Identity the slope and y intercept

Answers

Answer:

3,-2

Step-by-step explanation:

From the attached graph we need to find the slope and the y Intercept . The data that can beextracted from the graph is ,

The line passes through (0,3) and (1.5,0) .

Hence the y Intercept here is 3 , since the graph cuts y axis at 3 units above the x axis.

Slope :-

→ m = 3 - 0 / 0 - 1.5

→ m = 3/-1.5

m = -2

Hence the y Intercept is 3 and the slope is (-2) .

what is the geometric mean of 14 and 6

Answers

Answer:

8

Step-by-step explanation:

The geometric mean of two numbers 14 and 6 is 2√21.

What are arithmetic and geometric mean?

An arithmetic mean can be obtained by taking the sum of all the numbers and dividing it by the number of numbers.

In the case of geometric mean, we multiply the numbers and raise them to the reciprocal of a total number of numbers.

Given, Two numbers 14 and 6.

Now, 14×6 = 84.

Now, we have to take the square root of 84 as we have two numbers.

Therefore, The geometric mean of 14 and 6 is,

= √(84).

= 2√21.

Find the distance of the hypotenuse.

Answers

Answer:

A) 7.8

Step-by-step explanation:

The side lengths of the triangle are 5 units and 6 units.

Using the Pythagorean Theorem, a²+b²=c², we can find the hypotenuse, c, given side lengths a and b:

a²+b²=c²

5²+6²=c²

25+36=c²

61=c²

√61=c

7.81≈c

Therefore, the hypotenuse is about 7.81 units, making A the closest choice.

x+3/x-2 - 1-x/x =17/4
find the x with methods​

Answers

Answer:

The solution set is {-2/9, 4).

Step-by-step explanation:

(x + 3)/(x-2)  - (1-x)/x = 17/4

Multiply through by the LCD ( = 4x(x - 2):

(x + 3)4x - 4(1 - x)(x - 2) = 17x(x - 2)

4x^2 + 12x - 4(x - 2 - x^2 + 2x) - 17x^2 + 34x = 0

4x^2 + 12x - 4x + 8 + 4x^2 - 8x - 17x^2 + 34x = 0

-9x^2 + 34x + 8 = 0

We need 2 numbers  whose product = -72 ( -9 * 8) and whose sum is 34.

These are +36 and -2, so we write:

-9x^2 + 36x - 2x + 8 = 0

-9x(x - 4) - 2(x - 4) = 0

(-9x + 2)(x - 4) = 0

x = -2/9, 4.

Solution :

The given figure consists of two shapes that are a triangle and a square . To find the total area of the figure we will first find the area of the triangle then that of the square and add them .

Let's work on this ,

Area of triangle [tex]\sf\implies\::\dfrac{1}{2}\:\times\:base\:\times\:height[/tex]

In the given figure the base of the triangle is 12 inches and it's height is 8 inches .

[tex]\sf\implies\::\dfrac{1}{2}\:\times\:12\:\times\:8[/tex]

6 × 8 48 inches²

Now lets find the area of the square ,

Area of square = Side × Side12 × 12144 inches²

Total area of the figure

Area of triangle + Area of square 48 + 144192 inches²

Xander has $15 and make $4 a day. Aislyn has $10 and makes $4 a day. When will they have the same amount of money?

Answers

Answer: Never because Aislyn cannot catch up if they make the same amount of money per day.

Step-by-step explanation:

Assume that the day they will have the same amount of money is x.

The amount that Xander will have on that day is:

= 15 + 4x

The amount that Aislyn will have on that day is:

= 10 + 4x

Equate the two fractions:

15 + 4x = 10 + 4x

15 - 10 + 4x = 4x

5 = 4x - 4x

5 = 0x

What this means is that they will never have the same amount of money because they are increasing by the same amount so Aislyn will never catch up.

What is the measure of angle A?

A.) 50 degrees
B.) 40 degrees
C.) 45 degrees
D.) 55 degrees

Answers

To find:-

The measure of angle A.

Solution:-

[tex]{\boxed{\mathcal{\red{B.\:Angle\: A \:=\: 40° \:}}}}[/tex]✅

Step-by-step explanation:-

We know that,

[tex]\sf\pink{Sum\:of\:angles\:of\:a\:triangle\:=\:180°}[/tex]

➪ 90° + x + 51 + x + 41 = 180° ( 90° since it is a right-angled triangle )

➪ 2 x + 182° = 180°

➪ 2 x = 180° - 182°

➪ x = [tex] \frac{ - 2}{2} [/tex]

➪ x = -1°

Now,

Measure of angle A = x + 41

= (-1°) + 41

= 40°

[tex]\sf\red{Therefore, \:the\: measure\:of \:∠\: A\: is \:40°.}[/tex]

To verify:-

90° + (-1°) + 41 + (-1°) + 51 = 180°

✒ 182°- 2°= 180°

✒ 180° = 180°

✒ L. H. S. = R. H. S.

5) The coordinates of A are (1, 0) and the coordinates of B are (2, 6), what are the coordinates of the midpoint of AB?

Answers

Answer:

The coordinate of the midpoint of AB is (1.5, 3).

Step-by-step explanation:

The midpoint of AB is the point that is the same distance between both points A and B. In order to find the midpoint, add the x and y values of points A and B respectively, and divide the sum by 2 to find the midpoint of AB. [tex]\frac{1+2}{2} = 1.5[/tex], so the x value of the midpoint is 1.5. [tex]\frac{0+6}{2} = 3[/tex], so the y value of the midpoint is 3. You'll get that the coordinate of the midpoint of AB is (1.5, 3).

What is the probability of flipping a coin 85 times and getting tails 50 times or

A. 33.2%
B. 0.4%
C. 95.9%
D. 99.8%

Answers

Answer:

C: 95.9%

Step-by-step explanation:

To find this, we shall be using the cumulative binomial probability calculator

As we know, the probability of getting a head or a tail in a throw of a coin is same with a value of 0.5

So, we want to find the probability of getting tails 50 times or fewer which means the probability of getting at most 50 tails

So we have the parameters as follows;

P( x ≤ 50)

n = number of trials = 85

p = probability of success = 0.5

r = number of success = 50

Using the parameters in the cumulative binomial probability calculator, we have the value as ;

0.9589 = 95.9%
