Answer:

$\frac{d}{c}$

Step-by-step explanation:

The multiplicative inverse of a number n is $\frac{1}{n}$

The product of the number and its multiplicative inverse = 1

n × $\frac{1}{n}$ = 1

Thus the multiplicative inverse of $\frac{c}{d}$ is

$\frac{1}{\frac{c}{d} }$ = $\frac{d}{c}$

Answer:

95% Confidence interval: (31.32%,47.04%)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 148

Number of people who sleep for 8 hours or longer, x = 58

$\hat{p} = \dfrac{x}{n} = \dfrac{58}{148} = 0.3918$

95% Confidence interval:

$\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting the values, we get:

$0.3918\pm 1.96(\sqrt{\dfrac{0.3918(1-0.3918)}{148}})\\\\ = 0.3918\pm 0.0786\\\\=(0.3132,0.4704)=(31.32\%,47.04\%)$

(31.32%,47.04%) is the required 95% confidence interval.

Help me find the area of this circle

ch4aika [34]

The area would be approximately 153.94.

The area of a circle is pie multiplied by r^2.

So you have the radius, which is r. Plug in r. Technically you have two numbers because pie equals approximately 3.14.

A=3.14(7)^2

What is the solution to this equation x+ 3 2/3= 26

jenyasd209 [6]

Answer:

Exact form : x = 67/3

Decimal form : x = 22.33333333333...

Mixed Number form : x = 22 1/3

Step-by-step explanation: Solve for x by simplifying both sides of the equation, then isolating the variable.

I hope this helps you out. :)
