Consider an event to be unlikely if its probability is less than or equal to 0.05.
204+287+376+137+130=1134
130/1134= .115
No, because the probability of a respondent with four or more cell phones in use is greater than 0.05.
Answer:
skewed to the left
Step-by-step explanation:
A histogram is used to represent data graphically. the histogram is made up of rectangles whose area is equal to the frequency of the data and whose width is equal to the class interval. the frequency is usually on the vertical axis while the class interval is usually on the horizontal axis.
If the mean is greater than the median, the histogram would be skewed to the right
If the mean is less than the median, the histogram would be skewed to the left.
The mean in this question is $46,200 while the median is $54,500. So, the histogram would be skewed to the left
Complementary angles are two angles whose measures add to a sum of 90 degrees. This can be expressed as the following formula:
A1 + A2 = 90
Substitute any known values into the equation above:
(2x + 1) + (x – 7) = 90
2x + 1 + x – 7 = 90
Combine like terms:
3x – 6 = 90
Add 6 to both sides of the equation:
3x = 96
Divide 3 from both sides of the equation:
x = 32
When (2x + 1) and (x – 7) are complementary, “x” is equal to 32.
I hope this helps!
100% - 25% = 75%
52.50 = 75% of what number?
52.50 = 0.75x
Let x = original cost
52.50 ÷ 0.75 = x
70 = x
The original cost was £70.
B. sometimes
sometimes it’s a line and sometimes it’s dashed depending on the less than great than sign
