Answer:
a. Degree 4; 2 terms
b. Degree 2; 3 terms
c. Degree 3; 1 term
Step-by-step explanation:
Here, all you need is a few definitions. The "degree" of a polynomial is just the highest exponent you see, and be careful with this, because sometimes the exponents won't be arranged from high to low. In this case, they are. In a polynomial, a "term" is basically anything that sits between a plus/minus operation (i.e in 5x + 4, 5x and 4 are both "terms").
a. What's the highest exponent you see? 4. So the degree is 4. You have 5x^4 and 8 separated by a minus sign, so that'll be 2 terms.
b. The highest exponent here is just 2, so it's a degree 2 polynomial. Two minus signs, so count 'em up: 3 terms.
c. Highest exponent is 3, and since 9m^3 sits on its own, you only have the one term.
Note that something like 3abc is one term. 3a/b is also one term. So is 4ab^2cd. If it's being multiplied or divided, they're together like a family. Addition or subtraction separates terms; multiplication and division don't.
Answer:
D. The graph has a positive rate of change
Step-by-step explanation:
The graph's slope, or rate of change, is positive, which means that D is your answer.
Answer: IQR = 16
Step-by-step explanation:
The given data is 25 th percentile is 64, 50th percentile is 74 and 75 th percentile is 80.
percentage : 25 50 75
score : 64 74 80
Median:- The median is obtained by first arranging the data in ascending or descending order and applying the following rule.
If the number of observations is odd, then the median is observation
term
If the number of observations is even, then the median is observation and observations.
given n=3, middle term is '74'
In this given data the median is (M) = 74
Interquartile range IQR = median of upper half-median of lower half
= 80-64
= 16
IQR = 16
All the angles must add to 180degrees in a triangle.
180 = 59 + 35 + x
180 = 94 + x
86 = x
Supplementary angles x and z add to 180
180 = x + z
180 = 86 + z
94 = z
Now the last triangle is with angles 11, z, and y
they must add to 180 so...
180 = 11 + z + y
180 = 11 + 94 + y
180 = 105 + y
75 = y
The answer is B.)

Just put 20 over 100 and simplify. The answer is 1/5.
