Candy's Sweets Company charges $1.15 per pound to ship candy.
Part A: Write an equation to determine the total cost, c, to ship p pounds of candy. Use your equation to determine the cost of shipping 2 pounds of candy. (6 points)
Part B: If the company reduces the cost to ship candy by $0.25 per pound, write an equation to determine the total cost, c, to ship p pounds of candy with the reduced cost. (4 points)
Answer:
Part A: c = 1.15p
c = 1.15(2) c = 2.30
Part B: c = 0.9p
c = 0.9(4) c = 3.60
Answer:
Part A: c = 1.15p; The cost of shipping 2 pounds of candy is $2.30.
Part B: c = 0.9p
Step-by-step explanation:
Part A:
$1.15 --- 1 pound
$1 --- 1.15 pounds
Replace the money sign with c (since c represents the total cost) and replace pounds with p (since p represents pounds of candy)
c = 1.15p
We can then use this equation to find the c (cost) for 2p (2 pounds).
c = 1.15(2)
= 2.30
Thus, the cost of shipping 2 pounds of candy is $2.30.
Part B:
$1.15 - $0.25 --- 1 pound
$0.90 --- 1 pound
$1 --- 0.9 pound
Replace the money sign with c (since c represents the total cost) and replace pounds with p (since p represents pounds of candy)
c = 0.9p

Explain whether △ABC is congruent to △XYZ according to the angle side angle (ASA) congruence criteria.
Answer:
∆ABC and ∆XYZ cannot be proven to be congruent to each other according to the Angle-Side-Angle (ASA) Congruence criteria.
Step-by-step explanation:
The Angle-Side-Angle (ASA) Congruence criteria says that two triangles are congruent to each other if two angles and an included side of one triangle is congruent to two corresponding angles and a corresponding included side of the other triangle.
In the diagram given, the two angles were given (<B and <C), however, the side given (side AB) does not lie in the middle of <B and <C, hence it is NOT AN INCLUDED SIDE. The same applies to ∆XYZ.
Therefore, ∆ABC and ∆XYZ cannot be proven to be congruent to each other according to the Angle-Side-Angle (ASA) Congruence criteria.

The Council of American Beet Farmers estimate that 60% of Americans love beets.
Based on this estimation, determine the probability for each of the following scenarios. Round your answers to three decimal places.
In a survey of 22 Americans, exactly 15 of them will respond that they love beets.
Answer: 13% or 0.1314
Step-by-step explanation: Binomial PDF on the calculator or by hand its
22 nCr 15 (0.60)^15(1-0.6)^7 = 0.131378
The probability in a survey of 22 Americans where exactly 15 of them will respond that they love beets given that 60% of American love beets is 0.131.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
The binomial probability distribution:
[tex]^nC_r p^r (1 - p)^{n - r}[/tex]
Now,
p = 60% = 60/100 = 0.6
1 - p = 1 - 0.6 = 0.4
n = 22
r = 15
Now,
[tex]^nC_r p^r (1 - p)^{n - r}[/tex]
= [tex]^{22}C_{15}(0.6)^{15} (0.4)^{22 - 15}[/tex]
= [tex]^{22}C_{15}(0.6)^{15} (0.4)^7[/tex]
= 0.1313
Thus,
The probability is 0.131.

Deborah spent $70 on food and clothes she spent $26 more on clothes then on food Brighton solve a system of equations to find how much Debra spent on each
Answer:
Step-by-step explanation:
You know the total will be $70.
She bought food, let's call that "F"
She spent $26 more on clothes than food. So her clothes purchase is "F+26".
So let's set-up the equation this way:
food + clothing = Total Spent
F + F + 26 = 70
2F + 26 = 70 (subtract 26 from both sides of the = sign)
2F = 44 (Divide both sides so you find out how much was spent on "F" or food.)
F = 22 (But the question doesn't stop there.)
Deborah spent $22 on food. (Remember, she spent $26 more on clothes, so we have to use our "clothes" equation? ) Deborah spent $48 on clothes. She spent a total of $70 on her purchases.

1. A certain manufacturing process to build phone batteries results in the production of defective batteries at a rate of 5% (0.05). Suppose that 10 batteries are produced. a. Find the expected number of defective batteries. b. Find the variance and standard deviation in the number of defective batteries. c. Find the probability that at least 1 battery is defective.
Answer:
0.5 ; 0.475 ; 0.689 ; 0.4013
Step-by-step explanation:
Given that:
Rate of production of defective batteries p = 0.05
Number of batteries produced (n) = 10
The expected number of defective batteries = mean = n * p = 10 * 0.05 = 0.5 batteries
Variance of defective batteries :
Var(X) = n * p * q ; q = 1 - p
Hence,
Var(X) = 10 * 0.05 * 0.95 = 0.475
Standard deviation (X) = sqrt(variance) = sqrt(0.475) = 0.689
Probability that atleast 1 battery is defective :
Using the binomial probability function
P(x ≥ 1) = 1 - p(x = 0)
= 1 - q^n
= 1 - 0.95^10
= 1 - 0.59873693923837890625
= 0.40126306076162109375
= 0.4013

Which multiplication problem does the model represent?
A- 1/8 times 2
B- 7/8 times 2
C- 1/2 times 4
D- 1/4 times 8
The correct answer would be D- 1/4 times 8
This is the correct answer because if you look at the model, it shows 2 blocks of 1, and then 8 blocks of 1/4, which both equal 2, and the model does not say anything about the top row, only the bottom, and after process of elimination, you would be left with 1/4 times 8

The scale factor of a model plane to the actual plane is 1 to 25.
Find the wing area of the model if the wing area of the actual plane is 300 ft2
.
Step-by-step explanation:
Length on model : Length on actual = 1 : 25
=> Area on model : Area on actual
= 1² : 25² = 1 : 625.
Therefore area on model = 300ft² * (1/625) = 0.48ft².

Santiago starts a savings account with $20. Each month he deposits $15 more into the account. Santiago wants to save a least $80. Write an inequality that represents this situation.
Answer:
$20 + $15m ≥ $80
Step-by-step explanation:
He starts off with $20.
He adds $15 each month, so $15m.
He wants to save at least $80, which means greater than or equal to $80. So, you use this symbol: ≥
Put it all together.
$20 + $15m ≥ $80
