Hi there! :)

Answer:

X = 30

Y = 97

Step-by-step explanation:

The lines on each side of the figure means that the side with 1 line is equal to the other side with 1 line and the side with 2 lines is equal to the other side with 2 lines.

Let's start by the sides with 1 line:

4x = 3x + 30

Now solve this equation by isolating "x":

4x = 3x + 30

Subtract 3x from each side of the equation: 4x - 3x = x

x = 30

Now that you know the value of "x", you can go ahead and find the value of "y" by replacing the "x" in the expression of the side with 2 lines and isolating the equation by isolating "y":

y = 7 + 3x

y = 7 + (3 × 30)

y = 7 + 90

y = 97

There you go! I really hope this helped, if there's anything just let me know! :)

All you need to do is plug in some x values and find the correspoding y value
when x=0, y=-3
when x=1, y=9
when x=2, y=21
when x=-1, y=-15

A 99% confidence interval for the difference between two proportions was estimated at 0.11, 0.39. Based on this, we can conclude

sladkih [1.3K]

Answer:

$\hat p_1 -\hat p_2 \pm z_{\alpha/2} SE$

And for this case the confidence interval is given by:

$0.11 \leq p_1 -p_2 \leq 0.39$

Since the confidenc einterval not contains the value 0 we can conclude that we have significant difference between the two population proportion of interest 1% of significance given. So then we can't conclude that the two proportions are equal

Step-by-step explanation:

Let p1 and p2 the population proportions of interest and let $\hat p_1$ and $\hat p_2$ the estimators for the proportions we know that the confidence interval for the difference of proportions is given by this formula:

$\hat p_1 -\hat p_2 \pm z_{\alpha/2} SE$

And for this case the confidence interval is given by:

$0.11 \leq p_1 -p_2 \leq 0.39$

Since the confidence interval not contains the value 0 we can conclude that we have significant difference between the two population proportion of interest 1% of significance given. So then we can't conclude that the two proportions are equal

The larger of the two numbers is 4 more than twice the smaller. The difference of the larger number and the smaller number is 6.

xxMikexx [17]

Answer:

2 and 8

Step-by-step explanation:

Larger number = y

Smaller number = x

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

y = 2x+4

y - x = 6 -> y= x+6

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

x + 6 = 2x + 4

2 = x

y = x+ 6

y = 2 + 6

y = 8

Hope this makes sense!!!!

A circle with a radius of 5 cm has an area of 78.54 cm2. What constant, rounded to the nearest hundredth, do you get when the ar

Naily [24]

Answer:

3.14

Step-by-step explanation:

Area of a corcle is sexpressed as';

A = πr²

π = A/r²

π = 78.54/5²

π = 78.54/25

π = 3.1416

When the area is divided by radius the required constant is 3.14
