b. Exactly 6 of the calls involve a fax message?
c. At least 6 of the calls involve a fax message?
d. More than 6 of the calls involve a fax message?
e. What is the expected number of calls among the 25 that involve a fax message?
f. What is the standard deviation of the number among the 25 calls that involve a fax message?
g. What is the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations?

OLEGan [10]

Step-by-step explanation:

(2$+1.5&)+0.9$X=20$

3.5$+0.9$X=20$

0.9$x=20$-3.5$

x=16.5$/.9$

x=18.333

so he can travel 18.333miles.

first we need to add the two separated cause of 1.5 Dollar in $2 tip which give us 3.5 dollar that is to be subtracted from the $20 you have. then the money that is left in your pocket is 16.5 dollar s this will be deducted 0.9 for every mile so dividing 16.5 by 0.9 gives 18.333.

lidiya [134]

Step-by-step explanation:

Step-by-step explanation:

Given the table:

Month              f(x) = Number of imports    g(x) = Number of exports

January (1)                3                                                1

February (2)             4                                                3

March (3)                  5                                                5

April (4)                     6                                                7

From the table, it is clear that:

Number of imports = number of month + 2

so

also

Number of exports  = 2(number of month) + 1

so

Therefore, the number of imports equals the number of months plus one. i.e., which is a linear function.

If we compare it with the slope-intercept form of the line

Then,

slope = m = 1

y-intercept = 2

Also number of exports equals is also a linear function.

i.e.  

Here,

slope = m = 2

y-intercept = -1

Need help plz <br> How do you do this?
gavmur [86]

Answer:

See description below.

Step-by-step explanation:

A distance -time graph of Maria's journey would look like a very steep line with slope 100 meters/1 minute until minute 4. At minute 4, Maria stopped to talk so it would like a horizontal flat line at that same distance for 3 minutes. This means at minute 7, Maria began walking again. From minute 7 on would be a positive line heading up with a slope of 75 meters/ 1 minute.
