If Matrix A has dimensions 1x4 and Matrix B has dimensions 3x4, can these be multiplied?
Kipish [7]
Answer: No. You cannot multiply the matrices in any order. A*B is not defined. Also, B*A is not defined.

------------------------------------------------------------------------

Explanation: 

Matrix A has 1 row, and 4 columns. 
Matrix B has 3 rows, and 4 columns

In order for A*B to be possible, A has to have the same number as columns as B has rows. In other words, the inner dimensions have to match up. The '4' in '1x4' needs to match up with the '3' in the '3x4'. This match doesn't happen. 

The same story happens with B*A, just things have been flipped. 

B has 3 rows, 4 columns
A has 1 row, 4 columns

The "4 columns" of B does not match with "1 row" of A.

In a sample of 50 randomly selected students at a school, 38 students eat breakfast every morning. There are 652 students in the
Romashka-Z-Leto [24]
For the sample:
\frac{38}{50} = 0.76 = 76\%

Applying this to the whole population:

652 \times \frac {38}{50} = 495.52

Since we can't have "0.52 of a person" we roudn to the neares whole, or 496.

If the measure of ZB is 40°, what measures can ZA and
lubasha [3.4K]

Answer: 30° and 110°

55° and 85°

70° and 70°

The sum of angles in a triangle is 180°. Therefore, since an angle has been given as 40°, the remaining angles will be:

= 180° - 40°

= 140°

Therefore,

30° + 110° = 140°

55° + 85° = 140°

70° + 70° = 140°
