No, because to get the mean you have to add up all the numbers and then divide by how many numbers there are which will not be more than the greatest number.

In one week the owner of Carly's Coffeehouse found that the number of orders for bagels was 2/3 the number of orders for chocola
Novosadov [1.4K]

Answer:

  210

Step-by-step explanation:

We can write the ratio as ...

  bagels : scones = 2 : 3

Then bagels are 2/(2+3) = 2/5 of the total.

  # bagels = (2/5)(525)

  # bagels = 210

Find the times (to the nearest hundredth of a second) that the weight is halfway to its maximum negative position over the inter
hoa [83]

Answer:

0.20 and 0.36

Step-by-step explanation:

y(t) = 2 sin (4π t) + 5 cos (4π t)

We wish to convert this to:

y = A sin(ωt + φ)

We know that ω = 4π.  We also know the following:

5 = A sin φ

2 = A cos φ

Divide the first equation by the second equation:

5/2 = tan φ

φ = tan⁻¹(5/2)

Now, square the two equations and add them together.

5² + 2² = (A sin φ)² + (A cos φ)²

29 = A²

A = √29

The equation of the wave is therefore:

y = √29 sin(4π t + tan⁻¹(5/2))

The maximum negative position is -√29.  And half of that is -½√29.

-½√29 = √29 sin(4π t + tan⁻¹(5/2))

-½ = sin(4π t + tan⁻¹(5/2))

7π/6 + 2kπ or 11π/6 + 2kπ = 4π t + tan⁻¹(5/2)

7 + 12k or 11 + 12k = 24t + 6 tan⁻¹(5/2) / π

t = (7 + 12k − 6 tan⁻¹(5/2) / π) / 24 or (11 + 12k − 6 tan⁻¹(5/2) / π) / 24

Trying different integer values of k, we find there are two possible values for t between 0 and 0.5, both when k = 0.

t = (7 − 6 tan⁻¹(5/2) / π) / 24 or (11 − 6 tan⁻¹(5/2) / π) / 24

t ≈ 0.20 or 0.36

olganol [36]

The proportion can be used to find the distance on the map (x) that represents 50 miles will be x/50 = 5 / 200. Then the correct option is A.

<h3>What are ratio and proportion?</h3>

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

The scale on a map shows that 200 miles is represented by 5 inches on a map.

Then the proportion can be used to find the distance on the map (x) that represents 50 miles will be

x/50 = 5 / 200

Then  the correct option is A.

More about the ratio and the proportion link is given below.

Can I get some help with this question

Тhe third angle of the triangle = 90 - 60 = 30°

In a 30-60-90  triangle the side opposite the 30 degree angle is half the length of the hypotenuse, therefore y = \frac{8 \sqrt{3} }{2}=4 \sqrt{3}

x=8 \sqrt{3} \cdot \cos30^o =8 \sqrt{3} \cdot { \frac{ \sqrt{3} }{2} } =12

The answer is x = 12, y = 4√3
