Jordan spent a total of $14.85 on a trip to the zoo. She spent $6.50 to get into the zoo, $2.85 on snacks, and the rest on bus fares. How much did she spend on bus fares to and from the zoo? A) $5.05 B $5.50 C $8.35 D $9.35 . museum announces that it has just
Answer:
To find your answer you would subtract $6.50 and $2.85 from $14.85
you would get $5.50 so that is how much she spent on a round trip ticket to the zoo.
Step-by-step explanation:
El espesor de un borde de un componente de una aeronave está distribuido de manera uniforme entre 0.05 y 1.05 milimetros.Obtenga la función de distribución acumulada del espesor del borde.Calcule la proporción de bordes cuyo espesor es mayor que 1.02 milimetros.Qué espesor estEa excedido por el 90% de los bordes.Calcule la media y la varianza del espesor.
Answer:
a) [tex]F(x)\begin{cases} & 0\text{ if } x \leq 0.05 \\ \\ &\dfrac{x - 0.05}{1.05 - 0.05} = x - 0.05 \text{ if } 0.05 \leq x \leq 1.05 \\ \\ & 1 \text{ if } x \geq 1.05 \end{cases}[/tex]
b) 0.03
c) 0.15
d) La media es 0.55
La varianza es 8.[tex]\overline 3[/tex]
Step-by-step explanation:
La variación del espesor del componente de la aeronave = 0.05 a 1.05
El pdf de la variable 'X' se da de la siguiente manera;
[tex]f(x) = \dfrac{1}{1.05 - 0.05} = 1[/tex] por 0.05 < x < 1.05
a)
[tex]F(x)\begin{cases} & 0\text{ si } x \leq 0.05 \\ \\ &\dfrac{x - 0.05}{1.05 - 0.05} = x - 0.05 \text{ si } 0.05 \leq x \leq 1.05 \\ \\ & 1 \text{ si } x \geq 1.05 \end{cases}[/tex]
b) Para la proporción de los bordes que con un espesor superior a 1.02 milímetros, obtenemos;
P(X > 1.02) = 1 - F(1.02) = 1 - (1.02 - 0.05) = 0.03
P(X > 1.02) = 0.03
La proporción de bordes que tienen un espesor mayor que 1.02 = 0.03
c) El espesor, 'x', excedido en el 90% de los bordes, se encuentra de la siguiente manera;
P(X > x) = 1 - F(x)
∴ 90/100 = 0.9 = 1 - F(x) = 1 - (x - 0.05)
x - 0.05 = 1 - 0.9 = 0.1
x = 0.1 + 0.05 = 0.15
∴ El espesor excedido en el 90% de los bordes, x = 0.15
d) Para una variable aleatoria uniforme continua, a ≤ x ≤ b, tenemos;
[tex]El \ significado, \mu = E(X) = \dfrac{(a + b)}{2}[/tex]
[tex]La \ varianza, \sigma^2 = V(X) = \dfrac{(b - a)^2}{12}[/tex]
Para la distribución de espesor de borde dada, tenemos;
0.05 < x < 1.05
[tex]\therefore El \ significado, \mu = E(X) = \dfrac{(0.05 + 1.05)}{2} = 0.55[/tex]
El significado E(X) = 0.55
[tex]La \ varianza, \sigma^2 = V(X) = \dfrac{(1.05 - 0.05)^2}{12} = 1/12 = 8.\overline 3[/tex]
La varianza, V(X) = 8.[tex]\overline 3[/tex]
Simplify the product. Write your answer in standard notation 2y(5y^2 + 3)
Answer:
10y^3+6y
Step-by-step explanation:
Given that events A and B are independent with P(A)=0.34P(A)=0.34 and P(A\text{ and }B)=0.034P(A and B)=0.034, determine the value of P(B)P(B), rounding to the nearest thousandth, if necessary.
Answer:
0.1
Step-by-step explanation:
If A and B are independent, hence P(A and B) = P(A)P(B)
Given the following
P(A and B) = 0.034
P(A) = 0.34
Required
P(B)
Substitute into the given formula;
P(B) =P(A and B)/P(A)
P(B) = 0.034/0.34
P(B) = 0.1
Hence the value of P(B) is 0.1

These triangles are similar and the sides are proportional. Which proportion correctly describes the situation below?
Answer:
Option (3)
Step-by-step explanation:
"If two triangles are similar, their corresponding sides are proportional."
We will check each proportionality ratio given in the options for the given property,
Option (1),
[tex]\frac{QB}{DM}=\frac{DF}{QL}=\frac{LB}{MF}[/tex]
[tex]\frac{3.5}{2}=\frac{5}{8.75}=\frac{10.5}{6}[/tex]
[tex]\frac{7}{4}=\frac{4}{7}=\frac{7}{4}[/tex]
But [tex]\frac{7}{4}\neq \frac{4}{7}[/tex].
Therefore, this option is not the answer.
Option (2),
[tex]\frac{FM}{LB}=\frac{BQ}{MD}=\frac{QL}{DF}[/tex]
[tex]\frac{6}{10.5}=\frac{3.5}{2}=\frac{8.75}{5}[/tex]
[tex]\frac{4}{7}=\frac{7}{4}=\frac{7}{4}[/tex]
But [tex]\frac{4}{7}\neq \frac{7}{4}[/tex],
Therefore, this option is not the option.
Option (3),
[tex]\frac{BQ}{MD}=\frac{QL}{DF}=\frac{BL}{MF}[/tex]
[tex]\frac{3.5}{2}=\frac{8.75}{5}=\frac{10.5}{6}[/tex]
[tex]\frac{7}{4}=\frac{7}{4}=\frac{7}{4}[/tex]
Therefore, this option is the answer.
Option (4),
[tex]\frac{6}{10.5}=\frac{2}{3.5}=\frac{5}{10.5}[/tex]
[tex]\frac{4}{7}=\frac{4}{7}=\frac{10}{21}[/tex]
But, [tex]\frac{4}{7}\neq \frac{10}{21}[/tex]
Therefore, this is not the correct option.

Answer:
Triangles ABC and ADC are congruent because they all have the same angles. AC bisects angle A which means that both triangles have the same angle measurement. C is a 180 degree angle and is bisected, meaning that both angles created are 90 degree angles and thus the same degree measurement.
Another reason why they are congruent is because the sides are equal. AB and AD are the same length because the picture shows a singular line on both sides meaning they are the same. The height of both triangles are the same because they share a height. BC and CD are the same length because AC is bisecting BD, meaning both sides are equal in length. Thus, both triangles have the same side measurements.
Answer:
yes it's all correct good luck
A sphere has radius 8 ft. If the radius is doubled, what is the effect on the volume?
The volume is multiplied by 6.
The volume is multiplied by 4.
The volume is multiplied by 8.
The volume is doubled.
Answer:
If the radius of the sphere is doubled, the volume would be multiplied by 4. Think of the sphere as a cube instead and if you were to double the sides, the area would be 4 times bigger. Hope this helps! :)

. Solve for x. a) 10 - 1/4x - 7 b) 3 (x + 8 ) = 21
a) 10 - 1/4x = 7
1/4x = 7 + 10
= 17
x = 17/ (1/4)
b) 3 (x + 8 ) = 21
x + 8 = 21/3
= 7
x = 7 - 8
= -1

find cot0 given cos0=2/7 and the terminal side is in quadrant IV
Answer:
0.2985
Step-by-step explanation:
find cot0 given cos0=2/7 and the terminal side is in quadrant IV
Given
cos theta = 2/7
theta = arccos(2/7)
theta = 73.40 degrees
cot theta = cot73.40
cot73.40 = 1/tan73.40
cot73.40 = 1/3.35
cot73.40 = 0.2985
hence the required answer is 0.2985

Answer:
B
Step-by-step explanation:
its a right angle and one point is 40 as shown already so 90-40=50 hope this helps
So you would take your 90° angle which is the box on the bottom right hand corner and add 40° which would equal 130° and then you would subtract 180° -130° and you would get 50°.

Step-by-step explanation:
f(3) this one we use the second question (because the value that x is equal to is between 0 and 4)
3²+1=10
f(6) = -1 because this value is greater than 4
because the second equation has 0 inclusive we use this one for f(0)
