2 answers:

7 0

Ok to find out which is the answer you haev to plug in the points you have one by one in the x and y to see which point is the one that makes both equations true
E.J. 1-7=4 we automatically know that the first one is not true because 1-7 is not 4 so lest go with letter b
-2+4=4 we can cancel out letter b to because -2+4 does not equal 4 so lets check letter c
2+2=4 now we can see that this one is correct but before we call wins lets check if the second equation is also true 2-2=-6 this doesnt equal -6 so answer c can't be correct because even tho the first equation was true the second was not so it doesn't qualify... lets try our last option -1+5=4 this does equal 4 lets check the second equation to see it its true -1-5=-6 this is also true... this means that your answer would be letter D

List 2 integers that are congruent to 4 modulo 14.

vivado [14]

Answer:

32, 46

Step-by-step explanation:

Remember, a is congruent to b modulo d if d divides a-b.

Now, the problem says that b=4 and d=14.

Let a=32. Observe that a-b=28 and $\frac{28}{14}=2$ , then 32 is congruent to 4 modulo 14.

Let a=46. Observe that a-b=46-4=42 and $\frac{42}{14}=3$ , then 46 is congruent to 4 modulo 14.

Many states are carefully considering steps that would help them collect sales taxes on items purchased through the Internet. Ho

prisoha [69]

Answer:

Step-by-step explanation:

Step 1

Divide your confidence interval by 2. In this case the confidence is 95% = 0.095, so 0.095/2 = 0.0475

Step 2

Use either a z-score table or a computer to find the closest z-score for 0.0475 and you will find this value is 1.96

Step 3

Divide the margin error by 2. In this case, the margin error is 2%. When dividing this figure by 2, we get 1% = 0.01

Step 4

Divide the number obtained in Step 2 by the number obtained in Step 3 and square it

1.96/0.01 = 196 and 196 squared is 38,416

Step 5

As we do not now a proportion of people that purchase on line, we must assume this value is 50% = 0.5. Square this number and you get 0.25

Step 6

Multiply the number obtained in Step 5 by the number obtained in Step 4, round it to the nearest integer and this is an appropriate size of the sample.

38,416*0.25 = 9,604
