units in the drawing.
Scale:
10 cm
length
A
What is the length, in cm, of the actual hotdog?
cm
The length of the actual hotdog comes to be 15cms.
What is a scale factor?A scale factor is a ratio between corresponding measurements of an object and a representation of that object.
From the diagram
6 units = 10cm
So, 1 unit =10/6 cm
The length of the hotdog shown in the graph = 9 units
So, 9 units = 9*(10/6)
9 units = 15cms
So, the actual length of the hotdog =15cms
Thus, the length of the actual hotdog comes to be 15cms.

A car and a bus which are 280 miles apart are driving towards each other. The car is moving at 50 mph while the bus is moving at 55 mph. How long will it take them to meet?
Answer:
2.6667 hours
Step-by-step explanation:
Given that:
Distance between car and bus = 280 miles apart
What le moving towards each other ;
Speed of car = 55 mph
Speed of bus = 50 mph
Time it will take them to meet;
Time = distance / speed
Hence :
Total distance to be covered = 280 miles
Total speed = (55mph + 50 mph) = 105 mph
Hence ,
Time = 280 miles / 105 mph
Time = 2.667 hours

Find the next term of the square 16,9,2,-5....
Answer:
- 12
Step-by-step explanation:
There is a common difference between consecutive terms in the sequence.
9 - 16 = 2 - 9 = - 5 - 2 = - 7
Thus to find the next term subtract 7 from the previous term, that is
- 5 - 7 = - 12

You operate a fresh fruit and vegetable market. For normal shipments, about 9.0% of the peaches are spoiled when they reached your market. You anticipate a busy weekend and would like to have 100 pounds of peaches to sell. To have 100 pounds of peaches and considering the spoilage rate, how many pounds should you order?
Answer:
110 pounds of peaches should be ordered
Step-by-step explanation:
Here, we want to calculate the number of pounds of peaches to order.
Let the number of peaches to ordered be x peaches
Now, since 9% is expected to be bad, then the percentage expected to be good will be 91%
Thus;
91% of x = 100
91/100 * x = 100
91x = 100 * 100
x = 10000/91
x = 109.89
Since we cannot have fractional peaches, then x must be 110

A 12 m object is represented in a picture as being 2 cm. What is the scale?
Answer: 1:600
Step-by-step explanation:
From the question, we are informed that 12 m object is represented in a picture as being 2 cm.
To find the scale used, we needed to convert 12m to cm. Since 100cm = 1m, then 12m = 12 × 100 = 1200cm.
Therefore, a 1200cm object is represented in a picture as being 2 cm. The scale will be:
= 2/1200
= 1/600
= 1:600
This means that 1 centimeter in the picture represent 600 centimeter or 6 meters.

In February of 2012, a sample of adults showed indicating that their financial security was more than fair. In February of 2010, a sample of adults showed indicating that their financial security was more than fair. a. State the hypotheses that can be used to test for a significant difference between the population proportions for the two years.\
Complete Question
Country financials, a financial services company, uses surveys of adults age 18 and older to determine if personal financial fitness is changing over time. In February 2012, a sample of 1000 adults showed 410 indicating that their financial security was more that fair. In Feb 2010, a sample of 900 adults showed 315 indicating that their financial security was more than fair.
a
State the hypotheses that can be used to test for a significant difference between the population proportions for the two years.
b
What is the sample proportion indicating that their financial security was more that fair in 2012?In 2010?
c
Conduct the hypothesis test and compute the p-value.At a .05 level of significance what is your conclusion?
Answer:
a
The null hypothesis is [tex]H_o : p_1 = p_2[/tex]
The alternative hypothesis is [tex]H_a : p_1 \ne p_2[/tex]
b
in 2012 [tex]\r p_1 =0.41[/tex]
in 2010 [tex]\r p_2 =0.35[/tex]
c
The p-value is [tex]p-value = 0.0072 [/tex]
The conclusion is
There is sufficient evidence to conclude that the proportion of those indicating that financial security is more fair in Feb 2010 is different from the proportion of those indicating that financial security is more fair in Feb 2012.
Step-by-step explanation:
From the question we are told that
The sample size in 2012 is [tex]n_1 = 1000[/tex]
The number that indicated that their finance was more than fail is k = 410
The sample size in 2010 is [tex]n_2 = 900[/tex]
The number that indicated that their finance was more than fail is u = 315
The level of significance is [tex] \alpha = 0.05[/ex]
The null hypothesis is [tex]H_o : p_1 = p_2[/tex]
The alternative hypothesis is [tex]H_a : p_1 \ne p_2[/tex]
Generally the sample proportion for 2012 is mathematically represented as
[tex]\r p_1 = \frac{k}{n_1}[/tex]
=> [tex]\r p_1 = \frac{410}{1000}[/tex]
=> [tex]\r p_1 =0.41[/tex]
Generally the sample proportion for 2010 is mathematically represented as
[tex]\r p_2 = \frac{u}{n_2}[/tex]
=> [tex]\r p_2 = \frac{315}{900}[/tex]
=> [tex]\r p_2 =0.35[/tex]
Generally the pooled sample proportion is mathematically represented as
[tex]\r p = \frac{k + u }{n_1 + n_2}[/tex]
=> [tex]\r p = \frac{410 + 315 }{1000+ 900}[/tex]
=> [tex]\r p = 0.3816 [/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{( \r p_1 - \r p_2 ) - 0}{\sqrt{\r p (1 - \r p ) ( \frac{1}{n_1} +\frac{1}{n_2} )} }[/tex]
[tex]z = \frac{( 0.41 -0.35 ) - 0}{\sqrt{0.3816 (1 - 0.3816 ) ( \frac{1}{1000} +\frac{1}{900} )} }[/tex]
[tex]z = \frac{( 0.41 -0.35 ) - 0}{\sqrt{0.3816 (1 - 0.3816 ) ( \frac{1}{1000} +\frac{1}{900} )} }[/tex]
[tex]z = 2.688[/tex]
Generally the p- value is mathematically represented as
[tex]p-value = 2 P(Z >2.688 )[/tex]
From the z -table
[tex]P(Z > 2.688) = 0.0036 [/tex]
So
[tex]p-value = 2 *0.0036 [/tex]
[tex]p-value = 0.0072 [/tex]
So from the p-value obtained we see that p-value < [tex]\alpha[/tex] so we reject the null hypothesis
Thus there is sufficient evidence to conclude that the proportion of financial security is more fair in Feb 2010 is different from the proportion of financial security is more fair in Feb 2012.
