Answer:
503.7 is the best estimate when rounding each number to the nearest tenth.
Step-by-step explanation:
Round 552.17 and 48.35 to the nearest tenth. That gives us 552.1 and 48.4 (because 5 makes the number round up). Subtract that, and it gives us 503.7.
Answers:
- 26) probability = 1/4
- 27) probability = 0.0588
- 28) probability = 0.157
=================================================
Work Shown:
26)
1/2 = probability of an odd number, since half of the numbers are odd
1/2 = probability of tails
(1/2)*(1/2) = 1/4 is the probability of both events happening at the same time
----------------------------
27)
13/52 = probability of pulling out one club
12/51 = probability of pulling out a second club, assuming the first one is not put back
(13/52)*(12/51) = 156/2652 = 1/17 = 0.0588 is the probability of pulling two clubs in a row (without replacement).
----------------------------
28)
11/27 = probability first person has blonde hair
10/26 = probability second person has blonde hair (cannot reselect the first person again)
(11/27)*(10/26) = 110/702 = 55/351 = 0.157 is the probability of selecting two people with blonde hair
Answer: 1/3
Explanation: don’t know how to explain
The right answer is Option B.
Step-by-step explanation:
Given system of equations is;
7x-10y=12
8y-x=11
The first step in elimination method is to make one of the variables same to eliminate it, but in this case, we will first rewrite the equations so that alike variables are in same order.
Therefore,
First step is rewrite the equations so like variables are in the same order.
The right answer is Option B.
