The numerical values of the mean and standard deviation are 4 and 1.55, respectively
The numerical value of the probability that x = 6.The given parameters are:
n = 10
π = 0.4
The probability is then calculated as:
[tex]P(x) = ^nC_x * \pi^x *(1-\pi)^{n-x}[/tex]
So, we have:
[tex]P(6) = ^{10}C_6 * 0.4^6 *(1-0.4)^4[/tex]
Apply the combination formula
[tex]P(6) = \frac{10!}{6!4!} * 0.4^6 *0.6^4[/tex]
So, we have:
[tex]P(6) = 210 * 0.4^6 *0.6^4[/tex]
Evaluate
P(6) = 0.1115
Hence, the numerical value of the probability that x = 6 is 0.1115
The numerical values of the mean and standard deviationThe mean value is:
[tex]\bar x = n\pi[/tex]
This gives
[tex]\bar x = 10 * 0.4[/tex]
[tex]\bar x = 4[/tex]
The standard deviation value is:
[tex]\sigma = \sqrt{\bar x(1-\pi)[/tex]
This gives
[tex]\sigma = \sqrt{4(1-0.4)[/tex]
[tex]\sigma = 1.55[/tex]
Hence, the numerical values of the mean and standard deviation are 4 and 1.55, respectively

Beth’s brother is 140% of Beth’s height. If Beth’s brother measures 140cm, how tall is Beth?
Answer:
100 cm
Step-by-step explanation:
let x be the height of Beth
and y be the height of Beth's Brother
By 1st Condition
y = 140% * x
y = (140/100) * x
y = 1.4 x ..........................(Eq 1)
By 2nd Condition
y = 140
Put the value of y in the equation 1
140 = 1.4 *x
x = 140 / 1.4
x = 100 cm

Evaluate each expression using the value w=4, a=2, and h=5
Equation is:
6w+2a
Answer:
6w + 2a = 28
Step-by-step explanation:
the expression given, 6w + 2a, contains no variable h, so it's best to just ignore that h = 5.
first, plug in the values for w and a. you can do this in whatever order you want, but i'll start with w for this example.
plug in 4 for w.
6w + 2a
6(4) + 2a
now plug in 2 for a.
6(4) + 2a
6(4) + 2(2)
after plugging in the values, your expression is 6(4) + 2(2).
all that's left is to simplify. again, this can be done in whatever order you prefer, but i'm going to start with 6(4).
6(4) + 2(2)
24 + 2(2)
continue simplifying by multiplying 2(2).
24 + 2(2)
24 + 4
now add 24 + 4.
24 + 4 = 28
so, when w = 4 and a = 2, 6w + 2a = 28.
you can check the answer by plugging those values for a and w back into the completed equation.
6w + 2a = 28
6(4) + 2(2) = 28
24 + 4 = 28
28 = 28
since both sides of the equation are equal, that means that your answer of 28 is correct! :)

A rectangular swimming pool measures 40 ft by 60 ft and is surrounded by a path of uniform width around the four edges. The perimeter of the rectangle formed by the pool and the surrounding path is 248 ft. Determine the width of the path.
Answer:
6ft
Step-by-step explanation:
Lets x = the width of the path the surrounding path will add 2x to the pool dimension,therefore over all dimesion: (2x+40) by (2x+60) the overall perimeter (2x + 40) + 2(2x+60) = 248 Simplify divide by 2, result (2x+40) +(2x+60) = 124
Combine like terms 2x + 2x +40 +60 =124
4x + 100 = 124
4x=124 = 100
4x=24
x=24/4
x= 6ft is the width of the path
check this by finding the perimeter with these values; 2x = 12 ft
2 ( 12 + 40 ) + 2( 12 +60 )
2( 52 + 2(72)
104 + 144 = 248; confirms our solution of x= 6 ft

Suppose your friends have the following ice cream preferences: 31% of your friends like chocolate (C). The remaining do not like chocolate. 15% of your friends like sprinkles (S) topping. The remaining do not like sprinkles. 5% of your friends like Chocolate (C) and also like sprinkles (S). Of the friends who like sprinkles, what proportion of this group likes chocolate
Answer:
0.3333 = 33.33% of this group likes chocolate
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
Of the friends who like sprinkles, what proportion of this group likes chocolate:
So,
Event A: Likes sprinkles
Event B: Likes chocolate
15% of your friends like sprinkles (S) topping.
This means that [tex]P(A) = 0.15[/tex]
5% of your friends like Chocolate (C) and also like sprinkles (S).
This means that [tex]P(A \cap B) = 0.05[/tex]
So
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.05}{0.15} = 0.3333[/tex]
0.3333 = 33.33% of this group likes chocolate

Capon City has 5 more than 3 times as many residents as Harbor City.
Create an algebraic expression to represent the number of residents in Capon City. Use r in your expression where r represents the number of residents in Harbor City
Answer:
y=3r+5
Step-by-step explanation:
Break up the sentance.
Capon city has 5 more than 3 times as many residents as harbor city.
The sentance above can be written like this: y=5+3x. Since they want r to represent the number of people in Harbor city, use r in place of x.
Capon city=y
has=equal sign
5 more=+5
3 times as many=3r
y=3r+5
Pls help me with this question
Answer:
[tex]y = 2000(1.05)^{36[/tex]
Step-by-step explanation:
Given
[tex]a = 2000[/tex] -- Initial population
[tex]r = 5\%[/tex] --- Rate (monthly)
Required
Determine the population in 3 years
The question shows an exponential distribution and the final population will be calculated using:
[tex]y = a(1 + r)^x[/tex]
Where x is the number of months.
[tex]x = 3\ years[/tex]
[tex]x = 3* 12\ months[/tex]
[tex]x = 36[/tex]
So, we have:
[tex]y = 2000(1 + 5\%)^{36[/tex]
Convert % to decimal
[tex]y = 2000(1 + 0.05)^{36[/tex]
[tex]y = 2000(1.05)^{36[/tex]
