The correct option regarding Talia factoring is given by:

Talia needs to factor out a negative from one of the groups so the binomials will be the same.

<h3>Which expression is Talia tying to factor?</h3>

The expression is given by:

(15x² - 3x) + (-20x + 4).

Her first step was:

3x(5x - 1) + 4(-5x + 1)

After that, she did not factor out anything more out of the expression. However, looking at the two terms of the addition, we can realize that:

(-5x + 1) = -(5x - 1), hence she should factor out the negative.

Suppose X has a continuous uniform distribution over the interval [1.3, 6.2]. Round your answers to 3 decimal places.

goldenfox [79]

Answer:

(a) 3.75

(b) 2.00083

Step-by-step explanation:

It is provided that X has a continuous uniform distribution over the interval [1.3, 6.2].

(a)

Compute the mean of X as follows:

$\mu_{X}=\frac{a+b}{2}=\frac{1.3+6.2}{2}=3.75$

(b)

Compute the variance of X as follows:

$\sigm^{2}_{X}=\frac{(b-a)^{2}}{12}=\frac{(6.2-1.3)^{2}}{12}=2.00083$

(c)

Compute the value of P(X < 3.7) as follows:

$P(X < 3.7)=\int\limits^{3.7}_{1.3}{\frac{1}{6.2-1.3}}\, dx\\\\=\frac{1}{4.9}\times [x]^{3.7}_{1.3}\\\\=\frac{3.7-1.3}{4.9}\\\\\approx 0.4898$

Thus, the value of P(X < 3.7) is 0.4898.

Lucy, Sam, and Bob served a total of 72 orders Monday at the school cafeteria. Bob served 3 times as many orders as Lucy. Lucy s

julia-pushkina [17]

let

x-------> the number of Lucy's orders

y-------> the number of Sam's orders

z-------> the number of Bob's orders

we know that

<u> $x+y+z=72$ </u>----> equation A

$z=3x$ -----> equation B

$x=8+y-----> y=x-8$ -----> equation C

substitute equation B and C in equation A

$x+(x-8)+3x=72\\ 5x=72+8\\ 5x=80\\x=16\\$

find z

$z=3*16=48$

find y

$y=x-8------> y=16-8=8$

therefore

<u>the answer is</u>

the number of Lucy's orders is $16$

the number of Sam's orders is $8$

the number of Bob's orders is $48$
