F(x)=5x-3 find the domain and range
lakkis [162]

Answer:

Let's solve for f.

fx=5x−3

Step 1: Divide both sides by x.

fx

x

=

5x−3

x

f=

5x−3

x

Let's solve for x.

fx=5x−3

Step 1: Add -5x to both sides.

fx+−5x=5x−3+−5x

fx−5x=−3

Step 2: Factor out variable x.

x(f−5)=−3

Step 3: Divide both sides by f-5.

x(f−5)

f−5

=

−3

f−5

x=

−3

f−5

Answer:

x=

−3

f−5

Step-by-step explanation:

Hope I helped

In the context of a correlational study, what does the positive or negative sign of a correlation coefficient indicate?
Artyom0805 [142]

Answer:

Direct or inverse relation between two variables

Step-by-step explanation:

Now, we first have to understand that what is correlation study. In a correlational study, we try to find the relation between two variables. For example, mass and weight of a substance. If mass increases the weight will increase as well. it represent that both have strong positive correlation. Now the positive sign indicates that the correlation is directly proportional. Means if one variable increases, other will follow. Whereas, negative sign shows that two variables are inversely proportional, means, if one increases, other will decrease. For example any demand and supply system in economics. When supply is short, demand will rise, but if there is enough supply, demand will fall down accordingly.

Also notify that the coefficient is actually indicates the strength of relation between two variables. For example, if you pour water in container it will increase the weight of container, so it is directly proportional, now if you start to add honey, it will increase the weight of container more rapidly because honey has more density. So, coefficient of correlation for quantity of honey and weight of container is stronger than for quantity of water and weight of container.

Micheal's mean score for five tests was 82. if four of those tests were 83,75,93, and 67, what was the fifth score on his test?
bezimeni [28]

Let T represent the fifth test score. The average is the sum of scores divided by their number.

... 82 = (83 +75 +93 +67 +T)/5

... 410 = 318 +T . . . . . . . multiply by 5

... 92 = T . . . . . . . . . . . . subtract 318

The fifth score was 92.

_____

One of the ways I like to work problems like these is to add the differences from the mean. Those are ...

1, -7, 11, -15

so their sum is -10.

The final score must be 10 above the mean in order for this total to be zero. 10 above the mean is 92.
