Answer:
15 goals out of 50 penalty kicks was scored by brock
Step-by-step explanation:
If Brock shoots 50 penalty kicks and the probability that he scores a penalty kick is 3/10, the number of goal brock is expected to make can be expressed as:
Number of goals scored = probability value * total penalty kicks taken
Number of goals scored = 
Number of goals scored = 
Answer:
x = 26
Step-by-step explanation:
The sum of the angles around point O = 360°, thus
x + 3x + 256 = 360 , that is
4x + 256 = 360 ( subtract 256 from both sides )
4x = 104 ( divide both sides by 4 )
x = 26
Answer:
The IQR is the best measurement of spread for games and movies.
Step-by-step explanation:
Because both seem to have outliers, we want to use IQR instead of standard deviation to determine the spread of data.
Answer:
It allows to to know y-intercept formula which is used to graph a line.
Step-by-step explanation:
Y-intercept formula:
y=mx+b
M: slope (keep in fraction if it is fraction, to help you graph)
B: y-interecept
Answer:
true
Step-by-step explanation:
If the standard deviation is increased and the sample size and confidence level stay the same, then the margin of error will also be increased
