Answer:
19
Step-by-step explanation:
Answer:
turn into improper fractions
1*24+16=40
40/24
1*24+21=45
45/24
40/24+45/24=85/24
work out how many times 24 goes into 85 to get back to a mixed number.
24 goes into 85 three times with 13 left over so the answer is
3 and 13/24

Step-by-step explanation:
to buy fencing, you need to find the perimeter of the pen. The perimeter is found by adding all sides together.
So, 13+13+2x+2x=4x+26
Answer:
1. 0.1635
2. 0.0026
Step-by-step explanation:
The computation of the probability in the following cases are as follows:
1.
Given that
Mean = 25 minutes
ANd, the standard deviation is 6.1 minutes
So here the z score would be
= (31 - 25) ÷(6.1)
= 0.98
Now the probability is
= P(Z>0.98)
= 0.1635
2. the z score would be
= (8 - 25) ÷(6.1)
= -2.79
Now the probability is
= P(Z<-2.79)
= 0.0026
