Answer:
Step-by-step explanation:
Given that despite a series of quality checks by a company that makes television sets, there is a probability of 0.07% that a newly purchased television set does not work properly.
Mean of X = np = 175
Var = np(1-p) = 174.8775
Std dev = 13.224
X is N(175, 13.224(
With continuity correction required prob
= P(X<200) = P(X<200.5)
= 0.973091
Using binomial
P(X<200) = 0.9659
F(x)=2(5/2)-x
y(0,2)
Is the intercept

A quadratic equation has the form<span>A<span>x2</span>+Bx+C=h(x)</span>is there anything in the problem that indicates the initial height of the ball before launch is zero?
The critical value is z=1.88.
We find this by first converting the percent confidence we want to a decimal: 94% = 94/100 = 0.94
We subtract that from 1 to find the alpha level:
1-0.94 = 0.06
Divide this by 2 (to find the area in each tail):
0.06/2 = 0.03
Subtract this from 1 again (because we want the area in the middle, not in each tail):
1 - 0.03 = 0.97
Using a z-table (http://www.z-table.com) we see that the closest to this in the table is at z = 1.88.
Answer:
dA(r) = 6.9 cm²
Step-by-step explanation:
Area of a rectangle is
A(r) = L * W (1)
Where L stands for length and W for width.
Taking differentials on both sides f equation (1)
dA(r) = W*dL + L*dW
As error in measurments are at most 0,1 cm ( in each side), then the maximum error in calculating the area is
dA(r) = 24* ( 0,1) (cm²) + 45*(0,1)(cm²) ⇒ dA(r) = 2.4 + 4.5 (cm²)
dA(r) = 6.9 cm²
