Answer:

Option C is right.

Step-by-step explanation:

Resultant vector is the sum of two vectors.

i.e. addition of horizontal component and addition of vertical components.

For example, if ai+bj is one vector and ci+dj be another vector,

resultant vector = a+ib+c+id

= (a+c)+i(b+d)

i.e. option c is right

Ksju [112]

Answer:

n≅376

So sample size is 376.

Step-by-step explanation:

The formula we are going to use is:

n=pq(\frac{z_{\alpha/2}}{E})^{2}

where:

n is the sample size

p is the probability of favor

q is the probability of not in favor

E is the Margin of error

z is the distribution

α=1-0.98=0.02

α/2=0.01

From cumulative standard Normal Distribution

z_{\alpha/2}=2.326

p is taken 0.5 for least biased estimate, q=1-p=0.5

n=0.5*0.5(\frac{2.326}{0.06})^{2}\\n=375.71

n≅376

So sample size is 376

Can someone give 2 examples of a logarithmic equation with infinite solutions?
Vika [28.1K]

Assuming what is meant by "infinite solutions" are infinite number of solutions of a logarithmic equation.  

\frac{1}{2}\log x^2 - \log \sqrt{x} - \log \sqrt{x} = 0

and

\frac{1}{2}x-2\ln e^x=-\frac{3}{2}x
