Answer:

Step-by-step explanation:

6(3x – 8) = 7(7x + 7)

18x - 48 = 49x + 49

49x - 18x = - 48 - 49

31x = - 97

x = - 97/31

Answer:

x = -3.13

Step-by-step explanation:

6(3x – 8) = 7(7x + 7)

18x - 48 = 49x + 49

subtract 18x from from each side

-48 = 31x + 49

add 48 to each side

31x +97 = 0

31x = -97

divide both sides by 31

x = -3.13

check:

6(3[-3.13] - 8) = 7(7[-3.13] + 7)

-104.35 = -104.35

Answer:

✔️2 sets of corresponding angles

<D and <S

<R and <L

✔️2 sets of corresponding sides

DR and SL

RM and LT

Step-by-step explanation:

When two polygons are congruent, it implies that they have the same shape and size. Therefore, their corresponding angles and sides are congruent to each other.

When naming congruent polygons, the arrangement of the vertices are kept in a definite order of arrangement.

Therefore, Given that polygon DRMF is congruent to SLTO, the following angles and sides correspond to each other:

<D corresponds to <S

<R corresponds to <L

<M corresponds to <T

<F corresponds to <O

For the sides, we have:

DR corresponds to SL

RM corresponds to LT

MF corresponds to TO

FD corresponds to OS.

We can select any two out of these sets of corresponding angles and sides as our answer. Thus:

✔️2 sets of corresponding angles

<D and <S

<R and <L

✔️2 sets of corresponding sides

DR and SL

RM and LT

From a population of 200,000,000 elements, the standard deviation is known to be 14. A sample of 49 elements is selected. It is
Talja [164]

Answer:

The standard error of the mean = 2

Step-by-step explanation:

Given that:

The standard deviation σ = 14

The sample size n = 49

The sample mean \overline x = 56

The formula for calculating the standard error can be expressed as:

S.E = \dfrac{\sigma}{\sqrt{n}}

S.E = \dfrac{14}{\sqrt{49}}

S.E = \dfrac{14}{7}

S.E = 2

Therefore, the standard error of the mean = 2
