If you’re asking to solve y=-x+5 it would be x=5
i’m sorry if you was asking something else
The number 645,300 is is already in the expanded form. I think what you mean is in specific notation, because in this form, we make use of exponents. To convert this, simply move the decimal place to the left until before you get to the last digit. The number of places moved is equivalent to the exponents, and the + sign is for movement to the right, and the - sign is for the movement to the left. Thus, the answer would be 6.453×10⁻⁵.
It is given in the question that, PA is a radius and AB is the tangent segment .
And in a circle, radius and tangent are always perpendicular, it means they form 90 degree with each other . Or angle PAB is a right angle .
And we cant say anything about the length s of PA and AB, neither of PA and PB.
So out of the four options, correct option is the third option .
Answer:
There is no significant evidence to conclude that the mean waiting time is less than 3.8 minutes
Step-by-step explanation:
H0 : μ = 3.8
H1 : μ < 3.8
Test statistic :
(x - μ) ÷ s/sqrt(n)
(3.7 - 3.8) ÷ 0.6/sqrt(60)
Test statistic = - 1.29
The Pvalue from test statistic :
P(z < -1.29) = 0.0985
Reject Null if
Pvalue < α
0.0986 > 0.01 ; Hence, we fail to reject the null ;
There is no significant evidence to conclude that the mean waiting time is less than 3.8 minutes
251/50 or mixed number is 5 1/50
