x is equal to 5 and y is equal to 29
Answer:
5
Step-by-step explanation:
→ Let x = √20 + √20 .....
x
→ Square both sides
x² = 20 + √20 +√20 + √20
→ Replace √20 +√20 + √20 with x
x² = 20 + x
→ Move everything to the left hand side
x² - 20 - x = 0
→ Factorise
( x + 4 ) ( x - 5 )
→ Solve
x = -4 , 5
→ Discard negative result
x = 5
Answer:
-4432.5 m
Step-by-step explanation:
Displacement is measured in meters, so will be the product of velocity in m/s and time in s.
(-98.5 m/s)×(45.0 s) = -4432.5 m
___
If you're concerned with significant figures, you can round this to -4430 m, which has the required 3 significant figures.
Answer:
There is enough evidence at the 0.05 significance level that the percentage is less than 25%.
Step-by-step explanation:
<em>The question has no options. However, there are enough details to arrive at a conclusion.</em>
<em></em>
Required
What can we conclude about the claim of the publisher.
From the question, we understand that the null hypothesis is rejected.
In statistics, a hypothesis is rejected, if the level of significance is less than the required or determined value.
In this case, the determined value 25% and the level of significance is 0.05
<em>So, the conclusion on the claim is that there is enough evidence at the 0.05 significance level that the percentage is less than 25%.</em>
The distance between -182 and 265 is 83 because if you subtract 265 from-182 it will be 83. the answer is 83.
