7x + 15 = 41 or 7x - 15 = 41
Answer:
7x - 15 = 41
Step-by-step explanation:
The key word is "difference" so keep that in mind. 7 times a number and 15 is 41. The "number" is unknown so a variable can be put in place until the number is known. The whole equation equals 41. The word "and" is where the "difference" or subtraction sign should go. Now we have a translated description! I hope this helps and if I'm wrong, please let me know!
Please can somebody help me please!
Answer:

Write an explicit formula for an, the nth term of the sequence 1, 11, 21
Answer:
an = 10n - 9.
Step-by-step explanation:
This is arithmetic with first term a1 = 1 and common difference 10.
an = a1 + d(n-1)
= 1 + 10(n - 1)
= 1 + 10n - 10
= 10n - 9.

Answer:
$3.48 for each pair of socks.
Step-by-step explanation:
It's a little confusing, because it says they're buying 2 socks, but then asks for the price of each of 2 *pairs* of socks. I'm going to believe the first sentence should say they paid for 2 pairs of socks.
They have $10, and get $3.04 in change. So we'll subtract $3.04 from $10 to find out the cost of 2 pairs of socks.
10 - 3.04 = 6.96
Then divide $6.96 by 2 pairs of socks
6.96/2 = $3.48 for each pair of socks.
The figure shows a plane slicing through a cone. The plane is neither parallel nor perpendicular to the base of the cone, and the plane does not intersect the base of the cone.
==================================================
Explanation:
Imagine that this plane was a saw blade, or a laser, that cut the cone. We would have two pieces and each piece would have a shape of an ellipse on them. The cutting plane would also have the same ellipse shape.
Or you think of the cutting plane as a flat piece of cloth. If we cut everything around the cone, then we would have an ellipse shaped hole as a result.
The reason why we get an ellipse and not a circle is because the plane is angled like that. It needs to be perfectly parallel to the circular base in order to get a circular cross section.

An automobile insurance company divides customers into three risk categories: Good (G), Medium (M), and Poor (P). Assume the following distribution of customers: 70% are Good risks, 20% are Medium risks, and 10% are Poor risks. Assume that the probabilities of a customer filing an accident claim (C) in the course of a year are: 0.5% for Good, 1% for Medium, and 2.5% for Poor. A customer is chosen at random.
a) What is the probability that the customer is a good risk and has filed a claim?b) What is the probability that the customer has filed a claim?c) Given that the customer has filed a claim, what is the probability that the customer is a good risk?
Answer:
a) 0.035 = 3.5% probability that a customer is a good risk and has filed a claim.
b) 0.0395 = 3.95% probability that the customer has filed a claim.
c) 0.8861 = 88.61% probability that the customer is a good risk
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
a) What is the probability that the customer is a good risk and has filed a claim?
70% are good risks.
Of those, 0.5% file a claim. So
[tex]0.7*0.05 = 0.035[/tex]
0.035 = 3.5% probability that a customer is a good risk and has filed a claim.
b) What is the probability that the customer has filed a claim?
0.5% of 70%(good risks)
1% of 20%(medium risks)
2.5% of 10%(poor risks). So
[tex]0.05*0.7 + 0.01*0.2 + 0.025*0.1 = 0.0395[/tex]
0.0395 = 3.95% probability that the customer has filed a claim.
c) Given that the customer has filed a claim, what is the probability that the customer is a good risk?
0.0395 = 3.95% probability that the customer has filed a claim means that [tex]P(A) = 0.0395[/tex]
0.035 = 3.5% probability that a customer is a good risk and has filed a claim means that [tex]P(A \cap B) = 0.035[/tex]
Thus
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.035}{0.0395} = 0.8861[/tex]
0.8861 = 88.61% probability that the customer is a good risk

The cost of 3 pounds of grapes is $9.75. What is the constant of proportionality that relates the cost in dollars, y, to the number of pounds of grapes, x? pls help, its due by the end of the day (3 pm)
Answer:
3.75
Step-by-step explanation:
We can write a ratio to solve
3 lbs x lbs
---------- = -----------
9.75 y dollars
Using cross products
3y = 9.75 x
Divide each side by 3
3y/3 = 9.75x/3
y =3.75x
The constant is 3.75

which of the following is equivalent to (5-7i)(5-7i)
Answer:
Step-by-step explanation:
Here we are multiplying together two complex numbers which happen to be identical: both are 5 - 7i).
This is also "the square of 5 - 7i: (5 - 7I)^2
In both cases, the result is 25 - 35i - 35i - 49, or 74 - 70i

chhering deposite rs. 40000 in a bank at the rate of 5% p.a. if he has to pay 5%of the total interest as tax for the bank how much will he get after 4 years
Answer: Rs 7600
Step-by-step explanation:
The interest will be calculated as:
= Principal × Rate × Time
= 40000 × 5% × 4
= 40000 × 0.05 × 4
= 8000
Since he has to pay 5% of the total interest as tax for the bank, the amount that he will he get after 4 years will be:
= 8000 - (5% × 8000)
= 8000 - (0.05 × 8000)
= 8000 - 400
= 7600
Therefore, he'll get Rs 7600

Answer:
2x + 4 = 6x
68 = 6x
6 6
11.33
11.3 = x
Angle 3 and angle 8 are corresponding. So we firstly find 2x + 4 which is 6x
Since we are looking for x we divide 68 from 6 which gives u 11.3
