Answer:
three hundred and eight five twenty sevenths
Answer:
x = 5 is the right answer.
Step-by-step explanation:
As we know sum of all angles in a triangle is 180°.Therefore in this question we will form an equation.
Sum of all the angles of a triangle = 180
91 + 10x - 4 +8x +3 = 180
90 + 18x = 180
18x + 90 - 90 = 180 - 90
18x = 90
x = 90÷18 = 5
Therefore x = 5 is the right answer.

Hello!
The study variable is:
X: number of passengers that rest or sleep during a flight.
The sample taken is n=9 passengers and the probability of success, that is finding a passenger that either rested or sept during the flight, is p=0.80.
I'll use the binomial tables to calculate each probability, these tables give the values of accumulated probability: P(X≤x)
a. P(6)= P(X=6)
To reach the value of selecting exactly 6 passengers you have to look for the probability accumulated until 6 and subtract the probability accumulated until the previous integer:
P(X=6)= P(X≤6)-P(X≤5)= 0.2618-0.0856= 0.1762
b. P(9)= P(X=9)
To know the probability of selecting exactly 9 passengers that either rested or slept you have to do the following:
P(X≤9) - P(X≤8)= 1 - 0.8657= 0.1343
c. P(X≥6)
To know what percentage of the probability distribution is above six, you have to subtract from the total probability -1- the cumulated probability until 6 but without including it:
P(X≥6)= 1 - P(X<6)= 1 - P(X≤5)= 1 - 0.0856= 0.9144
I hope it helps!

Anything to the power of 1 is still 1, because 
is simply 1 x 1 x 1 x 1 x 1 = 1 ect.
<h3>So this changes the equation to 1x = 2, which means that:</h3>
x = 2

This question is asking if the paint will be able to cover the area of the figure stated. (16 ft wide and 12 ft high i.e width and length.) Since one gallon covers 250 ft, using the area (A=w*l) formula, we can find the figure's area.
A= 16*12
A=192ft^2
Carolyn can cover the wall.
Hope this helps!
