Answer:
B should be correct
Step-by-step explanation:
Because you're trying to make them congruent, equal the two expressions to each other.
So, for #10 you would equal them so it would look like this.
2x+2=5x-19
Then you would just go ahead and simplify
2x+2=5x-19
-2x -2x
---------------
2= 3x -19
+19 +19
---------------
21=3x
--- ----
3 3
x=7
This means that x should be 7. You can check this just by plugging it in
2x+2
2(7)+2 = 16
5x-19
5(7)-19= 16
Same with #11.
x+8=3x-14
-x -x
--------------
8=2x-14
+14 +14
--------------
22=2x
--- ----
2 2
x=11
Check.
x+8
11+8= 19
3x-14
3(11) - 14 = 19
Answer: 8/17
Explanation:
We'll need the pythagorean theorem to find the missing side length.
Now we can compute the cosine ratio.
cos(angle) = adjacent/hypotenuse
cos(W) = VW/UW
cos(W) = 8/17
The initial investment was 1200 4percent a year is 48 dollars is 240 for 5 years add 1200 +240 =1440
Sorting the data from smallest to largest is a useful first step that makes calculating Median and Mode easier
We know, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution.
The mode is the value that appears most often in a set of data values. If X is a discrete random variable, the mode is the value x at which the probability mass function takes its maximum value.
So, when we sorting the data from smallest to largest is a useful first step that makes calculating the median easier. Because median is the middle term of the ordered data set.
Similarly, It will be easier to find the most frequent in the ordered data set
that is mode
Hence, sorting the data from smallest to largest is a useful first step that makes calculating Median and Mode easier
