To write in standard form, we have to move the decimal point in

3.42

over 3 places to the left since our exponent is 10 3

This gives us our answer of

0.00342

Hope this helps.

Paladinen [302]

When you divide two fractions, you're actually multiplying one of them by the reciprocal of the other. First, find the reciprocal of the second fraction by flipping it upside down. Then, multiply it by the first fraction. (Numerator x numerator and denominator x denominator)

$\frac{-7}{12}$ ÷ $\frac{2}{3}$ Replace the second fraction with it's reciprocal
$\frac{-7}{12}$ x $\frac{3}{2}$ Multiply (-7 x 3 and 12 x 2)
$\frac{-21}{24}$ Both 21 and 24 are divisible by three, so divide them by 3
$\frac{-7}{8}$

Please help for D, E and F

Phantasy [73]

D) 24/65 because it represents the number of players with 1-5 years of experience out of the overall total interviewed.

E) 3/11 because out of the eleven rookies, only three of them were under 200 lbs.

F) out of the 8 that reported to be under 200 pounds, only 3 were rookies, so the probability is 3/8

A simple random sample of 100 batteries is selected from a process that produces batteries with a mean lifetime of 32 hours and

Brrunno [24]

Answer:

.b. It is one‐half as large as when n = 100.

Step-by-step explanation:

Given that a simple random sample of 100 batteries is selected from a process that produces batteries with a mean lifetime of 32 hours and a standard deviation of 3 hours.

i.e. s = 0.3

we obtain se of sample by dividing std devitation by the square root of sample size

i.e. s= $\frac{3}{\sqrt{n} }$

when n =100 this = 0.3 and

when n =400 this equals 0.15

We find that when sample size is four times as large as original, std deviation becomes 1/2 of the original

Correction option is

.b. It is one‐half as large as when n = 100.

aalyn [17]

Given that Audra was drawing a perpendicular bisector of segment AB with a compass. She started with line segment AB. Then, she placed her compass point on A and opened the compass more halfway to B.

Her next step will be "Using the width of the compass from the previous step, draw two arcs to the left and right of both A and B".
