22. The degree for each interior angle would be 125°.
An angle can be up to 180°(straight line) for a shape such as a polygon.
23. The answer would be a scalene triangle. Not all the angles are the same degree.
21 I'm not sure:(
ANSWER
0.9738 or 97.38%
EXPLANATION
Given:
Desired Outcome:
Probability that it will last 10 years
z-score for the sample:
p-value
For the z-score of 1.9376, the p-value is 0.9738 or 97.38%
Hence, the probability that it will last longer than 10 years if you randonly purchase one item is 97.38%
Answer:
right scalene
Step-by-step explanation:
Since all three sides have different lengths , this is a scalene triangle
(isosceles means two sides have the same lengths and equilateral means all three sides have the same length)
We have a right angle indicated by the box in the corner
Answer:
One way to write a polynomial is in standard form. In order to write any polynomial in standard form, you look at the degree of each term. You then write each term in order of degree, from highest to lowest, left to right.
Step-by-step explanation:
Ok we need a common coefficient of either x or y:
12x+21y=3
12x+40y=60
We can subtract one from the other to get:
19y=57
Now divide by 19 to get:
y=3
Now if we sub this back in we see that:
3x+30=15
3x=-15
x=-5
