Answer:
464
Step-by-step explanation:
Insert x = -1 and y = 4 into the first inequality:-
4 <= -(-1) + 4 = 5
so this fits
Its A
It is 52. Here is why...
<span>5 + 6 x 3 + (7 - 3) x (16 divided by 2) - 3
</span>= 5+18+4 <span>x 8-3
=5+18+ 32-3
=23+32-3
=55-3
=52

Answer:
5 months
Step-by-step explanation:
One cellphone provider charges AED10 per month plus an activation fee of AED20.
If I used the services of this cellphone provider for x months, total charges for the services,
y = 10x + 20 --------(1)
Similarly, charges for the second cellphone provider for x months of uses will be,
y = 11x + 15 -------(2)
Input-output table for equation (1)
x 1 2 3 4 5
y 30 40 50 60 70
Input output table for equation (2)
x 1 2 3 4 5
y 26 37 48 59 70
From these tables, we find (5, 70) is a common point for both.
It reveals that after the uses of 5 months charges for both the cellphone providers will be same (y = $70)
Experimental is the actual measured desiredoutcome/totaltrials
total trials=10+12+28=50
green is 28
so 28/50 or 14/25 is the experimental proablity of doing green
theoretical is desired/total possible,
total possible=total number of marbles=5+8+12=25
desired=8, so 8/25 is theoretical probablity of draing green
I would expect the experimental proabblity to approach the value of the theoretical proabblity, not sure why tho
