Answer:
d = 3/4
Step-by-step explanation:
divide 0.6 both sides
d+3 = 5d
4d = 3
d = 3/4
Means can be translated to average
average= total number/number of objects or numbers
so the answer is 393, 399, 402,402,407, 410, 424, 425, 428 all added together then divided by 9
if we use a calculator to add them up we get 3690
then divide by 9
3690/9=410
410 is the mean
Answer:

Step-by-step explanation:
We know that we have a 9 foot long ladder resting upon a wall, with an unknown height, but the ladder is 4.5 feet away from the wall.
This can be represented as a triangle, where x is the unknown side.

We can use The Pythagorean Theorem to find the value of x. The theorem states that
, where a and b are the lengths of the legs and c is the length of the hypotenuse.
However, we already know the hypotenuse and one leg. Therefore we can substitute inside the equation to find the missing value.

Hope this helped!

Answer:
P(number greater than 3) = 
Step-by-step explanation:
The Probability of getting a number greater than 3 means the possibility of getting 4 or 5 or 6
That is
P(number greater than 3) = P(getting 4) + P(getting 5) + P(getting 6)
On substituting the values from the table ,
we get
P(number greater than 3) = 
P(number greater than 3) = 
Thus if the number cube is tossed once, P(number greater than 3) is
