vivado [14]

For this problem, you are to multiply the numbers and add the exponents for the variables

10*3= 30
x*x^4= x^5
y^5*y^6= y^11
z^3*z^3= z^6

the answer to the question is 30x^5y^11z^6

Can someone help me with this ????

Answer:

$(\frac{3}{3+5})(2 - (-14))+ (-14)$

Step-by-step explanation:

Given

Ratio = 3:5

Q = -14

S = 2

Required

Which solution uses $(\frac{m}{m+n})(x_2 - x_1)+ x_1$

From the given parameters;

$m:n = 2:5$

$m = 2\ and\ n = 5$

$x_1 = -14\ and\ x_2 = 2$

Substitute the above values in $(\frac{m}{m+n})(x_2 - x_1)+ x_1$

This gives:

$(\frac{m}{m+n})(x_2 - x_1)+ x_1$

$(\frac{3}{3+5})(2 - (-14))+ (-14)$

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>.
