Answer: Distance of earth from star = [tex]24.78\times10^{14}\text{ miles}[/tex]

Step-by-step explanation:

Given: A certain star is [tex]4.2 \times 10^2[/tex] light years from the Earth.

One light year is about [tex]5.9 \times 10^{12}[/tex] miles.

Distance of earth from star = [tex]4.2\times10^2\times 5.9\times10^{12}[/tex]

[tex]=4.2\times5.9\times10^2\times10^{12}\text{ miles}\\\\=24.78\times10^{2+12}\text{ miles}\\\\=24.78\times10^{14}\text{ miles}[/tex]

Hence, Distance of earth from star = [tex]24.78\times10^{14}\text{ miles}[/tex]

Answer:

X + Y could equal to [tex]1 \frac{2}{5}X[/tex] or [tex]3 \frac{1}{2}Y[/tex].

Step-by-step explanation:

2X = 5Y

Y = [tex]\frac{2}{5}X[/tex]

X = [tex]\frac{5}{2}Y[/tex]

Hence, X + Y could equal to X + [tex]\frac{2}{5}X[/tex] = [tex]1 \frac{2}{5}X[/tex] or Y + [tex]\frac{5}{2}Y[/tex] = [tex]3 \frac{1}{2}Y[/tex].

Hence, X + Y could equal to [tex]1 \frac{2}{5}X[/tex] or [tex]3 \frac{1}{2}Y[/tex].

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.

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.

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]

 S.D = √10 = 3.16227

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.

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

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.
