1) the form of the equation may be written as y = A(X - Xo)(X - X1)
Where Xo and X1 are the two roots of the equation.
2) We can fix the system of coordinates so that the vertex is in the middle of the gate => Xo = - 40 and X1 = +40
=> y = A (X + 40) (X - 40) = A (X^2 - 1600)
3) The height, at X = 0 is 25
=> A(0 - 1600) = 25
=> -1600A = 25 => A = -25 / 1600 = - 1/64
4) The equation is y = - [1/64] (X^2 - 1600)
5) You can present it in different equivalent forms.
Some of those other forms are:
1) - 64y = (x^2 - 1600)
2) x^2 = - 64y + 1600
3) X^2 = - 64 (y - 25)
Answer:
Step-by-step explanation:
2n+15>3
<span>The answer is: the least amount is 105.35 and the greatest amount is 105.44. If the number after the one you want to round is 5 or bigger, you need to round up the number. For instance, 105.35 is rounded to 105.4 which is equal to 105.40. If the number after the one you want to round is smaller than 5, you need to round down the number. For instance, 105.44 is rounded to 105.4 which is equal to 105.40.</span>
Answer:
a.
b-Check illustration below
c.(-0.0517,0.0177
Step-by-step explanation:
a.let 
denote processes 1 & 2.
For 
: T1=10,n1=200
For 
:T2=20,n2=300
Therefore
b. To test for hypothesis:-
i.
ii.For a two sample Proportion test
iii. for 
(0.5 alpha IS 0.025),
reject 
if
iv. Do not reject . The noncomforting proportions are not significantly different as calculated below:
z=-0.78
c.
for the p1-p2 is given as:
=(-0.0517,+0.0177)
*CI contains o, which implies that proportions are NOT significantly different.
Answer:
3 hours 20 minutes
Step-by-step explanation:
Together, the workers can assemble 9 + 6 = 15 products per hour. So the assembly of 50 products will take ...
(50 products)/(15 products/hour) = 50/15 hours = 3 1/3 hours
The two workers can assemble 50 products in 3 1/3 hours.
