Answer:

A. The first choice.

Step-by-step explanation:

Look at function 1.

Month 1 -----> $50

Month 2 ----> $40

The difference between month 2 and moin th 1 is 1 month.

The difference between $40 and $50 is -$10. In other words, in function 1, the amount, y, went down $10 in a month. The rate of change of function 1 is -$10/month.

Function 2

y = -9x + 60

The rate of change is the slope. The slope of function 2 is -9. In function 2, the amount of money changes -$9/per month.

Answer: A. The first choice.

sdas [7]

Answer:

I have given it step by step below.

Step-by-step explanation:

(i) Mean = sum of observations/total no. of observation

= 23 + 20 + 4 + 19 + 28 + 35 + 25 + 0 +1 + 30/ 10

= 185/10

= 18.5

(ii) additional 35 runs

New Mean

=previous total + 35/10 + 1 (the 1 gets added in denominator because of the additional observation)

= 185 + 35/11

= 220/11

= 20

Hope this helps you!

Christina scored a certain number of goals, g, during a soccer season. Sarah scored twice as many goals during the same season.

Norma-Jean [14]

S=2g or y=2x because you are multiplying Christina score by two to get Sarah's score.

iren [92.7K]

Answer:

Option D.

Step-by-step explanation:

In the figure attached, Diagonals AC and BD are bisecting each other at a point P.

That means AP ≅ CP and DP ≅ BP

We have to prove : AB ≅ DC and AB ║ DC

Proof : In triangles BPA and CPD,

AP ≅ CP

DP ≅ BP

∠ APB ≅ ∠DPC [vertically opposite angles]

Therefore, by postulate SAS [Side-Angle-Side]

ΔBCP ≅ ΔCDP

Option D. will be the answer.
