Answer:
3d - 4 = -0.4
When d = 1.2
Step-by-step explanation:
Use PEMDAS to solve the equation
3(1.2) - 4
= 3.6 - 4
= -0.4
Answer:
2(2x+1)
Step-by-step explanation:
4x and 2 are both divisible by 2.
The coordinate is an ordered pair

. We have a number, 5, for y, which we can substitute (plug-in) for y in the equation of the line and solve for x.

The u-x and o-x from the given parameters of the population and the sample size will be u =28 and standard deviation is 5.
<h3>How to calculate the values?</h3>
From the information given about the population and sample mean, the values include:
u=27 o=5 n=14
The standard deviation will be:
= 5/✓14
= 5/3.74
= 1.34
Therefore, u-x and o-x from the given parameters of the population and the sample size will be u =28 and standard deviation is 1.34.
