Log2(3x-7)=3?what is the answer

Mathematics
1 answer:
Mama L [17]3 years ago
6 0

Answer:

x = 5

Step-by-step explanation:

Your statement says, "the log to the base 2 of 3x - 7 is 3" and you want to find the value of x.

Here the base is 2, obviously.

 log to the base 2 of 3x - 7                        3

2                                                  equals   2

and this simplifies to 3x - 7 = 8.  Adding 7 to both sides, we get 3x = 15.

Thus, x must be 5.

PLEASE HELP! 10 POINTS! The pie chart shows the breakdown of sales for a sporting goods store. If the store made 4,560 sales, ho
soldier1979 [14.2K]

Answer:

≈ 502

Step-by-step explanation:

The pie chart shows that shirts made up 11% of the sales made by the sporting goods store.

The number of sales that were shirts = 11% of the total sales

Total sales made by the store is given as 4,560

Number of sales that were shirts = 11/100 × 4,560

= 0.11 × 4,560

= 501.6

Number of sales made that were shirts is approximately 502.

A set of data with 100 observati removed, what is the mean of the new data se of 267 There are six outliers in the data set, whi
Andreas93 [3]

Answer:

<u>the mean-average of the data without the outliers is 22572/94 = 240.12766 correct to four digits.</u>

Step-by-step explanation:

If the six outliers are removed, what is the mean average of the remaining data... is ASSUMED what the question was supposed to ask. I'll go out on a limb here, because there really isn't much else you can calculate with just

this much data anyways. I refer to the mean or average as the mean-average....just sayin'

 

Mean-Average = total/count , which means the total = count * mean-average.

 

Well, the data containing the outliers has a mean-average of 267 and a count of 100 statistics as given in the problem. So the total of all of the data including the outliers is 26700.

 

Likewise, the six outliers have a mean-average of 688 as given in the problem.

So the total of the outliers is 688 * 6 = 4128.

 

As a result, the total of the 94 statistics when the six outliers are rejected is 26700-4128=22572.

Nutka1998 [239]
Hi!

Imagine a rectangle with a width of 20 inches, and a height of 16. Find the length around the rectangle (the perimeter).

16+20+16+20=72

There are 12 inches in a feet. How many feet are in 72 inches?

72/12=6

Lana needs 6 feet of ribbon. She bought 7 feet.

7-6=1

It is enough ribbon.
1 foot will be leftover.

Hope this helps! :)
