how many combinations of 3 letters can be made from the word oranges ? what is the probability that these three letters will all be consonants?
The number of all possible combinations of 3 letters can be made from the word 'oranges' = 35
The probability that the three letters will be consonants = 0.114
In this question, we have been given a word 'oranges'
We need to find the number of ways in which the letters of orange can be arranged.
Also, we need to find the probability that these three letters will all be consonants.
The number of letters in the word oranges = 7
So, n = 7
We need combinations of 3 letters.
so, r = 3
The number of all possible combinations of 3 letters would be,
^7C_3 = 7! / (7 - 3)! (3!)
^7C_3 = 35
The number of combinations of 3 letters = 35
We can observe that the consonants in the word 'oranges' are:
r, n, g, s
The number of consonants = 4
The combinations of 3 consonants would be,
^4C_3 = 4! / (4 - 3)! 3!
^4C_3 = 4
The required probability would be,
p = ^4C_3 / ^7C_3
p = 4 / 35
p = 0.114
Therefore, the number of all possible combinations of 3 letters can be made from the word 'oranges' = 35
the probability that the three letters will be consonants = 0.114

A spherical ball has a diameter of 8 inches. The ball has a slow leak in which the air escapes at the rate of 2.5 inches per second. How long would it take for the ball to deflate? Round to the nearest tenth.
Answer:
107.2 seconds
Step-by-step explanation:
Step one:
given
the diameter of ball 8 inches
radius= 8/2 = 4 in
The volume of the ball
[tex]v=4/3 \pi r^3[/tex]
[tex]v= 4/3*3.142*4^3\\\\v= 4/3*3.142*64\\\\v= 804.35/3\\\\v=268.12 in^3[/tex]
Step two:
we know that
rate= quantity/time
rate= 2.4 in per second
quantity= 268.12
time=?
time= quantity/rate
time= 268.12/2.5
time= 107.2 seconds

IQR= (16)−(10)=6
Thus, option 'C' is true.
Step-by-step explanation:
Given the data
8, 9, 9, 10, 12, 12, 13, 14, 15, 15, 15, 16, 18, 19, 20
The interquartile range is equal to the difference between the 75th and the 25th percentiles
The 25th percentile is 10
The 75th percentile is 16
Finally,
IQR= (16)−(10)=6
Thus, option 'C' is true.
420 presents in 15 hours at this rate how many presents does Santa deliver in 5 hours
Answer:
140 Presenrs
Step-by-step explanation:
If Santa delivers 420 presents in 15 hours and to get to 5 hours you need to divide 15 to 3, so what you do to one number you must do to the other, so therefore divide 420 by 3 to get 140 presents in 5 hours.
Vaughn paints his porch floor and also the porch floors of 9 neighbors. Each floor is a rectangle that is 8.2 feet long and 6.7 feet wide. What is the exact total area of all the porch floors that Vaughn paints? Enter your answer in the box.
(My little sister needs help but I can't help her right now)
Answer:
494.46 feet²
Step-by-step explanation:
So the area of one porch floor is
=l×w
=8.2×6.7 feet²
=54.94 feet²
So he paints 9 porch floors
So the exact total area of all the porch floors that Vaughn paints is
=54.94×9 feet²
=494.46 feet²

Which statement best illustrates using the vertical line test to determine if the graph below is a function of x?
A. The graph is not a function of x because the line x = 0 intersects the graph at two points.
B. The graph is a function of x because the line x = 5 does not intersect the graph.
C. The graph is not a function of x because the line y = 0 intersects the graph at two points.
D. The graph is a function of x because the line y = 5 does not intersect the graph.
Answer:
A
Step-by-step explanation:
Graph is not a function, so B and D are false.
y = 0 is a horizontal line, not a vertical line, so C is false.
This leaves only A.
10:Mohan lent altogether 6,600 to Ram and Shyam for 2 years. Ram agreed to
pay simple interest at 15 % p.a. and Shyam agreed to pay compound interest
at the same rate. If Ram paid Rs 112.50 more than Shyam as the interest, find
how much did he lend to each of them?
Answer:
Mohan lent 3600 to Ram and 3000 to Shyam.
Step-by-step explanation:
Given that Mohan lent altogether 6,600 to Ram and Shyam for 2 years.
Let Mohan lent x to Ram and y to Shyam
x+y=6600
Or, x=6600-y ...(i)
As Ram pays simple interest at 15 %=0.15 p.a, so, the interest paid by Ram in 2 years:
[tex]I=x\times 0.15 \times 2 \\\\\Rightarrow I=0.3x \\\\[/tex]
[tex]\Rightarrow I=0.3(6600-y) \\\\[/tex] [by using (i)]
[tex]\Rightarrow I=1980-0.3y \cdots(ii)[/tex]
As Shyam pays compound interest at 15 %=0.15 p.a,
so, the interest paid by Shyam in 2 years, C.I.= Final amount - Initial principal amount
[tex]C.I. = y(1+0.15)^2-y \\\\\Rightarrow C.I. = y(1.15^2-1) \\\\\Rightarrow C.I. = y(1.3225-1) \\\\\Rightarrow C.I. = 0.3225y \cdots(iii)[/tex]
As Ram paid Rs 112.50 more than Shyam as the interest, so by using equations (ii) and (iii),
[tex](1980-0.3y)-0.3225y=112.5 \\\\\Rightarrow 1980-0.3y-0.3225y=112.5 \\\\\Rightarrow 0.6225y=1980-112.5 \\\\\Rightarrow y = 1867.5/0.6225=3000[/tex]
From equations (i),
[tex]x=6600-3000=3600[/tex]
Hence, Mohan lent 3600 to Ram and 3000 to Shyam.
Given the equation 12x – 6y = –36, identify the slope and y-intercept.

find the value of 7w+9 given that -4w -4=4
can someone please help!! it would mean the world to me:) i fave finals tomorrow
Answer:
w= -1/3
Let's solve your equation step-by-step.
7w+9−4w−4=4
Step 1: Simplify both sides of the equation.
7w+9−4w−4=4
7w+9+−4w+−4=4
(7w+−4w)+(9+−4)=4(Combine Like Terms)
3w+5=4
3w+5=4
Step 2: Subtract 5 from both sides.
3w+5−5=4−5
3w=−1
Step 3: Divide both sides by 3.
3w/3=−1/3
w= −1/3
Answer:
w= −1/3
