X+2y, if X=-2 and Y=4
Answer:
6
Step-by-step explanation:
X=-2
Y=4
X+2y
= -2 + 2(4)
= -2 + 8
= 6
the answer is:
6
because:
X=-2
Y=4
X+2y
= -2 + 2(4)
= -2 + 8

Find length
__
AB
A:-6
B: 8
To find the distance between those two points you would need to
do, -6 - (8), which is -14, and than take away the minus sign, and the length of AB is 14 units.
Answer:
14 = AB
Step-by-step explanation:
When finding length, absolute value is the way to go! So if A is -6 and b is 8, then we need to find the distance between them. You can physically count on a number line like I see you did, which would be -5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8=14 numbers
or you can set up the expression---
| -6-8 |
which equals
| -14 |
or
14
because 14 is the same as | -14 |
what's 4 divided by 5/7 as a mixed number in its simplest form
Answer:
8[tex]\frac{1}{7}[/tex] (in mixed fraction)
Step-by-step explanation:
4 ÷ [tex]\frac{5}{7}[/tex]
can also be written as
[tex]\frac{4}{1}[/tex] ÷ [tex]\frac{5}{7}[/tex]
[tex]\frac{4}{1}[/tex] ×[tex]\frac{7}{7}[/tex] [tex]\frac{5}{7}[/tex] × [tex]\frac{1}{1}[/tex] (to do the denominators same)
[tex]\frac{28}{7}[/tex] ÷ [tex]\frac{5}{7}[/tex]
= [tex]\frac{28/5}{7}[/tex]
= [tex]\frac{5.6}{7}[/tex]
= [tex]\frac{5.6}{7}[/tex] × [tex]\frac{10}{10}[/tex] (to remove the decimal point)
= [tex]\frac{56}{7}[/tex]
= 8[tex]\frac{1}{7}[/tex] (in mixed fraction)

Four speed skaters, Marco, Naim, Oliver, and Pedro, compete in a relay race where they all agree that Naim will be the last skater. Then, they try to decide whether or not Oliver should be the first skater in the race.
Which subset, A, of the sample space shows the complement of the event in which Oliver is the first skater in the race?
A = {MOPN, PMON}
A = {OPMN, OMPN}
A = {MOPN, MPON, OPMN, POMN}
A = {MOPN, MPON, PMON, POMN}
Answer:
A = {OPMN, OMPN}
Step-by-step explanation:
If Olivers first and Naims last that's the only one that fits
Hope this helps, please leave any questions or concerns in the comments. Thanks
A = {MOPN, PMON} is the subset of the sample space shows the complement of the event in which Oliver is the first skater in the race
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The sample space of the relay race is the set of all possible arrangements of the four skaters, which can be represented by the permutations of the set {M, N, O, P}.
Since Naim is the last skater, there are 3! = 6 possible arrangements of the other skaters in front of him.
The event in which Oliver is the first skater in the race can be represented by the set {OMPN, OPNM, ONPM, ONMP}, which contains 4 possible arrangements.
The complement of this event is the set of all arrangements where Oliver is not the first skater, which can be represented by the set A.
Since there are 6 possible arrangements and 4 of them have Oliver in the first position, there are 6 - 4 = 2 arrangements in A.
A = {MOPN, PMON} is the complement
Hence, A = {MOPN, PMON} is the subset, A, of the sample space shows the complement of the event in which Oliver is the first skater in the race

Combine like terms
7x+2 = 2x+13
Subtract 2x from each side
7x+2-2x = 2x+13-2x
5x+2 = 13

5x+2-2 = 13-2
5x = 11
Divide each side by 5
5x/5 = 11/5
x = 11/5
Answer:
2.2

An angle measuring 60 degrees is measured as 62 degrees. What is the percentage error correct to 3 significant figures?
Answer:
3.33%
Step-by-step explanation:
60 = theoretical/actual degree measure
62 = experimental/calculated degree measure
% error = (|actual - calculated|/actual)*100
In words, the absolute value of the actual value minus the calculated value is first calculated. Then, divide the difference by the actual value that you should have obtained. Since you want this converted to a percent, multiply the decimal value of your quotient by 100.
Three significant figures is 3.33 because none of these numbers are leading or trailing zeros. If you count how many numbers (that are not leading or trailing zeros) the value 3.33 has, you'll find 3 significant figures, which is why your final answer should be 3.33%.
