A factor tree is a diagram used to determine the prime factors of a natural number greater than one.
Answer:
42x^2 - 7x - 6x + 1
42x^2 - 13x + 1 for FOIL method
To solve for x
7x - 1 = 0
7x = 1
x = 1/7
6x - 1 = 0
6x = 1
x = 1/6
Step-by-step explanation:
Note that there are 5 exams altogether: 4 hour exams and 1 final exam. Let the grade on the final be x.
The arith. mean of these 5 grades would be
<span>70+ 86+ 81 + 83 + x
</span> course grade = arith. mean = -------------------------------------

Answer: A.) For these data, as the number of at bats increases, the number of hits tend to increase.
This is because the points seem to trend upward as we move from left to right. This makes sense because the more attempts you get, the more hits you're expected to get.
Assume that someone has a batting average of 0.300; this means that if they got 1000 attempts, then we expect about 0.300*1000 = 300 hits. Now if they got 2000 at bats this time, then we expect about 0.300*2000 = 600 hits.
Of course things won't fit this perfectly since everything in life has random statistical error, but this gives a good idea of the upward trending data. The two variables (at bats and hits) are strongly related. We can say the variables have strong positive correlation.
Answer: She's spending less so she should buy it becasue it's less than her overall.
Step-by-step explanation:
$18,000
Rate is 7.5
years 5
Intrest= 18000x7.5x5/100=
180x7.5x5/1=$6750
Selling price= $18000+$6750=$24750
