Solve each equation by completing the square 2q^2+8q=3

3241004551 [841]

Answer:

Divide by 2

q^2+4q=3/2

q^2+4q(4/2)^2=3/2+(4/2)^2

(q+4/2)^2=3/2+16/4

taking the square root of both side

√(q+4/2)^2=√(3/2+16/4)

Note that the square will cancel the square root then you will take LCM on the right hand side

q+4/2=√6+16/4

q+4/2=√22/4

q= -4/2+-√22/4

q=(-4+_√22/4)

Lemons tastes sour to some people. This sourness is inherited through the TAS2R38 gene. About 65% of the population has this gen

Minchanka [31]

Answer:

We are given:

$\hat{p}=0.65$

Margin of error $E=0.02$

Confidence level = 0.99

We need to find the sample size to estimate the proportion of people who carry the TAS2R388 gene.

The formula for finding the sample size is:

$n=\hat{p} (1-\hat{p})\left (\frac{z_{\frac{0.01}{2}}}{E} \right )^{2}$

Where:

$z_{\frac{0.01}{2}}=2.576$ is the critical value at 0.01 significance level.

Therefore, the required sample size is:

$n=0.65(1-0.65) \left(\frac{2.576}{0.02} \right)^{2}$

$=0.2275 \times 16589.44$

$=3774.1 \approx 3774$

Therefore, the required sample size is 3774
