Answer:

x=3

y=5

Step-by-step explanation:

5x+3(0) The y is zero because in the x-intercept the y is zero (same for x)

5/5x=15/5

x=3

5(0)+3y=15

3/3y=15/3

y=5

Step-by-step explanation:

I found the graph. All you needed to do was switch the red and blue line. I put a screenshot of the correct answer on I-Ready as well as the graph I had found.

The system of equations needed to solve the given equations is . Thus, the correct graph is the top-right graph. Its plotted below.

An equation usually consists of equality of two mathematical expressions. Let it be [tex]A = B[/tex]. If we take them to be equal to third variable, then:

[tex]A = B = C[/tex] type of equation is obtained.

We can then take it as system of two equations as:

[tex]A = C\\B = C[/tex]

Solution to this system will give us the solution to the considered equation

For a solution to be solution to a system, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs.

For the given case, we are given that:

[tex]2^x-1=x+2[/tex]

Taking these two mathematical expression equal to 'y', we get:

[tex]2^x-1=x+2 = y[/tex]

or

[tex]y = 2^x - 1\\and\\y= x+2[/tex]

Plotting these two functions on the X-Y plane, the common point of these curves is the common value which can satisfy both the equations simultaneously, and thus, being the solution to the considered system of equations.

Thus, the solutions are those two points that are intersections of those two curves.

y = 3

Step-by-step explanation:

39 = 13y

y = 3 (explanation: by dividing 13)

Check answer:

39 = 13(3)

39 = 39

Answer:

y = 3

Step-by-step explanation:

39 = 13y

Divide each side by 13

39/13 = 13y/13

3 = y

Check

39 = 13*3

39 = 39

Our solution checks

Step-by-step explanation:

y = -0.25x + 2

The slope is the coefficient of x, which is -0.25.

y-intercept is the constant term, which is 2.

When y = 0, -0.25x + 2 = 0, -0.25x = -2, x = 8.

=> x-intercept = 8.

Step-by-step explanation:

The length of the remaining rope is 41.5 inches.

A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

Harold cut 18 and a half inches off a rope that was 60 inches long.

Let the remaining length of the rope be x.

This can be written as,

⇒ [tex]x=60-18.5[/tex]

⇒ [tex]x=41.5[/tex]

Hence we can conclude that the length of the remaining rope is 41.5 inches.

Step-by-step explanation:

Answer:

Jada is wrong. For example, say Jada is drawing scaled versions of a 10x10 yard square. In her first drawing, 1 centimeter = 1 yard, so the drawn square is 10x10 centimeters. In her second drawing, 1 centimeter = 2 yards, which is greater, like the problem says. This drawing will be only 5x5 centimeters, meaning the lengths will be smaller as each centimeter represents a greater number of yards.

Answer:

No, because a mean is the average.

Step-by-step explanation:

Consider the following example:

The set is:

19, 23, 11, 31

if you add all these up you get 84.

Then you divide by 4 and get 21. So, 21 is the mean but, when you look at the set of numbers, 21 is not there. So, the same goes for any number, a number can still be the mean even if it is not in the set.

Answer

a. 0.856

b. 0.78071

c. It is not unusual

d. 13.65 years old

Step-by-step explanation:

The life span of a domestic cat is normally distributed with a mean of 15.7 years and a standard deviation of 1.6 years.

We solve this question using z score formula:

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation.

a. Find the probability that a cat will live to be older than 14 years.

For x > 14 years

z = 14 - 15.7/1.6

z = -1.0625

Probability value from Z-Table:

P(x<14) = 0.144

P(x>14) = 1 - P(x<14) = 0.856

b. Find the probability that a cat will live between 14 and 18 years.

For x = 14 years

z = 14 - 15.7/1.6

z = -1.0625

Probability value from Z-Table:

P(x = 14) = 0.144

For x = 18 years

z = 18 - 15.7/1.6

z= 1.4375

Probability value from Z-Table:

P(x = 18) = 0.92471

The probability that a cat will live between 14 and 18 years is calculated as:

P(x = 18) - P(x = 14)

0.92471 - 0.144

= 0.78071

c. If a cat lives to be over 18 years, would that be unusual? Why or why not?

For x > 18 years

z = 18 - 15.7/1.6

z= 1.4375

Probability value from Z-Table:

P(x<18) = 0.92471

P(x>18) = 1 - P(x<18) = 0.075288

Converting this to percentage:

0.075288 × 100 = 7.5288%

Hence, 7.5288% of the cats live to be over 18 years. Hence, it is not unusual.

d. How old would a cat have to be to be older than 90% of other cats?

From the question above, 10% of the cats would be older than 90% of other cats.

Hence, we find the z score of the 10th percentile

= -1.282

Hence,

-1.282 = x - 15.7/1.6

Cross Multiply

-1.282 × 1.6 = x - 15.7

- 2.0512 = x - 15.7

x = 15.7 -2.0512

x = 13.6488 years old

Approximately = 13.65 years old

Answer:

  5 1/2 cm

Step-by-step explanation:

The perimeter is the sum of the given lengths (in cm):

  P = (1 1/5) +(1 3/4) +(1 1/4) +(1 3/10)

  = (1 + 1 + 1 + 1) +(2/10 + 3/4 + 1/4 +3/10)

  = 4 + 1 5/10

  = 5 1/2

The perimeter of the figure is 5 1/2 cm.

We need to find the value of the expression :

[tex]64\dfrac{5}{6}[/tex]

It is in the form of a mixed fraction. We can simplify it as follows :

[tex]64\dfrac{5}{6}=\dfrac{64\times 6+5}{6}\\\\=\dfrac{389}{6}[/tex]
