PLS HELP ME! Write a rule (function) for the data in this table.

Answer:

x=-13

Step-by-step explanation:

All you have to do is divide 8 by both sides because you want to get x by itself.

Answer:

A bag contains 8 red marbles, 3 blue marbles and 7 green marbles.

Total = 18 marbles.

Probability of drawing three red marbles = probability of drawing one red without replacement + probab of drawing another without reeplacement + probab of drawing a third without replacement.

Probability of drawing three red marbles = 8/18 + 7/17 + 6/16 = 0.4444 + 0.4118 + 0.3750 = 1.2312.

Answer:

d. 7.3

Step-by-step explanation:

To get the standard deviation of a population of data, first take the sum of all the values, and divide it by the count to get the mean (average).

75 [1] + 90 [2] + 75 [3] + 80 [4] + 90 [5] + 80 [6] + 100 [7] + 85 [8] + 80 [9] + 85 [10] = 840.

Then divide by the count which is 10.

840/10 = 84 [This is the mean of the data.]

Then subtract every point of data from the mean and square it:

(75-84)^2 + (90-84)^2 + (75-84)^2 + (80-84)^2 + (90-84)^2 + (80-84)^2 + (100-84)^2 + (85-84)^2 + (80-84)^2 + (85-84)^2 = 81 + 36 + 81 + 16 + 36 + 16 + 256 + 1 + 16 + 1 = 540.

Then to get the variance, divide this all by the count.

540/10 = 54 [This is the variance of the data.]

Then all you have to do to get the standard deviation is take the square root of the variance.

√54 = 3√6 ≈ 7.3 [This is the standard deviation of the data.]

Answer:

66

Step-by-step explanation:

Answer:

Lets numeralise the question,

According to question 32+ ? = 98

So if we take the unknown value as x then we will get,

32+x=98

So by transposing we get,

x=98-32

=  66

So 66 should be added to 32 to get 98

Answer:

34.1 degrees

Step-by-step explanation:

given that the temperature drops 3.1 degrees for every thousand feet of elevation.

for an altitude of 11,000 feet (i.e 11 x 1000 feet), the temperature (compared to ground level) would drop,

= 3.1 deg / 1000-foot   x   11,000 feet

= 34.1 degrees

Answer and Step-by-step explanation:

SOLUTION:

Given function:

h (x, y, z) = ln (x2 + y2 – 1) + y +6z,  p0(1, 1, 0)

Derivatives of the function:

∂h / ∂x = (1 / x2 + y2 -1). (2x)

          = 2x / x2 + y2 -1

∂h/∂y = (1 / x2 + y2 – 1) (2y + 1)

          = (2y / x2 + y2 -1) + 1

∂h / ∂z = 6

Now compute the partial derivatives:

∂h (1, 1, 0) / ∂x = 2(1) / 1 +1 -1

                            = 2

∂h(1, 1, 0) / ∂y =( 2(1) / 1 +1 -1) + 1

                           = 3

∂h (1, 1, 0) / ∂z = 6

Δh (1,1,0) = ( 2, 3, 6)

The definition of gradient is:

Δf (x, y, z) = (∂f / ∂x , ∂f / ∂y)

Put the coordinate values to arrive at solution:

Umax = Δh (1,1,0) / | Δh (1,1,0) |

      = (2, 3, 6) / |2, 3, 6|

     = (2, 3, 6) / √(22+33+62)

   = (2, 3, 6) / √49

    = (2, 3, 6) / 7

= (2/7 , 3/7, 6/7)

Umin = - U max = ( -2/7, -3/7, -6/7)

Compute direction by finding unit vector:

Du h max = Δh (1,1,0)  . u max

                 = (2, 3, 6) . (2/7, 3/7, 6/7)

                 = 2(2/7) + 3(3/7) + 6(6/7)

                 = 4/7 +  9/7 +36/ 7

                  = 49 / 7

                  = 7

Du h min = -Du h max

                = -7

Answer:

m = -3/2

Step-by-step explanation:

m = (y2-y1)/(x2-x1)

m = (-1-2)/(3-1)

m = -3/2

Answer:

the answer is 0.9-1.0

Step-by-step explanation:

the answer is that because my teacher gave me the answer

Answer:

Number of jar Sohie's mom can make can be found out by dividing the total amount by the amount in one jar, so we can frame a equation like this,

Let the number of total jar be x,

x = (1 7/10) / 1/2

That is the answer, let us solve this equation,

x = 1 7/10 / 1/2

=> x = 17/10 * 2/1

=> x = 17/5 * 1/1

=> x = 17/5

17/5 = 3.40

Answer:

18

Step-by-step explanation:

1. Create the ratio 12:9

The first number in the ratio is where the length of the shadow will go. The second number is where the length of the building will go.

2. Subtract 21 by 12 to find out how much we have to add to 9. (21-12=9)

3. Add 9 to 9. (18)

We now have 21:18.

Answer:

slope = -3/14

Step-by-step explanation:

y1  - y2 / x1 - x2

They gave you one value, two total coordinates

5-5 = 1

-3 - 11

-14

1/-14

y=1/-14 + b

11= 1/-14(-3) + b

11 = -3/14 + b

17 + 14

b = 15 3/14
