Answer:

4

Step-by-step explanation:

We assume you're asking the difference between the digits of a two-digit number such that reversing the digits makes the value different by 36.

The difference between the digits is 36/9 = 4.

__

The value difference is always 9 times the digit difference.

Can someone help me find surface area??

natita [175]

Answer:

277cm²

Step-by-step explanation:

Base = 9x8=72

There are 2 triangles with a bottom edge of 9 and a slant height of 13:

1/2(9)(13)=58.5

There are 2 triangles with a bottom edge of 8 and a slant height of 11:

1/2(8)(11)=44

72+58.5+58.5+44+44=277cm²

Johns dog slept for 3 hours if the dog snored every 1/3 of an hour how many times did he snore

Licemer1 [7]

The dog snored nine times. 1/3 of an hour is every 30 minute interval. 30 min + 30 min = 1 hour. Multiply this x3, and the answer is nine. A simpler way of thinking about this is 3 x 3 or 3 squared.

Consider writing onto a computer disk and then sending it through a certifier that counts the number of missing pulses. Suppose

Furkat [3]

Answer:

a) 0.164 = 16.4% probability that a disk has exactly one missing pulse

b) 0.017 = 1.7% probability that a disk has at least two missing pulses

c) 0.671 = 67.1% probability that neither contains a missing pulse

Step-by-step explanation:

To solve this question, we need to understand the Poisson distribution and the binomial distribution(for item c).

Poisson distribution:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}
$

In which

x is the number of sucesses

$
e = 2.71828$ is the Euler number

$\mu$ is the mean in the given interval.

Binomial distribution:

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

Poisson mean:

$\mu = 0.2$

a. What is the probability that a disk has exactly one missing pulse?

One disk, so Poisson.

This is P(X = 1).

$P(X = 1) = \frac{e^{-0.2}*0.2^{1}}{(1)!} = 0.164
$

0.164 = 16.4% probability that a disk has exactly one missing pulse

b. What is the probability that a disk has at least two missing pulses?

$P(X \geq 2) = 1 - P(X < 2)$

In which

$P(X < 2) = P(X = 0) + P(X = 1)$

In which

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}
$

$P(X = 0) = \frac{e^{-0.2}*0.2^{0}}{(0)!} = 0.819$

$P(X = 1) = \frac{e^{-0.2}*0.2^{1}}{(1)!} = 0.164
$

$P(X < 2) = P(X = 0) + P(X = 1) = 0.819 + 0.164 = 0.983$

$P(X \geq 2) = 1 - P(X < 2) = 1 - 0.983 = 0.017$

0.017 = 1.7% probability that a disk has at least two missing pulses

c. If two disks are independently selected, what is the probability that neither contains a missing pulse?

Two disks, so binomial with n = 2.

A disk has a 0.819 probability of containing no missing pulse, and a 1 - 0.819 = 0.181 probability of containing a missing pulse, so $p = 0.181$

We want to find P(X = 0).

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 0) = C_{2,0}.(0.181)^{0}.(0.819)^{2} = 0.671$

0.671 = 67.1% probability that neither contains a missing pulse

I can’t figure this out, any help?

saveliy_v [14]

if the spinner is fair , it will land on green for 60 times , there are 24% chances for the spinner to land on purple ,For 1000 spins it will land 150 times on blue

<h3>What is Probability ?</h3>

Probability can be defined as the study to predict the likelihood of an event.

It has a range from 0 to 1.

Probability if the spinner is fair is 1/5 for each colour.

As it is spun 300 times

(1/5) * 300 = 60 times

So if the spinner is fair , it will land on green for 60 times.

(b) The probability of landing on purple theoretically is 60times , 20 % chances

but it can be seen from the data provided that for 300 spins , the spinner landed for 72 times

which is 24% , i.e. there are 24% chances for the spinner to land on purple.

(c)Theoretically blue has 20% chances 200 times , But it is seen in the data obtained that

for 300 spins the spinner is landing on blue for 45 times.

For 1000 spins it will land 1000*45/300 = 150 times.

What is the product of (7 x 10^-5) x (5 x 10^-8) <br> (7 x 10^-5) x (5 x 10^-8) = ? x 10^?

arsen [322]

Answer:

$3.5\times10^-^1^2$

Step-by-step explanation:

$(7 \times 10^-5) \times (5 \times 10^-8)$

Evaluate

$(7 \times 5)\times(10^-^5\times10^-^8)$

$35\times10^-^5^-^8$

$35\times10^-^1^3$

$35\times10^1\times10^-^1^3$

$3.5\times10^1^-^1^3$

$3.5\times10^-^1^2$

Thus, the answer is $3.5\times10^-^1^2$
