Answer: Earth’s Best $1.67 Kroger $2

Step-by-step explanation:

$0.80 multiplied by 3 is $2.40 and $1.33 multiplied by 2 is $2.66.

$1.25 multiplied by 3 is $3.75 and $0.75 multiplied by 2 would be $1.50.

$0.80 multiplied by 3 is $2.40 and $0.75 multiplied by 2 is $1.50.

$1.67 multiplied by 3 is $5.01, but if you round it to the nearest cent, it’s $5 and $2 multiplied by 2 is $4, of course.

Hope this helps!

Plz help which one is not a chord
kaheart [24]

Answer:

Line FN.

Step-by-step explanation:

A chord is a line whose endpoints both lie on the circle.

All the other lines' endpoints are on the circle.

In line FN, point N is on the circle but point F is not.

This makes line FN not a chord.

The CEO of a large corporation asks his Human Resource (HR) director to study absenteeism among its executive-level managers at
Fynjy0 [20]

Answer:

Following are the answer to this question:

Step-by-step explanation:

Given:

n = 30 is the sample size.  

The mean  \bar X = 7.3 days.  

The standard deviation = 6.2 days.  

df = n-1  

     = 30-1 \\      =29

The importance level is \alpha = 0.10  

The table value is calculated with a function excel 2010:

= tinv (\ probility, \ freedom \ level) \\= tinv (0.10,29) \\ =1.699127\\ =  t_{al(2x-1)}= 1.699127

The method for calculating the trust interval of 90 percent for the true population means is:

Formula:

\bar X - t_{al 2,x-1} \frac{S}{\sqrt{n}} \leq \mu \leq \bar X+ t_{al 2,x-1}   \frac{S}{\sqrt{n}}

=\bar X - t_{0.5, 29} \frac{6.2}{\sqrt{30}} \leq \mu \leq \bar X+ t_{0.5, 29}   \frac{6.2}{\sqrt{30}}\\\\=7.3 -1.699127 \frac{6.2}{\sqrt{30}}\leq \mu \leq7.3 +1.699127 \frac{6.2}{\sqrt{30}}\\\\=7.3 -1.699127 (1.13196)\leq \mu \leq7.3 +1.699127  (1.13196) \\\\=5.37 \leq \mu  \leq 9.22 \\

It can rest assured that the true people needs that middle managers are unavailable from 5,37 to 9,23 during the years.

Please help me finish these for summer school :)
ValentinkaMS [17]
13.45 will be the answer

since we are finding the hypotenuse, the formula is a^2 + b^2 = c^2

this will then be 10^2 + 9^2 = c^2

181=c^2

c=13.45 :)
