Answer:

60v

Step-by-step explanation:

1 min: v vehicles

1 hour = 60 mins

60 mins: 60v vehicles

Answer:

60v vehicles / hour

Step-by-step explanation:

Right now, we have: <em>v vehicles / min</em>. We want <em>vehicles / hour</em>.

There are 60 minutes in an hour. So, let's replace hour in the denominator by 60 minutes: we now want <em>vehicles / 60 min</em>.

We see that in order to maintain the one-to-one proportion of vehicles to minutes, we need to multiply the numerator by 60, as well:

<em>60 vehicles / 60 min</em>

<em />

However, we originally had v vehicles, so we just multiply 60 by v. The answer is thus:

60v vehicles / hour

Find the common ratio of the geometric sequence 5, -15, 45,
Lelu [443]

Answer:

-3

Step-by-step explanation:

The common ratio of a geometric sequence is the number that each term of the sequence is multiplied by. This means that the the previous term is multiplied by the common ratio to get the current term. The common ratio can also be used to create a function that can predict future terms.

To find the common ratio of this sequence, divide a term by the previous term. For example, -15/5. This gives the answer, -3. Dividing the terms allows us to figure out what factor is being multiplied by in the sequence.

Ben walked 2/5 mile.Tonya walked 1/4 mile.What fraction of a mile did they walk in total?
sesenic [268]

First, find a common denominator (the bottom number) Then add the tops as usual. Four and five have a common denominator of 20 so: 8/20+5/20=13/20

A population has a mean of 300 and a standard deviation of 70. Suppose a sample of size 125 is selected and is used to estimate
Mrrafil [7]

Answer:

a:  0.8884

b: 0.9934

Step-by-step explanation:

We have µ = 300 and σ = 70.  The sample size, n = 125.  

For the sample to be within 8 units of the population mean, we would have sample values of 292 and 308, so we want to find:

P(292 < x < 308).

We need to find the z-scores that correspond to these values using the given data.  See attached photo 1 for the calculation of these scores.

We have P(292 < x < 308) = 0.8884

Next we want the probability of the sample mean to be within 17 units of the population mean, so we want the values from 283 to 317.  We want to find

P(283 < x < 317)

We need to find the z-scores that correspond to these values.  See photo 2 for the calculation of these scores.

We have P(283 < x < 317) = 0.9934

18. Mabel gave Margo a bag containing red, white, and
Sedbober [7]
So if the bag contains half as many red marbles as blue ones, and there are 8 reds then there are 16 blues. 16 + 8= 24 if you want there to be 1/4 white marbles add 6. 6/30 is 1/4.

So the answer comes out to be 30 marbles in the bag
