Answer:0.29
Step-by-step explanation:
An average of six cell phone thefts is reported in San Francisco per day. This means our mean value, u = 6
For poisson distribution,
P(x=r) = (e^-u×u^r)/r!
probability that four cell phones will be reported stolen tomorrow=
P(x=4)= (e^-6×6^4)/4!
= (0.00248×1296)/4×3×2×1
= 3.21408/24=
0.13392
P(x=5)= (e^-6×6^5)/5!
= (0.00248×7776)/5×4×3×2×1
= 19.28448/120
= 0.1607
probability that four or five cell phones will be reported stolen tomorrow
= P(x=4) + P(x=5)
= 0.13392 + 0.1607
= 0.294624
Approximately 0.29
Answer:
k = -2
Step-by-step explanation:
f(x) = (x − h)² + k
(h, k) is the (x, y) coordinate of the vertex
For a vertex of (4, -2)
h = 4
k = -2
Answer:
Let the measure of each side of the square be " x " cm.
then ,
area of square = x²
After we folded the square into a rectangle ,
length of rectangle = x
breadth of rectangle = x/2
perimeter of rectangle = 36 cm
hence ,
side of square = 12 cm
therefore ,
area of square = 12 × 12 = 144 cm²

Answer:
The answer is "y < 2x - 4".
Step-by-step explanation:
Write in <u>slope-intercept</u> form, the formula is "y = mx + b"
Answer: Jason likely MADE an error when working the equation in his notebook because ONLY THE Y-INTERCEPT MATCHES the slope and the y-intercept of the equation he wrote.
