Answer:
x = 7
Step-by-step explanation:
the 2 is doubled so the 3.5 has to be doubled as well
The correct answers would be a b and 2 because I don’t know this is a test to be honestly
Answer:
Central angle = 0.0003π
Step-by-step explanation:
Radius of circle = r = 555 in = 14.097 m
Arc length = s = 30 in = 0.762 m
Using formula
Converting θ to radians
Answer:
So in range "-35.6108 to 39.73"; 50% data set can be found
ux = 37.6704 unites
Step-by-step explanation:
Step One: State the given parameters
From the question we are given that
mean Ц =2.06 unites
Standard deviation б is = 55.85 unites
Probability density → Normal
Let assume that it is symmetrically distributed about the mean
Step Two: Determine the range of the values
Our goal is to determine the range of values in which 50% of the data set should be found . Assuming that the range is from 
to 
and between these these we found 50% data set Hence from 0 up to we found 25% and up to we found 75% of the data set therefore z value corresponding to is - 0.6745 and the the z value corresponding to is +0.6745 (Refer to the z-table for normal distribution) as shown o the diagram on the first uploaded image
The formula for z is
z = 
for ,z = - 0.6745 ,substituting into the formula
=> -37.67 = -2.06
=> = -35.6108 unites
for , z = 0.6745 , substituting into the formula
=> 37.67 = -2.06
=> = 39.73 units
So in range "-35.6108 to 39.73"; 50% data set can be found
ux = (39.73 - (-35.73) )/2
= 37.6704 unites
The unit rate that corresponds to the proportional relationship shown in the given graph above is: 4/3 cm/s.
<h3>How to Find the Unit Rate of a Proportional Graph?</h3>
The unit rate of a proportional graph is determined using the formula below:
k = y/x, where x and y are coordinates of any point on the line.
Thus, to find the unit rate of a proportional graph, pick the coordinates of any point on the line and find k = y/x.
From the given graph, let's pick the indicated point on the line having the coordinates, (12,16). Find k:
Unit rate (k) = 16/12
Simplify
Unit rate (k) = 4/3
Therefore, the unit rate that corresponds to the proportional relationship shown in the given graph above is: 4/3 cm/s.
