Answer:

8 1/2 liters

Step-by-step explanation:

In the morning the cow produced 2 3/5 liters of milk.

In the evening, the cow produced 3 3/10 more than in the morning; this means to find the total amount produced in the evening we add

2 3/5 + 3 3/10

To add these, find a common denominator; the first thing 5 and 10 will both go into is 10.  It takes two 5's to make 10; this means we use two 3's on the numerator, which gives us 2 6/10.

The second fraction is already over 10, so we do not need to change it.

2 6/10 + 3 3/10

Add the whole numbers, then add the numerators; this gives us 5 9/10.  The cow produces 5 9/10 liters in the evening.

To find the total amount produced that day, add this number to the amount in the morning:

5 9/10 + 2 3/5

The common denominator is 10 again.  Changing 2 3/5 to tenths is still 2 6/10:

5 9/10 + 2 6/10 = 7 15/10

15/10 is improper.  10 will go into 15 one time; this is the whole number.  We add this to 7, giving us 8.  This leaves us with 15-10=5 for the numerator:

8 5/10

This simplifies to 8 1/2.

Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 7.5 parts
Hunter-Best [27]

Answer:

The value of the test statistic is t = 2.1

Step-by-step explanation:

Our test statistic is:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the expected value, \sigma is the standard deviation and n is the size of the sample.

The level of ozone normally found is 7.5 parts/million (ppm).

This means that \mu = 7.5

The mean of 24 samples is 7.8 ppm with a standard deviation of 0.7.

This means that X = 7.8, \sigma = 0.7, n = 24

Test Statistic:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

t = \frac{7.8 - 7.5}{\frac{0.7}{\sqrt{24}}}

t = 2.1

The value of the test statistic is t = 2.1

A heated piece of metal cools according to the function c(x) = (.5)^x − 11, where x is measured in hours. A device is added that
Goryan [66]

Answer:

The temperature of metal after five years =  -18.96875

Step-by-step explanation:

Given : Function c(x) = (0.5)^x-11

where x is measured in hours

Another function is added h(x)=-x-3

therefore, the resultant function f(x)=h(x)+c(x)

f(x) = (0.5)^x-11-x-3

For x=5

f(5) = (0.5)^5-11-5-3

f(5) = (0.03125)-19

f(5) = -18.96875

Therefore, The temperature of metal after five years = -18.96875
