Answer:
B) 57.4+x=67
Step-by-step explanation:
We take the amount in the piggy bank. Then we take the amount spent and add it to the amount she has left. These two amounts should be equal
piggy bank = spent + left
67 = x + 57.40
Answer: Symmetric property of equality
This is the idea that if x = y, then y = x. We can swap the left and right sides of an equation, and still mean the same thing. The same applies to congruences as well.
Answer:
The measures of the three exterior angles would be 95, 160 and 105.
Answer:
<u>The correct answer is A. 1/216</u>
Step-by-step explanation:
Let's simplify the expression:
6^1/3 divided 6^10/3
6^1/3 = ∛ 6 and 6^10/3 = ∛ 6¹⁰, therefore:
∛ 6 / ∛ 6¹⁰
∛ 6 * 1/∛ 6¹⁰ (Flipping the reciprocal)
∛ 6 * 1/(∛ 6 * ∛ 6⁹)
1/∛ 6⁹ (Cancelling down ∛ 6 in the numerator and denominator)
1/6³ = 1/6 * 6 * 6 = 1/216
<u>The correct answer is A. 1/216</u>
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
