To solve for x in terms of b, simply treat b as a number, and solve for x as usual: first of all, we expand the left hand side:
Subtract 10 from both sides:
Divide both sides by -2b:
This means that in particular, if we set 
, we have
Bar graph because a stem and leaf plot is used when there are big numbers and also when there is a lot of numbers. It CANNOT be used for comparing different data.
Bar graphs are used to compare data. To be more specific, you should use a double bar graph because:
Double bar graphs have 2 or more bars for compariong
Bar graphs are usually used to show length
Answer: Double bar graph (bar graph)
Hope this helps :)
Answer:
True
Step-by-step explanation:
Point estimation of a population parameter provides an estimate of a single value calculated from the sample that is likely to be close to its value to the unknown parameter. Itis to be noted that a point estimate will not in general be equal to the population parameter as the random sample used is one of the many possible samples which could be chosen from the population.
For example, in estimation, we may estimate the mean and the variance of a population by computing the mean and the variance of the sample drawn from a population.
Answer:
C words
Step-by-step explanation:
Answer:
a. (5x+75)°
b. x = 21
c. X° = 21° and (4x+75)°= 159°
Step-by-step explanation:
A. Combine like integers.
B. (5x+75)°=180° Because they are suplementary angles.
5x°= 105°
5x ÷5 = 105 ÷ 5
x = 21
C. (4x + 75)°
4(21) + 75
84 + 75 = 159°
