Jimmie graphs a quadratic function and finds that its zeros are at x=2 and x=3. Which function could Jimmie have graphed?

HACTEHA [7]

The function Jammie graphed is $x^2-5x+6=0$

Step-by-step explanation:

The zeros of quadratic function are at x=2 and x=3

We can write them as:

$x-2=0\,\,and\,\,x-3=0\\or\\(x-2)(x-3)=0$

Multiplying them

$(x-2)(x-3)=0\\x(x-3)-2(x-3)=0\\x^2-3x-2x+6=0\\x^2-5x+6=0$

So, The function Jammie graphed is $x^2-5x+6=0$

For the equations given below, which statement is true?

seraphim [82]

Answer:

D. The equations do not have the same solution because the second eqlition can never be obtained when multiplying the first

equation by any value

Step-by-step explanation:

-21=14 Equ(1)

6.1=-42 Equ(2)

Multiplying the first equation by -3 will give

-63= -42

Which is not equivalent to the second equation

Multiplying the first equation by 3, we have

-63=42

Not equivalent to the second equation

Multiplying both sides of the first equation by -4, we have

84=56

Not equivalent to the second equation

D. The equations do not have the same solution because the second eqlition can never be obtained when multiplying the first

equation by any value

O Question 51 pt 1DetailsThe table below gives the number of hours spent watching TV last week by a sample of 24 children. Find

Dmitriy789 [7]

Recall that the mean of a given set of numbers is the sum of the numbers divided by the number of numbers, therefore, the mean of the dataset is:

$\bar{x}=59.54.$

Now, the range of a data set is the difference between the maximum and the minimum, in this case, the maximum is 99, and the minimum is 15 therefore, the range is:

$99-15=84.$

Finally, the standard deviation is given by the following formula:

$s=\frac{1}{N-1}\sum(x_i-\bar{x})^2,$

where N is the sample size, x_i is an element of the set, and x^- is the mean. The standard deviation of the set is:

$s=24.35.$ <h2>Answer: </h2> $\begin{gathered} mean=59.54, \\ range=84, \\ standard\text{ deviation=24.35.} \end{gathered}$
