What is the ratio of 14 days to 3 weeks in simplest form? user: express 3x3x3x5x5 using exponents

1 answer:

7 0

The answer to your question is 3 to the 3rd power and 5 to the 2nd power. The reason why that's your answer is because there are three 3s so instead of doing 3*3*3 you can just simply do 3 to the 3rd power and do the same thing to the 5. You can see that there are two fives so you do 5 to the 2nd power. Hope this helps:)

Using the slope of 7 and y-intercept of (0, 16), write an equation of the line

Katen [24]

Answer:

y = 7x + 16

Step-by-step explanation:

Slope (m) = 7

y - intercept (b) = 16..{from (0, 16)}

Equation of line in slope intercept form is given as:

$y = mx + b \\ \therefore \: y = 7 \times x + 16 \\ \huge \red{ \boxed{ \therefore \: y = 7 x + 16 }}$

find the lower quartile for the data {47.2, 33.8, 43, 62, 5.8, 9, 61.4, 30.8, 68.2, 51.6, 13.2, 17.4, 64.2, 50.6, 29.4, 40.4}

mote1985 [20]

Answer:

The lower quartile is 23.4

Step-by-step explanation:

The given data are;

47.2, 33.8, 43, 62, 5.8, 9, 61.4, 30.8, 68.2, 51.6, 13.2, 17.4, 64.2, 50.6, 29.4, 40.4

Rearranging the data, we have;

5.8, 9, 13.2, 17.4, 29.4, 30.8, 33.8, 40.4, 43, 47.2, 50.6, 51.6, 61.4, 62, 64.2, 68.2

The lower quartile, Q₁, is the (n + 1)/4 th term which is (16 +1)/4 = 4.25th term

However since we have an even set of numbers, we place a separator at the middle and we look for the median of the left half as follows

5.8, 9, 13.2, 17.4, 29.4, 30.8, 33.8, 40.4║ 43, 47.2, 50.6, 51.6, 61.4, 62, 64.2, 68.2

We have two numbers (17.4 + 29.4) at the median of the left set of numbers, we find the average of the two numbers to get the lower quartile

The lower quartile is therefore = (17.4 + 29.4)/2 = 23.4.
