a scientist recorded the number of geese found in park on various days of week the data are shown below
6,9,,2,12,3,5,9 what is the range of these data

Rounding up to the nearest whole number, we would need a sample size of at least 105 businesses to construct a 99% confidence interval with a 4% margin of error.

To determine the sample size required to construct a 99% confidence interval for the proportion of businesses with a 4% margin of error, we need to use the formula:

n = (Z^2 * p * (1-p)) / E^2

Where:

n = sample size

Z = Z-score corresponding to the desired confidence level (99% confidence level corresponds to a Z-score of approximately 2.576)

p = estimated proportion (since we don't have an estimate, we can assume p = 0.5 to get a conservative estimate)

E = margin of error (0.04 or 4%)

Plugging in the values, we have:

n = (2.576^2 * 0.5 * (1-0.5)) / 0.04^2

n = (6.638176 * 0.25) / 0.0016

n ≈ 104.364

84 Customers

Step-by-step explanation:

To predict how many customers out of the 350 will buy two or more pairs, you need to find 24% of the 350 customers: 24% * 350 = 84 Customers.

Using the binomial distribution, it is found that there is a 0.1111 = 11.11% probability that a certain crate has more than 4 contaminated chickens.

For each chicken, there are only two possible outcomes, either they are contaminated, or they are not. The chickens are independently selected, hence, the binomial distribution is used.

The formula is:

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

The parameters are:

In this problem:

The probability that a certain crate has more than 4 contaminated chickens is:

\(P(X > 4) = 1 - P(X \leq 4)\)

In which:

\(P(X \leq 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)\)

Then

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 0) = C_{24,0}.(0.3)^{0}.(0.7)^{24} = 0.0002\)

\(P(X = 1) = C_{24,1}.(0.3)^{1}.(0.7)^{23} = 0.0020\)

\(P(X = 2) = C_{24,2}.(0.3)^{2}.(0.7)^{22} = 0.0097\)

\(P(X = 3) = C_{24,3}.(0.3)^{3}.(0.7)^{21} = 0.0305\)

\(P(X = 4) = C_{24,4}.(0.3)^{4}.(0.7)^{20} = 0.0687\)

Hence

\(P(X \leq 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) = 0.0002 + 0.0020 + 0.0097 + 0.0305 + 0.0687 = 0.1111\)

0.1111 = 11.11% probability that a certain crate has more than 4 contaminated chickens.

Answer:

12 hours

Step-by-step explanation:

Let x hours be the time it will take you to mow the greens at the golf course.

Since Kim can mow twice as fast, it will take Kim x / 2 hours to mow the greens.

In 1 hour, you will mow 1 / x of the greens

in 1 hour, Kim will mow 1 / (x / 2) of the greens= 2 / x of the greens

In 4 hours, you will mow 4 * 1 / x of the course = 4 / x of the greens

In 4 hours, Kim will mow 4 * 1 / (x / 2) of the course = 4 / (x / 2) = 8 / x of the greens.

Since we are dealing in fraction, the sum of the amount of greens that they would individually mow in 4 hours should be 1. i.e

(4 / x) + (8 / x) = 1

12 / x = 1

Solve for x;

x = 12

Therefore, it will take you 12 hours to mow the greens alone.

Answer:

They sold 175 small popcorns and 103 Large popcorns

Step-by-step explanation:

The equation is

L + S = 278 this means the total large and small popcorn that they sold is 278

3L+1S= 484  The owner of the question told me the total profit is 484

When we solve we can turn the first equation into L=-S+278

we substitute  L=-S+278 into 3L+1S=484 we get  -3S+ 834+ S= 484

-3S+834+1S=484

-2S+ 834= 484

-2S=- 350

2s= 350

s= 175

We know that they sold 175 small popcorns now. Now we Substitute 175 into L+ S= 278 and get L+ 175=278

L+175=278

L= 103

They sold 175 small popcorns and 103 Large popcorns

An equation is an expression composed of variables and numbers linked together by mathematical operations.

Let x represent the horizontal distance traveled by the ball and h represent the height of the ball. Given that:

h = -0.01x² + 1.18x + 2

The ball hits the ground when h = 0, hence:

-0.01x² + 1.18x + 2 = 0

x = 119.67

Answer:

2 Blueberry scones and 5 Raspberry scones

Step-by-step explanation:

Given:

34 Blueberry scones

85 raspberry scones

17 Bags to fit scones

34 Blueberry so 34 divided by the Bag 17 (34 ÷ 17 = 2)

85 Raspberry scones so 85 divided by the Bag 17 ( 84 ÷ 17 = 5)

Therefore Jason can put 2 Blueberry scones and 5 Raspberry scones in each Bag

a) Since the triangles are congruent, and ΔABC is congruent to ΔDEF, segments AB and DE have the same value. Therefore, you can use algebra to solve for x when using the knowledge that (12 - 4x) is equal to (15 - 3x).

To solve:

12 - 4x = 15 - 3x

12 = 15 + x

-3 = x

Therefore, x is equal to -3.

b) To find the value of AB, plug in the value of x found in part a).

12 - 4x

12 - 4(-3)

12 - (-12)

12 + 12 = 24

Thus, segment AB is equal to 24.

c) As shown in part b), plug in the value of x found in part a) to find the value of segment DE.

15 - 3x

15 - 3(-3)

15 - (-9)

15 + 9 = 24

Thus, segment DE is also equal to 24.

We can confirm the knowledge of the equal side lengths because the triangle are congruent. This means that all the side lengths in the triangle are the same, which is confirmed when algebraically plugging in the value of x to solve for the values of the segments AB and DE.

Answer:

8 and 6

Step-by-step explanation:

If you use x for the first number, and y for the second, you get equations of 3x+5y=54 and x-2=y.

You can substitute the second equation into the first one to solve it. This gives 3x+5(x-2)=54.

The brackets can be expanded to 3x+5x-10=54. Collecting like terms makes it 8x-10=54.

Next, we add 10 to both sides. This gives 8x=64.

From there, we isolate the x by dividing both sides by 8, giving x=8.

To work out the second number, we can sub 8 for x in either equation (I'm using the second one as it's simpler).

This comes to y=8-2, therefore y=6.
