Answer:

1/45

Step-by-step explanation:

make a probability of how many blues are in the bag

2/10.

simplify

1/5

Now that a marble is tooken away. there will be only one blue marble and 9 total marbles. make another probability.

1/9

now multiply the two probabilities.

Click on the graph to choose the correct answer to the equation. 3x - y ≥ 5 hurry

mr_godi [17]

For this case we have:

To begin we must graph $3x-y = 5$ , for this:

We do $x = 0$ , then:

$3 (0) -y = 5\\-y = 5\\y = -5$

So, we have the point $(x_ {1}, y_ {1}) = (0, -5)$

We do $y = 0$ , then:

$3x-0 = 5\\3x = 5$

$x = \frac {5} {3}$

So, we have the point $(x_ {2}, y_ {2}) = (\frac {5} {3}, 0)$

We place both points in a coordinate plane and graph the line. Now, we must find the shaded region that identifies the inequality $3x-y\geq 5$

We must replace any point located to the left or to the right of the line. If the inequality is met, then the shaded region will be on the respective side.

We substitute the point $(x_ {3}, y_ {3}) = (5,0)$

$3 (5) -0\geq5 \\15\geq5$

The inequality is met, then the shaded region is to the right of the line.

Based on the z-statistic of –2.5 for the sample data, should the null hypothesis be rejected? Yes, because the z-statistic lies

ivann1987 [24]

Answer:

No, because z-statistics lies within the critical region.

Step-by-step explanation:

The z value is calculated to determine whether the null hypothesis should be accepted or rejected. The null hypothesis is rejected when the z-value lies outside the critical region. The critical region is determined by the sample data.
