Alright, so the area of one paper is 297mm*420mm=124740mm^2. Multiplying that by 6 due to 6 sheets, we get 748440mm^2. Converting mm^2 to m^2, since we know that 1000mm=1m, we simply do (1m/1000m)^2=1m^2/1,000,000mm^2. Our equation is now
748440mm^2*1m^2/1,000,000mm^2=0.748440m^2 by crossing out the millimeters. Lastly, since it's 80g/1m^2, we multiply our number by that to get 59.8752g

What is the probability a day in the 70s is a Monday?
Degger [83]

Answer:

a) Probability of a day with temperature in the 70s = 0%

b) The set of the intersection of Tuesdays and days with temperature in the 80s is an empty or null set.

c) Probability an observation picked at random is both a Sunday and more than 90 degrees

= 0.10 = 10%

Step-by-step explanation:

The table of data for this question was obtained online and attached to this solution

Note that the probability of an event is defined as the number of elements in that event divided by the Total number of elements in the sample space.

a) What is the probability a day in the 70s is a Monday?

Of the days with temperature in the 70s (only one day, which is a Sunday), none of them are Mondays, hence, the probability of a day with temperature in the 70s being a Monday is 0%.

b) Which set forms the intersection of Tuesdays in the 80s?

Acvording to the data available, the set of Tuesdays with temperatures in the 80s is an empty set. Hence, this set is a null set.

c) What is the probability an observation picked at random is both a Sunday and more than 90 degrees?

The number of Sundays with temperature more than 90 degrees = 3

The total number of observations available = 30

Probability an observation picked at random is both a Sunday and more than 90 degrees = (3/30) = 0.10 = 10%

Hope this Helps!!!

How many pizzas does a restaurant make each night if 25% of the total is equal to 90 pizzas?
TEA [102]
20% of 90 pizzas is 22.5 pizzas
And since you can’t just buy half a pizza it would have to be 23 pizzas :)

Help please ASAP!!
Fittoniya [83]

Answer:

\displaystyle 702

Step-by-step explanation:

we are given a exponential function

\displaystyle f(x) =  {3}^{x + 1}  - 22

where x represents the number and f(x) represents the amount

we are also given that when x is 3 then f(x) is 59 likewise when x is 6 then f(x) is 2165

to figure out the average rate of change between 3 and 6 we can consider the average rate of change formula given by

\displaystyle m =  \frac{ f(x)_ {2} -  f(x)_{1} }{ x_{2} -  x_{1} }

substitute what we have:

\displaystyle m =  \frac{ 2165 -  59 }{6 - 3 }

simplify substitution:

\displaystyle m =  \frac{2106 }{3 }

simplify division:

\displaystyle m =  702

hence, the average rate of change between 3 and 6 is <u>7</u><u>0</u><u>2</u>
