Answer:

Part A

Yes

Part B

He will land at a point 30 meters from Cannon

Step-by-step explanation:

Part A

The given function that represent the path of the Cannon, which is the path of a parabolic arc, is presented as follows;

f(x) = -0.05·(x² - 26·x - 120)

We note that the height, 'h', of the path of a parabola at a horizontal distance, 'x' from the origin is equal to f(x)

Therefore, given that at the ground level, at the start and end of the flight, the f(x) = 0, we can write;

-0.05·(x² - 26·x - 120) = 0

∴ x² - 26·x - 120 = 0

x = (26 ± √((-26)² - 4 × 1 × (-120)))/(2 × 1)

Which gives;

x = 30 or x = -4

Therefore, he lands at a point 30 meters from the starting point

Therefore, the function gives enough information to tell where he will land

Part B

He lands at the point, x = 30 from the point the cannon was fired.

Answer:

∫ C ( y + e√x) dx  +  ( 2x + cosy² ) dy = 1/3

Step-by-step explanation: See Annex

Green Theorem establishes:

∫C ( Mdx  +  Ndy )  = ∫∫R ( δN/dx  -  δM/dy ) dA

Then

∫ C ( y + e√x) dx  +  ( 2x + cosy² ) dy

Here

M = 2x  + cosy²           δM/dy  =  1

N = y + e√x                 δN/dx  =  2

δN/dx  -  δM/dy  =  2  -  1   = 1

∫∫(R) dxdy   ∫∫ dxdy

Now integration limits  ( see Annex)

dy  is from   x  = y²    then     y = √x    to  y = x²   and for dx

dx   is from 0   to  1 then

∫ dy    = y | √x   ;   x²      ∫dy    =  x² - √x

And

∫₀¹ ( x² - √x ) dx    =  x³/3  - 2/3 √x |₀¹    =   1/3 - 0

∫ C ( y + e√x) dx  +  ( 2x + cosy² ) dy = 1/3

A) The higher the grade, the larger the average donation

Answer:

The Answer is A

Step-by-step explanation:

Answer:

The domain is the set of x-values:

The range is the set of y-values:

This is in contrast to theoretical probability where it's what we think would happen, or predict to happen.

For example, the theoretical probability of getting heads on a coin is 1/2 = 0.50 = 50%. If you flip a coin say 1000 times and get 400 heads, then the empirical or experimental probability of getting heads is 400/1000 = 0.40 = 40%. The experimental probability is what actually happens when you do the experiment. The theoretical probability is what you predict what would happen given some list of assumptions and rules about the object.

According to the law of large numbers, the experimental probability should get closer and closer to the theoretical one assuming the theoretical probability has been calculated properly (and all assumptions are correct). If we got say 475 heads instead of 400, then we might have fairly good evidence that we have a fair coin (since 475/1000 = 0.475 is fairly close to 0.500); however, if we got something like 300 heads then we might suspect that the coin is biased toward tails than it is toward heads. The more trials you do, the better a picture you can get of it.

Answer:

100times

Step-by-step explanation:

theoretically it would be a 50/50 so I would expect them to match 50% of the time or 100 times

Answer:

D. 1.5

Step-by-step explanation:

The median number of excused absences from given data is 1.5.

We have given that,

The dot plot below shows the number of excused absences students in Mr. Beckett's class have.

We have to determine the median

The median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as the middle value.

Therefore the median number of excused absences from given data is 1.5.

Therefore option D is correct.

Answer:

y = ½x + 8

Step-by-step explanation:

✔️First, find the slope (m) using any two given pairs of values, say (0, 8) and (2, 9):

Slope (m) = change in y/change in x

Slope (m) = (9 - 8)/(2 - 0)

Slope (m) = 1/2

m = ½

✔️Find the y-intercept (b):

The y-inteeceot of the function would be the value of y when x = 0.

Form the table, when x = 0, y = 8. Therefore:

y-intercept (b) = 8

✔️To write the equation of the function, substitute m = ½ and b = 8 into y = mx + b.

Thus:

y = ½x + 8

Answer:

The proportion of sampled students that complete their degree is 0.791.

Step-by-step explanation:

A proportion is the number of desired outcomes divided by the number of total outcomes.

a)Calculate the proportion of sampled students that complete their degree.

110 students sampled.

87 went on to complete their degree.

p = 87/110 = 0.791

The proportion of sampled students that complete their degree is 0.791.
