-4 is greater than -7 because bigger negative numbers are less than smaller negative numbers
For example -50 would be less than -25

A pair of dice is rolled, and the sum of the numbers is either 7 or 11. What is the probability of this event?

AfilCa [17]

Answer: $\dfrac{2}{9}$

Step-by-step explanation:

Let A be the event that the sum is 7 and and B be the event that the sum is 11 .

When two pair of dices rolled the total number of outcomes = $n(S)=6\times6=36$

The sample space of event A ={(1,6), (6,1), (5,2), (2,5), (4,3), (3,4)}

Thus n(A)= 6

The sample space of event B = {(5,6), (6,5)}

n(B)=2

Since , both the events are independent , then the required probability is given by :-

$P(A\cup B)=P(A)+P(B)\\\\=\dfrac{n(A)}{n(S)}+\dfrac{n(B)}{n(S)}=\dfrac{6}{36}+\dfrac{2}{36}=\dfrac{8}{36}=\dfrac{2}{9}$

Hence, the required probability = $\dfrac{2}{9}$

A pyramid has a base with a demension 5 inches by 7 inches .The height of the pyramid is unknown .If the volume of the pyramid i

Ulleksa [173]

Answer:

9 inches

Step-by-step explanation:

The volume of a pyramid is given as:

$V = \frac{l* w*h}{3}$

where l = length of base of pyramid

w = width of base of pyramid

h = height of pyramid

The volume of the cylinder is already known ( $105 in^3$ ) and the other two dimensions are known as 5 in and 7 in.

From the formula of the volume of the pyramid, the height of the pyramid is given as:

$h = \frac{3V}{l*h}$

Hence, the height of the pyramid is:

$h = \frac{3 * 105}{5 * 7}\\ \\h = \frac{315}{35} = 9in$

The pyramid's height is 9 inches.
