Answer:

0.625

Step-by-step explanation:

We are told that the agent has 8 keycards.

We are also told that only one of the keycards can open each home.

Now, if the agent took 3 out of the 8 keycards with him, it means that;

Probability of opening by the keycards = ⅜

We are told that 40% or 0.4 of these homes were left unlocked.

This means that 60% or 0.6 are those that will require a key card.

Thus, probability of agent getting into a specific home is;

P(agent getting into a specific home) = 0.4 + 0.6(⅜)

P(agent getting into a specific home) = 0.4 + 0.6(0.375) = 0.625

Answer:

  D. P(-4,4) and S(-3,-2)

Step-by-step explanation:

The first coordinate is the number of units right of the vertical y-axis. Point P is 4 units left, so has an x-coordinate of -4. (Eliminates choices A and B)

The second coordinate is the number of units above the horizontal x-axis. Point P is 4 units up, so has a y-coordinate of +4. (Eliminates choice C)

The coordinates of points P and S are ...

  P(-4,4) and S(-3,-2) . . . . . matches choice D

Answer:the answer is  D. P(-4,4) and S(-3,-2)

Step-by-step explanation:took the test and got it right

Answer:

The procedure does results in a binomial distribution.

Step-by-step explanation:

For a binomial probability distribution to be applicable, certain conditions have to be met which are :

There must be a fixed number of observations ; here the number of observations are : 79

All observations must be independent ; the observations are independent ; odd or even

Observations must fall into one of two categories : success category or failure. Here, observations can be odd or even

The probability of success must be equally likely for each observation.

Hence, the procedure results in a binomial probability distribution.

Answer:

The first one cannot be simplified

reason: usually when simplifying an expression you combine like terms but in the given expression there are no like terms

An example of like terms would be 6a and 9a

Essentially what i am saying is that the variables have to be the same in order for them to be combined

The second one is 36r

This is the answer because they tried to combine like terms that aren't similar

r and f are not the same variable therefore they cannot be combined

Hope this helps :)

Given:

The quadratic equation is

[tex]y=3x^2-18x+15[/tex]

To find:

The x-coordinate and y-coordinate of the vertex.

Solution:

If a quadratic function is defined by [tex]f(x)=ax^2+bx+c[/tex], then the vertex is defined as:

[tex]Vertex=\left(\dfrac{-b}{2a},f(\dfrac{-b}{2a})\right)[/tex]

If [tex]a<0[/tex], then the function has a maximum at the vertex and ff [tex]a>0[/tex], then the function has a minimum at the vertex.

We have,

[tex]y=3x^2-18x+15[/tex]

Here, [tex]a=3,b=-18,c=15[/tex].

Since [tex]a=3>0[/tex], therefore the function has a minimum at the vertex. So, fill min in first blank.

Now,

[tex]\dfrac{-b}{2a}=\dfrac{-(-18)}{2(3)}[/tex]

[tex]\dfrac{-b}{2a}=\dfrac{18}{6}[/tex]

[tex]\dfrac{-b}{2a}=3[/tex]

Putting x=3 in the given function, we get

[tex]y=3(3)^2-18(3)+15[/tex]

[tex]y=27-54+15[/tex]

[tex]y=-12[/tex]

Therefore, the vertex is at point (3,-12).

Step-by-step explanation:

Answer:

x = 55

Step-by-step explanation:

First set the equations to equal eachother since theyre corresponding.

3x - 60 = x + 50

Then just solve for x.

3x - 60 = x + 50

     +60       +60

3x = x + 110

-x    -x

2x = 110

/2      /2

x = 55

Answer:

0.76 = 76% probability that a tourist visited at least one of these places

Step-by-step explanation:

I am going to solve this question using the probabilities as Venn sets.

We have that:

Event A: Tourist visited Beinjing.

Event B: Tourist visited Xi'an.

61 percent of the tourists to China visited the Forbidden City, the Temple of Heaven, the Great Wall, and other historical sites in or near Beijing.

This means that [tex]P(A) = 0.61[/tex]

33 percent visited Xi'an with its magnificent terracotta soldiers, horses, and chariots, which lay buried for over 2000 years.

This means that [tex]P(B) = 0.33[/tex]

18 percent of the tourists went to both Beijing and Xi'an.

This means that [tex]P(A \cap B) = 0.18[/tex]

What is the probability that a tourist visited at least one of these places?

This is

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

We already found these values. So

[tex]P(A \cup B) = 0.61 + 0.33 - 0.18 = 0.76[/tex]

0.76 = 76% probability that a tourist visited at least one of these places

Answer:

subtract 12 to form the identity (0) and cancel the 12.

Step-by-step explanation:

Subtract 12 from both sides.

8x=52−12

2 Simplify 52-1252−12 to 4040.

8x=40

3 Divide both sides by 88.

x=\frac{40}{8}

40/8

simplify 40 over 8 to 5

x=5

Answer:

×=5

Step-by-step explanation:

-12 both sides

then divide 8 both sides

40/8 =5

Answer:

-16 and 6

Step-by-step explanation:

If you went back on a graph from 5 eleven times you would get -16 and if you went forward on a graph you would land on 6. Gl human

Answer:

h(0)=10

h(4)=16

Step-by-step explanation:

for h(0) you would need to do the second equation because it is within the bounds of the variable.

h(0)= 2x^2 - 3x + 10

anything times 0 is 0

so 2(0)^2 - 3(0) + 10=

0-0+10=

10

h(4) would use the third equation since it's the only one that agrees with the variable 4

2^4=16
