Answer:

Step-by-step explanation:

the sum of the interior angles of a triangles is 180°

180 = 75 + 50 + x

x = 180 - 75 - 50

x = 55°

-----------------------

check

55 + 75 + 50 = 180°

the answer is good

Insect Weights Consider a dataset giving the adult weight of species of insects. Most species of insects weigh less than 5 grams

Ann [662]

Answer:

Step-by-step explanation:

71 grams would definitely be an outlier on the high side, whereas "most" species would weigh much less. Thus, the graph of this distribution of weights would be skewed towards the lower side, that is, to the left.

0.5x-7= 0.3 solve the equation<br><br><br><br><br>

Lena [83]

Answer:

<h3> $\boxed{ \bold{ \boxed{ \sf{x = 14.6}}}}$ </h3>

Step-by-step explanation:

$\sf{0.5x - 7 = 0.3}$

Move 7 to right hand side and change it's sign

⇒ $\sf{0.5x = 0.3 + 7}$

Add the numbers

⇒ $\sf{0.5x = 7.3}$

Divide both sides of the equation by 0.5

⇒ $\sf{ \frac{0.5x}{0.5} = \frac{7.3}{0.5} }$

Calculate

⇒ $\sf{x = 14.6}$

Hope I helped!

Can anybody tell me what’s going on here?

masha68 [24]

Step-by-step explanation:

We are given a theta degree measure of sin in a specific interval. We are asked to find half of that degree measure.

The interval it ask us to find it in is between 2 pi and 5 pi over 2.

That is 360 degrees to 450 degrees. If you use reference angles, that is between the 0 degrees and 90 degrees. So that means our measure is going to be in the 1st quadrant.

Replace x with theta

$\sin( \frac{x}{2} ) = + - \sqrt{ \frac{1 - \cos(x) }{2} }$
