I. The value of x is equal to 8.
II. The dimensions of the rectangle are 13 and 5 inches respectively.
<u>Given the following data:</u>
- Area of a rectangle = 65 square inches.
- Length of rectangle = x + 5 inches
- Width of rectangle = x - 3 inches
To find the value of x, and the dimensions of the rectangle:
Mathematically, the area of a rectangle is given by the formula:
Substituting the values, we have:
x = 8 or x = -10
<u>For the</u><u> length:</u>
when x = 8
Length = 13 inches.
<u>For the</u><u> width:</u>
when x = 8
Length = 5 inches.

Answer:
There are 118 plants that weight between 13 and 16 pounds
Step-by-step explanation:
For any normal random variable X with mean μ and standard deviation σ : X ~ Normal(μ, σ)
This can be translated into standard normal units by :
Let X be the weight of the plant
X ~ Normal( 15 , 1.75 )
To find : P( 13 < X < 16 )
= P( -1.142857 < Z < 0.5714286 )
= P( Z < 0.5714286 ) - P( Z < -1.142857 )
= 0.7161454 - 0.1265490
= 0.5895965
So, the probability that any one of the plants weights between 13 and 16 pounds is 0.5895965
Hence, The expected number of plants out of 200 that will weight between 13 and 16 = 0.5895965 × 200
= 117.9193
Therefore, There are 118 plants that weight between 13 and 16 pounds.
0.52 Im pretty sure. Hope this helps!
Answer:
x = -5, y= 7. You can check this yourself by plugging in the numbers.
