Mathematics
1 answer:
wolverine [178]3 years ago
5 0

Answer:

Only the mean increased.

Step-by-step explanation:

The mean is the total divided by the number of scores, and since adding 21 will increase the total score significantly, the mean increases.

The median is still 7.

What does a star mean after a number
Triss [41]
A star is written to show multiplication. It is a replacement for a dot or a x which is what you probably learned to be the "times" sign. In upper level maths, the "x" is replaced with a " * " to make it more legible and to avoid confusion with the variable "x".

steven can type 160 words in 2 minutes and 30 seconds at this rate, how many words can he type in 4 minutes?
Gnom [1K]

Answer:

hello : 256 words

Step-by-step explanation:

4 minutes = 4 ×60 = 240 seconds

240 seconds → x ?

x = (160×240) / 150 = 38400/150= 256 words

To compare 5 in tens place to 5 in the hundreds place in the number 5,555
galina1969 [7]

Answer:

I'm not sure what you are asking for?

Step-by-step explanation:

The 5 in the tens place = 50, and the 5 in the hundreds place = 500.

To compare them (Are you asking me for the difference between them???), then, 500 - 50 = 450.

But, again, I'm not sure what you want.
