A personal identification number (PIN) consists of 3 numbers 0 – 9. What's the probability someone's PIN number consists of only 1 number. For example 000, 111, 222, etc.
Answer: [tex]0.34[/tex]
Step-by-step explanation:
given data:
numbers contained in pin = 3
numbers pin can be gotten from = 0-9
solution:
0,1,2,3,4,5,6,7,8,9 = 10
probability the pin consist of only 1 number
[tex]= \frac{1}{10} + \frac{1}{9} + \frac{1}{8} \\\\[/tex]

Simplify the expression. -2.5f + 0.4f - 14 - 3?
Answer:
-2.1f-17
Step-by-step explanation:
combine like terms
Answer:
-2.1f-17
Step-by-step explanation:
1. Combine like terms
Like terms are those that either have the same variable, degree, or no variable at all.
Here, -2.5f and 0.4f and -14 and -3 are like terms. -2.5f and 0.4f are like terms because they both have f beside them. The reason -14 and -3 are like terms is because they both stand alone with no variables.
Combining like terms means to either add or subtract them from each other depending on their signs.
Just think of them as two separate problems for now.
-2.5f + 0.4f = ?
add these two together to get -2.1f
-14-3
Subtract these to get -17.
2. Put the expression back together: -2.1f-17

The circumference of a circular tablecloth is 160 inches, Will the tablecloth cover
a table with diameter 52 inches?
Answer:
D= 50.92 in
Step-by-step explanation:
Step one:
Given data
The circumference of a circular tablecloth is 160 inches
We want to know if the circular table cloth can also cover a table of diameter 52 in
Step two:
let us solve for the diameter of the table cloth given that the circumference is
160in
circumference
[tex]C= 2 \pi r[/tex]
[tex]160= 2*3.142*r\\\\160= 6.284r[/tex]
divide both sides by 6.284
[tex]160/6.284= r\\\\r=25.46 in[/tex]
The diameter of the table cloth is
[tex]=25.46*2\\\\=50.92 in[/tex]
The Table cloth cannot cover the table because the diameter of the cloth is not up to the diameter of the table

A certain map shows two roads. Road A is 1 1/5 miles long but it is 1 4/5 long on the map. What is the unit rate for inches per mile? If road B is 4 miles long, how long is road B on the map?
Answer: 6 inches
Step-by-step explanation:
Road in inches = 1 ⁴/₅
Road in miles = 1 ¹/₅
Inches per mile = 1 ⁴/₅ / 1 ¹/₅
= 1.5 inches
If the road is 4 miles long, on the map it would be;
= 1.5 * 4
= 6 inches

Answer:
Option 4 (4, 2, 3)
Step-by-step explanation:
Coordinances for a three-dimensional coordinate system are (x, y, z).
The letter labeling each axis is always on the positive side.
Therefore, all of the coordinances must be positive.
If you look at the x,y plane you can identify that the point is two over on the y axis and four over on the x. You can use this same strategy on the z axis to get the coordinances (4, 2, 3).
A thermometer shows a temperature of Negative 20 and three-fourths degrees. A chemist recorded this temperature in her notebook using a decimal. Which number did the chemist write in the notebook?
Negative 21.ModifyingAbove 4 with bar
Negative 21.ModifyingAbove 3 with bar
Negative 20.75
Negative 20.34
Answer: Negative 20.75
Step-by-step explanation:
The question simply wants us to convert the temperature shown by the thermometer to decimal. We should note that the temperature shown is Negative 20 and three-fourths degrees.
First, we convert 3/4 to decimal. This will be:
= 3/4 = 0.75.
Therefore, -20 3/4 = -20.75

In ΔWXY, the measure of ∠Y=90°, XW = 89, WY = 80, and YX = 39. What ratio represents the cosine of ∠X?
Answer:
It's 39/89
Step-by-step explanation:
cos X = adjacent/ hypotenuse = 39/89
[tex]\frac{39}{89}[/tex] represents cosine of ∠X.
What is cosine?
'In a right-triangle, cos is defined as the ratio of the length of the adjacent side to that of the longest side which is the hypotenuse.'
According to the given problem,
In the right angle triangle ΔWXY,
Hypotenuse = XW = 89
Perpendicular = WY = 80
Base = YX = 39
We know,
cos∅ = [tex]\frac{Base}{Hypotenuse}[/tex]
⇒ cosX = [tex]\frac{39}{89}[/tex]
Hence, we can conclude that the ratio [tex]\frac{39}{89}[/tex] represents the cosine of ∠X

Given parallelogram ABCD with mZBAD = 83° and m2 CBA = (9x + 7), 1 point
find the value of x.
Answer:
x is 10
Step-by-step explanation:
For a parallelogram, the sum of adjacent angles equals 180 degrees. Based on the given shape, mZBAD and <CBA are adjacent to each other
Hence mZBAD + mZCBA = 180
83 + 9x + 7 = 180
90 + 9x = 180
9x = 180-90
9x = 90
x = 90/9
x = 10
Hence the value of x is 10

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Hudson and 7 of his friends found a bag of pennies.
Total pennies= 320
So, Pennie get by each
=320 ÷ 8
= 40
