4 0

Answer:

126

Step-by-step explanation:

Row 1: 30+0*4

Row 2: 30+1*4

Row 3: 30+2*4

...

The list goes on. Do you see a pattern here? If we call the row number as r, the formula is 30+(r-1)*4. In the 25th row, the r is 25. So in the formula, it is 30+(25-1)*4=30+24*4=126.

I hope that helped.

Math question please help!!!
mars1129 [50]

Answer:

Option B. 75

Step-by-step explanation:

we know that

<u>A negative correlation</u> or inverse correlation is a relationship between two variables such that as the value of one variable increases, the other decreases

we know that

For L1=150, K1=7

so

For K2=14, L2=?

we have that

L1*K1=L2*k2

substitute the values

150*7=L2*14

L2=150*7/14

L2=75
