Choose the correct expression using the fewest number of bases possible that is equivalent to the current expression. Let x and y be positive integers and x>y. 11x11y=? Question 3 options: 11x+y 11x−y 11xy 11y−x

Answer:

Width = 5

Length = 13

Step-by-step explanation:

Area of a rectangle:

=> L x W = Area

After knowing this, we could find the factors of 65

=> 65 = 5 x 13, 1 x 65

So, the only way is 5 x 13.

So, Width = 5

     Length = 13

Let's check whether our answer is correct.

=> (3w - 2) * w  = 65

=> (3 (5) - 2) * 5 = 65

=> (15 - 2) * 5 = 65

=> 13 * 5 = 65

=> 65 = 65

So, our answer is correct.

Answer:

2x + y = 5 is the required equation.

Step-by-step explanation:

using slope intercept form,

i.e. y = mx + c

or, y =( -2 ) x + 5

or, y + 2x = 5

Answer:

5/13

Step-by-step explanation:

number of female students who have an A: 5

total number of female students: 13

The probability that a student who has an A is a female is 3/8

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]

where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

For two events A and B, by chain rule, we have:

[tex]P(A \cap B) = P(B)P(A|B) = P(A)P(B|A)[/tex]

where P(A|B) is probability of occurrence of A given that B already occurred.

We're specified a frequency table as:

                                                       Female                          Male

Has an A                                             3                                   5

Does not have an A                           8                                   13

We want to get P(Student is female if its given that student has an A).

Symbolically, we need P(Female | Has an A).

P(Student is female | Student has an A) = P(Student is female ∩ Student  has an A) / P(Student has an A)

Now, P(Student is female ∩ Student has an A) = n(Student is female∩ Student has an A) / n(all type of students) = 3/(3+5+8+13) = 3/29

Also, P(Has an A) =  n(has an A)/ n (All type of students) = n(has an A)/29

Since n(has an A) = number of students having A = females having A + males having A = 3+5 = 8

Thus,  P(Has an A) = 8/29

Thus, we get:

P(Female | Has an A) = P(Female ∩ Has an A) / P(Has an A) = [tex]\dfrac{3/29}{8/29} = \dfrac{3}{8}[/tex]

Thus, the probability that a student who has an A is a female is 3/8

Answer:

1740 N

Step-by-step explanation:

To find the force, you need to multiply the mass by the acceleration.

(60.0 kg) × (29.0 m/s²) = 1740 N

The force will be 1740 N.

Supplementary angles are those angles which add upto 180°. They may or may not be linear pair.

We have,

Let,

Then,

➝ x + x + 2° = 180°

➝ 2x + 2° = 180°

➝ 2x = 178°

➝ x = 89°

Other angle = x + 2° = 91°

Answer - 89° and 91°

⚘ Hence, solved !!

━━━━━━━━━━━━━━━━━━━━

Answer:

Step-by-step explanation:

Let the numbers are x, x+1

The sum of supplementary angles is 180°

X+x+1=180

2x+1=180

2x=180-1

2x=179

X=179/2

X=89.5

X+1=89.5+1=90.5

The integers are 89.5,90.5

Answer:

P(red or blue) = [tex]\frac{7}{16}[/tex].

Step-by-step explanation:

We have to find P(A or B), if A and B are independent events for one action, such as spinning a four-color spinner once.

Firstly, as we know that the formula for finding P(A or B) is given by;

P(A or B) = P(A) + P(B) - P(A and B)

Since it is stated that event A and B are independent, this means that there is no dependence of any one event on another event, so;

P(A and B) = P(A) [tex]\times[/tex] P(B)

Now, we can find P(A or B) = P(A) + P(B) - P(A) [tex]\times[/tex] P(B); is we know that the probabilities of happening of both events.

Similarly, P(red or blue) = P(red) + P(blue) - P(red) [tex]\times[/tex] P(blue).

Since the event is spinning a four-color spinner once and assuming there are four different colors, so the probability of wheel stopping on each color is ([tex]\frac{1}{4}[/tex]).

So, P(red or blue) = [tex]\frac{1}{4} +\frac{1}{4} -(\frac{1}{4} \times \frac{1}{4} )[/tex]

                             = [tex]\frac{2}{4} -\frac{1}{16}[/tex]  = [tex]\frac{7}{16}[/tex].

Answer:

-2,10

Step-by-step explanation: i took the test and when doing this you only change the y  but keep the x.

The required simplified value of x, y,  and z is 2, 2, and 2.

Given that,
The system of the equation is given
4x - 2y +z = 6,
-2x + y = -4,
3y - 2z = 4
And also x= y= z

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Since, x = y = x
taking any one equation
4x - 2y +z = 6
Now,
4x - 2x + x = 6
3x = 6
x = 2

Thus, the required simplified value of x, y,  and z is 2, 2, and 2.

Hence, the function that best represents the data is:

Option C.

y=26.9x-1.3

Step-by-step explanation:

Considering the situation described, it is found that a linear model best represents the data, because there is a relatively consistent additive rate of change.

In this problem, when the input changes by 2, the output always increases between approximately 50 and 60, that is, the same values, hence a linear model best represents the data, because there is a relatively consistent additive rate of change.

Answer:

13/40

Step-by-step explanation:

5/8 - 3/10

get a common denominator of 40

5/8*5/5 - 3/10 *4/4

25/40 - 12/40

13/40

Answer:

13/40

Step-by-step explanation:

We can find the lowest common multiple of 8 and 10, so that the two fractions will have the same denominator.

The LCM of 8 and 10 is 40, so we can rewrite 5/8 as 25/40 by multiplying the numerator and denominator by 5, and rewrite 3/10 as 12/40 by multiplying the numerator and denominator by 4.

This makes the subtraction easier, as we find 25/40 - 12/40.

We get (25-12) / 40, or 13/40.

Answer:

A

Step-by-step explanation:

The difference of squares formula is a² - b² = (a + b)(a - b). We want this polynomial to be in the form a² - b². We notice that x² and 49 are perfect squares already which means that we don't need the x term. To get rid of it, its coefficient must be 0 because 0 times anything is 0, thus the x term will be removed and we'll be left with x² - 49 which is a difference of squares.

Answer:

[tex]\Large \boxed{{n=5}}[/tex]

Step-by-step explanation:

10^2n-6 = 10,000

Make 10,000 with base 10.

10^2n-6 = 10^4

Cancel same bases.

2n-6 = 4

Add 6 to both sides.

2n = 10

Divide both sides by 2.

n = 5

Answer:

[tex]\huge\boxed{n = 5}[/tex]

Step-by-step explanation:

[tex]10^{2n-6} = 10,000[/tex]

Write 10,000 as a base of 10

[tex]10^{2n-6} = 10^4[/tex]

Comparing both sides , we get:

[tex]2n - 6 = 4[/tex]

Adding 6 to both sides

2n = 4+6

2n = 10

Dividing both sides by 2

n = 10 / 2

n = 5
