4 times 7 = 28
3 times 7 = 21
It will take him 21 days to make 28 bird houses.
100x 0.18 as it equals 18 when you multiply it
so i am sure you know that 1 hour is sixty minutes
so this is how it woulds
10/1 * 60/1 = 600 minutes
so that means that 10 hours would be equal to 600 minutes
then add on the 39 minutes
639
BUT WAIT there are the seconds
24/1 * 1/60 = 0.4
so 24 seconds is 0.4 (40%) of a minute
so it would take 639.4 minutes for saturn to make a full rotation
i hope this helped and please vote me for brainliest! have a nice day!
Answer:
25.12
Step-by-step explanation:
The formula of the circumference of a circle is: C = 2(pi)(r)
Plug in 3.14 for pi and 4 for the radius.
C = 2(3.14)(4)
Multiply.
C = 25.12
Answer:
95%
Step-by-step explanation:
About 95% of the area is within two standard deviation in standard normal distribution. This can be explained by finding the probability within 2 standard deviation using standard normal distribution.
P(z1<Z<z2)=P(-2<Z<2)
P(-2<Z<2)=P(-2<Z<0)+P(0<Z<2)
P(-2<Z<2)=0.4772+0.4772
P(-2<Z<2)=0.9544
Thus, About 95% of the area is between z2 and z2
