Complete Question
The complete question is shown on the first uploaded image
Answer:
a
[tex]P(X < 4) = 0.4141 [/tex]
b
[tex]P(4 < X < 6) = 0.32876[/tex]
c
[tex]P(X >8) = 0.064037 [/tex]
d
The correct option is B
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 4.5[/tex]
The standard deviation is [tex]\sigma = 2.3[/tex]
Generally the probability that a randomly selected study participant's response was less than 4 is mathematically represented as
[tex]P(X < 4) = P(\frac{X - \mu }{\sigma} < \frac{4 - 4.5}{ 2.3} )[/tex]
[tex]\frac{X -\mu}{\sigma} = Z (The \ standardized \ value \ of\ X )[/tex]
So
[tex]P(X < 4) = P(Z < -0.217 )[/tex]
From the z-table [tex]P(Z < -0.217 ) = 0.4141[/tex]
So
[tex]P(X < 4) = 0.4141 [/tex]
Generally the probability that a randomly selected study participant's response was between 4 and 6 is mathematically represented as
[tex]P(4 < X < 6) = P( < \frac{4 - 4.5}{ 2.3} < \frac{X - \mu }{\sigma} < \frac{6 - 4.5}{2.3})[/tex]
=> [tex]P(4 < X < 6) = P( \frac{4 - 4.5}{ 2.3} < \frac{X - \mu }{\sigma} < \frac{6 - 4.5}{2.3})[/tex]
=> [tex]P(4 < X < 6) = P( -0.217 < Z< 0.6522[/tex]
=> [tex]P(4 < X < 6) = (Z< 0.6522) -P( Z < -0.217) [/tex]
From the z-table
[tex](Z< 0.6522) = 0.74286 [/tex]
So
[tex]P(4 < X < 6) = 0.74286 -0.4141[/tex]
=> [tex]P(4 < X < 6) = 0.74286 -0.4141[/tex]
=> [tex]P(4 < X < 6) = 0.32876[/tex]
Generally the probability that a randomly selected study participant's response was more than 8 is mathematically represented as
[tex]P(X > 8) = P(\frac{X - \mu }{\sigma} > \frac{8 - 4.5}{ 2.3} )[/tex]
[tex]P(X > 8) = P(Z > 1.52174 )[/tex]
From the z-table [tex]P(Z > 1.52174 ) = 0.064037[/tex]
So
[tex]P(X >8) = 0.064037 [/tex]

Solving (a): Mean
[tex]Mean = np[/tex]
[tex]Mean = 5 * 0.87[/tex]
[tex]Mean = 4.35[/tex]
Solving (b): Standard Deviation (SD)
[tex]SD = np(1 - p)[/tex]
[tex]SD = 5 * 0.87(1 - 0.87)[/tex]

how do u write 2.25 in standard form?
Answers
9514 1404 393
Answer:
2.25
Step-by-step explanation:
The number 2.25 is already in standard form.
___
In the US (and other places), "standard form" is an ordinary decimal number, with the integer part to the left of the decimal point and the fractional part to the right of the decimal point: 2.25.
In the UK (and other places), "standard form" is a number written in scientific notation with a mantissa consisting of the leading non-zero digit to the left of the decimal point, the remaining significant digits to the right of the decimal point, and a multiplier that is 10 to the power appropriate to the place value of the leading digit. When the multiplier is 1, we need not write it.
2.25 = 2.25×10⁰ (full form) = 2.25 (with superfluous 10⁰ removed)
1.6.PS-21 Question Help Challenge A gold mine has two elevators, one for equipment and another for the miners. The equipment elevator descends 5 feet per second. The elevator for the miners descends 17 feet per second. One day, the equipment elevator begins to descend. After 29 seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 16 seconds? At that time, which elevator is deeper? The position of the equipment elevator relative to the surface is feet
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Equipment elevator :
Descent rate = 5 ft/s
Miner's elevator :
Descent rate = 17 ft/s
Position of elevator after 16 seconds
Total descent time of equipment elevator = (29 + 16) = 45 seconds
Position after 45 Seconds :
Descent rate * time
5ft/s * 45s = 225 ft
Descent time of Miner's elevator = 16 seconds
Position after 16 Seconds :
Descent rate * time
17ft/s * 16s = 272 fts
Miner's elevator is deeper = 272 feets > 225 fts
Position of equipment elevator relative to the surface = - 225fts

A supply of foods last for a week for 20 families. how long would the supply last for 3 more families.?
Answers
Given that,
A supply of foods last for a week for 20 families.
It is required to find the time that would the supply last for 3 more families.
20 families = 1 week = 7 days
If 3 more families joined, total no of families are now 23.
It means that,
1 family= (20/7) days
Now,
23 family =
[tex]\dfrac{20}{7}\times 23=65.71\ \text{days}\\\\\approx 66\ \text{days}[/tex]
So, the supply will last for 66 days.
Cindy’s square garden has a side length of x ft. She will plant 5 tulip bulbs per square foot. Write a function g to model the number of bulbs she will plant. Use your function to determine how many bulbs will she plant if the garden has a side length of 8 feet?
Answers
Answer:
The function that model the number of bulbs she will plant is g = 5x²
She will plant 320 bulbs in the garden
Step-by-step explanation:
∵ Cindy’s square garden has a side length of x ft
∵ Area of the square = side × side
∴ The area of the garden = x × x
∴ The area of the garden = x² ft²
∵ She will plant 5 tulip bulbs per square foot
→ That means there are 5 tulip bulbs in 1 foot²
∵ The area of the garden is x² ft²
→ Multiply the area of the garden by 5
∴ The number of tulip bulbs in the garden = 5 × x²
∴ The number of tulip bulbs in the garden = 5x²
∵ g represents the number of bulbs she will plant in her garden
∴ g = 5x²
∴ The function that model the number of bulbs she will plant is g = 5x²
∵ The garden has a side length of 8 feet
→ That means the value of x is 8 feet
∴ x = 8
→ Substitute the value of x in the function above
∴ g = 5(8)² = 5(64)
∴ g = 320
∴ She will plant 320 bulbs in the garden

Use trigonometric identities to transform the left side of the equation into the right side (0 < θ < π/2). Fill in the blank tan θ cot θ = 1 tan θ cot θ = sin θ/cos θ * blank/sin θ = 1
Answers
Answer:
Cosθ
Step-by-step explanation:
Given the trigonometry identity:
tan θ cot θ = 1, to transform this identity, we need to write in terms of sinθ and cosθ as shown;
In trig:
tanθ = sinθ/cosθ
cotθ = 1/tanθ
1/tanθ = 1/(sinθ/cosθ)
1/tanθ = cosθ/sinθ
Hence cotθ = cosθ/sinθ
Substitute the expression for tanθ and cotθ into the expression in question
tan θ cot θ = 1
sinθ/cosθ*cosθ/sinθ = 1
Comparing the gotten expression with
sin θ/cos θ * blank/sin θ = 1 we can dee that the blank is cosθ
Hence the correct answer is cosθ
The identity which should be filled into the blank is cos θ.
Trigonometric identities;From trigonometric identities; we know;
tan θ = sin θ/cos θ cot θ = cos θ/sin θ .Ultimately, sin θ/cos θ × cos θ/sin θ = 1.
Therefore, the missing identity is cos θ.

The age of A is 4 years more than that of B. Four years ago, the ratio of their ages was 3: 2. Find their present ages.
Answers
Answer:
Present age of A = 16 years
Present age of B = 12 years
Step-by-step explanation:
Let the age of B be x years.
Therefore, age of A = (x + 4) years
Four years ago:
Age of A = (x + 4 - 4) = x years
Age of B = (x - 4) years
According to the given information:
[tex] \frac{x}{x - 4} = \frac{3}{2} \\ \\ 2x = 3(x - 4) \\ \\ 2x = 3x - 12 \\ \\ 2x - 3x = - 12 \\ \\ - x = - 12 \\ \\ x = 12 \\ \\ x + 4 = 12 + 4 = 16 \\ \\ present \: age \: of \: a = 16 \: yeras \\ \\ present \: age \: of \: b = 12 \: years \\ [/tex]
