What is the mBC ?
mBC
Please help
Step-by-step explanation:
< AEB + < BEC = 180° {BEING LINEAR PAIR }
26° + < BEC = 180°
< BEC = 180° - 26°
< BEC = 154°
ARC BC = < BEC ( relation between arc and central angle)
Arc BC = 154°

code is formed using four of these letters: A, B, I. K, N, O, and T. (Note that the order of the letters in the code matters; for example, ABIK
different code from BAIK.
The size of the sample space is
. The probability that the first three letters of the four-letter code are vowels is
Answer:
The size of the sample is 840.
The probability that the first three letters of the four-letter code are vowels is=\frac{1}{35}=
35
1
Step-by-step explanation:
Th total number of letters given to form code of 4 letters = 7
Since, the order of the letters in the code matters, which means there is no repetition.
The total number of ways to form the code size =7*6*5*4=8407∗6∗5∗4=840
Therefore, The size of the sample is 840.
Since, there are 3 vowels and rest of 4 letters are consonant.
The number of ways to form code such that the first three letters of the four-letter code are vowels =3\times2\times1\times4=243×2×1×4=24
The probability that the first three letters of the four-letter code are vowels is
=\frac{24}{840}=\frac{1}{35}

Could you explain how you got the answer
Answer:
1) 3
2) 5/4
3) 5/9
Step-by-step explanation:
1) Change the sign to multiplication and change 1/4 into it's reciprocal which is 4/1. Multiply 3/4 · 4/1 to get 12/4.
Simplifies to 3
2) Change the sign to multiplication and find the reciprocal of 1/2 which is 2/1. Multiply 5/8 · 2/1 to get 10/8
Simplifies to 5/4
3) First, change the sign to multiplication then find the reciprocal of 3/4 which is 4/3. Multiply 5/12 · 4/3 to get 20/36.
Simplifies to 5/9

(THIS IS NOT A MULTIPLE CHOICE)
Answer:
a) clusters: none, gaps: 99, and 100, peaks: 101, outliers: none.
b) center of distribution:
median: 101, mean: 99.9090.
(a)
The outliers are the values that are far from the middle.
In this case, the outliers are 97, 98, 98, 98.
A cluster occurs when the data occurs within a small interval.
In this case, there's a cluster between 100 and 102.
According to the dot plot, there's a gap from 98 to 101.
At last, the peak is at 101, which is the value with the highest frequency.
(b)
The given data set doesn't form a normal distribution because there's no data in the middle of the data set, instead, there's a gap. Additionally, the spread or range of the data set is 5, where the majority of the data is not in the middle which mean the dispersion of the data is important.

if arc lm = 20 ft, find the radius of N
Answer:
120 ft
Step-by-step explanation:
60/360 or 1/6 of circle = 20 ft
full circle = 20 x 6 = 120 ft
diameter = 120/3.14 = 38.22 ft
radius = 38.22/2 = 19.11 ft
Answer:
Step-by-step explanation:
60° = ⅙ of 360°, so length of arc LM = ⅙ of 2πr.
20 = 2πr/6
r = 60/π ft
3x2^+2(x+4x) when x=2
Answer:
32
Step-by-step explanation:
Given the algebraic expression;
[tex] 3x^{2} + 2(x + 4x) = 0 [/tex]
When x = 2
It simply means that we would substitute the value of x into the equation.
[tex] 3*2^{2} + 2(2 + 4*2) [/tex]
[tex] 3*4 + 2(2 + 8) [/tex]
[tex] 12 + 2(10) [/tex]
[tex] 12 + 20 [/tex]
[tex] 12 + 20 = 32 [/tex]
What is the measure of angle R?
Enter your answer as a decimal in the box. Round only your final answer to the nearest hundredth.
mZR
=
Answer:
m<R = 22.62°
Step-by-step explanation:
Reference angle = R
Opposite = 5 cm
Hypotenuse = 13 cm
Apply the trigonometric function SOH:
Sin R = Opp/Hyp
[tex] Sin (R) = \frac{5}{13} [/tex]
[tex] R = sin^{-1}(\frac{5}{13}) [/tex]
R = 22.6198649°
m<R = 22.62° (nearest hundredth)

For an isosceles triangle, the area can be easily calculated if the height (i.e. the altitude) and the base are known. Multiplying the height with the base and dividing it by 2, results in the area of the isosceles triangle.
The expected value of a random variable X is 140 and the standard deviation is 14. The expected value of the random variable Y
Complete question :
The expected value of a random variable X is 140 and the standard deviation is 14. The standard deviation of the random variable Y=3X-10 is:
Answer:
42
Step-by-step explanation:
Standard deviation of Y = 3X - 10
The variance of Y
Var(Y) = Var(3X - 10)
Var(Y) = Var(3X) - Var(10)
10 is a constant :
Var(10) = 0
Hence,
Var(Y) = Var(3x)
SD(Y) = Var(Y) = Var(3X)
SD(Y) = SD(3X)
SD(Y) = 3SD(X)
SD(X) = 14
SD(Y) = 3 * 14
SD(Y) = 42
The number of cars in 25 families is shown in the table. Calculate the mean number of cars in a family.
No of cars Frequency
1 5
2 10
3 7
4 2
5 1
Answer:
Mean = 11.8
Step-by-step explanation:
Given the following data;
Total number of cars (n) = 5
Number of cars (x) = 1, 2, 3, 4, 5
Frequency (F) = 5, 10, 7, 2, 1
F(x) = (1*5) + (2*10) + (3*7) + (4*2) + (5*1)
F(x) = 5 + 20 + 21 + 8 + 5
F(x) = 59
To find the mean;
Mean = F(x)/n
Mean = 59/5
Mean = 11.8
