Data on the number of work days missed and the annual salary increase for a company’s employees show that, in general, employees

KengaRu [80]

Answer:

Step-by-step explanation:

Correlation describes how strongly pairs of given variablé are related. In this case, a detailed analysis that was carried out shows that the number of days missed by employees explains 60% of the variation in salary increases and also impressed upon this fact that employees who missed more days of work during the year received smaller raises than those who missed fewer days.

From the analysis, we can draw a conclusion that there is a correction between days missed and variation in salary increase and that this type of correction is a negative correlation where an increase in the number of days missed will lead to a decrease in the raises awarded to each employee.

How many pennies could you have if: When you break the pennies into groups of 2, you have 1 penny left over, AND when you break

zhenek [66]

Answer:

Step-by-step explanation:

"When you break the pennies into groups of 2, you have 1 penny left over"

You have an odd number of pennies.

"when you break the pennies into groups of 3, you have 1 penny left over"

The number of pennies is one more than a multiple of 3.

"when you break the pennies into groups of 5, you have 1 penny left over"

A number that is divisible by 5 ends in 0 or 5. You have one more penny than that, so the number will end in 1 or 6. We already know the number is odd, so it cannot end in 6. The number of pennies must end in 1.

"when you break the pennies into groups of 7, you have NO pennies left over"

The number is a multiple of 7.

We need a multiple of 7 that ends in 1.

7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, ...

You could have 91.

Mr Oneill bought cheese, turkey slices and wheat rolls for $55. The ratio of the amount of money spent on cheese to the amount o

astra-53 [7]

Answer:

Mr. O'neill buy 33 turkey slices.

Step-by-step explanation:

Firstly let us denote amount of money spent on Cheese by the symbol C.

amount of money spent on Turkey by the symbol T.

amount of money spent on Wheat by the symbol W.

Now we are the ratio of amount of money spent on cheese to the amount of money spent on turkey slices as 2:3 ;

We can represent this as $\frac{C}{T}$ = $\frac{2}{3}$

The ratio of the amount of money spent on cheese to the amount of money spent on wheat rolls is 6:5 ;

We can represent this as $\frac{C}{W}$ = $\frac{6}{5}$

Now we will make C also 6 in the first ratio to represent similarity in ratios i.e. $\frac{C}{T}$ = $\frac{2 * 3}{3 * 3}$ = $\frac{6}{9}$

So, the ratio of amount of money spent on cheese to the amount of money spent on turkey slices to the amount of money spent on wheat rolls is represented by 6 : 9 : 5.

To find the amount of money spent on turkey slices = $\frac{9}{6+9+5} * $55$ = $24.75

Since cost of each turkey slice cost = $ 0.75

Therefore, Cost of each turkey slice * Number of turkey slices = Total amount of money spent on turkey slices

$0.75 * Number of turkey slices = $24.75

Therefore, Number of turkey slices that Mr. O'neill buy = $24.75/$0.75

= 33 slices.
