The sum of three different two-digit prime numbers is 79. the largest of the numbers is 43. the difference of the other two is 1
Zielflug [23.3K]
Let the number be x,y and 43
y-x=10
thus
y=10+x
the sum off the numbers will be:
x+y+43=79
plugging the values we get:
x+(10+x)+43=79
solving for x we get:
2x+53=79
2x=79-53
2x=26
x=26/2=13
hence:
y=10+13=23
thus the numbers are 13,23 and 43
the product of the number will be:
13×23×43
=12,857

Answer: 12,857

HELP!!<br> Which table is a probability distribution table?
fomenos

Answer:

Table 1 is the only table which represents PROBABILITY DISTRIBUTION table.

Step-by-step explanation:

In any given probability distribution:

1) The probability of each event should be strictly POSITIVE.

2) Sum of all events in a a distribution should be 1.

Now, here

A) All of the values of probability (0.11, 0..5, 0.49,0.35)  are positive.

Also, 0.11 +  0.5 +  0.49 + 0.35  = 1

So, the given table is a PROBABILITY DISTRIBUTION.

B)The table is NOT a PROBABILITY DISTRIBUTION as here

P(Blue) =  -1, which is negative.

C)The table is NOT a PROBABILITY DISTRIBUTION as here

P(Green) =  -0.49, which is negative.

D)The table is NOT a PROBABILITY DISTRIBUTION as here

P(Purple) =  -0.1, which is negative.

Hence, table 1 is the only table which represents  PROBABILITY DISTRIBUTION table.

Determine the number of possible triangles, ABC, that can be formed given A = 150°, a = 7, and b = 4.
GREYUIT [131]
1.

When  you have the length of two sides and the angle between them, the triangle is totally determined. This is, there is only one segment that can complete the triangle: its length and position is totally fixed.
