3. ** Over the course of July, the high temperatures of 6 random days were collected. The data is 2 shown below. 84°F 92°F 79°F

Tresset [83]

Given data:

The given table.

The expression for the average temperature is,

$\begin{gathered} 86^{\circ}F=\frac{84^{\circ}F+92^{\circ}F+79^{\circ}F+x+82^{\circ}F+93^{\circ}F}{6} \\ 516^{\circ}F=430^{\circ}F+x \\ x=86^{\circ}F \end{gathered}$

Thus, the value of x is 86 degree Fahrenheit.

Suppose that P(A) = 0.25 and P(B) = 0.40 . If P(A|B)=0.20 , what is P(B|A) ?

Ket [755]

Answer:

0.32

Step-by-step explanation:

<u>Use of formula:</u>

P(A and B) = P(A)*P(B|A) and
P(A and B) = P(B)*P(A|B)

<u>According to above and based on given:</u>

P(A)P(B|A) = P(B)P(A|B)
P(B|A) = P(A|B)*P(B)/P(A)
P(B|A) = 0.20*0.40/0.25 = 0.32

What ratios that are equivalent to 4 to 7.

expeople1 [14]

4 to 7 = 4/7

5/8 is not.

12/20 = 6/10 = 3/5 . It is not equivalent.

8:14 = 4 : 7 . It is equivalent

5 to 10 = 1 to 2. It is not.

16/28 = 8/14 = 4/7. It is equivalent.

9 to 16 = 9 to 16. It is not equivalent.

So only 8:14 and 16/28 are equivalent to 4 to 7.
