Answer:it will cost $1698
Step-by-step explanation:
You read online that a 15 ft by 20 ft brick patio would cost about $2,275 to have professionally installed. The area of the patio would be
15 × 20 = 300 square feet
It means that it costs $2275 to install 300 square feet of the patio professionally. Therefore, the cost of installing 1 square feet professionally would be
2275/300 = $7.58 per square feet
To estimate the cost of having a 14 by 16 ft, we would determine the total area.
Area = 16 × 14 = 224 square feet.
Therefore, the cost of installing 224 square feet professionally would be
224 × 7.58 = 1697.92
Approximately $1698
Answer:
CAB = CAD + DAB
161 = (5X + 7) + (3X - 6)
161 = 8X + 1
160 = 8X
160/8 = 8X/8
X = 20
C. If there is 23 people you would multiply x (the price) by 23. Since we know the price the expression is 17 x 23.
Since the time to failure distribution is
exponential, the distribution is F (n) = 1 – e ^ (-x/48)
The probability of failure between months 60
and 72 is the same as the probability that the battery will fail in 12 months,
since the exponential distribution is memoryless F (12) = 0.221

Answer:
3.75
Step-by-step explanation:
g(x)=60(1-0.5)^x, g(4)
g(4)=60(1-0.5)^4
g(4)=60(.5)^4
g(4)=60(0.0625)
g(4)=3.75
