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 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

Step-by-step explanation:

Angle x and angle BOC are supplementary. We know that Supplementary angles add up to 180 degrees

180 = x + 156

Subtract 156 from both sides.

24 = x

Answer:  48 cubes in the new box

Step-by-step explanation:

Doubling the length and the width is 2×2, so 4 times the original capacity.

4×12 = 48

It is not necessary to compute the volume. The dimensions could be anything. It's the number of cubes that count.

Answer:

Miranda can bake 30 cookies with 6 scoops of flour.

Step-by-step explanation:

The rate is 5 cookies for every scoop of flour. to figure this out we need to divide 15 by three, to get 5, so the rate ends up being 5:1

Next, to find out the number of cookies, we need to multiply 5 by 6 to get 30. Therefore, Miranda can bake 30 cookies.

Answer:

Step-by-step explanation:

3x + 10 + 3x - 28 = 180

6x = 180 - 10 + 28

x = 198/6

x = 33

substitute the value of x = 33 back into the equation to solve for each angle

= 3x + 10

= 3(33) + 10

= 109

= 3x - 28

= 3(33) - 28

= 71

Step-by-step explanation:

The answer is probability distribution

What is probability distribution?

Probability distribution is a function used to express all the range of random variables and the chances or possibilities of their occurrence.

Basically the function assigns probabilities to some sets of  values.

Also There are three major types of probabilities:

Theoretical Probability.

Experimental Probability.

Axiomatic Probability.

A​ relative-frequency distribution is to a variable as a​ Probability distribution is to a random variable.

Probability is a type of mathematics which deals with numerical descriptions of how likely an event would occur, or how likely it is that a the occurrence would be true.

The probability of an event is usually between 0 and 1, where 0 represent impossibility and 1 represents the chance of it occurring.

Answer:

B.

Step-by-step explanation:

First you need to figure out how many numbers there are, so with this you can simply count 10. Then use the formula to plug in the numbers: 10(22-77)/2 to get the answer.

The required sum of the arithmetic progression is -275.

The arithmetic sequence is given 22, 11, 0, -11, ..., –77, sum of the sequence is to be determined.

Arithmetic progression is the series of numbers that have common differences between adjacent values

Here,
first term (a) = 22
Last term (l) = -77

Now,
l = a + (n - 1)d
-77 = 22 + (n - 1) *(-11)
-77 - 22 = (n - 1)(-11)
n - 1 = 9
n = 10

Now,
sum of the arithmetic sequence,
s = n / 2 [a + l]
s = 10 / 2 [22 - 77]
s = 5 [-55]
s = -275

Thus, the required sum of the arithmetic progression is -275.

Step-by-step explanation:

The owner of a small deli is trying to decide whether to continue or discontinue selling magazines.

His suspicion that only 10.7% of his customers by a magazine (daily) is correct.

What is the probability that exactly 4 out of the first 13 customers (on this day) buy a magazine?

The probability is:

10.7% × 4/13  = 10.7/100 × 4/13  = 0.107 × 0.308  = 0.0329 ≅ 0.03 to two decimal places

Solution,

Change in water level is [tex]1\dfrac{1}{2}\ \text{inches}=\dfrac{3}{2}\ \text{inches}[/tex]

The water level of a lake fell by [tex]1\dfrac{1}{2}[/tex]  inches  during a [tex]1\dfrac{2}{3}\ \text{or}\ \dfrac{5}{3}[/tex]week-long dry spell.

Average rate at which the water level changed  every week is given by :

[tex]R=\dfrac{1\dfrac{1}{2}}{1\dfrac{2}{3}}\\\\R=\dfrac{\dfrac{3}{2}}{\dfrac{5}{3}}\\\\R=\dfrac{3}{2}\times \dfrac{3}{5}\\R=\dfrac{9}{10}\\\\R=0.9[/tex]

Hence, the average rate is 0.9 every week.

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.]

The translation of the point (1, -4) when you move left 4 units and down 1 unit will be (0,-8).

Translation in mathematics is the movement of a shape in any direction—left, right, up, or down—without turning. They are congruent if the translated shapes (or the image) seem to be the same size as the original shapes. They have only changed their direction or directions.

Given that you start at (1, -4). You move left 4 units and down 1 unit. The translated point will be calculated as,

(1, -4)  ⇒ ( 1 - 1 , -4 - 4)

( 1 , 4 ) ⇒ ( 0 , -8)

Therefore, the translation of the point (1, -4) when you move left 4 units and down 1 unit will be (0,-8).
