Use the exponent rule to simplify​
Serhud [2]

Answer:

y^{-5}

Step-by-step explanation:

The Exponent Quotient Rule states that if two terms of the same base are being divided by each other, then the simplified expression is the base to the first power subtracted by the second power. As an algebraic equation, that would be \frac{x^{a} }{x^{b} } =x^{a-b, where x is the common base and a and b are the exponents.

In this case, x=y, a=2, and b=7, so we know that \frac{y^{2} }{y^{7} } =y^{2-7}=y^{-5}. Hope this helps!

Fluoxetine, a generic anti-depressant, claims to have, on average, at least 20 milligrams of active ingredient. An independent l
san4es73 [151]

Answer:

t=\frac{18.7-20}{\frac{5}{\sqrt{80}}}=-2.326    

df=n-1=80-1=79  

p_v =P(t_{(79)}  

Step-by-step explanation:

Information given

\bar X=18.7 represent the sample mean for the content of active ingredient

s=5 represent the sample standard deviation for the sample  

n=80 sample size  

\mu_o =20 represent the value that we want to test

t would represent the statistic

p_v represent the p value for the test

System of hypothesis

We need to conduct a hypothesis in order to check if the true mean for the active agent is at least 20 mg, the system of hypothesis would be:  

Null hypothesis:\mu \geq 20  

Alternative hypothesis:\mu < 20  

The statistic would be:

t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}  (1)  

Now we can calculate the statistic:

t=\frac{18.7-20}{\frac{5}{\sqrt{80}}}=-2.326    

P value

The degrees of freedom are calculated like this:

df=n-1=80-1=79  

Since is a one left tailed test the p value would be:  

p_v =P(t_{(79)}

While making a jar, a potter removes part of a clay sphere and stores the clay from the removed part in a box with dimensions x
Sveta_85 [38]

Answer:

The correct answer to the following question will be "\frac{5\pi }{192} \ cubic feet".

Step-by-step explanation:

Give that the volume of the box = xyz cubic feet

Amount of jars which you can make = \frac{192xyz}{\pi }

Let the volume of the removed clay = V cubic feet

As we know,

Total \ number \ of \ jars=\frac{Volume \ of \ the \ box}{Volume \ of \ removed \ clay}

As we place the values in the equation above, we obtain

⇒                      \frac{192xyz}{5\pi}=\frac{xyz}{V}

When multiplication is applied we receive

⇒               V(192xyz)=5\pi \times xyz

⇒                       192V=5\pi

⇒                            V=\frac{5\pi }{192} cubic feet

if a shape is a regular pentagon with five sides, which of the following must be true? Check all that apply
julsineya [31]

Answer:

A. It has reflectional symmetry

B. It is symmetrical

D. It has five lines of symmetry

Step-by-step explanation:

we know that

A regular pentagon has 5 sides and 5 lines of symmetry. The number of lines of symmetry in a regular polygon is equal to the number of sides

Every regular polygon has reflectional symmetry

Regular polygons are symmetrical

therefore

A. It has reflectional symmetry ------> Is true

B. It is symmetrical -----> Is true

C. It has exactly one line of symmetry ----> Is false

D. It has five lines of symmetry -----> Is true
