Answer:

x=20

Step-by-step explanation:

2.5x+6=0.5x+46

subtract 0.5x from both sides

2x+6=46

subtract 6 from both sides

2x=40

divide both sides by 2

x=20

In the book Business Research Methods, Donald R. Cooper and C. William Emory (1995) discuss a manager who wishes to compare the
S_A_V [24]

Answer:

Null hypothesis is: U1 - U2 ≤ 0

Alternative hypothesis is U1 - U2 > 0

Step-by-step explanation:

The question involves a comparison of the two types of training given to the salespeople. The requirement is to set up the hypothesis that type A training leads to higher mean weakly sales compared to type B training.

Let U1 = mean sales by type A trainees

Let U2 = mean sales by type B trainees

Therefore, the null hypothesis (H0) is: U1 - U2 ≤ 0

This implies that type A training does not result in higher mean weekly sales than type B training.

The alternative hypothesis (H1) is: U1 - U2 > 0

This implies that type A training indeed results in higher mean weekly sales than type B training.

Given the figure what is the value of x show your work
grandymaker [24]

51 + 3x+5 = 107

Simplify the left side:

3x + 56 = 107

Subtract 56 from both sides:

3x = 51

Divide both sides by 3:

x = 51 / 3

x = 17

Angle F and the outside angle of 107, need to equal 180 degrees.

F - 180 - 107 = 73 degrees.

Simplify \frac{5}{3}x​3​​5​​x to \frac{5x}{3}​3​​5x​​

x-\frac{5x}{3}<3x−​3​​5x​​<3


2

 

Simplify x-\frac{5x}{3}x−​3​​5x​​ to -\frac{2x}{3}−​3​​2x​​

-\frac{2x}{3}<3−​3​​2x​​<3


3

 

Multiply both sides by 33

-2x<3\times 3−2x<3×3


4

 

Simplify 3\times 33×3 to 99

-2x<9−2x<9


5

 

Divide both sides by -2−2

x>-\frac{9}{2}x>−​2​​9​​

The sum of two consecutive odd integers is 28. What are the integers?
Fantom [35]
The correct option is B): "<span>Let x = 1st integer. Let x + 2 = 2nd integer.</span><span>"
Given that "The sum of two consecutive odd integers is 28."
 
Now the difference between two odd numbers is 2. So this means that one odd number has to be greater than the other by 2.

Let the smaller number be 'X' therefore the bigger number will be 'x+2' thus x + (x+2) = 28
 
therefore, x + x + 2 = 28 now we subtract "2" from both the sides
therefore, 2x = 26 now dividing throughout by 2 we get:

x = 13 therefore, x + 2 = 13+2
                                    = 15
 
therefore, the numbers are 13 AND 15</span>

Shuan rides his bike at a speed of 19 mph how far in miles is shuan travel in 25 minutes
irga5000 [103]

Answer:

7.92 miles   (aprox.)

Step-by-step explanation:

1 hour = 60 minutes

19mph = 19miles/hour = 19miles/60 minutes

Proportions:

19 miles ⇔ 60 minutes

W miles  ⇔ 25 minutes

W = 19*25/60

W = 7.92 miles     (aprox)
