How many students were surveyed about their mode of transportation to school?

AlekseyPX

Answer:

Total number of students surveyed about their mode of transportation to school is 400.

Step-by-step explanation:

Here, given student who uses car as their mode of transport = 120 students

We have to find the total number of students who are surveyed.

Also, since complete circle represents 100% of data,

Total students who uses at least one mode of transport out of foot, bicycle, bus or car let it be x students.

Total percentage of students that uses bus, bicycle and on foot = (20 +15+35)% = 70%

Thus, percentage of students that uses car = 100 - 70 = 30%

Thus, 30 % of total students = 120

Mathematically, 30% of x = 120

Solving for x, we get,

$\frac{30}{100} \times x=120$

$\Rightarrow x=120 \times \frac{100}{30}$

$\Rightarrow x=400$

Thus, total number of students surveyed about their mode of transportation to school is 400.

The mean time from prescription drop-off to medicine pickup for a customer served at Heisenberg's Pharmacy is 64 minutes, with a

kari74 [83]

Answer: B. 0.4772

Step-by-step explanation:

Given : The mean time : $\mu=64\text{ minutes}$

Standard deviation : $\sigma=18\text{minutes}$

Let X be the service time of a randomly selected customer.

Assuming a normal distribution, the value of z-score is given by :-

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

For x = 64

$z=\dfrac{64-64}{18}=0$

For x = 100

$z=\dfrac{100-64}{18}=2$

The p-value = $P(64$

$P(z$

Hence, the probability that a randomly chosen customer experiences service done between 64 and 100 minutes = 0.4772

Write a number sentence that demonstrates each property.

Delvig [45]

They are usually represented like this

commutative property of addition
a+b=b+a

associative property of additon
(a+b)+c=a+(b+c)

identity property of addition
a+0=a

so number sentatnces

lets say a=1,b=2,c=3

commutative property of addition
1+2=2+1

associative property of addition
(1+2)+3=1+(2+3)

identity property of addition
1+0=1
