The safety inspector notes that Ray also needs to plan for a vertical ladder through the center of the coaster's parabolic shape
Pie

Answer:

  • vertex: (-5/8, 7/16)
  • axis of symmetry: x = -5/8

Step-by-step explanation:

For quadratic ax²+bx+c, the axis of symmetry is located at x=-b/(2a).

Here, we have a=4, b=5, so the axis of symmetry is ...

... x = -5/(2·4) = -5/8

_____

The vertex y-value will be f(-5/8).

... f(-5/8) = (4·(-5/8) +5)·(-5/8) +2 = (5/2)·(-5/8) +2 = -25/16 +32/16

... f(-5/8) = 7/16

_____

The axis of symmetry is x = -5/8; the vertex is (-5/8, 7/16).

The width of a rectangle is 7 meters greater than its length. If the area of the rectangle is 170 square meters, write the quadr
soldier1979 [14.2K]
Since x is the length, then x+7 has to be the width.
The area of a rectangle can be found via the formula :
A = length * width
So if we replace the area with the given number (170) and the length, and width, with what we assumed, we get..
170 = x * (x+7)
[which is.. ]
170 = x^2 +7x
0 = x^2 +7x - 170

And that is the answer.

A marketing research company desires to know the mean consumption of milk per week among males over age 32. A sample of 710 male
nydimaria [60]

Answer:

(4.5, 4.7)

Step-by-step explanation:

Hi!

Lets call X to the consumption of milk per week among males over age 32. X has a normal distribution with mean μ and standard deviation σ.

X \sim N(\mu, \sigma)

When you know the population standard deviation σ of X  ,  and the sample mean is \hat X, the  variable q has distribution N(0,1):

q = \frac{\hat X - \mu}{\sigma} \sim N(0,1)

Then you have:

P(-k < q

This defines a C - level confidence interval. For each C the value of k is well known. In this case C = 0.98, then k = 2.326

Then the confidence interval is:

(4.6 - 2.326*\frac{0.8}{\sqrt{710}}, 4.6 + 2.326*\frac{0.8}{\sqrt{710}})\\ (4.5, 4.7)
