Answer:\ \boxed{5^2}

\sqrt[n]{a}=a^\frac{1}{n}\\\\\text{therefore}\\\\\sqrt5=5^\frac{1}{2}\\----------------\\25=5^2\\----------------\\78,125=5^7\\----------------\\\text{use}\\\\a^n\cdot a^m=a^{n+m}\\\\\dfrac{a^n}{a^m}=a^{n-m}\\----------------\\\\\dfrac{\sqrt5\times78,125}{25\times5^{\frac{7}{2}}}=\dfrac{5^\frac{1}{2}\times5^7}{5^2\times5^\frac{7}{2}}=\dfrac{5^{\frac{1}{2}+7}}{5^{2+3\frac{1}{2}}}=\dfrac{5^{7\frac{1}{2}}}{5^{5\frac{1}{2}}}=5^{7\frac{1}{2}-5\frac{1}{2}}=\boxed{5^2}

Order decimals from least to greatest .. 1.09, 1.901,1.9,1.19
Nuetrik [128]
The easiest way to do this is to write the decimals with equal amount of places after the dot and you'll see it more clearly:

1.09 = 1.090
1.901 = 1.901
1.9 = 1.900
1.19 = 1.190

So from the least to the greatest:

1.090
1.190
1.900
1.901

In a form you gave at the beginning:

1.09 < 1.19 < 1.9 < 1.901

vovangra [49]

Answer:

You can make NO triangles.

When given 3 sides of a triangle, The longest side must be LESS than the sum of the other 2 sides.

Longest Side = 50 cm

50 is NOT less than 14 + 10, therefore, we have no triangle.

A true-false quiz with 10questions was given to a statistics class. Following is the probability distribution for the score of a
SSSSS [86.1K]

Using the mean <u>formula and it's interpretation</u>, it is found that:

1. The mean is 7.52.

2. If we were to give this quiz to more and more students, the mean score for these students would approach 7.52.

The mean of a discrete distribution is given by the <u>sum of each outcome divided by it's respective probability</u>.

Hence, in this problem, according to the <u>distribution given</u>, the mean is:

E(X) = 5(0.06) + 6(0.12) + 7(0.33) + 8(0.29) + 9(0.13) + 10(0.07) = 7.52

The mean is 7.52.

The <em>interpretation </em>is that over many trials, the mean would approach 7.52.
