On average, the merchandise shop sells 80 CDs for every 1 vinyl record. Estimate how many vinyl records they are likely to sell
sp2606 [1]
The merchandise shop sells 80 CDs for every 1 vinyl record. We have to find how many vinyl records they are likely to sell if the merchandise shop sells 760 CDs:
         80  CDs -------------------- 1 vinyl record
        760 CDs --------------------- x vinyl records
     ---------------------------------------------------------
        80  : 760 = 1 : x
        80 x = 760
        x = 760 : 80
        x = 9.5  or 9 ( we need a whole number )
       Answer: They are likely to sell  9 vinyl records.

Jamie kicked a soccer ball that traveled along a path described by the parabola y = -x^2 +8x, where y equals the height of the s
andrey2020 [161]
We have that
<span>y = -x</span>²<span>+8x

we know that
when the ball hint the ground is the x-intercepts of the graph
the x-intercepts is for y=0
so
0=-x</span>²+8x--------> x²-8x=0----> x*(x-8)=0

the solution is
x=0
x=8

the x intercepts are the points (0,0) and (8,0)
the distance between the x intercepts points =[8-0]-----> 8 ft

the answer is
8 ft

see the attached figure

Which could be a conditional relative frequency table ???
user100 [1]

Answer:

The table that represents the conditional relative frequency is:

                           A                B                Total

C                        0.25           0.75             1.0

D                        0.35           0.65             1.0

Total                 0.30           0.70              1.0

Step-by-step explanation:

We know that a conditional relative frequency table is one:

In which the entries in each row is divided by the row total .

                        OR

In which the entries in each column is divided by the column total.

i.e. the frequency or quantity of an item is being compared either to row or to the column total.

Hence, from the given options, the table that represent the conditional relative frequency is:

                           A                B                Total

C                        0.25           0.75             1.0

D                        0.35           0.65             1.0

Total                 0.30           0.70              1.0
