O $76.90

Answer:

A. $0.5

Step-by-step explanation:

In this question half of the time your winning is 2 dollars and also the other half of the time your loss is one dollar

The expectation is that after you must have had 2 rolls you would get 2 dollars once and also you are going to lose 1 dollar once. So what you won overall would be 1 dollar.

So the correct answer would be gotten from $1/2rolls

= $0.50

Answer:

The 3 digit numbers are;

171, 152, 133, 114, 285, 266, 247, 228, 209, 399

Step-by-step explanation:

Let the 3 digit number be xyz

Since x is the Hundreds digit, y is the tens digit and z is the unit digit, we have;

100x, 10y and z

We are told the sum of this is equal to 19 times the sum of their digits.

Thus;

100x + 10y + z = 19(x + y + z)

100x + 10y + z = 19x + 19y + 19z

This gives;

81x - 9y - 18z = 0

Divide through by 9 to get;

9x - y - 2z = 0

x = (2z + y)/9

Now, we will need to select values of z and y between 0 to 9 in such a way that (2z + y) is divisible by 9 and in such a way that x > 0 but ≤ 10

The possible solutions are;

At z = 1, y = 7 and x = 1

At z = 2, y = 5 and x = 1

At z = 3, y = 3 and x = 1

At z = 4, y = 1 and x = 1

At z = 5, y = 8 and x = 2

At z = 6, y = 6 and x = 2

At z = 7, y = 4 and x = 2

At z = 8, y = 2 and x = 2

At z = 9, y = 0 and x = 2

At z = 9, y = 9 and x = 3

Compiling all these, the 3 digit numbers are;

171, 152, 133, 114, 285, 266, 247, 228, 209, 399

Answer:

a) point estimate for the population proportion of all customers who experienced an interruption

E = 0.029

b)

90% confidence interval for the proportion of all customers who experienced an interruption

(0.11441 , 0.16319)

C)

Size of the sample 'n' = 509

Step-by-step explanation:

Step(i):-

a)

An Internet service provider sampled 540 customers and found that 75 of them experienced an interruption in high-speed service during the previous month.

Sample proportion

                           [tex]p = \frac{x}{n} = \frac{75}{540} = 0.1388[/tex]

The point estimate of all customers who experienced an interruption

                         [tex]E = \frac{Z_{\alpha }\sqrt{p(1-p)} }{\sqrt{n} }[/tex]

  Level of significance

                          Z₀.₀₅ = 1.96

                         [tex]E = \frac{1.96\sqrt{0.138(1-0.1388)} }{\sqrt{540} }[/tex]

                         E  =  0.029

b)

90% confidence interval for the proportion of all customers who experienced an interruption

[tex]( p - Z_{0.10} \sqrt{\frac{p(1-p)}{n} } ,p + Z_{0.10} \sqrt{\frac{p(1-p)}{n} })[/tex]

[tex]( 0.1388 -1.645 \sqrt{\frac{0.1388(1-0.1388)}{540} } ,0.1388 + 1.645 \sqrt{\frac{0.1388(1-0.1388)}{540} })[/tex]

( 0.1388 - 0.02439 , 0.1388 + 0.02439)

(0.11441 , 0.16319)

c)

Margin of error

                   [tex]M.E = \frac{Z_{0.05} \sqrt{p(1-p)} }{\sqrt{n} }[/tex]

                   [tex]0.03 = \frac{1.96 \sqrt{0.1388(1-0.1388)} }{\sqrt{n} }[/tex]

                   √n = 22.58

Squaring on both sides, we get

                 n = 509

Answer:

[tex]\huge\boxed{82 \textdegree}[/tex]

Step-by-step explanation:

We know that all angles in a triangle will add up to 180°. Since we know the measure of all 3 angles, we can create this equation:

[tex]31+x+(x-15) = 180[/tex]

Let's solve for x.

Combine like terms:

[tex]31+2x-15=180[/tex]

Add 15 to both sides:

[tex]31+2x=195[/tex]

Subtract 31 from both sides:

[tex]2x=164[/tex]

Divide both sides by 2:

[tex]x= 82[/tex]

So x is 82°.

Using the "fives fact" (5 x 6 = 30) as a starting point, we added one more group of 6 to reach the final result of 36.

To use the "fives fact" to solve 7 x 6, we can break it down into simpler calculations using the fact that 5 x 6 = 30.

Here's the step-by-step calculation:

1. Start with the "fives fact": 5 x 6 = 30.

2. Since we need to find 7 x 6, we can add another 6 to the result of 5 x 6:

  30 + 6 = 36

Therefore, 7 x 6 equals 36.

The height of the ball given by the polynomial describes the projectile

motion of the ball.

The polynomial that models the height of the ball Min throws, in feet is presented as follows;

Reasons:

The given polynomial for the height of the ball is; h(t) = -16·t² + v·t + h₀

Where;

v = The initial velocity of the ball

h₀ = The initial height

t = The time in seconds

The polynomial that models the height of the ball Min throws is given by substitution of the values of v, h₀, in the above equation as follows;

The height of the ball is; h(t) = -16·t² + 30·t + 6

Answer:

[tex]y = 250 + \frac{10x}{3}[/tex]

Step-by-step explanation:

Given

[tex]Daily\ Wages = 250[/tex]

[tex]Additional = 10[/tex] for every 3

Required

Determine the function that represents Jessie's daily earnings:

From the question, we have that:

y = earnings

x = phones

If for 3 phones, he gets 10.

i.e.:

3 pieces = 10

then

[tex]1\ pieces = \frac{10}{3}[/tex] ----- By dividing both sides by 3

and

[tex]x\ pieces = \frac{10x}{3}[/tex] ----- By multiplying both sides by x

The above expression represents the additional earnings for x phones

So, daily earnings y is calculated as :

[tex]y = Daily\ Wages + Additional\ Earnings[/tex]

[tex]y = 250 + \frac{10x}{3}[/tex]

The function representing his daily earning (y) as a function of the number  of cell phones sold (x) is y = (10/3)x + 250.

A linear equation is given  by:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept.

Let x represent the number of cell phones sold and y represent the daily earnings.

Since he has a daily wage of 250 pesos, hence b = 250. Also he makes additional  10 pesos for every 3 pieces of cell phone sold, hence m = 10/3.

The equation becomes:

y = (10/3)x + 250

Therefore the function representing his daily earning (y) as a function of the number  of cell phones sold (x) is y = (10/3)x + 250

Answer:

38/5

Step-by-step explanation:

15 x 3 = 45 + 3 = 48/15

then 4 + 5 = 20 + 2 = 22/5

22/5 + 48/15 = ?

find the common denominator  

15 ÷ by 3  so you do the same to the numerator so, 48 ÷ 3 = 16

then keep the 22 and 16 and put it as 16/5 and 22/5 and add them to get 38/5

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

Explanation:

The exponent rules are

The expression on the right hand side simplifies to c^(-1). We add the exponents to get this. So we're using rule 1 mentioned above.

We'll keep this in mind for later.

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

On the left hand side (c^5)^4 becomes c^(20) because we multiply the exponents (rule 3)

Then (c^20)/(c^x) becomes c^(20-x). We subtract exponents here (rule 2).

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

After using those exponent rules, the original equation turns into

c^(20-x) = c^(-1)

The bases are both c, so the exponents must be equal

20-x = -1

-x = -1-20

-x = -21

x = 21
