PLEASE HELP WITH THIS CONDITIONAL PROBABILITY QUESTION AND PLEAS COULD YOU SHOW A STEP BY STEP EXPLANATION.

Adam and Boris regularly play each other at chess and in 60% of their games each player is subject to ta time limit but only 30% of the games played without a time limit.

(a) Find the probability that Adam wins his next game of chess against Boris

(b) Given that Adam wins a game, find the probability that it was played with a time limit.

Answer: 3 seconds

Step-by-step explanation:

Hi, the correct equation is d (t) = 144- 16 t²

So, to answer this question we have to analyze the information given:

When the car reaches the ground the distance, d (t) of the car from the ground is 0.

0 = 144- 16 t²

Solving for t:

16 t² =144

t²=144/16

t²= 9

t = √9

t = 3 seconds  

Feel free to ask for more if needed or if you did not understand something.  

Answer:

C

Step-by-step explanation:

t>3

Answer:

140

Step-by-step explanation:

Angle 4 is congruent to angle 2 by corresponding angles postulate.  Therefore, angle 2 is also 40.  Angle 2 and angle 3 are supplementary, or add up to 180 because they are on a straight line.  140 and 40 add up to 180 so angle 3=140 degrees

Answer:

Personally, the steepest ladder I would be willing to climb would be a ladder with 2 meters long, that's it, because I don't like hights.

On the other hand, the shallowest ladder would be the nearest to the ground level possible, because, as I said before, I don't like being to far away from ground level.

Question:

Find the area of the shaded segment. Round your answer to the nearest square centimeter.

a) 24 cm²

b) 23 cm²

c) 21 cm²

d) 22 cm²

Answer:

d) 22 cm²

Step-by-step explanation:

We have Area and a Triangle in that diagram.

In other to find the shades segment , we have to find the Area of the triangle and the Area of the sector

Step 1

Area of a Triangle

= 1/2 × a × b × sin θ

Where θ = 120°

a = 6 cm

b = 6 cm

Area of the triangle = 1/2 × 6 × 6 × sin 120°

= 15.59 cm²

Step 2

Area of the sector

The formula is given as

Area = πr²θ/360

r = radius = 6cm

Area = π × 6² × 120/ 360

Area = 37.699111843cm²

Approximately = 37.70 cm²

Step 3

The Area of the shaded segment = Area of the sector - Area of the triangle

= 37.70cm² - 15.59cm²

= 22.11 cm²

Approximately to the nearest square centimeter

= 22 cm²

Answer:

1 hour

Step-by-step explanation:

Let's assume that Patrick is travelling on a straight line throughout the whole path in order to minimize the distance.

The number of miles that he can travel on a full tank is:

[tex]m = 5\ mpg*4\ gallons\\m=20\ miles[/tex]

The distance travelled by Patrick in one hour (from 2p.m. to 3p.m.) is:

[tex]d^2=6^2+8^2\\d=\sqrt{100}\\ d=10\ miles[/tex]

If he is travelling at 10 miles per hour, and he could travel for a total of 20 miles, then the time remaining before the tank runs out of gasoline is:

[tex]t=\frac{20-10}{10}\\ t=1\ h[/tex]

If he continues at this rate, the gas will last for 1 more hour.

The name of the savings account that offers higher interest rates, but in which a person's money must stay deposited for a specific amount of time is B. CD.

Money market account, Certificates of deposits (CD) and the regular savings account are all different types of savings account.

Regular savings account has only lower interest rate while both CD and Money market account have higher interest rates.

And the money must be stayed in the account for a fixed period of time in CD accounts. This is not required in the money market accounts.

Thus, CD is the correct answer.

Answer: The height of the model on the right is 22.5 cm .

Step-by-step explanation:

We can see that , the given different models of the same triangular-shaped garden are similar.

For the first model 1 cm = 3.75 m

whereas for the second model 1 cm = 2.5 m

Now , the constant rate of proportion for this (k) = [tex]\dfrac{3.75}{2.5}=\dfrac{375}{250}=1.5[/tex]

Now , if height of the model on the left is 15 cm , then the height of the model on right = 15 x k

= 15 x 1.5

= 22.5 cm

Hence, the height of the model on the right is 22.5 cm .

Answer:

Answer: A  y= -4x + 2

Step-by-step explanation:

y= mx + b

going from x=0 to x=1, the y coordinate moves down 4, so the slope would be -4

Answer:

To convert from a decimal to percent, multiply a decimal by 100 and add the percent sign.

Example: 0.10 becomes 0.10 x 100 = 10%

Example: 0.22 becomes 0.22 x 100 = 22%

To convert from a percent to a decimal, divide a percent by 100 and remove the percent sign.

Example: 10% becomes 10/100 = 0.10

Example: 22% becomes 22/100 = 0.22

Answer:

12p - 7q - 4

Step-by-step explanation:

In the absence of instructions here, I can only assume that you want to simplify this expression.

4p + 8p - 32 - 7q + 28  =  12p - 7q - 4

Answer:

2

Step-by-step explanation:

14x + 2 = 30

14x = 28

x = 2

Answer:

x =2

Step-by-step explanation:

9x + 2+ 5x = 23 +7

Combine like terms

14x +2 = 30

Subtract 2 from each side

14x +2-2 = 30-2

14x = 28

Divide each side by 14

14x/14 = 28/14

x = 2

Answer:

F(y^2) = 1/ (y^2-3)

Step-by-step explanation:

F(x) = 1/ (x-3)

Replace x with y^2

F(y^2) = 1/ (y^2-3)

Answer: f(y^2) = 1/((1/(x-3))^2-3)

Step-by-step explanation:

To start to understand this equation realize y = f(x) but f(x) gives a little bit more information specifically to define x as whatever is in the parenthesis of f(_).

For example f(x) = x/2

so lets say x = 2

so "f(2) = 2/2" or "y = 1 when x = 2"

In this equation y or f(x) = 1/(x-3)

so to get f(y^2) = 1/(x-3)

square the value of y and plug it into 1/(x-3) as the value of x

f(y^2) = 1/(y^2-3)

Answer:

She made 40% of her shots.

Step-by-step explanation:

First, you would subtract 10 - 6 = 4.

Second, you would make 4/10 a decimal to convert it to a percent by moving the decimal point to places to the right = .40 = 40%.

Your answer is 40% of her shots were made.

Beth made 40 percentage of  shots.

Percentage is a part of the whole number. It is denoted by % sign.

1 %= 1/100.

The total number of shots taken by Beth = 10

The missed shots by Beth= 6

The Shots which are made by Beth = 10-6 =4

The percentage of shots that Beth make,

= 4/10×100

=40%

Step-by-step explanation:

Answer:

y= (2/3)x - 4

Step-by-step explanation:

To answer this you'll want to use the slope intercept form of a line:

y= mx + b

So to solve essentially you just have to find the values for m and b

- m represents the slope of the line

- b is the y-intercept (the point where the line crosses the y-axis)

You can figure that b = -4 because the line will cross the y-axis when x = 0, and you are given the point on the line (0,-4), where x is equal to 0.

Now to find the slope of the line, since you are given two points on the line you will want to use the slope equation:

slope = [tex]\frac{y1-y2}{x1-x2}[/tex]

So you can assign each of the two points a number (1 or 2) where its values are equal to (x1, y1) or (x2, y2). It does not matter which point gets which number.

In this example:

We will assign the point (6,0) to be (x1, y1),

and we will assign the point (0, -4) to be (x2, y2)

So we end up with the following:

m= [tex]\frac{0- (-4)}{6-0}[/tex]

m=  [tex]\frac{0+4}{6}[/tex]

m=  [tex]\frac{4}{6}[/tex]

Simplify the fraction:

m = [tex]\frac{2}{3}[/tex]

From there you just substitute in for m and b into the slope intercept equation

Answer:

On the second step there is a mistake. You have to multiply 2 times 2 before you add the five

Answer:

See below;

Step-by-step explanation:

We are given the following;

5 + [ 2 * 2 + 5 ], ⇒ add 2 and 5

5 + [ 2 *  7 ], ⇒ multiply 2 by 7

5 + 14, ⇒ combine like terms

Solution; 19

Now as we can see from the first ⇒ second step the process as to simplify the expression 5 + [ 2 * 2 + 5 ] further, was by adding 2 and 5. Of course by PEDMAS, it would be that multiplication takes place before that of addition, so that it should have been that 2 was multiplied by 2 first!

Solution below;

Answer:

7.1 m

Step-by-step explanation:

A cube has 6 congruent square faces.

Given the surface area = 302.46 m² then the area of one face is

302.46 ÷ 6 = 50.41 m²

The area of a square = s² ( s is the side length ), thus

s² = 50.41 ( take the square root of both sides )

s = [tex]\sqrt{50.41}[/tex] = 7.1 m

The length of each side of the cube is 7.1 m
