Answer:

71,150

Step-by-step explanation:

take seven percent of the subscribers and subtract it from the subscribers of the year before.

the start 93 800

loss 6,566

year 1: 87,212

loss 6,104.04

year 2: 81,107.16

loss 5.677.5012

year 3: 75,429.6588

loss 5,280.076116

year 4: 70,149.58

rounds up to 71,150

make sure to round the decimal at the very end, if you don't you will get a different answer

weqwewe [10]

Answer: -15 meters


Step-by-step explanation:

Given: The Tunnel of Fear ride climbs straight up to its peak above the ground = 50 meters or +50 meters

Then, it drops into an underground tunnel  = 65 meters or -65 meters

Thus, the elevation of the tunnel relative to the ground= +50-65=-15 meters

Hence, the elevation of the tunnel relative to the ground= -15 meters.

Sophie [7]

Answer:

That probability is 0.1838 or 18.4% or enter 18.4

Step-by-step explanation:

mean 35 sd 5

20 is 3 sd s to the left of the mean

30 is 1 sd to the left.

The empirical rule has 68% within 1 sd or 34% on one side

It has 95% within 2 sd or 47.5% on one side

It has 99.7% within 3 sd or 49.85% on one side

Therefore between 3 sd and 1 sd on one side is 49.85-34=15.85% or enter 15.9

mean of 48 sd 7

between 48 and 55 is between -1 and 0 sd or 34% enter 34. The last one doesn't seem to post easily:z=(x-mean)/sd or z< (1217-1481)/293 or z <-264/293 or -0.901,

That probability is 0.1838 or 18.4% or enter 18.4

Answer:

Please find attached the required graph of the equation, y = x² - 2·x - 8, created using MS Excel

Step-by-step explanation:

The given function required to be plot is y = x² - 2·x - 8

Therefore, the coordinates of the vertex of the parabola formed by the equation (h, k) is given as follows;

h = -(-2)/(2×1) = 1

k = 1² - 2×1 - 8 = -9

The coordinates of the vertex = (1, -9)

The roots of the equation is given when y = 0, as follows;

At the roots, we have;

x² - 2·x - 8 = 0

By factorizing, we get

x² - 2·x - 8 = (x - 4)·(x + 2) = 0

Therefore. the roots of the equation are;

x = 4, and x = -2

The coordinates of the roots are;

(4, 0), and (-2, 0)

Two other points can be found at when x = 3 and when x = 0 as follows;

When x = 3, we have;

y = 3² - 2×3 - 8 = -5

(3, -5)

When x  = 0, we have;

y = 0² - 2×0 - 8 = -8

(0, -8)

The five points are;

(1, -9), (4, 0), (-2, 0), (3, -5), (0, -8)

The graph of the equation created using MS Excel showing the five points is attached.
