animals are in the zoo?
A: 13
B: 130
C: 260
D: 325
Step by step explanation please!
Answers
Answer:
d. 325
If 20 percent of the animals are amphibians and yiu are trying to find the total amound of numbers in the zoo you first have to realize that 20% is equal to 1/5. Then since you are trying to find the total and not decrease the number, you get the reciprical of 1\5, which is 5/1 and multiply it by 65/1 . 5 × 65 equals 325.

Step-by-step explanation:
Using the tangent ratio in the right triangle
tan G = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{HI}{GI}[/tex] = [tex]\frac{1.1}{7.5}[/tex] , then
∠ G = [tex]tan^{-1}[/tex] ([tex]\frac{1.1}{7.5}[/tex] ) ≈ 8.3° ( to the nearest tenth )

A store manager claims that 60% of shoppers who enter her store make a purchase. To investigate this claim, she selects a random sample of 40 customers and finds that 40% of them make a purchase. She wants to know if the data provide convincing evidence that the true proportion of all customers who enter her store that will make a purchase differs from 60%. The P-value of this test is 0.0098. Interpret the P-value.
Assuming the true population proportion of shoppers who will make a purchase is 0.60, the probability of obtaining a sample statistic of 0.40 in a random sample of 40 customers is 0.0098.

I do believe that it is Option B
(Assuming the true population proportion of shoppers who will make a purchase differs from 0.60, the probability of obtaining a sample statistic of 0.40 in a random sample of 40 customers is 0.0098.)
Step-by-step explanation:
This sample provide evidence that the grocery store manager overstated the true proportion P-value = 0.0333.
What is p-value?In null-hypothesis significance testing, the p-value is the probability of obtaining test results at least as extreme as the result actually observed, under the assumption that the null hypothesis is correct.
here, we have,
Given data in the question:
To test whether population proportion p is overstated;
Null hypothesis H₀ : p = (75%) = 0.75
Alternative hypothesis H₁ : = < (75%) < 0.75
Now, sample proportion p" = 64 / 100 = 0.64
From the dot plot below,
we will determine the p-value for test { P(p" < 0.64)}
The number of times p"<0.64 in 150 simulations is 5
Therefore:
P(p" < 0.64 ) = 5 / 150 = 0.0333
P-value = 0.0333
At 5% level of significance;
0.0333 < 0.05
Therefore, we reject null hypothesis H₀ at 5% level of significance,

Is a triangle with sides measuring 9 feet, 12 feet, and 18 feet a right triangle?
If you give a link, fake answer, or using for points will be reported.
Answers
Answer:
No, because the Pythagorean theorem does not prove it to be a right triangle
Step-by-step explanation:
is 9² + 12² = 18²?
81 + 144 ≠ 324
Explanation:
Using the Converse of the Pythagorean Theorem which is in square length of the longest side is equal to sum of the square lengths of the other to sides, then the triangle is a right triangle.
So, you make an equation were the longest side (18 in this problem) equals the other two sides (9 and 12).
So the equation would look like:
18^2=9^2+12^2
Then you would solve for each number squared and end up with:
324=81+144
Solve:
324=225
Since the equation is false this is not a right triangle, but according to the obtuse triangle inequality theorem which is if the square length of the longest side is greater than the square length of the other side sides then the triangle is an obtuse triangle. So, this triangle is not a right triangle but an obtuse triangle.

The value of y for the given circle will be 54°.
What is a circle?A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.
The diameter is the longest line that can be drawn inside a circle.
In our daily life, we always see circle objects for example our bike wheel.
Area of circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.
In the given question by the circle theorem that if a curve makes a 2x angle then the extreme point will make the angle on circle as x.
So angle y = half of angle 108°
∠Y = 108°/2 = 54°
Angle w will also same as 54° because it also satisfies the theorem of the circle.

Step-by-step explanation:
4(x-3)^2 = 80
4x-12^2= 80 --- (distribute)
4x+144= 80 --- ( why a positive 144 because a (-) * a (-) = a (+)
4x = (80-144) --- ( subtract -144 from +144(do it on both sides)
4x = -64 --- (divide both sides by 4)
x= -16
Answer:
2√5 +3
Step-by-step explanation:
Isolate x:
4(x-3)^2 = 80
Divide both sides by 4.
(x-3)^2 = 20
Then take the square root of each side.
(x-3) = √20
Add 3 to each side.
x = √20 + 3
√20 can be rewritten as 2√5.
x = 2√5 + 3
The model represents an inequality. what is the solution set for the inequality?
Answers
Answer:
Then the solution set is all the values of x equal to or larger than -3.
Step-by-step explanation:
First, we know that each long strip represents an x.
Each white square represents 1.
Each grey square represents -1
Then, at the left side, we have:
8 long stripes.
12 white squares
Then we can write that as:
8*x + 12*1 ≥
And in the right side, we have 12 grey squares, then that is:
≥ 12*-1 = -12
Then the inequality is:
8*x + 12 ≥ -12
To find the solution set, we just need to isolate x.
First, we can subtract 12 in both sides to get:
8*x + 12 - 12 ≥ -12 - 12
8*x ≥ -24
Now we can divide both sides by 8
8*x/8 ≥ -24/8
x ≥ -3
Then the solution set is all the values of x equal to or larger than -3.

-2 - 4 = -6
4 + 4 = 8
-6 ÷ 8 = [tex]-\frac{3}{4}[/tex]
The slope of a line perpendicular to another line is the opposite reciprocal of the given slope.
The opposite reciprocal of [tex]-\frac{3}{4}[/tex] is [tex]\frac{4}{3}[/tex]
So now all we need to finish the slope intercept form y = mx + b is b, which is the y intercept.
