Gisselle has 1/2 of a candy bar. She role off 1/2 of what she had. She then took the piece she broke off and split it into three
saul85 [17]

Answer:

\frac{1}{12}

Step-by-step explanation:

Given:

Gisselle has 1/2 of a candy bar.

She role off 1/2 of what she had and split it into three equal pieces.

Question asked:

What fraction of a candy bar was each piece?

Solution:

Gisselle has = \frac{1}{2} \ of \ a \ candy \ bar

She role off = \frac{1}{2} \ of \ what\ she \ had

                     =\frac{1}{2}  \ of\  \frac{1}{2}\\=\frac{1}{2} \times \frac{1}{2}\\\\=\frac{1}{4}

As she split it into three equal pieces, we will divided it by 3, we get,

\frac{1}{4} \div3\\\frac{1}{4}\times\frac{1}{3}

\frac{1}{12}

Therefore, fraction of a candy bar of each piece is \frac{1}{12}

Reels produced at 800 per day but production cut by 1/5. They have an order for 20,000 reels. Can they produce enough in 30 days
Neko [114]

The company can not produce enough reels.

Step-by-step explanation:

Reels produced per day = 800

Production cut = 1/5

Let, the daily production be 1.

therefore,

New per day production = 1-\frac{1}{5}=\frac{5-1}{5}

New per day production = 4/5

Therefore,

4/5 of 800 = New no. of reels produced per day

\frac{4}{5}*800 = New no. of reels

640 = New no. of reels

New. no of reels produced per day = 640

Reels produced in 30 days = 640*30 = 19200

The company can not produce enough reels.

In a random sample of fivefive microwave​ ovens, the mean repair cost was ​$75.0075.00 and the standard deviation was ​$13.0013.
Radda [10]
<h2>Answer with explanation:</h2>

As per given , we have

Sample size : n= 5

Degree pf freedom = : df= 5-1=4

\mu=\$75.00

\sigma=\$13.00

Significance level for 90% confidence = \alpha=1-0.90=0.1

Using t-value table , t-critical value for 90% confidence:

t_{\alpha/2, df}=t_{0.05, 4}=2.132.

Margin of error of \mu: E=t_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\(2.132)\dfrac{13}{\sqrt{5}}=12.3949720129\approx12.39

Interpretation : The repair cost will be within $12.39 of the real population mean value \mu 90% of the time.
