Answer:

The expected number of keys she will try before she opens the door is 4.5.

Step-by-step explanation:

Probability of opening with the first key:

One key out of 8 working, so: 1/8 probability of opening with the first key, that is:

[tex]P(X = 1) = \frac{1}{8}[/tex]

Probability of opening with the second key:

Doesn't work on the first(7/8 probability), works on the second(1/7 probability). So

[tex]P(X = 2) = \frac{7}{8}*\frac{1}{7} = \frac{1}{8}[/tex]

Following the logic:

For each value of x from 1 to 8, we have that [tex]P(X = x) = \frac{1}{8}[/tex]

Find the expected number of keys she will try before she opens the door.

Each outcome multiplied by its probability. So

[tex]E(X) = 1\frac{1}{8} + 2\frac{1}{8} + 3\frac{1}{8} + 4\frac{1}{8} + 5\frac{1}{8} + 6\frac{1}{8} + 7\frac{1}{8} + 8\frac{1}{8} = \frac{1+2+3+4+5+6+7+8}{8} = 4.5[/tex]

The expected number of keys she will try before she opens the door is 4.5.

Answer:

Step-by-step explanation: 2(3p) = 2 x 3p = 6p

8p - 2p = 6p

Answer:

yes

Step-by-step explanation:

2(3p) = (2*3)p=6p

8p-2p = (8-2)p = 6p

So,  2(3p) is equivalent to 8p-2p

Answer:

6 mins

Step-by-step explanation:

Given that;

T(t) = Ce^-kt + T(s)

Since T(t) = 200◦F, and T(s) = 70◦F where t = 0

200= Ce^-k(0) + 70

C= 200 - 70

C = 130

Then when T(t) = 190◦F and t= 1s ;

190 = 130e^-(k *1) + 70

190 - 70 = 130e-^(k *1)

120/130 = e^k

0.923 =  e^-k

-k = ln(0.923)

k = 0.08

To determine the time taken to reach a temperature of  150◦F

150 = 130e^-(0.08t) + 70

150 - 70/130 = e^-(0.08t)

0.6154 = e^-(0.08t)

-(0.08t) = ln 0.6154

0.08t = 0.4855

t = 0.4855/0.08

t = 6 mins

Answer:

B: Gabriel's

Step-by-step explanation:

The range of the function is 0 ≤ y ≤ 8.

Option C is the correct answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

From the graph,

The y coordinate values are the range of the function.

Now,

We see that,

The y-coordinate is from 0 to 8.

So,

The range is 0 ≤ y ≤ 8

Thus,

The range is 0 ≤ y ≤ 8

Answer:

...

Step-by-step explanation:

7x - 2 +5x - 10 +4x = 180

16x - 12 = 180

16x = 168

x = 10.5

now plug it in

7(10.5) - 2 = 71.5°

4(10.5) = 42°

5(10.5) -10 = 42.5°

Answer:

72

Step-by-step explanation:

Volume of a triangular prism = L x B x H x 1 / 2

So in this case itd be

V = 2 x 9 x 8 x 1/2

V = 72 x 1/2

V = 36

Now it wants BOTH prisms and their congruent so

36 x 2 = 72

Answer:

The answer is C.

Explanation:

C is the answer because volume you multiply length times width times height. 9 times 2 time 8 = 144. When you use volume, it is always going to be to the 3rd power or cubed. Any way you say it.

Answer:

option C

Step-by-step explanation:

Given :-

And we need to tell which graph best matches the graph we drew. Firstly let's convert it into a quadratic equation by opening and simplifying the brackets.

[tex]:\implies[/tex] y = ( x + 2) ( x - 3)

[tex]:\implies[/tex] y = x ( x - 3)+2( x - 3)

[tex]:\implies[/tex] y = x² - 3x + 2x -6

[tex]:\implies[/tex] y = x² - x - 6

Now plot its graph. For that refer to attachment.

Answer:

The correct answer is A. The shape formed by the four chairs is a square.

Step-by-step explanation:

A square is a figure whose 4 sides are exactly equal in length, and whose 4 interior angles are equal to 90 degrees each. Thus, if the distance between the chairs is exactly the same between them, it is understood that the "sides" of the figure are all the same. Thus, if all the internal angles of the figure are 90º, the figure that the chairs form is a square.

Answer:

  W(x) = 27/256(x)(32-x)

Step-by-step explanation:

There are several ways you can do this. The method we've used here is to write a function that has zeros at x=0 and x=32, opens downward, and has a maximum at x=16 of 27.

The zeros give rise to the factored form ...

  w = x(x -32)

To make it open downward, we need to reflect this across the x-axis. We can add a leading minus sign, or we can swap the terms in the binomial that has a minus sign:

  w = -x(x -32) = x(32 -x)

This will have a value of 16(32 -16) = 256 at its peak. We want the peak to be 27, so we can vertically scale this function by a factor of 27/256. The grap attached shows this gives the desired result.

  W(x) = (27/256)(x)(32-x)

Answer:

1 second

Step-by-step explanation:

Using -b/2a I can get the maximum height of the ball. Assuming that there is no outside forces, there should be an equal time of going up and coming down, so if max height is at 1/2 seconds, then it should take 1 full second for the ball to hit the ground.

Answer:

A

Step-by-step explanation:

As the price goes up per dollar there is a definite decrease in sales. Specifically, about 5 shirts don't get sold per increase of one dollar.

The correct option is A. for every one dollar price increase of T- shirt, 5 fewer T-shirts were sold.

A scatter plot is a type of data visualization that shows the relationship between different variables. This data is shown by placing various data points between an x- and y-axis. Essentially, each of these data points looks “scattered” around the graph,

Given equation of line for that fits best for scattered data is y -5x + 80

From the graph it is clear that as the slope of the given equation is  decreasing one

y -5x + 80 =0

y ∝ -mx

(no. of T-shirts sold) ∝ (-5) × (price of a T-shirt)

So, as the price of the T-shirt increases the less T-shirt were sold.
