Answer:

y=  1/4(2+3x)

Step-by-step explanation:

The solution of the expression for the value of y is y = 8 + 12x.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The given expression is 3x-1/4y=-2. The value of y will be calculated as below:-

3x-1/4y=-2

-(1/4)y = -2 - 3x

y = 4 ( 2 + 3x)

y = 8 + 12x

Therefore, the solution of the expression for the value of y is y = 8 + 12x.

The description of the transformation of z on the complex plane gives the quotient is B. scale z by a factor of 1 and rotate it 5 degrees clockwise.

It should be noted that a quotient simply means the number that obtained when division of numbers takes place.

In this case, the description of the transformation of z on the complex plane gives the quotient of 2 = 8cos30° + i sin30° and w = 2cos5° + i sin5° is to scale z by a factor of 1 and rotate it 5 degrees clockwise.

Answer:

a = 0.3

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

(5.3a - 0.8) - (1.6 - 4.7a) = 2a - (a - 0.3)

Step 2: Solve for a

Step 3: Check

Plug in a to verify it's a solution.

Here we see that 0.6 does indeed equal 0.6.

∴ a = 0.3 is a solution of the equation.

Answer:

A. 14

Step-by-step explanation:

A circle has 360 degrees. Lose a turn region is half, so 180.   360-180=180

If the answer is A, move two spaces region would be 56 degrees because 14*4=56

56+14=70

Move one space is 2 times move two spaces so 56*2=112

112+70=182

182+180=362

182 is the closest you can get to 180 without having a decimal.

Answer:

a) 0.0023

b) 0.007

c) 0.993

Step-by-step explanation:

The total number of marbles are;

5 + 10 = 15

Probability of red = 5/15

Probability of white = 8/15

Probability of 4 being red means, 4 will be white too;

Thus, the probability without replacement will be;

5/15 * 4/14 * 3/13 * 2/12 * 10/11 * 9/10 * 8/9 * 7/8 =

0.002331002331 which is approximately 0.0023

b. All white

Here, we have all the marbles selected being white

Thus the probability without replacement will be;

10/15 * 9/14 * 8/13 * 7/12 * 6/11 * 5/10 * 4/9 * 3/8

= 0.006993006993 which is approximately 0.007

c. At least one will be red

Mathematically, that will be;

1 - p(no red)

p(no red) = p(all white)

P(all white) = 0.007

hence P(no red) = 0.007

P(at least one red) = 1 - 0.007 = 0.993

Using the hypergeometric distribution, it is found that there is a:

a) 0.1632 = 16.32% probability that 4 will be red.

b) 0.0070 = 0.7% probability that all will be white.

c) 0.993 = 99.3% probability that at least one will be red.

The marbles are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem:

Item a:

This is P(X = 4), hence:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 4) = h(4,15,8,5) = \frac{C_{5,4}C_{10,4}}{C_{15,8}} = 0.1632[/tex]

0.1632 = 16.32% probability that 4 will be red.

Item b:

0 red, hence P(X = 0).

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 0) = h(0,15,8,5) = \frac{C_{5,0}C_{10,8}}{C_{15,8}} = 0.0070[/tex]

0.0070 = 0.7% probability that all will be white.

Item c:

This is:

[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]

From item b:

[tex]P(X \geq 1) = 1 - 0.007 = 0.993[/tex]

0.993 = 99.3% probability that at least one will be red.

Answer:

The sample size is    [tex]n = 68 [/tex]

Step-by-step explanation:

From the question we are told that

    The margin of error is  [tex]E = 5 \ years[/tex]

     The standard deviation is  [tex]\sigma = 22[/tex]

From the question we are told the confidence level is  94% , hence the level of significance is    

      [tex]\alpha = (100 - 94 ) \%[/tex]

=>   [tex]\alpha = 0.06[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.881[/tex]

Generally the sample size is mathematically represented as  

   [tex]n = [\frac{Z_{\frac{\alpha }{2} } *  \sigma }{E} ] ^2[/tex]

=>  [tex]n = [\frac{1.881 } *  22 }{5} ] ^2[/tex]

=>  [tex]n = 68 [/tex]

Answer:

a) 0.0004

b) 0.9604

c) 0.02

Step-by-step explanation:

When trying to find the probability of a sequence occurring you would simply need to multiply the probability of both of those things occurring together. Since the probability of an alternator failing is 0.02 then the probability of both failing would be...

0.02 * 0.02 = 0.0004

Now the probability of an alternator not failing is 0.98 (100% or 1 minus 0.02) therefore, the probability of both failing would be...

0.98 * 0.98 = 0.9604

Finally, the probability of one or the other failing would simply be the same as the probability of a single alternator failing which is 0.02

Answer:

the answer is D. $48

Step-by-step explanation:

All you have to do is divide 36 by 75%,

so put 36 ÷ 0.75 into your calculator and 48 is your answer!

You also could've done a process of elimination.

A, B, and C are clearly not the answer bc Jackie already has $36 in her purse and the question tells us that the $36 is only 75% of all the money she has, so we are looking for a number bigger than 36.

Soooo, D. is our only logical answer since it is $48 and the last time checked 48 is greater than 36.
