Hello there,
Since one third eggs hatched, 1/3=2eggs. In order to find the total amount off eggs, 1/3+1/3+1/3:2+2+2=6.
Hope this helps!!

If random samples of size 525 were taken from a very large population whose population proportion is 0.3. The standard deviation

marissa [1.9K]

Answer: 0.02

Step-by-step explanation:

Given: Sample size : $n= 525$

The population proportion $P=0.3$

Then, $Q=1-P=1-0.3=0.7$

The formula to calculate the standard error is given by :-

$S.E.\sqrt{\dfrac{PQ}{n}}$

$\Rightarrow\ S.E.=\sqrt{\dfrac{0.3\times0.7}{525}}=0.02$

Hence, the standard deviation of the sample proportions (i.e., the standard error of the proportion) is <u>0.02</u>.

When 27 times x squared times z all over negative 3 times x squared times z to the sixth power is completely simplified, the exp

marysya [2.9K]

Answer:

-5 or 5 depending on how you write the simplified form

Step-by-step explanation:

$\dfrac{27x^2z}{3x^2z^6}=9x^{2-2}z^{1-6}\\\\\boxed{=9z^{-5}=\dfrac{9}{z^5}}$

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

1/a^b = a^-b

Some folks like their simplified form to contain only positive exponents. Other folks avoid unnecessary fractions. Choose the form that satisfies your grader.
