Select all of the angles that are congruent to <5 plzzz helppp

kirill115 [55]

Answer:

Options A, D and F

Step-by-step explanation:

From the picture attached,

lines 'l' ad 'm' are the parallel lines and line 't' is a transversal intersecting each line at two different points.

From the angles formed at the points of intersection,

∠5 ≅ ∠8 [Vertical angles]

∠5 ≅ ∠4 [Alternate interior angles]

∠5 ≅ ∠1 [Corresponding angles]

Therefore, Options A, D and F will be the correct options.

Suppose that weights of bags of potato chips coming from a factory follow a normal distribution with mean 12.8 ounces and standa

MA_775_DIABLO [31]

Answer:

std dev = 0.625

Step-by-step explanation:

Given that weights of bags of potato chips coming from a factory follow a normal distribution with mean 12.8 ounces and standard deviation .6 ounces.

We must change std deviation such that

P(X<12) =0.01

Mean would remain the same as 12.8 oz

From normal distribution score we can find

10th percentile is -1.28\

i.e. we must have

$12.8-1.28*s = 12\\1.28s = 0.8\\s = 0.625$

Std deviation should be 0.625

(3xy/3x^2-12)*(x^2+3x+2/xy+y)

TiliK225 [7]

Value of expression $(3xy/3x^2-12)*(x^2+3x+2/xy+y)$ is $\frac{x}{x-2}$ .

<u>Step-by-step explanation:</u>

Here we need to evaluate expression : (3xy/3x^2-12)*(x^2+3x+2/xy+y) or ,

$(3xy/3x^2-12)*(x^2+3x+2/xy+y)$

Let's simplify this

⇒ $(\frac{3xy}{3x^2-12})(\frac{x^2+3x+2}{xy+y})$

Factorizing the terms we get:

⇒ $(\frac{3xy}{3(x^2-4)})(\frac{x^2+2x+x+2}{y(x+1)})$ { $a^2-b^2=(a+b)(a-b)$ }

⇒ $(\frac{xy}{(x-2)(x+2)})(\frac{x(x+2)+1(x+2)}{y(x+1)})$

⇒ $(\frac{xy}{(x-2)(x+2)})(\frac{(x+1)(x+2)}{y(x+1)})$

Cancelling similar terms we get:

⇒ $\frac{x}{x-2}$

Therefore , Value of expression $(3xy/3x^2-12)*(x^2+3x+2/xy+y)$ is $\frac{x}{x-2}$ .
