Chris had a job walking dogs on the weekends. He earned $8.75 per dog. He walked 5 dogs a week for 7 weeks. How much money did Chris earn?
Answers
Answer:
Chris's total earning will be: $306.25
Step-by-step explanation:
Given:
Total number of dogs = d = 5
Number of weeks = w = 7
Cost for walking per dog = c = $8.75
First of all, we will calculate his per week cost of walking 5 dogs
Per week cost of walking 5 dogs = d*c = 8.75*5 = $43.75
Then for the cost of 7 weeks, the amount of one week will be multiplied by 7
Total earning will be:
Hence,
Chris's total earning will be: $306.25
Answer:
he should be making $306.25
Step-by-step explanation:
what i did was multiply his $8.75 a dog by 5 then multiply it by the 7 weeks

Answer:
0.0108
Step-by-step explanation:
Let X denote the number of uranium fission tracks occurring on the average 5 per square centimetre.We need to find the probability that a 2cm² sample of this zircon will reveal at most three tracks. X follows Poisson distribution, λ = 5 and s = 2.
k = λs = 5×2 = 10
Since we need to reveal at most three tracks the required probability is:
P (X≤3) = P (X =0) + P (X =1) + P (X =2) + P (X =3)
P (X≤3) = (((e^-10) × (10)⁰)/0!) + (((e^-10) × (10)¹)/1! + (((e^-10) × (10)²)/2! + (((e^-10) × (10)3)/3!
P (X≤3) = 0.0004 + 0.0005 +0.0023 +0.0076
P (X≤3) = 0.0108
Therefore, the probability that a 2cm² sample of this zircon will reveal at most three tracks is 0.0108
Answer:
p(x = 3, λ = 5) = 0.14044
Step-by-step explanation:
Given
λ = 5 (the average number of tracks per square centimeter)
ε = 2.718 (constant value)
x = 3 (the variable that denotes the number of successes that we want to occur)
p(x,λ) = probability of x successes, when the average number of occurrences of them is λ
We can use the equation
p(x,λ) = λˣ*ε∧(-λ)/x!
⇒ p(x = 3, λ = 5) = (5)³*(2.718)⁻⁵/3!
⇒ p(x = 3, λ = 5) = 0.14044

Step-by-step explanation:
Which system of equations has infinitely many solutions?
4 x + 2 y = 5 // -4x - 2y = 1
-10x + y = 4 // 10x - y = -4.
-8x + y = 2 // 8x-y = 0.
-x + 2 y = 6 // 7x-2y = 12.
It's important to know that a linear system of equations has infinitely many solutions when both equations represents the same line, that means one line is on top of the other one, that's why the shared infinite points.
In this case, notice that if we compare the second system, you would find that both equations are the same,
If we multiply the first equation by -1
Which means the system has infinitely many solutions, because both equations represent the same line, so the shared all possibles points.
Therefore, the right answer is the second choice.

Answer:
A. -0.87
Step-by-step explanation:
The correlation coefficient is a measure of the strength and nature of the linear relationship between two variables, one dependent and one independent. This coefficient takes values between -1 and 1, indicating with its sign whether the relationship is direct or inverse between the variables involved and with its absolute value indicates the strength of the linear relationship between them. A coefficient with absolute value close to 1 indicates great strength and better fit.
Conclusion: The best coefficient, of the propuetso in the problem, is that of -0.87, which indicates a strong relationship between the variables, a good fit and an inverse relationship between them.
