We want to know what is the basis of al units in tne metric system. The metric system is a set of decimal-based prefixes that have the effect of multiplication or division by the integer power of ten. Which means that when we have some unit like a meter or a kilogram, to get to the smaller unit we need to divide by the integer power of ten or when we want a greter unit we need to multiply the unit by the integrer power of ten. So the corret answer is D.

sertanlavr [38]

Answer:

0.0791

Step-by-step explanation:

Given that the probability of white eyes is 1/4 and the probability of red eyes is 3/4, for an individual fly.

Observations are independent

Let A be finding the white eyed fly and B

finding the red eyed fly

P(A) for any random trial= 0.25 and

P(B) = 0.75

Each trial is independent of the other

The probability that at least four flies have to be checked for eye color to observe a white-eyed fly

=Probability for I, II, III and Iv flies to have red eyes * Prob for 5th fly to have white eye

= $0.75^4(0.25)\\=0.0791$

A boat can travel at an average speed of 10 miles per hour in still water. Traveling with the current, it can travel 6 miles in

oksano4ka [1.4K]

Answer: The speed of the current is 2 miles per hour.

Step-by-step explanation:

We know that the speed of the boat is:

S = 10 mph.

When the boat travels with the current, the speed will be:

S = 10mph + x

where x = speed of the current.

When the boat travels against the current, the speed will be:

S = 10mph - x

Now, for a given amount of time T, when the boat travels with the current, it moves a distance of 6 miles.

Then we have the equation:

(10mph + x)*T = 6mi

And against the current, in the same time the boat moves 4 mi, then:

(10 mph - x)*T = 4mi

Then we have the system of equations:

(10mph + x)*T = 6mi

(10 mph - x)*T = 4mi

Now, we can take the quotient of these two equations and get:

((10mph + x)*T)/((10 mph - x)*T) = (6mi/4mi)

(10mph + x)/(10 mph - x) = 3/2

Now we can solve this for x.

(10mph + x) = (3/2)*(10 mph - x)

10mph + x = (3/2)*10mph - (3/2)*x

x + (3/2)*x = (3/2)*10mph - 10mph

(5/2)*x = (1/2)*10mph = 5mph

x = (2/5)*5mph = 2mph.

The speed of the current is 2 miles per hour.

Margarita [4]

Answer:

a. When two variables change in the same direction, one remaining larger than the other by the same factor - direct relationship

b. To insert between neighboring points or estimate by taking an average of known values - interpolate

c. A relationship between two variables in which the product remains constant. When one variable increases the other decreases in proportion so that the product is unchanged - inverse relationship
