Given a normal distribution of the lengths of wing-spans of a certain butterfly has a mean of 20 mm and standard deviation 3.5 mm. Find, ROUNDING YOUR ANSWERS TO 4 DECIMAL PLACES. A) What wing-span has an area of 0.1005 on it left side under the standard normal curve? B) What wing-span has an area of 0.0480 on it right side under the standard normal curve?
Answer:
a) 15.52mm
b) 25.8275mm
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X, or the area to the left side of the curve. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X, that is, the area to the right side of the curve.
A) What wing-span has an area of 0.1005 on it left side under the standard normal curve?
This is X when Z has a pvalue of 0.1005. So it is X when Z = -1.28.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.28 = \frac{X - 20}{3.5}[/tex]
[tex]X - 20 = -1.28*3.5[/tex]
[tex]X = 15.52[/tex]
This wing-span is 15.52mm.
B) What wing-span has an area of 0.0480 on it right side under the standard normal curve?
This is X when Z has a pvalue of 1 - 0.0480 = 0.9520. So this is X when Z = 1.665.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.665 = \frac{X - 20}{3.5}[/tex]
[tex]X - 20 = 1.665*3.5[/tex]
[tex]X = 25.8275[/tex]
This wing-span is 25.8275mm.

Running from the top of a flagpole to a hook in the ground there is a rope that is 13 meters long. If the hook is 5 meters from the flagpole, how tall is the flagpole?
Answer:
12 meters
Step-by-step explanation:
Looking at the problem we can see that it typifies a right angled triangle. The rope running from the top of the flagpole to the hook on the ground is the hypotenuse of the triangle. Let us call this hypotenuse c. Let the distance between the hook and the foot of the flagpole be b. Let the height of the flagpole be a.
From Pythagoras theorem;
c^2 = a^2 + b^2
a^2= c^2 - b^2
a= √c^2-b^2
From the question
c= 13 metres
b= 5 metres
a= the unknown
a= √c^2-b^2
a= √(13)^2 - (5)^2
a= √169 - 25
a= √144
a= 12 meters
Answer:
The flagpole 12 meters tall
Step-by-step explanation:
Running from the top of a flagpole to a hook in the ground there is a rope that is 13 meters long
∵ The hook is 5 meters from the flag pole
∵ The flagpole and the ground ⊥ to each other
By using Pythagoras theorem:
hypothenus side is 13m
base is 5m
how tall is the flagpole is x
[tex]13^2=x^2+5^2\\\\169=x^2+25\\\\x^2=169-25\\\\x^2=144\\\\x=12m[/tex]
The flagpole 12 meters tall

Given r,s,t are midpoints of AC,AB, and CB use the figure below to complete the following problem
Answer:
The first option, RT.
Step-by-step explanation:
I have been asking for assistance for an hour and a half now, I will greaty appreciate anyone that can help with this..Find the Slopes,and for the third one find Mid-point
Answer:
1st graph: m = -1/2. (m is the slope)
2nd graph: m = 3/2.
3rd graph: Midpoint = (1/2, 1/2)
Step-by-step explanation:
1st graph:
Find the slope by looking for two points on the line. Use the formula [tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
We can derive the points (-3, 0) and (1, -2). Plug these into the equation above.
[tex]m= \frac{-2-0}{1-(-3)}[/tex]
Simplify this, giving you: m = -1/2.
2nd graph:
Use the same formula as stated above. From this graph, you can plug in the points (-1, 1) and (1, 4)
[tex]m = \frac{4-1}{1-(-1)}[/tex]
Simplifying gets you: m = 3/2.
3rd graph:
To find the midpoint, use the formula: [tex](\frac{x_{1}+x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )[/tex]
Plug in the end-points of the graph, or (-3, 2) and (4, -1).
You get:
[tex](\frac{-3+4}{2}, \frac{2-1}{2})[/tex]
Simplify:
Midpoint = (1/2, 1/2)
RESUELVE EL SIGUINTE PORBLEMA En la escuela "Soy Feliz porque soy diverso", hay 230 estudiantes en total. De estos, 35 son mujeres. a) ¿Cuántos son hombres? b) ¿Qué parte del total de los estudiantes son hombres? 2. María se ha gastado 13 del dinero que le dieron de paga sus abuelitos en comprar un libro de aventuras. También se ha gastado 29 de la paga en comprar una cartuchera. ¿Qué fracción de su paga se ha gastado María? Datos: Libro de aventuras = 13 Cartuchera = 29 Solución: 13+ 29=3+29= 59
Answer:
1) a. 195 are males
b. Males are the 85 %
2) 1/2
Step-by-step explanation:
Number of all the students: 230
35 are females
x are males
Then 35 + x = 230
x = 230 - 35 → 195
To determine the amount of males, from the total we apply the percent.
Percent = (Amount of males / Total of students) . 100
% = (195 / 230) . 100 = 85 %
2. In first place, Maria spent 13 for the book.
In second place, Maria spent 29 for the pencil box.
In total, she has spent 13+29 = 42
But, how many dolars have the grandpa gave to her?.
We can also apply percent and fractions, where:
(Book / Total) + (Pencil box/Total) + (What she did not spend/Total) = 1
13 + 29 + x = T
13/T + 29/T + x/T = 1, in conclussion x = 42
Total of money given = 84
Then, Maria has not spent the half of money→ 1/2

c) (1, 8, 27, 64, ...) Recursivo
d) (2, 5, 8, 11, 14, 17, ...) Recursivo
Step-by-step explanation:
Uma função recursiva é aquela em que os termos subsequentes da função são calculados com base nos termos anteriores
O comportamento recursivo é exibido pelos objetos quando consiste em seguir as partes;
1) Uma base que é predefinida
2) Um processo ou etapa recursiva que produz termos subsequentes pela aplicação de certos processos
Para a série;
a) (5, 7, 9, 11, 13, 15, 17, 19, ...)
Aqui 5 é a base e os termos subsequentes são encontrados adicionando 2 ao termo anterior, portanto, é uma função recursiva
aₙ = aₙ₋₁ + 2
b) (1, 4, 9, 16, 25, 36, 49, 64, ...)
Aqui 1 é a base e os termos subsequentes são encontrados ao quadrado da soma da raiz do termo anterior e 1, portanto, é uma função recursiva
aₙ = (√ (aₙ₋₁) + 1) ²
c) (1, 8, 27, 64, ...)
Aqui 1 é a base e os termos subsequentes são encontrados elevando à potência de três a soma da raiz cúbica do termo anterior e 1, portanto, é uma função recursiva
aₙ = (∛ (aₙ₋₁) + 1) ³
d) (2, 5, 8, 11, 14, 17, ...)
Aqui 2 é a base e os termos subsequentes são encontrados adicionando 3 ao termo anterior, portanto, é uma função recursiva.

A focus group is made up 12 males and 4 females. Half of the males have college degrees. A member is selected at random from the geoup. What is the probability that the member is a male with a college degree?
Answer:
3/8
Step-by-step explanation:
We first have to find the probability that the person selected is a male and then multiply that by the probability that the male has a college degree.
There are 12 males and 4 females. There are 16 people in total. The probability of selecting a male is:
12/16 = 3/4
Half of the males have a college degree. Therefore, 6 males have a college degree. The probability that a selected male has a college degree is:
6/12 = 1/2
Therefore, the probability that a male is selected and that the male has a college degree is:
3/4 * 1/2 = 3/8

Point A lies on the circle and has an x-coordinate of 1.
Which is the correct calculation of the y-coordinate of point A?
Answer:
y=0
correct way to solve it is y= xtan(theta)
Step-by-step explanation:
You did not mention if it is trigonometry but we assume that it is.
In trigonometry, a point with x-coordinate = 1 at a circle is horizontal line. the angle at this point is 0.
The correct way to solve it is to say tan = opposite/adjacent
since the angle is zero, and adjacent side x=0, tan 0=opposite/1
opposite (y) = 1 tan 0
y = 1*0 =0

e(t) = 840 – 52.51
meters from the ground
minutes after it
Since e(14) = , the elevation of the cable car will be
from the top of the hill,
Corrected Question
e(x)=840-52.5x
Let e(x) be the elevation, in meters, of a cable car from the ground, x minutes after it begins descending from the top of a hill. Since e(14) = ?, the elevation of the cable car will be meters from the ground minutes after it begins descending from the top of the hill.
Answer:
e(14) =105 meters
Elevation of the cable car 14 minutes after it begins descending from the top of the hill= 105 meters from the ground
Step-by-step explanation:
Given the elevation, e(x) in meters, of a cable car from the ground , x minutes after it begins descending from the top of a hill.
e(x)=840-52.5x
e(14)=840-52.5(14)
e(14)=840-735
e(14)=105 meters
Since e(14) =105 meters, the elevation of the cable car will be 105 meters from the ground 14 minutes after it begins descending from the top of the hill.
If v varies directly as w, and v=24 when w=8, find the equation that relates v and w.
Answer:
v = 3w
Step-by-step explanation:
Given that
v ∝ w
The, v = k w ---------------(1)
Where k is the constant of proportionality
Now, v = 24, w = 8
Putting in (1)
24 = k(8)
Dividing both sides by 8, we get
k = 3
Putting k =3 in (1)
v = 3w
This is the required equation connecting both

Answer:
120
Step-by-step explanation:
The sum of the angles in a quadrilateral is 360 degrees
2t+t+2t+t = 360
6t = 360
Divide by 6
6t/6 = 360/6
t = 60
Angle Z = 2t
Angle Z = 2*60 = 120
Answer:
[tex]120 \: \: degrees[/tex]
Second answer is correct.
Step-by-step explanation:
The sum of the angles in a qudrilateral = 360°
[tex]t + 2t + t + 2t = 360 \\ 6t = 360 \\ \frac{6t}{6} = \frac{360}{6} \\ t = 60[/tex]
angle z
[tex]2t = 60 \times 2 \\ \: \: \: \: \: \: \: = 120[/tex]
A box contains 56 balls. The probability of selecting a red ball at random is 5/7. How many balls in the box are not red?
Answer:
Brain to me plz
Step-by-step explanation:
2/7 is the balls are not red, so 2/7 multiplyed by 56
which is 16
Answer:
16 balls
Step-by-step explanation:
If 5/7 of the balls are red then the fraction of balls that are not red is;
[tex]\frac{7}{7} - \frac{5}{7} = \frac{2}{7}[/tex]
Which means 2/7 of the balls are not red. So to get the number;
[tex]= \frac{2}{7} * 56 \\= 2 * 8\\[/tex]
= 16
∴16 balls are not red
Two bags contain coloured cubes.
Bag 1 has 3 red cubes and 1 blue cube.
Bag 2 has 3 green cubes, 1 yellow cube, and 1 red cube.
Is the probability that you will get a red cube from Bag 1 and the yellow cube from Bag 2 more or less than the probability of getting the blue cube from Bag 1 and a green cube from Bag 2? Explain.
Answer:
equal
Step-by-step explanation:
Bag 1 has 3 red cubes and 1 blue cube. = 4 cubes
Bag 2 has 3 green cubes, 1 yellow cube, and 1 red cube.= 5 cubes
P ( red bag 1) = red /total = 3/4
P (yellow bag 2) = yellow /total = 1/5
P(red bag1 , yellow bag2) = 3/4* 1/5 = 3/20
P ( blue bag 1) =blue /total =1/4
P (green bag 2) = green /total = 3/5
P(blue bag1 , green bag2) = 1/4* 3/5 = 3/20
The probabilities are equal
Now look at this information
[tex]2y + 3 \leqslant 11[/tex]
What is the largest value that y could be?
Answer:
4
Step-by-step explanation:
Given
2y + 3 ≤ 11 ( subtract 3 from both sides )
2y ≤ 8 ( divide both sides by 2 )
y ≤ 4
Since y has to be less than or equal to 4
Then the largest value y could be is 4
A line passes through (-1,7) and (2,10) which answer is the equation of the line
Answer: -x + y = 8
Step-by-step explanation:
So first you are going to want to find the slope of the equation. The equation for that it (y2 - y1)/(x2 - x1) = (10 - 7)/(2 - -1) and that equals 1. So your slope will be 1.
Now you have half of your equation complete, currently it looks like, y = x + b. So we have to find the y intercept. You can do that by plugging in a pair of coordinates into the current equation and solve for b.
Lets plug in (2,10)
10 = 2 + b
10 - 2 = b
b = 8
So now you have your equation in slope intercept form, y = x + 8. Just move the x over to the left side and there is your answer.
-x + y = 8
