in the united states, about what percentage of people age 65 or older take at least five prescription medicines daily?

Answer:

between 10 and 12

Step-by-step explanation:

Given the measure of angles:

m∠B = 70°

m∠C = 60°

m∠A = 50°

Following this information, since the side lengths are directly proportional to the angle measure they see:

Angle B is the largest angle. Therefore, side AC is the longest side of the triangle since it is opposite of the largest angle.

Angle C is the smallest angle, so the side AB is the shortest side.

Therefore, side BC must be between 10 and 12 inches.

If emergency calls to a small municipality in Idaho come in at the rate of one every minute. A. Then the expected number of calls in one hour is 60 calls per hour, B. The probability of three calls in five minutes is approximately 0.1404, and C. The probability of no calls in a five-minute period is approximately 0.0067.

      The data given in the question is Emergency calls to a small municipality in Idaho come in at the rate of one every minute. So according to that, we have to find out:

A) Expected number of calls in one hour If emergency calls to a small   municipality in Idaho come in at the rate of one every minute, then in an hour, the number of calls is given by;

          Number of calls in 1 hour = Rate × Time= 1 × 60= 60

   Therefore, the expected number of calls in one hour is 60 calls.

B) Probability of three calls in five minutes using the Poisson distribution formula, we have P (x=3) = λx e^(-λ)/x!

        Where λ is the mean number of occurrences, x is the number

        of occurrences (in this case, 3), and e is

        the mathematical constant.

        P(x=3) = (1×5)^3 e^-(1×5)/3!

                   = 125e^-5/6 ≈ 0.1404 (to 4 decimals)

   Therefore, the probability of three calls in five minutes is approximately 0.1404.

C) Probability of no calls in a five-minute period using the Poisson  distribution formula,

       We have P(x=0) = λx e^(-λ)/x! Where λ is the mean

       number of occurrences, x is the number of occurrences (in

       this case, 0), and e is the mathematical constant.

                P(x=0) = (1×5)^0 e^- (1×5)/0!

                           = e^-5 ≈ 0.0067....... (to 4 decimals)

   Therefore, the probability of no calls in a five-minute period is approximately 0.0067.

Hi!

So let's start with some variables.

w is width

L is length.

The length is 4 less than 5 times the width. Let's put that into an equation.

L = 5w - 4

The perimeter is 76.

The perimeter is L + L + w + w or

perimeter = 2L + 2w.

Which means that 1/2 of the perimeter = L + w.

We know the perimeter is 76, so half of 76 is 38.

38 = L + W.

Let's put length in terms of width and plug in the previous equation.

38 = 5w - 4 + w

Add the same variables

38 = 6w - 4

simplify

42 = 6w

w = 7

And plug that into the length equation that we had above to get

L = 35 - 4

L = 31

The correct answer is C: 7, 31

Answer:

1. C. 7, 31 cm

2. A. 43°, 137°

Step-by-step explanation:

1.

A. 14+14+66+66=160 (incorrect)

B. 7+7+27+27= 68 (incorrect)

C. 7+7+31+31= 76 (correct)

D. 7+7+39+39= 92 (incorrect)

For this question, they give you a red herring. Since it's a multiple choice question, you can just add their length and width and see if they add up to 76. Only C. 7, 31 cm dimensions add up to have a perimeter of 76.

2.

Supplementary angles add up to 180°

The formula is x° × 5 = y° × 2 - 59

A. 43° × 5 = 137° × 2 - 59 (correct)

B. 41° × 5 ≠ 139° × 2 - 59 (incorrect)

C. 39° × 5 ≠ 141° × 2 - 59 (incorrect)

D. 37° × 5 ≠ 143° × 2 - 59 (incorrect)

For this question, you can't add up the angle measurements because they all equal 180°. Since it's a multiple choice question, you can just try them and see which one fits. Only A. 43°, 137° has angles that fit our formula.

Angel made 20% of his free throws over the season. If he shot 160 free throws, the number of throws he made can be calculated as follows:

Hence,

number of free throws made by Angel = 20% of 160

number of free throws made by Angel = 20 / 100 × 160

number of free throws made by Angel = 3200 / 100

Therefore,

number of free throws made by Angel = 32 throws

True. Selective distribution is a strategy in which a manufacturer limits the number of outlets at which its product is sold.

This strategy is often used for medium- and higher-priced products or stores that consumers don't expect to find on every street corner. By limiting the availability of the product, the manufacturer can maintain a premium image and prevent price erosion.

In contrast, products that are widely available and low-priced are more likely to be distributed through intensive distribution, in which the manufacturer tries to get the product into as many outlets as possible.

This strategy is effective for products with high turnover rates and where consumers prioritize convenience and accessibility over brand image.

The solutions to the equation 4x^2 - 20x + 25 = 10 are x = 5/2 and x = 3/2.

The equation 4x^2 - 20x + 25 = 10 can be rewritten as 4x^2 - 20x + 15 = 0. To find the solutions to this equation, we can factor it or use the quadratic formula.

The equation factors as (2x - 5)(2x - 3) = 0. Setting each factor equal to zero, we get 2x - 5 = 0 and 2x - 3 = 0. Solving these equations, we find x = 5/2 and x = 3/2.

Using the quadratic formula, which states that for an equation of the form ax^2 + bx + c = 0, the solutions are given by x = (-b ± sqrt(b^2 - 4ac)) / 2a, we can determine the solutions.

In this case, a = 4, b = -20, and c = 15. Substituting these values into the quadratic formula, we get x = (-(-20) ± sqrt((-20)^2 - 4 * 4 * 15)) / (2 * 4), which simplifies to x = (20 ± sqrt(400 - 240)) / 8.

Simplifying further, we have x = (20 ± sqrt(160)) / 8, which becomes x = (20 ± 4sqrt(10)) / 8. Finally, simplifying again, we obtain x = 5/2 ± sqrt(10)/2, which gives us the same solutions as before: x = 5/2 and x = 3/2.

Therefore, the solutions to the equation 4x^2 - 20x + 25 = 10 are x = 5/2 and x = 3/2.

To find the solutions to the equation, we can either factor it or use the quadratic formula. In this case, factoring and using the quadratic formula both yield the same solutions: x = 5/2 and x = 3/2. These values of x satisfy the equation 4x^2 - 20x + 25 = 10 when substituted back into the equation.

Answer:

u = 8

Step-by-step explanation:

calculate the slope of the line passing through the 2 give points using the slope formula, then equate to the given slope.

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (- 5, 5 ) and (x₂, y₂ ) = (5, u )

m = \(\frac{u-5}{5-(-5)}\) = \(\frac{u-5}{5+5}\) = \(\frac{u-5}{10}\) , then equating the 2 expressions gives

\(\frac{u-5}{10}\) = \(\frac{3}{10}\) ( cross- multiply )

10(u - 5) = 30 ( divide both sides by 10 )

u - 5 = 3 ( add 5 to both sides )

u = 8

Step-by-step explanation:

(u - 5)/(5 + 5)= 3/10

(u - 5)/10= 3/10

The minimum wage set by the government at $7.50 per hour does not result in a pay cut for unskilled workers, as it is below the equilibrium wage of $8.00 per hour.

The wage rate remains unchanged, and the labor market remains in balance.

The statement is false.

False.

The equilibrium wage in the market for unskilled labor is $8.00 per hour, which means that the market naturally sets the wage rate at this level, based on the forces of supply and demand.

The government then sets a minimum wage at $7.50 per hour.

Since the minimum wage is below the equilibrium wage, it does not directly impact the wage rate for unskilled workers.
The equilibrium wage represents the point at which the supply of labor (the number of workers willing to work at a given wage) equals the demand for labor (the number of workers that employers are willing to hire at a given wage).

In this case, both workers and employers are satisfied with the $8.00 per hour wage, and the labor market is balanced.
The government sets a minimum wage below the equilibrium wage, it essentially sets a wage floor that is not binding. Employers are still willing to pay the equilibrium wage of $8.00 per hour, and workers are still willing to accept this wage.

The wage for unskilled workers remains at $8.00 per hour, and there is no pay cut of 50 cents per hour.

Answer:

Initial amount = 8

Decay rate = 15%

Step-by-step explanation:

Given the exponential function :

y = 8(1 – 0.15)

The general form of an exponential Decay function is :

A = P(1 - r)^t

Where

A = final amout ; P = initial amount ; r = days cay rate ; t = time

Hence, comparing with the equation given :

P = 8 = initial amount

r = 0.15 = 0.15 * 100% = 15% = Decay rate

Solving a linear equation, we can see that you need to use 300 gallons of the 50% antifreeze.

We want to make a 40% antifreeze.

Let's define x as the number of gallons of the 50% antifreeze that we will use, and we will mix that with 100gal of 10% antifreeze, then the total volume  will be:

x + 100

And the concentration must be 40% (or 0.4 in decimal form), then the concentrations in the left must be the same as the one in the right:

x*0.5 + 100*0.1 = (x + 100)*0.4

This is just a linear equation that we can solve to find the value of x:

x*0.5 + 10 = x*0.4 + 40

x*0.5 - x*0.4 = 40 - 10

x*0.1 = 30

x = 30/0.1 = 300

This means that you need to use 300 gallons of the 50% antifreeze.

Answer:

Total cost of polishing the floor is Rs/500.

Step-by-step explanation:

The floor consists of 2000 tiles which have the shape of a rhombus.

Area of rhombus = \(\frac{d_{1} *d_{2} }{2}\)

Where: \(d_{1}\) and \(d_{2}\) are the diagonals.

Given that:

\(d_{1}\) = 40 cm = 0.4 m

\(d_{2}\) = 25 cm = 0.25 m

Then,

Area of each tile = \(\frac{0.4*0.25}{2}\)

                     = \(\frac{0.1}{2}\)

                     = 0.05 \(m^{2}\)

Area of each tile is 0.05 \(m^{2}\).

Since there are 2000 tiles on the floor of the building, then;

Total area covered by the tiles = 0.05 x 2000

                              = 100 \(m^{2}\)

The total cost of polishing the floor = 100 x Rs/5
