Use the cumulative frequencies to figure out what the individual frequencies would be. Check out the attached image for the table of x values with their corresponding frequency (f) values. Note how the partial sums add up to the cumulative frequency values.

Once you know the frequency f values, multiply each x and f pair together in each row. The column labeled "x*f" represents each product. Afterward, add up everything in the x*f column to get the final answer 6.8

Answer:

Put the dot on the 5 on the Y-axis

Step-by-step explanation:

Put the initial dot on the 5 on the y-axis (vertical), then it's rise over run if plotting a line. Since it's 3/4 you would go up 3 and over to the right four. You can get the rest of the line by going down 3 from the initial point on five, down left 3.

Which of the following are geometric sequences?

Elenna [48]

A. 2,-2,2,-2,2,-2,2
C. 10,5,2.5,1.25,0.625,0.1325
and
D. 1,2,4,8,16,32
Are all geometric sequences

This means that each sequential # is derived by either multiplying or dividing by a number.

For instance, A. is found by multiplying each by - 1, B. is found by multiplying each by 1/2 (0.5), and D. is found by multiplying each by 2

The frequency of vibration of a piano string varies directly as the square root of the tension on the string and inversely as th

artcher [175]

Answer:

about 409.946 Hz

Step-by-step explanation:

The multiplier of frequency is (√(tension multiplier))/(length multiplier), so is ...

(√1.25)/1.2 = (5/12)√5 ≈ 0.931695

So, the longer, tighter string will have the lower frequency of about ...

0.931695×440 Hz ≈ 409.946 Hz
