Answer:

The teacher should set the score 7 as the lowest passing grade.

Step-by-step explanation:

Let X = number of correct guesses.

All the questions are of true-false format.

The probability of getting a correct answer is, p = 0.50.

The total number of questions is, n = 10.

The random variable X follows a Binomial distribution with parameters n = 10 and p = 0.50.

The probability mass function of X is:

$P(X=x)={10\chose x}0.50^{x}(1-0.50)^{10-x};\ x=0,1,2,3...$

Now the teaches chose the grading scheme such that the probability of passing a student who guesses on every question is less than 0.05.

Then the probability of failing such a students is at least 1 - 0.05 = 0.95.

Compute the probability distribution of X.

Consider the probability distribution attached below.

The value of x for which P (X ≤ x) is at least 0.95 is, x = 7.

So the teacher should set the score 7 as the lowest passing grade.

The width of a rectangle is 4 inches greater than half the length. The perimeter is 56 inches. What is the length and the width

yulyashka [42]

Answer:

Length of the rectangle = 16 inches

Width of the rectangle = 12 inches

Step-by-step explanation:

Let the length of the rectangle be represented by x.

Then width can be expressed as $\[\frac{x}{2}+4\]
$

Perimeter of a rectangle is the sum of four sides of the rectangle.

This can be expressed as 2*(length + breadth)

= $2* (x + \frac{x}{2}+4)$

= $2* (\frac{3x}{2}+4)$

= $3x + 8$

But perimeter is given as 56.

So, $\[3x + 8 = 56\]
$

=> $3x = 48$

=> $x = 16$

Hence length of the rectangle = 16 inches

Width of the rectangle = $\frac{16}{2}+4$ = 12 inches

5x=15 y 2x=6 Son ecuaciones equivalentes? PORFAVOR AYÚDENME ES EMERGENCIA

mihalych1998 [28]

Si, los dos son iguales

Cuando haces 5x=15, la división dice que x = 3. Para 2x=6 puedes usar el resultado de x=3 de la problema de antes, y cuando te usas esto va a ver que 2 de x cuando x=3 es igual a 6, y por eso 5x=15 y 2x=6 son equivalentes.
