Using it's concept, the probabilities are given as follows:

19. A. 1/3.

20. F. 1/6.

<h3>What is a probability?</h3>

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, there are 1 + 1 + 3 + 4 + 3 = 12 papers. 4 have a score of 6, hence, in item 19, the probability is:

p = 4/12 = 1/3.

Which means that option A is correct.

2 papers have a score greater than 12, hence the probability in item 20 is given by:

p = 2/12 = 1/6.

Which means that option F is correct.

Quadrilateral JKLM is a rhombus. The diagonals intersect at N. If angle JNK equals 5x - 15, find the value of x.

VLD [36.1K]

One property of a rhombus is that the diagonals are perpendicular. This means that the diagonals intersect at 90 degree angles (right angles).

So we know that angle JNK is 90 degrees

angle JNK = 90 degrees
5x - 15 = 90
5x - 15 + 15 = 90+15
5x = 105
5x/5 = 105/5
x = 21

Answer: x = 21

Answer:

m<ACD = $50^{o}$

Step-by-step explanation:

From the question given, ΔACD is a right angled triangle. Then we can apply one of the properties of a triangle to it.

In the triangle ACD:

<ACD + <DAC + <ADC = 180 (sum of angles in a triangle)

<ACD + 40 + 90 = 180

<ACD + 130 = 180

<ACD = 180 - 130

<ACD = $50^{o}$

With the application of the property of the sum of interior angles of a triangle, the measure of <ACD is $50^{o}$ .

In an arithmetic sequence, the nth term an is given by the formula An=a1+(n−1)d, where a1is the first term and d is the common

Olin [163]

Answer: 433

Step-by-step explanation:

The given sequence : 19,42,65,88,...

We can see that the terms ha common difference as :-

$42-19=23\\65-42=23\\88-65=23$

Thus, its an Arithmetic progression with common difference (d)=23

The formula to find the nth term is :-

$a_n=a_1+(n-1)d$

Now, the 19th term of the given sequence :-

$a_{19}=19+(19-1)(23)\\\\=19+(18)(23)\\\\=19+414=433$

Hence, the 19th term of 19,42,65,88,... is 433.
