Answer:

60/220

Step-by-step explanation:

we use combination,

$(\frac{5}{1} ) \times ( \frac{4}{1} ) \times ( \frac{3}{1} )$

$5 \times 4 \times 3 = 60$

then, all divided by,

$(\frac{12}{3}) = 220$

$60 \div 220$

What value for c will make the expression a perfect square trinomial? x2 – 7x + c negative StartFraction 49 Over 4 EndFraction n

puteri [66]

Answer: $c=\frac{49}{4}$

Step-by-step explanation:

You can find the value of "c" that will make it a perfect square trinomial by Completing the square.

Given the following expression provided in the exercise:

$x^2 - 7x + c$

You can notice that it is written in this form:

$ax^2-bx+c$

Then, you can identify that the coefficient "b" is:

$b=-7$

Since to complete the square you must add and subtract the half of square of coefficient "b", you can conclude that:

$c=(\frac{b}{2})^2$

Therefore, substituting "b" into $c=(\frac{b}{2})^2$ , you get:

$c=(\frac{-7}{2})^2\\\\c=\frac{49}{4}$

The heights of students in a class are normally distributed with mean 55 inches and standard deviation 5 inches. Use the Empiric

maks197457 [2]

Answer: c)[50,60]

Step-by-step explanation:

The Empirical rule says that , About 68% of the population lies with the one standard deviation from the mean (For normally distribution).

We are given that , The heights of students in a class are normally distributed with mean 55 inches and standard deviation 5 inches.

Then by Empirical rule, about 68% of the heights of students lies between one standard deviation from mean.

i.e. about 68% of the heights of students lies between $\text{Mean}\pm\text{Standard deviation}$

i.e. about 68% of the heights of students lies between $55\pm5$

Here, $55\pm5=(55-5, 55+5)=(50,60)$

i.e. The required interval that contains the middle 68% of the heights. = [50,60]

Hence, the correct answer is c) (50,60)
