Answer:
B
Step-by-step explanation:
Overpopulation causes killing of animals
Answer:
B) An increase in biodiversity is good for the ecosystem because it provides a variety of species. Overpopulation is not good for the ecosystem because there are more individuals
Step-by-step explanation:
The bigger the ecosystem is, the more producers there are, which makes more consumers.
If there are too many consumers, then more populations will go extinct.

Find the length of c using the Pythagorean theorem
Answer:
13
Step-by-step explanation:
The Pythagorean theorem state
a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse
5^2 + 12^2 = c^2
25+144 = c^2
169 = c^2
Take the square root of each side
sqrt(169) = sqrt(c^2)
13 = c

What is an Inscribed Angle ?An inscribed angle in a circle is formed by two chords that have a common end point on the circle. This common end point is the vertex of the angle.
An inscribed angle in a circle is formed by two chords that have a common end point on the circle. This common end point is the vertex of the angle.
In the circle, the two lines AC and AD intersect outside the circle at the point A .
m∠CAE=1/2(m CD−m BE)
The formula for the angle between 2 secants is
1/2 (124 - 16)
= 1/2 * 108
= 54°
Therefore the measure of CA = 54°

Chloe breaks into the pantry after Albert goes to work. She finds and opens a family-pack of mixed nuts. After surfing the web, she finds that these packs claim to be 20% almond (A), 30% cashew (C), 10% macadamia (M), and 40% peanut. Chloe discovers that her bag contains 14 almonds, 28 cashews, 6 macadamias, and 52 peanuts.
a) Perform an appropriate test to determine whether this claim is true or not at a = 0.05. State all the relevant steps (listed in exercise 1).
b) What is the decision and conclusion (write a sentence) at a = 0.1?
c) Chloe is a choosy and sneaky doggie. She likes to find a p-value first and then come up with a significance level, a later so she can reject as many Hos as possible. Is her method acceptable?
Solution :
In this case we have to use [tex]$\text{chi square test}$[/tex] for the goodness of fit.
Null hypothesis is : [tex]$H_0 :$[/tex] Data follows the given distribution
Alternate hypothesis is : [tex]$H_a:$[/tex] Data do not follow the given distribution
The level of significance, [tex]$\alpha = 0.05$[/tex]
The test statistics is given by :
Chi square = [tex]$\sum\frac{(O-E)^2}{E}$[/tex]
Here O is the observed frequencies
E is the expected frequencies
So we have, N = number of the categories = 4
df = degrees o freedom = N - 1
= 4 - 1 = 3
Critical value = [tex]$7.814727764$[/tex]
Calculating the table for the test statistics are given as :
Category prop. O E [tex]$\frac{(O-E)^2}{E}$[/tex]
A 0.2 14 20 1.80
C 0.3 28 30 0.13
M 0.1 6 10 1.60
P 0.4 52 40 3.60
Total 1 100 100 7.13
The test statics = chi square = [tex]$\sum\frac{(O-E)^2}{E}$[/tex] = 7.13
[tex]$X^2$[/tex] statistics = 7.13
P-value = 0.067767248
P -value > [tex]$\alpha = 0.05$[/tex]
Therefore, we do not reject the [tex]$\text{null hypothesis}$[/tex]. There is sufficient evidence to conclude that the data follows the given distribution. So there is sufficient evidence to conclude the given claim is true.

Answer:
x = 11
Step-by-step explanation:
[tex]x-3y=-7[/tex]
[tex]5x=-2y+67[/tex]
=> [tex]x=\frac{1}{5}(-2y+67)[/tex]
=> [tex]x=-\frac{2}{5}y+\frac{67}{5}[/tex]
=> [tex]-\frac{2}{5}y+\frac{67}{5}-3y=-7[/tex]
=> [tex]-\frac{17}{5}y+\frac{67}{5} =-7[/tex]
=> [tex]\frac{-17}{5}y=-\frac{102}{5}[/tex]
=> y = 6
=> [tex]x=-\frac{2}{5} .6+\frac{67}{5}[/tex]

9. If NK = 7x-1, NM = 10x - 13, and KM = 24, find NP.
Answer:
[tex]NP = 24.18[/tex]
Step-by-step explanation:
Given
[tex]NK = 7x - 1[/tex]
[tex]NM = 10x - 13[/tex]
[tex]KM = 24[/tex]
See attachment
Required
Length of NP
First, calculate the value of x
[tex]NK = NM[/tex]
So:
[tex]7x -1 = 10x - 13[/tex]
Collect like terms
[tex]10x - 7x = 13 - 1[/tex]
[tex]3x =12[/tex]
Solve for x
[tex]x = 4[/tex]
To solve for NP, we consider right triangle [tex]\triangle NKP[/tex]
Where
[tex]NK = 7x - 1[/tex]
[tex]NK = 7 * 4 - 1[/tex]
[tex]NK = 27[/tex]
[tex]KP =\frac{1}{2}KM[/tex]
[tex]KP =\frac{1}{2} * 24[/tex]
[tex]KP =12\\[/tex]
Using Pythagoras theorem, we have:
[tex]NK^2 = KP^2 + NP^2[/tex]
[tex]27^2 = 12^2 + NP^2[/tex]
[tex]729 = 144 + NP^2[/tex]
Collect like terms
[tex]NP^2 = 729 - 144[/tex]
[tex]NP^2 = 585[/tex]
Take square roots
[tex]NP = \sqrt{585[/tex]
[tex]NP = 24.18[/tex]
in how many years 1600 invested at 5% will amount to 1920
Answer:
principal=1600
rate=5%
amount=1920
time=x
interest=p*t*r/100
=1600*x*5/100
=8000x/100
80x
amount=principal +interest
1920=1600+80x
1920-1600=80x
320/80=x
4=x
therefore after 5 years 1600 amount to 1920 at the rate of 5%
