Answer:

The  value is  [tex]p-value = 0.0297[/tex]

Step-by-step explanation:

From the question we are told that

   The population mean is  [tex]\mu = 420 \ g[/tex]

   The The  sample  size is [tex]n = 49[/tex]

    The sample  mean is  [tex]\= x = 413 \ g[/tex]

    The  population variance is   [tex]\sigma^2 = 676[/tex]

Generally the population standard deviation is  mathematically represented as

     [tex]\sigma = \sqrt{\sigma^2 }[/tex]

     [tex]\sigma = \sqrt{676}[/tex]

     [tex]\sigma = 26[/tex]

The null hypothesis is  [tex]H_o : \mu = 420 \ g[/tex]

The  alternative  hypothesis is [tex]H_a : \mu < 420 \ g[/tex]

 Generally the test statistics is mathematically represented as

          [tex]z = \frac{ \= x - \mu }{ \frac{ \sigma }{\sqrt{n} } }[/tex]

=>        [tex]z= \frac{ 413 - 420 }{ \frac{ 26 }{\sqrt{49} } }[/tex]

=>       [tex]z = -1.884[/tex]

The  p-value is  obtained from the z-table table and the value is  

       [tex]p-value = P(Z < -1.885) = 0.029715[/tex]

       [tex]p-value = 0.0297[/tex]

Answer:

23 units

Step-by-step explanation:

Use the distance formula: d = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]

Plug in the 2 points:

d = [tex]\sqrt{(-12 - 11)^2 + (-4 + 4)^2}[/tex]

d = [tex]\sqrt{529}[/tex]

d = 23

So, the distance is 23 units

Answer:

length of the line segment =23

Step-by-step explanation:

[tex] (11, −4) = (x_1 , y_1) \\ (−12, −4) = (x_2 , y_2) \\ d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} }[/tex]

Plug in the values into the equation

[tex]d = \sqrt{( - 12 - 11)^{2} + ( - 4 - ( - 4)^{2} } [/tex]

Simply :

-12-11=- -23

-4(-4) = -4+4=0

[tex]d = \sqrt{( - 23)^{2} + {(0)}^{2} } \\ d = \sqrt{529 + 0} \\ d = \sqrt{529} \\ d = 23[/tex]

Answer:

[tex](a)[/tex]  [tex]dy = 5sec^2(5t) \ dt[/tex]

[tex](a) \ dy = \frac{-20v}{(5+v^2)^2} \ dt[/tex]

Step-by-step explanation:

Given;

(a) y = tan(5t)

[tex](b) \ y = \frac{5-v^2}{5+v^2}[/tex]

Solving for (a)

y = tan(5t)

let u = 5t          

⇒y = tan(u)

du/dt = 5

dy/du = sec²u

[tex]\frac{dy}{dt} =\frac{dy}{du} *\frac{du}{dt} \\\\\frac{dy}{dt} = sec^2(u)*5\\\\\frac{dy}{dt} = 5sec^2(u)\\\\\frac{dy}{dt} = 5sec^2(5t)[/tex]

[tex]dy = 5sec^2(5t) \ dt[/tex]

Solving for b;

let u = 5 - v²

du/dv = -2v

let v = 5+ v²

dv/du = 2v

[tex]\frac{dy}{dv} = \frac{vdu - udv}{v^2} \\\\\frac{dy}{dv} = \frac{-2v(5+v^2) - 2v(5-v^2)}{(5+v^2)^2}\\\\\frac{dy}{dv} = \frac{-10v-2v^3-10v+2v^3}{(5+v^2)^2}\\\\[/tex]

[tex]\frac{dy}{dv} = \frac{-10v-10v}{(5+v^2)^2}\\\\\frac{dy}{dv} = \frac{-20v}{(5+v^2)^2}\\\\dy = \frac{-20v}{(5+v^2)^2} dt[/tex]

9 = 11

This is never true, so there are no solutions

Answer:

0.15 ( E )

Step-by-step explanation:

Assuming

video game to be : V

electronics : E

clothing : C

From the content of the question

V = 2c

hence E = 2/3 V - 1/5 C  

              = 2/3 ( 2c ) -  1/5 c

              = [tex]\frac{17c}{15}[/tex]

therefore : V = 2c  and E =  17c / 15

assuming the number of clothing ( c ) = 15

V = 2*15 = 30  and E = ( 17 *15 ) / 15 = 17

Total number of items sold =  V + C + E = 30 + 15 + 17 = 62

from here we can determine the probability that of the five items independently sold that there are 3 video game, 1 electronic item and 1 clothing item

attached below is the remaining part of the solution

Answer:

Step-by-step explanation:

Answer: balance is -44 dollars

This indicates he owes 44 dollars

=======================================================

Explanation:

21 + (-30) = -9 is the balance if we don't account for the overdraft fee

If we do account for the overdraft fee, then -9 + (-35) = -44 is the bank balance.

Note how I'm using negative values to indicate balances in which Nick owes money, rather than it's the amount of money he has. So he owes the bank $44.

------------

A slightly different way to get the answer is to say

21-30 = -9

-9-35 = -44

This is because adding a negative is the same as subtraction.

Answer:

[tex]perimeter=90[/tex]

Step-by-step explanation:

We know that the length is four times the width, so:

[tex]l=4w[/tex]

We also know the area, which is 324 m². The formula for area:

[tex]A=l*w[/tex]

Insert the known values:

[tex]324=(4w)*w[/tex]

Solve for w. Simplify by removing parentheses:

[tex]324=4w*w\\324=4w^2[/tex]

Divide 4 from both sides to isolate the variable:

[tex]\frac{324}{4}=\frac{4w^2}{4} \\\\81=w^2[/tex]

Find the square root of both sides:

[tex]\sqrt{81} =\sqrt{w^2} \\\\w=9[/tex]

The width is 9 m.

We know the width. Now find the length by using the area formula and inserting known values:

[tex]324=l*9[/tex]

Solve for l. Divide both sides by 9:

[tex]\frac{324}{9}=\frac{l*9}{9}\\\\ l=36[/tex]

The length of the rectangle is 36. (You can check: 4 times 9 is 36)

Now find the perimeter:

[tex]P=2l+2w[/tex]

Insert values:

[tex]P=2(36)+2(9)\\\\P=72+18\\\\P=90[/tex]

The perimeter is 90 m.

Answer:

5

Step-by-step explanation:

The median is the middle number of the list when put in order from smallest to largest

3 3 4 5 5 5 6 6 6 7 8​

There are 11 numbers so the middle number is the  6th  ( 5 on the left and 5 on the right

3 3 4 5 5     5       6 6 6 7 8​

Answer: r=√6 or r≈2.45.

Step-by-step explanation:

To find the radius, you first need to know the equation of a circle.

Equation of a circle: [tex](x-h)^2+(y-k)^2=r^2[/tex]

Now that we know the equation of the circle, we can use it to find the radius of the given equation.

3.5(x+2.2)²+3.5(y-11.1)²-21=0

So far the equation looks pretty similar with the exception of the bolded areas. To get rid of them, we need to use our algebraic properties.

3.5(x+2.2)²+3.5(y-11.1)²-21=0                    [add both sides by 21]

3.5(x+2.2)²+3.5(y-11.1)²=21                       [factor out 3.5]

3.5((x+2.2)²+(y-11.1)²)=21                           [divide both sides by 3.5]

(x+2.2)²+(y-11.1)²=6

Now, our equation is the same as the one posted above. You may think that 6 is our radius, but if you look closely, the equation is equal to r². Therefore, 6 is actually r², not r.

r²=6                                                             [square root both sides]

r=√6

Finally, we have the final answer, r=√6 or r≈2.45.

Answer:

Number of dollars bills that can be fitted in Olympic pool = 1.67 billion.

Step-by-step explanation:

The dimensions of a dollar bill are 15.5956 cm by 6.6294 cm by 0.010922 cm. The U.S. federal government spent $3.8 trillion in fiscal year 2011.

An Olympic swimming pool is 50 m long, 25 m wide, and 1.5 m deep. How many Olympic pools would be filled by the dollar bills spent by the U.S. federal government in 2011

From above,

The volume for the dimension of the dollar bill = 15.5956 cm × 6.6294 cm × 0.010922 cm

The volume for the dimension of the dollar bill = 1.12922 cm³

The volume for the dimension of the dollar bill = 1.12922 × 10⁻⁶ m³

The volume of the pool = 50 m  ×  25 m  ×  1.5 m

The volume of the pool = 1875 m³

Number of dollars bills that can be fitted in pool = volume of the pool/volume of the dimension of dollar bills

Number of dollars bills that can be fitted in Olympic pool =1875 m³ / 1.12922 × 10⁻⁶ m³

Number of dollars bills that can be fitted in Olympic pool = 1,660,438,180

Number of dollars bills that can be fitted in Olympic pool = 1.67 billion.

 [tex]a_{3}[/tex] = 3

for n = 4

[tex]a_{4}[/tex] = 8

for n = 5

[tex]a_{5}[/tex] = 19

Step-by-step explanation:

A) A recurrence relation for the number of bit strings of length n that contain a  pair of consecutive Os can be represented below

if a string (n ) ends with 00 for n-2 positions there are a pair of  consecutive Os therefore there will be : [tex]2^{n-2}[/tex] strings

therefore for n ≥ 2

The recurrence relation for the number of bit strings of length 'n' that contains consecutive Os

[tex]a_{n} = a_{n-1} + a_{n-2} + 2^{n-2}[/tex]

b ) The initial conditions

The initial conditions are : [tex]a_{0} = a_{1} = 0[/tex]

C) The number of bit strings of length seven containing two consecutive 0s

here we apply the re occurrence relation and the initial conditions

[tex]a_{n} = a_{n-1} + a_{n-2} + 2^{n-2}[/tex]

for n = 2

  [tex]a_{2}[/tex] = 1

for n = 3

 [tex]a_{3}[/tex] = 3

for n = 4

[tex]a_{4}[/tex] = 8

for n = 5

[tex]a_{5}[/tex] = 19

Answer:

The range of numbers that Nidhi might be thinking of is between 3 and 9.

Step-by-step explanation:

We are given that Nidhi is thinking of a number n, and she wants her sister to guess the number.

Her first clue is that eight less than three times her number is between one and nineteen.

Let the number Nidhi is thinking be 'n'.

So, eight less than three times her number means that;

[tex](3\times \text{n}) - 8 = 3\text{n}-8[/tex]

Now, according to the question; the above equation is between one and nineteen, so;

[tex]1< 3\text{n}-8 < 19[/tex]

Adding 8 to the whole expression;

[tex]1+8< 3\text{n}-8 +8< 19+8[/tex]

[tex]9< 3\text{n}< 27[/tex]

Dividing the whole expression by 3;

[tex]\frac{9}{3} < \frac{3\text{n}}{3} < \frac{27}{3}[/tex]

[tex]3< \text{n}< 9[/tex]

Hence, the range of numbers that Nidhi might be thinking of is between 3 and 9.
