Answer 1

Answer:  No solution

Step-by-step explanation:

You can use desmos to plot the equations, if both lines are on top of each other it's infinite and if it crosses once it's one solution and if it's parallel or doesn't cross there is no solutions.

In this case the lines are parallel therefore there is no solution because they never cross to each other.

How many days will it take for a sum of $4,000 to earn $80 interest if it is deposited in a bank paying ordinary simple interest at the rate of 5%/year?

Answers

Answer:

It will take 146 days to earn an interest of $80.

Step-by-step explanation:

The simple interest formula is:

[tex]I=\frac{P\times r\times t}{100}[/tex]

It is provided that:

I = $80

P = $4,000

r = 5% p.a.

Compute the time required as follows:

[tex]I=\frac{P\times r\times t}{100}[/tex]

[tex]t=\frac{I\times 100}{P\times r}[/tex]

  [tex]=\frac{80\times 100}{4000\times 5}\\\\=0.4\ \years\\\\=0.4\times 365\ days\\\\=146\ days[/tex]

Thus, it will take 146 days to earn an interest of $80.

A theater sells adult tickets and student tickets. A total of 165 tickets are sold and the ratio of adult tickets sold to student tickets sold is 8 to 7. How many of each type of ticket are sold?

Answers

Answer:

88 adult tickets and 77 student tickets were sold.

Step-by-step explanation:

Let the number of adult tickets sold be 8x and the number of student tickets sold be 7x.

adult tickets + student tickets = 165 tickets

8x + 7x = 165

15x = 165

x = 165 ÷ 15

  = 11

No. of adult tickets sold (8x) = 11 × 8

                                               = 88

No. of student tickets sold (7x) = 11 × 7

                                                   = 77

88 adult tickets were sold and 77 student tickets were sold.

What is Equation?

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

Given,

A theater sells adult tickets and student tickets.

Let us consider number of adult tickets sold be 8x and the number of student tickets sold be 7x.

8x + 7x = 165

15x = 165

Divide both sides by 15

x = 165/15

= 11

No. of adult tickets sold (8x) = 11 × 8= 88

No. of student tickets sold (7x) = 11 × 7= 77

Hence, 88 adult tickets were sold and 77 student tickets were sold.

Step-by-step explanation:

A clothing company is considering a new insulation for winter coats. To collect customer satisfaction data on the new insulation, the company is considering two methods.

Method 1: The company offers the first 50 employees who volunteer to try out a coat with new insulation if they will report their satisfaction level after one month. At the end of the month, the 50 volunteers describe their satisfaction with the coat's performance.

Method 2: The company takes 50 volunteers and randomly assigns 25 of them to coats with the new insulation and the other 25 to coats with the current insulation. All volunteers wear the coats for a month and then describe their satisfaction with the coats’ performance.

Which method describes an experiment?

A.) Method 2 is an experiment because both groups report their satisfaction with the coats.

B.) Method 1 is an experiment because all volunteers receive coats with the new insulation.

C.) Method 2 is an experiment because volunteers are assigned one of the two insulation types.

Question 4 (5 points)
Evaluate the expression log 5 1/25.

A)-1/2
B)-2
3)1/2
4)2


Answers

Answer: B (-2)

Step-by-step explanation:

[log base b of a = c] turns into [b^c = a]

You have log base 5 of 1/25 = ?, so it turns into 5^? = 1/25

This part is sort of guess and check, but we can look at it to find the answer pretty easily. First, it's 1/n, so we should use a negative power: 5^-1 = 1/5

In addition to being in the denominator, it's 25, which is 5^2.

So, if we want to put it in a reciprocal as well as square it, we can use -2:

5^(-2) = 1/(5^2) = 1/25

Since -2 (B) is the exponent we place on 5 to get 1/25, it is also the answer to log base 5 of 1/25.

The value of log5 (1/25) is -2.

To evaluate the expression log5 (1/25), we need to determine the exponent to which we must raise 5 to get 1/25.

In other words, we need to find the value of x in the equation 5ˣ = 1/25.

We can rewrite 1/25 as 5⁻², since 5⁻² is equal to 1 divided by 5².

Now, we have the equation 5ˣ = 5⁻².

To find the value of x, we can equate the exponents:

x = -2.

Therefore, the value of log5 (1/25) is -2.

Option B) -2 is the correct answer.

The logarithm base 5 of 1/25 is -2 because -2 is the exponent to which we must raise 5 to obtain 1/25. In general, the logarithm function provides the exponent needed to produce a specific value as the result of raising the base to that exponent.

algebraic expressions are combinations of variables , numbers, and at least one arithmetic operation. For example, 2x+4y−9 is an algebraic expression. Term: Each expression is made up of terms.

The parts of algebraic expression are monimal, polynimial, binomial, trinomial, and multinomial. An algebraic expression represents all the possible values of variable it consist.

Algebraic Expression- Algebraic expression is the combination of variables, coefficient, constant or all three in a mathematical form  where both side set equal to each other.

Parts of algebraic expression-

The way algebraic expression can express are categorizes in 5 different parts. These are,

Monomial - In this type of algebraic expression in which at least one non zero terms exist.

        For example  [tex]ax^2[/tex]

       

Polynomial- In this type of algebraic expression in which one or more than one terms exist.

Multinomial In this type of algebraic expression in which three non zero terms exist.

        For example [tex]a^2+b+c^3+d[/tex]

An algebraic expression represents all the possible values of variable it consist. We use algebraic equation when we do not know the value of variable or unknown things. To find out the values of these variables the algebraic expression are useful.

Answers

Answer:

Standard deviation of given data = 3.16227

Step-by-step explanation:

Step(i):-

Given sample size 'n' = 5

Given data  4, 6,8,10,12

[tex]Mean = \frac{4+6+8+10+12}{5} = 8[/tex]

Mean of the sample x⁻ = 8

Standard deviation of the sample

                  [tex]S.D = \sqrt{\frac{Sum(x-x^{-} )^{2} }{n-1}}[/tex]

Step(ii):-

Given data

x          :         4      6       8       10      12

x-x⁻      :      4 - 8   6-8   8-8    10-8    12-8

(x-x⁻)   :        -4      -2     0          2        4

(x-x⁻)²  :        16     4       0         4        16  

 

  [tex]S.D = \sqrt{\frac{Sum(x-x^{-} )^{2} }{n-1}}[/tex]

  [tex]S.D = \sqrt{\frac{16+4+0+4+16}{4}}[/tex]

What is the base of the exponent in the function fx=3(3/8)^2

Answers

Answer:

by definition, an exponential function with base c is defined by h (x) = ac^x  

where a ≠0, c > 0 , b ≠1, and x is any real number.

The base, c, is a constant and the exponent, x, is a variable.  

so if we have  f(x)=3(3\8)^2x, this equivalent to f(x)=3(3\8)^y(x),  

where y (x)=2x,  

therefore, the base is  3/8, and the variable is the function y (x)=2x,  it is 4
