Answer:
Hello,
Step-by-step explanation:
Answer: 0.0766
Step-by-step explanation:
Let x be the random team scores.
Given: Mean = 76
Standard deviation = 8.4
We assume that x follows normal distribution.
The probability that a random team scores less than 64 points = P(x<60)
Hence, the probability that a random team scores less than 64 points =0.0766
Answer:
a) (1, 2) not on the graph.
b) (1, -1) is on the graph.
Step-by-step explanation:
Given the equation of the line as:
The points given are
a) (1, 2)
To determine whether it is on the graph of the line or not.
To do so, we can do 2 things:
1. Draw the graph and plot the point on the graph to check whether it is on the graph or not.
2. To put the point in the given equation of the line, whether the equation is satisfied or not.
For method 1: Kindly refer to the attached image of the line and point plotted.
Method 2:
Let us put in the Left Hand Side (LHS) of equation.
(1, 2) Not on the graph.
(b) (1, -1)
For method 1: Kindly refer to the attached image of the line and point plotted.
Method 2:
Let us put in the Left Hand Side (LHS) of equation.
(1, -1) is on the graph.
Answer:
Write it like x>3 instead.
Work:
Solve for x by simplifying both sides of the inequality, then isolating the variable.
1.8 = 1.80
If there is a 0 after any number in a decimal it has no value,
for example, 1.2323000 = 1.2323
