Answer:
y = -4
Explanation:
The graph of y = 3 is horizontal.
The slope must be 0 for a line to be horizontal, and thus parallel to y=3.
In slope-intercept form (y = mx + b), “m” is the slope, “b” is the y-intercept.
When the slope, m = 0, the equation becomes y = b.
Point (4,-4) is written (x, y).
y = -4
Since y = b, b = -4.
Therefore, the equation is y = -4.
Answer:
a) Z for northern region = 1 , Z for southern region = -1.2
b) Southern region
Step-by-step explanation:
a) Z = (x – mean)/standard deviation
Le x be weight for birds
For the northern region
Z = (13 – 10)/3
Z = 1
For the southern region
Z = (13 – 16)/2.5
Z = -1.2
b) to find in what region is more likely to find a bird with 13 ounces, we calculate the probability for each z value
For the northern region
P (x>13) = P(z > 1)
Then we use the z table to find the area under the curve.
P (x>13) = 0.1587
For the southern region
P (x>13) = P(z > 1.2)
Then we use the z table to find the area under the curve.
P (x>13) = 0.8849
Is it more likely that a bird with a weight greater than 13 ounces lives in the southern region
Answer:
n = 3
Step-by-step explanation:
Let's consider the following proportion.
2/n = 2/3
To solve a proportion, we can use the rule that states that <em>the product of the end-terms is equal to the products of the inner-terms</em>. That is,
end-term × end-term = inner-term × inner-term
2 × 3 = 2 × n
6 = 2 × n
We can solve for n, dividing both terms by 2.
6/2 = 2 × n/2
n = 3
