What is the mode for the set of data?

ozzi

The mode of given data set is 74. Option D is correct option.

Step-by-step explanation:

We need to find mode of the data set

The data according to key is: 5|0 = 50 years old

So, data will be:

50,54,56,60,62,63,64,68,68,69,70,72,73,74,74,74,78,79,84,85,86,88

Mode is the most repetitive value in the data set.

So, the most repetitive value is 74.

The mode of given data set is 74. Option D is correct option.

2x+14= -21-5x<br> Need to find out what x is but a step by step explanation please

adoni [48]

Notice how on both sides of the equation there is one coefficient (number being multiplied by x) and a constant (just a plain number). You want all constants to be on one side and all coefficients on the other. He’s how do to that:
2x+14=-21-5
I am choosing that all constants will be on the right side, so I will do the inverse operation of any constant on the left side to remove it. Here, a constant on the left side is 14. I will subtract 14 from both sides of the equation. Positive 14 minus 14 is zero, so it cancels out and removes it.
2x+14-14 = -21-5x
2x = -35-5x
See how the 14 is now gone? The equation looks much simpler now. Okay next, you can see that there is a coefficient on the “constant side” that I’ve chosen, so I am going to remove that. Negative 5 plus positive 5 equals zero. Do this on both sides of the equation.
2x+5x = -35-5x+5x
7x = -35
Now the equation is just two numbers. All that is left to do is divide by the last coefficient, 7, in this case.
7x/7 = -35/7
x = -5
