4,7 is the one not equalivent to the others.

Step-by-step explanation:

All of the y values in the ratios have a gcf of 12. 7 Is not divisible by 12, let alone 9.

Hewo There! my name is Neko and I'll be helping you today! ;-)

Question:

Several ratios are graphed below. Which ratio is not equivalent to the others?

Answer:

The ratio of 4 to 7 is not equivalent to others.

Step-by-step explanation:

  • <em>Connect the points by a straight line.</em>

<em />

  • <em>Equivalent points lie on the straight line</em>

<em />

  • <em>The given graph is in the Attachment</em>

<em />

  • <em>The (4, 7) doesn't lie on the straight line when the other three points lie on the line.</em>

<em></em>

<u><em>Hence (4, 7) is not equivalent to (2, 3), (6, 9), and (8, 12) </em></u>

<u><em></em></u>

<u><em></em></u>

<em>I hope this helps you!</em>

<em>Have an Amazing Friday!</em>

Lelechka [254]

Answer:

(a) P(X=10) = 0.2070

(b) P(X\geq 10) = 0.3798

Step-by-step explanation:

Note that in this problem we have an initial population N = 50, of which 30 fulfill a certain characteristic "m" (belong to the second section). Then, from the population N, a sample of size n = 15 is selected and it is desired to know how many comply with the desired characteristic (second section).

So

Let X be the number of projects in the second section, then X is a discrete random variable that can be modeled by a hypergeometric distribution.

(a)

Therefore, to answer question (a) we use the following equation presented in the attached image:

Where:

N = 50\\m = 30\\n = 15\\X = 10

Then:

P (X = 10) = \frac{\frac{30!}{10!(30-10)!}\frac{20!}{5!(20-5)!}}{\frac{50!}{15!(50-15)!}}\\\\\\P(X=10) = 0.2070

(b)

For part (b) we have:

P(X\geq10) = 1-P(X

P(X\geq 10) = 1-0.6202 \\\\P(X\geq 10) = 0.3798

vagabundo [1.1K]

Answer:

It has no solution because, 14x cancels out -14x when you move the variables to the left and leaves the equation as 0 = -12, however we know that 0 does not equal -12 which means this solution is false; therefore this equation has no solution since 0 does not equal -12.

Step-by-step explanation:

5 - 4x - 7 - 10x = -8x - 4 - 6x - 10 (Given)

-2 - 14x = -14x - 14 (Combine like terms)

0 = -12 (Move variables(x) to the left and the constants to the right)

&lt;1 and &lt;2 form a linear pair. The measure of &lt;1 = (2x+8) and the measure of &lt;2 = (8x + 22). What is the measure of &
attashe74 [19]

Answer:

Step-by-step explanation: Since the given problem states that the two angles, angle 1 and angle 2 form a linear pair, this means that they form a 180° line, so that:

measure angle 1 + measure angle 2 = 180°

Since measure of angle 2 is six more than twice the measure of angle 1, therefore:

measure angle 2 = 2 (measure angle 1) + 6

hence, substituting this into the first equation:

measure angle 1 + 2 (measure angle 1) + 6 = 180

3 (measure angle 1) = 174

measure angle 1 = 58°

Therefore,

measure angle 2 = 2 (measure angle 1) + 6

measure angle 2 = 2 (58°) + 6

measure angle 2 = 122*
