A garage door code has 5 digits. If no digit is repeated, how many codes are possible?
Hint: the possible digits are 0-9
Answer:
There are 30240 possible codes.
Step-by-step explanation:
For the first digit, there are 10 number choices possible:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9
For the second digit, 9 number choices, because one of the digits cannot be repeated.
For the third, 8 number choices, because two of the digits cannot be repeated.
For the fourth, 7 number choices, because three of the digits cannot be repeated.
For the fifth, 6 number choices because four of the digits cannot be repeated.
Now multiply all the numbers, and you can see that there are 10*9*8*7*6, or 30240 codes possible.

Answer:
x = 10
y = 10√2
Step-by-step explanation:
Reference angle = 45°
Opposite = 10
Adjacent = x
Hypotenuse = y
Recall: SOHCAHTOA
✔️Apply TOA to find x:
Tan 45 = Opp/Adj
Tan 45 = 10/x
x = 10/Tan 45
x = 10/1 (tan 45 = 1)
x = 10
✔️To find y, apply SOH:
Sin 45 = Opp/Hyp
Sin 45 = 10/y
y = 10/Sin 45
y = 10/(1/√2) (sin 45 = 1/√2)
y = 10 × √2
y = 10√2
A rectangular plot of land has an area of 8/3 square miles and a length of 3/5 mile. What is the width of the plot of land? F.9/40 mi G.5/8 mi H.1 3/5 J.4 4/9
Answer:
Width = x mile = 4 4/9 mile
J.4 4/9
Step-by-step explanation:
Area of a rectangle = length × width
Area of the rectangular plot = 8/3 square miles
Length = 3/5 mile
Width = x mile
Area of a rectangle = length × width
8/3 = 3/5 * x
8/3 = 3/5x
x = 8/3 ÷ 3/5
Multiply 8/3 by the reciprocal of 3/5
x = 8/3 × 5/3
= (8*5) / (3*3)
x = 40/9
x = 4 4/9 mile
Width = x mile = 4 4/9 mile
The result of a random survey showed that 40 out of 75 people plan to vote for Mr. Best for a position on the local store school board which is the best prediction of the number of people who vote for Mr. Busan if 3000 people vote
Answer: 1,600 people
Step-by-step explanation:
The survey showed that 40 out of 75 people would vote for Mr. Best.
Convert this figure to a percentage so that you can use it to find out the number of people that would vote for him if numbers were larger:
= 40 / 75
= 53.33%
If 3,000 people voted, 53.33% would vote for Mr. Best which is:
= 3,000 * 53.33%
= 1,599.9
= 1,600 people

A sample of 40 people owned an average of 1.35 hats. It is known from a previous study that the population standard deviation of hat ownership is 0.63 hats. Construct a 95% confidence interval.
Answer:
(1,155, 1.545).
Step-by-step explanation:
From Normal distribution tables the z score for 95% CI = 1.96.
Confidence Interval
= 1.35 +/- 1.96 * 0.63/√40
= 1.35 +/- 0.195
= (1,155, 1.545).

HELP ASAP!!draw dotted lines to show the parallelogram or rectangle that can be used to find the area of each triangle then find the area of each triangle
Answer:
The rectangle that we could use to find the area of the yellow triangle, is a rectangle of length = 12cm and a width = 8 cm. (A image of this can be seen below).
Remember that:
The area of a rectangle of length L and width W is:
A = W*L
The area of a triangle rectangle with catheti a and b is:
A = a*b/2
Then the area of the rectangle of length = 12cm and width = 8cm is:
A = 12cm*8cm = 96 cm^2
Now we need to subtract twice the area of a triangle rectangle of catheti a = 8cm and b = 6cm
(one cathetus is 6cm because is exactly half of the length of the rectangle)
The area of each one of these triangle rectangles is:
A' = 8cm*6cm/2 = 24cm^2
The area of the yellow triangle will be:
A = A - A' = 96cm^2 - 2*24cm^2 = 48cm^2
3. If x and y vary directly, and x = 60 when y = 5, what is the value of у when x = 36 ?
Answer:
y = 3
Step-by-step explanation:
Use the direct variation equation, y = kx
Plug in 60 as x and 5 as y, and solve for k
y = kx
5 = k(60)
1/12 = k
So, the equation is y = 1/12x
Plug in 36 as x and solve for y
y = 1/12x
y = 1/12(36)
y = 3
So, when x = 36, y = 3
Members of a school sports team are raising money by selling custom water bottles at school activities. They plan to sell each bottle for $13. Each bottle costs them $6. They spend $40 for advertising. Use n to represent the number of bottles they sell. Multiply this by the money they make for each bottle, then subtract the advertising cost. Which expression represents the money that the group raises? O A. 40 - (13 - 6)n O B. (13 - 6) n - 40 O C. 13n - 6 - 40 D. 13-on-40
Answer:
B. (13 - 6)n - 40
Step-by-step explanation:
If each bottle costs them $6 and they are selling each one for $13, the amount of money they make for each bottle can be represented by (13 - 6)n
This is because this finds the profit per bottle, then multiplies it by n, which is the number of bottles they sell.
Then, since they spent $40 on advertising, subtract 40 from this.
The expression will be (13 - 6)n - 40.
The correct answer is B. (13 - 6)n - 40
The expression represents the money that the group raises is (13-6)n - 40
What is expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
According to the question
Members of a school sports team are raising money by selling custom water bottles at school activities.
Let number of bottle they sell = n
Selling price of a bottle = $13
Now ,
Selling price of n bottle = $13n
Cost price of a bottle = $6
Now ,
Cost price of n bottle = $6n
Money spent on advertising = $40
Total they spent on bottles = $6n + $40
Therefore,
Money they raise in expression = 13n - 6n - 40
= (13-6)n - 40
Hence, The expression represents the money that the group raises is (13-6)n - 40
