Let X= the number of words per minute on a typing test. Then, X∼N(42,5.5). Suppose Hugo types 60 words per minute in a typing test on Wednesday. The z-score when x=60 is ________. This z-score tells you that x=60 is ________ standard deviations to the ________ (right/left) of the mean, ________. Correctly fill in the blanks in the statement above.

Answers

Answer 1

The z score when x = 60 is 3.27.

This z score tells you that x = 60 is 3.27 standard deviations to the right of the mean.

Given,

Consider as a normal distribution:

The mean should be equals to 42 (μ)

The standard deviation (σ) = 5.5

We have to find the z score when x = 60.

That is,

z = (x - μ) / σ = (60 - 42) / 5.5 = 18/5.5 = 3.27

Therefore,

The z score when x = 60 is 3.27.

This z score tells you that x = 60 is 3.27 standard deviations to the right of the mean.

Hi, I am testing the service for Brainly. Can you help me find the median for this set of numbers: 3, 4, 15, 27, 53, 54, 68, 77?

Answers

To find the median of a set of numbers, the first step is:

1 - Put the numbers in crescent order

This set of numbers is already in crescent order, so we can skip this step

2 - Count how many numbers there are in the set.

In our set we have 8 numbers, so in this case, the median of the set will be the average value between the two central numbers (that is, the fourth and fifth numbers)

The fourth number is 27, and the fifth number is 53, so the median is the average of these two numbers:

[tex]\text{median = }\frac{(27\text{ + 53)}}{2}=\frac{80}{2}=40[/tex]

So the median of this set of numbers is 40.

Find the length of the rectangle pictured above, if the perimeter is 82 units.

Answers

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(length + width)

From the information given,

width = 16

Perimeter = 82

Thus, we have

82 = 2(length + 16)

By dividing both sides of the equation by 2, we have

82/2 = 2(length + 16)/2

2 cancels out on the right side of the equation. We have

41 = length + 16

length = 41 - 16

length = 25

If a random sample of 50 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by more than 3.3 millimeters? Round your answer to four decimal places.

Answers

The probability that the sample mean will differ from the population mean by more than 1.8 mm = 0.9949

Given,

In the question:

According to the given problem the mean diameter μ= 149 mm (population mean) and the standard deviation is σ = 8mm

random sample size, n= 50 steel bolts is selected

Let the random variable that represents the diameter of steel bolts be denoted by x and from the problem we have x = 3.3mm

Let z = (x-μ) / (σ/√n ) ....(1)

using formula (1) and when the sample mean differs from the population mean by more than 1.8mm

z = (3.3 - 149) /(8/√50 )

⇒z = -2.575

The probability that the sample mean will differ from the population mean by more than 1.8 mm

P( z > -2575) = 1 - P(z< -2.575) = 1 - 0.0051 = 0.9949

Hence, The probability that the sample mean will differ from the population mean by more than 1.8 mm = 0.9949.

c = Cost of one bag of chips

Equation

2.50 + 3c = 5.05

Solution

c = Cost of one bag of chips = 0.85 dollars

Explanation

Cost of one juice pouch = 1.25 dollars

Cost of 2 juice pouches = 2(1.25) = 2.50 dollars

Cost of a bag of chips = c dollars

Cost of 3 bags of chips = (3)(c) = (3c) dollars

(Cost of two juice pouches) + (Cost of three bags of chips) = Total Cost

2(1.25) + 3c = 5.05

2.50 + 3c = 5.05

Subtract 2.50 from both sides

2.50 + 3c - 2.50 = 5.05 - 2.50

3c = 2.55

Divide both sides by 3

(3c/3) = (2.55/3)

c = 0.85 dollars

The ages of three siblings, Ben, Bob and Billy, are consecutive integers. The square of the age of the youngest child Ben is four more than eight times the age of the oldest child, Billy. How old are the three boys?

Answers

Let the age of the youngest child (Ben) be x years.

Since the ages are consecutive integers, the ages of the other 2 are (x + 1) and (x + 2).

It was given that the age of the youngest child is four more than eight times the age of the oldest child. This means that:

[tex]x^2-4=8(x+2)[/tex]

We can rearrange the equation above and solve for x as a quadratic equation:

[tex]\begin{gathered} x^2-4=8x+16 \\ x^2-8x-20=0 \end{gathered}[/tex]

Using the factorization method, we have:

[tex]\begin{gathered} x^2-10x+2x-20=0 \\ x(x-10)+2(x-10)=0 \\ (x-10)(x+2)=0 \\ \therefore \\ x-10=0,x+2=0 \\ x=10,x=-2 \end{gathered}[/tex]

Since the age cannot be negative, the age of the youngest child is 10.

Therefore, the ages are:

[tex]\begin{gathered} Ben=10\text{ }years \\ Bob=11\text{ }years \\ Billy=12\text{ }years \end{gathered}[/tex]

Use the definition of the derivative to find the derivative of the function with respect to x. Show steps

Answers

Answer: [tex]\frac{5}{2\sqrt{5x+3\\} }[/tex]

Step-by-step explanation:

First, use the chain rule to quickly find the answer so that you can check after you go through the ridiculous process that is the bane of every calculus 1 student's existence.

f(x) = (5x + 3)^(1/2)

(d/dx) (5x + 3)^(1/2) =

(1/2)(5x + 3)^(-1/2) * (5) =

5/[2(5x+3)^(1/2)]

Now, we enter the first gate of hell:

f'(x) = the limit as h approaches 0 of [(f(x+h) - f(x))/h]

lim as h -> 0 of [(5(x+h)+3)^(1/2) - (5x+3)^(1/2)/h]

lim as h -> 0 of [(5x+5h+3)^(1/2) - (5x+3)^(1/2) / h]

Multiply numerator and denominator by the conjugate of the numerator, which is (5x+5h+3)^(1/2) + (5x+3)^(1/2).  

lim as h -> 0 of

[√(5x+5h+3) - √(5x+3) ] [√(5x+5h+3) + √(5x+3) ]

______________________________________

h[√(5x+5h+3) - √(5x+3) ]

Simplify the numerator via FOIL:

5x+5h+3 + √(5x+5h+3)√(5x+3) - √(5x+3)√(5x+5h+3) - (5x+3)

The remaining radicals in the numerator cancel each-other, giving us:

5x + 5h + 3 - 5x - 3

Simplify Further:

5h

Now that we have simplified our numerator, let's continue:

lim as h -> 0 of (5)(h)/[(h)((5x+5h+3)^(1/2) + (5x+3)^(1/2))]

The h in the numerator cancels the h in the denominator.

lim as h -> 0 of 5/[(5x+5h+3)^(1/2) + (5x+3)^(1/2)]

Now, we directly substitute h with 0 in the equation.

5/[ (5x+3)^1/2 + (5x+3)^(1/2) ]

In the denominator, both sides of the addition sign are the same, so we can simplify it further to:

5/[ 2(5x+3)^(1/2) ]

This is the same answer we received using the chain rule, so it is correct!

Answer:

Left circle:  6x + 2y

Bottom middle circle:  5x

Bottom right rectangle:  3x + y

Step-by-step explanation:

According to the question, the expression in each circle is the result of the sum of the two rectangles connected to it.

The expression in the left circle is the sum of the expressions in the rectangles above and below it:

⇒ (4x + 3y) + (2x - y)

⇒ 4x + 3y + 2x - y

⇒ 4x + 2x + 3y - y

⇒ 6x + 2y

Therefore, the expression in the left circle is 6x + 2y.

The expression in the right circle is the sum of the expressions in the rectangles above and below it, however the expression in the rectangle below this circle is missing.

To find the missing expression, subtract the expression in the rectangle above the circle from the expression in the circle:

⇒ (4x + 5y) - (x + 4y)

⇒ 4x + 5y - x - 4y

⇒ 4x - x + 5y - 4y

⇒ 3x + y

Therefore, the expression in the lower right rectangle is 3x + y.

The expression in the bottom middle circle is is the sum of the expressions in the rectangles to its left and right:

⇒ (2x - y) + (3x + y)

⇒ 2x - y + 3x + y

⇒ 2x + 3x - y + y

⇒ 5x

Therefore, the expression in the bottom middle circle is 5x.

The hands of a clock show 11:20. Express the obtuse angle formed by the hour and minute hands in radian measure.

Answers

ANSWER

[tex]2.44\text{ }rad[/tex]

EXPLANATION

First, let us make a sketch of the clock:

We have that for a minute hand:

[tex]1\text{ }min=6\degree[/tex]

For hour hand:

[tex]1\text{ }min=0.5\degree[/tex]

The hour and minute hand have their origin at 12.

At 11:20, the minute hand had moved 20 mins. This means that:

[tex]20\text{ }min=20*6=120\degree[/tex]

The hour hand had moved at 11 (and 20 mins more), which means:

[tex]\begin{gathered} 11*60\text{ }min+20\text{ }min \\ \Rightarrow660\text{ }min+20\text{ }min \\ 680\text{ }min \end{gathered}[/tex]

Hence, in 680 mins:

[tex]\begin{gathered} 680*0.5 \\ \Rightarrow340\degree \end{gathered}[/tex]

Therefore, the angle formed between 11 and 12 at 11:20 is:

[tex]\begin{gathered} 360-340 \\ \Rightarrow20\degree \end{gathered}[/tex]

Hence, the angle formed at 11:20 is:

[tex]\begin{gathered} 120\degree+20\degree \\ 140\degree \end{gathered}[/tex]

Now, let us convert to radians:

[tex]\begin{gathered} 1\degree=\frac{\pi}{180}rad \\ 140\degree=140*\frac{\pi}{180}=2.44\text{ }rad \end{gathered}[/tex]

That is the obtuse angle formed in radians.
