Answer:
12/(7-4) + 5 * 3 = 19
Step-by-step explanation:
Given
Untrue Expression: 12 ( 7 − 4 ) + 5 3 = 19
Signs: +−×÷
Required
Use the given signs to make the equation true.
To solve this, the trial and error method will be adopted.
The trial and error method involves trying series of sign combinations in the given expression; whichever works is the right answer.
So, after few attempts the following makes the equation true
12/(7-4) + 5 * 3 = 19
To check if it's true or not; we simply expand the expression on the left hand side. This gives
12/3 + 5 * 3 = 19
4 + 5 * 3 = 19
4 + 15 = 19
19 = 19.
Hence, the sign combinations used in 12/(7-4) + 5 * 3 = 19 is correct.
Answer:
a. Problem A > Problem B
Step-by-step explanation:
Problem A:
f(x) = x3 + 5
f(-2) = (-2)3 + 5
f(-2) = (-6) + 5
f(-2) = -1
Problem B:
f(x) = x2 - 2
f(-2) = (-2)2 - 2
f(-2) = (-4) - 2
f(-2) = -6
Answer:
18.86
Step-by-step explanation:
8.2 x 4.6 = 37.72
37.72/2 = 18.86
Answer:
a. The data is skewed left
Step-by-step explanation:
Looking at the graph, the bars are noticeably much taller on the right side when compared to the left.
The mean is likely less than the median, if calculated.
The skewed side of the graph is opposite to what it looks like.
