- - He runs 1.5 meters each second.
- Solve:
Divide 30/20
<span>=1.5
</span>To answer this we will divide the amount of meters by the amount of seconds. Then your answer will be the amount of meters Earl runs per second. Then we will check our work. Lets do it:-
30 ÷ 20 = 1.5
1.5 meter per second.
CHECK OUR WOK:-
1.5 × 20 = 30
<span>We were </span><span>RIGHT!!
</span><span>So, </span><span>1.5 meters per sec.</span>
Answer:
Step-by-step explanation:
you could subtract and divid
1. Three consecutive integers: x, x+1, x+2, such that:
x + x + 1 + x + 2 = 120
3 x + 3 = 120
3 x = 117
x = 117:3= 39
The integers are: 39,40,41.
2.
x + x + 2 = x +1 +21
2 x - x = 22 - 2
x = 20
The integers are: 20,21,22.
3. Four consecutive even integers: x, x+2, x+4, x+6
4 ( x + x + 2 ) = 7 (x + 6 ) - 8
8 x + 8 = 7 x + 42 - 8
8 x - 7 x = 34 - 8
x = 26
The integers are: 26, 28, 30 , 32.
Answer:
The confidence interval is -5.3444 to 6.453 .
Step-by-step explanation:
We are given that In a survey of 458 likely voters, 254 said that they would vote "yes" on the referendum.
So, n = 458
x = 254
We will use sample proportion over here
Confidence level = 95% = 0.95
Level of significance = 1-0.95 = 0.05
z value at 0.05 significance level = 1.96
Formula of confidence interval : 
to 
Confidence interval : 
to 
Confidence interval : 
to 
Hence The confidence interval is -5.3444 to 6.453 .
Answer: 112.5%
