Given the function g(x) = 2(5x + 5) - (3x + 2), determine the value of x for which g(x) = 43?
Vgjvhkhj
Answer:
x = 5
Step-by-step explanation:
g(x) = 2(5x + 5) - (3x + 2) = 43
2(5x + 5) - (3x + 2) = 43
10x + 10 - 3x -2 = 43
7x + 8 = 43
7x = 43 - 8
7x = 35
x = 35/7
x = 5

The amount of icing on a Cuppie Cake large cupcake follows a Normal distribution, with a mean of 2 ounces and a standard deviation of 0.3 ounce. A random sample of 16 cupcakes is selected every day and measured. What is the probability the mean weight will exceed 2.1 ounces?
Answer: the probability the mean weight will exceed 2.1 ounces is 0.09
Step-by-step explanation:
Let x be the random variable representing the amount of icing on a Cuppie Cake large cupcake. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/(σ/√n)
Where
x = sample mean
µ = population mean
σ = standard deviation
n = number of samples
From the information given,
µ = 2
σ = 0.3
n = 16
x = 2.1
the probability that the mean weight will exceed 2.1 ounces is expressed as
P(x ≥ 2.1)
For x = 2.1
z = (2.1 - 2)/(0.3/√16) = 1.33
We would determine the probability for the area above z = 1.33 from the normal distribution table. It would be
p = 1 - 0.91 = 0.09
P(x ≥ 2.1) = 0.09
Please help!! Will give Brainly to the best answer!!!!The function f(x) = -X² + 16x - 60 models the daily profit, in dollars, a shop makes for selling candles, where x is the number of candles sold.
Determine the vertex, and explain what it means in the context of the problem.
(6, 10): The vertex represents the maximum profit.
(6. 10): The vertex represents the minimum profit.
(8. 4): The vertex represents the minimum profit.
(8.4); The vertex represents the maximum profit.
Answer:
(8,4)
Step-by-step explanation:
The vertex means that the maximum amount of candles that you can sell is exactly 8 to obtain full profit.
The equation would be f(x) = -X² + 16x - 60
then -(x^2 -16x)-60 which then equals
-(x^2-16x+64-64)-60
then that would equal -(x-8)^2 +64 -60
which would give you the final answer of -(8x)^2 +4
Answer:
(8, 4); The vertex represents the maximum profit.

C. What is the total volume of the interior of the house?
Number model:
Answer: Cubic Feet
Answer:
43100 cubic feet
Step-by-step explanation:
Floor 1: 3700 * 8 = 29600
Floor 2: 50 * 30 * 9 = 13600
Total = 29600+13600=43100
The volume of the interior of the house is 29,600 cubic feet.
The volume of the second floor is 13,500 cubic feet.
The total volume of the interior of the house is 43,100 cubic feet.
What is the volume?The formula that can be used to determine the volume of a rectangular prism is : length x width x height
surface area x height
The volume of the interior of the house = 3700 x 8 = 29,600 cubic feet
The volume of the second floor - 50 x 30 x 9 = 13,500 cubic feet.
The total volume of the interior of the house = 29600 + 13500 = 43,100 cubic feet.

Answer:
A = 20972.44
Step by step explanation:
Principal (P) = 19000
Rate = 10% = 0.1
Time = 1 year
N (number of time the interest is compounded) = 4
Compound interest (A) = P(1 + r/n)^nt
A = 19000 * (1 + 0.1 / 4)^4*1
A = 19000 * (1 + 0.025)⁴
A = 19000 * 1.025⁴
A = 19000 * 1.1038
A = 20972.44
The interest at the end of the year is $20972.44

Step-by-step explanation:
We want Expected number of bases during 2009
E(bases) = SUM (number of outcomes) *probabiility of outcome
93 + 45 + 1 + 47 = 176 hits
but there are a total of 568 bats
568 - 176 = 392 misses?
E(Bases) = 0* P( miss) + 1 * P( hitting singles) + 2*P(hitting doubles) + 3*P(hitting triples) + 4*P(home run)
E(Bases) = 0 + 93/568 + 2* (45/568) + 3*(1/568) + 4*(47/568)
0.16373239 + 0.158450 + 0.0052816901 + 0.33098591549

A restaurant offers four sizes of pizza, two types of crust and eight toppings how many possible combinations of pizza with one topping are there
Answer:
64
Step-by-step explanation:
You know that:
there are four different sizes of pizza
two types of crust
and eight toppings
With a one-topping pizza, all you have to do is multiply 4 by 2 and then by 8
If it helps to branch it all out so you can visually see it, that would be a great idea
But in short, 4x2x8 is 64, so there are 64 combinations
:)
Final answer:
The number of possible pizza combinations with one topping is 64, calculated by multiplying the number of sizes, crust types, and toppings available, which are 4, 2, and 8 respectively.
Explanation:
To determine the number of possible combinations for a pizza with one topping, we apply the Fundamental Principles of Counting and use the Multiplication Principle.
Since there are four sizes of pizza, two types of crust, and eight toppings, we multiply these numbers together.
The calculation would be as follows:
Number of sizes = 4Number of crust types = 2Number of possible single toppings = 8Therefore, the number of possible pizza combinations with one topping is:
4 (sizes) x 2 (crust types) x 8 (toppings) = 64 combinations.

Step-by-step explanation:
Red: y = 7x
Blue: y = 5x
Green: y - 4x
Purple: y= 34
As x gets very large, which function becomes largest and remains so?
y = 7x
y = 5x
y = 4x2
y = 3
Final answer:
As the independent variable x grows very large, the quadratic function y = 4x^2 will outpace the linear functions y = 7x, y = 5x, and y = 34, hence it will become the largest and remain so.
Explanation:
The student is asking about the behavior of different linear functions and a quadratic function as the independent variable x becomes very large. When examining the functions given, we notice that three of them, y = 7x, y = 5x and y - 4x are linear, while the fourth, given the context should likely be a quadratic function y = 4x2, although that wasn't presented correctly in the question. As x grows, the function with the highest degree will become the largest. In this case, the quadratic function y = 4x2, which grows at a rate proportional to the square of x, will outpace the linear functions, whose growth is only directly proportional to x. Thus, as x becomes very large, the quadratic function “y = 4x2” becomes the largest and remains so.
Plz plz and explain please
Answer:
Yes, because 3/4 is bigger then 1/2 so there is more then 1 in there. The expression 1/2 divided by 3/4 is smaller then 1 because 3/4 is already bigger so you can't fit one in. Without using fractions it is like 3/2 is bigger then 1 since 2 is smaller then 3. 2 divided by 3 is less because 3 is bigger so you can't fit the 3 in a 2.

The expression 9 - 3 * 9 / 4 + 257 equals 259.25.
To solve the expression 9 - 3 * 9 / 4 + 257, we follow the order of operations (PEMDAS/BODMAS):
Calculate the multiplication and division from left to right: -3 * 9 / 4.
-3 * 9 = -27.
-27 / 4 = -6.75.
Now, the expression is:
9 - 6.75 + 257.
Perform the addition and subtraction from left to right:
9 - 6.75 = 2.25.
2.25 + 257 = 259.25.
Therefore, the value of 9 - 3 * 9 / 4 + 257 is 259.25.

A) blindness
B) paddle hands
C) no peripheral vision
D) fused hands, no range of motion
Answer:blindness I did it
Step-by-step explanation:
Blindness is likely the one mutation, that contributes to a rapid rate of extinction. Option A is correct.
Any change in a cell's DNA sequence. Mutations can be generated by errors during cell division or by exposure to DNA-damaging substances in the environment.
Here,
The most frequent kind, red-green color blindness, is caused by a genetic mutation on the X chromosome that is passed on to children. At fertilization, an egg has an X chromosome, and a sperm cell can have either an X or a Y chromosome.
Thus, Blindness is likely the one mutation, that contributes to a rapid rate of extinction. Option A is correct.

How does estimating an addition or subtraction problem help you know if ananswer is reasonable?
Answer:
To be reasonable means to be as much as is appropriate or fair.
In math, reasonableness can be defined as checking to verify that the result of the solution or the calculation of the problem is correct or not, be either estimating or by plugging in your result to check it.
When solving a math problem, we can check if the answer we have derived to is reasonable or not, based on an estimate. A reasonable estimate does not exceed the original numbers in a problem.
For instance, in a division problem like 424 ÷ 4 − 10, we can check is our answer is reasonable or not, by estimating an approximate answer or by plugin gin using the division formula.
We can round down 424 to the nearest hundreds, to estimate the answer. Since 96 (actual answer) ≈ 90 (estimate answer), we know our solution is correct.
We can check our solution by plugging in to verify using, 96 × 4 + 10 as well.
Step-by-step explanation:
When estimating an addition or subtraction problem, you can easily tell if it is reasonable or not. If you're having trouble with a problem, such as 1342+7864, and you're getting an answer of... 1300, but don't think its correct, you can estimate by rounding the numbers and adding them. For example, 1342=1300 and 7864=7900 (I'm using the rule that if the number is 4-0 I round down and if its 5-9 I round up.) Since we're woring with thousands you would try to get the most split, even value you can without taking off too much, so we would round the tens place. And after that you could add 1300+7900=9200. Then you would know your answer of 1300 is not reasonable and you have an error in your equation. Estimating is a great skill to have, and it really helps when you're just trying an equation out or get one of those "Estimate the sum of" questions.

Rewrite the function f(x)=7 (1/2)^3x using the properties of exponents.
The function [tex]\(f(x) = 7 \cdot 2^{-3x}\)[/tex] is a rewritten form using exponent properties.
To rewrite the function [tex]\( f(x) = 7 \left(\frac{1}{2}\right)^{3x} \) using the properties of exponents, we can first rewrite \( \frac{1}{2} \) as \( 2^{-1} \). Then, we can apply the property \( (a^m)^n = a^{mn} \)[/tex] to simplify the expression. Here's how it goes:
[tex]\[ f(x) = 7 \left(\frac{1}{2}\right)^{3x} \][/tex]
[tex]\[ = 7 \left(2^{-1}\right)^{3x} \][/tex]
[tex]\[ = 7 \cdot 2^{-3x} \][/tex]
So, [tex]\( f(x) = 7 \cdot 2^{-3x} \)[/tex] is the rewritten form of the function using the properties of exponents.
