Answer:

   [[. . 3 6 .][1 3 4 9 .][9 2 . 7 1][. 1 2 8 3][. 4 9 . . ]]

Step-by-step explanation:

It is helpful to remember that the first four digits {1, 2, 3, 4} total 10, and the last four digits {6, 7, 8, 9} total 30. It is also worthwhile to note that the smallest sum of two digits is 3 = 1+2, and the largest sum of 2 digits is 17 = 8+9. Some sums can only be made one way: 4 = 1+3, 16 = 7+9.

Here, we will refer to rows 1-5 from the top down, and columns 1-5 from the left to right.

__

Based on the above, column 5 can only be made one way: 1+3. Column 4 can only be made one way: 9+8+7+6. Then the choices for row 3B will be 1+7 or 5+3. We know it can't be 5+3 because 5 is not part of column 4. This makes our first fill-in (row, column) be (3,4)=7, (3,5)=1, (4,5)=3.

The sum of the remaining cells in row 4 must be 14-3 = 11, and cell (4,4) must be 6, 8, or 9. It cannot be 9, because that would require the remaining two cells to have a sum of 2, which they cannot. So, cell (4,4) is 6 or 8.

Cell (1,4) cannot be 9, either, because we cannot use 0 in cell (1,3). Then the only place for 9 in column 4 is in cell (2,4)=9.

With cell (1,4) being restricted to 6 or 8 (the two remaining numbers in column 4, cell (1,3) must be 3 or 1, and cell (2,3) must be 4 or 6. It cannot be 6 because that would require a sum of 2 in the first two cells of row 2, so (2,3)=4, (1,3)=3, and (1,4)=6. This makes (4,4)=8 and the remaining two cells of row 4 must be 1 and 2. 1 cannot go in (4,3), so we must have (4,3)=2 and (5,3)=9, (5,2)=4, (4,2)=1. That leaves 2 and 3 for rows 2 and 3 of column 2. The first two cells of row 2 must total 4, so must be 1 and 3. Cell (2,2) cannot be 1, so must be 3, leaving (2,1)=1, (3,1)=9, (3,2)=2 and that completes it.

The fill-ins are ...

   [. . 3 6 .]

  [1 3 4 9 .]

  [9 2 . 7 1]

  [. 1 2 8 3]

  [. 4 9 . . ]

Answer:

D) no solution

Step-by-step explanation:

2x - 4y = 14

X + 2y = 7

2x - 4y + x + 2y = 14 + 7

2x - 4y + x + 2y = 21

3x - 2y = 21

no solution

Answer:

x=2y+7

step by step explanation:

2x-4y=14

2(x-2y)=14

x-2y=14/2

x-2y=7

x=2y+7

The best estimate of the weight of the box in pounds is 2,446.4 pounds.

Given that, a box filled with books weighs 1112 kilograms.

We need to find what is the best estimate of the weight of the box in pounds.

To convert kilograms to pounds, multiply your kilogram measurement by 2.2.

Given, 1 kilogram = 2.20 pounds

Now, 1112×2.2=2,446.4 pounds

≈2,446

Therefore, the best estimate of the weight of the box in pounds is 2,446  pounds.

Step-by-step explanation:

The points [tex]A,B,C[/tex] are collinear and [tex]B[/tex] is in middle of [tex]A,C[/tex], so the expression that can justify the given statement is,

[tex]AB+BC=AC[/tex]

Generally the equation for the Ratio of people  is mathematically given as

[tex]Y=P(\frac{39000-48000}{9000}<z<\frac{57000-48000}{9000})\\\\\Y=P(z<1))-(1-p(z-1))\\\\Y=0.8413-0.1582\\\\\Y=0.6826[/tex]

Step-by-step explanation:

4000 Watts means that if you run the machine for one hour, you are using 4000 watt-hours or more commonly used 4 kWh (kilo means 1000).

for 14 cents per kWh we have then

14 × 4 = 56 cents per day

now, if the other model uses only 2000 Watts and still only needs 1 hour for the same job (which is in reality NOT a given, very often such a machine means that it will have to run close to 2 hours) it would cost

14 × 2 = 28 cents per day, saving 28 cents per day.

for a year running the dryer daily

we would save

28 × 365 = 10220 cents = $102.20 savings per year

Answer:

no its not linear

Step-by-step explanation:

here is one example of a linear equation: y = 5x + 12

Answer:

Please write in english

We have the graph of a function (say f(x)).

We have to determine which of the given statements are correct w.r.t this graph of f(x).

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.

According to the question, we have the equation of this line as -

y = -5.

The value of y is constant for every value of x. Therefore, the range of the function is Set → {- 5}.

The function has same value → y= -5 for all values of x, ranging from →

- ∞ to + ∞, Therefore, its domain is the set of all Real numbers.

A function can have same value of y for different values of x.

Hence, Option B and D are correct.

Answer:

Step-by-step explanation:

They want u to find MR, and I can do that by taking CR - CM

But first we need to know what is x

Now u know CM + MR =CR

Therefore

(3x - 2) + (x+8) = 46

3x - 2 + x + 8 = 46

4x + 6 = 46

4x = 40

x = 10

Now we know x is 10, let's just make it easier first

CM = 3x-2

= 3 (10) - 2

= 28

MR = x + 8

= 10 + 8

= 18

Now we got all our values

They want MR?

MR = x + 8

= 10 + 8

= 18

HERE U GO

Answer:

18

Step-by-step explanation:

cm=3x -2

mr=x +8

cr=46

cm+mr=cr

3x-2+x+8=46

4x+6=46

4x=46-6

x=40/4

x=10

hence, mr=x+8

=10+8

=18
