The weights of 1,000 men in a certain town follow a normal distribution with a mean of 150 pounds and a standard deviation of 15 pounds. From the data, we can conclude that the number of men weighing more than 165 pounds is beyond the mean weight of 1000 men and the number of men weighing less than 135 pounds is less than the mean weight of 1000 men.
3x + 2y = 4
A) (-2, 5)
B) (1, 4)
C) (2, -1)
D) (4, -4)
Answer:
(C) (2,-1)
Step-by-step explanation:
The given system of equations is :
(1)
and (2)
Multiply equation (1) with 2 and then subtract equation (2) from it, we get
⇒
⇒
⇒
Substitute the value of x=2 in equation (1), we get
⇒
⇒
⇒
Therefore, x=2 and y=-1. that is (2,-1).
9 × 10-4
90 × 10-4
9 × 10-6
34 + |18 = -9| × -5.
Answer:
-11
Step-by-step explanation:
Calculate the absolute value of -9, which is 9.
Multiply 9 by -5, which equals -45.
Finally, add 34 to -45:
34 + (-45) = -11
So, the simplified expression is -11.
