An oil company conducts a geological study that indicates that an exploratory oil well should have a 20% chance of striking oil.
A. What is the probability that the first strike comes on the third well drilled?
B. What is the probability that the third strike comes on the seventh well drilled?C. What is the mean and the variance of the number of bad wells, if the oil company wants toset up three producing wells?
Answer:
a) 0.128
b) 0.049152
Step-by-step explanation:
a) first strike comes on the third well drilled
=> two non-strikes and a strike
P = (0.8)^2 * (0.2)
= 0.128
b) third strike comes on the seventh well drilled
=> two strikes in first six wells and a strike in seventh
P = 6C2 * (0.2)^2 (0.8)^4 * (0.2)
= 0.049152

Based on this estimation, determine the probability for each of the following scenarios. Round your answers to three decimal places.
In a survey of 22 Americans, exactly 15 of them will respond that they love beets.
Answer: 13% or 0.1314
Step-by-step explanation: Binomial PDF on the calculator or by hand its
22 nCr 15 (0.60)^15(1-0.6)^7 = 0.131378
The probability in a survey of 22 Americans where exactly 15 of them will respond that they love beets given that 60% of American love beets is 0.131.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
The binomial probability distribution:
[tex]^nC_r p^r (1 - p)^{n - r}[/tex]
Now,
p = 60% = 60/100 = 0.6
1 - p = 1 - 0.6 = 0.4
n = 22
r = 15
Now,
[tex]^nC_r p^r (1 - p)^{n - r}[/tex]
= [tex]^{22}C_{15}(0.6)^{15} (0.4)^{22 - 15}[/tex]
= [tex]^{22}C_{15}(0.6)^{15} (0.4)^7[/tex]
= 0.1313
Thus,
The probability is 0.131.

Answer:
The answer is D
Step-by-step explanation:
Which multiplication problem does the model represent?
A- 1/8 times 2
B- 7/8 times 2
C- 1/2 times 4
D- 1/4 times 8
The correct answer would be D- 1/4 times 8
This is the correct answer because if you look at the model, it shows 2 blocks of 1, and then 8 blocks of 1/4, which both equal 2, and the model does not say anything about the top row, only the bottom, and after process of elimination, you would be left with 1/4 times 8

1. A certain manufacturing process to build phone batteries results in the production of defective batteries at a rate of 5% (0.05). Suppose that 10 batteries are produced. a. Find the expected number of defective batteries. b. Find the variance and standard deviation in the number of defective batteries. c. Find the probability that at least 1 battery is defective.
Answer:
0.5 ; 0.475 ; 0.689 ; 0.4013
Step-by-step explanation:
Given that:
Rate of production of defective batteries p = 0.05
Number of batteries produced (n) = 10
The expected number of defective batteries = mean = n * p = 10 * 0.05 = 0.5 batteries
Variance of defective batteries :
Var(X) = n * p * q ; q = 1 - p
Hence,
Var(X) = 10 * 0.05 * 0.95 = 0.475
Standard deviation (X) = sqrt(variance) = sqrt(0.475) = 0.689
Probability that atleast 1 battery is defective :
Using the binomial probability function
P(x ≥ 1) = 1 - p(x = 0)
= 1 - q^n
= 1 - 0.95^10
= 1 - 0.59873693923837890625
= 0.40126306076162109375
= 0.4013

The scale factor of a model plane to the actual plane is 1 to 25.
Find the wing area of the model if the wing area of the actual plane is 300 ft2
.
Step-by-step explanation:
Length on model : Length on actual = 1 : 25
=> Area on model : Area on actual
= 1² : 25² = 1 : 625.
Therefore area on model = 300ft² * (1/625) = 0.48ft².

Given the third term is 12 and the rate of change is 3. What is the 5th term
Answer:
The 5th term:
a₅ = 18
Step-by-step explanation:
We know that Arithmetic sequences have a constant rate of change.
Given
a₃ = 12common difference = rate pf change = d = 3The nth term of the Arithmetic sequence with a₁ and 'd' is defined as
aₙ = a₁ + (n-1)d
Where
a₁ is the first term
d is the common difference
as
a₃ = 12
d = 3
so
Plug in n=3
a₃ = a₁ + (3-1)d
Now Plug in a₃ = 12 and d = 3
12 = a₁ + (3-1)3
12 = a₁ + 2(3)
12 = a₁ + 6
a₁ = 6
so
Formula to find the 5th term
a₅ = a₁ + 4d
Plug in a₁ = 6 and d = 3
a₅ = 6 + 4(3)
a₅ = 18
Therefore, the 5th term:
a₅ = 18

Explain whether △ABC is congruent to △XYZ according to the angle side angle (ASA) congruence criteria.
Answer:
∆ABC and ∆XYZ cannot be proven to be congruent to each other according to the Angle-Side-Angle (ASA) Congruence criteria.
Step-by-step explanation:
The Angle-Side-Angle (ASA) Congruence criteria says that two triangles are congruent to each other if two angles and an included side of one triangle is congruent to two corresponding angles and a corresponding included side of the other triangle.
In the diagram given, the two angles were given (<B and <C), however, the side given (side AB) does not lie in the middle of <B and <C, hence it is NOT AN INCLUDED SIDE. The same applies to ∆XYZ.
Therefore, ∆ABC and ∆XYZ cannot be proven to be congruent to each other according to the Angle-Side-Angle (ASA) Congruence criteria.

A family eats at a restaurant and the meal is $65, and they leave a tip of 20% of the price of the meal. What is the total with the meal and the tip?
♡ Answer ♡
$78
♡ Step-by-step explanation ♡
In the problem, it states that the family's meal is $65. At the same time, it is also mentioned that the tip is 20% of the price of their meal. This means that the tip is 20% of $65. In order to figure out the total price with the meal and the tip, we must multiply 20% by $65 in order to get the tip, and add $65 for the price of the meal. The sum will be your answer.
As stated earlier, the first step to this question is to multiply $65 by 20%. 20% in decimal form is 0.2 0.2*$65 equals $13. So, the family left a $13 tip.
The other step in finding the overall amount of money the family used is to add $65 to our previous answer. In this case, our previous answer is $13. We must add $65 to $13 in order to find the total price. $65+$13 is $78.
So, the total (with the meal and the tip) is $78.
