Answer: 0.375
Step-by-step explanation:
Given: The difference between actual and predicted weekly sales of a company follows a uniform distribution between -$4000 and $4000.
Probability density function: [tex]f(x)=\dfrac{1}{b-a}=\dfrac{1}{4000-(-4000)}=\dfrac{1}{8000}[/tex]
The probability that the actual sale is within $1500 of the predicted sale = [tex]\int^{1500}_{-1500}f(x)dx=\int^{1500}_{-1500}\dfrac{1}{8000}dx=\dfrac{1}{8000}[x]^{1500}_{-1500}\\\\= \dfrac{1}{8000}(1500-(-1500))\\\\= \dfrac{1}{8000}(3000)=0.375[/tex]
Hence, Required probability =0.375

Step-by-step explanation:
Answer:
6:2
Step-by-step explanation:
This simply means for every 6 triangles there are going to be 2 circles, so if you had 12 triangles there would be 4 circles.
So think of it kinda like:
6 triangles = 2 circles and so on.

A bakery sells different packages of muffins. The number of muffins, x, and the price in dollars, y, of their packages of muffins are given in the ordered pairs below. The set of ordered pairs is a relation that is also a function.
{(1,2),(2,3),(4,5),(6,7),(12,13)}
The bakery is considering adding a new package of muffins. which ordered pairs would make the relation NOT a function? Choose all that are correct.
a. (10,13)
b. (6,8)
c. (8,12)
d. (4,3)
e. (24,18)
Answer:
A,D,B
Step-by-step explanation:
Those have the same as the ordered pairs in the question. Having 2 ordered pairs with the same variables would make them not a function.
A relation may or may not be a function.
b. (6,8) and d. (4,3) would make the relation not a function
The ordered pair is given as:
[tex]\mathbf{(x,y) = \{(1,2),(2,3),(4,5),(6,7),(12,13)\}}[/tex]
For a relation to be a function, all the x-values must be unique (i.e. no repetition)
From the list of given options, the x values of options (b) and (d) already exist in the ordered pair i.e. (6,7) and (4,5)
This means that: (b) and (d) would make the relation not a function

Candice spent 3 ⅘ hours, and Shane spend 2 ⅒ hours at track practice over the weekend. How many more hours did Candice spend than Shane at track practice?
Answer:
1 7/10
Step-by-step explanation:
2 1/10 - 3 4/5= 1 7/10 but if you don't understand this then...
Take the wholes and minus both of them which makes 1 (BTW this will be your whole number) Then convert 4/5 into tenths (easier way: draw 4 circles and cut them in half, then count all the halves. That will be your answer, in this case my answer would be 8/10) Now since Shane spent 2 1/10 hours on track we are going to take the fraction beside the whole number (AKA 1/10) and minus it by our 4/5 (AKA 8/10) Now we have 7/10. Our answer would be 1 7/10.

The probability that a certain brand of watch is defective is 6%. If 2 watches of this brand are randomly selected, then what is the probability that: None will be defective
Answer: The probability that: None will be defective = 0.8836
Step-by-step explanation:
Let x be the number of defectives watch.
As per given: p= 6%= 0.06 (probability of defective)
Sample size : n= 2
Binomial probability distribution formula : [tex]P(X=x)=^nC_xp^x(1-p)^{n-x}[/tex]
P(No defective)=P(X=0)
[tex]^{2}C_0(0.06)^0(1-0.06)^{2} =(1)(0.94)^2=0.8836[/tex]
Hence, The probability that: None will be defective = 0.8836

Ayana and Leah were trying to solve the equation:
(x- 5)^2 + 4 = 16
Ayana said, "I'll take the square root of both sides and rewrite the equation as (x-5) +2 = 4. Then I'll solve
for x"
Leah said, "Ill isolate (x - 5)^2 by subtracting 4 from both sides of the equation. Then I'll solve by taking the
square root."
Answer:
only leahs
Step-by-step explanation:
ayana is wrong
The statement given by Lean that "Ill isolate (x - 5)^2 by subtracting 4 from both sides of the equation. Then I'll solve by taking the square root." is correct way of solving an equation.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The given equation can be solved as shown below,
(x- 5)² + 4 = 16
Subtract 4 from both the sides of the equation,
(x- 5)² + 4 -4 = 16 - 4
(x- 5)² = 12
Taking square root of both the sides of the equation,
√(x- 5)² = √12
x - 5 = √12
Add 5 on both the sides of the equation,
x - 5 + 5 = √12 + 5
x = √12 + 5
Now, if both Ayana and Leah process of solving is compared with the solution above, it can be concluded that Leah is using the correct method to solve the equation.
Hence, the statement given by Lean that "Ill isolate (x - 5)^2 by subtracting 4 from both sides of the equation. Then I'll solve by taking the square root." is correct way of solving an equation.

Answer:
51514.88
Step-by-step explanation:
thats the answer
Answer:
51.515
Step-by-step explanation:
When you round a number to three decimal places, not only you need to cut your decimals to the third one, but need to examine the following (fourth decimal in this case) to decide if you need to round using the digit in the third decimal that appears, or use the following digit.
The rule is, if the following decimal is any of the following digits: 5, 6, 7, 8, or 9, you use in the rounding place one digit ABOVE the one that appears .
In our case, 51.51488 you look at the fourth decimal, and since it is an "8", you change the third decimal "4" into a "5". Leaving the following rounding:
