I think it could be B..not sure though. Please help!

Answers

Taking the slope about different points, we have
m_(1) = ( y_(2)- y_(1) )/(x_(2)- x_(1)) = (100-63)/(18-12) = (37)/(6) =6 (1)/(6) \n m_(2) = ( y_(2)- y_(1) )/(x_(2)- x_(1)) = (30-88)/(8-16) = (-58)/(-8) =7 (1)/(4)
The slopes are positive but are not equal, which means that that the association is positive non linear association.

Several people were polled regarding their favorite type of dessert. They were asked to choose one of the following: ice cream, cake, candy, or cookies. 10% cookies, 30% candy, 25% cake, 35% ice cream. If forty people were questioned, how many of them said they prefer ice cream

Answers

So notice the total number of people is 40, we need to find the number that likes ice cream 

so simply convert the 35% into a decimal (0.35) then multiply it by 40 

40 x .35 = 14 people
well first you would create a percent pororpotion

Answers

1).  To multiply with like bases, add the exponents ===>  5² x 5⁵ = 5⁷

2).  Same rule.  e² x e⁷ = e⁹

3).  Same rule, but make sure to start with like bases.

2a⁵ x 6a = (2 x 6) (a⁵ x a¹) = 12 a⁶

4).  Same rule, but make sure to start with like bases.

4x² (-5)x⁶ = (4) (-5) (x² x⁶) = -20x⁸

5).  To divide with like bases, subtract the denominator (divisor) exponent
from the numerator (dividend) exponent. ===> 7⁹ / 7³ = 7⁶

6).  Same rule.    v¹⁴ / v⁶ = v⁸

7).  Same rule, but make sure to start with like bases.

15w⁷ / 5w² = (15/5) (w⁷/w²) = 3 w⁵

8).  Same rule, but make sure to start with like bases.

10 m⁸ / 2m = (10/2) (m⁸ / m¹) = 5m⁷

9).  Same rules.  Add exponents to multiply, subtract them to divide.

( 2⁵ x 3⁷ x 4³ ) / (2¹ x 3⁵ x 4) = (2⁵ / 2¹) x (3⁷ / 3⁵) x (4³ / 4¹) = 2⁴ x 3² x 4²

10).  (4¹⁵) x (-5)⁶ / (4¹² x (-5)⁴ ) = (4¹⁵/4¹²) x [ (-5)⁶/(-5)⁴ ] = 4³ x (-5)² = 4³ x 5²

11).  (6⁷ x 7⁶ x 8⁵) / (6⁵ x 7⁵ x 8⁴) = (6⁷ / 6⁵) x (7⁶ / 7⁵) x (8⁵ / 8⁴)
       You can finish it from here, you Crazy Unicorn you.

12).  [ (-3)⁶ x 10⁵ ] / [ (-3)⁴ x 10³ ]   =  [ (-3)⁶ / (-3)⁴ ] x (10⁵/10³)  
        The last step is yours.  Take it !
