A study9 compared personality characteristics between adult children of alcoholics and a control group matched on age and gender
34kurt

Answer:

df.= 28

P - value = 0.0124 < 0.05

There is a difference between the mean of  the well-being measure for the children of alcoholics, and a mean of the control group.

Step-by-step explanation:

As the given test is dependent or paired test the degrees of freedom is n-1 = 20-1 = 28

The reported t = 2.67

The P value for ∝= 0.05 at  calculated t= 2.67 and 28 d.f is 0.0124 which is less than 0.05 .

The null hypothesis is rejected.

The null hypothesis is that there is no difference between the means of the two samples.

H0: u1 = u2

The alternate hypotheis is accepted that there is  difference between the means of the two samples.

Ha: u1≠ u2

There is a difference between the mean of  the well-being measure for the children of alcoholics, and a mean of the control group.

A circular gift has a 4.75 inch radius. alyssa wants to wrap a ribbon that costs $0.50 per inch around the gift. How much money
Montano1993 [528]

The Alyssa will spend $14.915 for wrap a ribbon around the gift, if a ribbon costs $0.50 per inch.

Step-by-step explanation:

The given is,

                      A circular gift has a 4.75 inch radius

                      Ribbon that costs $0.50 per inch

Step:1

           Formula to calculate the perimeter of circle,

                               Perimeter, P = 2\pi r......................(1)

           Where, r - Radius of circle

           From the given,

                                                  r = 4.75 inches

          Equation (1) becomes,

                                                P = 2 (\pi )(4.75)

                                                    = 2(3.14)(4.75)            (∵ \pi= 3.14)

                                                    =2(14.915)

                                                    =29.83

                              Perimeter, P = 29.83 inches

Step:2

            Cost for wrap the ribbon to around the circular gift,

                                          = Perimeter of circular gift × ribbon cost per inch

                                          = (29.83 × 0.50)

                                          = $14.915

          Cost for wrap the ribbon to around the circular gift = $14.915      

Result:

           The Alyssa will spend $14.915 for wrap a ribbon around the gift, if a ribbon costs $0.50 per inch.

????!! Someone please explain this
oee [108]

Answer:

$24

Step-by-step explanation:

First, find the cost to cover one pair of shoes.

Cost to cover one pair of shoes = surface area of the shoe box × cost per square inch

= 2(LW + LH + HW) × 0.02

L = 14 in.

W = 8 in.

H = 4 in.

Plug in the values

Cost to cover one pair of shoes = 2(14*8 + 14*4 + 4*8) × 0.02

= 2(112 + 56 + 32) × 0.02

= 2(200) × 0.02

= 400 × 0.02 = 8

Cost to cover one pair of shoes = $8

Cost to cover 3 pairs of shoes = 3*8 = $24
