lions [1.4K]

Answer:

The population proportion of households that own at least one snow blower is 0.104.

Step-by-step explanation:

In order to find the population proportion of households that own at least one snow blower, you have to divide the number of people that said they owned at least one snow blower by the number of households surveyed:

26/250=0.104

According to this, the answer is that a point estimate for p, the population proportion of households that own at least one snow blower is 0.104.

What is the period for the function y = -4 cos (5x +3)? (4.3)

BlackZzzverrR [31]

The periodicity of function is $\frac{2 \pi}{5}$

<em><u>Solution:</u></em>

Given that we have to find the period of function

<em><u>Given function is:</u></em>

$y = -4 + cos(5x+3)$

<em><u>Use the below formula:</u></em>

$\mathrm{Periodicity\:of\:}a\cdot \cos \left(bx\:+\:c\right)\:+\:d=\frac{\mathrm{periodicity\:of}\:\cos \left(x\right)}{|b|}$

Thus,

$Peridocity\ of\ cos(5x + 3) - 4 = \frac{\text{periodicity of cos(x)}}{5}$

Now find the periodicity of cos(x)

We know that,

periodicity of cos(x) = $2 \pi$

Therefore,

$Peridocity\ of\ cos(5x + 3) - 4 = \frac{2 \pi}{5}$

Thus the periodicity of function is $\frac{2 \pi}{5}$
