2000 grocery bags

Let x be the number of hours

If they're handing out 150 bags per hour, then 150x would be the amount given out in x hrs.

Since we want to get 950 bags left over a certain number of hrs, make this equation and solve:

950=2000-150x

150x=1050

In order to know if a triangle is a right triangle on a coordinate plane, you can find the lengths of all three sides of the triangle using the distance formula and apply the Pythagorean theorem.

Find the lengths of the three sides of the triangle using the distance formula.

Once you have the lengths of the sides, check if any of the three sides satisfy the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In other words, if a² + b² = c², where c is the longest side, then the triangle is a right triangle.

If one of the sides satisfies the Pythagorean theorem, then the triangle is a right triangle.

Step-by-step explanation:

Let us consider the breadth(B) of the rectangle to be x.

So now,

Length of Rectangle(L) = 2x-3

Perimeter of Rectangle = 2 (Length + Breadth) = 2(L+B)

So according to the question,

Perimeter = 2(L+B) = 24 feet

                     L + B   = 12 feet

                     2x - 3 + x = 12 feet

                     3x - 3 = 12 feet

                        3x = 12+3

                         x = 15/3

                          x = 5 feet = Breadth

So ,                   Length = 2x - 3 = 2x5 - 3 = 10 - 3 = 7 feet

Hence the length of the Rectangle is 7 feet.

The radius of the ball, to the nearest hundredth, is approximately 10.63 cm.

To find the radius of the spherical ball, we'll use the formula for the surface area of a sphere, which is given by:

Surface Area = 4πr²

Given that the surface area of the ball is 452 cm², we can set up the equation:

452 = 4πr²

Dividing both sides of the equation by 4π, we get:

113 = r²

Taking the square root of both sides, we find:

r ≈ √113

Evaluating √113 to the nearest hundredth, we have:

r ≈ 10.63 cm

Therefore, the radius of the ball, to the nearest hundredth, is approximately 10.63 cm.

268 +37 less than 346 makes a conjecture.  an argument to prove your conjecture is been made below using the  phrase  f A is less than B, and B is less than C, then A is less than C

My conjecture that 268 + 37 is less than 346. To prove this conjecture, I will use the mathematical phrase "If A is less than B, and B is less than C, then A is less than C". From this statement, we can see that if A is 268 and B is 37, we can say that 268 is less than 305 (268 + 37). We can also see that 305 is less than 346, so we can conclude that 268 + 37 is less than 346. To summarize, by using the mathematical phrase "If A is less than B, and B is less than C, then A is less than C", I have proven my conjecture that 268 + 37 is less than 346.

The link represented by function g multiplies the dependent variable by 9 for every increase of 2 units in the independent variable. The equation that represents g is \(g(x)= 2 \times3^x\),and the function has a value of 2 at 0

Let x be the independent variable, and let g(x) be the dependent variable.

According to the problem, for every 2 units the independent variable increases, the dependent variable is multiplied by 9. This suggests an exponential relationship of the form:

 \(g(x)= a \times b^x\)

where a is the initial value of the dependent variable (when x=0), and b is the growth factor (how much the dependent variable changes for every unit increase in x).

We are given that g(0) = 2, so we can plug in these values and solve for a:

 \(g(0)= a \times b^0\)

a = 2

So now we have:

\(g(x)= 2 \times b^x\)

We still need to find the growth factor b. We are told that the dependent variable is multiplied by 9 for every 2 units the independent variable increases. In other words:

\(g(x+2) = 9 \times g(x)\)

Using our equation for g(x), we can substitute in and simplify:

  \(2 \times b(x+2) = 9 \times 2\times b^x\)

Simplifying, we get:

\(b^2\) = 9

Taking the square root of both sides (we take the positive square root since b must be positive in order for g to be an increasing function), we get:

b = 3

So the final equation for g(x) is:

\(g(x) = 2 \times 3^x\)

Since the population increases at a rate proportional to the current number of people, the population will be three times of its initial population after 14.27 years.

The population of a community increases at a rate proportional to the number of people present at time t, means:

dP/dt = kP

where k is a constant.

Rearrange it:

(1/P) dP = k dt

Take the integral:

∫ (1/P) dP = ∫ k dt

ln P = kt + C, where C is a constant

Substitute t = 0, from the problem, it is known that P(t = 0) = P₀

Hence,

P(t) = P₀. e^(kt)

The population doubles after 9 years, means if we substitute t = 9

P(9) = P₀. e^(9k)

2P₀ = P₀. e^(9k)

2 = e^(9k)

Take the natural logarithmic:

ln 2 = 9k

k = (ln 2)/9 = 0.077

When the population grows to triple, it means P(t) = 3P₀

3P₀ = P₀. e^(kt)

ln 3 = kt

ln 3 = 0.077 t

t = (ln 3)/0.077 = 14.27 years.

Hence, the population will be three times of its initial population after 14.27 years.

Answer:

Step-by-step explanation:

Given the angles ∠ABF=8s-6, ∠ABE = 2(s + 11), we are to find the angle ∠EBF. The following expression is true for the three angles;

∠ABF = ∠ABE + ∠EBF

Substituting the given angles into the equation to get the unknown;

8s-6 = 2(s + 11)+ ∠EBF

open the parenthesis

8s-6 = 2s + 22+ ∠EBF

∠EBF = 8s-6-2s-22

collect the like terms

∠EBF = 8s-2s-22-6

∠EBF = 6s-28

factor out the common multiple

∠EBF = 2(3s-14)

Hence the measure of angle ∠EBF is 2(3s-14)

The 95% confident interval for the true mean length of stay of all hospital patients is (3.716, 5.284) days.

To find a 95% confident interval for the true mean length of stay of all hospital patients, we can use the formula:

Confidence interval = sample mean ± margin of error

The margin of error is calculated as the product of the critical value and the standard error, where the critical value is determined based on the desired confidence level and the standard error is the standard deviation divided by the square root of the sample size.

Given:

Sample mean  = 4.5 days

Standard deviation (σ) = 4 days

Sample size (n) = 100

Confidence level = 95%

First, let's calculate the critical value. Since the sample size is large (n > 30), we can use the Z-table to find the critical value for a 95% confidence level. The critical value corresponds to a 2-tailed test, so we need to find the value that leaves 2.5% in each tail.

Looking up the Z-table, the critical value for a 95% confidence level is approximately 1.96.

Next, let's calculate the standard error:

Standard error (SE) = σ / sqrt(n)

SE = 4 / sqrt(100)

SE = 4 / 10

SE = 0.4

Now, we can calculate the margin of error:

Margin of error = critical value * standard error

Margin of error = 1.96 * 0.4

Margin of error = 0.784

Finally, we can construct the confidence interval:

Confidence interval = sample mean ± margin of error

Confidence interval = 4.5 ± 0.784

Confidence interval = (3.716, 5.284)

To calculate the increase in range when the number 1 replaces the number 4 in the set {2, 4, 5, 5, 7, 6, 8, 5}, we need to first find the range of the original set and then find the range of the modified set.

The range of a set of numbers is the difference between the maximum and minimum values in the set.

Original set: {2, 4, 5, 5, 7, 6, 8, 5}

Maximum value: 8

Minimum value: 2

Range of the original set: 8 - 2 = 6

Modified set (with 1 replacing 4): {2, 1, 5, 5, 7, 6, 8, 5}

Maximum value: 8

Minimum value: 1

Range of the modified set: 8 - 1 = 7
