Answer:
advertising cost would be $2010
Step-by-step explanation:
y = 10000(5) + 10
y = 2000 + 10
y = 2010
Answer:
$2010
Step-by-step explanation:
Let x = 10,000
[tex]y = \frac{10,000}{5}+10\\y=2000+10\\y=2010[/tex]
Therefore, the predicted advertisement costs for selling 10,000 books is $2010.

Answer:
question 8
Step-by-step explanation:
y = 4
2x + 3y = 22
put y = 4 into equation 2
2x + 3 ( 4) = 22
2x + 12 = 22
2x = 22 - 12
2x = 10
x = 5
therefore x = 5 and y = 4

A car covers a distance of 66.7 km in 1 litre of petrol .How much distance will it cover in 10 litre of
petrol ?
Answers
Answer:
666.7
Step-by-step explanation:
66.7*10=666.7
the reason its not 667 is beacuse of the repeateing rule like 1/3 is .33333
and 2/3 is .66667 the reason there is a 7 at the end is becuse you round up so i doesn't run on forever
Answer:
667 km
Step-by-step explanation:
66.7 km / 1 liter
Y = 66.7x
X = Liters of Petrol
Y = Total KM Traveled
Y = 66.7 (10)
Y = 667km
An experiment to investigate the survival time in hours of an electronic component consists of placing the parts in a test cell and running them under elevated temperature conditions. Six samples were tested with the following resulting failure times (in hours): 34, 40, 46, 49, 61, 64. (a)Calculate the sample mean and sample standard deviation of the failure time.
Answers
Answer:
The sample mean of failure time was of 49 hours.
The standard deviation of the failure time was of 11.7 hours.
Step-by-step explanation:
Sample mean:
Sum of all values divided by the number of values. So
[tex]\overline{x} = \frac{34+40+46+49+61+64}{6} = 49[/tex]
The sample mean of failure time was of 49 hours.
Standard deviation:
Square root of the division between the sum of the differences squared betweene each value and the mean, divided by the sample size subtracted by 1. So
[tex]s = \sqrt{\frac{(34-49)^2+(40-49)^2+(46-49)^2+(49-49)^2+(61-49)^2+(64-49)^2}{5}} = 11.7[/tex]
The standard deviation of the failure time was of 11.7 hours.
If the Circumstance of wobble ball is 242cm what is the surface area?
Answers
Answer:
1,166 is the SA
correct me if im wrong somehow
Step-by-step explanation:
a wobble ball is a sphere
circumference=8(pi)
242=8(3.14)
so 242 divided by 25.12
this ends up with 9.633757961783439, which is the radius of the circumference
SA of a sphere= 4(pi)r²
SA=4(3.14)9.633757961783439²
SA=4(3.14)92.80929246622581
SA=1,165.684713375796

At the beginning of a basketball season the Panthers won40 games out of 17 games at this rate how many games will they win in a normal 120 game season
Answers
Answer:
51
Step-by-step explanation:
The problem states "the Panthers won 40 games out of 17 games"
It is impossible to win more games than the number of games.
Perhaps the problem should state "the Panthers won 17 games out of 40 games"
If this is correct, then we can answer the question with a proportion.
17 wins is to 40 games as x wins is to 120 games
17/40 = x/120
40 * x = 17 * 120
Divide both sides by 40.
x = 17 * 3
x = 51

In a recent survey of 655 working Americans ages 25-34, the average weekly amount spent on lunch was 43.76 with standard deviation 2.67. The weekly amounts are approximately bell-shaped. (c) Between what two values will approximately 95% of the amounts be?
Answers
Answer:
Between 38.42 and 49.1.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 43.76, standard deviation of 2.67.
Between what two values will approximately 95% of the amounts be?
By the Empirical Rule, within 2 standard deviations of the mean. So
43.76 - 2*2.67 = 38.42
43.76 + 2*2.67 = 49.1
Between 38.42 and 49.1.
A researcher’s garden contains 90 sweet pea plants,
which have either white or purple flowers. About 70 of the plants have purple flowers, and about 20 have white flowers.
Would you expect that one plant randomly selected from the garden will have purple or white
flowers? Explain
Answers
Hey buddy I am here to help!
No, because according to theoretically probability most of the sweet pea plants have purple flowers causing that one plant to have the probability purple flowers more than of the white flowers!
Here is teh mathematical way-
total plants = 90
purple flowers = 70
white flowers = 20
higher probability of flower = 70/90

Answer:
A. 17.5 miles
Step-by-step explanation:
Your knowledge of triangles tells you the hypotenuse is longer than the long leg of the triangle, and is shorter than than the sum of the two legs. This means the difference between Michael's distance and Leah's distance will be strictly less than 25 miles.
The only answer choice in that range is 17.5 miles.
__
If you want to do the math, you can find Michael's distance to be ...
38 +25 = 63 miles.
Leah's distance will be ...
√(38² +25²) = √2069 ≈ 45.5 miles.
Then Michael's excess distance is ...
63 -45.5 = 17.5 miles

Step-by-step explanation:
In order to solve this, we need to know that there is 360° in a full circle. Knowing this, we can make the following equation from the diagram provided...
60° + 130° + x° = 360
x° = 360° - 60° - 130°

We have defined g(x) = x^3+x+3, the function we want the zero of. We have defined the iteration function to be f(x).

Modern graphing calculators not only make the iteration trivially simple, they also give a first approximation good to 2 or 3 decimal places in many cases.
