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.

If f(n) = -6n + 2, find f (5/6)

joja [24]

$f( \frac{5}{6} ) = - 6( \frac{5}{6} ) + 2 \\ f( \frac{5}{6} ) = - \frac{30}{6} + 2 \\ f( \frac{5}{6} ) = - 5 + 2 \\ f( \frac{5}{6} ) = - 3$

antiseptic1488 [7]

Answer:

Find the graph that has (2,0)

Step-by-step explanation:

$\frac{1}{2}x -1=-x+2$

+ x +x

$\frac{3}{2}x - 1 = 2$

$2(\frac{3}{2}x - 1 = 2)$

3x - 2 = 4

+ 2 + 2

3x = 6

/3 /3

x = 2

Your image is blurry, but the point that has (2,0)
