Answer:

y = 4x - 1

Step-by-step explanation:

Assuming you require the equation of the line.

The equation of a line in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

Here m = 4 and c = - 1, thus

y = 4x - 1 ← equation of line

I do roadwork site 20 cones are placed on 50 feet of road. at this rate, how many cones are placed along 35 feet of road?

satela [25.4K]

You would cross multiply for this.
$\frac{20}{50} = \frac{x}{35}$

20 · 35 = 700
Then you would divide.
700 ÷ 50 = 14

There would be 14 cones placed along 35 feet of road.

A sample of 75 information systems managers had an average hourly income of $40.75 with a standard deviation of $7.00. The 95% c

lorasvet [3.4K]

Answer:

The 95% confidence interval for the average hourly wage of all information system managers is (39.14,42.36)

Step-by-step explanation:

In order to calculate the 95% confidence interval for the average hourly wage we would have to calculate first the margin of error as follows:

ME=t0.05/2,n-1s/√n

for n=75, t0.025,74=1.993

Therefore, ME=1.993*7/√75

ME=1.61

Therefore, the 95% confidence interval for the average hourly income of all syatem manager would be as follows:

(X-ME,X+ME)=(40.75-1.61,40.75+1.61)

=(39.14,42.36)

Schach [20]

Let's use a rule of three:

Therefore,

$\begin{gathered} x=\frac{544\cdot44}{3} \\ \Rightarrow x=7978.67 \end{gathered}$

We would neeed 7978.67 lb of blue grass seed.
