Yes they are
. 90/150= 3/5
so 45/75 and 3/5.
Answer:
For this case the parameter of interest is given by:
who represent the true proportion of respondents said that they were willing to pay more for products and services from companies who are committed to positive social and environmental impact
For this case we have an estimation given for this parameter. The estimation comes from a sample of 30000 people selected in 60 countries and they got:

This value represent the best estimator for the true proportion since is an unbiased estimator of the real parameter:

Step-by-step explanation:

For this case if we want to test if the population proportion is equal to an specified value we can use the one sample z test for a proportion:
Null hypothesis:
Alternative hypothesis:
When we conduct a proportion test we need to use the z statisitc, and the is given by:
(1)
The One-Sample Proportion Test is used to assess whether a population proportion
is significantly different from a hypothesized value

Algebra
Use the distributive property to make 5x+5.
5x+5<25
Subtract 5 from both sides.
5x<20
Divide both sides by five.
x<4
<span>the train cannot exceed a length of 1100 feet
Now, train A = 28 cars at 30 feet each
Therefore, Train A's total length = 28*30 = 840 feet < 1100 feet.
</span>Now, train B = 22 cars at 40 feet each
Therefore, Train B's total length = 22*40 = 880 feet < 1100 feet.
Thus, both the <span>trains meet the requirement. </span>
