ICE Princess25 [194]
Hopefully this is the correct answer! but your expression would be:  y=40x+30
and if he drove for 5hrs then you would plug in 5 for your x value so it would be y=40*5+30 and 40*5 is 200.(the star means multiplying) then add 30 to get a total of $230
so the expression is:  y=40x+30
and if he drove for 5hrs then he sould make a total of: $230
hopefully that helped and was the right answer  :)

A random sample is to be selected from a population that has a proportion of successes p=.60. When n=400, what is the probabilit
Nata [24]

Answer:

0.45134

Step-by-step explanation:

Given that :

p = 0.6

n = 400

Probability that sample. Proportion falls between 0.59 and 0.62

Using Normal approximation :

Mean (m) = n * p = 400 * 0.6 = 240

Standard deviation (s) = sqrt(pq/n)

q = 1 - p = 1 - 0.6 = 0.4

s = sqrt((0.6 * 0.4) / 400) = 0.0244948

P(0.59 < p < 0.62) :

(x - m) / s

P((0.59 - 0.6) / 0.0244948) < p < P((0.62 - 0.6) / 0.0244948)

P(Z < −0.408249) < p < P(Z < 0.8164998)

Using the Z probability calculator :

0.79289 - 0.34155 = 0.45134

What is 4 over 15 plus negative 7 over 45
IgorLugansk [536]

Answer:

If what I think youre saying is correct, then it should be 1/9

Step-by-step explanation:

4/15 + (-7/45)

Multiply both numerator and denominator of 4/15 by 3 so that the denominator becomes 45 to match the other fraction.

12/45 + (-7/45)

As the fraction on the right side is negative, it is taken away from the left fraction, hence:

(12 - 7)/45

Therefore, with simple subtraction,

5/45

Simplify to 1/9
