Answer:

B

Step-by-step explanation:

Using the midpoint formula

midpoint = [\frac{1}{2}(x_{1} + x_{2}), \frac{1}{2}(y_{1} + y_{2}) ]

with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (6, - 4)

midpoint = [\frac{1}{2}(- 2 + 6), \frac{1}{2}(4 - 4) ]

               = (2, 0) → B

There are 2 order pairs there (6,-4),(-2,4)
find the midpoint using the formula

(x1+x2)/2 , (y1+y2)/2
x=6 and -2
y=-4 and 4

(6+2)/2 , (-4+4)/2
8/2 ,0/2
the midpoint is (4,0) A

a man has 25 coins in his pocket all of which are dimes and quarters. if the total value of his change is 430 cents, how many di
valentinak56 [21]

Answer:16 quarters and 3 dimes

Step-by-step explanation:

430/25 (Quarters) = 17

25x16

(Because you can’t have 17 since 25x17=425 leaving no room for dimes.)

=400

Now 430-400=30

30 more cent is needed,

30/10(Dime value)

Is 3, so the answer is the man has 16 quarters and 3 dimes

Miss Berk has 8 pairs of pajama pants and 3 pairs of slippers. Three pairs of the pajama pants are Harry Potter themed and one p
shusha [124]

The probability that both items will be Harry Potter themed is 1/8.

<u>Step-by-step explanation:</u>

Total Number of pajama pants n(P) =8

Total number of slippers n(S)= 3

Number of Harry Potter themed Pajama pants n(H.P)=3

Number of Harry Potter themed slippers n(H.S)=1

We have to determine the probability of selecting pants and slippers that are both Harry Potter themed.

If two events A and B are independent, then the probability of A and B is given by

P(A and B)=P(A)*P(B)

Here the events selecting Harry potter themed pants and selecting harry Potter themed slippers are independent.

P(Harry\ Potter\ pants)=\frac{n(H.P)}{n(P)}

                                       =\frac{3}{8}

P(Harry\ Potter\ slippers)=\frac{n(H.S)}{n(S)} \\                                         =1/3

P(Harry\ Potter\ pants\ and\ Harry\ Potter\ slippers)=P(Harry Potter pants)\times P(Harry potter slippers)

=\frac{3}{8}\times  \frac{1}{3} =\frac{1}{8}

Hence probability of selecting Harry potter themed pants and Harry potter themed slippers is 1/8

Samson opened a bank account with 1.25% simple interest. The total amount of interest Samson will earn after 20 years is $812.50
IRINA_888 [86]
<h2>$650</h2>

Step-by-step explanation:

       The principal amount recieves a simple interest every year. The simple interest rate is given as 1.25\%.

       It is given that the total amount after 20  years is $812.50

       Total=Principal+Interest\textrm{ = }P+P\times i\times T

Here P is the principal amount, i is the interest rate, T is the time period.

       812.50=P+P\times (1.25\times \frac{1}{100})\times 20yr=P\times 1.25\\P=650\$

∴ Samson had $650 when he opened the account.
