(5 3/10) (m) + (5 3/10) (m) + (5 3/10) (m) + (5 3/10) (m)

P = 53/10 + 5 3/10 + 5 3/10 + 5 3/10

P = 53/10 + 53/10 + 5 3/10 + 5 3/10

P = 53/5 + 5 3/10 + 5 3/10

P = 53/5 + 53/10 + 5 3/10

P = 159/10 + 5 3/10

P = 159/10 + 53/10

P = 106/5

P = 21 1/5 meters

Answer: 21 1/5 meters (Decimal: 21.2m)

Hope that helps!!!! Have a great day!!!! : )

The number of students using the ATM on campus daily is normally distributed with a mean of 240 and a standard deviation of 50.
damaskus [11]

Answer:

The probability is 0.080757

Step-by-step explanation:

We start by calculating the z-score

z-score = (x-mean)/SD/ √n

In this case;

x = 247 , mean = 240, SD = 50 and n = 100

z-score = (247-240)/50/√100

z-score = 7/50/10

= 7/5 = 1.4

So the probability we want to calculate is;

P( x > 1.4)

we can use the standard normal distribution table for this

P(x > 1.4) = 0.080757

Trucks in a delivery fleet travel a mean of 80 miles per day with a standard deviation of 30 miles per day. The mileage per day
bulgar [2K]

Answer:  0.1037

Step-by-step explanation:

Given : Mean : \mu=80\text{ miles per day}

Standard deviation : \sigma = 30\text{ miles per day}

The formula to calculate the z-score is given by :-

z=\dfrac{x-\mu}{\sigma}

For x = 97 miles per day ,

z=\dfrac{97-80}{30}\approx0.57

For x = 107 miles per day ,

z=\dfrac{97-80}{30}=0.9

The P-value =P(0.57

=0.8159398-0.7122603=0.1036795\approx0.1037

Hence, the probability that a truck drives between 97 and 107 miles in a day = 0.1037
