Hey there!

(-2)2 + (-42) + (18 - 23).

= -2(2) - 42 + 18 - 23

= -4 - 42 + 18 - 23

= -46 + 18 - 23

= -46 + (-5)

= -46 - 5

= -51

Therefore, your answer is: -51

Good luck on your assignment and enjoy your day!

lukranit [14]

Answer:

Mean = 55.2

Step-by-step explanation:

Given data set: 113, 14, 23, 12, 114

To find the mean of a data set, divide the sum of all data values by the total number of data values:

$\large \begin{aligned}\sf Mean & = \sf\dfrac{sum\:of\:all\:data\:values}{total\:number\:of\:data\:values} \\\\\implies \sf Mean & = \sf \dfrac{113 + 14 + 23 + 12 + 114}{5}\\\\& = \sf \dfrac{276}{5}\\\\& = \sf 55.2\end{aligned}$

During a catered lunch, an average of 4 cups of tea are poured per minute. The lunch will last 2 hours. How many gallons of tea

Liono4ka [1.6K]

Answer:

30 gallons

Step-by-step explanation:

step 1 right it out

2 hour is 120 mins and 4 cups are poured per min

step 2 Equation time

so your equation should be

4/1=x/120

step 3 solve it out

1 times 120 is 120 is 4 times 120 is 480

but that is not the answer 480 is the amount of CUPS that are used for 2 hrs

so all u have to do is now convert

step 4 convert

16 cups are in 1 gal. so divide 480 by 16 and get 30 gal

x=30 gallons

hoped it helped
