Consider this expression 5/6(1/2x+6)-3x<br> What is the value of the expression evaluated for x=12

just olya [345]

ANSWER

The correct answer is $-26$

EXPLANATION

The expression given to us is,

$\frac{5}{6}( \frac{1}{2}x+ 6)-3x$

We plug in $x=12$ . That means we substitute 12 wherever we see x to obtain,

$\frac{5}{6}( \frac{1}{2}\times 12+ 6)-3\times 12$

We simplify the parenthesis first to obtain,

$=\frac{5}{6}( 6+ 6)-36$

$=\frac{5}{6}( 12)-36$

$=5\times 2-36$

$=10-36$

$=-26$

Hence the expression evaluates to $=-26$

Paint is red : blue in a ratio of 2 : 4. If 5 litres of red is used how much blue is used

JulijaS [17]

so since the ratio of red paint to blue paint is 2:4 and you can simplify 2:4 into 1:2 and because 5 liters of paint is used you would have to multiply the 2 from the simplified ratio by 5 so you could get the answer 2*5 and that equals 10

For each of the following functions, (i) find the constant c so that f(x) is a pdf of a random variable X, (ii) find the cdf, F(

mel-nik [20]

Answer:

(a)

c=1/2

cdf is $F(x) = x^2$

Step-by-step explanation:

Remember that if $f$ is the pdf of a random variable X .

$\int\limits_{-\infty}^{\infty} f(x) \,dx = 1$

Then,

(a)

$\int\limits_{-\infty}^{\infty} 4xc \,dx = \int\limits_{0}^{1} 4xc \, d x = 2c = 1$

Therefore

c=1/2

and

$f(x)=2x$

then to compute the cdf, we have

$F(x) = P(X \leq x) = \int\limits_{-\infty}^{x} 2y \,dy = \int\limits_{0}^{x} 2y \, dy = x^2$
