Can’t figure out the b but maybe using my diagram above it can help you solve B. Just make sure to remember that for B the base is a triangle

A stick is broken into two pieces, at a uniformly random break point. Find the CDF and average of the length of the longer piece

Oksanka [162]

Answer:

P(L ≤ l) =P (1-l ≤ U ≤ l)= l- ( 1 - l ) = 2 l - 1

Step-by-step explanation:

let assume that stick has length 1.Random variable L that make length of a longer piece and random variable U that mark point .See that L < l means that

U≤ l and 1-U ≤l

P(L ≤ l) =P (1-l ≤ U ≤ l)= l- ( 1 - l ) = 2 l - 1

this means 1-l≤U≤l

so we have

if we have L [1/2,1]

then apply the formula we have E(L)=3/4

Ron is five years older than twice his cousins Pat's age. The sum of their ages is less than 35. What is the minimum age Pat can

Akimi4 [234]

R = 2p + 5
r + p < 35

2p + 5 + p < 35
3p + 5 < 35
3p < 35 - 5
3p < 30
p < 30/3
p < 10.....Pat has to be less then 10

minimum age : 7
maximum age : 9

Algebra 1 3c-d=t solve for d

Oduvanchick [21]

First you need to get d alone. so subtract 13c from t and then flip the signs to make d positive so 13c-t=d

which property is illustrated by the following statement? 2(-3/9)=(-3/9)2^? Associative Property of Addition, Commutative Proper

Ratling [72]

Consider the given statement:

$2(\frac{-3}{9}) = (\frac{-3}{9})2$

We have to identify the property used in this statement.

1. Associative Property of Addition: Let a,b and c be three real numbers. This property states that $a+(b+c) = (a+b)+c$ . This property is not used in the given statement.

2. Commutative property of multiplication: Let 'a' and 'b' be two real numbers. This property states that $a \times b = b \times a$ .

In the given statement, $2(\frac{-3}{9}) = (\frac{-3}{9})2$

This statement holds commutative property of multiplication as whether 2 is multiplied to $\frac{-3}{9}$ or $\frac{-3}{9}$ is multiplied to 2, the result is same.

So, Commutative property of multiplication is illustrated in this statement.

3. Inverse property of multiplication: A number 'a' is said to have an inverse ' $\frac{1}{a}$ ' if $a \times \frac{1}{a}=1$ . This property is not used in the given statement.

4. Commutative property of addition: Let 'a' and 'b' be two real numbers. This property states that $a+b = b+a$ . This property is not used in the given statement.

The equation of the line of best fit for a scatter plot is yˆ=−14x+10 where x is age in years and y is average number of hours o

son4ous [18]

Hey there!

y = -1/4x + 10

Looking for the amount of hours of sleep for an 8 year old, so x is 8.

Solve for y:

y = -1/4(8) + 10

y = -2 + 10

y = 8

The predicted number of average hours of sleep for an 8 year old is 3. 8 hours.

Hope this helps!
