Obviously if it takes him around 12 hours to drive 1158 km. Then by ratio method we can calculate how much time it takes for him for one hour. So 1158/12 = 96.5 in one hour.
Now for the next part we can see he drove around 484 after 5 hours. So we can see his average of 1 hour by 484/5 = 96.8 so according to this pace he might arrive a little before time.
Answer:
84 m² is the correct answer.
Step-by-step explanation:
first, split the parallelogram into three shapes: the two triangles on either side of the shape, and the rectangle in the middle.
the formula for the area of a triangle is base x height / 2. all of the measures are indicated in the picture so that means that 4 x 7 / 2 = 14. since there are two triangles, add 14 + 14 = 28.
then, find the area of the rectangle. the area of a rectangle is length x width. 8 x 7 = 56.
56 + 28 = 84.
Answer:
the 3rd one
Step-by-step explanation:
It would be 120 because 4% of 125 is 5, so you subtract 5 from 125 to get 120. I am pretty sure that's how you do it
Using the z-distribution, the 95% confidence interval for the proportion is given as follows:
(0.4576, 0.5824).
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:
In which:
is the sample proportion.
In this problem, we have a 95% confidence level, hence
, z is the value of Z that has a p-value of 
, so the critical value is z = 1.96.
The other parameters for the interval are given as follows:
.
The lower and upper bound of the interval, respectively, are given by:
