A fair con is tossed 80 times in an experiment. If the coin is fair, what would be a reasonable number of times tails should appear
based on your knowledge of the theoretical probability of this event?

Answers

Answer 1

Answer: 40 would be a reasonable number of times tails should appear if the coin is fair. Fair means 50/50 chance.

So, divide 80 by 2. 80/2 = 40.

Find the 11th term in the geometric sequence: 4, 6, 9,....

Answers

Answer:

69

Step-by-step explanation:

let the first term be n

second term = 2 + n

third term = 3 + second term so we can conclude that the other term will be:

forth term = 4 + third term

fifth term = 5 + forth term etc.

eleventh term will be 11 + 10 term

based on observations the tenth term is 58 so

eleventh term= 11 + 58

= 69

Draymond has $10.00 for lunch. He and his friend order pizza for $6,90 and two drinks for $1.50 each. Does he have enough money? Explain how you know below for full credit.

Answers

Answer:

yes. the total when added together is $9.90, meaning that he has just enough for them to get a pizza and one drink each.

Step-by-step explanation:

6.90

1.50

1.50

9.90

Answer:

Yes, he has enough money.

Step-by-step explanation:

He will have .10 left over. The pizza is $6.90 and the drinks are $1.50 each.

1.50 + 1.50 = 3.00

6.90 + 3.00 = 9.90

He spends $9.90, so he will be 10 cents short of spending all of his lunch money. Therefore, he has enough money.

f of x equals one half times x plus 16
f of x equals one half times x plus 19
f(x) = 2x + 16
f(x) = 2x + 19

Answers

Answer:

Part 1) Option A. f of x equals one half times x plus 16

Part 2) Option  A. x = 5

Part 3) Option C. x − 4y = −9

Part 4) Option A. The number of rides is the independent variable, and the total cost is the dependent variable.

Step-by-step explanation:

Part 1)

Let

x -----> the number of months

y ----> vertical jump in inches

step 1

Find the slope

we have the points

(0,16) and (2,17)

The equation of the line in slope intercept form is

we have

-----> the point (0,16) is the y-intercept

substitute

convert to function notation

f(x)=y

Part 2) What is the equation of a line that contains the points (5, 0) and (5, −2)?

step 1

Find the slope

we have the points

(5, 0) and (5, −2)

the slope is undefined

This is a vertical line (parallel to the y-axis)

therefore

The equation is

x=5

Part 3) Choose the equation that represents a line that passes through points (−1, 2) and (3, 1)

step 1

Find the slope

we have the points

(−1, 2) and (3, 1)

 

step 2

Find the equation of the line into point slope form

we have

substitute

Convert to standard form

Multiply by 4 both sides to remove the fraction

Part 4) Jewels has $6.75 to ride the ferry around Connecticut. It will cost her $0.45 every time she rides. Identify the dependent variable and independent variable in this scenario

we know that

The independent variable is the variable whose change isn’t affected by any other variable (An example the age and time)

The dependent variable it’s what changes as a result of the changes to the independent variable (An example of a dependent variable is how tall you are at different ages. The dependent variable (height) depends on the independent variable (age))

Let

x ----> the number of rides

y ----> the total cost in dollars

In this problem

The independent variable or input is the number of rides

The dependent variable or output is the total cost

-brainly user

Answer:

Your function would be y = 1/2x + 16.

Explanation:

Points: (0, 16); (2, 17)

Slope: m = (17 - 16) / (2 - 0) = 1/2

Slope intercept form: y = mx + b

So, if the slope equals 1/2 and the y-intercept is (0, 16), you would use substitution to get y = 1/2x + 16.

Therefore, your ending function is y = 1/2x + 16.

Answers

Answers:

25c= 1/2

Then R3.50 is 3/50

Step-by-step explanations:

25c as a fraction is 25/50, so you have to simplify 25/50 to its simplest form , and you get the result of 1/2

For this you have to first  find the GCD (or HCF) of numerator and denominator. GCD of 3 and 50 is 1.

3 ÷ 150 ÷ 1.

Reduced fraction: 350. Therefore, 3/50 simplified to lowest terms is 3/50.

Harriet had a remote control car every 4/15 of a second the remote control car travels 4/5 of a foot how many feet per second does the remote control car travel

Answers

Answer:

3 ft/s

Step-by-step explanation:

The rate or speed of the remote control car, v = distance/time

Now, the distance travelled by the remote control car = 4/5 of a foot = 4/5 × 1 ft = 4/5 ft and the time it takes to cover this distance is 4/15 of a second = 4/15 × 1 s = 4/15 s.

So, v = distance/time

= 4/5 ft ÷ 4/15 s

= 4/5 ft × 15/4 s

= 3 ft/s

Miguel compró 253 Kilos de pescado para venderlo en su negocio, si decide vender cada kilo de pescado en Bs 1.900.000. Entonces, ¿Cuánto dinero recaudó en total por la venta del pescado?

Answers

Answer:

Miguel recaudó Bs 480.700.000 por la venta del pescado.

Step-by-step explanation:

Con la información proporcionada puedes calcular el dinero que recaudó en total por la venta del pescado multiplicando el precio de venta de cada kilo de pescado por el número de kilos que Miguel compró:

Número de kilos comprados=253

Precio de venta por kilo=1.900.000

Total vendido=253*1.900.000

Total vendido=480.700.000

De acuerdo a esto, la respuesta es que Miguel recaudó Bs 480.700.000 por la venta del pescado.

ANSWER :

x⁰ = 360 degree- ( 246 + 66)

= 360 degree- 312

= 48

Answer:

x = 114

Step-by-step explanation:

Remark

You are trying to figure out what the arc is in degrees. The arc formula is

Intersect angle = 1/2( the furthest arc - the smaller closer arc).

Givens

Intersect angle = 66 degrees

Closer arc = x

Further or largest Arc = 246

Solution

66 = 1/2 (246 - x)                  Multiply both sides by 2 and remove the brackets.

132 = 246 - x                        Subtract 246 from both sides.

132 - 246 = - x

- 114 = - x                             Multiply both sides by -1

-1 (-114) = -1 * (-x)

x = 114

ANSWER IS 0.656

Answers

Answer:

Step-by-step explanation:

For each outcome there are

s!/(n!(s-n)!) combinations

where s is the number of selections and n is the number of specific outcomes

The probability of any specific outcome for 6 tosses of a coin is (1/2)^6

[(1/2)^6]*[(6!/6!)+(6!/(5!)+(6!/(4! 2!)+(6!/(3! 3!)]

(1/2)^6*(1+6+15+20)

42(1/2)^6

42(1/64)

42/64

21/32 which is 0.65625
