We know that , the 95% confidence interval indicates that the researcher can be 95% sure that the true value of population mean falls in it.

Given : A company is interested in estimating the costs of lunch in their cafeteria.

After surveying​ employees, the staff calculated that a​ 95% confidence interval for the mean amount of money spent for lunch over a period of six months is ​($720​, ​$900​).

Then, the correct interpretation would be : The company can be 95% sure that the true value of population mean falls in it.

HELP ME !! AND EXPLAIN HOW YOU GOT IT.
Juli2301 [7.4K]

Answer: G = 50°, I = 50°, H = 80°

Step-by-step explanation:

First and foremos, the sum of three angles of a triangle is 180°

2x + 2x + (4x - 20) = 180°

8x - 20 = 180°

8x = 180° + 20 (adding 20 on both sides)

8x = 200°

x = 200/8

x = 25

The value of the angles can be found by replacing the value of x with 25

2x = 2 x 25 = 50°

Therefore, the angle of two angles are 50°

And the other is (4 x 25) -20 = 80°

If Jan jogged 7x - 12 miles and Julie jogged 35x - 60miles , how many times longer was Julie's travel distance than Jan's?
OLEGan [10]

Answer:

Julie jogged five times further than Jan.

Step-by-step explanation:

We can find this solution just by dividing Julie's distance by Jan's:

\frac{35x - 60}{ 7x - 12} \\\\= \frac{5(7x - 12)}{ 7x - 12} \\\\= 5

So Julie jogged five times further.

Can someone give me the answers for these?
Katyanochek1 [597]

Answer:

a.  He started with $50 in the the account.

b.  The account grow by $10 dollars each week

c see graph

Step-by-step explanation:

y = 50 + 10x


We can rewrite this as

y = 10x+50

This is in the form y = mx+b

where m = 10 which is the slope and b =50 which is the y intercept

The y intercept = 50 is the starting value or the value when x = 0

a.  He started with $50 in the the account.


The slope is how much it grows by as x grows.  As x increase by 1 , y will grow by the slope or 10, so  the account will grow by 10 each week.

b.  The account grow by $10 dollars each week


c see graph
