Answer:

The total number of pages in the e-book is 240.

Step-by-step explanation:

Given:

Logan has completed 75%

Logan has read 180 pages

To Find:

The total number of pages in the e-book= ?

Solution:

Let X be the total number of pages on the e-book

then

=> 75% of X = 180

Now lets find the value of X

X = $\frac{180}{75\%}$

X = $\frac{180}{\frac{75}{100}}$

X = $\frac{180}{0.75}$

X = 240

let the two amounts invested by 3x and 7x

(notice 3x : 7x = 3 : 7 )

then 3x + 7x = 200

10x = 200

x = 20

then 3x = 3(20) = 60

and 7x = 7(20) = 140

60+140=200

Descriptive Statistics, as the name says, describes, properties or characteristics (that can be gathered through surveys and case studies), using mathematical methods for tendency and dispersion.

Inferential statistics, as the name states, infers, if samples from a larger data set have behaviors that can be then extrapolated to the larger group.

Hailey, Megan, and Bailey have saved $458 for a summer trip to the beach. Hailey has saved $167. Megan has saved at least $152,

Jet001 [13]

Let H = Hailey, M = Megan, B = Bailey

H + M + B = 458
167 + M + B = 458
M + B = 291

152 ≤ M ≤ 164
If M = 152, B = 139
If M = 164, B = 127

Thus,
$127 ≤ B ≤ 139
