Answer:
0.595
Step-by-step explanation:
We are given that An archer hits centre of the target
We have to calculate the probability that she will hit the centre of the target on two consecutive shots.
P(A)=P(B)=0.70
P(B/A)=0.85
We know tha formula
Substitute the value then we get
Hence, the probability that she will hit the centre of the target on two consecutive shots=0.595
Area of rectangle is width × length
which means area of rectangular floor in Tamara's room = width of room × length of room
-> 95 ⅚ sq feet = 8 ⅓ feet × length of
->(95 + 5/6) sq feet = (8 + 1/3) feet × length of room
->575/6 sq feet = 25/3 feet × length of room
length of room = (575/6)/(25/3)
= 575 × 3/6 × 25)
= 23/2
= 11 ½ feet

Answer:
<em>Tom must score 95 on his last test</em> to have an average of 92.
Step-by-step explanation:
Tom's average score (92) = the sum of all his five grades/the number of grades (5)
Given that A is the grade Tom must receive on his last test, we have the equation as follows:
92 = (89+94+86+96+A)/5
<=> A = 92 × 5 - (89+94+86+96)
=> A = 95
