Answer:

$48

Step-by-step explanation:

first you have to divide 18 by three to see how much one costs then multiply that number by 16. that number was 3.

The cost of 16 planters is $48.

Given that, Kelly purchased 6 planters for a total of $18. She wants to purchase another 16 planters at the same unit price.

We need to find how much will 16 planters cost.

Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. The proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

Now, let the cost of 16 planters be x.

Then, the proportion is 6:18::16:x

Product of means=18×16

Product of extremes=6×x

So, Product of means=Product of extremes

18×16=6×x

⇒x=288/6

⇒x=48

Therefore, the cost of 16 planters is $48.

Answer:

We have the system of equations:

y = -2*x

y = 2*x + 4.

To solve it by graphing, you need to graph both lines and see in which point the lines intersect each other.

You can see it in the image below. (blue is y = 2*x + 4, and green is y = -2*x)

We also can calculate the solution with math, let's do that:

y = -2*x

y = 2*x + 4.

We can replace the first equation in the second one, to get:

-2*x = 2*x + 4

Now let's solve this for x

-2*x -2*x = 4

-4*x = 4

x = 4/-4 = -1

Evaluating this in one of the equations we get:

y = -2*-1 = 2

Then the solution is the point (-1, 2), exactly what we can see in the graph.

Step-by-step explanation:

Given that:

Number of Large Marbles = 14

Number of Small Marbles = 11

Number of Green large marbles = 8

Number of White small marbles = 5

We can now find the number of white large marbles and green small marbles from the information stated above.

No of white large marble = total large marble minus green large marble

= 14-8

= 6

No of green small marbles = Total small marbles minus white small marble.

= 11-5

= 6

Let the following be represented

( X,Y, Z,Q ) as follows:

Let Y be the event of drawing small marble

Let X be the event of drawing large marble

Let Q be the event of drawing white marble

Let Z be the event of drawing green marble.

Since, only one marble is drawn at a time we calculate,

P( X ) = 14/25

P( Y) = 11/25

P(Z) = 14/25

P( Q) = 11/25

P(Y∪Q)=P(Y)+P(Z)−P(Y∩Z)...(1)

We need to find the value of

P(Y∩Z)

In 11 small marbles there are 6 green marbles so the value of P(Y∩Z) is given by P(Y∩Z)=6/11

Therefore, substitute the values in equation 1.

P(Y∪Z)=P(Y)+P(Z)−P(Y∩Z)=11/25+14/25-

6/11

=0.44+0.56−0.5455

= 1-0.5455

= 909/2000

= 0.4545

Then, one can conclude that the probability of drawing a small or green marble is 0.4545

Answer:

Step-by-step explanation:

The chance/probability of 10-year-old passenger cars passing an emission test is 80%.

200 10-year-old passenger cars will be tested next week.

How many of the 200 cars are expected to pass the emission test?

If there is an 80% chance of them passing the test then it means that 80% of the cars pass the test at any given time.

80% of 200 = 0.8 × 200 = 160

Hence, 160 (of the 200) cars are expected to pass the test.

Step-by-step explanation:

In Mathematics, the sieve of Eratosthenes is an ancient algorithm for finding all prime numbers up to any given limit. It does so by iteratively marking as composite (i.e., not prime) the multiples of each prime, starting with the first prime number, 2. The multiples of a given prime are generated as a sequence of numbers starting from that prime, with constant difference between them that is equal to that prime.This is the sieve's key distinction from using trial division to sequentially test each candidate number for divisibility by each prime.

In the case of Jonas and his washing machine the independent variables are:

The dependent variables are:

The independent variable refers to all those variables that are tested experimentally, being manipulated by researchers in order to test a hypothesis.

Generally, the independent variable has the greatest influence on the result of the experiment, this means that it modifies all the dependent variables.

The independent variable refers to the qualities or characteristics whose behavior is affected by the independent variable. It is about the variable or variables that are measured in order to be able to interpret the results and confirm or discard a hypothesis.

According to the above, it can be inferred that the independent variables in the case of Jonas are the type of washing machine because this variable will directly affect the other variables.

For example, depending on the type of washing machine Jonas uses, it will consume different amounts of energy and will need different amounts of water.

Answer: La probabilidad es 0.24

Step-by-step explanation:

De 240 personas, sabemos que 100 tienen una vista izquierdista.

Entonces la probabilidad de que una persona, seleccionada al azar, tenga una vista política izquierdista es:

Pa = 100/240 = 5/12

Entonces la probabilidad de que una persona elegida al azar NO tena una vista política izquierdista, es:

Pb = 1 - Pa = 1 - 5/12 = 7/12.

Queremos calcular la probabilidad que de 5 personas elegidas al azar, solo una tenga una vista izquierdista.

Entonces vamos a tener Pa una vez, y Pb 4 veces.

Y como sabemos, la probabilidad conjunta es igual al producto de las probabilidades, entonces:

p = Pa*Pb^4 = (5/12)*(7/12)^4

Pero esto va a ser para un solo arreglo (por ejemplo, de las 5 personas electas, la primera tiene una visión izquierdista), entonces tenemos que tener en cuenta las permutaciones, que van a ser las posibles permutaciones de un elemento en un espacio de 5 posibles espacios.

Son 5 permutaciones, y estas son:

La primera tiene visión izquierdista.

La segunda tiene visión izquierdista.

La tercera tiene visión izquierdista.

La cuarta tiene visión izquierdista.

La quinta tiene visión izquierdista.

Que también es igual a la combinatoria de 5 en 1.

[tex]C(5,1) = \frac{5!}{(5 - 1)!*1!} = 5[/tex]

Entonces la probabilidad que buscamos va a ser:

P = 5*p = 5*(5/12)*(7/12)^4 = 0.24

Find sketch of parallelogram attached

Answer and explanation:

A parallelogram is a quadrilateral which is wider than it is long. A parallelogram has two sides parallel to the other. From the above, we are told the parallelogram PQRS has an angle QPS 120, with sides 10cm and 8cm, we use this to sketch the parallelogram

We find that angle QPS is 120 degrees hence angle RSP is 60 degrees since angle on straight line is 60 degrees from 180-120 in angle QPS and alternate angles are equal. Also opposite angles of a parallelogram are equal

Answer:

The brand name television's dimensions are 32 inches by 64 inches.

Step-by-step explanation:

Scaling

Jason is considering two similar televisions at a local store. The sizes of the generic television are 3/8 the size of the brand name.

If we knew the size of the brand name television, we would have to multiply its dimensions by 3/8, but instead, we have the dimensions of the generic television, so to find the brand name television, we multiply by 8/3.

12 inches * 8/3 = 32 inches

24 inches* 8/3 = 64 inches

The brand name television's dimensions are 32 inches by 64 inches.

Answer:

The brand name television's dimensions are 32 inches by 64 inches.

1/5 of your money is = 30

Step-by-step explanation:

2/5 of your money is equal to 60, so if you divide 60 by 2 you will get 30, which is 1/5 of your money. A way to check if it is right is by multiplying 30 by 5, which is 150, and divide it by 5, to see if it matches (150 : 5 = 30).

hope this helps!

answer:30

explanation:

2/5×X=60

X=150

means your money is 150

so 1/5 of your money is 1/5×150=30
