One hundred teachers attended a seminar on mathematical problem solving. The attitudes of representative sample of 12 of the tea

GenaCL600 [577]

Answer:

Step-by-step explanation:

Mean = (3+7+-1+1+0+5+-3+2+-1+6+5+-2)/12

= 1.833

median is middle of ordered numbers -3/-2/-1/-1/0/1/2/3/5/5/6/8/7 here between the 6th and the 7th since with even number sample, there is not a unique middle. This would be 1.5

Standard deviation = √ 123.67/12

√10.3

=3.21

the change score that is 2.2 standard deviations below the mean.

1.83 - 2.2(3.21)

= 5.232

Find the kissing lengths of the sides of the triangle.

alina1380 [7]

Answer: The last option.

Step-by-step explanation:

The triangle shown in the figure attached is a right triangle.

1. You can calculate the lenght a as following:

$sin\alpha=\frac{opposite}{hypotenuse}$

$opposite=a\\hypotenuse=6in\\\alpha=30\°$

Substitute values and solve for a. Then, you obtain:

$sin(30\°)=\frac{a}{6in}\\a=6in*sin(30\°)\\a=3in$

2. You can calculate the lenght b as following:

$cos\alpha=\frac{adjacent}{hypotenuse}$

$adjacent=b\\hypotenuse=6in\\\alpha=30\°$

Substitute values and solve for b. Then, you obtain:

$cos(30\°)=\frac{b}{6in}\\b=6in*cos(30\°)$

$b=3\sqrt{3}in$
