Okay to area is length x width which mean something had to be multiplied to get 7 and since width is less than 6 it leaves us with only option of 1x7 therefore the length is 7 while the width is 1
Answer:
the answer is b.
a little tip is if your between to answers and for exanple a and b pick b because d and b are more used for answers than a and c.
Step-by-step explanation:
All numbers? There are a countably infinite number of rational numbers and an uncountably infinite number of real numbers between 21 and 28; their sum goes to infinity.
If you’re talking about integers between 21 and 28 (not including the endpoints), there are six of them (22, 23, 24, 25, 26 and 27). Their sum is 147.
Answer: 0.2224
Step-by-step explanation:
Given: The proportion of adults need eye correction: p= 78%=0.78
Let X be a binomial variable that represents the number of adults who need eye correction.
Sample size of adults: n= 12
Binomial ditsribution formula:
Now, the probability that at least 11 of them need correction for their eyesight will be
Hence, the required probability = 0.2224
Step-by-step explanation:
-5x + 4y = 2
+ (9x - 4y = 6)
=> 4x = 8, x = 2.
Therefore -5(2) + 4y = 2, 4y = 12, y = 3.
The solution pair is (2,3).
