Answer:
- Equation: 7.5 = ((2b-4) + b)
- length = 3.6667 ft
- width = 3.8333 ft
Step-by-step explanation:
perimeter = 2(length+width)
then:
15 = 2(a+b)
a = 2b - 4
a = length
b = width
solve:
15/2 = (a+b)
7.5 = ((2b-4) + b) ⇒ Equation that represents the perimeter of the
rectangle)
7.5 = 3b -4
7.5+4 = 3b
11.5 = 3b
b = 11.5/3
b = 3.8333
a = 2b - 4
a = 2*3.8333 - 4
a = 3.6667
Check:
15 = 2(3.8333 + 3.6667)
15 = 2*7.5

Answer:
Step-by-step explanation:
Given that despite a series of quality checks by a company that makes television sets, there is a probability of 0.07% that a newly purchased television set does not work properly.
Mean of X = np = 175
Var = np(1-p) = 174.8775
Std dev = 13.224
X is N(175, 13.224(
With continuity correction required prob
= P(X<200) = P(X<200.5)
= 0.973091
Using binomial
P(X<200) = 0.9659
Hello!! the answer is 3xy
Okay we'll start easy
46*93
We will take 6*3 which is 18.
40*3 which is 120
6*90 which is 540
40*90 which is 3600
Now add up those
18+120+540+3600 which is 4278
So the missing numbers.
3._00 is going to be 3600
5_0 is going to be 540
_20 is going to be 120
1_ is going to be 18
4._78 is going to be 4.278
Hope this helped. ^~^
