Answer:

Standard Description: Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions. (Grade 4 expectations in this domain are limited to fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100.)

The best way to achieve significant increases in interest after all in a savings account is through?
Alekssandra [29.7K]

Answer: The answer is (d) Compounding.

Step-by-step explanation:  We are given four options out of we are to select the best way through which we can achieve significant increases in interest after all in a savings account.

Increases in principle and increases in time will not give the result, because we are talking about a fixed amount of money for a fixed time.

Also, increases in interest is not in our hand.

So, only we can do is compounding. Here, in same amount of money and time, the rate of interest will automatically increase.

Thus, the correct option is (d) Compounding.

Will 5x-3y>15 have a solid line
marysya [2.9K]

Answer:

The inequality 5x-3y >15 have a dashed line

Step-by-step explanation:

we have

5x-3y >15

The solution of this inequality is the shaded area below the dashed line

The equation of the dashed line is 5x-3y=15

The slope of the dashed line is positive

The y-intercept of the dashed line is -5 ---> point (0,-5)

The x-intercept of the dashed line is x=3 ----> point (3,0)

Graph the solution

A screening test for a certain disease is used in a large population of people of whom 1 in 1000 actually have the disease. Supp
sertanlavr [38]

Answer:

P(D/T)=5.05*10^{-6}

Step-by-step explanation:

Let's call D the event that a person has the disease, D' the event that a person doesn't have the disease and T the event that the person tests negative for the disease.

So, the probability P(D/T) that a randomly chosen person who tests negative for the disease actually has the disease is calculated as:

P(D/T) = P(D∩T)/P(T)

Where P(T) = P(D∩T) + P(D'∩T)

So, the probability P(D∩T) that a person has the disease and the person tests negative for the disease is equal to:

P(D∩T) = (1/1000)*(0.005) = 0.000005

Because 1/1000 is the probability that the person has the disease and 0.005 is the probability that the person tests negative given that the person has the disease.

At the same way, the probability P(D'∩T) that a person doesn't have the disease and the person tests negative for the disease is equal to:

P(D'∩T) = (999/1000)*(0.99) = 0.98901

Finally, P(T) and P(D/T) are equal to:

P(T) = 0.000005 + 0.98901 = 0.989015

P(D/T) = 0.000005/0.989015 = 5.05*10^{-6}
