Answer:
4)There is a 4% chance that there is no relationship between temperature and revenue.
Step-by-step explanation:
Given that the owner of an ice cream shop wants to determine whether there is a relationship between ice cream sales and temperature. The owner collects data on temperature and sales for a random sample of 30 days and runs a regression to determine if there is a relationship between temperature (in degrees) and ice cream sales
A) The p value is the probability of rejecting null hypothesis when it is true.
In this case null hypothesis would have been there is no relationship between temperature and Sales.
The probability of concluding that there is relationship between temperature and sales when there is actually no real realtionship is only 0.04.
4)There is a 4% chance that there is no relationship between temperature and revenue.
is right answer
Coolio
alright, so the disatnce formula is
solve for y in the equation given on top
2x+y-10=0
y=10-2x
ok
so (x1,y1)=(0,0), the first point
(x2,y2)=(x,10-2x)
so subsitute to get
find the miniumum
we only need to minimize what is under the square root so
take the derivitive of 5x²-40x+100
that is 10x-40
it is 0 at x=4
when x<4, the derivitive is negative
when x>4, the derivitive is positve
goes from negative to positive
so it is a minimum
at x=4
find y
y=10-2x
y=10-2(4)
y=10-8
y=2
(4,2)
find min distance
the point, P, is (4,2) and the minimum distance is 2√5
F ( x ) = 7 x + 2
y = 7 x + 2
- 7 x = - y + 2 /*(-1)
7 x = y - 2 / : 7
x = y/7 - 2/7 = ( y - 2 ) / 7
The inverse of the function is:
f^(-1) ( x ) = ( x - 2 ) /7
Answer:
(3,-2), units
Step-by-step explanation:
the correct question is:
Write the ordered pair that represents yz. Then find the magnitude of yz . y(-2,5),z(1,3)
SOLUTION:
points given are y(-2,5) and z(1,3)
so, the ordered pair is (3,-2)
next is to find the magnitude:
units
Answer:
make 360×each number given/15 students to start drawing
360×7/15=168°
360×5/15=120°
360×2/15=48°
360×1/15=24°
now draw each one from the radius give to the clockwise
if you don't know what's clockwise direction, see it from your house or tell anybody in your home to tell you where is clockwise
after you finish drawing, label each section by writing the names on the correct sections ( you can write in or out of the circle)
