Answer:
this can help you all you have to do to figure it out your self is look up algabra calculator and click the one that says symbolab
Step-by-step explanation:
it can help for basically anything
Step-by-step explanation:
Let the two numbers be x and y
By the question
x + y = 87 ..... equation (I)
x - y = 65 ...... equation (II)
Now adding both equations we get
2x = 152
x = 152 / 2
Therefore x = 76
Putting x = 76 in equation i
76 + y = 87
y = 87 - 76
Therefore y = 11
The two numbers are 76 and 11.
Hope it helps :)
So it looks like the numbers are already in numerical order, that's good. The median is simply the middle number. I shouldn't have to help you find that. If there are 2 middle numbers, take the average and that's the median.
To find mean, you need a calculator. Add up all the numbers, and then divide by 10, since there's 10 numbers total. That's the mean.
The mode is 99, because that's the most frequent number. It appears twice.
The range is the span of the data set. To find this, take the largest number (99) and minus the smallest number (1). This is the range.
Answer:
Step-by-step explanation:
Given expression is:
First we will use the rule:
So for the given expression:
We will use tha property of multiplication on powers:
Applying the outer exponent now
In general and here, when we have an object with a constant cross section of area A, the volume V = A L, where L is the length.
L = V / A = 330 / 55 = 6 cm
Answer: 6 cm
