7 7/8 can be estimated to 8
2 2/11 can be estimated to 2
8 + 2 = 10
7 7/8 = 56+7/8 = 63/8
2 2/11 = 22+2/11 = 24/11
63/8 + 24/11 = 693+192/88 = 10.06
So do you see how similar 10 and 10.06 are to each other? :)
Is this what your looking for?
First compute the component form of vector u by subtracting its initial values from terminal values. 18-1=17, 6-(-12)=18. So u=(17, 18). Since v points in the opposite direction, and has a magnitude three times that of u, we multuply the u by -3 and get v=(-3*17, -3*18)=(-51, -54).
Answer: random sampling
Step-by-step explanation: Random sampling is where each member of the sample is randomly selected from the population. Since Josh chose every third female customer, he randomly chose the sample.
Answer:
x = -18
Step-by-step explanation:
1/2x = -9
(21)1/2x = -9(2/1)
x = -9/1(2/1)
x = -18/1
x = -18
1 over 1/2 will simplify into 2. 2/1 simplifies into 2. All we are doing is just dividing by 2 on both the denominator and numerator. So if we want the 1/2 into a whole number, just multiply it by 2 on both sides which then you get 2/1 which simplifies into 2. So the answer is 2. Hope this helps and answers your question!
