Point W
Step-by-step explanation:
Just trusssss me
You have 1/7 divided by 3. And you should know that you can multiply by the reciprocal. Put a 1 over the 3 to get 1/3.
1/7 x 1/3 = 1/21
Answer:
Value of 26.93 will be exceeded 85% of the time.
Step-by-step explanation:
We are given that a random variable is normally distributed with a mean of 25 and a standard deviation of 5.
Let X = a random variable
So, X ~ N()
The z score probability distribution is given by;
Z = ~ N(0,1)
where, = population mean
= standard deviation
Now, we have to find that value which will be exceeded 85% of the time, i.e.;
P(X > ) = 0.85
1 - P(X ) = 0.85
P(X ) = 0.15
P( ) = 0.15
P(Z ) = 0.15
Now, in the z table the critical value of whose less than area is 0.15 is given as 0.3853, i.e;
= 0.3853
= 25 + 1.9265 = 26.93
Therefore, value of 26.93 will be exceeded 85% of the time.
Answer:
C) 1/6y+1/6(y+12)-2
Step-by-step explanation:
Answer: Y-intercept is (0,-1/7) and the slope is -3/7
Step-by-step explanation:
State the slope and the y-intercept for the graph of each
equation y= -3/7x–1/7
To find the y-intercept,
you plug in 0 in for x for y= -3/7x–1/7
y=-3/7(0)-1/7
y=0-1/7
y=-1/7
The y-intercept is (0,-1/7)
To find the slope, you first check that the equation is in the form of y=mx+b
y= -3/7x–1/7 is in the from of y=mx +b.
The m is the slope
hence, in y= -3/7x–1/7 the slope is -3/7
