If the area of a square garden is 1/81km2 
that means 2 sides were multiplied to find the area. 
since it is a square all sides are the same, what number multiplied by itself equals 1/81...
1/9 x 1/9 equals 1/81 
which means each side is 1/9km

How can I condense this expression into a single logarithm?
Sholpan [36]
Because they have the same base you can When you subtract logs of the same base you divide them Aka log5-log4= log(5/4) Similarly when you add you multiply Aka log5+log4= log (5*4) Make sure they have the same base like in your problem

Suppose that the average and standard deviation of the fine for speeding on a particular highway are 111.12 and 13.04, respectiv
antoniya [11.8K]

Answer:

3) (98.08, 124.16)

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 111.12

Standard deviation = 13.04

Calculate an interval that is symmetric around the mean such that it contains approximately 68% of fines.

68% of the fines are within 1 standard deviation of the mean speed. So

From 111.12 - 13.04 = 98.08 to 111.12 + 13.04 = 124.16

The interval notation in the smallest value before the highest value.

So the correct answer is:

3) (98.08, 124.16)

There are three consecutive even integers. If twice the first integer added to the second is 268, 244 find all three integers.
Rudik [331]

Answer:

The numbers would be 89,414 , 89,416, and 89,418

Step-by-step explanation:

In order to find this, start by setting the lowest number as x. Then we can determine that the next two even integers are x + 2 and x + 4. From this we can write the following equation.

2(x) + x + 2 = 268,244

3x + 2 = 268,244

3x = 268,242

x = 89,414

Since the first number is 89,414, we know the next two are 89,416 and 89,418.
