Consider the following.f(x)=74 – x2Find the x-values at which f is not continuous. Which of the discontinuities are removable?

tensa zangetsu [6.8K]

Answer

given,

f(x) = 74 - x²

A function is continuous when it is differential at all the points.

$f'(x) =\dfrac{d}{dx}(74-x^2)$

$f'(x) =- 2 x$

so, the given function is continuous for all the value of x.

We should know that if a function is quadratic then it is differential at all the point. And if it is differential then it is definitely continuous.

Hence, there is no discontinuous point present in the equation.

X is at most 30 represent as an algebraic inequality

masya89 [10]

Answer:

x ≤ 30

Step-by-step explanation:

A university investigation was conducted to determine whether women and men complete medical school in significantly different a

Answer:

Following are the responses to the given question:

Step-by-step explanation:

$Null \ H_{yp}: \mu_{men} = \mu_{women}\\\\Alt \ Hyp: \mu_{men} \neq \mu_{women}\\\\Std\ Error\ (SE) = \sqrt{(\frac{s_1^2}{n_1}) + (\frac{s_2^2}{n_2})} \\\\$

$= \sqrt{(\frac{0.62}{90}) + (\frac{0.52}{100})} \\\\= 0.08$

$test\ statistic \ t = \frac{(x_1 - x_2)}{SE} = \frac{(8.4 - 8.5)}{0.08} = -1.25$

Degrees of freedom

$= \frac{(\frac{s_1^2}{n_1} + \frac{s_2^2}{n_2})^2}{\frac{(\frac{s_1^2}{n_1})^2}{(n_1 - 1)}} + \frac{(\frac{s_2^2}{n_2)^2}}{(n_2 - 1)} \\\\= 174$

Considering a degree of 5% importance

T for df critical value = 174 and sig level = 0.05 is +1.973

Let area of refusal shall be t < -1.973 or t > +1.973

Because statistical tests weren't in the refusal zone, they may not deny that zero but find that perhaps the argument how both women and men undergo med school is considerably different lengths of time is not significantly supported.
