What is the ratio 175 to 250 written in fraction in LOWEST TERMS?
Lana71 [14]
For 175 : 250 divide them both by 25 to get \frac{7}{10} < \frac{175}{250}
25 goes into 175 > 7 times > 25 into 250 is 10 times! > \frac{7}{10}
For the second one 16 : 40 just divide the top and bottom by 8 since 8 is a common factor of both which will give us \frac{2}{5}.
8 goes into 16, 2 times and 40, 5 times.

Applying Properties of Exponents In Exercise, use the properties of exponents to simplify the expression.
NemiM [27]

Answer: (a) e^3

(b) e^{10}

(c) \dfrac{1}{e^4}

(d) e^{4}

Step-by-step explanation:

Properties of exponents :

1) a^m\times a^n=a^{m+n}

2) \dfrac{a^m}{a^n}=a^{m-n}

3) (a^m)^n=a^{mn}

4) a^{-n}=\dfrac{1}{a^n}

Now , we simplify the given expression using the above properties.

a) (e^6)(e^{-3})

=e^{6+(-3)}   [By property (1)]

=e^{6-3}=e^3  [∵ (+)(-)=(-)]

b) (e^{-2})^{-5}

=e^{-2\times-5}  [By property (3)]

=e^{10}   [∵ (-)(-)=(+)]

c) (\dfrac{e^6}{e^2})^{-1}

=(e^{6-2})^{-1}    [By property (2)]

=(e^{4})^{-1}  

=\dfrac{1}{e^4}       [By property (4)]

d) (e^3)^{\frac{4}{3}}

=e^{3\times\frac{4}{3}}        [By property (3)]

=e^{4}

Test Scores Find the percentile rank for each test score in the data set. Round to the nearest whole percentile.
photoshop1234 [79]

The percentile rank for 10 will be 10th.

<h3>What is percentile rank?</h3>

The percentile rank of a particular score in statistics refers to the percentage of scores in the frequency distribution that are smaller than that score.

Percentile rank = [(Number of values below x) + 0.5]/ total number of values * 100

For 10,

Percentile rank = {[0 + 0.5]/5} x 100 = 10th

For 15,

Percentile rank = ([1 + 0.5]/5) x 100 = 30st

For 19,

Percentile rank = [2 + 0.5]/5 x  100 = 50th

For 23,

Percentile rank = [3 + 0.5]/5  x  100 = 70th

For 30,

Percentile rank = [4 + 0.5]/ 5  x 100 = 90th

The percentile rank for 10 will be 10th.
