Answer:
1
Step-by-step explanation:
The zeroes or x intercepts are when the line crosses through the x-axis.
In this case you should only have one being (1) because the line only passes the x-axis once. Also by real zeroes it means non -5i #s so nothing with an (i) for imaginary #'s.
Hope this helps.
Step-by-step explanation:
May you reword it? I don't quite understand.
Answer:
find the square of both numbers
13²=169
5²=25
minus the square
169-25 to get 144
find the square root of 144
✓144=12 the third side is 12
Answer:
the probability is 0.0750
Step-by-step explanation:
The computation of the probability is shown below;
The mean of x is
= 1.5 ÷ √79
= 0.1688
Now the probability is
= P(Z < -0.3 ÷ 0.1688) + P(\bar{x} > 0.3 ÷ 0.1688)
= P(Z < -1.78) + P(Z > 1.78)
= P(Z < -1.78) + 1 - P(Z < 1.78
= 0.0375 + 1 - 0.9625
= 0.0750
hence, the probability is 0.0750
