The answer of 3542=48, if the given is 1243=21 , 2415=36, 3241=25, 4521=27.

Step-by-step explanation:

The given is,

              1243=21

              2415=36,

              3241=25,

              4521=27

Step:1

          For, 1243 = 21

          Above is solved by,

                    (1+2)×(4+3)=21

                           (3)×(7)=21

                                 21=21

          For, 2415 = 36

          Above is solved by,

                    (2+4)×(1+5)=21

                           (6)×(6)=36

                                36=36

          For,3241= 25

          Above is solved by,

                    (3+2)×(4+1)=25

                           (5)×(5)=25

                                25=25

          For, 4521= 27

          Above is solved by,

                    (4+5)×(2+1)=27

                           (9)×(3)=27

                                 27=27    

           For, 3542 = ?

          Above is solved by,

                                     = (3+5)×(4+2)

                                     =(8)×(6)

                            3542=48

Result:

       The answer of 3542=48, if the given is 1243=21 , 2415=36, 3241=25, 4521=27.

If the critical z-value for a hypothesis test... If the critical z-value for a hypothesis test equals 2.45, what value of the te
schepotkina [342]

Answer: z score = 0.00714

Step-by-step explanation: the value of test statistics is gotten using the standard normal distribution table.

Z= 2.45 has area to the left (z<2.45) and area to the right (z>2.45).

Level of significance α is the probability of committing a type 1 error. The area under the distribution is known as the rejection region and it is the area towards the right of the distribution.

The table I'm using is towards the left of the distribution.

But z>2.45 + z<2.45 = 1

z> 2.45 = 1 - z<2.45

But z < 2.45 = 0.99286

z > 2.45 = 1 - 0.99286

z >2.45 = 0.00714

Hence the test statistics that would produce the least type 1 error is 0.00714

When I double my number add 4 and then subtract my number and subtract three I get my number plus one what is my number?
Lady bird [3.3K]
2 because once you double it, it becomes 4. Once you add 4, you get 8. When you subtract your number, which is 2, you get 6. Then when you subtract 3, you get 3. 3 is your number (2) plus 1

Draw a rectangle on a coordinate plane. Choose a scale factor of 2,3,4, or 5, and then dilate the rectangle. How many times grea
TEA [102]
If you have a rectangle that is 2 by 2 and you dilate it by 2, the sides are now 4 x 4. So:
If you dilate it by a factor of 2, the area is 2^2 (4) times as great
A factor of 3 would have an area of 9 times as much.

Conclusion: square the scale factor to get how much greater the area would be.

Happy Store realizes a mark-up of PhP3,450 in selling TV sets. If its items are sold at a
Anna007 [38]

Answer:

Below is the answer.

Step-by-step explanation:

let s = the selling price.

the selling price presumably includes the cost plus the mark up plus the anticipated profit.

you have s = c + m + p

since m = 3450 and m = .4 * s, then you get:

.4 * s = 3450.

solve for s to get = 3450 / .4 = 8625.

your equation of s = c + m + p becomes:

8625 = c + 3450 + p

you don't know what p is supposed to be.

you don't know what c is supposed to be.

you need p to solve for c.

you need c to solve for p.

the best you can do is solve for c in terms of p, or solve for p in terms of c.

solving for c in terms of p gets you:

c = 8625 - 3450 - p which becomes c = 5175 - p

solving for p in terms of c gets you:

p = 8625 - 3450 - c which becomes p = 5175 - c.

you say that overhead expenses are 27% of the cost.

does this assume that overhead expenses are included in the cost.

regardless, if you don't know the cost, you can't solve for the overhead expenses.

i don't think you can solve this problem with the information given.

you might want to check to see if you're missing some information required to solve it.
