Step-by-step explanation:

$\text{A geometric mean of}\ x\ \text{and}\ y:\\\\\sqrt{xy}\\\\\text{Let}\ x-\text{the number}.\\\\\text{Substitute:}\\\\\sqrt{17}=\sqrt{(7)(x)}\iff17=7x\qquad\text{divide both sides by 7}\\\\\dfrac{17}{7}=\dfrac{7x}{7}\to x=\dfrac{17}{7}$

The government taxes a manufacturer $1.00 per disposable camera. The manufacturer raises the wholesale prices an additional $2.0

Lady_Fox [76]

Answer:

A consumer pays $5 more per camera.

Step-by-step explanation:

Let the cost of manufacture of disposable camera in dollars be $=x$

Government taxes imposed on camera = $1.00 per camera

Cost of camera after taxes in dollars $=x+1$

Wholesale prices raised by manufacturer = $2.00 per camera

Wholesale price of camera in dollars per camera $=x+1+2=x+3$

Retail prices raised raised by retailer = $2.00 per camera

Retail price of camera in dollars per camera $=x+3+2=x+5$

Difference in prices of manufacture and retail price per camera in dollars

⇒ $x+5-x$

⇒ $5$

Thus, a consumer pays $5 more per camera.

Suppose that P(A|B)=0.2, P(A|B')=0.3, and P(B)=0.7. What is the P(A)? Round your answer to two decimal places (e.g. 98.76).

nata0808 [166]

Answer: $P(A) = 0.23$

Step-by-step explanation:

Given :

$P(A/B) = 0.2$

$P(A/B^{1})=0.3$

$P(B)= 0.7$

$P(A) = ?$

From rules of probability :

$P(A) = P(AnB) + P(A n B^{1})$ ........................... equation *

$P(A n B)$ can be written as $P(A/B)$ x $P(B)$

Also , $P(A/B^{1})$ can be written as $P(A/B^{1})$ x $P(B^{1})$

substituting into equation * , we have

$P(A) = P(A/B)$ $P(B) + P(A/B^{1})P(B^{1})$

since P(B) = 0.7, then $P(B^{1}) = 1 - P(B) = 0.3$

so , substituting each values , we have

$P(A) = (0.2)(0.7) + (0.3)(0.3)$

$P(A) = 0.14 + 0.09$

$P(A) = 0.23$
