2x – 14 = -9


x = 10

x = 2.5


x = -2.5

x = -10

Answers

Answer 1

Answer: x = 2.5

Step-by-step explanation: Add 14 to both sides. After that take the number left on the right side (5) and divide it by 2. That leaves you with x = 2.5

Answer 2
the answer to the question is 2.5

What is a fraction?

A fraction is a part of a whole number, and a way to split up a number into equal parts. It is a number expressed as a quotient, in which a numerator is divided by a denominator.

For the given situation,

The fraction is given as  [tex]\frac{4\frac{1}{2} }{1\frac{1}{4} }[/tex]

⇒ [tex]\frac{\frac{9}{2} }{\frac{5}{4} }[/tex]

⇒ [tex]\frac{9}{2}[/tex] × [tex]\frac{4}{5}[/tex]  

⇒ [tex]\frac{18}{5}[/tex]

⇒ [tex]3\frac{3}{5}[/tex]

Thus from the above value a = 3, b= 3, c= 5.

Hence we can conclude that the values of the fraction are a = 3, b= 3,   c= 5 is the correct answer.

An ant crept to a hole, which was 210 cm away.
It crept 40 cm per minute, but the wind pushed
it back 5 cm every minute. How many minutes
will it take the ant to reach the hole?

Answers

Answer:

6 minutes

Step-by-step explanation:

The ant can crawl 40 cm per minute but is pushed back 5 cm every minute aswell. In total the ant will crawl 35 cm per minute (40 - 5 = 35).

In order to find how long it will take for the ant to reach the hole we divide 210 by 35 (210/35) to get the answer of 6, therefore it takes the ant 6 minutes to reach the hole.

1.3.3- You currently have $50. You plan on spending $2 each day on candy at the
comer store on your way home from school. How long will it take until you are
left with only $18?
Your answer

Answers

Answer:

It will take 16 days.

Step-by-step explanation:

50-18=32

32/2=16

32 represents the total amount of money spent before ending up with $18 left. If you spend $2 a day, just divide 32/2 (Total/Rate?). The final answer is 16 days.

To check, divide 50/2 to get 25 (days) and subtract the days we have (16).

25-16=9

9x2=18 or the $18 in the end of the problem.

of bananas on Wednesday

Answers

Answer:

2

Step-by-step explanation:

f(x)= 0.90(0.59*2)

A grocery store sells bananas for $0.59 per pound. On Wednesdays, the store offers a 10% discount to senior citizens. We need to create a function f(x) which models the amount in dollars, a senior citizen would pay for 2 pounds

What is a simple Equation?

A mathematical equation which represents the relationship of two expressions on either side of the sign.

The 10% discount will make it so the senior citizens will pay 90% of the price.

90%=0.90

Also we need to know that 0.59*2 means how much money per pound the bananas cost.

So when you put it together, you should get f(x)=0.90(0.59*2)

The function f (x)=0.90(0.59*2) which models the amount, in dollars, a senior citizen would pay for 2 pounds of bananas on Wednesday

So the required function is f(x)=0.90(0.59*2)

a. A​ relative-frequency distribution is to a variable as a​ ___probability_______ distribution is to a random variable. b. A​ relative-frequency histogram is to a variable as a​ _____probability_____ histogram is to a random variable.

Step-by-step explanation:

Probability is a type of mathematics which deals with numerical descriptions of how likely an event would occur, or how likely it is that a the occurrence would be true. The probability of an event is usually between 0 and 1,

where 0 represent impossibility and 1 represents the chance of it occurring.

a. A​ relative-frequency distribution is to a variable as a​ frequency distribution is to a random variable.

b. A​ relative-frequency histogram is to a variable as a​  frequency histogram is to a random variable.

The relative frequency of an event is defined as the number of times that the event occurs during experimental trials, divided  by the total number of trials conducted.

A frequency distribution is an overview of all distinct values in some variable and the number of times they occur.

If there are many data points and we would like to see the distribution of the data, we can represent the data by a frequency histogram or a relative frequency histogram.

So, a. A​ relative-frequency distribution is to a variable as a​ frequency distribution is to a random variable.

b. A​ relative-frequency histogram is to a variable as a​  frequency histogram is to a random variable.

Zenzizenzicube is an obsolete word that represents the square of the square of a cube. In​ symbols, zenzizenzicube is written as

(((x^3)^2))^2

Required:
a. Use the chain rule twice to find the derivative.
b. Use the properties of exponents to first simplify the​ expression, and then find the derivative.

Answers

Answer:

Step-by-step explanation:

Given the expression (((x^3)^2))^2

a) Differentiating the function with respect to x using chain rule.

Given y = (((x^3)^2))^2

Let u = (x³)²

y = u²; dy/du = 2u

Let p = x³; dp/dx = 3x²

u = p²; du/dp = 2p

Applying the chain rule formula:

dy/dx = dy/du • du/dp • dp/dx

substitute in the formula

dy/dx = 2u•2p•3x²

Since u = (x³)² and p = x³

dy/dx = 2(x³)²(2x³)(3x²)

dy/dx = 12x^6•x^5

dy/dx = 12x¹¹

b) Using property of exponent

y = (((x^3)^2))^2

y = (x^6)²

y = x¹²

dy/dx = 12x^12-1

dy/dx = 12x^11

Find the value of f(15) if f(x) = 100x – 5x2.

Answers

this problem is to replace the variable (here "x" ) with a certain numerical value.

the given function is f(x) followed by the algebraic expression " 100x -5x^2 "

now u r asked to find f(15), mean u have to find the value of the "expression" with the numerical value "15" replacing "x"

so it looks like this:

f(x) = 100x -5x^2

f(15) = 100*15 - 5*(15)^2   [only "x" got replaced by it's numerical value "15"]

now u can calculate it

so

f(15) = 1500 - 5*225 = 1500 - 1125 = 375 (Ans.)

hope u got the basic idea.

feel free to ask if u have further queries.

y = -5/3x -7

Step-by-step explanation:

If lines are parallel they have the same slope m = -5/3. Just need to figure out the new y-intercept going through the point (-9, 8).

y = mx + b

8 = -5/3(-9) + b

8 = 15 + b

b = -7

Now use m and b to form new equation of parallel line.

y = mx + b

y = -5/3x -7

"An economist wants to estimate the mean per capita income (in thousands of dollars) for a major city in Texas. Suppose that the mean income is found to be $20.3 for a random sample of 2333 people. Assume the population standard deviation is known to be $11.3. Construct the 98% confidence interval for the mean per capita income in thousands of dollars. Round your answers to one decimal place."

Answers

Answer: ($19.8, $20.8)

Step-by-step explanation:

Confidence interval for mean : [tex]\overline{x}\pm z^*\dfrac{\sigma}{\sqrt{n}}[/tex] , where [tex]\overline{x}[/tex] = Sample mean, n= sample size, [tex]\sigma[/tex] = population standard deviation, z* = two tailed critical z-value.

Given:  [tex]\overline{x}[/tex] = $20.3

n= 2333

[tex]\sigma[/tex] = $11.3

For  98% confidence,  z* = 2.326

Then, the98% confidence interval for population mean will be:

[tex]20.3\pm (2.326)\dfrac{11.3}{\sqrt{2333}}\\\\=20.3\pm (2.326)\dfrac{11.3}{48.3011387}\\\\=20.3\pm (0.544165224825)\\\\\approx 20.3\pm 0.5\\\\=(20.3-0.5,\ 20.3+0.5)\\\\=(19.8,20.8)[/tex]

Hence,  the 98% confidence interval for the mean per capita income in thousands of dollars = (19.8, 20.8)
