Answer:

8v + 9v - v

Step-by-step explanation:

Solving all options...

8v + 6v + 3v

=> 17v

3(v + 2) + 11v

=> 3v + 6 + 11v

=> 6 + 14v

2(4v + 8v)

=> 8v + 16v

=> 24v

8v + 9v - v

=> 16v

The last option is the only one that equals 16v, therefore, it would be the right answer.

Hope this helps!

Saiges spaceship traveled 588 kilometers in 60 seconds. Determine whether or not each spaceship trip below has the same speed as

Fiesta28 [93]

Answer:

Part 1) 441km in 45s --> Has the same speed as Saige's spaceship

Part 2) 215km in 25s --> Does not have the same speed as Saige's spaceship

Part 3) 649km in 110s --> Does not have the same speed as Saige's spaceship

Step-by-step explanation:

The complete question is

Saige's spaceship traveled 588 kilometers in 60 seconds.

Determine whether or not each spaceship trip below has the same speed as Saige's spaceship.

441km in 45s

215km in 25s

649km in 110s

we know that

The speed is equal to divide the total distance traveled by the total time

In this problem we have that

The speed of Saiges spaceship is equal to

$\frac{588}{60}=9.8\ \frac{km}{sec}$

case 1) we have

441km in 45s

Find out the speed of the spaceship trip

$\frac{441}{45}=9.8\ \frac{km}{sec}$

Compare the speed of the spaceship trip with the speed of Saiges spaceship

$9.8\ \frac{km}{sec}=9.8\ \frac{km}{sec}$

therefore

Has the same speed as Saige's spaceship

case 2) we have

215km in 25

Find out the speed of the spaceship trip

$\frac{215}{25}=8.6\ \frac{km}{sec}$

Compare the speed of the spaceship trip with the speed of Saiges spaceship

$8.6\ \frac{km}{sec}\neq 9.8\ \frac{km}{sec}$

therefore

Does not have the same speed as Saige's spaceship

case 3) we have

649km in 110s

Find out the speed of the spaceship trip

$\frac{649}{110}=5.9\ \frac{km}{sec}$

Compare the speed of the spaceship trip with the speed of Saiges spaceship

$5.9\ \frac{km}{sec}\neq 9.8\ \frac{km}{sec}$

therefore

Does not have the same speed as Saige's spaceship

1. A population with a normal distribution has a mean of 104 and standard deviation 15. A sample of 30 items is taken from that

Pie

Answer:

0.3575

Step-by-step explanation:

A population with a normal distribution has a mean of 104 and a standard deviation of 15. A sample of 30 items is taken from that population. (a) (4 points) What is the probability of the sample mean is not less than 103?

The probability of the sample mean is not less than 103 means the sample mean is equal to 103

We solve using the z score formula

z = (x-μ)/σ/√n

where

x is the raw score = 103

μ is the population mean = 104

σ is the population standard deviation = 15

n is the random number of sample = 30

z = 103 - 104/15/√30

z = -1/2.7386127875

z = -0.36515

Probability value from Z-Table:

P(x≤ 103) = 0.3575

Therefore, the probability of the sample mean is not less than 103 is 0.3575

How many deli sandwiches did she make? Please help me.

SpyIntel [72]

Answer: 6 sandwiches

Step-by-step explanation:

To get the amount of roast beef that Marissa used you would have to subtract 2 3/4 from 5...which is 2.25 pounds of beef that she used.

Then you would divide 2.25 by 3/8 which is 6... meaning Marisa made 6 sandwiches!
