Answer:
X = 10 Y = 14
Step-by-step explanation:
Okay, so. If you divide the Y and X for example 2.8 divided by 2 is 1.4 5.6 divided by 4 is 1.4. So like it says it is proportional. So, when you get down to the eight. You can see they are adding the X by 2 so the X is 2. The Y would be 2.8. So, you would add 2.8 into 11.2. That would be 14.
Hope this helps!
Answer:
(a) 99%
(b) 50%
Step-by-step explanation:
(a) All factorials after 1! have 2 as a factor, so are even. Thus 99 of the 100 factorials are even, for a probability of 99%.
__
(b) The first two sums are odd; the next two sums are even. The pattern repeats every four sums. There are 25 repeats of that pattern in 100 sums, so 2/4 = 50% of sums are even.
Answer:
Q = P - n(x/100)
Step-by-step explanation:
P is the total number of lace edging, n is the number of times the length x is cut from P, and Q is the remnant of the reduction.
So the number of x length is subtracted from P and must be converted to meters (since it is in centimeters) to get Q. That is;
Q = P - n(x/100)
Answer:
x = 4
Step-by-step explanation:
4x+2=18
subtract 2 to both sides
2 cancels out
4x=16
divide both by 4
4 cancels out
x= 4
