Answer:
1 no
2 no
3 no
4 yes
5 no
Step-by-step explanation:
we know that
<u>1) If the line segment AB is parallel to the line segment DC</u>
then
m∠1=m∠D -------> by corresponding angles
<u>2) If the line segment AD is parallel to the line segment BC</u>
then
m∠3=m∠B -------> by corresponding angles
ΔACB and ΔMNB are similar. Therefore the corresponding sides are in proportion:
Substitute:
Ok so let me help you like this: We need to understand first that <span>The basketball has a higher speed, that means that the tennis ball will never catch up. so what we need to use is the formula
</span>Vr=Vb--Vt
<span>=0.5-0.25=0.25
</span>So the speed is <span>0.25m/s
Hope this is useful</span>
Answer:
d. There is a 98% chance that the true proportion of customers who click on ads on their smartphones is between 0.56 and 0.62.
Step-by-step explanation:
Confidence interval:
x% confidence
Of a sample
Between a and b.
Interpretation: We are x% sure(or there is a x% probability/chance) that the population mean is between a and b.
In this question:
I suppose(due to the options) there was a small typing mistake, and we have a 98% confidence interval between 0.56 and 0.62.
Interpreation: We are 98% sure, or there is a 98% chance, that the true population proportion of customers who click on ads on their smartphones is between 0.56 and 0.62. Option d.
