What is the difference between

ankoles [38]

we are given

$\sum _{n=0}^4\:\left(1+3n\right)$

we can find it's sum

$\sum _{n=0}^4\:\left(1+3n\right)=(1+3*0)+(1+3*1)+(1+3*2)+(1+3*3)+(1+3*4)$

$\sum _{n=0}^4\:\left(1+3n\right)=35$

now, we can find second sum

$\sum _{i=2}^6\:\left(3i-5\right)=(3*2-5)+(3*3-5)+(3*4-5)+(3*5-5) + (3*6-5)$

$\sum _{i=2}^6\:\left(3i-5\right)=35$

so, we can see that

both sums are 35

so, their difference will be 0

kiruha [24]

Answer:

$Average = 38$

Step-by-step explanation:

Given

The attached histogram

Required

The average work hours by 20 salespeople

First, we get the total hours worked as follows:

$Hours = 3 * 30 + 5 * 34 + 9 * 40 + 2 * 45 + 1 * 50$

$Hours = 760$

Divide by number of salespeople

$Average = Hours/n$

$Average = 760/20$

$Average = 38$

Use the diagram to solve x and y

Maru [420]

Answer:

x = 54°

y = 144°

Step-by-step explanation:

x° + 36° = 90° (complementary angles)

Subtract 36° from each side of the equation

x° = 90 - 36°

x = 54°

y° + 36° = 180° (angles on a straight line/supplementary angles)

Subtract 36° from each side

y° = 180° - 36°

y = 144°
