Suppose the test scores on an exam show a normal distribution with a mean of 82 and a standard deviation of
Zanzabum

Answer:

a) Between 74 and 90

b) 81.86% of the scores are between 78 and 90

Step-by-step explanation:

a) According to the Empirical Rule, in a normal distribution, 95% of the data are within 2 standard deviations of the mean. Therefore, the range that 95% of the scores fall in is between 82-4(2)=74 and 82+4(2)=90.

b) The percent of scores that are between 78 and 90 is: normalcdf(lower,upper,μ,σ) = normalcdf(78,90,82,4) = 0.8185946784 ≈ 0.8186, or about 81.86% of the scores.

I’m not sure with this question help!
labwork [276]

Answer:  C.) 3 to the power of negative two, 1.3 x 10 to the power of negative one, 1/3, and 3 squared.

Step-by-step explanation:

3 to the power of negative 2 = 0.11111111111

3 squared is 1.73205080757

1.3 x 10 to the power of negative 1 = 0.13

1/3 converted to a decimal is 0.333

Now that we know what everything equals we know that anything that doesn't start with 3 squared is right and a little cheat is that only one of them start with 1/3 so we know that the second biggest is 1/3 so it is C.) 3 to the power of negative two, 1.3 x 10 to the power of negative one, 1/3, and 3 squared.

Part 10, What is the area of this figure? NO LINKS!!!​
Tamiku [17]

Answer:

shaded area  = 601 mm²

Step-by-step explanation:

Area of rectangle = Length * Breadth

Area of first section = 12 * 16 = 192 mm²

Area of 2nd middle section = 8 * ( 16 - 10 ) =  48 mm²

Area of the bottom section = 19 * 19 = 361 mm²

Area of total therefore = 192 mm² + 48 mm² + 361 mm²

                                      =  601 mm²
