Hi there,
I believe there are 3 questions.
- 2+5=8-1 It is true because 2+5 is 7 and 8-1 is 7. So, both sides have same value which means they are equal.
- 4+2=9-1 It is false because 4+2 is 6 and 9-1 is 8. So, the values are different.
- 13-0=12+1 It is true because 13-0 is 13 and 12+1 is 13. Both values are same. Therefore, they are equal.
Hope it helps :-)
Answer:
Your answer would be 16 - 7 = 9.
You can simply add the two numbers and it would still give you the same answer, but I decided to just look for the number.
Step-by-step explanation:
I hope this helped solve your question.
Answer:
Step-by-step explanation:
Let us find the acceleration of box .
v² = u² + 2as
Putting the values
7² = 3² + 2 a x 14
a = 1.43 m /s²
If coefficient of friction be μ
force of friction = μ mg
= μ x 10 x 9.8
= 98μ
Net force pushing the box
= 85 - 98μ
Applying newton's second law
85 - 98μ = 10 x 1.43
98μ = 85 - 14.3
μ = .72
Answer:
<u>Use Two sided t-test</u>
<u>Step-by-step explanation:</u>
Note that, there are other tools to test for significant difference such as simple regression or multiple regression<em> but when comparing the results of two groups in terms of which is higher or lower</em>, then a two sided t-test would be best appropriate.
Since we want to know if there is a significant difference between the number of tornadoes in August and the number of tornadoes in October on average we use the two sided t-test because a Two sided t-test can show the possibility of positive or negative differences.
You would take 6.4% into 1640000 and you would pay that the next 30 years
