What is the reciprical of 200 and 450​

Mathematics
1 answer:
Bad White [126]3 years ago
3 0

Answer:

Part a) \frac{1}{200}

Part b) \frac{1}{450}

Step-by-step explanation:

we know that

A reciprocal of a rational number  \frac{p}{q}  is obtained by changing the numerator and denominator, so the numerator becomes the denominator and the denominator becomes the numerator obtaining  \frac{q}{p}

Part a) we have

200

we know that

the given number can be expressed as \frac{200}{1}

so

changing the numerator and denominator

The reciprocal is equal to \frac{1}{200}

Part b) we have

450

we know that

the given number can be expressed as \frac{450}{1}

so

changing the numerator and denominator

The reciprocal is equal to \frac{1}{450}

Answer:

there is no solution for these linear equations in two variables.

since a1 (y) = a2 (y)

         b1 (5x) = b2 (5x)

  but, c1 (12) not equal to c2 (18)

Answer:

19 feet

Step-by-step explanation:

A right triangle is formed by the slant height, the radius of the base and with the slant height being the hypotension

The square on the hypotension is equal to the sum of the squares on the other 2 sides, that is

Since base diameter = 30then radius = 15

The mean time it takes to walk to the bus stop is 8 minutes (with a standard deviation of 2 minutes) and the mean time it takes
kifflom [539]

We have been given for a normal distribution the mean time it takes to walk to the bus stop is 8 minutes with a standard deviation of 2 minutes. And the mean time it takes for the bus to get to school is 20 minutes with a standard deviation of 4 minutes.

(a) Average time that it would take reach school can be obtained by adding the average times.

8+20 = 28 minutes.

(b) Standard deviation of the trip to school can be found as:

\sigma =\sqrt{2^{2}+4^{2}}=\sqrt{4+16}=\sqrt{20}=4.47

Therefore, standard deviation of the entire trip is 4.47 minutes.

(c) Let us first find z score corresponding to 30 minutes.z=\frac{x-\mu }{\sigma }=\frac{30-28}{4.47}=0.447

We need to find the probability such that P(x>30)=P(z>0.447)=0.67

Therefore, the required probability is 0.67.

(d) If average time to walk to school is 10 minutes, then overall average time for the trip will be 10+20 = 30 minutes.

(e) Standard deviation won't change it will remain 4.47

(f) The new probability will be:

z=\frac{x-\mu }{\sigma }=\frac{30-90}{4.47}=0

P(x>30)=P(z>0)=0.5

Therefore, probability will be 0.50.
