Answer:
To construct a 98% confidence interval with a maximum error of 0.09 pounds and assuming a variance of 1 pound, the minimum sample size can be calculated using the formula:
n = (2 * standard error of the mean / margin of error)^2
Plugging in the values, we get:
n = (2 * (1 / sqrt(n)) / 0.09)^2
Solving for n, we get n = 832.6. Rounding up to the next integer, the minimum number of males over age 27 they must include in their sample is 833.

A culture of bacteria has an initial population of 7100 bacteria and doubles every 2 hours. Using the formula P_t = P_0\cdot 2^{\frac{t}{d}}P t =P 0 ⋅2 d t , where P_tP t is the population after t hours, P_0P 0 is the initial population, t is the time in hours and d is the doubling time, what is the population of bacteria in the culture after 15 hours, to the nearest whole number?
The population of bacteria in the culture after 15 hours, to the nearest whole number would be 1285235
A culture of bacteria has an initial population of 7100 bacteria and doubles every 2 hours.
Given that,
P_t = P_0 * 2^(t/d) , which refers to the formula for the calculation of the number of bacterial cell in a population.
In the given formula, P_t is the population after t hours, P_0 is the initial population, t is the time in hours and d is the doubling time in hours,
Therefore,
P_0 = 7100
d = 2
t = 15
so,
P_15 = 7100 * 2^(15/2) = 7100 * 181.019= 1285234.9 which is nearly equal to 1285235

What is a 2 step problem?
A 2-step problem is a mathematical problem that can be solved using two steps or operations. These types of problems are typically simple and can be solved using basic arithmetic or algebraic concepts.
For example, a 2-step problem could involve solving for one variable in one equation and then substituting that value into another equation to find the value of a second variable.
For example:
2x+3y=10 and 3x-2y=5
Here, first step would be to solve for x in the first equation by isolating x and in the second step we can substitute that value of x in the second equation to solve for y.
It can also refer to a problem that can be solved in two steps by breaking the problem down into simpler parts. For example, a 2-step problem in geometry could involve finding the area of a shape by first finding the area of one part of the shape and then adding that to the area of another part of the shape.
In general, 2-step problems are not complex and can be solved easily by breaking down the problem into simpler parts and solving each part separately.

What is factor?A number that divides another number by itself with no residual is known as a factor. In other words, if multiplying two whole numbers results in the creation of a product, the numbers we are multiplying are factors of the product since the product is divisible by them. Division and multiplication are the two ways to discover factors. A number or other mathematical object is factorized or factored in mathematics by expressing it as the product of numerous factors, often smaller or simpler things of the same sort.

find the number that makes the ratio equivalent to 1:8
Answer:
2:16
Step-by-step explanation:
maybe i don't know im not smart but that is the ratio equalivent i guess i have to make this 20 words long soooo
Answer:
To find the number that makes the ratio equivalent to 1:8, we need to set up the ratio as a fraction and solve for the missing value.
The ratio 1:8 can be written as the fraction 1/8. In this case, the missing value is the numerator (1) and the known value is the denominator (8). To solve for the missing value, we can multiply both the numerator and denominator by the same value.
For example, if we multiply both the numerator and denominator by 2, we have:
1/8 = (12)/(82) = 2/16
If we multiply both the numerator and denominator by 4, we have:
1/8 = (14)/(84) = 4/32
If we multiply both the numerator and denominator by 5, we have:
1/8 = (15)/(85) = 5/40
In each of these cases, the ratio is still equivalent to 1:8, but the missing value (the numerator) is different. In general, we can multiply the numerator and denominator by any value to find the missing number that makes the ratio equivalent to 1:8.
For example, if we multiply both the numerator and denominator by 10, we have:
1/8 = (110)/(810) = 10/80
In this case, the missing value (the numerator) is 10, which makes the ratio equivalent to 1:8.

Homer Simpson left an estate of $2.4 million. He left 10% to Springfield University, 15% to the First Church of Springfield, $600,000 to his wife Marge, and the remainder to be divided among his three children. How much did each child receive?
Hello there!
Answer:
$400'000
Step-by-step explanation:
Estate -- $2.4 million or $2'400'000
Springfield University will receive: 10% * $2'400'000 = 0.1 * $2'400'000 = $240'000
First Church of Springfield will receive: 15% * $2'400'000 = 0.15 * $2'400'000 = $360'000
Wife will receive $600'000
Total: $240'000 + $360'000 + $600'000 = $1'200'000
Children will receive at total: $2'400'000 - $1'200'000 = $1'200'000
So each child will receive: $1'200'000 / 3 = $400'000
Answer: Each child of Homer Simpson gets $400000.
Step-by-step explanation:
Homer Simpson left 10% of his estate, or (10/100) x $2.4 million
= $ (10/100)x2400000= $240000
$240,000 to Springfield University.
He left 15% of his estate, or (15/100) x $2.4 million = $(15/100)2400000
= $360000
So 360,000 to the First Church of Springfield.
So in total, he left $240,000 + $360,000 + $600,000 = $(240000+360000+600000)
=$1200000
$1,200,000 to organizations and his wife.
That means the remainder of the estate, $2.4 million - $1,200,000
= $2400000-1200000
= $1200000
1,200,000, was divided among his three children. So each child received $1,200,000 / 3 = $1200000/3
=$400000
Answer: $400000.

It takes 126 cubes that have edge lengths of 1/3 ft to completely fill a plastic bin. What is the area of the base of the bin?
The area of the base of the bin is 9 ft^2.
The given information states that the bin is filled with 126 cubes that have edge lengths of 1/3 ft. To determine the area of the base of the bin, we must first determine the total volume of the bin.
Since each cube has a volume of 1/27 ft^3, the total volume of the bin is 126/27 ft^3. Since the volume of a rectangular prism is equal to the length times the width times the height, we can solve for the area of the base of the bin by rearranging the formula to A = V/h, where A is the area, V is the volume, and h is the height.
We can substitute the values given to obtain A = 126/27 ft^3/h. Since the height of the bin is equal to the edge length of the cubes, which is 1/3 ft, we can substitute that value into the equation to get A = 126/27 ft^3/1/3 ft = 9 ft^2. Therefore, the area of the base of the bin is 9 ft^2.

Amrita divides a circular disc of radius 7 cm in two equal parts. What is the perimeter of each semicircular shape disc? (USE π=22/7 )
The perimeter of each semicircular shape disc created by Amrita by dividing a circular disc of radius 7 cm into two equal parts is 44 cm. This is calculated by multiplying the circumference of the circle (2πr = 2 × 22/7 × 7 = 44 cm) by half.
Amrita divided a circular disc of radius 7 cm into two equal parts. This created two semicircular shape discs
Step 1: Calculate the circumference of the original circle.
Circumference of a circle = 2πr
Circumference of the circle with a radius of
7 cm = 2πr = 2 × 22/7 × 7 = 44 cm
Step 2: Calculate the perimeter of each semicircular shape disc.
The semicircular shape discs are created by dividing the original disc into two equal parts. Therefore, the perimeter of each semicircular shape disc is half of the circumference of the original circle.
