Answer:
$20 per sweater.
Step-by-step explanation:
It is given that,
A store buys 7 sweaters for $42 and sells them for $182.
We need to find how much profit the store make per sweater.
The amount the store bought the sweaters fr is calculated as follows :
$182- $42 = $140
Profit the store made per sweater is given by :

Hence, the store will make $20 per sweater.
Answer:


Step-by-step explanation:
Given

Number of Girls : 0 ----> 1 -----> 2 ------->3
Number of Families: 112 -> 314 --> 382 ---> 192
Solving (a): At most one girl
From the table, the number of families with at most one girl is: 112 + 314
i.e.
Number of Girls : 0 ----> 1
Number of Families: 112 -> 314
So, we have:


The probability is then calculated as:



Solving (b): More girls
From the table, the number of families with more girl is: 382 + 192
i.e.
Number of Girls : -----> 2 ------->3
Number of Families: --> 382 ---> 192
So, we have:


The probability is then calculated as:



Answer:
x = 80
Step-by-step explanation:
In a quadrilatoral the interior angle sum always adds up to 360 degrees so to find x you would add all of the interior angle sums and subtract that from 360
115 + 95 + 70 + x = 360 just add the like terms
280 + x = 360 now subtract 280 from both sides so x is alone and you can figure out its value
x= 80
