How does the multiplicity of a zero affect the graph of the polynomial function? Select answers from the drop-down menus to corr

miskamm [114]

Answer:

3 points: x = 1, x = 2 and x = 4

1 point: x = 6

Cross

Step-by-step explanation:

Points to remember:

A zero of odd multiplicity will cross through the x-axis
A zero of event multiplicity will only touch the axis i.e. be tangent to it.

The given zeros are:

1 with multiplicity of 1 (Odd Multiplicity)
2 with multiplicity of 3 (Odd Multiplicity)
4 with multiplicity of 1 (Odd Multiplicity)
6 with multiplicity of 2 (Even Multiplicity)

The graph will cross x-axis at zeros with odd multiplicity. Since zeros with odd multiplicity are 3, the graph will cross the x-axis at 3 points: x = 1, x = 2 and x = 4

Similarly, the zero of even multiplicity is 1, so the graph will touch the x-axis at 1 point only: x = 6

At the zero of 2, the graph of the function will cross the x-axis.

Suppose on a certain test, fifty students earn a perfect score and fifty students earn a zero. determine the mean grade and stan

kodGreya [7K]

Answer:

Mean=50.

standard deviation=50.

Step-by-step explanation:

Let the perfect score be 100.

The mean(average) of a data is given by: $Mean=\frac{sum of data points}{number of data points}$

Here the number of data points are 100. out of which 50 attains a value 100,and 50 attains value 0.

so, sum of data points=50×100+50×0=5000.

$Mean=\frac{5000}{100}$

Mean=50.

"Now the standard deviation of data points are calculated by firstly subtracting mean from every entry and then square the number and take it as new entry and calculate the mean of the new data entry and lastly taking the square root of this new mean".

Here if 50 is subtracted from each entry the new entry will have 50 entries as '50' and 50 entries as '-50'.

next on squaring we will have all the 100 entries as '2500'.

now the mean of these entries is: $\frac{2500\times100}{100}$
