A linguistics expert is interested in learning about the amount of time people in his industry spend studying a new language. A random sample of 15 people in his industry were surveyed for a hypothesis test about the mean time people studied a new language last year. He conducts a one-mean hypothesis test, at the 10% significance level, to test the recent publication that the amount of time people in his industry are studying a new language was 30 minutes per week.

Step-by-step explanation:

[tex]\large\underline{\sf{Solution-}}[/tex]

Consider

[tex]\rm \: \cos \bigg( \dfrac{3\pi}{2} + x \bigg) \cos \: (2\pi + x) \bigg \{ \cot \bigg( \dfrac{3\pi}{2} - x \bigg) + cot(2\pi + x) \bigg \}cos(23π+x)cos(2π+x)[/tex]

We Know,

[tex]\rm \: \cos \bigg( \dfrac{3\pi}{2} + x \bigg) = sinx[/tex]

[tex]\rm \: {cos \: (2\pi + x) }[/tex]

[tex]\rm \: \cot \bigg( \dfrac{3\pi}{2} - x \bigg) \: = \: tanx[/tex]

[tex]\rm \: cot(2\pi + x) \: = \: cotx[/tex]

So, on substituting all these values, we get

[tex]\rm \: = \: sinx \: cosx \: (tanx \: + \: cotx)[/tex]

[tex]\rm \: = \: sinx \: cosx \: \bigg(\dfrac{sinx}{cosx} + \dfrac{cosx}{sinx} [/tex]

[tex]\rm \: = \: sinx \: cosx \: \bigg(\dfrac{ {sin}^{2}x + {cos}^{2}x}{cosx \: sinx}[/tex]

[tex]\rm \: = \: 1=1[/tex]

Hence,

[tex]\boxed{\tt{ \cos \bigg( \frac{3\pi}{2} + x \bigg) \cos \: (2\pi + x) \bigg \{ \cot \bigg( \frac{3\pi}{2} - x \bigg) + cot(2\pi + x) \bigg \} = 1}}[/tex]

how do I convert these probs? into base 10 4120_7, A3B_12, WXYZ_36

Answers

4120_7 = 4•7³ + 1•7² + 2•7¹ + 0•7⁰

4120_7 = 4•343 + 1•49 + 2•7 + 0•1

4120_7 = 1372 + 49 + 14

4120_7 = 1435

In base 12, we use the digits 0-9 as well as A for 10 and B for 11. So

A3B_12 = 10•12² + 3•12¹ + 11•12⁰

A3B_12 = 10•144 + 3•12 + 11•1

A3B_12 = 1440 + 36 + 11

A3B_12 = 1487

In base 36, we assign values between 10 and 35 to the letters A-Z, so that

WXYZ_36 = 32•36³ + 33•36² + 34•36¹ + 35•36⁰

WXYZ_36 = 32•46656 + 33•1296 + 34•36 + 35•1

WXYZ_36 = 1492992 + 42768 + 1224 + 35

WXYZ_36 = 1537019

b. 150 milliliters of the first brine solution, 850 milliliters of the second brine solution
Oc. 100 milliliters of the first brine solution, 900 milliliters of the second brine solution
O d. 200 milliliters of the first brine solution, 1,000 milliliters of the second brine solution
e. 900 milliliters of the first brine solution, 100 milliliters of the second brine solution

Answers

Using proportions, it is found that the correct option is:

c. 100 milliliters of the first brine solution, 900 milliliters of the second brine solution

The 1-liter solution, with 23.5% salt,  is composed by:

x liters of the first brine solution, with 10% salt.1 - x liters of the second brine solution, with 25% salt.

Hence, the combined equation is:

[tex]0.1x + 0.25(1 - x) = 0.235[/tex]

[tex]0.1x + 0.25 - 0.25x = 0.235[/tex]

[tex]0.15x = 0.015[/tex]

[tex]x = \frac{0.015}{0.15}[/tex]

[tex]x = 0.1[/tex]

Hence, 0.1L = 100 mL of the first solution, 900 mL of the second, and option c is correct.

A new drug Selttiks is proposed to treat sadness. Doctors are worried it also causes nausea. The proportion of 560 people who got sick while taking Selttiks was 13%. The proportion of 560 people who got sick while taking a placebo was 16.6%. Find a 89% confidence interval for the difference in the proportions that get sick with Selttiks vs the placebo.

Answers

Using the z-distribution and the information given, it is found that the 89% confidence interval for the difference in the proportions that get sick with Selttiks vs the placebo is (-0.07, -0.002).

The proportions, and it's respective standard errors, are given by:

[tex]p_s = 0.13, s_s = \sqrt{\frac{0.13(0.87)}{560}} = 0.0142[/tex]

[tex]p_p = 0.166, s_p = \sqrt{\frac{0.166(0.834)}{560}} = 0.0157[/tex]

The distribution of the difference has mean and standard error given by:

[tex]\pi = p_s - p_p = 0.13 - 0.166 = -0.036[/tex]

[tex]s = \sqrt{s_s^2 + s_p^2} = \sqrt{0.0142^2 + 0.0157^2} = 0.021[/tex]

The interval is:

[tex]\pi \pm zs[/tex]

The critical value using the z-distribution, for a 89% confidence interval, is z = 1.598, hence:

[tex]\pi - zs = -0.036 - 1.598(0.021) = -0.07[/tex]

[tex]\pi + zs = -0.036 + 1.598(0.021) = -0.002[/tex]

The 89% confidence interval for the difference in the proportions that get sick with Selttiks vs the placebo is (-0.07, -0.002).

Nik needs to estimate how many books will fit in a bin. Each book is 0.75 feet tall, 0.75 feet wide, and 0.25 feet thick. The bin is 4 feet wide, 4 feet tall, and 4 feet deep. Based on volume only, about how many books will fit in the bin?

Answers

Step-by-step explanation:

first you find the volume of a bin.

that is multiplication of 3 dimensions given.

4*4*4=64 cubic feet...

now volume of books..

0.75*0.75.0.25=0.14 cubic feet

now the number of books that will fit the bin=volume of bin/volume of books

64/0.14=455

455 books

We want to see how many books can fit in a bin, given that we know the dimensions of the books and the bin. We will see that 457 books can enter in the bin.

Remember that the volume of a rectangular prism of length L, width W, and height H is just given by:

V = L*W*H

Here we know that each book is:

0.75ft by 0.75ft by 0.25ft

Then the volume of a single book is:

V = 0.75ft*0.75ft*0.25ft = 0.14 ft^3)

While the bin is 4ft by 4ft by 4ft, thus its volume is:

V ' = 4ft*4ft*4ft = 64ft^3

The number of books that fit in the bin is given by the quotient between the bin's volume and the book's volume:

N = (64ft^3)/(0.14 ft^3) = 457 books.

An object is thrown upward from the top of a 192 ft building with an initial velocity of 64 feet
per second. The height, h, of the object after, t seconds, is given by the equation h =
- 16t2 + 640 + 192 When will the object hit the ground?

Answers

Answer:

t=6

Step-by-step explanation:

ground height = 0

(are you sure your formula is correct? isn't it - 16t²?)

if h=16t² +64t+192 is true then

16t² +64t+192 = 0

t² + 4t + 12 = 0

t = (-4 ± √(4² - 4*12)) / 2*1 = (-4 ± √-32) / 2 = -2 ± 2√-2

There is no solution of t

if it is h= - 16t² +64t+192

0 =- 16t² + 64t + 192

t² - 4t - 12 = 0

(t + 2) (t -6) = 0

t should be positive

t = 6 sec

2^7 is the same as 2 × 2 × 2 × 2 × 2 × 2 × 2 = 128

Then just multiply 128 and 16 to get 2,048, and see which option also gives you 2,048.

BUT, you can also:

(Combine the exponents together to get your answer. Just remember that if it's multiplication you add them, and if it's division you subtract them.)
