Find scale factor

Scale factor:-

Yes Option A is correct

Answer:

A.  The edge lengths of the smaller figure are less than half those of the large figure.

[tex]\sf Scale\:factor=\dfrac13[/tex]

Step-by-step explanation:

From inspection of the graph, the pre-image is QRST and the dilated image is Q'R'S'T'.

We can see that Q'R'S'T' is a reduction of QRST since it is smaller.

Inspect the length of the corresponding line segments of both images and compare.

T'S' = 3 units

TS = 9 units

[tex]\sf \dfrac{T'S'}{TS}=\dfrac{3}{9}=\dfrac13[/tex]

Therefore, T'S' is [tex]\sf \frac13[/tex] the length of TS.

As [tex]\sf \frac13 < \frac12[/tex], the edge lengths of the smaller figure are less than half those of the large figure (answer option A)

The scale factor is the amount we have to multiply the sides of QRST by to get Q'R'S'T'.  Therefore, the scale factor for the side lengths in this dilation is [tex]\sf \frac13[/tex]

QS bisects PR.

⇒ PS ≅ RS

1.PQ ≅ RQ                       Given

2. PS ≅ RS                       QS bisects PR

3. QS ≅ QS                      Reflexive property

ΔPSQ ≅ΔRSQ                 SSS congruent

Answer:

a = 16/3 or 5 1/3 or 5.33...

Step-by-step explanation:

to find a you must first make all of the denominators the same

you must find 4 6 and 2s CGF

and that is 12

so multiply a/4 by 3/3 and get 3a/12

then multiply 5/6 by 2/2 and get 10/12

and lastly multiply 1/2 by 6/6 and get 6/12

at this point you can set the equation up like this

3a/12 - 10/12 = 6/12

but then you can multiply everything by 12

3a - 10 = 6

and then solve

add 10 to both sides

3a = 16

then divide 3 on each side

a = 16/3 or 5 1/3 or 5.33...

Answer:

Step-by-step explanation:

first term = a = 352

Common difference = d = second term - first term

                                  = 345 - 352

                                   = (-7)

nth term = a + (n-1)*d

43rd term = 352 + (43-1)*(-7)

                 = 352 + 42 *(-7)

                  = 352 - 294

                  = 58

Option A is correct because 0.14 represents that if a student is a 10th grader, there is a 14% chance he or she has a job.

It is given that there is a table with 4 columns and 3 rows.

It is a special type of frequency table that shows relationships between two categories.

From the attached table it is clear that 0.14 is the probability of getting a job if a student is a 10th grader,

Option B is incorrect, stating there is a 14% chance a student is a 10th grader if he/she has had a job because we do not know the number of students.

Option C is also incorrect stating that 14% of the students surveyed are 10th graders who have a job because we do not know the total number of students.

Option D is also incorrect because we do not know the number of students.

Therefore,Option A is correct because 0.14 represents that if a student is a 10th grader, there is a 14% chance he or she has a job.

Answer:

81 apples

Step-by-step explanation:

7 divided by 2 = 3.5

63 divided by 3.5 = 18

63 red + 18 green = 81 total apples

Answer:

81

Step-by-step explanation:

If we just divide 63 by 7 we can understand the value of the units used in the ratio

63/7 = 9

So that means the value of one unit on the ratio is 9

2*9 = 18 = amount of red apples

Answer:

£ 7.95

Step-by-step explanation:

Let the total money = £ x

Money spend on drinks and cake = 1.45 + 1.20 = £ 2.65

Money left with her = (2/3) of x

So, money spend = (1/3) of x

[tex]\dfrac{1}{3}*x= 2.65\\\\\\x=2.65*3\\\\[/tex]

x=30

Step-by-step explanation:

that's a 90º angle so 90÷3=30

You're looking for the smallest number that's a multiple of both 30 and 40.

If you've learned about "Least Common Multiple" by now, you'll be happy

to know that that's exactly what this is, (because when you were learning it,

you wondered what in the world you could ever use it for).  Well here you are.

The least common multiple of 30 and 40 is 120.

That's the 4th multiple of 30 and the 3rd multiple of 40.

If the trains are both in the station right now, then the next time they'll

both be here together will be 2 hours (120 minutes) from now.

And let me say in conclusion that when you ask for help with

a multiple-choice question, you must also post the choices that

you have.  It's not fair to the helper if he doesn't know the choices

The different probabilities and number of callers expected to be waiting are;

A) P(x = 3) = 0.0286

B) P(x = 13) = 0.1056

C) 8 will be waiting

D) P(x = 0) = 0.0003

E) P(x = 0) = 0.0067

We are given the rate of 48 phone calls per hour.

Thus, we will use poisson's distribution formula;

P(x) = (λˣ × e^(-λ))/x!

A) Probability of receiving three calls in a 10-minute interval of time which is P(x = 3). Thus;

λ = 48 * (10/60)

λ = 8

P(x = 3) = (8³ × e⁻⁸)/3!

P(x = 3) = 0.0286

B) Probability of receiving exactly 13 calls in 15 minutes is P(x = 13). Thus;

λ = 48 * (15/60)

λ = 12

P(x = 13) = (12¹³ × e⁻¹²)/13!

P(x = 13) = 0.1056

C) No calls are currently on hold and it takes 10 minutes to complete one call. Thus;

λ = 48 * (10/60)

λ = 8

Thus, 8 will be waiting after 10 minutes.

D) Probability that no one will be waiting is;

P(x = 0) = (8⁰ × e⁻⁸)/0!

P(x = 0) = 0.0003

E) No calls being processed and it takes 5 minutes for a personal time without being interrupted by a call. Thus;

λ = 48 * (5/60)

λ = 4

P(x = 0) = (4⁰ × e⁻⁵)/0!

P(x = 0) = 0.0067

Answer:

y = 156

Step-by-step explanation:

Solve for y:

y - 52 4 + 52 = 0

Multiply -52 and 4 together.

-52×4 = -208:

y + -208 + 52 = 0

Group like terms in y - 208 + 52.

Grouping like terms, y - 208 + 52 = y + (-208 + 52):

y + (-208 + 52) = 0

Evaluate 52 - 208.

52 - 208 = -156:

y + -156 = 0

Isolate terms with y to the left-hand side.

Add 156 to both sides:

y + (156 - 156) = 156

Hint: | Look for the difference of two identical terms.

156 - 156 = 0:
