Thr answer is the slope.
Hi there!
• Base, b = 8 units
• Altitude, a = 10 units
Area of Triangle =

× b × a =

× 8 × 10 = 40 units.
Hence,
Th' required area of triangle is 40 units

Answer:
8 and 2.529
Step-by-step explanation:
The computation of the mean and the standard deviation is shown below:
Given that
Total number of questions is n = 40
The Probability of correct answer is p = 
So, the probability of the wrong answer is q =
= 
Moreover, this is the binomial distribution
Based on the above information
The mean is


= 8
Now the variance is

= 
So, the standard deviation is

= 2.529
hence, the mean and the standard deviation is 8 and 2.529 respectively
Answer:
B. 1×3
Step-by-step explanation:
Given the first matrix as [ 4 -1 0] this is 1×3 (row by column)
The second matrix is [2 1 0 ] which is a 3×3 matrix
[-3 -7 2 ]
[1 -5 2]
Hence the answer matrix will be;
[1×3 ] *[3×3]----------------------cancel the shaded numbers to remain with
[1×3]
