The answer would be 4. this is because the data is inconsistent, and they would just find more data of previous users, because this adds more consensus. if that was wrong ( which is unlikely) it is 1, because it is checking the interests of common products. i pick tis because it has a consensus, similar to the fourth answer. good luck! hope this helped!

Will, Mike, and Sue went to dinner. Will paid 1/3 of the dinner bill. Micah and Sue paid in the ratio 2:3. If Sue paid $6 more t
raketka [301]
Let's call their parts w,m and s

if will paid 1/3, then m+s=2w (they paid 2/3, which is twice as much as will did)

Now, we know that:
Micah and Sue paid in the ratio 2:3.
this means the 3m=2s

and m=2/3s

Again:
m+s=2w

and we substitute m:
2/3s+s=2w
5/3s=2w// multiply both sides by 3
5s=6w

we also know that s=w+6 (from the last sentence) so we substitute:

5(w+6)=6w
5w+30=6w
30=w

so, Will paid 30, Sue paid 36 (six more than him), Mike paid 24 (24:36 is the same ratio as 2:3, you can check this by dividing both 24 and 36 by 12: you have 2 and 3)

and the total was 30+36+24=90.

Answer:

B) 63°

Step-by-step explanation:

<u>Step 1:</u> find the angle beside x (inside the pentagon)

<em>*A pentagon has a total of 540°</em>

119 + 100 + 116 + 88 = 423

540 - 423 = 117

<u>Step 2:</u> x is a supplementary angle, which means it's angle adds up to 180°

Since we know the other angle is 117°, we just subtract that from 180

180 - 117 = 63

x = 63

Which function is a horizontal compression of its parent function f(x)=x^7 by a factor of 4
evablogger [386]

Answer:

r(x)=(4x)^7


Step-by-step explanation:

  • For a horizontal compression, we multiply whole numbers greater than 1 in front of x of the given function.
  • For horizontal expansion, we multiply by the reciprocal of the number for horizontal compression, in front of x of the function.

For example,

If we wanted to <u>horizontally compress</u> y=x^2, we would multiply by 4 to get y=(4x)^2, and

if we wante to <u>horizontally expand</u> y=x^2, we would multiply by \frac{1}{4} to get y=(\frac{1}{4}x)^2


Since this question asks for horizontal compression, we multiply the x of the function by 4. So the function we need is f(x)=(4x)^7. The second choice is correct.
