If Y co-ordinate of a point is zero then this point always lies

alexandr402 [8]

Answer:

on the x-axis

Step-by-step explanation:

(assuming the point is on a rectangular coordinate plane) The y-coordinate determines where a point is "vertically". The x-axis is equal to y=0, so if the y-coordinate of a point is 0, i.e. (x,0), the point always lies on the x-axis.

The startup division made 80% of 1/2 of the established division. The startup division’s growth was 1/3 greater than the establi

Gnesinka [82]

Answer:

Step-by-step explanation:

First, let's create variables:

s = startup division

e = established divisioN

The startup division made 80% of 1/2 of the established division.

Let's take a look at what the above statement means: Making 80% of 1/2 means...

0.8 of 1/2 = 0.8*0.5 = 0.4 --> s = 0.4e.

Next: The startup division’s growth was 1/3 greater than the established division’s.

Seems like this is additional information is not needed.

If the divisions made 280,000 combined, how much did the startup division make?

s + e = 280,000 --> s = 280,000 - e, then we can substitude s = 0.4e for s -->

280,000 - e = 0.4e --> 1.4e = 280,000 --> e = 200,000.

This means that s = 80,000.

A ski gondola carries skiers to the top of a mountain. assume that weights of skiers are normally distributed with a mean of 199

Allushta [10]

A) maximum mean weight of passengers = load limit ÷ number of passengers

maximum mean weight of passengers = 3750 ÷ 25 = 150lb

B) First, find the z-score:
z = (value - mean) / stdev
 = (150 - 199) / 41
 = -1.20

We need to find P(z > -1.20) = 1 - P(z < -1.20)

Now, look at a standard normal table to find P(z < -1.20) = 0.11507, therefore:
P(z > -1.20) = 1 - 0.11507 = 0.8849

Hence, the probability that the mean weight of 25 randomly selected skiers exceeds 150lb is about 88.5% 

C) With only 20 passengers, the new maximum mean weight of passengers = 3750 ÷ 20 = 187.5lb

Let's repeat the steps of point B)

z = (187.5 - 199) / 41
 = -0.29

P(z > -0.29) = 1 - P(z < -0.29) = 1 - 0.3859 = 0.6141

Hence, the probability that the mean weight of 20 randomly selected skiers exceeds 187.5lb is about 61.4%

D) The mean weight of skiers is 199lb, therefore:
number of passengers = load limit ÷ mean weight of passengers
 = 3750 ÷ 199
 = 18.8
The new capacity of 20 skiers is safer than 25 skiers, but we cannot consider it safe enough, since the maximum capacity should be of 18 skiers.

mrs_skeptik [129]

Answer:

Part A: Suzanne bakes 350 in 5 hours and cole bakes 400 in 8 hours. Part B: cole can bake more then suzanne but Suzanne has more time to bake more, so i think suzanne bakes at a faster rate then cole
