Answer:

See Below

Step-by-step explanation:

I'm not going to do the homework for you, but I will complete three of the problems to help you understand the process.

We are converting between different units of measurement.

Here are the conversions to know:

12 inches = 1 foot

3 feet = 1 yard

1760 yard = 1 mile

5280 feet = 1 mile

We need to convert 7 feet into inches.

7 feet * 12 inches per foot = 84 inches

Now we know:

84 inches = 7 feet

What's the difference is between 84 inches, and 18 inches?

84 inches - 18 inches = 66 inches

We need 66 more inches to get a length of 7 feet.

We need to convert 2 miles into yards.

2 miles * 1760 yards per mile = 3520 yards.

Now we know:

3520 yards = 2 miles

What's the difference between 3520 yards and 2000 yards?

3520 yards - 2000 yards = 1520 yards

We need 1520 more yards to make 2 miles

We need to convert 108 inches into feet.

108 inches / 12 inches per foot = 9 feet

Since there is no remainder,

9 feet = 108 inches.

Hopefully you can see what is going on here and do the rest yourself.

After m months, the height of a plant is 10+3m millimeters. How tall is the plant after eight months? Three years?

Oksanka [162]

Why not start out by writing a linear relationship for the plant height?

h(m) = 10 + 3m, where h is the height in mm and m is the time in years, starting from zero (0).

After 8 months, the plant height is h(8) = 10 mm + 3(8) mm, or 34 mm.

After 3 years (36 months), the plant ht. is h(36) = 118 mm.

A manufacturer of bolts has a quality-control policy that requires it to destroy any bolts that are more than 2 standard deviat

n200080 [17]

bolts of length more than $13+0.2$ , and less than $13-0.2$ will be destroyed

= 13.20 cm and 12.80 cm

<u>Step-by-step explanation:</u>

Here we have , A manufacturer of bolts has a quality-control policy that requires it to destroy any bolts that are more than 2 standard deviations from the mean. The quality-control engineer knows that the bolts coming off the assembly line have mean length of 13 cm with a standard deviation of 0.10 cm. We need to find For what lengths will a bolt be destroyed .Let's find out:

A manufacturer of bolts has a quality control policy that requires it destroy any bolts that are more than 2 standard deviations from the mean.

mean length= $13 cm$

standard deviation= $0.10 cm$

2 standard deviation from mean= $13 \pm (2(0.10))$

Therefore, bolts of length more than $13+0.2$ , and less than $13-0.2$ will be destroyed

= 13.20 cm and 12.80 cm

How did you find it and what is the anwser

Ray Of Light [21]

This is fairly simple
multiply the number by 10 until there is no decimal
then put the number over that
13008/1000
Now simplify
1626/125
OR
13 1/125

Evelyn believes that if she flips a coin 480 times, it will land tails up exactly 240 times. What would you tell Evelyn about he

RideAnS [48]

You'd say that although that seems correct, since there's a 50/50 chance of each outcome, it doesn't necessarily guarantee that it will ALWAYS be 50/50. However, her guess has the highest probability of occurring, or in other words, its more likely that it'll be somewhere close to 240 rather than in the 100's or 300's.
