Answer:
a) 2/5
b) 1/10
Step-by-step explanation:
There are 20 people total.
a is that the chosen child is a girl.
2 + 6 = 8, --> there are 8 girls --> simplify
8/20 = 4/10 = 2/5
b is the probability that the chosen child is a left-handed girl, --> there are 2 left-handed girls --> 2/20 --> simplify to 1/10
And thus, we have our answers.
Answer:
A) 2/5
B) 1/10
Step-by-step explanation:
A) Total Girls = 8
Total Children = 19
Probability = [tex]\frac{NumberOfFavourableOutcomes}{Total No.OfOutcomes}[/tex]
Probability = 8/20 = 4/10 = 2/5
B) Left-handed girls = 2
Total left handed children = 20
=> Probability = [tex]\frac{NumberOfFavourableOutcomes}{Total No.OfOutcomes}[/tex]
=> Probability = 1/10
On december 31, there were 40 units remaining in ending inventory. these 40 units consisted of 5 from january, 6 from february, 10 from may, 4 from september, and 15 from november. using the specific identification method, what is the cost of the ending inventory?
Answer:
$5,675
Step-by-step explanation:
Answer:
Step-by-step explanation:
Calculation for the cost of the ending inventory using specific identification method.
Using this formula
Cost of ending inventory =
(January units ×January cost) +( February units ×February cost) + (May units × May cost) + (September units ×September cost) + (November units × November cost)
Cost of ending inventory =
January 5 units ×$116=$580

Four times a number added to 3 times a larger number is 31. Seven subtracted from the larger number is equal to twice the smaller number. Let x represent the smaller number and y represent the larger number. Which equations represent this situation? y = negative four-thirds x + 31. y = 2 x + 7. y = negative four-thirds x + StartFraction 31 Over 3 EndFraction. Y = 2 x + 7. y = negative four-thirds x + 31. y = negative 2 x + 7. y = negative four-thirds x + StartFraction 31 Over 3 EndFraction. Y = negative 2 x + 7.
Answer:
Let x represent the smaller number and y represent the larger number
For the first equation
Four times a number added to 3 times a larger number is 31 is written as
4x + 3y = 31
Making y the subject we have
3y = - 4x + 31
Divide both sides by 3
That's
[tex]y = - \frac{4}{3} x + \frac{31}{3} [/tex]
For the second equation
Seven subtracted from the larger number is equal to twice the smaller number is written as
y - 7 = 2x
Making y the subject
We have
y = 2x + 7Hope this helps you
Answer:
first one (A)
Step-by-step explanation:
What is the range of the function f(x) = 2x + 1 given the Domain D = {-1,0, 1, 2}?
R = {0, 1,3,5)
R= {-1,1,3,5)
R = {-5, -3,-1,1)
R = {0, 1,3,6}
Answer:
R= {-1,1,3,5)
Step-by-step explanation:
To find the range, use the domain values as the input and find the output for the function
Domain D = {-1,0, 1, 2}?
f(x) = 2x + 1
f(-1) = -2 +1 = -1
f(0) = 0 + 1=1
f(1) = 2 + 1 = 3
f(2) = 4 + 1 = 5
The range is { -1,1,3,5}
WILL CHOOSE BRAINLIEST 5 STARS AND THANKS...How many 6-digit numbers, formed using each digit from 1 to 6 exactly once, are divisible by: Divisible by 5 Divisible by 12 Divisible 25
Answer:
( edited )
1. divisible by 5 : 120
2. divisible by 12 : 192
3. divisible by 25 : 24
See explanations below.
Step-by-step explanation:
Given:
6 digit number
digits all unique between 1 to 6
divisible by 5, 12 and 25
Find how many such numbers
solution:
1. Divisible by 5.
The last digit must be 5. That leaves five digits (1,2,3,4,6) for the rest of the numbers. So there are 5! = 120 such numbers.
2. Divisible by 12 (edited again)
All numbers formed from unique digits 1,2,3,4,5,6 are divisible by 3, since 1+2+3+4+5+6 = 21 which is divisible by 3.
For the 6 digit numbers divisible by 12, the two end digits must be divisible by 4, for which there are 8 ( 12,16,24,32,36, 52, 56, 64)
For each of the 8 numbers, we have 4 more digits to tag on for which there are 4! = 24 permutations. Thus there are 8*24 = 192 numbers divisible by 12.
3. divisible by 25
All numbers ending in 00, 25, 50 or 75 are divisible by 25.
Using digits 1 to 6, only those ending in 25 qualify.
Thus that leaves us with 4 digits to make 4! = 24 variations.
Thus there are 24 such numbers.

Answer:
[tex]y=28[/tex]
Step-by-Step Explanation:
Please refer to the attachment below.
So, notice that to find y, we simply need to determine x.
Remember that the area of a parallelogram is given by bh.
We can see that our base is x.
And our height h is half of 14. Therefore, h=7.
So, the area of one parallelogram is:
[tex]A=7x[/tex]
Then the area of four parallelograms is:
[tex]A=4(7x)=28x[/tex]
Since the total area of the shape is 308 squared centimeters. This means that:
[tex]308=28x[/tex]
Therefore:
[tex]x=11[/tex]
Then it follows that:
[tex]\begin{aligned} y&=2x+6\\ &=2(11)+6 \\ &=22+6 \\ &=28\end{aligned}[/tex]
how to calculate 71-5(3)-(4*4)
Answer:
40
Step-by-step explanation:
first do what is in the parentheses (4*4) which is 16 then rewrite the whole equation. 71-5(3)-16. then you'll want to multiply 5 times 3 because if there is no sign before the parentheses then it is automatically multiplication. 5 times 3 is 15. rewrite the equation again. 71-15-16 then simply subtract.
Hope this helps! :)
Si incrementa 35% los precio de un restaurante.Si un salmón a la mostaza lo vendía en 28,50 y un pollo al curry en 32,80¿cuales serán los nuevos precios de estos platos?¿cual sera el monto neto que recibirá por plato sin incluir el 18%de igv?
Answer:
Los nuevos precios serán 38.50 por el salmón y 44.30 por el pollo.
El monto neto recibido será 31.57 por el salmón y 36.32 por el pollo.
Step-by-step explanation:
Para resolver este problema primero debemos calcular el 35% del precio de ambos platos para saber cuánto se incrementará su precio.
Salmón a la mostaza:
Precio anterior: 28.50
El 35% de 28.50 es (28.50)(.35) =9.975
Precio nuevo = 28.50 + 9.975 = 38.475 = 38.50
Pollo al curry
Precio anterior: 32.80
El 35% de 32.80 es (32.80)(.35) = 11.48
Precio nuevo = 32.80 + 11.48 = 44.28 = 44.30
Ahora, para calcular el monto neto que recibirá por plato sin incluir el 18% de IGV tenemos que calcular el 82% del precio de cada plato (pues 100 - 18 = 82) y este será el monto neto que se recibirá.
Salmón a la mostaza.
Precio nuevo: 38.50
El 82% de 38.50 es (38.50) (.82) = 31.57
Se recibirá 31.57 por el Salmón a la mostaza.
Pollo al curry
Precio nuevo: 44.30
El 82% de 44.30 es (44.30) (.82) =36.32
Se recibirá 36.32 por el Pollo al curry.
An insurance company models the number of warranty claims in a week on a particular product that has a Poisson distribution with mean 4. Each warranty claim results in a payment of 1 by the insurer. Calculate the expected total payment by the insurer on the warranty claims in a week.
Answer:
4 monetary units
Step-by-step explanation:
In a Poisson distribution, the expected value of the distribution is the same as the mean:
[tex]E(X)=\mu=4\ claims[/tex]
The expected number of warranty claims is 4.
Since each claim results in a payment of 1, the expected value paid by the insurer is:
[tex]E(V)=E(X)*V(X)\\E(V)=4*1 = 4[/tex]
The expected total payment on warranty claims is 4 monetary units.

Gravel is being dumped from a conveyor belt at a rate of 20 ft3 /min and its coarseness is such that it forms a pile in the shape of a cone whose base diameter and height are always equal. How fast is the height of the pile increasing when the pile is 15 ft high
Answer:
The height of the pile is increasing at the rate of [tex]\mathbf{ \dfrac{20}{56.25 \pi} \ \ \ \ \ ft/min}[/tex]
Step-by-step explanation:
Given that :
Gravel is being dumped from a conveyor belt at a rate of 20 ft³ /min
i.e [tex]\dfrac{dV}{dt}= 20 \ ft^3/min[/tex]
we know that radius r is always twice the diameter d
i.e d = 2r
Given that :
the shape of a cone whose base diameter and height are always equal.
then d = h = 2r
h = 2r
r = h/2
The volume of a cone can be given by the formula:
[tex]V = \dfrac{\pi r^2 h}{3}[/tex]
[tex]V = \dfrac{\pi (h/2)^2 h}{3}[/tex]
[tex]V = \dfrac{1}{12} \pi h^3[/tex]
[tex]V = \dfrac{ \pi h^3}{12}[/tex]
Taking the differentiation of volume V with respect to time t; we have:
[tex]\dfrac{dV}{dt }= (\dfrac{d}{dh}(\dfrac{\pi h^3}{12})) \times \dfrac{dh}{dt}[/tex]
[tex]\dfrac{dV}{dt }= (\dfrac{\pi h^2}{4} ) \times \dfrac{dh}{dt}[/tex]
we know that:
[tex]\dfrac{dV}{dt}= 20 \ ft^3/min[/tex]
So;we have:
[tex]20= (\dfrac{\pi (15)^2}{4} ) \times \dfrac{dh}{dt}[/tex]
[tex]20= 56.25 \pi \times \dfrac{dh}{dt}[/tex]
[tex]\mathbf{\dfrac{dh}{dt}= \dfrac{20}{56.25 \pi} \ \ \ \ \ ft/min}[/tex]
The height of the pile is increasing at the rate of [tex]\mathbf{ \dfrac{20}{56.25 \pi} \ \ \ \ \ ft/min}[/tex]
She puts a value in the box and says that the equation represents a direct variation. Which explains whether the equation could represent a direct variation
Answer:
y = kx where k>0
Step-by-step explanation:
A direct variation is in the form
y = kx
where k is a numerical positive constant ( i.e. > 0 )
Answer:
0
Step-by-step explanation:
If she puts 0 in the box she would have a direct variation.
Step-by-step explanation:
Given : She writes the equation y = 5x - __ with a missing value.
She puts a value in the box and says that the equation represents a direct variation.
We have to choose the correct option from the given options that explain that the equation could represent a direct variation.
When two variables are such that one is a constant multiple of other, we said they are in Direct variation.
That is in form of y = ax , here y and x are in direct variation.
Consider the given equation y = 5x - __
For the equation to be in direct variation the value of missing term has to be 0.
then equation becomes,
y = 5x
Thus, If she puts 0 in the box she would have a direct variation.

A garden consists of an apple tree, a pear tree, some cauliflower heads, and some cabbage heads. There are 40 vegetables in the garden. 24 of them are cauliflower heads. What is the ratio of the number of cauliflower heads in the garden to the number of cabbage heads?
24 cauliflower: 16 cabbage
Apples and pears are not vegetables, which means 40 - 24 = 16.
Answer:
24:16
Step-by-step explanation:
I think.
40 total - 24 cauliflower heads= 16 other vegtable.
Number of cauliflower heads: number of cabbage heads
24: number of cabbage heads (16)
Work out the surface area of this triangular prism
Answer:
1008 [tex]cm^2[/tex]
Step-by-step explanation:
Given:
Triangular prism with
Base of triangle = 5 + 9 = 14 cm
Height of triangle = 12 cm
Here, we have 3 faces of the prism as a rectangle, all have width = 20 cm
Lengths of faces = 13cm ,14cm and 15 cm respectively
To find:
Total surface area = ?
Solution:
3 faces are rectangular shape and 2 faces are triangular shape.
[tex]Area\ of\ rectangle = Length \times Width[/tex]
The formula for Total Surface Area of a triangular prism is given as:
[tex]TSA = 2 \times \text{Area of triangular base}+{\text{Area of rectangular faces}}\\\Rightarrow TSA = 2 \times \dfrac{1}{2}\times Base \times Height+{\text{Area of rectangular faces}}\\\Rightarrow TSA = 14 \times 12 + 15 \times 20+ 13 \times 20+ 14 \times 20\\\Rightarrow TSA = 168 + 840\\\Rightarrow TSA = 1008\ cm^2[/tex]
So, the total surface area of the given triangular prism is 1008 [tex]cm^2[/tex].

For a trapezoid, the midsegment is one-half of...
a) the opposing leg
b) the square of the largest leg
c) the same as the smallest leg.
d)the sum of the bases
Answer:
D
Step-by-step explanation:
Mathematically, the mid segment of a trapezoid is exactly the average of the 2 parallel bases
What this means is that to find the length of the trapezoid, we will need to find the average of the two parallel bases
Mathematically, this is same as adding the two bases and dividing the result by 2.
Hence we can say it is exactly one-half the length of the sum of the two parallel bases

Find the measure of angle C of a triangle ABC, if m∠A = α, m∠B = 2α
Answer:
The measure of angle C is 180 - 3α
Step-by-step explanation:
Given;
triangle ABC, ΔABC
angle A, ∠A = α
angle B, ∠B = 2α
To calculate angle C, we must recall that, the sum of angles in a triangle is equal to 180°. Angle A, angle B, and angle C make up the total angle in the triangle.
∠A + ∠B + ∠C = 180
where
∠C is angle C
α + 2α + ∠C = 180
3α + ∠C = 180
∠C = 180 - 3α
∠C = 3(60 - α)
Therefore, the measure of angle C is 180 - 3α
