andre [41]

Answer: f(x) has a domain that contains the domain of g(x).

Step-by-step explanation:

The domain of f(x) is: x - 2 > 0

--> x > 2

The domain of the graph g(x) is: x ≥ 3

All of the values of x ≥ 3 are included in x > 2.

Which expression is equivalent to 7(p+2n)+n?

Illusion [34]

We actually need the choices but oh well, we can simpify and hopefuly it is one of the choices

remember the distributive property
a(b+c)=ab+ac
so

7(p+2n)+n
distribute first
7(p)+7(2n)+n
7p+14n+n
7p+15n is an equivilent expression

Triangle DEF is shown below.

just olya [345]

Answer:

A triangle similar to DEF will have an angle that measures 45 degrees, an angle that measures 65 degrees, and an angle that measures 70 degrees

Step-by-step explanation:

Given

See attachment for complete question

Required

Angles of a triangle similar to $\triangle DE F$

First, calculate the angle at D

$D + 110^o = 180^o$ ---- angle on a straight line

Collect like terms

$D = 180^o - 110^o$

$D = 70^o$

Next, calculate the angle at F

$F + 135^o = 180^o$ ---- angle on a straight line

Collect like terms

$F = 180^o -135^o$

$F = 45^o$

Lastly, the angle at E

$D + E + F = 180^o$ --- angles in a triangle

Make E the subject

$E = 180^o - D - F$

$E = 180^o - 70^o - 45^o$

$E = 65^o$

A triangle similar to $\triangle DE F$ will have 45, 70 and 65 degrees as its angles

Suppose a jar contains 10 red marbles and 34 blue marbles. If you reach in the jar and pull out 2 marbles at random at the same

denpristay [2]

Answer:

The probability that both are red is $P(red\:and \:red)=\frac{45}{946}\approx0.04756\approx4.756\%$ .

Step-by-step explanation:

Probability is simply how likely something is to happen and its given by

Probability of an event = (# of ways it can happen) / (total number of outcomes)

Two events are dependent when the outcome of the first event influences the outcome of the second event. The probability of two dependent events is the product of the probability of X and the probability of Y AFTER X occurs.

$P(A\:and\: B)=P(A)\cdot P(A|B)$

At our first pull, there is an $P(red)=\frac{10}{10+34}$ chance that a red will be pulled.

At the second pull there is a $P(red)=\frac{9}{9+34}$ chance that the second marble will be red.

Therefore, the probability that both are red is

$P(red\:and \:red)=\frac{10}{10+34}\cdot \frac{9}{9+34}=\frac{45}{946}\approx0.04756\approx4.756\%$
