eimsori [14]

Answer:

The length EF is 7 units.

Step-by-step explanation:

The length between the points E and F, using the plot below, is:

$\bar{EF}=7\: u$

Therefore the length EF is 7 units.

I hope it helps you!

The measurement of a central angle is 75. Find the measurement of in radians

Marina CMI [18]

Circumference = 360 degrees
Circumference = 2π radians (comes from 2*pi*radius) 

Therefore 
360 deg. = 2*π radians 
180 deg. = π radians 
1 deg. = (π/180) radians 

75 deg. = 75(π/180) radians 
75 deg. = 75π / 180 radians 
don't bother to try and simplify π (it is an irrational number) 
however you can simplify 75/180 
both are divisible by 5 
75π/180 = 15π/36 
both are divisible by 3 
75 deg. = 5π/12 radians 

We normally don't bother to go further, unless you actually need it as a decimal fraction (in which case, you will have an approximation) 

75 deg. ≈ 1.308997 radians

The heights of 500 students at a local school were recorded and found to be approximated by the normal curve below. Which

Sunny_sXe [5.5K]

Answer:

option C.

Step-by-step explanation:

The given graph is the bell shaped graph.

From the graph we can observe that the peak is at 69.

So, the mean of the data is = 69 .

Standard deviation is the deviation of the graph from the mean value.

= 72-69 = 3

Hence, the standard deviation is equal to 3.

So, the correct answer is option C.

lan ran 24 laps in a charity run and then walked 0.2 kilometer to the presentation table the total; distance lan traveled was 29

QveST [7]

Answer:

Step-by-step explanation:

1.225km is equal to each laps

Step-by-step explanation:

Since Kristy total distance traveled = 29.6km

And Kristy ran 24 laps and later walk 0.2km. it simply implies that

Total distance traveled = distance covered running + distance covered walking

Since we know that

Total distance traveled = 29.6km

distance covered running = 24 laps

distance covered walking = 0.2km

Distance covered running in km = total distance traveled - distance covered walking

Distance covered running in km = 29.6km - 0.2km = 29.4km.

To now find the distance for each lap.

Since we have:

Distance covered running in km = 29.4km.

Distance covered running in lap = 24 laps

i.e

24 laps = 29.4km

1 lap = x

Use cross-multiple

24 laps * x = 29.4km × 1 lap

x = 29.4km / 24

x = 1.225km

Therefore

1.225km is equal to each laps.
