Answer:

I have given it step by step below.

Step-by-step explanation:

(i) Mean = sum of observations/total no. of observation

= 23 + 20  + 4 + 19 + 28 + 35 + 25 + 0  +1 + 30/ 10

= 185/10

= 18.5

(ii) additional 35 runs

New Mean

=previous total  + 35/10 + 1     (the 1 gets added in denominator because of                                           the additional observation)

= 185 + 35/11

= 220/11

= 20

Hope this helps you!

Jasmin read 1 3/4 pages in one minute. Armando read 1 1/2 times the number of pages that Jasmin read. How many pages did Armando
bekas [8.4K]
Armando reads 7/8 pages, since u said ''times'' that calls for multiplication so jasmine reads 1 3/4 and Armando reads 1/2 times that so that means 1/2 * 1 3/4 = 7/8. So in conclusion, Armando reads 7/8 pages total.

Hope this helps and if it does, happy studying and don't forget to mark as brainliest.

PLEASE I NEED AN ANSWER ASAP!!
valentina_108 [34]

The answer is C -3•(-5)=15

The process of elimination would’ve been helpful because two negatives equal a positive and one negative equals a negative, therefore you could get rid of B and D. Also, for answer A the diagram already tells you that each entity is negative, so there should be no positive numbers in the equation (besides from the answer possibly). I hope that made sense.
