Answer:

The product of given expressions is y^{18}.

Step-by-step explanation:

The given expression is

(y^2)^5\cdot y^8

Use the properties of exponent to find the product.

(y^2)^5\cdot y^8=y^{10}\cdot y^8        [\because (x^m)^n=x^{mn}]

(y^2)^5\cdot y^8=y^{10+8}        [\because x^mx^n=x^{m+n}]

(y^2)^5\cdot y^8=y^{18}

Therefore the product of given expressions is y^{18}.

For a population with a mean of u = 40 and a standarddeviation of o = 8, find the z-score corresponding toeach of the following
ivann1987 [24]

Solution:

Given the mean and standard deviation;

\mu=40,\sigma=8

The z-score formula is;

z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}

(a)

\begin{gathered} x=34,n=1 \\  \\ z=\frac{34-40}{\frac{8}{\sqrt{1}}} \\  \\ z=-0.75 \end{gathered}

(b)

\begin{gathered} x=34,n=4 \\  \\ z=\frac{34-40}{\frac{8}{\sqrt{4}}} \\  \\ z=-1.5 \end{gathered}

(c)

\begin{gathered} x=34,n=16 \\  \\ z=\frac{34-40}{\frac{8}{\sqrt{16}}} \\  \\ z=-3 \end{gathered}

2 tenths is equal to____ fifths
Sunny_sXe [5.5K]
To solve this, it is easiest to set up a proportion, letting x represent the number that we don't know.

2/10 = x/5

Now, we can use cross products to simplify this proportion.  Cross products sets the products of the numerator and denominator of separate fractions equal to one another.  It results in the equation:

(5)(2) = (10)(x)

Let's multiply out these numbers to further simplify the equation.

10 = 10x 

Finally, we have to divide both sides by 10, to get our variable x alone

x = 1

Therefore, 2 tenths is equal to 1 fifth.
