Let
p---------------> is the perimeter of the base
s--------------> is the slant height
ba-----------> is the area of the base
la-----------> is the lateral area
we know that
[surface area of the pyramid]=area of the base+perimeter of the base*slant height/2
so
[surface area of the pyramid]=ba+p*s/2
la=p*s/2
[surface area of the pyramid]=ba+la
the answer is
surface area=ba+p*s/2
surface area=ba+la

4. More people bought 1 cupcake than any other number of cupcakes is the true statement.
Explanation;
- First, we need to understand what each statement means and check if it's right by checking with the dot plot.
- Statement 1; Every person bought at least one cupcake. This is not true as 2 people who did not buy any cupcakes at all. So statement 1 is not true.
- Statement 2; The most cupcakes a person bought was 8. According to the dot plot, the most cupcakes bought by a person were 5 so statement 2 is incorrect.
- Statement 3; Every person bought between 1 and 5 cupcakes. As said for statement 1 not everyone who came bought a cupcake so statement 3 is incorrect.
- Statement 4; More people bought 1 cupcake than any other number of cupcakes. According to the dot plot, 8 people bought 1 cupcake and no other number of cupcakes were bought as much. So this is the right statement.
Answer:
The answer: cougar population is 9 times the bear population
Step-by-step explanation:
∵ x = 15 ⇒ 15 years after study time
∵ f(x) = 830(0.8)^15 = 29.203 ≅ 29
From the table the cougar population after 15 years = 226
∴ The cougar population = 266 ÷ 29 = 9.172 ≅ 9 times the bear population
B would be the correct answer
