The two-way frequency table below shows data on mindset and attendance at practice for students in Mateus's study.

andrezito [222]

Answer:

Relative frequencies

Growth mind set fixed mind set Total

Attendance

every practice 0.7 0.3 1

missed at-least

one practice 0.1344 0.8656 1

Step-by-step explanation:

Growth mind set fixed mind set total

Attendance

every practice 28 12 40

missed at-least

one practice 9 58 67

Relative frequencies

Growth mind set fixed mind set Total

Attendance

every practice $\frac{28}{40} = 0.7$ $\frac{12}{40} = 0.3$ 1

missed at-least

one practice $\frac{9}{67} = 0.1344$ $\frac{58}{67} = 0.8656$ 1

Final answer:-

Relative frequencies

Growth mind set fixed mind set Total

Attendance

every practice 0.7 0.3 1

missed at-least

one practice 0.1344 0.8656 1

A company currently has an advertisement that covers a bill board that is 30 ft wide by 70 ft high. The company wants to reduce

Sedbober [7]

Given :

A company currently has an advertisement that covers a bill board that is 30 ft wide by 70 ft high. The company wants to reduce the same advertisement to fit on a new billboard that is 25 ft wide by 40 ft high.

To Find :

The dimensions of the largest advertisement that will fix on the billboard without cropping the advertisement.

Solution :

Area of original bill board :

$A_i=30\times 70 = 2100\ ft^2$

Area of new bill board :

$A_f=25\times 40 = 1000\ ft^2$

Since, new bill board can be completely fitted in original bill board as its length and breadth both are smaller than that.

So, the dimensions of the largest advertisement that will fix on the billboard without cropping the advertisement is equal to 1000 ft².

Hence, this is the required solution.

Which graph best represents the feasibility region for the system shown above? ( pics are in this)

zalisa [80]

Consider the system of inequalities

$\left\{ \begin{array}{l} y\ge 2 \\ x\le 6 \\ y\le 3x+2 \\ y\le -x+10. \end{array}\right.$

1. Plot all lines that are determined by equalities (see attached diagram)

$\left\{ \begin{array}{l} y=2 \text{ (red line)} \\ x= 6 \text{ (blue line)}\\ y=3x+2 \text{ (green line)} \\ y= -x+10 \text{ (orange line)}. \end{array}\right.$

2. Determine which bounded part of the plane you should select:

$y\ge 2$ means that you should take points with y-coordinates greater than or equal to 2 (top part of the coordinate plane that was formed by the red line);
$x\le 6$ means that you should take points with x-coordinates less than or equal to 6 (left part of the coordinate plane that was formed by the blue line);
for $y\le 3x+2$ you can check where the origin is placed. Since $0\le 3\cdot 0+2$ , the origin belongs to the needed part and you have to take the right part of the coordinate plane that was formed by green line.
for $y\le -x+10$ you can check where the origin is placed. Since $0\le -1\cdot 0+10$ , the origin belongs to the needed part and you have to take the bottom part of the coordinate plane that was formed by orange line.

3. According to the previous explanations, the shaded region is as in A diagram.

Answer: correct choice is A.
