Novay_Z [31]3 years ago
4 0

Answer:

No

Step-by-step explanation:

If you plug in the points, you will get 0 = -2.

0 is not equal to -2, so those points do not make the equation true.

In a genetic experiment involving flower color in phlox, a ratio of 3 blue-flowered plants to 1 whiteflowered plant was expected
aliya0001 [1]

Answer: The observed ratio is different from the expected ratio.

Step-by-step explanation:

Since we have given that

Expected ratio :

Ratio of blue flowered plants to white flowered plant = 3:1

Observed results:

Number of blue flowered plants = 35

Number of white flowered plants = 14

So, Ratio of blue flowered plants : white flowered plants

35:14\\\\=5:2

So, 5:2 ≠ 3:1

Hence, the observed ratio is different from the expected ratio.

Answer:

The answer is 0.71 per ounce.

Step-by-step explanation:

You can use proportions to solve this.

\frac{89.95 dollars}{64lb} = \frac{1 dollar}{x} \\64 * 1 = 64\\89.95 * x = 89.95x\\\\\frac{64}{89.95} = \frac{89.95x}{89.95}\\\\0.7115063924 = x\\Which when rounded to the nearest hundredths is:\\0.71

Equation y = x - 7

<u>Step 2: Find</u>

  1. Substitute in point [Equation]:                                                                         0 = 7 - 7
  2. Subtract:                                                                                                            0 = 0

Since 0 = 0 is true, then it would be a solution to the equation.
