What is the value of b^2 0 4ac for the following equation? 2x^2 0 2x 0 1 = 0 04 0 12

tigry1 [53]

2x^2 - 2x - 1 = 0 a = 2, b = -2, c = -1 b^2 - 4ac = (-2)^2 - 4(2)(-1) = 4 + 8 = 12

Four diners have ordered a platter of desserts. The platter holds 8 chocolate chip cookies and 4 slices of chocolate cheesecake.

Furkat [3]

Answer:

$P(Y>1 \cap Y$

And we can find this probability like this:

$P(Y>1 \cap Y$

And we can replace the values and we got:

$P(Y>1 \cap Y$

Step-by-step explanation:

For this case we define the random variable Y as: the number of slices of cheesecake left on the platter after the first serving. And we have the following distribution for Y:

Y | 0 1 2 3 4

P(Y) | 0.005 0.114 0.429 0.381 0.071

And we want to find the following probability:

$P(Y>1 \cap Y$

And we can find this probability like this:

$P(Y>1 \cap Y$

And we can replace the values and we got:

$P(Y>1 \cap Y$

use the graph to determine the domain and range of the relation and state whether the relation is a function

Alex

Answer:

the domain is {0, 1, 2, 3, 4... to positive infinity}

The range is {-1, -3, 0, -4 and so on}

this is not a function

Step-by-step explanation:

domain is a set of all x values, so just write the x values based on the graph

range is a set of all y values, so just write y values based on the graph

not function because it doesnt satisfy with the vertical line test.

i hop it help u
