2) The base of a regular pyramid is a hexagon. What is the area of the base of the pyramid?
[area of the base}=[area of hexagon]
[area of hexagon]=6*[area of triangle]
area of triangle
sin 60=a/14-------> a=(√3/2)*14-------> a=7√3 cm
cos 60=(b/2)/14--------> (b/2)=cos 60*14-----> (1/2)*14---------> (b/2)=7
base of triangle=2*7--------> b=14 cm
[area of triangle]=14*7√3 /2--------> 49√3 cm²
so
[area of hexagon]=6*[49√3]--------> 294√3 cm²

Joe has a bag of marbles. There are 2 purple, 1 red, and 3 green marbles in the bag. Joe selects a marble, does not replace it before selecting a second marble. What is the probability that Joe will select a green marble, then a red marble?
Answers
Answer:
1/10
Step-by-step explanation:
There are 6 marbles in the bag. 3 out of 6 are green.
3/6 = 1/2
So, he has a 1/2 of picking a green marble.
After getting a green marble, Joe doesn’t replace it meaning there are now only 5 marbles in the bag.
Since there’s one red marble in the bag the chance of trying one is 1/5.
Now to find the chance or drawing a green and red marble you need to do the equation:
1/2 x 1/5
This equals 1/10.
The probability is 1/10

The product of two consecutive positive even integers is 14 more than their sum. Set up an equation that can
used to find the two numbers and solve it.
Answers
Answer:
+/- 2 both work.
Step-by-step explanation:
Remark
To make sure they are even, you need to use 2x and 2x + 2
Equation
2x (2x + 2) = 2x + 2x + 2 + 14 Combine like terms on the right
Solution
2x(2x + 2) = 4x + 16 Remove the brackets
4x^2 + 4x = 4x + 16 Subtract 4x from both sides.
-4x -4x
4x^2 = 16 Divide by 4
x^2 = 16/4
x^2 = 4 Take the square root of both sides
x = +/- 2
Question
Does - 2 work?
2(-2)(-2*2 + 2) = 4(-2)+2 + 14
-4(-4 + 2) = - 8 +2+ 14
-4( - 2) = - 8 + 2+ 14
8 = 8
Yes it does
This question confuses me, and I am not understanding it.
Answers
Answer: As n increases, p increases.
The question is asking you about the equation of a line, p=2n-10
The equation of a line is y=mx+b
In this equation, m is the slope (how much you go up or down and then over)
In this equation, b is the y-intercept (where it intersects with the y line at 0)
Now with this knowledge, p=2n-10
P stands for y and N stands for x (its the same thing even if different)
2n means the m=2
Since the slope is positve it goes up 2 and then right 1
The y-int is -10
Now the options want to know what happens as n increases
Since the slope is positive when the x increases you know that the y increases so
As n increases, p increases.
(also i attached what the graph looks like)
I hope this explanation could help, please let me know if you do not understand still and if you could mark brainliest I would greatly appreciate it.

B. 46x + 25
C. 50x + 11
D. 64x + 24
Answers
Answer:
the answer is c 50x +11
Step-by-step explanation:
The Perimeter of the model is (50x + 11).
What is Perimeter?A shape's perimeter is calculated mathematically using the idea of perimeter. You sum together the lengths of all the sides to find the perimeter.
We have,
The two sides of the triangle are 6x - 4 units each.
The length of the rectangle is 14x + 13.
The width of the rectangle is 12x + 3.
So, the perimeter of the house
= (6x -4) + (14x + 13) + (12x + 3) + 12x + 3 + 6x -4
= 50x + 11
Thus, the perimeter is 50x + 11.

Beetles may be the most varied order of animals. New beetle species are authenticated, completely unpredictably, at a typical rate of one every 7.0 months. A supplement to a guide is planned to be published after 20 new species have been discovered. a) What are the expected value and standard deviation of the number of months (treated as a continuous measure of time) until the supplement is published
Answers
Answer:
The mean until the supplement is published is 140 months, while the standard deviation is of 11.8 months.
Step-by-step explanation:
The Poisson distribution is used to solve this question, as we have only the mean. In this distribution, the standard deviation is the square root of the mean.
In this question, we have that:
Species are discovered at a rate of once every 7 months.
A supplement to a guide is planned to be published after 20 new species have been discovered.
a) What are the expected value and standard deviation of the number of months (treated as a continuous measure of time) until the supplement is published?
Mean is: 7*20 = 140 months.
Standard deviation is [tex]\sqrt{140}[/tex] = 11.8 months.
The mean until the supplement is published is 140 months, while the standard deviation is of 11.8 months.

Question A researcher wants a 30 milliliter acid solution with a concentration of 8%. She has concentrations of 2% and 11%. How much of each solution must she use to get the desired concentration?
Answers
Answer:
The researcher needs 20 milliliters of 11 percent concentrated acid and 10 milliliters of 2 percent concentrated acid.
Step-by-step explanation:
Given that a researcher wants a 30 milliliter acid solution with a concentration of 8%, and she has concentrations of 2% and 11%, to determine how much of each solution must she use to get the desired concentration, the following calculation must be performed:
100 x 0.11 + 0 x 0.02 = 11
90 x 0.11 + 10 x 0.02 = 10.1
80 x 0.11 + 20 x 0.02 = 9.2
70 x 0.11 + 30 x 0.02 = 8.3
66.666 x 0.11 + 33.333 x 0.02 = 8
30 x 0.6666 = 20
Therefore, the researcher needs 20 milliliters of 11 percent concentrated acid and 10 milliliters of 2 percent concentrated acid.

The fractions are: 1/7, 3/16, 5/19, 1/4, 9/28. if simplified, then these are different fractions.
Additionally, you can see that it has both 5/19 and 5/20. (1/4).
If this was a working function it would yield the same output every time you put in 5 as an input.
Therefore, it cannot represent a function.
