Well, if I remember correctly, Zeroes just mean the x values. But I can't tell where your equation breaks apart; like which parts are which parts of the equation

The average speed of a car driving down freeway is 70mph with a standard deviation of 5mph. Thid speed is normally distributed.
ikadub [295]

Answer:

0.081,0.2621,0.645,0.919

Step-by-step explanation:

Let X be the average speed of a car driving down freeway

Given that X is normal with mean as 70mph with a standard deviation of 5mph.

To convert to Z score we do

Z =\frac{x-70}{5}

a)  the probability that a randomly selected car is driving more than 77mph

=P(X>77)\\=P(Z>1.4)\\=0.081

b) probability that a randomly selected car is driving between 65 and 69 mph

= P(-1

c) the probability that a randonly selected car is driving between 67 and 77mph

=P(-0.6

d) the probability that a randomly selected car is driving less than 77mph

=P(Z

A candy store sells 8-pound bags of mixed hazelnuts and cashews. If c pounds of cashews are in a bag, the price p of the bag can
DochEvi [55]

A candy store sells 8 pound bags of mixed almonds and cashews. If c pounds of cashews are in a bag,...

c=1 was already given as described. The store sells pound bags.

The rest of the description and question seem not to match. Maybe each bag contains 8 pounds of the two nuts. Eight pounds and some of this is of cashews. Now, c is how many pounds of cashews in one bag.

-

 

p=2.59%2Ac%2B1.72%288-c%29

You want to know the quantity of cashews if p=18.11 dollars per bag.

2.59c%2B1.72%2A8-1.72c=p

2.59c-1.72c=p-1.72%2A8

%282.59-1.72%29c=p-1.72%2A8

0.87c=p-13.76

Is 5/6 closer to 1, 1/2, or 2 and why?
velikii [3]
1 because 5/6 is almost a whole. It can't be 1/2 because it would have been 3/6. And it's not 2 because it should have been an improper faction
