Answer:

times 2075 by .30 and that's your answer

The total retail cost of all the jewelry is $2697.5

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

Maybell just purchased $2075 worth of jewelry.

Now, marks up her cost by 30% then

= 2075 x 30/100

= 622.5

Thus, the total retail cost of all the jewelry

= 2075+ 622.5

= $2697.5

Answer:

packages of buns = 1,260

packages of patties = 840

Jars of pickles = 1,680

Step-by-step explanation:

packages of buns = 3

packages of patties = 2

Jars of pickles = 4

Number of people = 420

Each person of the 420 people gets packages of buns, packages of patties, and jars of pickles in the ratio 3:2:4

packages of buns needed for 420 people = 3 × 420

= 1,260

packages of patties needed for 420 people = 2 × 420

= 840

Jars of pickles needed for 420 people = 4 × 420

= 1,680

packages of buns = 1,260

packages of patties = 840

Jars of pickles = 1,680

To feed at least 420 people minimum number of packages of buns, packages of patties, and jars of pickles needed is 1,260, 840, 1,680 respectively.

Answer:

02383923892

Step-by-step explanation:

The coordinates values of the point is (- 17, 0).

An ordered pair is made up of the ordinate and the abscissa of the x coordinate, with two values given in parenthesis in a certain sequence.

Pair in Order = (x, y)

x is the abscissa, the distance measure of a point from the primary axis x

y is the ordinate, the distance measure of a point from the secondary axis y

Given, The point is on the x-axis and 17 units to the left of the y-axis.

Now, the value of y at the y-axis is 0 and the point is 17 units left to it so it should be - 17.

So, the coordinate points are (- 17, 0).

Answer:

Expected value = 190

Variance = 4000

Step-by-step explanation:

Let X be the number of the trials until the third success of the bad pump.

This implies that X is a negative binomial distribution having θ = 20% = 0.2.

Now, if for example it will take X trials to use up the three pumps, then the total time is 10 min/trials + extra 10 minutes for the 3 bad pumps

This means the total time is written as;

T = 10X + (10 + 10 + 20)

T = 10X + 40

Mean which is also expected value of X is;

μ_x = 3/0.2 = 15

Variance of X is; σ²_x = 40

Thus;

Mean of T will be;

μ_T = 10μ_x + 40

μ_T = 10(15) + 40

μ_T = 190

Also, variance of T will be;

σ²_T = 10²•σ²_x

σ²_T = 100 × 40

σ²_T = 4000

Your function is a constant and given the instructions of rounding it seems likely that you have a typo in your question. Anyway here goes the answer.

Since the function is constant no matter the input x the output is always equal to 0.2% because 0.2% is the only value defined in the range of the function.

Answer:

0.58 = 58% probability she passes both courses

Step-by-step explanation:

We can solve this question treating the probabilities as a Venn set.

I am going to say that:

Event A: She passes the first course.

Event B: She passes the second course.

The probability she passes the first course is 0.67.

This means that [tex]P(A) = 0.67[/tex]

The probability she passes the second course is 0.7.

This means that [tex]P(B) = 0.7[/tex]

The probability she passes at least one of the courses is 0.79.

This means that [tex]P(A \cup B) = 0.79[/tex]

a. What is the probability she passes both courses

This is [tex]P(A \cap B)[/tex].

We use the following relation:

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

So

[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B) = 0.67 + 0.7 - 0.79 = 0.58[/tex]

0.58 = 58% probability she passes both courses

1400.6

Step-by-step explanation:

7003 divided into 5 groups puts 1400.6 in each group

Answer:

1400.8

Step-by-step explanation:

5/7003

1. 7-5 (5 goes in once)

2. you can't do 2-5 so drop down the 0. (20)

3. 5 goes into 20 4 times. add the 4 to the top

4. put the zero in since it doesn't go with anything (it should look like 1400)

5. drop the 3 down but since 5 can't go in add a zero (and a decimal to your answer on top) - 1400.

6. 5 goes into 30, 8 times.

7. final answer: 1400.8
