The line is rising up to the left and it starts at -2,-2

If you were to continue the line to cross the y a is it would cross at (0,-3)

Find the slope

Slope = (-2 - -1) / (—2 - -4) = -1/2

It would be y= -1/2x-3 when x<-2

2(-6x-4)+3 = 3(3x-3)+4
iren2701 [21]

Answer:

x = 0

Step-by-step explanation:

For this problem, we will simply solve the equation by isolating the variable x, to find the value of x.

2(-6x - 4) + 3 = 3(3x - 3) + 4

2*(-6x) + 2*(-4) + 3 = 3*(3x) + 3*(-3) + 4

-12x + -8 + 3 = 9x + -9 + 4

-12x + -5 = 9x + -5

12x + -12x + -5 = 12x + 9x + -5

-5 = 21x + -5

5 + -5 = 21x + -5 + 5

0 = 21x

0 = x

Hence, in this equation, the value of x is 0.

Cheers.

For a one-sample test for a population proportion p and sample size n, why is it necessary that np0 and n(1−p0) are both at leas
tino4ka555 [31]

Using the Central Limit Theorem, it is found that these conditions are required to avoid the high variability associated with small samples.

<h3>What does the Central Limit Theorem states?</h3>

It states that for a <u>proportion p in a sample of size n</u>, the sampling distribution of sample proportion is approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1 - p)}{n}}, as long as np \geq 10 and n(1 - p) \geq 10.

From the equation of the standard error, we could see that if one of the conditions is not respected, the standard error would be very high, indicating a low accuracy of the estimate, hence it is found that these conditions are required to avoid the high variability associated with small samples.

Urgent please help..
zvonat [6]

Answer:

x = 12

Step-by-step explanation:

Here, we want to find the value of x

To do this, we use one of the circle tangent relationships

we have this as:

8^2= 4(4 +x)

8^2 = 16 + 4x

64 = 16 + 4x

64-16 = 4x

4x = 48

x = 48/4

x = 12
