3x = 1
3x = 33
7x – 2 = 19
2x = 5
5x = 15
5x + 6 = 21

Answers

Answer:

7x-2=19

5x=15

5x+6=21

................

Step-by-step explanation:

Here x = 3

3x = 1 (False)

3* 3 ≠1

3x = 33 (False)

3 *3 ≠ 33

7x - 2 =19 (True)

7 *3 - 2 = 19

21 - 2 = 19

19 = 19

2x = 5 (False)

2 *3 ≠ 5

5x = 15 (True)

5 * 3 = 15

15 = 15

5x + 6 = 21 (True)

5 * 3 + 6 = 21

15 + 6 = 21

21 = 21

Factor the expression to find the zeros

Answers

Answer:

k = (1 , 4)

Step-by-step explanation:

here's your solution

==> k^2 - 5k + 4. [ is expression ]

==> by using middle term split

==> k^2 - 4k - k + 4

==> taking common from each

==> k(k - 4) - 1 (k - 4)

==> (k - 1) , (k - 4).

==> k - 1 = 0

==> k = 1

==> k - 4 = 0

==> k = 4

hence , k = (1 , 4)

Answer:

The length of the box is 6 cm. The width of the box is 3 cm. The height of the box is 2 cm.

Step-by-step explanation:

volume = length x width x height In this instance volume = 36 m³. I will let “b” be the length of the box. “w’ will be the width of the box. And “h” will be the height of the box. Therefore we know that b = 2w and b=3h. So: w= b /2 and h=b /3.

36 m³= b(b/2)(b/3)

36 = b³/6

b ³ = 216

b = 6

w = 6/2 = 3

h = 6/3 = 2

Answers

Answer:

number 1 the outliers....................

Answer:  B) The distribution is symmetric

Explanation:

The center of the distribution is the highest point. As you move to the left or right, the heights of each bar steadily decrease. Notice that the right hand side is a mirror copy of the left hand side. This mirroring is exactly what it means to be symmetric. If we had outliers, then we'd have bars that are further away from the main group, but we don't have such a thing happening here.

If the distribution was skewed left, or negatively skewed, then we'd have outliers that are smaller than the main group. On the other hand, if we had a skewed right (positively skewed) distribution, then we'd have outliers larger than the main group. We don't have any of these cases happening, so that's why the data isn't skewed in any way.

In the number 3.9928, how does the value of the 9 in the tenths place compare to the value of the 9 in the hundredths place?

Answers

Answer:

the 9 in the tenths place is 10 times more than the one in the hundredths place

Step-by-step explanation:

Given that

There is a number i.e. 3.9928

Here we need to compare the value of the 9 in the tenth place to the value of the 9 in the hundredth place

The 9 in the tenth place has a value of 0.9

And, The value of 9 in the hundredth place contains a value of 0.09

So,

= 0.09 ÷ 0.9

= 0.1

= 1 ÷ 10
