Step-by-step explanation:
A=s*s
A=s^2
52=s^2
s=√52
s=7.2 one side of the square
s*4 to get the four sides
7.2*4=28.8 cm length of the first piece
40-28.8=11.2cm length of the second piece
Answer:
Probability = 0.0228
Step-by-step explanation:
Let X be a random variable which is a measure of the time to get a passenger on board.
Mean(u) = 22.5mins
Standard deviation (s) = 5.25mins
X = 33mins
From Pr(X>33), starting from Pr(X = 33)
For normal distribution, Z = 7(X - u) /s
Z= (33 -22.5) /5.25
= 10.5/5.25
= 2
From the normal distribution table, 2 = 0.4772
Recall that
If Z is positive,
Pr(x>a) = 0.5 - table value
Pr(x<a) = 0.5 + table value
Therefore;
Pr(X>33) = 0.5 - 04772
= 0.0228
Answer:
Step-by-step explanation:
According to Frank's data, the number of bacteria grows by 20 percent every hour and it starts with 150 cells.
Therefore, the function to predict the population of bacteria is given by
{Where h is the number of hours passed}
⇒
Therefore, Frank's function that he created to predict the population of bacteria is flawed. (Answer)
Answer:
The length of the missing side is: x = 15
Thus, option A) is the correct option.
Step-by-step explanation:
Let 'x' be the missing sides.
From the given triangle, it is clear that the segment cuts the sides into proportional ratios such 9 : 12 and x : 20 respectively.
Therefore,
9 : 12 = x : 20
9/12 = x/20
cross multiplication
12 × x = 20 × 9
12x = 180
divide both sides by 12
12x/12 = 180/12
x = 15
Therefore, the length of the missing side is: x = 15
Thus, option A) is the correct option.
