Answer:
Step-by-step explanation:
If one can of paint covers 400 square feet then this should be easy. Since you need 3,000 square feet covered with paint (and one paint can cover 400 sq) then just divide 3,000 by 400.
This will show you how many times 400 can go into 3,000 which is the same as saying "how many cans of paint can i used to cover 3,000 square feet?"
If so, what is the likely direction of bias?
explain your reasoning carefully.
Answer:
In order for a sample to be considered biased, some members of the total population must have either a larger or lower chance of being included in the sample. In this case, your sample contained 17 reviews. It is biased because it was completely voluntary and customers who have a bad experience with a product or service generally tend to express more their dissatisfaction than satisfied customers show their satisfaction.
In marketing, there is a saying that unsatisfied clients talk bad about our product or service 4 times more than satisfied clients. I'm not sure if this saying is exact or not, but all marketing research point in the same direction.
This means that clients that did not get a good service or got no service at all, are more likely to post a review about the company than clients who got a good service. This is what makes the sample biased.

Explanation
Supplementary angles are angles that sum up to give 180 degrees.
And for all rectangles, whether a square one or non-square one, all of the angles of the rectangle are each 90 degrees.
So, it is clear that any two same side angles will be 90° + 90° = 180°
Meaning that same side angles of a non-square rectangle are supplemental.

It is not unusual to get 5 when a pair of dice is rolled.
Probability of an event is the ratio of number of favorable outcomes to the total number of outcomes. Probability is a measure of how likely an event is going to happen.
Given is that you get 5 when pair of dice is rolled.
Number of outcomes for sum of 5 = 4
The sample space for the outcomes for sum of 5 is {(1, 4), (2, 3), (3, 2), (4, 1)}.
So, we can write the probability of getting 5 as -
P(getting 5) = 4/36
P(getting 5) = 1/9
Although the probability of getting a 5 is low, but is not completely zero. So, it is not unusual to get 5.
Therefore, it is not unusual to get 5 when a pair of dice is rolled.

Not at all. In fact, there are 4 ways to roll it:
A 1 and a 4 or a 4 and a 1
A 2 and a 3 or a 3 and a 2
There are 36 possible ways you can roll 2 dice, so those 4 possibilities represent a 4/36 = 1/9 chance of rolling a total of 5 between two dice.

Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to help you remember the relationships between triangle sides and trig functions. These abbreviations tell you that ...
Sin = Opposite/Hypotenuse ⇒ sin(x) = b/c
Cos = Adjacent/Hypotenuse ⇒ cos(x) = a/c
Tan = Opposite/Adjacent ⇒ tan(x) = b/a
5x - 7y=40
O (1.-5)
O (1,5)
0 (-1,-5)
0 (-1,5)
Answer:
x=1 ,y=-5
Step-by-step explanation:
3x + 10y = 47
5x - 7y = 40
____________
21x + 70y = 329. equ 1
50x - 70y = 400. equ 2
subtract equ 1 from 2
=71x = 71
divide both sides by the 71
71/71 = 71/71
x = 1
_________
to find y
substitute x into either equ 1 or equ 2
am using equ 2
5x - 7y = 40
5(1) - 7y = 40
5 - 7y = 40
7y = 5 - 40
7y = -35
divide both sides by the coffecient of y
7y/7 = -35/7
y = - 5
