Answer:

Step-by-step explanation:

The transformations you want are ...

90° CCW: (x, y) ⇒ (-y, x)
reflection over x-axis: (x, y) ⇒ (x, -y)
translation by your rule: (x, y) ⇒ (x+6, y-1)

Taken together, these make the transformation ...

(x, y) ⇒ (-y+6, -x-1)

So, your points become ...

A(0, 0) ⇒ A'(6, -1)

B(8, 1) ⇒ B'(5, -9)

C(5, 5) ⇒ C'(1, -6)

Three friends Kofi,Yaw and Musa are in partnership business in which Kofi and Yaw contributed 5/9 and 2/15 of the cost of 14000.

wlad13 [49]

Answer:

(a) $Total = 45000$

(b) Yaw, Musa and Kofi

Step-by-step explanation:

Given

$Kofi =5/9$

$Yaw = 2/15$

$Musa = 14000$

Solving (a): The cost of the business

First, we solve for the fraction of Musa

$Musa + Kofi + Yaw = 1$

$Musa = 1 - (Kofi + Yaw )$

$Musa = 1 - (5/9 + 2/15)$

$Musa = 1 - (\frac{25+6}{45})$

$Musa = 1 - \frac{31}{45}$

$Musa = \frac{45 - 31}{45}$

$Musa = \frac{14}{45}$

So, we have:

$\frac{14}{45} * Total = 14000$

Make Total the subject

$Total = 14000 * \frac{45}{14}$

$Total = 1000 * 45$

$Total = 45000$

Solving (b): Partners in ascending order

First, represent the fractions as decimals

$Kofi =5/9$ $= 0.5556$

$Yaw = 2/15$ $= 0.1333$

$Musa = \frac{14}{45}$ $= 0.3111$

From the conversion above, the least is 0.1333 (Yaw), then 0.3111 (Musa), then 0.5556 (Kofi).

<em>So, the order is: Yaw, Musa and Kofi</em>

In a survey, 600 adults in a certain country were asked how many hours they worked in the

Snowcat [4.5K]

Answer:

C. Correct

Step-by-step explanation:

The interpretation of a confidence interval of x% is that we are x% that this interval contains the mean of the population.

So, for example, the interpretation of a confidence interval of 95% is that we are 95% that this interval contains the mean of the population.

In this problem, we have that:

Based on the results, a 95% confidence interval for mean number of hours worked was lower bound: 41.5 and upper bound: 45.6.

Also, the following affiration:

(A) There is a 95% chance the mean number of hours worked by adults in this country in the previous week was between 41.5 hours and 45.6 hours.

This is correct

So, the answer is:

C. Correct
