The table below shows the distance y, in miles per minute, of a toy car at different times x, in minutes: Time (x) (minutes) 10

20 30 40 Distance (y) (miles) 0.2 0.8 0.1 0.4 Part A: What is the most likely value of the correlation coefficient of the data in the table? Based on the correlation coefficient, describe the relationship between time and distance of the toy car. (4 points) [Choose the value of correlation coefficient from −1, 1, −0.04, 0.99] Part B: What is the value of the slope of the graph of distance versus time between 10 minutes and 20 minutes, and what does the slope represent? (3 points) Part C: Does the data in the table represent correlation or causation? Explain your answer. (3 points)

How many terms does the polynomial have? 2p2q−3pq 1 2 3 4
Pachacha [2.7K]

Answer:

Polynomials are classified according to their number of terms. 4x3 +3y + 3x2 has three terms, -12zy has 1 term, and 15 - x2 has two terms. As already mentioned, a polynomial with 1 term is a monomial. A polynomial with two terms is a binomial, and a polynomial with three terms is a trinomial.

Which ratio forms a proportion with 18/27
JulsSmile [24]

Answer:

\frac{2}{3}

Step-by-step explanation:

The given ratio is \frac{18}{27}

9 is the common factor of 18 and 27

divide numerator and denominator by 9

\frac{18/9}{27/9} =\frac{2}{3}

hence \frac{2}{3} is proportion with \frac{18}{27}

So I have another trigonometry question PLZ HELP ME I'm clueless at this rate I have like a little idea but I'm lost, SO PLZZZ!
Sergio039 [100]

Answer:

1) The windsurfer is approximately 580 ft from each lifeguard stand.

2) The distance between the Earth and Mercury is approximately 61 million miles.

Step-by-step explanation:

The image other two situations described is presented in the attached image to this answer.

1) From the attached image, the windsurfer forms a right angled triangle with each of the lifeguard stand and the midpoint between the two lifeguard stands.

Hence, the angle at the top of the triangle is half of 30°, 15° and the distance from the midpoint of the lifeguard stands to the lifeguard stands is 300/2 = 150 ft.

Let the required distance of the windsurfer from each of the lifeguard stands be x.

Using trigonometric relations,

Sin 15° = (150/x)

x = 150 ÷ sin 15° = 150 ÷ 0.2588

x = 579.6 ft = 580 ft to the nearest whole number

2) From the image, the Sun, Earth and Mercury form a triangle.

Let the possible distance between the Earth and Mercury be y.

Using cosine rule,

y² = 36² + 93² - (2×36×93×cos 22°)

y² = 3,736.5769098208

y = √3,736.5769098208 = 61.13 million miles = 61 million miles to the nearest million miles.

Hope this Helps!!!

it's asking me to find an equation for the line I drew but I don't know how, and I'm not even sure if my line is correct.
vovangra [49]
Your line is wrong from the start. But for the equation:
y =  \frac{15}{2} x

Darin can purchase tile at a store for 0.79 per tile and rent a tile saw for $24. At another store, he can borrow the tile saw f
ankoles [38]
Let us denote the number of tiles by T.

In the first store, if Darin bought T tiles, he would need to spend:
                        0.79\times T+24 (measured in $)

In the second store, if Darin bought T tiles, he would need to spend:
                        1.19\times T (measured in $)

For the cost to be the same at both stores, it means (measured in $)
                                           1.19T=0.79T+24

Moving 0.79T over to the left hand side and changing signs:
                                            1.19T-0.79T=24
                                            0.4T=24
                                            T= \frac{24}{0.4}
                                            T=60 tiles

Let's check. If he buys 60 tiles in the first store, he spends:
                              $0.79×60 + $24 = $47.40 + $24 = $71.40

If he buys 60 tiles in the second store, he spends:
                                               $1.19×60 = $71.40

∴ Darin needs to buy 60 tiles for the cost to be the same at both stores.
