Here,
A jar consists of 4 red marbles, 5 yellow marbles, 3 green marbles, and 3 blue marbles.
Total number of marbles = 15

1) probability that the outcome contains green and/or blue marbles only,
= 2 / 6 = 1 / 3

2.)  probability that the outcome contains only green marbles,
= 3 / 15 = 1 / 5

3.) the probability that the outcome contains no green marbles,
  = 3 / 12 = 1 / 4

Step-by-step explanation:

take 3.7 and divide it by 4 to get 0.925

then apply 0.925% to x 4 times to find out the compounded rate

Step-by-step explanation:

cross multiply both sides

2(6x+1)=3(5x–2)

12x+2=15x–6

collect like terms

+2+6=15x–12x

8=3x

divide both sides by 3

Answer:

Per acre will cost 6200

70 acres will cost 434,000

Step-by-step explanation:

you’re buying 60 acres Of farmland at a cost of 372000

1) What is the cost per acre

In order to find the cost per acre we divide the values which is;

➟ 372000 ÷ 60

➟ 6200

∴ it will cost 6200 per acre

2) What would be the cost for 70 acres

to find how much it will cost for 70 acres we will multiply the value per acre by 70 which is;

➟ 6200 × 70

➟ 434,000

∴ it will cost 434,000 for 70 acres

The yield on the corporate bond of a face value of $1000 is 7.77%.

What is the percentage discount?

The percentage discount is the discount given on a product as compared to the given discount on 100 rupees.

Given, the face value of the bond is $1000.

Discounted price of the bond is $900.

Therefore, the fixed interest on the bond for that period will be

= $1000 × 7/100 = $70.

Now, the yield on that corporate  bond = 70 × 100/900 % = 7.77% .

Hence, the yield on the corporate bond of a face value of $1000 is 7.77%.

Answer:

$3:00

Step-by-step explanation:

let 'x' be the money that the parents gave to Jane and her sister each

Jane will have 7+x dollars

Jane's sister will have 2 + x dollars

Jane had twice as much money as her sister thus

7 + x = 2(2 + x)

7 + x = 4 + 2x

4 + 2x = 7 + x

2x - x = 7 - 4

x = $3

the parents gave $3 to each.

The width of the rectangle = 15 yd

The length of the rectangle = 60 yd.

Perimeter of a rectangle = 2(length + width).

Given the following:

Width of the rectangle = w

Length of the rectangle = 4w

Perimeter of the rectangle = 150 yd.

Therefore:

2(4w + w) = 150

2(5w) = 150

10w = 150

10w/10 = 150/10

w = 15

Width of the rectangle = w = 15 yd

Length of the rectangle = 4w = 4(15) = 60 yd.

There are 11 scores, (N)  in the population.

The given parameters are:

Variance, s^2 = 5

Sum of squares, SS = 50

The variance of the population is calculated using

s^2 = SS/[N - 1]

So, we have

5 = 50/[N - 1}

Cross multiply

So, we have

5(N - 1) = 50

This gives

N - 1 = 10

Add 1 to both sides

N = 11

Using z-scores, it is found that due to the higher z-score, Luna did better on the exam.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

From the two bullet points, it is found that the student who did "better" is the one whose grade has the higher z-score.

For Hazel, the parameters are given as follows:

[tex]X = 93, \mu = 80, \sigma = 8[/tex]

Hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (93 - 80)/8

Z = 1.625.

For Luna, the parameters are given as follows:

[tex]\mu = 68, X = 40, \sigma = 15[/tex]

Hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (68 - 40)/15

Z = 1.87.

Due to the higher z-score, Luna did better on the exam.

Answer:

20, 21,22,23

Step-by-step explanation:

Consecutive means in order.  Integers are the set of whole numbers and their opposites: ...-3,-2,-1,0 ,1,2,3...

Let x = the one sibling

Let x + 1 = the second sibling

Let x + 2 = the third sibling

Let x+4 = the fourth sibling.

If you add the four siblings together they equal 86

(x) + (x +1) + (x + 2) + (x+3) = 86  I put the parentheses in so that you can see each sibling, but it is not needed.

x + x+ 1 +x + 2 + x+ 3 = 86  Combine like terms

4x + 6 = 86  Subtract 6 from both sides

4x = 80  Divide both sides by 4

x = 20

The first sibling is 20, then 21, then 22 and finally 23

Check:

20 + 21 + 22 + 23 = 86

The domain of the function is all the real numbers and the range is from -2 to 2.

The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x).

A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

In the image, we can see that the value of the function varies from -2 to 2 at all the possible values of the real numbers.

Answer:

B. The airplane starts its descent from an altitude 500 feet higher

Step-by-step explanation:

f(x) = −300x + 30,000

the function itself represents the airplane's altitude. the y intercept, 30,000 ft, then represents the initial starting position of the plane.

when it changes

g(x) = −300x + 30,500

only the y intercept changes. it's now 30,500 ft, which is 500 more than before. that means the plane initial position is 500 feet higher.

since the term with x doesn't change, the rate will not be affected. the answers with slower or faster talks about rate, which isn't what changed.

Answer:

97

Step-by-step explanation:

To find x² + y², use the identity (x - y)² = x² + y² - 2xy.

(x - y)² = x² + y² - 2xy

Substitute xy = 36 and x - y = 5 in the above formula,

   5²    =  x² + y² - 2*36

 25     = x² + y² - 72

Add 72 to both sides,

25 + 72 = x² + y²

x² + y² = 97

(y - 8)=(-1/5)(x+ 10).

As given,

Given points of linear equation: (-10,8), (-5, 7) , (10,4), (15,3)

Consider (x₁, y₁)=(-10,8) and (x₂ ,y₂)=(-5,7)

Slope 'm'=(y₂-y₁)/(x₂-x₁)

From the graph of the fifth root function, we have that:

In a graph:

Hence, since the given graph has no holes, and keeps going to infinity, we have that both the domain and the range are all real values.

Since the function has no holes, it is also continuous, and has no vertical asymptotes.

For this problem, we have that the function is moving right and up over it's entire domain, hence it is increasing for all real values, and never decreasing nor constant.

Since the graph passes through the origin, we have that:

For this problem, looking at the graph, we have the the second statement holds true for all values of x, hence the function is odd.

It is given by the values of y when x -> ∞.

Hence:

For the end behavior, y -> - ∞ when x -> -∞ and y -> +∞ when x -> +∞.

Since f(x) -> ∞ when x -> ∞, the function has no asymptotes.
