Answer:

A) x=8 and angle ABC=115 degrees

Step-by-step explanation:

the lines are parallel, meaning the angles are congruent.

you can set up the equation (15x-5)=(10x+35) and simplify.

1. separate variable by subtracting 10x on both sides to get (5x-5)=(35)

2. add 5 on both sides to get 5x=40

3. divide both sides by 5 to get x=8

4. plug x=8 into original function (10x+35) to get (10(8)+35) which equals 115 degrees

Answer: 9 Apples

Step-by-step explanation:

Given the following :

Total number of bags = 12

Mean of the distribution(m) = 8

Number of apples (x):

6 - - - - 7 - - - - 8 - - - - 9 - - - - 10

Frequency (f) :

1 - - - - 4 - - - - 2 - - - - 3 - - - - 1

Therefore :

Let number of apples in the 12th bag = y

Frequency of 12th bag : (12 - 11) = 1

Mean of distribution(m) :

Sum of ( f * x) / sum of f

Sum of (f * x) = (6*1)+(7*4)+(8*2)+(9*3)+(10*1)+(y*1)

Sum of (f * x) = (6+28+16+27+10+y) = 87 + y

Sum of f = 12

From :

m = Sum of ( f * x) / sum of f

8 = (87 + y) / 12

87 + y = 12 * 8

87 + y = 96

y = 96 - 87

y = 9

Number of apples in 12th bag is 9 apples
