Identify JK. JK and JM are tangent to W.
Answers
Answer:
B. 8
Step-by-step explanation:
Based on the tangent theorem, when two tangents meet at an external point of a circle, the length of the two tangents are said to be equal in length.
Therefore:
JK = JM
Substitute
5x - 12 = x + 4
Collect like terms
5x - x = 12 + 4
4x = 16
4x/4 = 16/4
x = 4
✔️JK = 5x - 12
Plug in the value of x
JK = 5(4) - 12
JK = 20 - 12
JK = 8
Lines that appear to be tangent are tangent. If O is the center of the circle, what is the value of x?

STEP
3
:
Pulling out like terms
3.1 Pull out like factors :
4x2 + 24x - 40 = 4 • (x2 + 6x - 10)
Trying to factor by splitting the middle term
3.2 Factoring x2 + 6x - 10
The first term is, x2 its coefficient is 1 .
The middle term is, +6x its coefficient is 6 .
The last term, "the constant", is -10
Step-1 : Multiply the coefficient of the first term by the constant 1 • -10 = -10
Step-2 : Find two factors of -10 whose sum equals the coefficient of the middle term, which is 6 .
-10 + 1 = -9
-5 + 2 = -3
-2 + 5 = 3
-1 + 10 = 9
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

There are six households in a rural community. Each household earns $40,000 per year. Suppose that a new resident builds a mansion in the community and that the income in the new household is $4 million per year. After the new resident arrives, the median household income has _____, and the mean household income has _____. increased; increased not changed; increased not changed; not changed increased; not changed
Answers
Answer:
Median income has not changed
Mean income has increased
Step-by-step explanation:
Initial number of houses = 6
Earning per household = $40,000
The initial mean :
$(40,000 * 6) / 6 = $40000
Initial median :
40000, 40000, 40000, 40000, 40000, 40000
= 1/2(n+1)th term,
Median = 40000
A 7th household earns 4,000,000
Mean = ((40000*6) + 4,000,000) / 7 = $605,714
Median = 1/2(n+1)th term
40000, 40000, 40000, 40000, 40000, 40000, 4000000
Median = 4th term = 40000

Hassan jarred 12 liters of jam after 6 days. How many days does Hassan need to
spend making jam if he wants to jar 14 liters of jam in all? Assume the relationship
is directly proportional.
Answers
Answer: 7 days
Step-by-step explanation: if he can make 12 liters in 6 days then you can divide 12 by 6 to know he can make 2 liters in 1 day. If he only needs 2 more liters, he only needs one more day and he has already spent 6 days and adding the one extra day, it would be 7 days
A university was interested in examining the overall effectiveness of its online statistics course, along with the effectiveness of particular aspects of the course. First, the university wanted to see whether the online course was better than a standard course. Second, the university wanted to know whether students learned best using Excel, using Minitab, or using no statistical package at all. The university randomly selected a group of 30 students and administered one of the different variants of the course (i.e., traditional or online, coupled with one of the three software options) to each student. The success of each variant was measured by the students' average improvement between a pre-test and a post-test.
i. Is this a controlled experiment or observational study?
ii. What are the explanatory variables?
A. The students mean pre-test average score.
B. Whether the course was online or traditional.
C. Whether the course was online or traditional and the statistical software used.
iii. The response variable is:
A. the students' mean post-test score.
B. the difference between the students' mean pre-test and post-test scores.
C. an evaluation of course quality provided by an independent rater.

B. 17.5
C. 20
D. 22
Answers
Answer:
22ft
Step-by-step explanation:
Find the diagram attached
Since the triangles are mirror images of each other, this shows that they are similar triangles
Taking the ratio of the sides of the triangle and equating it to a constant, we will have;
5.5/4 = x/16
Cross multiply
4 * x =5.5 * 16
4x = 88
x = 88/4
x = 22ft
Hence the required value of x is 22ft
