Answer with explanation:

Pascal Triangle is Associated with finding the value of nth power of sum or difference of two variables.

The Expression

                (a\pm b)^n, has n+1 , terms.

1-(a+b)^0=1\\\\2-(a+b)^1=a+b\\\\3-(a+b)^2=a^2+2 a b+b^2\\\\4-(a+b)^3=a^3+3a^2b+3ab^2+b^3\\\\5-(a+b)^4=a^4+4a^3b+6a^2b^2+4ab^3+b^4\\\\.......

Now expressing the expression in the form of Pascal's Triangle

                                            1

                                        1                1

                               1              2(1+1)               1

                          1            3(2+1)               3(2+1)            1

                 1            4(3+1)              6 (3+3)             4(3+1)         1

        1         5 (4+1)            10(6+4)            10 (6+4)            5(4+1)       1

1      6(5+1)       15(10+5)      20 (10+10)        15(10+5)        6(5+1)       1

1   7(6+1)   21 (15+6)    35 (20+15)  35(20+15)    21(15+6)  7(6+1)       1

Eight Row is Required to expand the expression →→

      (2x^3+3y^2)^7

I am Lyosha [343]

Answer:

$43.75

Step-by-step explanation:

So you have: 35% discount

Total without discount: $125.00

Amount discounted: ?

So you have to make 35% into a number that you can multiply with $125. When you have a percentage you move the decimal two times to the front so you have 0.35 then you multiply;

125 x 0.35 = 43.75.

43.75 is the amount discounted, so you only have to pay 81.25. The equation for that would look like;

125 - 43.75 = 81.25

Hope that made sense!

marusya05 [52]

Answer:

Step-by-step explanation:

Confidence interval is written in the form, sample mean ± margin of error

The sample mean is an estimator for the population mean. The confidence level is used to express how confident we are that the population mean is within the calculated confidence interval. The lower limit of the given confidence interval is 2.619 hours/day while the upper limit of the confidence interval is 3.401 hours/day

Therefore, the INVALID interpretations of the 95% confidence interval are

A. About 95% of all Cal Poly students spend between 2.619 and 3.401 hours/day watching TV.

B. There is a 95% chance that, on average, Cal Poly students spend between 2.619 and 3.401 hours/day watching TV.

D. In the long run, 95% of the sample means will be between 2.619 and 3.401 hours.

E. None of the above.

a ball is thrown straight up from the top of a tower that is 280 ft high with an initial velocity of 48 ft/s . the height of the
poizon [28]
First find the time that the ball is level with the top of the building on its descent. You can do this by  solving 280 = -16^2 + 48t + 280 for t. This gives t = 3 seconds . 
Then when the ball reaches the ground the  time t is obtained by solving 0 = -16t^2 + 48t + 280  This gives t = 5.94 seconds.
Answer in interval notation is  (3, 5.94].

The rabbit population on a small island is observed to be given by the function P(t) = 130t − 0.3t^4 + 1100 where t is the time
Montano1993 [528]
The maximum occurs when the derivative of the function is equal to zero.
P(t)=-0.3t^{4}+130t+1100 \\ P'(t)=-1.2t^{3}+130 \\ 0=-1.2t^{3}+130 \\ 1.2t^{3}=130 \\ t^{3}= \frac{325}{3}  \\ t=4.76702
Then evaluate the function for that time to find the maximum population.
P(t)=-0.3t^{4}+130t \\ P(4.76702)=-0.3*4.76702^{4}+130*4.76702+1100 \\ P(4.76702)=1564.79201
Depending on the teacher, the "correct" answer will either be the exact decimal answer or the greatest integer of that value since you cannot have part of a rabbit.
