Answer:

3/4 + 3/5 = 1 7/20

Step-by-step explanation:

5 x 4 = 20

3/4 = 15/20

3/5 = 12/20

15/20 + 12/20 = 27/20 = 1 7/20

Answer: 1 7/20 (one and seven-twentieths)

Step-by-step explanation:

1) 3/4 = 15/20 and 3/5 = 12/20

2) 15/20 + 12/20 = 27/20

3) 27/20 = 1 7/20

Answer:

the tip amount is $12

Step-by-step explanation:

The computation of the tip amount is shown below:

But before that rounded the dinner bill to the nearest ten dollars i.e. $80

Now the tip amount is

= Dinner bill × tip percentage

= $80 × 15%

= $12

Hence, the tip amount is $12

Answer:

That’s easy it is 282

Step-by-step explanation:

He will now have 282 bucks altogether.

Step-by-step explanation:

We already know that he has 237 bucks before his birthday, but now he has an additional 45 bucks that he got from his birthday. With this, you can create an equation that looks like this: 237+45. You then solve the equation by adding 45 to 237, which gets you 282 bucks altogether.

Answer:

(3x+1) (x-1)

Step-by-step explanation:

.................

The factored form of 3x² - 2x - 1 is (3x + 1)(x - 1).

To factor the quadratic expression 3x² - 2x - 1, we can look for two binomials that multiply together to give the original expression.

We need to find two binomials in the form (ax + b)(cx + d) that, when multiplied, result in 3x² - 2x - 1.

To factor this expression, we need to find two numbers that multiply to give 3 (the coefficient of x² term) and add up to -2 (the coefficient of the x term).

By trial and error or using factoring techniques, we find that the factors are (3x + 1) and (x - 1).

Therefore, the factored form of 3x² - 2x - 1 is:

(3x + 1)(x - 1).

Answer:

Step-by-step explanation:

The value of P(x>6) is 1/5.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Given that A distribution is given as X ~ U(0, 12).

We need to find the value of  P(x > 6)

The probability density function of the uniform distribution is defined as:

f(x)=1/b-a, a<x<b

a=0 and b=12

f(x)=1/12 , 0<x<12

The required probability is P(x>6)

Now P(x>6)= [tex]\int\limits^2_6 {f(x)} \, dx[/tex]

P(x>6)=(12/12-6/12)

=1-1/2

=1/2=0.5

Hence, the value of P(x>6) is 1/5.

Which translation maps the vertex of the graph of the function f(x) = x2 onto the vertex of the function g(x) = –8x + x2 + 7 ?

left 4, down 9

left 4, up 23

right 4, down 9<<<<<<< CORRECT

right 4, up 23

The translation should be right 4 units and down 9 units.

First, we need to find the vertices of both functions.

for f(x) = x^2 the vertex is at (0, 0), as we already know.

For g(x) = -8x + x^2 + 7 the x-value of the vertex is at:

x = -(-8)/(2*1) = 4

Evaluating g(x) at x = 4 we get:

g(4) = -8*4 + 4*4 + 7 = -9

So the vertex is at (4, -9).

To go from (0, 0) to (4, -9) we need to move right 4 units and down 9 units, so the correct option is the third one.

Answer:

Step-by-step explanation:

Given that the total number of people protesting is 81. These people are either male - Student or non student or Females (student or non students)

Given that there are 36 males then number of females

= 81 - 36

= 45

If there are 18 females non students then the number of females protesting that are students

= 45 - 18

= 27

Answer:

851,968

Step-by-step explanation:

26*8*8*8*8*8= 851,968

From the combination of codes, 851,968 employee ID codes can be generated.

Given,
Employee ID codes can be generated.
Each code will have one letter followed by five digits. The digits 2 and 6 will not be used. So, there are 26 letters and 8 digits that will be used.
The number of employee codes to be determined.

In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In a combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.

Required number of  codes = 26 * 8 * 8 * 8 * 8 * 8
                                         = 851,968

Thus, from the combination of codes, 851,968 employee ID codes can be generated.

Answer:

45, 45 and 90 degrees

Step-by-step explanation:

Complete question

The measures of angles X and Y are the same, x degrees. The measure of angle Z is twice the measure of angle Y. Find the measure of each angle

Let the sum of the angles be 180 degrees

X = x

Y = x

If Z is twice the measure of angle Y, then;

Z = 2x

Taking the sum

<X + <Y + <Z = 180

x+x+2x = 180

4x = 180

x = 180/4

x = 45

since Z = 2z

Z = 2*45

Z = 90

Hence the measure of the angles X, Y and Z are 45, 45 and 90 respectively
