The missing number in the given data that has a mean of 79 is: 60.

The mean of a data set is simply the average, that is, it is the sum of all data values divided by the number of data values.

Let x represent the missing number in the data. If the mean is 79, we would have the following:

(89 + 74 + 92 + 80 + x)/5 = 79

(335 + x)/5 = 79

335 + x = 5(79)

335 + x = 395

x = 395 - 335

x = 60

Missing number is: 60.

The temperature at a point (x, y) is T(x, y), measured in degrees Celsius. A bug crawls so that its position after t seconds is

aniked [119]

Answer:

10.50°C

Step-by-step explanation:

Given x = 2 + t , y = 1 + 1/2t where x and y are measured in centimeters. Also, the temperature function satisfies Tx(2, 2) = 9 and Ty(2, 2) = 3

The rate of change in temperature of the bug path can be expressed using the composite formula:

dT/dt = Tx(dx/dt) + Ty(dy/dt)

If x = 2+t; dx/dt = 1

If y = 1+12t; dy/dt = 1/2

Substituting the parameters gotten into dT/dt we will have;

dT/dt = 9(1)+3(1/2)

dT/dt = 9+1.5

dT/dt = 10.50°C/s

Hence the rate at which the temperature is rising along the bug's path is 10.50°C/s

What products are defined for these matrices?

Zarrin [17]

Answer:

Product is defined ${}$

(ML, MP, NM, PQ, PL, LP, MQ, LQ)

Product is not defined

(LM, PM, MN, QP, QM, NQ, QN, NL, LN, NP, PN, QL)

Step-by-step explanation:

During multiplication of matrices, the number of columns of the first matrix must be equal to the number of rows of the second matrix it is multiplying.

Therefore, we can only multiply a m×n matrix to a n×c matrix as follows;

We can only multiply (m×n)·(n×c) → Product is defined

We can not multiply (n×c)·(m×n) →∞ Product is not defined.
