Calculate the distance between Points A and B.<br> A.4.5<br> B.7.1<br> C.7.8<br> D.9.2

storchak [24]

Answer:

7.8 units separate the points A and B.

Step-by-step explanation:

Going from B to A, x increases by 6 (this is the horizontal side of the triangle formed by vertices A and B), and y increases by 5. Applying the Pythagorean Theorem, we get

d = √(6² + 5²), or √(61, which is approximately 7.8, the desired distance.

6) Mrs. Hesabu has taken a loan of sh. 400,000 from Sweet

PIT_PIT [208]

Answer:

Step-by-step explanation:

If she was given a discount of 12% then the amount to be paid becomes I=P×R×T/100

I=400000×12×20/100

I=960000

Amount to be paid =I +P= 960000+400000=1360000

To liquidate this amount in 20 years therefore will be A÷20

1360000÷20

=68000 yearly

A company offers a raffle whose grand prize is a $35,000 new car. Additional prizes are a $1,100 television and $600 computer. T

anastassius [24]

Answer:

-$ 10.13

Step-by-step explanation:

Given,

The cost price of each ticket = $ 22,

So, the value of each ticket other than price ticket = - $ 22, ( negative sign shows loss,i.e. if we don't get the price we will have the loss of $ 22 )

Now, there are 3 tickets in which first is of $35,000 price, second is of $1,100 and third is of $ 600,

So, the value of first ticket = 35000 - 22 = $ 34978,

Value of second ticket = 1100 - 22 = $ 1078,

Value of third ticket = 600 - 22 = $ 578,

Also,

$\text{Probability}=\frac{\text{Favourable outcome}}{\text{Total outcome}}$

Hence, by the above information we can make a table for the given situation,

Number 2997 1 1 1

Price -$ 22 $ 34978 $ 1078 $ 578

Probability 2997/3000 1/3000 1/3000 1/3000

Therefore, the expected value of a ticket

$=-22\times \frac{2997}{3000}+34978\times \frac{1}{3000}+578\times \frac{1}{3000}$

$=-$10.126$

≈ - $ 10.13
