Answer:
s = 41 cm
Step-by-step explanation:
Since all the sides on a square are equal, we can use this formula for perimeter: P = 4s
Plugging in 164 gives us 164 = 4s, where solving for s gives us s = 41

A bag has 4 red marbles, 4 blue marbles,
and 2 green marbles. Jessie draws a
.
marble from the bag at random, notes the
color, and then replaces the marble. She
then draws a second marble at random.
What is the probability that both the
marbles are green?
A.) 1/45
B.) 1/25
C.) 1/5
D.) 2/5
Answer:
Your answer would be:
C.) 1/5
Since there are 10 marbles in total that mean the answer would be equal to a value with a denominator of 10.
Since 2 out of 10 are green that means there is a 2/10 probability that Jessies will pick a green marble.
2/10 = 1/5
2/10's are equivalent to 1/5

What is the value of x in the figure?
Enter your answer in the box.
Answer: 34 degrees
Step-by-step explanation:
Since the sum of the measure of x and 56 = 90 because a right angle is 90 degrees, we can solve for x.
x + 56 = 90
x = 34
Answer:
34º
Step-by-step explanation:
the box in the graph means a 90º angle. if 56 and x make up 90º, its a simple subtraction problem. 90º-56º=34º.

Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. (Hint: Let (x,y) be the unknown endpoint. Apply the midpoint formula, and solve the two equations for x and y.) midpoint (-24,15), endpoint (- 15,13) The other endpoint is (Type an ordered pair.)
Answer:
The other endpoint is (-33, 17)
Step-by-step explanation:
The rule of the mid-point of a segment whose endpoints are
([tex]x_{1}[/tex], [tex]y_{1}[/tex]) and ([tex]x_{2}[/tex], [tex]y_{2}[/tex]) is
[tex](x_{M},y_{M}) = (\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})[/tex]In our question
∵ The coordinates of the endpoints of a segment are (-15, 13) and (x, y)
∴ [tex]x_{1}[/tex] = -15 and [tex]x_{2}[/tex] = x
∴ [tex]y_{1}[/tex] = 13 and [tex]y_{2}[/tex] = y
∵ The coordinates of the mid-point of this segment are (-24, 15)
∴ [tex]x_{M}[/tex] = -24 and [tex]y_{M}[/tex] = 15
→ Use the rule of the mid-point to find x and y
∵ [tex]-24=\frac{-15+x}{2}[/tex]
→ Multiply both sides by 2
∴ -48 = -15 + x
→ Add 15 to both sides
∴ -33 = x
∵ [tex]15=\frac{13+y}{2}[/tex]
→ Multiply both sides by 2
∴ 30 = 13 + y
→ Subtract 13 from both sides
∴ 17 = y
∴ The other endpoint is (-33, 17)

A high percentage of people who fracture or dislocate a bone see a doctor for that condition. Suppose the percentage is 99%. Consider a sample in which 300 people are randomly selected who have fractured or dislocated a bone. (i) What is the probability that exactly five of them did not see a doctor? (4 marks) (ii) What is the probability that fewer than four of them did not see a doctor? (5 marks) (iii) What is the expected number of people who would not see a doctor? (5 marks)
Answer:
(i) 0.15708
(ii) 0.432488
(iii) 3
Step-by-step explanation:
Given that, 99% of people who fracture or dislocate a bone see a doctor for that condition.
There is only two chance either the person having fracture or dislocation of bone will either see the doctor or not.
As per previous data, if one person got a fracture or dislocation of bone, the chance of seeing the doctor is 0.99. Assuming this chance is the same for every individual, so the total number of people having fractured or dislocated a bone can be considered as Bernoulli's population.
Let p be the probability of success represented by the chances of not seeing a doctor by any one individual having fractured or dislocated a bone.
So, p=1-0.99=0.01
According to Bernoulli's theorem, the probability of exactly r success among the total of n randomly selected from Bernoulli's population is
[tex]P(r)=\binom{n}{r}p^r(1-p)^{n-r}\cdots(i)[/tex]
(i) The total number of persons randomly selected, n=400.
The probability that exactly 5 of them did not see a doctor
So, r=5 , p=0.01
Using equation (i),
[tex]P(r=5)=\binom{400}{5}(0.01)^5(1-0.01)^{400-5}[/tex]
[tex]=\frac{400!}{(400-5)!\times 5!}(0.01)^5(0.99)^{395}[/tex]
=0.15708
(ii) The probability that fewer than four of them did not see a doctor
[tex]=P(r<4)[/tex]
[tex]=P(r=0)+P(r=1)+P(r=2)+P(r=3)[/tex]
[tex]=\binom{400}{0}(0.01)^0(0.99)^{400}+\binom{400}{1}(0.01)^1(0.99)^{399}+\binom{400}{2}(0.01)^2(0.99)^{398}+\binom{400}{3}(0.01)^3(0.99)^{397}[/tex]

How do you find the quotient of positive and negative decimals.
Answer:
Ok, so we know that you can't simply divide a decimal as it is (if you're using long division)
For example, let's take the quotient of 2.2 and -22
22÷ -2.2
so to get it into a whole number, multiply each value by 10 to get rid of decimal point
220 ÷ -22
when you divide, you are left with negative ten. Remember when you divide a negative and a positive number together, the result will always be negative
hope you understand now ;-)
a Show that the sum of any three
consecutive even integers is a multiple of 6.
b) Hence, or otherwise, work out what the
values of three consecutive even integers
must be if their sum is 6000.
Answer:
Below.
Step-by-step explanation:
a) Let the numbers be n, n + 2 and n + 4
Sum = n + n + 2 + n + 4
= 3n + 6.
As n must be even (2, 4, 6 and so on) , 3n must be divisible by 6 and 3n + 6 is divisible by 6 also.
b) 3n + 6 = 6000
3n = 5994
n = 5994/3 = 1998
So the numbers are 1998, 2000 and 2002.

(25 -5√7)/3 ≈ 3.924 inches
Step-by-step explanation:
After removing squares from the corners and folding up the sides, the open-top box will have dimensions ...
x × (20 -2x) × (30 -2x)
The maximum value for this cubic expression in the domain 0 < x < 10 is found easily by a graphing calculator to be at x = 3.924 inches.
__
You can solve this by expanding the cubic and finding the solution that makes its derivative equal to 0.
V(x) = 4x^3 -100x^2 +600x
The derivative is ...
V'(x) = 12x^2 -200x +600 = 0
Dividing by 12, we have ...
x^2 -50/3x +50 = 0
Completing the square, we get the form ...
(x -25/3)^2 = -50 +(25/3)^2 = (-450 +625)/9 = 175/9
Taking the square root gives ...
x -25/3 = ±(5√7)/3
The solution in the desired range is ...
x = (25 -5√7)/3 ≈ 3.924 . . . inches
_____
Additional comment
We limit the value of x to half the width of the cardboard material, as any longer cuts would overlap to create a negative box dimension. The graph shows the maximum volume to be about 1056.3 cubic inches. Box dimensions would be 3.924 in deep by 12.153 in by 22.153 in.
__
The generic solution can be found using a similar procedure. For cardboard dimensions a×b, it will be ...
x = ((a +b) -√((a -b)² +ab))/6
If it takes 11.75 gallons of gas to refuel the car tim rented, how much extra should he expect to pay because he forgot to get gas? a. $26.44 b. $31.44 c. $52.88 d. $57.88
The extra amount that Tim is expected to pay is approximately given by: Option D: $57.88
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
For this case, the question is missing the fact that the size of the tank is 11.75 gallon and a gallon of gas costs $4.50.
So, the total cost of 11.75 gallon of gas is:
Cost of 11.75 gallon gas = 11.75 * 4.50 = 52.875 (in dollars)
Also from the question, the cost of refueling a vehicle is $5.00.
So, the total cost for refueling the car of Tim is:
Total cost = cost of gas + cost of refueling the car
Total cost = 52.875 + 5.00
Total cost = $57.875 ≈ $57.88
Thus, the extra amount that Tim is expected to pay is approximately given by: Option D; $57.88
