Answer:

z = 1.476

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.86}{2} = 0.07$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.07 = 0.93$ , so $z = 1.476$

The answer is z = 1.476

Tina is saving to buy a notebook computer. She has two options. The first option is to put $500 away initially and save $30 ever

r-ruslan [8.4K]

Answer:

10 months. Each plan will save 800 dollars.

Step-by-step explanation:

500 + 30x = y

300 + 50x = y

You want the months to give the same amount of money. The x has to be the same for both

500 + 30x = 300 + 50x Subtract 300 from both sides

500 - 300 + 30x = 50x Combine

200 + 30x = 50x Subtract 30x from both sides

200 = 50x - 30x Combine

200 = 20x Divide by 20

x = 10

So in 10 months time the amounts will be the same. How much will there be?

500 + 30*10 = 500 + 300 = 800

300 + 50*10 = 300 + 500 = 800

Lisa has \dfrac{1}{3} 3 1 start fraction, 1, divided by, 3, end fraction of an hour to read and watch television. She wants to

ikadub [295]

Answer:

Lisa spends $\frac{1}{6}\ hrs$ in reading and $\frac{1}{6}\ hrs$ in watching television.

Step-by-step explanation:

Given:

Number of hours Lisa has = $\frac{1}{3}$

Now we need to find number of hours required to watch television and to read.

Given:

She splits her time equally between 2 activities.

Hence we can say;

Number of hours required to watch television and number of hours required to read both are half times equal to total number of hours.

Hence framing the equation we get;

Number of hours required to watch television = $\frac{1}{2} \times \textrm{Total Number of hours she has}$

Substituting the value we get;

Number of hours required to watch television = $\frac{1}{2} \times \frac{1}{3} = \frac{1}{6}\ hrs$

Number of hours required to read = $\frac{1}{2} \times \textrm{Total Number of hours she has}$

Substituting the values we get;

Number of hours required to read = $\frac{1}{2} \times \frac{1}{3} = \frac{1}{6}\ hrs$

Hence Lisa spends $\frac{1}{6}\ hrs$ in reading and $\frac{1}{6}\ hrs$ in watching television.
