A bag has 8 red marbles, 4 green marbles, and 2 yellow marbles. Bill draws a red marble from the bag and does not replace it. What is the probability of Bill drawing a yellow marble next? A. 1/7 B. 1/13 C. 2/13 D. 1/14
Answer:
c. 2/13
Step-by-step explanation:
The bag starts with 8 red marbles, 4 green marbles, and 2 yellow marbles. Since he draws a red marble from the bag and does not replace it, there will be one less marble.
So now there are 7 red marbles, 4 green marbles, and 2 yellow marbles. Add the number of marbles together and then find the probability of drawing a yellow marble.
7+4+2 = 13
2/13
So the probability of Bill drawing a yellow marble would be 2/13.

Two customers took out car loans from a bank. Jenna took out a 4-year loan for $20,000 and paid 4.8% annual simple interest. Francis took out a 5-year loan for $20,000 and paid 4.4% annual simple interest. What is the difference between the amounts of interest Francis and Jenna paid for their car loans? Enter your answer in the box. $
Answer:
The answer is 80 dollars difference
Step-by-step explanation:
The difference between the amount of interest Francis and Jenna paid for their car loans is $560.
What is the difference in the simple interest?Simple interest is when only the principal portion of the loan earns an interest and not both the interest already accrued and the principal portion of the loan.
Simple interest = principal x time x interest rate
Jenna = 4 x 20,000 x 0.048 = $3840
Francis = 5 x 20,000 x 0.044 = $4400
Difference = 4400 - 3840 = $560

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Whats the surface area? giving brainlest
Answer:
446 cm²
Step-by-step explanation:
area of cuboid (1) =
2lw + 2wh + 2hl
for cuboid (1)
length = 10cm
width = 7cm
height = 5cm
thus,
SA = 2(10)(7) + 2(7)(5) + 2(5)(10)
= 140 + 70 + 100
= 310 cm²
SA of cuboid (2) =
2lw + 2wh + 2hl
length = 4cm
width = 3cm
height = 8cm
SA of cuboid (2) = 2(4)(3) + 2(3)(8) + 2(8)(4)
= 24 + 48 + 64
= 136 cm²
total surface area of the composite figure =
SA (cuboid 1) + SA (cuboid 2)
=310 + 136
= 446 cm²
The purple rectangular prism has a length of 4 cm, a width of 3 cm, and a height of 8 cm.
The yellow rectangular prism has a length of 10 cm, a width of 7 cm, and a height of 5 cm
Step 1:Calculate the SA of the purple rectangular prism
\(A=2(wl+hl+hw)=2·(3·4+8·4+8·3)=136\)
The SA of the purple rectangular prism is 136 cm²
Step 2:Calculate the SA of the yellow rectangular prism
\(A=2(wl+hl+hw)=2·(7·10+5·10+5·7)=310\)
The SA of the yellow rectangular prism is 310 cm²
Step 3:Combine the results you got from the past 2 steps
310+136= 446 cm²
Answer:The total surface area of these two rectangular prisms is 446 cm²

Responses
A 3939
B 1616
C 3737
D 1313
E 17
Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

An architect plans to build an extension to Meiling's rectangular deck. Let x represent the increase, in meters, of her deck's length. The expression 2(x + 7) represents the area of the deck, where 2 is the width, in meters, and (x + 7) represents the extended length, in meters. Use the Distributive Property to write an expression that represents the total area of Meiling's new deck.
The expression should be 2x + 14
Calculation:Since 2 is the width, in meters, and (x+7) represents the extended length, in meters.So, area is:
\(A = 2(x+7)\)

\(A=(2\times x) + (2 \times 7)\)

Answer:
Step-by-step explanation:
So the algebraic expression here is:
let x-be the number of received eggs
1/3x + 320=(1-1/4)x
1/3x + 320 = 3/4x
Transposing 1/3x to the other side:
320=3/4x-1/3x
320=9/12x-4/12x
320=5/12x
Multiply both sides by 12:
3840=5x
Divided them both by 5:
x=768

Answer:
D (Alicia did 5 more jumping jacks per minute than Melissa.)
Step-by-step explanation:
Alicia's rate is 30 jumping jacks per minute. You can use the formula m=(y2-y1)/(x2-x1) to find the slope/rate. The two points in the table you can use are (1,30) and (2,60). You can plug those coordinates into the slope formula. (60-30)/(2-1)=30/1= 30 jumping jacks per minute. To find the rate of change/slope for Melissa, you can use the same formula m=(y2-y1)/(x2-x1). The two points you could plug in are (0,0), and (4,100). (100-0)/(4-0)=100/4=25. Melissa does 25 jumping jacks per minute.
