Suppose that 12 inches of wire costs 48 cents.
At the same rate, how much (in cents) will 31 inches of wire cost?

Answer:

45

Step-by-step explanation:

5x 7 = 35

5 x 2 = 10

35 +10=45

The value of x in the equation  [tex]3^2^x = 9^3^x^-^4[/tex] is 2.

Two or more expressions with an Equal sign is called as Equation.

The given equation is [tex]3^2^x = 9^3^x^-^4[/tex]

We need to find the value of x.

We can write the given equation as below to make the bases same.

as 9 is equal to 3²

[tex]3^2^x = 3^2^(^3^x^-^4^)[/tex]

Apply distributive property in exponential part.

[tex]3^2^x = 3^(^6^x^-^8^)[/tex]

Now compare the exponential part as the bases are same

2x=6x-8

8=6x-2x

8=4x

Divide both sides by 4

x=2

Hence, the value of x in the equation  [tex]3^2^x = 9^3^x^-^4[/tex] is 2.

Answer:

[tex]\frac{1}{3}, \frac{2}{5} , \frac{3}{4} , \frac{4}{5}[/tex]

Step-by-step explanation:

Start by making a common denominator. That way we can just compare the numerators of the fractions and easily order then from least to greatest. Start by finding the LCM(least-common-multiple) of the denominators.

The LCM of 3, 4, and 5, is 60.

So let's make each of the fractions have a denominator of 60.

Start with [tex]\frac{2}{5}[/tex],

[tex]\frac{2}{5} =\frac{x}{60}[/tex], no we have to solve for x, and since we multiply by 12 to get to 60 from 5, we multiply 2 by 12 as well.

So, [tex]x=24[/tex].

Now do the same for each fraction.

[tex]\frac{1}{3} =\frac{x}{60}[/tex], we multiply by 20, so [tex]x=20[/tex]

[tex]\frac{4}{5} =\frac{x}{60}[/tex], we multiply by 12, so [tex]x=48[/tex]

[tex]\frac{3}{4}=\frac{x}{60}[/tex], we multiply by 15, so [tex]x=45[/tex]

So now are new fractions are [tex]\frac{24}{60} , \frac{20}{60} ,\frac{48}{60} , \frac{45}{60}[/tex]

Now just order these like normal since they have a common denominator.

[tex]\frac{20}{60} ,\frac{24}{60} , \frac{45}{60} , \frac{48}{60}[/tex]

Now revert them and make them there original values

[tex]\frac{1}{3}, \frac{2}{5} , \frac{3}{4} , \frac{4}{5}[/tex]

Using the z-distribution, as we are working with a proportion, considering that the estimate is of 90%, the 95% lower​ limit is of 0.8785.

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

In this problem, we have that:

Hence, the lower bound of the interval will be given by:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.9 - 1.96\sqrt{\frac{0.9(0.1)}{750}} = 0.8785[/tex]

The variable expression for "twenty-nine more than one-third of the square of z" is (1/3) × z² + 29.

Given information:

29 greater than one-third of the square of z

Let's break down the sentence into parts to create a variable expression as follows:

The square of z as show below:

z²

One-third of the square of z given as:

(1/3) × z²

Twenty-nine more than one-third of the square of z as given below:

(1/3) × z² + 29

So, the variable expression for "twenty-nine more than one-third of the square of z" is (1/3) × z² + 29.

Answer: Number from 1 through 50. 50 possible numbers. multiple of 10 : 10, 20, 30, 40, 50. 5 possible events. multiple of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48. 12 possible events one-digit number: 1, 2, 3, 4, 5, 6, 7, 8, 9. 9 possible events P(multiple of 10) = 5/50 or 1/10 P(not 100) = 50/50 or 1 P(not a multiple of 4) =  38/50 or 19/25  P(one-digit number) = 9/50  

Answer: See below

Step-by-step explanation:

Test 1:

5 numbers that are a multiple of 10

Total amount of numbers = 50

Probability = 10/50

P = 1/5 or 20%

Test 2:

None of the numbers from 1 to 50 are 100, so obviously the probability will be 1 or 100%

Test 3:

12 multiples of 4 in all 50 numbers, since we want numbers that are not multiples of 4 we subtract the total number of them from 50

50 - 12 = 38

Probability = 38/50

P = 19/25 or 76%

Test 4:

There are 9 one-digit numbers in total

Probability = 9/50

P = 9/50 or 18%

The least number of mice that he has to take out of his hat would be 23.

We have the following details to solve this problem

x = 14

t = 8

u = 6

n1 = x + t + 1

= 14 + 8 + 1 = 23

​

n2 = t + u + 1

= 8 + 6 + 1 = 15

​

n3 = x + u + 1

= =14+6+1=21

From here the

max n (n1, n2, n3) = 23, 15, 21

Hence the least number that has to be taken out would be 23.
