Answer:
n = - 4
Step-by-step explanation:
note that 625 = , then
=
=
Since the bases on both sides are equal, both 5 then equate the exponents
n = - 4

Answer:
.
Step-by-step explanation:
The question requires that the equation should be in the slope-intercept form . The
and
in this equation are constants. In particular:
would represent the slope of this line (also known as the gradient of this line,) whereas
would be the
-intercept of this line.
The question states that the slope of this line is . Therefore,
. Thus, the equation for this line should be in the form
.
The value of constant could be found using the other piece of information: the point
is in this line. In other words, the solution
should satisfy the equation
.
Substitute into the equation
and solve for
:
.
.
.
Hence, would be the slope-intercept form of the equation of this line.
Answer:
<h2>The probability is 58 %.</h2>Step-by-step explanation:
This problem belong to a normal distribution probability.
Mean = 63.6
Standard Deviation = 2.5.
We have to find the probability of a height greater than 63.0.
Due to the normal probability, we need to find the Z score first:
; where x is the height, u is the mean, and o is the standard deviation.
Once we have our Z score, we find the probability with the z-table (attached). So, for a z score of -0.24 we have a probability of 0.42.
But, the problem is asking for height greater than 63.0, this mean that we have to subtract 0.42 from 1, giving as result 0.58, which means a 58% of probability,
