Answer: explain how to graph an equation in slope-intercept form.

Step-by-step explanation: To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=2x+3 tells us that the slope of the line is 2 and the y-intercept is at (0,3). This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.

If sin theta = 2/3 and tan theta <0 what is the value of cos theta?

Mrac [35]

Answer:

d) $\cos(\theta)=-\frac{\sqrt{5}}{3}$

Step-by-step explanation:

If $\sin(\theta)=\frac{2}{3}$ and $\tan(\theta)\:$ , then

$\theta$ is in quadrant 2.

Recall that;

$\sin^2(\theta)+\cos^2(\theta)=1$

We substitute the given sine ratio to obtain;

$(\frac{2}{3})^2+\cos^2(\theta)=1$

$\frac{4}{9}+\cos^2(\theta)=1$

$\cos^2(\theta)=1-\frac{4}{9}$

$\cos^2(\theta)=\frac{5}{9}$

$\cos(\theta)=\pm \sqrt{\frac{5}{9}}$

$\cos(\theta)=\pm \frac{\sqrt{5}}{3}$

We are in the second quadrant, therefore

$\cos(\theta)=-\frac{\sqrt{5}}{3}$

the sitting height (from the bottom of the seat to the top of the person's head) of female drivers is normally distributed with

Sindrei [870]

Answer:

B; 50%

Step-by-step explanation:

Here, we want to calculate the percentage of women that will not fit in the driver’s seat

We proceed as follows;

We start with calculating the z-score of this;

That would be ;

(x-mean)/SD

in this case;

x = 34 inches

mean = 34 inches

SD = 1.4 inches

Thus, we have that;

(34-34)/1.4 = 0/1.4 = 0

when z-score is 0, we are at the center of the distribution

A z-score of 0 corresponds to exactly 50%
