Answer:
7.5 units squared
Step-by-step explanation:
Equation for solving the area is A = 1/2h(b1 + b2).
The bases here have a length of 4 and 1, so we add them together. The height is 3, so our equation is 1/2 * 3(5) = 7.5
Yes it is hl because thats what it is
Using the concepts of the mean and of the median, it is found that the correct option is given by:
both in the interval 6–10.
<h3>What are the mean and the median of the data-set?</h3>
- The mean is the <u>sum of all observations divided by the number of observations</u>.
- The median is the measure that separates the bottom half of the variable from the upper half, that is, the 50th percentile.
To calculate the mean from the histogram, we take the midpoint of each interval and calculate the weighed mean, hence:
The median is in the interval in which the 30/2 = 15th measure is, which is also in the interval 6-10, as the interval 1-5 had 14 adults, and after interval 6-10, there are 23 adults.
Hence, the correct option is given by:
both in the interval 6–10.

Answer: 175 robberies
Step-by-step explanation:
Robberies last year= 243
Robberies has reduced by 28% which means there are (100-28)% = 72% robberies this year.
Number of robberies this year= 72% of 243 = 72/100 × 243 = 174.96 = 175.
There are 175 robberies this year
Assuming it says form an equation it’s
2x +8.7 = 23.4
In that case he was thinking of the number 7.35
