<span>Simplifying y = 3x + -9 + 8x Reorder the terms: y = -9 + 3x + 8x Combine like terms: 3x + 8x = 11x y = -9 + 11x Solving y = -9 + 11x Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Simplifying y = -9 + 11x</span>

A monk crossbred plants which can have purple or white flowers and obtained 511 plants with white flowers and 337 plants with pu
Zepler [3.9K]

Answer:

For purple;

P(p) = 337/848 = 0.40

For white;

P(w) = 511/848 = 0.60

Step-by-step explanation:

Given;

Number of plants with purple flowers P = 337

Number of plants with white flowers W = 511

Total T = 337 + 511 = 848

For purple;

the empirical Probability that a plant had purple flowers P(p) is

P(p) = Number of plants with purple flowers/total number of plants

P(p) = P/T

Substituting the values, we have;

P(p) = 337/848 = 0.40

For white;

the empirical Probability that a plant had white flowers P(w) is

P(w) = Number of plants with white flowers/total number of plants

P(w) = W/T

Substituting the values, we have;

P(w) = 511/848 = 0.60

10) Which has the lowest price per ounce?<br><br>please refer to the chart above &lt;3​
melisa1 [442]

Answer:

The lowest price per once is: "Don's store" $ 0.101

Step-by-step explanation:

You have to apply a 3 way rule

so:

1) 60 oz ----- $6.50

1 oz    ----- =(1 oz X $6.50)/ 60

                = $0.108

2) 54 oz ----- $5.50

    1 oz    ----- =(1 oz X $5.50)/ 54

                = $0.101

3) 48 oz ----- $5.61

      1 oz    ----- =(1 oz X $5.61)/ 48

                = $0.116

4) 40 oz ----- $4.50

      1 oz    ----- =(1 oz X $4.50)/ 40

                = $0.112

1. Two cross roads, each of width 10 m, cut at right angles through the centre of a rectangular park of length 750
just olya [345]

Answer:

Length of the road parallel to the length of the park= 700m

Width of the road= 10m

Area of the road= l\times b=700m\times10m=7000m^2l×b=700m×10m=7000m

2

Length of the road parallel to the breadth of the park =300m

Width of the road= 10m

Area of this road= l\times b=300m\times10=3000m^2l×b=300m×10=3000m

2

Area of both the roads

=7000m^2+3000m^2-Area\ of\ the\ common\ portion\=7000m

2

+3000m

2

−Area of the common portion

=10000m^2-10m\times10m=10000m

2

−10m×10m

=10000m^2-100m^2=10000m

2

−100m

2

=9900m^2=0.99=9900m

2

=0.99

Area of the park = l\times bl×b

=700m\times300m=210000m^2=700m×300m=210000m

2

Area of the park excluding the roads

=210000m^2-9900m^2=210000m

2

−9900m

2

=200100m^2=20.01=200100m

2

=20.01
