Scores on a test are normally distributed with a mean of 200 and a standard deviation of 12. Find each probability

Answer:

a is less than or equal to 35 since 35 is the highest value that can be gotten

Answer:

k = 12

Step-by-step explanation:

-5/6k = -10

Multiply both sides by 6k

-5/6k x 6k= -10 x6k

simplify

-5 = -60k

Switch sides

-60k = -5

Divide both sides by -60

-60k/-60 = -5/-60

Simplify to get your answer of

1/12 or 12

Answer:

He is 42 years old.

Step-by-step explanation:

3 x 14 = 42

The 3 is for how many times older Ishaan is.

The 14 is how many years older than Christopher Isahaan is.

If you need to find Isaahan's age, just multiply 2 x 14, which is 28.

Isahaan is 28 years old, and Christopher is 42 years old.

Answer:

V = 432 m³

Step-by-step explanation:

The volume (V) of a prism is calculated as

V = Ah ( A is the area of the base and h the height )

A = [tex]\frac{1}{2}[/tex] bh ( area of triangular base, with b the base, h the perpendicular height)

Here b = 16 and h = 6 , then

A = [tex]\frac{1}{2}[/tex] × 16 × 6 = 8 × 6 = 48 m²

Then

V = 48 × 9 = 432 m³

Answer:

(10/3, -1)  

Step-by-step explanation:

So there are two different ways.  

First you could address for y and fitting it into the number cruncher. one condition for y1 and another for y2. At that point go second follow and press 5 and afterward press enter multiple times to discover the convergence.  

the subsequent path is to tackle by hand. I would recommend address the primary condition for y and attachment the condition tackled for y into the other condition. so y = - 3x + 9 and 3x-5y=15. At that point you could do 3x - 5(- 3x+9) = 15. At long last address for x and plug in x into the two conditions to check whether you get a similar y esteem.  

The appropriate response ought to be (10/3, - 1)

Answer:

x = 3 1/3, x = -1.

Step-by-step explanation:

3x + y = 9

3x - 5y = 15

Subtract second equation from the first to eliminate the 3x :

3x - 3x + y - (-5y) = 9 - 15

6y = -6

y = -1.

Plug y = -1 in first equation:

3x + -1 = 9

3x =  10

x = 10/3 = 3 1/3.

Answer:

y=10

Step-by-step explanation:

x=k/y

constant of proportionality

k=xy

k=5*6

k=30

therefore x=30/y

if x=3 y=?

y=30/3

y= 10

Answer:

Step-by-step explanation:

The first one is actually 0 I think. The instantaneous ROC at x=1 should also be 0. The last one should be correct.

Basically, the ROC for the first one is 0 because the y value at the start and end of the interval is the same, so the change is the same. However, for the instantaneous ROC at x = 0, you look at the graph and realize that if you find the derivative at that point, it is 0.

Step-by-step explanation:

6g - 8 - 8g - 3

-2g - 11

Answer:

-2g - 11

Step-by-step explanation:

2(3g - 4) - (8g + 3)

Use the distributive property to multiply 2 by 3g - 4.

6g + 2(-4) - (8g + 3)

6g - 8 - (8g + 3)

Find the opposite of 8g + 3.

6g - 8 - 8g - 3

Combine like terms.

-2g - 8 - 3

Subtract 3 from -8 to get -11.

-2g + 11

The expression equivalent to 2(3g - 4) - (8g + 3) is -2g - 11.

Answer:

The area of triangle AED = (x^2-xy)/2

Step-by-step explanation:

Mathematically, the area of a square is the product of its side lengths

Thus, if the area is x^2; then the side of the square measures x

So each of the side of the square has a measure x units

Now, for the base of the square;

EC = ED + DC

x = ED + y

ED = x - y

Mathematically, the area of a triangle is the product of the base and the height of the triangle divided by 2

The height here is x and the base is (x-y)

We have this as;

Area of triangle AED =

1/2 * x * (x-y)

= (x(x-y))/2

= (x^2-xy)/2

Answer:

The answer is B.

Step-by-step explanation:

You can solve this problem by plugging in 2 for x in the given equations.

2(2) - 3 = 19 is false

3(2) + 2 = 8 is true

4(2) - 4 = -4 is false

5(2) + 1 = 10 is false

Answer:

20

Step-by-step explanation:

A data is given and the mean of data is 19.6 .The data is ,

12 , 16 , 22 , x , 28 .

We know that the mean is sum of observations divided by Total number of observations . So that ,

⇒ 12 + 16 + 22 + x + 28/ 5 = 19.6

⇒ 78+x/5 = 19.6

⇒ 19.6 × 5 = 78 + x

⇒ 78 + x = 98

⇒ x = 98 - 78

⇒ x = 20

Answer:

120

Step-by-step explanation:

4x, 7x, 9x

Answer:

a=55

b=55

c=125

d=125

e=55

f=55

g=125

Step-by-step explanation:

Answer:

∠a = 55°, ∠b = 55°, ∠c = 125°, ∠d = 125°, ∠e = 55°, ∠f = 55°, ∠g = 125°

Step-by-step explanation:

straight lines form 180°:

125° + ∠a = 180°

=> ∠a = 55°

verticle angles are congruent:

∠c = 125°

∠b ≅ ∠a => ∠b = 55°

When two line are parallel:

same side interior angles are congruent:

∠g ≅ ∠c => ∠g = 125°

∠e ≅ ∠a => ∠e = 55°

∠d = 125°

∠ f ≅ ∠b => ∠f = 55°

264,319

Step-by-step explanation:

A difference is a subtraction problem.

Subtract 214,991 from 479,310.

479,310 - 214,991 = 264,319

=====================================================

Explanation:

We'll apply this formula

A = P*e^(r*t)

where,

In this case, we have

Again we won't type "2.718..." for 'e', and we'll just type it into the calculator as shown below. That way the calculator can handle the digits instead.

So...

A = P*e^(r*t)

A = 500*e^(0.06*6)

A = 716.66470728026

A = 716.66 dollars is the final answer
