Which graph has a slope of 1/2?

Mathematics

Answer: Bottom left graph

Step-by-step explanation: a slope is the degree of change in the y-axis divided by the degree of change in the x-axis. Therefore, d(y) / d(x) = 1 / 2

d(x) = 2 d(y)

Meaning for every two steps taken along the y-axis, one step is taken along the x-axis.

Solving for slopes according to individual scales, the bottom right and top left graphs both have a slope of ¼

The top right graph has a slope of 1

Bottom left has a slope of ½, which is correct. Solving, we have:

d(y) / d(x) = (5 - 2½) / (20 - 10) = ½

A slope of 1/2 means for every two units to the right we move up one.

We have to be careful here because the graphs don't always use the same scale for x and y.

The bottom left uses the same scale and does indeed go two units to the right for every unit up, so that one is the answer.

Alchen [17]

Step-by-step explanation:

The slope of a line characterizes the direction of aline. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .

You observe a portfolio for five years and determine that its average annual return is 13% and the standard deviation of its ret
horrorfan [7]

Answer:

There is a 95% probability that the portfolio would not loose more than 30% of its value.

Step-by-step explanation:

The confidence interval for proportions (<em>p</em>) is:

CI=\hat p\pm z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}

The information provided is:

\hat p = 0.13\\\sqrt{\frac{\hat p(1-\hat p}{n}} =0.21

For 95% confidence level the critical value of <em>z</em> is:

z_{\alpha/2}=z_{0.05/2}=z_{0.025}=1.96

The 95% confidence interval for average annual return is:

CI=\hat p\pm z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}\\=0.13\pm 1.96\times0.21\\=0.13\pm 0.4116\\=(-0.2816, 0.5416)\\\approx(-28\%, 54\%)

The lower limit of the 95% confidence interval is -28%.

This implies that the portfolio would not loose more than 28% of its value.

Thus, there is a 95% probability that the portfolio would not loose more than 30% of its value.

4 + 2p = 12<br><br> so p = what
erma4kov [3.2K]

Answer:

p=4

Step-by-step explanation:

4+2p=12

Step 1: Simplify both sides of the equation.

2p+4=12

Step 2: Subtract 4 from both sides.

2p+4−4=12−4

2p=8

Step 3: Divide both sides by 2.

2p/2=8/2

p=4

Answer:

p=4

1) Solve ;
Rashid [163]

Answer:

x ≤ 7/2

Step-by-step explanation:

Expand brackets:                   3x - 15 ≤ x - 8

Subtract x from both sides:   2x - 15 ≤ -8

Add 15 to both sides:                    2x ≤ 7

Divide both sides by 2:                   x ≤ 7/2
