The temperature rose 6.4 Fahrenheit between noon and 5 PM and fill 34.7 Fahrenheit from 5 PM to 10 PM if the temperature at noon
mars1129 [50]

Answer:

Given,

Between 6am and 10am the temperature rose by 5 degrees F,

So, the total changes in temperature between 6 AM and 10 AM = +5°

And, Between 10am and 2pm the temperature rose by 6 degrees F

⇒ The total changes in temperature between 10am and 2pm = + 6° F,

Also, Between 2pm and 6pm the temperature rose by 0 degrees C,

⇒ The total changes in temperature between 2pm and 6pm = +0°,

Hence, the total changes in temperature since 6 AM =  the total changes between 6 AM and 10 AM +  The total changes between 10am and 2pm + The total changes between 2pm and 6pm

=  5° + 6° + 0

= 11°

Hence, the + sign shows the rise in temperature,

And, it is rose by 11°.

Tju [1.3M]

The <em><u>correct answer</u></em> is:

The equation has no solution; therefore, the system of equations has no solution.

Explanation:

When solving a system of equations, after we combine the equations, if we find that there is no solution, that means that there is no solution to the entire system of equations.

Cereal. A dietician obtains the amounts of sugar (incentigrams) from 100 centigrams (or 1 gram) in each of 10 differentcereals,
nadezda [96]

Answer:

Range is 44

mean is 29.7

variance is 289.56

standard deviation is 17.016

Step-by-step explanation:

The data given as follows

3, 24, 30, 47, 43, 7, 47,13, 44, 39

Range = maximum - minimum

             = 47 -3 = 44

mean = \frac{3+24+30+47+43+7+47+13+44+39}{10} = 297/10 = 29.7

variance = \frac{sum xi^2 }{N} - mean^2 }

              = 289.56

SD = \sqrt{variance}  = 17.016

The standard deviation of the given data is not a good measure as the range and standard deviation are far apart. The standard deviation gives how the given data is dispersed from the mean or expected value, while the range gives a rough idea of variability of the data.
