Answer:
y = x/3 - 5
Step-by-step explanation:
Answer:
y = (1/3)x - 5 .
Step-by-step explanation:
(-6 , -7) ; (3 ,-4)
Slope = \(\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\)
\(=\frac{-4-[-7]}{3-[-6]}\\\\= \frac{-4 + 7}{3+6}\\\\= \frac{3}{9}\\\\=\frac{1}{3}\)
m = 1/3 ; (3,-4)
y - y1 = m(x - x1)
\(y - [-4]=\frac{1}{3}(x-3)\\\\y + 4 = \frac{1}{3}x-3*\frac{1}{3}\\\\y + 4 = \frac{1}{3}x-1\\\\y =\frac{1}{3}x-1-4\\\\y = \frac{1}{3}x - 5\)
It is believed that nearsightedness affects about 12% of all children. A kindergarten has registered 198 incoming children. Complete parts a) through c). a) Can the central limit theorem be applied to describe the sampling distribution for the sample proportion of children who are nearsighted? Check the conditions and discuss any assumptions you need to make.
Answer:
As the sample size is large enough, i.e. n = 198 > 30 the central limit theorem can be applied to describe the sampling distribution for the sample proportion of children who are nearsighted.
Step-by-step explanation:
Let the random variable p denote the proportion of children affected by nearsightedness.
The previously known proportion was, p = 0.12.
A random sample of n = 198 children are selected.
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
\(\mu_{\hat p}=p\)
The standard deviation of this sampling distribution of sample proportion is:
\(\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}\)
As the sample size is large enough, i.e. n = 198 > 30 the central limit theorem can be applied to describe the sampling distribution for the sample proportion of children who are nearsighted.

Step-by-step explanation:
Imagine that you need to buy some chicken for dinner tonight. You found an ad showing that the store across town has chicken on sale for $1.59 a pound. Your usual neighborhood store sells the same chicken for $2.89 a pound. Is it worth the extra drive?
Look at the information below you’ll need to solve the problem.
How much chicken will you be buying? 3 pounds
How does the distance and the time it takes to get there, compare between the two stores? Your neighborhood store is 2.1 miles away, and takes about 8 minutes. The store across town is 8.6 miles away, and takes about 24 minutes.
What kind of mileage does your car get? It averages about 22 miles per gallon in the city.
How many gallons of fuel does your car hold? About 13 gallons
How much is gas? About $1.98/gallon right now.
Are there any other pieces of information you need to solve the problem? Which option would you choose? Is going to the further store cheaper? Or is going to the close store cheaper? How much money does the cheaper option save you? Give your answer to the nearest cent.
Answer:
Step-by-step explanation:
Considering the store in your neighborhood, price per pound of chicken is $2.89. The cost of 3 pounds is
3 × 2.89 = $8.67
Distance = 2.1 miles
The car averages about 22 miles per gallon in the city. It means that the number of gallons needed is
2.1/22 = 0.095 gallons
Cost of gas = $1.98/gallon
Cost of 0.095 gallons =
1.98 × 0.095 = $0.1881
Total cost = 8.67 + 0.1881 = $8.86
Considering the store across town, price per pound of chicken is $1.59. The cost of 3 pounds is
3 × 1.59 = $4.77
Distance = 8.6 miles
The car averages about 22 miles per gallon in the city. It means that the number of gallons needed is
8.6/22 = 0.39 gallons
Cost of gas = $1.98/gallon
Cost of 0.39 gallons =
1.98 × 0.39 = $0.77
Total cost = 4.77 + 0.77 = $5.54
Therefore, it is cheaper going to the further store. The amount that the cheaper option saves is
8.86 - 5.54 = $3.32

The algorithm/abstract strategy to justify the fraction 3/5 involves interpreting it as a division, performing the division, and obtaining the decimal representation as the results.
To justify the fraction 3/5, we can use the concept of division and understand it as a ratio or proportion.
Algorithm/Abstract Strategy:
Start with the numerator, which is 3.
Identify the denominator, which is 5.
Interpret the fraction as a ratio or comparison between the numerator and denominator.
Understand that 3/5 represents a division where the numerator (3) is divided by the denominator (5).
Perform the division: 3 ÷ 5.
Simplify the division to its simplest form, if necessary.
The result of the division, in this case, is the decimal representation of the fraction.

A garden is to designed with a rectangular part in the middle with two semi-circles on the ends.
The dimensions of the rectangular portion are 18.4 feet long and 8.6 feet wide.
a) What is the area of one semi-circle at one end?
b) What is the area of the garden?
c) Find the area in square metres.
Given statement solution is :- a) The area of one semi-circle at one end is 58.09 square feet.
b) The area of the garden is 274.42 square feet.
c) The area in square metres is approximately 58.09 square feet.
The area of the garden is approximately 274.42 square feet, and the area in square meters is approximately 25.49 square meters.
a) To find the area of one semi-circle at one end, we need to calculate the area of a complete circle and then divide it by 2. The formula for the area of a circle is A = πr², where A represents the area and r is the radius.
Since the diameter of the semi-circle is equal to the width of the rectangular portion, which is 8.6 feet, the radius will be half of that, which is 8.6 / 2 = 4.3 feet.
Now we can calculate the area of the semi-circle:
A = (π * 4.3²) / 2
A ≈ 58.09 square feet
b) To find the area of the garden, we need to sum the area of the rectangular portion with the areas of the two semi-circles.
Area of the rectangular portion = length * width
Area of the rectangular portion = 18.4 feet * 8.6 feet
Area of the rectangular portion ≈ 158.24 square feet
Area of the two semi-circles = 2 * (area of one semi-circle)
Area of the two semi-circles ≈ 2 * 58.09 square feet
Area of the two semi-circles ≈ 116.18 square feet
Total area of the garden = area of the rectangular portion + area of the two semi-circles
Total area of the garden ≈ 158.24 square feet + 116.18 square feet
Total area of the garden ≈ 274.42 square feet
c) To convert the area from square feet to square meters, we need to know the conversion factor. Since 1 foot is approximately 0.3048 meters, we can use this conversion factor to convert the area.
Area in square meters = Total area of the garden * (0.3048)²
Area in square meters ≈ 274.42 square feet * 0.3048²
Area in square meters ≈ 25.49 square meters
Therefore, the area of one semi-circle at one end is approximately 58.09 square feet. The area of the garden is approximately 274.42 square feet, and the area in square meters is approximately 25.49 square meters.

Answer:
10iStep-by-step explanation:
8-7=1
7-6=1
The real part of the complex numbers is following an arithmetic progression with first term 8 and common difference 1.
………………………………………
-6+2=-4
-4+2=-2
THe Imaginary part of the complex numbers is following an arithmetic progression with first term -6 and common difference 2.
