Mathematics
1 answer:
cricket20 [7]3 years ago
6 0

Answer:

\left[\begin{array}{cc}6&18\\\end{array}\right]

Step-by-step explanation:

To find the product of the matrices: \left[\begin{array}{cc}4&2\\\end{array}\right] × \left[\begin{array}{cc}-2&5\\7&-1\\\end{array}\right]

Multiply rows of the first matrix by the columns of the second matrix.

(4 × (–2) + 2 × 7          4 × 5 + 2 × (–1))

After simplifying this, we get the product \left[\begin{array}{cc}6&18\\\end{array}\right]

Hence, \left[\begin{array}{cc}4&2\\\end{array}\right] × \left[\begin{array}{cc}-2&5\\7&-1\\\end{array}\right] = \left[\begin{array}{cc}6&18\\\end{array}\right]

100 points for right answer Identify the correct explanation for why the triangles are similar. Then find SQ and TP.
STALIN [3.7K]

Answer:

Second one

Step-by-step explanation:

They have one angle (R) in common

Also,

Angles T & S and P & Q are equal because they are corresponding angles.

RS/RT = SQ/TP

4/(4+4) = 2x/(x+6)

4x = x + 6

3x = 6

x = 2

SQ = 2(2) = 4

TP = 2 + 6 = 8

Find the slope of the line that passes through (6,5) and (3,4)
vodomira [7]

Answer:

m = 1/3x

Step-by-step explanation:

slope = y^2 - y^1 / x^2 - x^1

m = 4 - 5 / 3 - 6

m = -1 / -3

m = 1/3

m = 1/3x --> the slope

The average number of road accidents that occur on a particular stretch of road during a year is 11.
maks197457 [2]

Answer:

0.06

Step-by-step explanation:

Given that :

Average number of road accident (n) = 11

Probability of observing exactly 7 accident o. The stretch of road next year

Poisson random variable (k) = 7

Using the poisson distribution formula :

P(x = k) = (n^k * e^-n) / k!

P(x = 7) = (11^7 × e^-11) / 7!

P(x = 7) = (19487171 × 0.0000167017) / 5040

P(x = 7) = 325.4688838907 / 5040

P(x = 7) = 0.0645771

= 0.06
