Sarah is 40 years old and her mother is 64 years old.

Answer:

Step-by-step explanation:

A survey of 8225 Americans included age data collection.

The mean age was recorded as 42, whereas the median was noted as 37.

This indicates median < mean.

When the mean exceeds the median, it suggests the presence of right skewness in the data.

In a symmetrical distribution, mean and median align. If there is a discrepancy, the distribution is skewed.

Consequently, with the mean > median, the data is skewed to the right.

Answer:

Step-by-step breakdown:

The necessary formula for this problem is

which resolves to

leading to

36 + 6x = 40 + 5x, and consequently

x = 4

Thus, DG equals 5 + 4 + 3, resulting in 12

Answer:

The total of all exterior angles in BEGC equals 360° ⇒ only answer F is correct

Step-by-step explanation:

* Let’s review some basics regarding quadrilaterals

- A quadrilateral is a polygon that has four sides

- The interior angles of any quadrilateral add up to 360°

- The exterior angles of any quadrilateral also total 360°

* Now let’s tackle the problem

- DEGC is indeed a quadrilateral

∵ m∠BEG = (19x + 3)°

∵ m∠EGC = (m∠GCB + 4x)°

∵ The total of the interior angles measures 360°

∴ m∠BEG + m∠EGC + m∠GCB + m∠CBE = 360

∴ (19x + 3) + (m∠GCB + 4x) + m∠GCB + m∠CBE = 360 ⇒ combine like terms

∴ (19x + 4x) + (m∠GCB + m∠GCB) + m∠CBE + 3 = 360 ⇒ subtract 3 from both sides

∴ 23x + 2m∠GCB + m∠CBE = 375

∵ The exterior angles of any quadrilateral will always sum to 360°

∴ Only the statement in answer F holds true
