 vertices. It means, it is a square.

Distance between the center and the vertex is 7 yd. So, the diagonal of the square is

[tex]d=7+7[/tex]

[tex]d=14[/tex] yd

We know that, area of a square is

[tex]A=\dfrac{1}{2}d^2[/tex]

Putting d=14 in the above formula, we get

[tex]A=\dfrac{1}{2}(14)^2[/tex]

[tex]A=\dfrac{1}{2}(196)[/tex]

[tex]A=98[/tex]

Therefore, the area of the regular polygon is 98 sq. yd.

50 pounds to be exact

Step-by-step explanation: To shift the graphs up and down on the coordinate system, you need to manipulate or change the y-intercepts.

The y-intercept is just the constant term in the equation.

As long as the slopes remain the same, the graphs can be

translated up or down by changing the constant value.

Take a look at these lines graphed below.

Notice that y = x + 11 is the same as y = x + 4 but

y = x + 11 is translated 7 units down to get y = x + 4.

Definition of  an equilateral triangle: A triangle with the exact same sides and angles, which is 60°

5 more than twice a number:

Let the number be x:

2x + 5

Since it is an equilateral triangle, multiply that by 3:

3(2x +5) = 6x + 15

The perimeter is (6x + 15) inches.

Given:

The two numbers are 19.8 and 5.

To find:

The estimated product of given numbers by rounding each factor to nearest whole number.

Solution:

Two number are 19.8 and 5.

On rounding the given numbers to the nearest whole number, we get 20 and 5.

Now, the estimated product is

[tex]20\times 5=100[/tex]

Therefore, the estimated product of given numbers is 100.
