Answer:
2625 bacteria
Step-by-step explanation:
y= 250*(3*14)/4
y= 250*42/4
y= 10500/4
y= 2625
Answer:
The study is an observational study because the study examines individuals in the sample, but does not try to influence the response variable.
Step-by-step explanation:
The shape in the middle is a quadrilateral, so the bottom right hand corner should add up to the rest of the angles to give 360 degrees.
40 + 80 + 110 = 230°
360 - 230 = 130°
The line on which x is on is a straight line, and a straight line is 180 degrees.
Therefore x has to be 180 - 130 to make sure it adds up to give 180 degrees.
180 - 130 = 50
∴ x = 50°
Answer:
x = 20 degrees
Explanation:
With a 20 degree angle on the direct opposite side, it shows that x is also 20 degrees; and the other two angles would be 160 degrees.
Hope this helps :)
