Answer:
12x-4
Step-by-step explanation:
15x*
5/4=12x
-5*4/5=4
Add the two together and you get
12x-4
2,376 square feet
**
Add the areas of all the sides of the shape.
A triangle's area: 1/2bh
The two triangles' area=24*9=216
The bottom side: 40*24=960
The two other sides: 30*40=1200
Add everything: 216+960+1200=2376
The probability of having lunch together is p = 40% = 0.4
The probability of not having lunch together is q = 1 - p = 0.6
Number of trials (days in a week) is n = 7
Let r = number of days in the week when Andy and Anna have lunch together.
Use th graphing calculator to obtain
P(6 of 7) = ₇C₆ (0.4)⁶(0.6) = 0.017
P(7 of 7) = ₇C₇ (0.4)⁷(0.6)⁰ = 0.002
Therefore
P(at least 6 of 7) = P(1 of 7) + P(2 of 7) + ... + P(6 of 7)
= 0.131 + 0.261 + 0.290 + 0.194 + 0.077 + 0.017
= 0.97 or 97%
P(at least 6 of 7) = 0.017 + 0.002 = 0.019 = 1.9%
P(exactly 6 of 7) = 0.017 or 1.7%
Answer:
The probability of having lunch at least 6 days per week is 0.019 or 1.9%.
The probability of having lunch exactly 6 times is 0.017 or 1.7%
Answer:
y=-4x+3
Step-by-step explanation:
4x + y=3
4x gets switched to the other side so that it is by its self
which then the equation is going to be y=-4x+3 bc the sin changes
Answer:
1 1/2 + 2/5
3/2 + 2/5 I changed the first fraction from a mixed fraction to an improper fraction
5/5( 3/2 ) + 2/2(2/5) I did this to make the denominators the same
15/10 + 4/10
19/10
1 9/10 = Answer
