Jack works as a waiter and is keeping track of the tips he earns daily. about how much does jack have to earn in tips on sunday

OLga [1]

A mean is an arithmetic average of a set of observations. The amount that Jack has to earn in tips on Sunday if he wants to average $19 a day is $25.

A mean is an arithmetic average of a set of observations. it is given by the formula,

$\rm Mean=\dfrac{\text{Sum of all obervation}}{\text{Number of observation}}$

As it is given that Jack makes $12 on Monday, $14 on Tuesday, $18 on Wednesday, $16 on Thursday, $26 on Friday and $22 on Saturday. And we need to know how much he should earn on Sunday, so the average is $19. Therefore, we can write,

$\rm Mean=\dfrac{\text{Sum of all obervation}}{\text{Number of observation}}$

$19 = \dfrac{12+14+18+16+26+22+x}{7}\\\\133 = 108 + x\\\\133-108=x\\\\x = 25$

Hence, the amount that Jack has to earn in tips on Sunday if he wants to average $19 a day is $25.

What else would need to be congruent to show that ABC= ADEF by SAS?

Travka [436]

Answer:

Option C.

Step-by-step explanation:

It is given that,

$\overline{AB}\cong \overline {DE}$

$\overline{AC}\cong \overline {DF}$

According to SAS congruence property, two triangles are congruent if they have two congruent corresponding sides and their included angles are congruent.

Angle between $\overline{AB}\text{ and }\overline {AC}$ is $\angle A$ .

Angle between $\overline{DE}\text{ and }\overline {DF}$ is $\angle D$ .

So, $\Delta ABC\cong \Delta DE F$ by SAS, if

$\angle A\cong \angle D$

Therefore, the correct option is C.
