Steve and Elizabeth decide to become partners in a children’s cooking school. They need $80,000 for the franchise. They invest i

PilotLPTM [1.2K]

Answer:

The share of Steve is $34,285 .71

The share of Elizabeth is $45,714.28

Step-by-step explanation:

The total investment of Steve and Elizabeth in cooking school = $80, 000

The ratio of investment of Steve and Elizabeth = 3: 4

Let us assume the common factor in the ratio is m.

So, the ratio of Steve = 3 m

and the ratio of Steve = 4 m

So, according to the question:

⇒ 3 m + 4 m = 80,000

or, 7 m = 80,000

⇒ m = 80,000 / 7 = 11,428.57

or, m = 11,428.57

⇒ The share of Steve = 3 m = 3 x (11,428.57) = 34,285 .71

⇒ The share of Elizabeth = 4 m = 4 x (11,428.57) = 45,714.28

The area of a rectangular wall of a barn is 45 square feet. Its length is 12 feet longer than the width. Find the length and wid

ValentinkaMS [17]

Answer:

Mark as brainliest

Step-by-step explanation:

by using the formula for area: A= L x W substitute in what you know: A = 54 , the length in terms of the width so use

L=12 + 2W.

Now when everything is plugged in you now have: 54 = (12 + 2W) x W

Then use the Distributive Property to simplify: 54 = 12W + 2W2

Since you know have a quadratic to solve get it in the form ax2+bx + c = 0 so that you can solve it:

You do this by subtracting 54 from both sides and putting the 2W2 first so now it looks like this:

2W2 + 12W -54 = 0

Using the quadratic formula where a =2, b = 12, and c = -54.

Find b2-4ac which is the discriminant:

(12)2-4*2*(-54)=576

Take the square root of 576= 24

Now substitute the rest of the values into the Quadratic Formula:

It will look something like this: W = (-b plus or minus the square root of the discriminant)/2a

The two possible answers are:

W = (-12 + 24)/4 and W = (-12 - 24)/4

W = 12/4= 3 and W = -36/4= -9 (This second answer isn't possible because length can't be negative)

So the answer is:

Width = 3 feet Length = 12 + 2W = 12 + 2*3= 12 + 6 = 18 feet

This checks because A = L x W and 54 = 18 x 3

Find the critical value from the Studentized range distribution for H0: μ1 = μ2 = μ3 = μ4 = μ5, with n = 35 at α = 0.01. Provide

Aleonysh [2.5K]

Answer:

t-value = 2.441

Step-by-step explanation:

Let's assume that this is a one-tailed test to calculate the critical value, the process is this:

Calculate alpha (α): α = 1 - (confidence level / 100) , but we already have this α=0.01
Find the critical probability (p*): p* = 1 - α/2 = 1-0.005=0.995
Then, the critical value would be shown as a t statistic, but for this we need:

degrees of freedom (df)= n-1=35-1=34

The critical t statistic (t*) or critical value is the t-value having degrees of freedom equal to 34 and a cumulative probability equal to 0.995.

From the attached table we can see:

t-value = 2.441
