Answer:

n=8

Let the sum be x

Now

mean = sum/n

136.5 = x/8

or, 136.5 × 8 = x

so, x = 1092

So, (c)1092 is the correct answer.

1092 so it’s c the mean is adding all the numbers and dividing it by the amount of numbers so for example 1 2 3 the mean would be 1+2+3/3 since there are 3 numbers hope this helps

1. Percent error is | \frac{guess-actual}{actual}|
The guess is 15.5mi, and the actual distance is 14.5 mi.
Percent error is | \frac{15.5-14.5}{14.5}|=0.69=6.9%

2. The cost will be $31.95*(1+0.075) = $34.35
The 1 represents 100% of the original amount of $31.95, and now we add 7.5% (0.075) to the 100%. In other words we multiply $31.95 by 107.5%.

3. His commission will be $165 out of $4125, or $165/$4215 = 0.039 = 3.9%

4. The principal (amount of money you start with) is $12000, and the interest rate is 15% of that.
15% of $1800 = 0.15*$12000 = $1800

A scuba diver dives 243 feet into the ocean and then swims up 156
wariber [46]

Answer:

Her final position would stop at -87.

Step-by-step explanation:

As she dove 243 feet into the ocean, that means she went down. Therefore she's currently at -243, however she swam up 156 feet ending her up at -87. If that was kinda complicated, then use -243+156 and you'll get -87.

Choose which function is represented by the graph
Viefleur [7K]

Given:

The graph of a function.

To find:

The function.

Solution:

From the given graph, it is clear that the graph intersect the x-axis at x=-4, -2, 1. It means -4, -2 and 1 are zeros of the given function graph.

If c is a zero of a function f(x), then (x-c) is a factor of f(x).

Using the above definition, we conclude that (x+4), (x+2) and (x-1) are the factors of given function. So,

f(x)=(x+4)(x+2)(x-1)

f(x)=(x-1)(x+2)(x+4)

Therefore, the correct option is A.
