-x = 12

Step-by-step explanation:

x = -12

if you multiply both sides of the equation by -1, you get

-1x = -12 * -1

-x = 12

Answer:

12

Step-by-step explanation:

So what we know is that x is equal to negative 12. To make this easier you can say that -x is the same as -1 times x like shown below,

-1 × [tex]x[/tex]  is the same as -X

We can replace the x with -12 and a negative times a negative is a positive so the answer would be 12.

Suppose a jar contains 9 red marbles and 15 blue marbles. If you reach in the jar and pull out 2 marbles at random at the same time, find the probability that both are red.

Answers

Answer:

[tex] \frac{3}{23} [/tex]

Step-by-step explanation:

Since we start with 24 marbles, 9 of which are red, the probability of selecting a red marble is 9/24. The red marble is not put back, so there are now 23 marbles, 8 of which are red. It follows that the probability of selecting a second red marble is 8/23. So the probability of selecting a red marble and then another red marble is

[tex] \frac{9}{24} \times \frac{8}{23} = \frac{3}{8} \times \frac{8}{23} = \frac{3}{23} [/tex]

Answer:

x = 11, 3

Step-by-step explanation:

√(10x - 29) = x - 2

(√(10x - 29))² = (x - 2)²

10x - 29 = x² - 4x + 4

-10x + 29      -10x + 29

x² - 14x + 33  

(x - 11) (x - 3)

x - 11 = 0;     x - 3 = 0

State if three numbers can be the measure of a triangle.
12, 12, 20
10,3,7
7,7,11
24, 9, 12

Answers

Let the 3 sides of a triangle be a,b and c
For it to be a triangle then
a + b > c , a + c > b , b + c > a

12 , 12 , 20
12 + 12 > 20
24 > 20

12 + 20 > 12
32 > 12
Hence is a triangle

10,3,7
3 + 7 .....10
10 = 10
Hence is not a triangle since it does not satisfy the rules above

7,7,11
7 + 7 .... 11
14 > 11

11 + 7 ..... 7
18 > 7
Hence the figure formed is a triangle

24,9,12
9 + 12 .... 24
21 < 24
Hence is not a triangle

The rule is that for 3 numbers to form the sides of a triangle then the sum of any 2 of the numbers should be equal to the third

Hello can someone please answer this question i will mark you the Brainliest

Answers

Answer:

A) 310 cm²

Step-by-step explanation:

The surface area is the area of the two-dimensional surfaces of this three-dimensional figure.

Start by multiplying each 5x4 rectangle. There are four of them that are visible from the front.

4(5 · 4) 4(20) = 80 cm²

Now, find the surface area of the large rectangle in the back and the left side of the figure.

2(10 · 4) = 80 cm²

Find the surface area of the top of this figure.

10 · 5 = 50 cm²5 · 5 = 25 cm²

Find the surface area of the bottom of this figure (it's the same as the area of the top).

50 + 25 = 75 cm²

Add all of the surface areas together to find the total surface area of the figure.

80 + 80 + 75 + 75 = 310 cm²

2.813 m

Step-by-step explanation:

Looking at our angle we have an adjacent side & need to find the opposite side.

So tan θ = opp/adj

tan 17 = AB/9.2

AB = 9.2tan17

AB = 2.813 m

It would have to be 2.81m

The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of 98.27°F and a standard
deviation of 0.54°F. Using the empirical rule, find each approximate percentage below.
a. What is the approximate percentage of healthy adults with body temperatures within 1 standard deviation of the mean, or
between 97.73 °F and 98.81°F?

Answers

Answer: follow this you'll be able to solve it

Step-by-step explanation: mean = 98.11F

standard deviation = 0.56F

99.79 – 98.11 = 1.68 = 3 standard deviations

96.43 – 98.11 = –1.68 = –3 standard deviations

96.43F and ​99.79F are 3 standard deviations from the mean 98.11F.

By the empirical rule we know that 99.7% of the data lies within 3 standard deviation of the mean.

Approximately 68% of healthy adults in this group have body temperatures within 1 standard of the​ mean, or between 97.55F and 98.67F.

Answer:

t = 9 cm

Step-by-step explanation:

Use Pythagoras' Theorem: a² + b² = c²

(where a and b are the legs and c is the hypotenuse of a right triangle)

Given:

a = 12b = tc = 15a² + b² = c²

⇒ 12² + t² = 15²

⇒ 144 + t² = 225

⇒ t² = 225 - 144

⇒ t² = 81

⇒ t = √81

⇒ t = ±9

⇒ t = 9 only as length is always positive

Solution:

Pythagoras theorem can only be used in:

Right trianglesScalene right trianglesIsosceles right triangles.

Since this is a scalene right triangle, we can use Pythagoras theorem to solve the missing length of the triangle.

=> The formula for Pythagoras theorem is a² + b² = c².

Finding a, b, and c:

Let "a" be 12 cm and "b" be "t" cm."c" is the largest side of the triangle. This means that "c" is 15 cm, as it is the largest side of the triangle.

Setting up the equation:

a² + b² = c²=> 12² + t² = 15²

Simplifying the squares:

=> (12)(12) + t² = (15)(15)

Subtracting (12)(12) both sides:

=> t² = -(12)(12) + (15)(15)=> t² = -144 + 225=> t² = 81

Taking a square root both sides:

=> √t² = √81=> t = ±9

Since the length cannot be negative, the value of t must be positive.

The final answer is...

t = 9
