Last week Cam's Ice Cream Shop sold 52 chocolate chip ice cream cones out of total of 997 ice cream cones. Based on this data, what is a reasonable estimate of the probability that the next ice cream cone sold is a chocolate chip ice cream cone?
Answer:
52/997
Step-by-step explanation:
YALL THIS IS CORRECT I PROMISE.
KHAN ACADEMY
The required probability of the next ice cream cone sold is a chocolate chip ice cream cone is 0.1.
Cam's Ice Cream Shop sold 52 chocolate chip ice cream cones out of a total of 997 ice cream cones. The probability that the next ice cream cone sold is a chocolate chip ice cream cone is to determine.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Cam's Ice Cream Shop sold 52 chocolate chip ice cream cones = 52
total of 997 ice cream cones = 997
The probability of the next ice cream cone sold being a chocolate chip ice cream cone = 52 / 997
= 0.1
Thus, the required probability of the next ice cream cone sold is a chocolate chip ice cream cone is 0.1.

Un par de zapatos más dos pantalones valen $ 70.000 en una tienda. Se ofrece una oferta, al comprar dos o más pares de zapatos del mismo precio se descuenta un 10% en cada par y por tres o más pantalones del mismo precio un 15% en cada pantalón. Juan paga por tres pantalones $ 38.250 y luego, compra dos pares de zapatos. ¿Cuánto pagó Juan por los dos pares de zapatos?
Answer:
49.5 $
Step-by-step explanation:
Comencemos por lo siguiente:
Si llamamos x al precio del par de zapatos y "y" al precio de cada pantalón, entonces la tienda ofrece:
un par de zapatos x más dos pantalones 2*y en 70.000 $ (deben ser 70 $ pero esa cifra no importa a los fines de resolver el problema, habrá solo que hacer el ajuste correspondiente, en lo que aqui respecta hablaremos de 70 $)
Entonces de acuerdo a lo expuesto
x + 2y = 70 or y = ( 70 - x) /2 (1)
Esa es la condición inicial.
Ahora bién Juan paga por tres pantalones 38.25 $
Eso quiere decir ( como los pantalones son iguales) que pago 38.25/3 por cada pantalón
38.25/3 = 12.75 $
Ahora bién ese precio tubo una rebaja del precio original del 15 % ( quiere decir que el precio original de cada pantalón es de
12.75/0.85 = 15 $ x = 15 $
Entonces si nos vamos a la ecuación (1) (alli los precios son originales) tenemos que
y = ( 70 - x ) / 2 y = ( 70 - 15 ) / 2 y = 55/2 y = 27.5 $
Ahora Juan paga por dos pares de zapatos donde según las ofertas de la tienda el debera tener un descuento del 10 % en cada par
Por lo que si un par cuesta 27.5 $ le darán un descuento del 10% es decir pagará 27.5 *0.9 = 24.75 por cada par, como son dos pares
pagará 2 * 24.75 = 49.5 $

Una recta pasa por los puntos A(-40) y B(2,-3).calcular su área
Answer:
Supongo que la pregunta completa es:
"Una recta pasa por los puntos A(-4, 0) y B(2, -3)"
Luego dice "calcular su área", pero una recta es un elemento unidimensional (los cuales no tienen área, el área es un concepto bidimensional).
Por lo que el área de esta recta no está definida.
Ignorando esto, podemos encontrar la ecuación que define a nuestra recta.
Sabemos que una recta se escribe como:
y = a*x + b
donde a es la pendiente y b es la ordenada al origen.
Sabemos que para una recta que pasa por los puntos (x₁, y₁) y (x₂, y₂), la pendiente será:
a = (y₂ - y₁)/(x₂ - x₁)
Entonces, para nuestra recta que pasa por los puntos (-4, 0) y (2, - 3) la pendiente será:
a = (-3 - 0)/(2 - (-4) )
a = -3/6 = -1/2
Entonces nuestra línea es algo como:
y = (-1/2)*x + b
para encontrar el valor de b, usamos el hecho de que esta línea pasa por el punto (2, -3)
esto significa que cuando x = 2, tenemos que tener y = -3
reemplazando esos dos valores obtenemos
-3 = (-1/2)*2 + b
-3 = -1 + b
-3 + 1 = b
-2 = b
La ecuación que define a esta recta es:
y = -(1/2)*x - 2
Nuevamente, el área de esta recta no está definida, por lo que no podemos calcular el área de esta recta.
A man is lying on the beach, flying a kite. He holds the end of the kite string at ground level and estimates the angle of elevation of the kite to be 65°. If the string is 350 ft long, how high is the kite above the ground? (Round your answer to the nearest foot.) ft
Answer: [tex]317.2\ ft[/tex]
Step-by-step explanation:
Given
Angle of elevation [tex]\theta=65^{\circ}[/tex]
Length of string [tex]L=350\ ft[/tex]
Suppose the height of kite from the ground level is h
from the figure, we can write
[tex]\Rightarrow \sin \theta=\dfrac{h}{L}\\\\\Rightarrow \sin 65^{\circ}=\dfrac{h}{350}\\\\\Rightarrow h=350\sin 65^{\circ}\\\Rightarrow h=317.2\ ft[/tex]
Solve the equation and enter the value of x below. 9x + 4 + x = 54
Hello!
9x + 4 + x = 54 <=>
<=> 9x + x + 4 = 54 <=>
<=> 10x + 4 = 54 <=>
<=> 10x = 54 - 4 <=>
<=> 10x = 50 <=>
<=> x = 50 : 10 <=>
<=> x = 5 => 9 × 5 + 4 + 5 = 54
Good luck! :)
Answer:
x = 5
Step-by-step explanation:
First, combine like terms. Like terms are terms with the same variables as well as same amount of said variables:
9x + x + 4 = 54
(9x + x) + 4 = 54
10x + 4 = 54
Next, isolate the variable, x. Note the equal sign, what you do to one side, you do tot he other. Do the opposite of PEMDAS.
PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
-
First, subtract 4 from both sides of the equation:
10x + 4 (-4) = 54 (-4)
10x = 54 - 4
10x = 50
Next, divide 10 from both sides of the equation:
(10x)/10 = (50)/10
x = 50/10 = 5
x = 5 is your answer.

What fraction of a circle does an arc measure of 30 degrees encompass?
1/12
1/4
1/6
1/3
Answer:
[tex]\frac{1}{12}[/tex]
Step-by-step explanation:
A full circle consists of 360°, so we can write the fraction of this arc as [tex]\frac{30}{360}[/tex], which can be simplified to [tex]\frac{1}{12}[/tex] by dividing the numerator and denominator by 30.

Step-by-step explanation:
You wish to purchase a new car and can afford monthly repayments of up to $250 per month. You see a car you like for $12,000 and are offered financing to secure the purchase. The loan lasts for 5 years and the annual interest rate is 17.9%. Can you afford to purchase the car on finance?
Answer:
Since the finance’s monthly required payment of $304.07 is greater than the $250 monthly that you can afford, this implies that you CANNOT afford to purchase the car on finance.
Step-by-step explanation:
The monthly required payment of the finance can be calculated using the formula for calculating the present value of an ordinary annuity as follows:
PV = M * ((1 - (1 / (1 + r))^n) / r) …………………………………. (1)
Where;
PV = Present value or finance amount = $12,000
M = Finance’s monthly required payment = ?
r = Monthly interest rate = Annual interest rate / 12 = 17.9% / 12 = 0.179 / 12 = 0.0149166666666667
n = number of months = Number of years * 12 = 5 * 12 = 60
Substitute the values into equation (1) and solve for M, we have:
$12,000 = M * ((1 - (1 / (1 + 0.0149166666666667))^60) / 0.0149166666666667)
$12,000 = M * 39.464764662266
M = $12,000 / 39.464764662266 = $304.07
Since the finance’s monthly required payment of $304.07 is greater than the $250 monthly that you can afford, this implies that you CANNOT afford to purchase the car on finance.
If (2,1) is the midpoint of the line segment ST and the coordinates of S are (5,4), find the coordinates of T.
Answer:
Step-by-step explanation:
The formula to find the midpoint of a segment is
[tex]M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex] and we have the midpoint and we also have a coordinate of (5, 4). Let's let x₁ = 5 and y₁ = 4. Filling in what we have:
[tex](2,1)=(\frac{5+x_1}{2},\frac{4+y_2}{2})[/tex] and we'll deal with the x terms first. The x coordinate of the midpoint is 2, so:
[tex]2=\frac{5+x_2}{2}[/tex] and multiply both sides by 2 to get rid of the denominator to get:
4 = 5 + x₂ so
x₂ = -1. Going on to the y coordinate. The y coordinate of the midpoint is 1, so:
[tex]1=\frac{4+y_2}{2}[/tex] and again multiply both sides by 2 to get rid of the denominator to get:
2 = 4 + y₂ so
y₂ = -2
The coordinates of T are (-1, -2)
Need help on this!! 10 points!!
Answer:
Step-by-step explanation:
The change of base formula is
[tex]log_a(b)=\frac{log_{10}b}{log_{10}a}[/tex] so filling in our given:
[tex]log_{13}}(297)=\frac{log_{10}297}{log_{10}13}[/tex] (Note: you do not have to put the base of 10 in the change of base formula because the "normal" base for a log is 10 and that is how your calculator figures it.)
Do this on your calculator to get
[tex]\frac{log297}{log13}=2.2198[/tex] Not sure how many decimal places you needed!

please somebody help me with this please help ASAP
Step-by-step explanation:
I don't know what your teacher wants to hear here.
can you use and construct certain angles (particularly 90 degrees), can you use compasses ?
for me the best way would be to draw one side as given. then use compasses and draw a half-circle from each end point of the line above the line. both circles have the radius = the given diameter.
then draw the next 2 sides of the square up from the end points of the first line towards the half-circle that was drawn from the other point, so that the end point is exactly on the circle bow. and then connect the engaging endpoints of these 2 sides.
similar for the rectangle.
the only difference is that now for the two sides (which we don't know the length) we need to go up exactly 90 degrees until the lines hit the half-circles.
-5(x+4) + -3x + -9x+-7
Answer:
x - 27
Step-by-step explanation:
Our goal here is to solve for x.
Start by performing the indicated multiplication:
-5(x+4) + -3x + -9x+-7 => -5x - 20 - 3x + 9x - 7
Combine like terms: x - 27
Answer:
[tex]-5(x+4) + -3x + -9x+-7[/tex]
[tex]\longmapsto -5\left(x+4\right)+\left(-3\right)x+\left(-9\right)x+\left(-7\right)[/tex]
[tex]\longmapsto -5\left(x+4\right)-3x-9x-7[/tex]
[tex]\longmapsto -5(x+4)=-5x-20[/tex]
[tex]\longmapsto -5x-20-3x-9x-7[/tex]
[tex]\longmapsto =-17x-27[/tex]
[tex]ANSWER:=-17x-27[/tex]
