Answer:

h(x)=log2(x)

Step-by-step explanation:

The find the inverse of an invertible function y=f(x),

swap y and x and solve for y.

We have h(x)=y=2x.

Swapping x and y gives x=2y.
We now wish to solve for y.Take the log with base 2 of both sides of the equation to free the y variable.

x=2ylog2(x)=log2(2y)=yThus, y=h(x)=log2(x).
See that we used the fact that logn(nx)=x

Answer:

If I understand correctly, your trying to find the inverse function of:

h(x)= $\frac{2}{x}$ + 1, If so...

The Acme Company manufactures widgets. The distribution of widget weights is bell-shaped. The widget weights have a mean of 60 o

Gala2k [10]

Answer:

Step-by-step explanation:

Given that the Acme Company manufactures widgets, which have a mean of 60 ounces and a standard deviation of 7 ounces

We know that 95% of the area lie between -2 and 2 std deviations from the mean.

i.e. Probability for lying in the middle of 95%

Z score $(60+7(-2), 60+7(2))\\=(46, 74)$

Between 46 and 74 oz.

b) Between 12 and 57

convert into Z score

$(\frac{12-60}{7}$

P(-6.86<z<-0.43)

=0.5-0.1664=0.3336

c) X<30 gives Z<-4.83

i.e. P(X<30) =0.00

Which of the following is another way to express the equation 8 - (-) = 43?

Olin [163]

Question:

Which of the following is another way to express the equation 8 - (-d) = 43?

A.8-d=43

B.-d+8=43

C.-8+d=43

D.8+d=43

Answer:

8 + d = 43 is another way to express the given equation

Solution:

Consider the given equation

$8 - (-d) = 43$

We have to find the another way to express the above equation

We know that,

We we multiply negative sign number by another negative sign number, then the result is positive sign number

Therefore from given,

$-(-d) = -1 \times -d = d$

Thus the given equation becomes,

8 + d = 43

Thus option D is correct
