[tex]KQ = PN[/tex]
We can't state that because we don't know if ∠NPK is 90º
Triangle KPN is similar to triangle KQN
It is the same case as the alternative a, we can't say the triangles are similar because we don't the angles for KPN. We know that LN is perpendicular to NP, but we don't if NP is perpendicular to PK, ∠NPK might be 89,9º, that is almost 90º.
KP = 0.5 LN
Once the four sides of the square are equal, LQ = QN. But from the picture we can only state that KP length is approximately the length of NQ (or 0.5 LN)
PN || KM
That's the correct answer! Once ∠QNP is 90º, PN is perpendicular to KM.

The ratio of red marbles to blue marbles in a bag is 2 to 5. If there are 60
more blue marbles than red marbles in the bag, how many marbles are
there all together?
Answers
Answer:
140
Step-by-step explanation:
Let's call the red and blue marbles 2x and 5x. We know that 5x = 2x + 60, so x = 20. The sum of all marbles in the bag is 2x + 5x = 7x which is 7 * 20 = 140 marbles. Hope this helps!
Answer:
84 in all.
Step-by-step explanation:
if there are 2 red marbles to every 5 marble than 60 / 5 = 12, 12 x 2 = 24 + 60 = 84.
A group of 72 children completed a survey on what kind of sport they like. The choices were: Chess, Swimming, and Football. Everyone liked at least one sport except 7 kids, which doesn't like any of these three kind of sports. 12 children liked Chess and Football but not Swimming, 16 children liked Chess and Swimming but not Football, 8 children liked Swimming and Football but not Chess, 10 children liked Chess only, 40 children liked Swimming, 32 student liked Football.
a)Find the number of kids who liked Swimming and Football.
b)What is the probability that a randomly-chosen child from this group likes either Chess or Swimming but not Football?
c)What is the probability that a randomly-chosen child from this group does not like active kinds of sport?
Answers
Answer:
see below
Step-by-step explanation:
Let C = chess
S = swimming
F = football
x = football only
y = all three sports
z = swimming only
x+y+ 8+12 = 32 those who like football
y+z+8+16 = 40 those who like swimming
7+x+8+y+12+10+16+z = 72 all children
Simplifying these equations
x+y = 32-20 = 12
y+z = 40-24 = 16
x+y +z = 72-53 = 19
Substituting x+y = 12 into the last equation
12 +z = 19
z = 7
y+z = 16
y = 9
x+y =12
x =5
Swimming only is 7
Football only is 5
Swimming and football y+8 = 9+8 = 17
P( chess or swimming but not football) = (10+16+z)/ total
=(10+16+7)/ total
=33/72
P( no active sport) = chess only or no sport/total
=(10+7)/72

Step-by-step explanation:
you know what output you get from the input.
For example, you know that if you put in -5, you get -2, or if you put in 4, you get -2.
Even though there are two inputs for one output, it is still a function.
------------------------------------------------------------------------
If there are two outputs for one input, it is not a function.
For example, on d, when -5 is an input, you don't know if you're going to get 3 or 7. So, it's not a function.

The one-year survival rate for pancreatic cancer is 20%. Of 12 people diagnosed with pancreatic cancer at one hospital, 6 survived one year. What is the probability of that happening.
Answers
Answer:
The required probability is 0.0155.
Step-by-step explanation:
We are given that the one-year survival rate for pancreatic cancer is 20%.
Of 12 people diagnosed with pancreatic cancer at one hospital, 6 survived one year.
The above situation can be represented through binomial distribution;
[tex]P(X=r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r} ; x = 0,1,2,3,......[/tex]
where, n = number of trials (samples) taken = 12 people
r = number of success = 6 survived
p = probability of success which in our question is probability of
one-year survival rate for pancreatic cancer, i.e; p = 20%
Let X = Number of people survived one year
So, X ~ Binom(n = 12 , p = 0.20)
Now, the probability that 6 survived one year is given by = P(X = 6)
P(X = 6) = [tex]\binom{12}{6} \times 0.20^{6} \times (1-0.20)^{12-6}[/tex]
= [tex]924 \times 0.20^{6} \times 0.80^{6}[/tex]
= 0.0155

At a charity raffle event they are giving out tickets labeled 1 through 10 when people come through the doors. If you are given an even-numbered ticket, you are given a prize at the end of the evening. The table shows the results of 500 guests. What is the relative frequency for the guests who will receive a prize? Ticket Number 1 2 3 4 5 6 7 8 9 10 Frequency 48 42 41 56 67 43 39 41 55 68
Answers
Answer:
Relative frequency for guest who will win the prize:
Relative frequency = 50%
Step-by-step explanation:
Total No. of guest = 500
No. of Guests with even-numbered tickets:
Ticket NO. 2 = 42
Ticket NO. 4 = 56
Ticket NO. 6 = 43
Ticket NO. 8 = 41
Ticket NO. 10 = 68
Total No. of Guest with even-numbered ticket = 42+56+43+41+68
Total No. of Guest with even-numbered ticket = 250
So.
Relative frequency = (frequency of desirable event/ total frequency) · 100
Relative frequency = (250/500)· 100
Relative frequency = 50%

the ratio of the cost of one meter of polyester fabric to the cost of one meter of one silk is 2:9 complete the table of costs
Answers
Answer:
Polyester Fabric = 4 || 8 || 16 || 22
Silk Fabric = 18 || 36 || 72 || 99
Step-by-step explanation:
Given:
The above table
Ratio; Polyester Fabric : Silk = 2:9
Required
Complete the above table
Provided that the ratio of the cost of one meter of polyester fabric to the cost of one meter of one silk is 2:9;
To complete rows of polyester fabric
We simply multiply cost by ratio of polyester fabric ratio (2)
To complete rows of silk fabric
We simply multiply cost by ratio of silk fabric ratio (9)
This is as follows:
When length = 2m
Polyester Fabric = 2 * 2 = 4
Silk Fabric = 2 * 9 = 18
When length = 4m
Polyester Fabric = 4 * 2 = 8
Silk Fabric = 4 * 9 = 36
When length = 8m
Polyester Fabric = 8 * 2 = 16
Silk Fabric = 8 * 9 = 72
When length = 11m
Polyester Fabric = 11 * 2 = 22
Silk Fabric = 11 * 9 = 99
Hence, the complete table is as follows:
Polyester Fabric = 4 || 8 || 16 || 22
Silk Fabric = 18 || 36 || 72 || 99

Answers
Step-by-step explanation:
I'm not sure what the square root method is, but I'm assuming that you factor.
This is how I would solve it:
[tex]h = - 16 {t}^{2} + 36 \\ 0 = - 16 {t}^{2} + 36 \\ 0 = - 4(4 {t}^{2} - 9) \\ 0 = (2t - 3)(2t + 3) \\ t = \frac{3}{2} \\ t = - \frac{3}{2} [/tex]
Since time can't be negative, you rule out the -3/2.

what’s the midsegment
Answers
Answer:
17 units
Step-by-step explanation:
The midsegment of a triangle theorem states that:
The midsegment is 1/2 of it's parallel side.
So,
6x + 5 = 1/2(4x + 26)
6x + 5 = 2x + 13
6x - 2x + 5 = 13
4x + 5 = 13
4x = 13 - 5
4x = 8
x = 8 ÷ 4
x = 2
Substitute x to the midsegment.
6x + 5
6(2) + 5
12 + 5
