Answer:
0.05
Step-by-step explanation:
We can correctly state that the total sample space= 100 students
40% of 100 students exercise regularly
The probability that 5 students
Picked at random exercise regularly is
Pr(5) = 5/100= 1/20
Pr(5)= 0.05
Answer:
D
Step-by-step explanation:
We have the 2 equations
1- ) 5x-8y=6
2-) -6x-3y=18
multiplying the first equation by 3 and the second equation by 8 then subtracting
1-) 15x-24y=18
2-) -48x-24y=144
-48x-24y=144
(-) 15x-24y=18
-------------------------------------
-63x = 126
x=-2
substituting in equation 1
5(-2)-8y=6
-10-8y=6
-8y=16
y=-2
the soultion is (-2,-2)
Domain = x<18000(You cant og a negative number)
Am I actually supposed to graph it? enter the equation on desmos.com
It takes longer to make the same altitudinal gain
t=50log(18000/(18000-4000))=50log(18000/14000)=5.457
The answer is 94
