Answer:
One sample t test
Step-by-step explanation:
A one proportion sample t test is employed when we intend to test the sample mean of a certain sample against a particular or specified population property . In the scenario above, we could use the information given to obtain the one sample proportion test statistic by using the formular :
Test statistic = (xbar - μ) ÷ (σ/sqrt(n))
Where, xbar = sample mean ;
μ = population mean
σ = population standard deviation
n = sample size
Using the test statistic, we can then obtain the Pvalue and compare to the specified α - level
Answer: Okay so find the area of the big shape.7x15=105Now find the area of the small one which is:5x13=65And now all you have to do is take away the area of the small box away from the big box. So...105-65=40... But remember to put in the right form which is cm but since we found the area of 2d shape it's going to be cm2. So.... 40cm2

Answer:
The equation of the Parallel line passes through the point (-1,4) is
y = -5 x -1
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given the equation of the line y = -5 x + 2
Given point (-1 , 4 )
The equation of the parallel line of a given line is 5x + y +k=0 ...(i)
The equation (i) passes through the point (-1,4)
5(-1)+4+k=0
-5 +4 +k =0
-1 + k = 0
k = 1
<em>The equation of the Parallel line passes through the point (-1,4) is </em>
<em> y = -5 x -1</em>
Answer:
The radius of the gear is, 0.286624204 m
Step-by-step explanation:
A gear is driven by a chain that travels 90 m/min. If it makes 50 revolutions per minute. then find the radius of the gear
let angular velocity be 
, velocity be v and radius be r.
Given:
Angular velocity 
=50 revolutions per minute
1 revolution = 
radian
50 revolution= 
radian
therefore, 
radian per minute
and velocity(v) = 90 meter per minute
Use formula: Velocity(v)= radius(r) 
angular velocity
then, we write above formula as : 
Substitute the value of v and to solve for r: the constant value of pi i.e, 
[as radian is unit less]
If you mean cuboid then no and if you mean rectangle but sides not faces then yes
