Answer:

\frac{3}{19} x 12 =

Step-by-step explanation:

\frac{3}{19} x 12

Multiply the fractions:

\frac{\left(3\cdot12\right)}{19} 3 x 12 = 36 and then 19 is the same so its 36 over 19

Simplify the arithmetic:

\frac{36}{19}

Decimal result 1.895

or even simpler 1 \frac{17}{19}

Show and explain how you found the answer to this problem. Marion read 616 pages in 14 days. If she read the same number of page
Pepsi [2]

Based on the number of pages read and the time it was read in, the number of pages read per day was <u>44 pages. </u>

Marion read 616 pages and did this in 14 days.

She read the same number of pages each day so the number of pages read per day was:

<em>= Number of pages read in total / Number of days </em>

= 616 / 14

= 44 pages

In conclusion, she read 44 pages per day.

Jason inherited a piece of land from his great-uncle. Owners in the area claim that there is a 45% chance that the land has oil.
Licemer1 [7]
So,

We are trying to find the compound probability of there BEING oil and the test predicting NO oil.

The percent chance of there actually being oil is 45%.  We can convert this into fraction form and simplify it.

45% --> \frac{45}{100}

\frac{45}{100}--\ \textgreater \  \frac{3*3*5}{2*2*5*5}

\frac{3*3*5}{2*2*5*5}--\ \textgreater \ \frac{3*3}{2*2*5}

\frac{3*3}{2*2*5}--\ \textgreater \  \frac{9}{20}

That is the simplified fraction form.

The kit has an 80% accuracy rate.  Since we are assuming that the land has oil, we need the probability that the kit predicts no oil.  

The probability that the kit detects no oil will be the chance that the kit is not accurate, which is 20% (100 - 80 = 20).  We can also convert this into fraction form and simplify it.

20% --> \frac{20}{100}

\frac{20}{100}--\ \textgreater \ \frac{2}{10}

\frac{2}{10}--\ \textgreater \ \frac{1}{5}

That is the probability of the kit not being accurate (not predicting any oil).

To find the compound probability of there being oil and the kit not predicting any oil, we simply multiply both fractions together.

\frac{9}{20}*\frac{1}{5}

\frac{9}{20*5}

\frac{9}{100}

So the probability of there BEING oil and the kit predicting NO oil is 9 in 100 chances.

Find the critical value from the Studentized range distribution for H0: μ1 = μ2 = μ3 = μ4 = μ5, with n = 35 at α = 0.01. Provide
Aleonysh [2.5K]

Answer:

t-value = 2.441

Step-by-step explanation:

Let's assume that this is a one-tailed test to calculate the critical value, the process is this:

  • Calculate alpha (α): α = 1 - (confidence level / 100) , but we already have this α=0.01
  • Find the critical probability (p*): p* = 1 - α/2  = 1-0.005=0.995
  • Then, the critical value would be shown as a t statistic, but for this we need:

degrees of freedom (df)= n-1=35-1=34

  • The critical t statistic (t*) or critical value is the t-value having degrees of freedom equal to 34 and a cumulative probability equal to 0.995.

From the attached table we can see:

t-value = 2.441

Scott made 3 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 3 necklaces
pantera1 [17]

Answer:

$2.90

Step-by-step explanation:

<u>Lets look at the information given:</u>

Scott made 3 necklaces

$14.40 is the cost for both the beads and pendants for all 3 necklaces

$5.70 was the cost of just beads for all 3 necklaces

Each necklace has 1 pendant

The first step to solving this equation is subtracting the cost of the beads from the total cost for the necklaces:

$14.40 - $5.70= $8.70

Now we know that cost for the 3 pendants for all 3 necklaces was $8.70, but we need to find how much EACH pendant costs. To find out, we simply divide the total cost for all 3 pendants by 3:

$8.70 ÷ 3 = $2.90

So each pendent costs $2.90
