What is the probability of spinning an odd number and rolling and odd number?

ivolga24 [154]

Answer:

Step-by-step explanation:

Ordered pair (0, 0) & (0.5, 2.5) will fall on the line of graph

Step-by-step explanation:

Megan expects to save an average of 5 dollars per week from her babysitting earnings.

=> Saving Per week = 5 $

Saving in 0.5 Week = 0.5 * 5 = 2.5 $

hence ordered pair (0.5, 2.5) will fall on the line of graph

Saving in 3 Week = 3 * 5 = 15 $

Hence (3, 18) will not fall on line

Saving in 0 Week = 0.5 * 0 = 0 $

hence ordered pair (0, 0) will fall on the line of graph

Saving in 4.5 Week = 4.5 * 5 = 22.5 $

Hence (4.5, 30) will not fall on line

3) What is 3x +15y=-16 in slope intercept form?

stellarik [79]

Answer:

y=-1/5x-16/15

Step-by-step explanation:

slope intercept form y=mx+b

3x+15y=-16

15y=-3x-16 divide both sides by 15

y=-3/15x-16/15 simplify -3/15 to -1/5

y=-1/5x-16/15

A gambler has a coin which is either fair (equal probability heads or tails) or is biased with a probability of heads equal to 0

yawa3891 [41]

Answer:

(a) 0.1719

(b) 0.3504

Step-by-step explanation:

For every coin the number of heads follows a Binomial distribution and the probability that x of the 10 times are heads is equal to:

$P(x)=\frac{n!}{x!(n-x)!}*p^x*(1-p)^{10-x}$

Where n is 10 and p is the probability to get head. it means that p is equal to 0.5 for the fair coin and 0.3 for the biased coin

So, for the fair coin, the probability that the number of heads is less than 4 is:

$P(x$

Where, for example, P(0) and P(1) are calculated as:

$P(0)=\frac{10!}{0!(10-0)!}*0.5^0*(1-0.5)^{10-0}=0.0009\\P(1)=\frac{10!}{1!(10-1)!}*0.5^1*(1-0.5)^{10-1}=0.0098$

Then, $P(x$ , so there is a probability of 0.1719 that you conclude that the coin is biased given that the coin is fair.

At the same way, for the biased coin, the probability that the number of heads is at least 4 is:

$P(x\geq4 )=P(4)+P(5)+P(6)+...+P(10)$

Where, for example, P(4) is calculated as:

$P(4)=\frac{10!}{4!(10-4)!}*0.3^4*(1-0.3)^{10-4}=0.2001$

Then, $P(x\geq4 )=0.3504$ , so there is a probability of 0.3504 that you conclude that the coin is fair given that the coin is biased.

Can somebody PLEASE HELP ME??? trying to correct answers and i have no clue how to do this.

jek_recluse [69]

Answer:

613 inches

Step-by-step explanation:

Area right triangle = 10,710

Formula for area of a triangle = 1/2(base x height)

We need to find the base because height and area is given

Reverse divide by 2 by doing multiply by 2

10,710 x 2 = 21420

Revers multiply by 612 by dividing by 612

21420 / 612 = 35

Base = 35

Formula for hypotenuse = a² + b² = c²

In this case a = 35, b = 612, and c = hypotenuse

35² + 612² = c²

1225 + 374544 = c²

375769 = c²

Square root of 375769 = 613

Hypotenuse = 613

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!
