.A bag contains 3 red checkers and 5 black checkers. A checker is selected, kept out of the bag, and then another checker is selected. What is the P(black, then red)?

Answers

Answer 1

Answer: 15 / 56

Step-by-step explanation:

Number of red checkers = 3

Number of black checkers = 5

Total number of checkers = 8

P(black, then red) = 5/8 × 3/7 = 15/56

We should note that the probability to pick a black checker first will be 5 out of 8. Then, there'll be 7 checkers left and the probability to pick a res checker will be 3/7. We then multiply the probabality of each together.

Step-by-step explanation:

when x is 2 y = 0.

lets start with writing the function's equation;

it has a slope of 2 so 2x + k = y

given in the question when x = -3, y = -10

so k = -4

y = 2x - 4, 0 = 2x-4 then x = 2

On Monday the price of one share of Webb company stock was 24.85. By Friday the price was 25.004. By how much did the price change from Monday to Friday ?

Answers

Answer:

Change in price = 0.154

Step-by-step explanation:

Given that,

The price on Monday = 24.85

The price on Friday = 25.004

We need to find the change in price from Monday to Friday. It can be calculated as follows :

Change = 25.004 - 24.85

= 0.154

So, the required change in the price is equal to 0.154 .

Line H is represented by the following equation: 2x + 2y = 8

What is most likely the equation for line K so the set of equations has infinitely many solutions?

x + 2y = 2
x + y = 4
2x + y = 6
x − y = 8

Answers

Answer:

B

Step-by-step explanation:

Line H is represented by the equation:

[tex]2x+2y=8[/tex]

And we want to find Line K such that the set of equations has infinitely many solutions.

Remember the three solution sets for linear equations:

If the two are parallel, they have no solutions. If the two are not parallel, they will intersect and thus have only one solution. If the two are the exact same line, then they will have infinitely many solutions.

From Line H, we can divide both sides by two. This yields the equivalent equation:

[tex]x+y=4[/tex]

Therefore, the new equation and Line H are the same line. Thus, they will have infinitely many solutions.

The answer is B.

Answers

Answer:

d1 = 192

d2 = 192

Step-by-step explanation:

step 1

From the imformation given, the distance is the same

so from the table

d1 = 64t

d2 = 48(7-t)

the distance is the same, it means

d1 = d2

therefore we can get the time(t) from here

64t = 48(7-t)

64t = 336 - 48t

collect like terms

64t+48t = 336

112t = 336

t = 336/112

t = 3

substitute t into d1 to get the distance

d1 = 64t

d1 = 64 × 3

d1 = 192

Note, d1 = d2

d2 = 192 too

Daniel is baking a cake for Aaron's birthday. The recipe requires 2 1/2 cups of butter, 1/3 cups of brown sugar, and 1/2 cups of baking powder. What is the total amount of ingredients in cups if Daniel makes the cake twice as large as the recipe calls for?

Answers

Answer

4 6/12 or 2 3/4 cups of total ingredients

Step-by-step explanation:

There are 2 1/2 cups of butter, 1/3 cups of brown sugar, and 1/2 cups of baking powder.

You'd want to make the denominators the same numbers so it would be easier to divide.

So I multiplied 2 1/2 times 3, 1/3 times 2, and 1/2 times 3.

Then all the numbers would have a denominator of 6. Don't multiply the whole numbers or the numerators. Just the denominator.

''THE NUMBERS'' would change to 2 1/6, 1/6, and 1/6.

If I were to add that it would be 2 3/6.

BUT, You need to multiply by 2 after because it says in the question "How many ingredients in cups will Daniel make the cake twice as large".

What is 2 3/6 times 2 =  4 6/12 total.

If it says to simplify the answer. It would be "'2 3/4 total'' or both answers are correct

A shark is swimming 28 feet below sea level. If the angle of depression from a boat on the water is 19 degress. What is the distance between the boat and the shark?

Answers

Answer:

81.3 feet

Step-by-step explanation:

A shark is swimming 28 feet below sea level. If the angle of depression from a boat on the water is 19 degrees What is the distance between the boat and the shark?

We solve the above question using Trigonometric function of Tangent

tan θ = Opposite/Adjacent

θ = Angle of depression = 19°

Distance between the boat and the shark = Adjacent = ? = x

Opposite = 28 feet

Hence:

tan 19 = 28/x

Cross Multiply

tan 19 × x = 28

x = 28/tan 19

x = 81.317904575 feet

Approximately = 81.3 feet

The distance between the boat and the shark is 81.3 feet

A study is done on the population of a certain fish species in a lake. Suppose that the population size P(1) after years is given by the following exponential
function.
P(t) = 400(1.22)
Find the initial population size.
Does the function represent growth or decay?
O growth O decay
By what percent does the population size change each year?

Answers

Answer:

Growth22%

Step-by-step explanation:

Given function:

[tex]P(t) = 400(1.22)^{t}[/tex]

Initial population size is when t = 0

P(0) = 400(1.22)⁰ = 400(1) = 400

The multiple of 1.22 is applied every year, so the ratio of change is:

1.22 = 122% = 100% + 22%

This is an exponential growth which represents 22% annual growth.

The function is

y=400(1.22)^t

As per y=ab^x

1.22 is the rate of change

Its growth as it's greater than 1

The percentage increase is

1.22-10.2222%
