Answer: a=1

Step-by-step explanation:

-8(a-4)+3a=2(4a+9)+1 given

-8a+32+3a=8a+18+1 distribute

+8a +8a

32+3a=16a+18+1 subtraction property of equality

-3a -3a

32=13a+18+1 addition property of equality

32=13a+19 add like terms

-19 -19

13=13a addition property of equality

÷13 ÷13

1=a multiplication property of equality

a=1 is the answer. Hope this helps!

If x has a continuous uniform distribution on the interval (0,5), what is the 25th percentile for x?

Natasha_Volkova [10]

Given that $X\sim\mathrm{Unif}(0,5)$ , it has PDF

$f_X(x)=\begin{cases}\dfrac15&\text{for }0\le x\l5\\\\0&\text{otherwise}\end{cases}$

and thus CDF

$F_X(x)=\mathbb P(X\le x)=\begin{cases}0&\text{for }x$

The 25th percentile is the value $X=k$ such that $\mathbb P(X\le k)=0.25$ . We have

$\mathbb P(X\le k)=\dfrac k5=0.25\implies k=1.25$

I added three non-unit fractions together to make a whole. What three fractions could that be?

Anna11 [10]

Answer:

For example $\frac{2}{6}$

Step-by-step explanation:

A non-unit fraction is a fraction of which the numerator is not equal to one. Additionally, the question does not state to pick three different ones and thus you can pick any fraction that when multiplied by three (since you take three fractions together) add up to a whole number (I'm picking the whole number to be one here just to make it simple), where the numerator is not equal to one of course.

For example: $\frac{2}{6}$ , because 3· $\frac{2}{6}$ = $\frac{6}{6}$ = 1

Infinitely many solutions can be found: for example $\frac{3}{9} , \frac{4}{12} , etc$
