arlik [135]

First, we need to find the total fraction of her raisins she used:

1/4 + 3/8 = 2/8 + 3/8

She used 5/8 of her supply.

Knowing this:

5/8x = 5

We multiply by 8 (the LCD)

5x = 40

x = 8

Her supply was 8 pounds, and after making the food, she now has 3 pounds

What is the answer to x-1=-5-x

maria [59]

Answer:

$x=-2$

Step-by-step explanation:

We have the equation $x-1=-5-x$

In order to solve for x, we need to get all of the x's to one side and everything else to the opposite side

$x-1=-5-x$

First, we can add 1 to each side

$x=-4-x$

Now, we can add x to each side

$2x=-4$

Next, we can divide each side by 2

$x=-2$

And here is our answer.

A company that produces computers recently tested the battery in its latest laptop in six separate trials. The battery lasted 8.

Anna35 [415]

confidence interval for the mean battery life in the new model is [7.9489, 8.3045].

What is confidence interval ?

A confidence interval, in statistics, refers to the chance that a population parameter can fall between a collection of values for an exact proportion of times.

Main body:

Formula for confidence interval is =

CI = x- bar ± z*s/√n where,

CI = confidence interval

x- bar = sample mean

z = confidence level value

{s} = sample standard deviation

{n} = sample size

given ;

n = 6

mean = (8.23+7.89+8.14+8.25+8.30+ 7.95)/6

= 8.127

value of z for 95% C.I. = 1.96

C.I. = 8.127 ± 1.96 * 0.22/√6

C.I. = 8.127 ± 0.1781

C.I. =[7.9490, 8.3044]

Hence correct option is A.
