Someone please help me with this question! How can I prove it?

Alex73 [517]

Answer:

TS=QV

Step-by-step explanation:

To prove SAS congruence, you need to prove that two lines and the angle between them are all respectively equal.

In the diagrams we already have RS=WV and ∠RST=∠WVQ, so it follows that we need to prove that TS=QV.

The amount of gasoline sold each month to customers at Bob's Exxon station in downtown Navasota is a random variable. This rando

swat32

Answer:

The probability that Bob will win that wonderful trip on the basis of his gasoline sales this month

P(X≥ 2800) = P(Z₁≥1.5) = 0.0768

Step-by-step explanation:

Step(i):-

Mean of the Population (μ) = 2500 gallons

Standard deviation of the population (σ) =200 gallons

Let 'X' be a random variable in Normal distribution

Given X = 2800

$Z = \frac{x-mean}{S.D} = \frac{2800-2500}{200} = 1.5$

Step(ii):-

The probability that Bob will win that wonderful trip on the basis of his gasoline sales this month

P(X≥ 2800) = P(Z₁≥1.5)

= 0.5 - A(Z₁)

= 0.5 - A(1.5)

= 0.5 -0.4232 ( from normal table)

= 0.0768

Conclusion:-

The probability that Bob will win that wonderful trip on the basis of his gasoline sales this month

P(X≥ 2800) = P(Z₁≥1.5) = 0.0768

How many times does a rabbits heart beat in one hour

mash [69]

A rabbit’s heart rate should be 120-150 beats per minute so you just multiply 120 by 60 and 150 by 60 and the numbers in between that should be the amount of times a rabbit hearts beats in one hour. 60 x 120 = 7,200 and 60 x 150 = 9,000. A rabbit's heart beats between 7,200 and 9,000 times an hour.
