3. A research study asked children which of four different emotions they associated with the color red. The response and gender

user100 [1]

Answer:

This is required solution

Step-by-step explanation:

Given that:

for male

joy = 28

happiness = 20

love = 40

anger = 18

a] we need to calculate the percentage of emotions for the male

using formula for percentage

$\percentage\ of\ emotions=\dfrac{emotion}{total\ emotions}\times100$

percentage of joy = $\dfrac{28}{106}\times100$

percentage of joy = 26.41

percentage of happiness = $\dfrac{20}{106}\times100$

percentage of happiness = 18.86

percentage of love = $\dfrac{40}{106}\times100$

percentage of love = 37.73

percentage of anger = $\dfrac{18}{106}\times100$

percentage of anger = 16.98

for female

joy = 61

happiness = 25

love = 80

anger = 60

we need to calculate the percentage of emotions for the female

using formula for percentage

$\percentage\ of\ emotions=\dfrac{emotion}{total\ emotions}\times100$

percentage of joy = $\dfrac{61}{226}\times100$

percentage of joy = 26.99

percentage of happiness = $\dfrac{25}{226}\times100$

percentage of happiness = 11.06

percentage of love = $\dfrac{80}{226}\times100$

percentage of love = 35.39

percentage of anger = $\dfrac{60}{226}\times100$

percentage of anger = 26.54

B] We need to draw a bar graph for male and female

using percentage of emotion of male and female

according to using percentage we draw a bar graph using data of part A.

Hence, this is required solution

Use the formula for the area of a circle to find the area of the bull’s eye and the next ring together A. 22,686.5 mm2

nirvana33 [79]

Answer:

Step-by-step explanation:

We know that the bull's eye target has a diameter of 20 centimeters, which equals 200 milimeters.

So, we find the area

$A_{target}= \pi (100mm) ^{2} =(3.14)(10000) mm^{2} =31,400 mm^{2}$

Therefore, the right answer is B.

If two sides of a triangle measure 4 cm and 6 cm what could be the measure of the third side? A. 9 B. 10 C. 11 D. 12

lesya692 [45]

Answer:

A. 9

Step-by-step explanation:

Triangle Inequality: the lengths of any two sides of a triangle add up to more than the third side.

B. 10 can't be the answer because the 4 cm and 6 cm sides would just meet at a point on the 10 cm sides.

C. 11 and D. 12 can't be answers because the 4 cm and 6 cm sides would not meet (kind of like windshield wipers that are too short).

It's impossible to give exact answer as you've not attached the image. But I think I can help you by giving some rulles about rotation. 180° rotation is (x;y) change to (-x;-y); 90° counterclockwise (x,y) change to (-y, x); then clockwise <span>90° (x,y), cange to (y, -x). Hope it will help.
