What is Scale factor?To adjust the size of a figure without altering its shape, a scale factor is a number or conversion factor that is utilised. It is employed to change the size of an object. If the original figure's dimensions and the dilated (increased or lowered) figure's dimensions are known, the scale factor can be determined.
Gives:
We have area of each small square is 1 sq cm.
So, We have three grids a
For figure (i) there are 11 small square
So, Perimeter of the given figure =( 18 ×1)cm
=18 cm
For figure (ii) there are 13
Perimeter of the given figure =(28×1)cm
=28 cm
For figure (iii) there are 13
Perimeter of the given figure =(28×1)cm=28 cm.
=28 cm

Jim got 46 out of 60 correct on a test. What is the best estimate of the percent Jim got correct ?
Answers
Answer-
77
Step-by-step explanation:
i rounded 76.67% (which was the exact percentage of 46 out of 60)
2- 77%
Answer:
About 76.5% (77%)
Step-by-step explanation:
well start with the simple fractions. 40/60 is 2/3 which is 66.66666 repeating.
If we know it increased at least 5 more that is 45/60 which is 3/4, since 15 * 4 = 60, so 15 * 3 = 45.
We could say without getting too specific that every point will have about a 1.5 or more % increase since if it was out of 100 points every 1 question is +1 % and 50 points every question is +2 %. Since this is 60 it will be roughly about 1.6%
Ok the point is, about 76.5% (77%)

What is probability?Measure of the likelihood of an event happening is called Probability. Probability can be between 0 to 1. 0 means the event cannot happen, 1 indicates the specific event. The sum of the probabilities of all events in the sample space is 1.
Probability can be defined as the ratio between the number of favorable outcomes and the total number of outcomes of an event. For a trial with “n” number of results, the number of favorable outcomes can be denoted by x. The formula for calculating the probability of an event is as follows.
Probability (Event) = Favorable Outcome/Total Outcome = x/n
Given,
Number of questions = 40
One of 5 choices is correct
then, probability of getting correct option = 1/5
Number of correct answers = 40 × 1/5 = 8
Hence, 8 answers are expected to be correct.

The number of items sold over a four-month period are: month 1 2 3 4 sales 5100 5500 5400 5600 Calculate the forecasts for the 4th and 5th months using 3-month weighted moving average method with weights of 0.6 for the most recent month and 0.3 for the next to the most recent month. Further, suppose that the exponential smoothing constant α=0.5. Then calculate the forecasts for 3rd, 4th and 5th months, using exponential smoothing method. Under the 3-month weighted moving average method, what is the forecast for the fourth month?
Answers
Answer:
By using 3-month weighted moving average method -
Forecasts for the 4th month = 5400
Forecasts for the 5th month = 5530
By using Exponential smoothing method -
Forecasts for 3rd month = 5300
Forecast for 4th month = 5350
Forecast for 5th month = 5475
Step-by-step explanation:
To find - Calculate the forecasts for the 4th and 5th months using 3-month weighted moving average method.
Calculate the forecasts for 3rd, 4th and 5th months, using exponential smoothing method.
Proof -
Given that,
month 1 2 3 4
sales 5100 5500 5400 5600
F(4) = 0.6 A(3) + 0.3 A(2) + 0.1 A(1)
= 0.6 [ 5400] + 0.3 [ 5500] + 0.1 [ 5100]
= 3240 + 1650 + 510
= 5400
⇒forecasts for the 4th month = 5400
Now,
F(5) = 0.6 A(4) + 0.3 A(3) + 0.1 A(2)
= 0.6 [ 5600] + 0.3 [ 5400] + 0.1 [ 5500]
= 3360 + 1620 + 550
= 5530
⇒forecasts for the 5th month = 5530
Now,
Given that, the exponential smoothing constant α=0.5
Month Sales Forecast
1 5100 5100
2 5500 5100 + 0.5(5100 - 5100) = 5100
3 5400 5100 + 0.5(5500 - 5100) = 5300
4 5600 5300 + 0.5(5400 - 5300) = 5350
5 5350 + 0.5(5600 - 5350) = 5475
∴ we get
By using Exponential smoothing method -
Forecasts for 3rd month = 5300
Forecast for 4th month = 5350
Forecast for 5th month = 5475

1) A store sells small and large TV sets in the ratio 2:3. The total stock is 70
sets.1) How many small and large sets are in stock? 2)If the number of large
sets is increased by 8,what is the new ratio of small to big*
Answers
Answer:
(a)
[tex]Small = 28[/tex]
[tex]Large = 42[/tex]
(b)
[tex]Ratio = 14 : 25[/tex]
Step-by-step explanation:
Given
[tex]L = Large\\ S = Small[/tex]
[tex]S : L = 2 : 3[/tex]
[tex]Total = 70[/tex]
Solving (a): Number of each set.
The small set is calculated as:
[tex]Small = \frac{S}{S + T} * Total[/tex]
[tex]Small = \frac{2}{2+3} * 70[/tex]
[tex]Small = \frac{2}{5} * 70[/tex]
[tex]Small = 0.4 * 70[/tex]
[tex]Small = 28[/tex]
Using complement rule.
[tex]Large = Total - Small[/tex]
[tex]Large = 70 - 28[/tex]
[tex]Large = 42[/tex]
Solving (b): Increase large by 8.
The ratio is then calculated as:
[tex]Ratio = Small : Large + 8[/tex]
[tex]Ratio = 28 : 42 + 8[/tex]
[tex]Ratio = 28 : 50[/tex]
Divide by 2
[tex]Ratio = 14 : 25[/tex]
The length of a chord is 22 cm and that chord is 5 cm from the center of the circle. What is the length of the diameter ?
Answers
Answer:
The circle's diameter is approximately 24.2 cm
Step-by-step explanation:
You can use the Pythagorean theorem to solve this, my realising that the 5cm distance of the chord represends one side of a right triangle, half the chord's length is the other side, and the hypotenuse of the two is the circle's radius. With that we can say:
r = √(11² + 5²)
r = √(121 + 25)
r = √146
Now we can double that to get the diameter:
r = 2√146
r ≈ 24.2

then you would solve for x

Answer:

Step-by-step explanation:
Let's draw the center of the circle S and the segments SE and SD.
SE is perpendicular to EF (as EF is tangent to circle).
That means FED + DES = 90deg
We also know that DSE = 120deg
And because the SED is an isosceles triangle, we know that angle measures for DES and SDE are equal.
DES = (180deg - 120deg) / 2 = 30deg
FED = 90deg - DES = 90deg - 30deg = 60deg
