Answer: 104 pages
Step-by-step explanation:
On 1/4 is actually 2/8 so on Monday and Wednesday together she read 3/8 + 2/8 = 5/8 of the 352 pages and 5/8 x 352 = 220.
Tuesday she read 28 pages so she has read 220 + 28 = 248 pages.
She must read 352 -248 = 104 pages more
8x > x = 0.5
8(0.5) = 4 is the answer

Answer:
(1)
(2)
Step-by-step explanation:
Solving (1):
(a): Mean
This is calculated as:
So, we have:
Solving (b): The variance
This is calculated as:
Where:
and
So, we have:
So, we have:
Solving (c): The standard deviation.
This is calculated as:
Solving (2):
(a): Mean
This is calculated as:
So, we have:
Solving (b): The variance
This is calculated as:
Where:
and
So, we have:
So, we have:
Solving (c): The standard deviation.
This is calculated as:
For mean:
119 + 139 + 149 + 179 + 189 + 199 + 209 = 1183
1183/7 (for the amount you added) = 169
For median:
119, 139, 149, 179, 189, 199, 209.
Find the middle number: 179 (is your median)
For mode:
119, 139, 149, 179, 189, 199, 209
Find the number that shows up the most: N/A (they all only show up once)
I believe Median will be your best choice (it has the closest answer to 189)
hope this helps
