Answer:

Step-by-step explanation:

1.)

we see that when x=0 y=0 which means that our equation

y=mx+b

b=0

(this is shown if we plug in 0 for x)

0= 0x+b

0=b

Next, we notice that each time it's increasing by four which means our slope is just 4

the answer is 4x

The y intercept (or b) is the same deal as question one

we can also see that when x=1 y=3 which means that

3=x+0

3=x

our slope is 3

A student wants to check six websites. Four of the websites are social and two are school-related. After checking just two sites

mash [69]

The approximate probability that she checked a social website first, then a school-related website is 0.267.

First step is to calculate the Total number of websites

Total number of websites=Number of school websites+Number of social websites

Total number of websites=2+4

Total number of websites=6

Second step

Probability of checking the social website first

Probability of checking social website=Number of social websites/Total number of websites

Probability of checking social website= 4/6

Third step

Since one social website is checked which means that she is left with 3 social website and 2 school websites

Total number websites=2+3

Total number websites=5

Forth step

Probability of checking social website=Number of school websites/Total number websites

Probability of checking social website=2/5

Fifth step

Probability= 4/6 x 2/5 = 0.2666

Probability=0.267(Approximately)

Inconclusion the approximate probability that she checked a social website first, then a school-related website is 0.267.

Step-by-step explanation:

Corresponding sides are proportional. Sides with the same mark are the same length.

WX/XY = LM/MN = LM/KJ

WX/10 = 18/15

WX = 180/15 . . . . multiply by 10

WX = 12

One leg of a right triangle measures 6 inches. The remaining leg measures 6√3 inches. What is the measure of the angle opposite

Simora [160]

30°
Here's why:
Using the well-known Pythagorian theorem we can reckon how long the hypotenuse is:
c^2=6^2+36*3 -> c=12
Knowing that sin(a)=a/c=6/12=0.5 the measure of the angle in degrees is 30°
Hope could help :)
