1. Consider the tree diagram in the picture attached.
2 Each of the games picked can be a W (win) or a L (lose), the chances are equal
3. All that could happen in 4 picked games is shown in the picture:
2 w 2 l can happen in the following 6 ways: {(W,W,L,L)(W,L,W,L)(W,L,L,W)(L,W,W,L)(L,W,L,W)(L,L,W,W)}
4. P(2W,2L)=6/16=3/8
Answer:
the third one
Step-by-step explanation:
y represents the number plus 5 and the x represents the other number
Answer:
The parallelogram is not rectangle because the sides of the parallelogram do not meet at right angles.
Step-by-step explanation:
Given the parallelogram with sides 20 and 21 units with diagonal length 28 units.
we have to tell it is a rectangle or not.
The given parallelogram is rectangle if the angle at vertices are of 90° i.e the two triangle formed must be right angles i.e it must satisfy pythagotas theorem


Not verified
∴ The sides of the parallelogram do not meet at right angles.
Hence, the parallelogram is not rectangle because the sides of the parallelogram do not meet at right angles.
Option B is correct
Answer:
x=4 and y=4
Step-by-step explanation:
using simultaneous equations by elimination method
Answer:
e. $44.20
Step-by-step explanation:
1. add all of the percentages together and subtract them by 100. this will give the percentage she wasted on food: 17%
2. convert 17% into a decimal: .17
3. multiply 260 by .17 this should give you 44.2
