sinx-cosx=0

sinx=cosx

tanx=1

therefore

x=π/4

x=π-π/4

Hope this helps

Answer:

We multiply by 2 and add 4

Step-by-step explanation:

To find the pattern, we find the slope

m = ( y2-y1)/(x2-x1)

m = ( 10-6)/(3-1)

m = 4/2

m =2

We are multiplying by 2

y = mx+b where m is the slope and b is the y intercept

y = 2x+b

Using the point (1,6)

6 = 2(1)+b

6 = 2+b

The y intercept is 4

y = 2x+4

We multiply by 2 and add 4

Doss [256]

Answer: The coefficient of determination = 0.6291

Step-by-step explanation:

Given: Total variation is 24.488, the explained variation is 15.405, and the unexplained variation is 9.083.

The coefficient of determination is computed as:

$\text{ coefficient of determination} =\frac{\text{explained variation }}{\text{total variation}}$

Substituting given values, we get

$\text{coefficient of determination} =\frac{15.405}{24.488}$

$=0.6291$

Therefore, the coefficient of determination = 0.6291

Mnenie [13.5K]

<h2>Answer with explanation:</h2>

As per given , we have

$\ovreline{x}=8.17$

$\sigma=2.2$

n= 64

a) Since , the sample mean is the point estimate for the population mean.

Therefore, the point estimate of the population mean = $\ovreline{x}=8.17$

b) Critical z-value for 99% confidence : $z_{\alpha/2}=2.576$

Confidence interval :

$\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

$8.17\pm (2.576)\dfrac{2.2}{\sqrt{64}}$

$8.17\pm 0.7084$

$(8.17-0.7084,\ 8.17+0.7084)=(7.4616,\ 8.8784)\approx (7.46,\ 8.88)$

Hence, the 99 percent confidence interval for the population mean is between 7.46 and 8.88.
