The frequency table shows the results of a survey comparing the number of beach towels sold for full price and at a discount dur

ing each of the three summer months.
A 4-column table with 4 rows titled beach towel sales. The first column has no label with entries month 1, month 2, month 3, total. The second column is labeled full price with entries 49, 120, 101, 270. The third column is labeled discounted with entries 1, 5, 24, 30. The fourth column is labeled total with entries 50, 125, 125, 300.

The store owner converts the frequency table to a conditional relative frequency table by row.

A 4-column table with 4 rows titled beach towel sales. The first column has no label with entries month 1, month 2, month 3, total. The second column is labeled full price with entries 0.98, 0.96, 0.808, X. The third column is labeled discounted with entries 0.02, 0.04, 0.192, Y. The fourth column is labeled total with entries 1.0, 1.0, 1.0, 1.0.

Which value should he use for X? Round to the nearest hundredth.

Answer:

0.90

Step-by-step explanation:

                     full price    discounted        total

month 1               49              1                     50

month 2             120             5                    125

month 3              101            24                   125

total                    270           30                  300

                     full price    discounted        total

month 1            0.98           0.02                   1

month 2           0.96           0.04                   1

month 3         0.808          0.192                   1

total              x = 0.9       y = 0.10                 1

x = 270 / 300 = 0.90

y = 30 / 300 = 0.10

Answer:

30

Step-by-step explanation:

20+11=31

It can't be exactly 31 but it can be any number less than 31, so the nearest whole number down is 30

What is the discontinuity and zero of the function f(x) = the quantity of 3 x squared plus x minus 4, all over x minus 1? A. Dis
Firlakuza [10]

Answer:

The correct option is D. Discontinuity at (1, 7), zero at (negative four thirds, 0)  

Step-by-step explanation:

\text{The function is given to be : }f(x)=\frac{3x^2+x-4}{x-1}\\\\\implies f(x)=\frac{(3x+4)(x-1)}{(x-1)}

To find the point of discontinuity :

Put the denominator equal to 0

⇒ x - 1 = 0

⇒ x = 1

Also, if the factor (x - 1) gets cancel, then it becomes a hole rather than a asymptote , ⇒ y = 3x + 4 at x = 1

⇒ y = 7

So, Point of discontinuity : (1, 7)

And the zero is : after cancelling the factor (x - 1) put the remaining factor = 0

⇒ 3x + 4 = 0

⇒ 3x = -4

⇒ x = negative four thirds ( zero of the function)

Therefore, The correct option is D. Discontinuity at (1, 7), zero at (negative four thirds, 0)

What is the equation of the quadratic graph with a focus of (3, 1) and a directrix of y = 5?
lbvjy [14]

Answer:

The equation of the quadratic graph is f(x)= - (1/8) (x-3)^2 + 3 (second option)

Step-by-step explanation:

Focus: F=(3,1)=(xf, yf)→xf=3, yf=1

Directrix: y=5 (horizontal line), then the axis of the parabola is vertical, and the equation has the form:

f(x)=[1 / (4p)] (x-h)^2+k

where Vertex: V=(h,k)

The directix y=5 must intercept the axis of the parabola at the point (3,5), and the vertex is the midpoint between this point and the focus:

Vertex is the midpoint between (3,5) and (3,1):

h=(3+3)/2→h=6/2→h=3

k=(5+1)/2→k=6/2→k=3

Vertex: V=(h,k)→V=(3,3)

p=yf-k→p=1-3→p=-2

Replacing the values in the equation:

f(x)= [ 1 / (4(-2)) ] (x-3)^2 + 3

f(x)=[ 1 / (-8) ] (x-3)^2 + 3

f(x)= - (1/8) (x-3)^2 + 3
