The data to represent average test scores for a class of 16 students includes an outlier value of 78. If the mean, including the
monitta

Answer:

Given that The data to represent average test scores for a class of 16 students includes an outlier value of 78.

We can find sum of all 16 test scores = 84(16) = 1344

Outlier found = 78

If outlier is removed new sum = 1344-78 = 1266

Number of entries without outlier = 15

New average = 1266/12 =84.4

We find that average of new data increases.

Also whenever we remove outlier std deviation also would be reduced.

I don't understand this factorisation <br> a2+ 4a+3​
Tomtit [17]

Answer:

\boxed{\sf (a + 3)(a + 1)}

Step-by-step explanation:

\sf Factor  \: the  \: following:  \\  \sf \implies  {a}^{2}  + 4a + 3 \\  \\  \sf The \:  factors  \: of \:  3 \:  that \:  sum \:  to \:  4  \\ \sf are \:  3  \: and  \:  1. \\ \\  \sf So,  \\   \sf \implies {a}^{2}  + (3 + 1)a + 3 \\  \\  \sf \implies   {a}^{2}  + 3a + a + 3 \\  \\  \sf \implies a(a + 3) + 1(a + 3)  \\  \\ \sf \implies (a + 3)(a + 1)

the derivative of the function f is given by f'(x)=x^2cos(x^2). How many points of inflection does the graph of f have on the op
Vsevolod [243]
The point of inflection is calculated by equating the second derivative to zero and determining x from there.

f"(x) = -x²2xsinx² + cosx²(2x) = 0

2xcosx² - 2x³sinx² = 0
2x (cosx² - xsinx²) = 0

2x = 0   ⇒  x = 0
cosx² - xsinx² = 0   ⇒ x = 3.82 (if you use shift+solve in your scientific calculator)

Thus, the function only has 1 point of inflection and it is at x = 0.
