Answer:

[4, positive infinity)

Step-by-step explanation:

since there is a closed circle on 4, we include 4 in the continuous interval, and we assume that the arrow represents continuity after the graph ends, so the interval of continuity is from 4 to positive infinity.

What is the volume of the cone below:<br> 5 cm<br> 12 cm<br> 13 cm

maksim [4K]

Answer:

<em>780cm cubed</em>

Step-by-step explanation:

<em>if we want to find the volume we would do length x width x height</em>
<em>which would be 5 x 12 x 13</em>
<em>so we would do 5 x 12 which is 60 </em>
<em>then we would do 60 x 13 which equals 780</em>
<em>So the answer is 780</em>
<em>Since this is volume it would be 780cm cubed</em>

1. Points A and B are to be mapped onto a number line according to two equations. The solution to the equation 2/3 A= -24 is the

OleMash [197]

<span>The solution to the equation 2/3 A= -24 is the coordinate of point A.

2/3 A = -24
A = -24 / 2/3
A = -24 * 3/2
A = -72/2
A = -36

The solution to the equation 20=-b/0.5 is the coordinate of point B

20 = -b/0.5
20 * 0.5 = -b
10 = -b
10/-1 = -b/-1
-10 = b

A = -36 and B = -10

The distance between the two letters is 26 units. </span>

Q5: The probability that event A occurs is 5/7 and the probability that event B occurs is 2/3 . If A and B are independent event

bekas [8.4K]

Answer:

$P(A \cap B)$

And we can use the following formula:

$P(A \cap B)= P(A)* P(B)$

And replacing the info we got:

$P(A \cap B) = \frac{5}{7} \frac{2}{3}= \frac{10}{21}=0.476$

Step-by-step explanation:

We define two events for this case A and B. And we know the probability for each individual event given by the problem:

$p(A) = \frac{5}{7}$

$p(B) = \frac{2}{3}$

And we want to find the probability that A and B both occurs if A and B are independent events, who menas the following conditions:

$P(A|B) = P(A)$

$P(B|A) = P(B)$

And for this special case we want to find this probability:

$P(A \cap B)$

And we can use the following formula:

$P(A \cap B)= P(A)* P(B)$

And replacing the info we got:

$P(A \cap B) = \frac{5}{7} \frac{2}{3}= \frac{10}{21}=0.476$
