Answer:
0.294
Step-by-step explanation:
The number of possible outcomes for 2 consecutive days is 2 (Friday, Saturday and Saturday,Sunday).
Prob( Friday, Saturday has rain) = 0.70*0.70* 0.30) = 0.147 (No rain Sunday)
Prob( Saturday/Sunday has rain) = 0.30*0.70*0.7) = 0.147 (No rain Friday)
Required Probability = 2*0.147
= 0.294.
Answer:
-5
Step-by-step explanation:
Point P represents -5. You can see that the line counts up in increments of 2. P is in between -6 and -4. It must be -5.
Answer:
Step 1: Set the expression inside the square root greater than or equal to zero. Step 2: Solve the equation found in step 1. In this case, we divided by a negative number, so had to reverse the direction of the inequality symbol. Step 3: Write the answer using interval notation.
Answer:
At 25 = 6.8612mm
At 50 years = 5.422mm
Step-by-step explanation:
Equation,
d = 2.115Logₑa + 13.669
d = diameter of the pupil
a = number of years
Note : Logₑa = In a (check logarithmic rule)
d = 2.115Ina + 13.669
1. At 25 years,
d = -2.115In25 + 13.669
d = -2.115 × 3.2188 + 13.669
d = -6.807762 + 13.669
d = 6.8612mm
At 25 years, the pupil shrinks by 6.86mm
2. At 50 years,
d = -2.1158In50 + 13.669
d = -2.1158 * 3.912 + 13.669
d = -8.2770 + 13.699
d = 5.422mm
At 50 years, the pupil shirks by 5.422mm
To save this question, I had to plug in the values into the equation.
Solving for Logₑa might be difficult, so instead I used Inx which is the same thing. Afterwards, i substituted in the values and solve the equation for each years.
