Answer:
Step-by-step explanation:
Given the legs of right angled triangle 4 and 5 units. we have to find the length of hypotenuse.
By Pythagoras theorem,
In right angled triangle the square of the length of the hypotenuse is equal to sum of squares of the lengths of other two sides
Hence, 
If 5 pens cost 95 cents, that means that each pen cost 95/5 = 19 cents each. So a dozen will cost:
dozenCost = 12*19 = 228 cents
Answer:cant see it
Step-by-step explanation:
1) Solve the first inequality
3y ≤ 2x + 6
=> y ≤ 2x/3 + 2
2) Draw the line y = 2x/3 + 2
3) Shade the region below the line y = 2x/3 + 2
4) Solve the inequality 2x + y > 0
=> y > - 2x
5) draw the line y = -2x
6) Shade the region above the line y = -2x
7) The solution is the region between the two lines shaded including the portion of the line y = 2x/3 + 2
Using it's concept, it is found that the probability of guessing the right combination in one try’s is of 
.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there are 4 dials, each with a 
probability of getting it correct, hence the probability of getting the right combination is given by:
