Complete the equation for the linear function whose graph contains the point (-1,2) and has a slope of 0.9.

1 answer:

4 0

Plug it into point-slope form.

y - y1 = m(x - x1)

Where y1 is the y-value of the point, x1 is the x-value, and 'm' is the slope.

So plug in -1 for x1, 2 for y1, and 0.9 for 'm':

y - 2 = 0.9(x + 1)

Simplify to get in slope-intercept form:

Distribute 0.9 into the parenthesis:

y - 2 = 0.9x + 0.9

Add 2 to both sides:

y = 0.9x + 2.9

The area of a triangle is 1,440 cm2. The base of the triangle is 5 times the height. What is the height of the triangle?

madam [21]

Answer: 24 cm

Step-by-step explanation:

The formula for calculate the area of a triangle is:

$A=bh/2$

Where b is the base and h is the height.

Then if the base of the triangle is 5 times the height:

$b=5h$

Substitute the above into the formula and solve for the height. Therefore, you obtain that the height is:

$1,440=\frac{5h*h}{2}\\1,440=\frac{5h^{2}}{2}$

$1,440cm^{2}=5h^{2}/2\\h=\sqrt{\frac{2(1,440)}{5}}\\h=24cm$

Reporting cheating What proportion of students are willing to report cheating by other students? A student project put this ques

KonstantinChe [14]

Answer:

0.1105

Step-by-step explanation:

We know that question about reporting a cheating is asked to 172 students.

So the sample size would be n=172.

Out of 172 undergraduate students only 19 students answered "yes". It means that only 19 out of 172 students are willing to report cheating and so x=19.

According to definition of proportion

proportion=number of favorable outcome/total number of outcome

p=x/n

we are given that x=19 and n=172 so,

p=19/172=0.1105.

Hence according to given data 11.05% of students are wiling to report cheating by other students.
