hey whats the answer to this ? will mark brainliest if correct

Answer:

Use the x method

Step-by-step explanation:

Move the 10 over to the other side and get x^2 - 3x -10 = 0 and solve by finding two numbers that add up to negative 3 but multiply to -10 which would be -5 and 2 so the binomials are (x-5)(x+2)

Answer:

x^2 - 3x = 10

Step-by-step explanation:

Move all terms to the left side.

Use the sum product pattern.

Factor (x-5)(x+2) = 0

Create two separate equations,

x - 5 = 0, and x + 2 = 0

Rearrange and isolate the variable.

x = 5

x = -2

Answer:

d. 3,200

Step-by-step explanation:

If the total population consists of 32,000 people, a sample of the population selected will consist of a number equal or less than 32,000 people.

From the given options, the only option that matches the above explanation is "D" which is less than 32,000 people.

Therefore, the correct answer choice is D. 3,200.

Answer:

The probability of  the percentage of thefts in a random sample of 400 would be greater than or equal to 3 is  given by  P (z> 1.09)   = 0.1379

Step-by-step explanation:

The statistic

z= p^- p / √pq/n

is used to measure the difference between the sample and population proportions.

Here p^= 12/400= 0.03

p= 0.022               q= 1-0.022=0.978

 and n=400

Putting the values

Z= 0.03-0.022/√0.022(1-0.022)/400

Z= 0.008/√0.022(0.978)/400

Z= 0.008/0.00733

z= 1.090

We have to find the probability of  the percentage of thefts in a random sample of 400 would be greater than or equal to 3

or

Mathematically

P (z> 1.09)= 1- P (z≤1.09)

                  = 1- 0.8621   ( from the z area table)

                   = 0.1379

So the answer is no.

Answer:

x=15

Step-by-step explanation:

So we know 4x plus 8x gets a total of 180 degrees (since a straight line is 180 degrees). Combine 4x and 8x to get 12x. To find x, divide 12 from 180. 180/12 is 15.

Answer:

x² + y² - 8x -14y - 105 = 0

Step-by-step explanation:

The centre of the circle is (-7,0) and the radius is (4,7) . Firstly let's find the radius using Distance formula .

=> D = √{ (-7-4)²+(0-7)²}

=> D = √ 11² + 7²

=> D = √ 121 +49

=> D = √170

Now using the standard equation of circle ⭕ ,

=> ( x - h)²+(y-k)² = r²

=> ( x - 4)²+(y-7)²= (√170)²

=> x² + 16 -8x + y² + 49 -14y = 170

=> x² + y² -8x -14y = 170 -65

=> x² + y² - 8x -14y - 105 = 0

Answer:

Area of given figure = 48.28 unit² (Approx.)

Step-by-step explanation:

Given:

Length of parallel lines are 10 , 4 respectively

Diameter of semi-circle = 4

Height of parallelogram = 6

Find:

Area of given figure

Computation:

Radius of semi-circle = Diameter of semi-circle / 2

Radius of semi-circle = 4 / 2

Radius of semi-circle = 2

Area of given figure = [1/2][Sum of parallel line][Height] + [πr² / 2]

Area of given figure = [1/2][10 + 4][6] + [(3.14)(2)² / 2]

Area of given figure = [1/2][14][6] + [(3.14)(4)/ 2]

Area of given figure = 42 + 6.28

Area of given figure = 48.28 unit² (Approx.)

Answer:

This question can be solved in two ways but we're gonna go with the Formula Method

For the sum of terms

Sn = n/2[2a+ (n-1)d]

Given

Sn=50

n=10terms

Substituting

50=10/2[2a + (10-1)d]

50=5[2a + 9d]

10=2a + 9d......(i)

Now the Second Statement...

""The Fifth term is 3x the second term""

What is the Fifth term(T5) of an Ap?

Using the general formula for nth term of an Ap

Tn = a+(n-1)d

T5 = a +(5-1)d

T5= a + 4d

For Second term (T2)

T2=a + (2-1)d

T2 = a + d

"It said... T5 = 3T2

ie a + 4d = 3(a + d)

a + 4d = 3a + 3d

Collecting Like terms

2a=d........(ii)

Bring down both equations

10=2a + 9d...(i)

2a = d...(ii)

Substituting d=2a into Equation (i)

10 = 2a + 9(2a)

10=2a + 18a

10=20a

a=10/20

a=1/2

Since d=2a

d=2(1/2)

d=1.

Now

We're asked to Find the Sum of the First 100terms

n=100

a=1/2

d=1

Sn =n/2[2a+(n-1)d]

Sn= 100/2[2(1/2) + (100-1).1)

Sn= 50[1 + 99]

Sn = 50(100)

Sn = 5,000.

Answer:

16.3°

Step-by-step explanation:

Cos x = adjacent side/hypotenuse

         = 24/25

x = arccos (24/25) = 16.3°

You must memorize the definitions of the trig functions and then this type of problem is easy.  OK?

Answer:

c

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

the probability it would snow is 0.07 or 7%. this is quite low. so, it is unlikely that it would snow

Answer:

-2x - 10

Step-by-step explanation:

-2 x X = -2x

-2 x 5 = -10

Put them together to get:

-2x - 10

Answer:

-2(x) or (-2×x)

then you get = -2x

then you take

-2×+5 or (-2×5) you'll get = -10

last but not least you join the equation

and the answer will be

= -2x-10

Answer:

6 √15

Step-by-step explanation:

a^2 + b^2 = c^2

plug in your values

(6*6) + (b^2) = (24*24)

solve your exponents

36 + b^2 = 576

subtract 36 from both sides

b^2 = 540

find the square root of both sides

√b^2 = b

√540 = 6√15

b= 6√15

Answer:

$27

Step-by-step explanation:

We have to find 6% of $450. We can make an expression and solve it:

6/100•450

We can cancel out factors now:

3/50•450

Now we'll cancel out 50 and 450:

3x9=$27

And that's your answer! Hope this helps =)
