Answer:
$133.9
Step-by-step explanation:
<em>I believe the unit being used in the problem above is dollar ($).</em>
The problems above can be easily solved by using <em>multiplication operation </em>and <em>addition operation </em>afterwards.
Given: Bermuda sod = <em>$2.25 per piece</em>
Zoysia sod = <em>$3.32 per piece</em>
Let's solve for the cost of buying the Zoysia sod.
20 pieces x $3.32 per piece = $45 dollars
The total cost of the Zoysia sod that Becky will buy is $66.4.
Next, let's solve for the cost of buying the Bermuda sod.
30 pieces x $2.25 per piece = $67.5
The total cost of the Bermuda sod that Becky will buy is $67.5.
Let's get the total cost.
$66.4 + $67.5 = $133.9
<em>It will cost Becky $133.9 to buy 20 pieces of Zoysia sod and 30 pieces of Bermuda sod.</em>
Answer:
If there are 1000 customers in the store one week, how many will purchase exactly one of these items
1000 CUSTOMERS*28%=280
Step-by-step explanation:
A The event that a persons buys a suit
B The event that a person buys a shirt
C The event that a person buys a tie
P(A)= 22%
P(B)= 30%
P(C)= 28%
P(AB)=
11%
P(AC)=
14%
P(BC)=
10%
P(ABC)=
6%
A u B u C Is the event that any item is bougth
AC u AC u BC Is the event that any two events occured
So the wanted probability is
P[(A u B u C )(AB u AC u BC)^c
P[(A u B u C )=P(AB)+ P(BC)+P(BC)
P[(A u B u C ) =0.22+0.30+0.28-0.11-0.14.-0.10+0.06
=0,51
0,51=+0,23+P[(A u B u C )(AB u AC u BC)^c
=0,28
1000 CUSTOMERS*28%=280
Answer:
You can not tell unless you have information about the relationship between the small and large boxes (for example, a large box is 2 times the weight of a small box) You can only tell that a small box and a large box's weight together is 34.5 kilograms.
Step-by-step explanation:
3L + 5S = 135
9L + 7S = 279
12L + 12S = 135 + 279
12(S+L) = 414
S+L = 34.5

Answer:
The sampling technique used is convenience sampling.
Step-by-step explanation:
Convenience sampling technique is a method of non-probability sampling that is done using the most easiest sample or the most convenient sample.
For instance, sampling the people of our neighborhood, or school or company, etc.
This type of sampling is known as non-probability sampling because each individual\participant does not have a specific probability of selection. Whereas in case of probability sampling each participant has an equal probability of being selected.
Survey that are conducted through online portals or online survey use samples that are quite easy to collect. The sample collected through online surveys is convenience sample.
The survey conducted to determine how many people were in favor of stricter gun control uses a convenience sampling technique. As it uses the most easy source to collect the sample.
Thus, the sampling technique used is convenience sampling.
