<span>Assuming that Josh throws the discus 36 times, the expected value of y will be the length each discus reaches for each throw all added together. Specifically, it will be discus throw one, plus discus throw two -- all the way to discus throw thirty-six. Adding all of those throws together will provide the expected value of Y.</span>

Leya [2.2K]

Answer:

x = -19/2      y = -33/2

Step-by-step explanation:

x - (3x + 12) = 7

x - 3x - 12 = 7

-2x - 12 = 7

-2x = 19

x = -19/2

x - y = 7

-19/2 - y = 7

-y = 33/2

y = -33/2

If we assume that 2010 is t=0 what is the initial value and what does it mean?
timurjin [86]

The initial value is 309.35

It means that in the year 2010 (starting year) the population was 309,350,000 people or written another way "309.35 million". The second way is more short so probably the more preferred method.

To find the value 309.35, simply look at the table under the value t = 0.

LenKa [72]

Answer:

6

Step-by-step explanation:

limit is defined when the limit from both side are defined and equal to f

x-> -10^-, limit f(x)=-4-(-10)=6

f(-10)=6

x-> -10^+, limit f(x)=(-10)+16=6

Then

x->-10, limit f(x)=6

A sporting goods store manager was selling a ski set for a certain price. The manager offered the markdowns​ shown, making the​
Ilya [14]

Answer:

The original selling price would be $ 515.87 ( approx )

Step-by-step explanation:

Let x be the original selling price ( in dollars ),

After marking down 10%,

New selling price = x - 10% of x = x - 0.1x = 0.9x

Again after marking down 30%,

Final selling price = 0.9x - 30% of 0.9x

= 0.9x - 0.3 × 0.9x

= 0.9x - 0.27x

= 0.63x

According to the question,

0.63x = 325

\implies x =\frac{325}{0.63}\approx 515.87

Hence, the original selling price would be $ 515.87.
