Answer:

Step-by-step explanation:

Any equation, for example 2r =2/3

The probability that the mean of this sample is less than 105.4 is 14.46%

The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } \\\\x=raw\ score, \sigma=standard\ deviation, \mu=mean,n\ is\ sample\ mean\\\\\\Given\ that\ \sigma=45,\mu=124.5,n\ =36,hence:\\\\For\ x<105.4:\\\\z=\frac{105.4-124.9}{45/\sqrt{36} }=-1.06[/tex]

From the normal distribution table, P(x < 105.4) = P(z < -1.06) = 0.1446 = 14.46%

The probability that the mean of this sample is less than 105.4 is 14.46%

Answer:

x>= 11 or x>10

Step-by-step explanation:

Absolute value can be used to represent the positive counterpart of a negative number. In this case, we are asked to find a number that is less than -10, meaning from -11 to negative infinity. Since we are asked to take absolute value, we would take |-11| which equals 11, and |-∞| = ∞.

So Amy graphed a value on the number line that is greater than or equal to 11, or any value greater than 10.

*Infinity is not a real number, it represents the largest number possible, which doesn't exist since numbers can continue on forever, so it can be disregarded.*

Answer: 45 degrees angle

Answer:

  0, 4, 8

Step-by-step explanation:

As you have noticed, the difference between the end values of x is 20-4 = 16, and the differences in each interval are 4.

The difference between the end values of y is 12 -(-4) = 16, so the differences in each interval will also be 4.

The missing table values are 0, 4, 8. The completed table is ...

  [tex]\begin{array}{cccccc}x&4&8&12&16&20\\y&-4&0&4&8&12\end{array}\right][/tex]

Answer:

-9y + 7 = -9y + 6

Step-by-step explanation:

-9y + 7 = -9y + 6

Has no solution

add 9y to both sides

7 = 6 which is false

therefor no y exists that can result in a solution

Answer:

Interest rate (r ) = 0.035 or 3.5%

Step-by-step explanation:

Given the principal amount of $1,800, and an interest payment of $378 earned in 6 years:

Use the simple interest formula and algebraically solve for variable, interest rate, r :

I  =  P × r × t

Where:

I = interest payment = $378

P = principal amount = $1,800

t = time (in years) = 6

r = interest rate

Divide both sides by P × t to isolate r :

[tex]\displaytext\sf{\frac{I}{P\:\times\:t}\:=\:\frac{P\:\times\:r\:\times\:t}{P\:\times\:t}}[/tex]

[tex]\displaytext\sf{interest\:rate\:(r)\:=\:\frac{I}{P\:\times\:t}}[/tex]

Substitute the given values into the formula for the interest rate:

[tex]\displaytext\sf{interest\:rate\:(r)\:=\:\frac{378}{1800\:\times\:6}\:=\:\frac{378}{10800}}[/tex]

Interest rate (r ) = 0.035 or 3.5%

Therefore, the interest rate is 3.5%.

Answer:

x=33

Step-by-step explanation:

The sum of the angles of a triangle is 180

23+124+x = 180

147+x =180

x = 180-147

x =33

Answer: 33

Step-by-step explanation:

A triangle is equal to 180 degrees. So you add 124 and 23 to get 147. You would then subtract 180-147=33 and then you have your answer. Hope this helps!

Answer:

the last year the eschool has 2248 books

Step-by-step explanation:

2284-36=2248

Answer:

2,248=2,284-36b

Step-by-step explanation:

since the library acquired(added) 36 books the library now has a total of 2,284 books.

To find out how many books the library had before they added 36 books you need to set up a simple equation.

2,284-36=2248

since you now know that before summer the library had 2,248 books you would write an equation and when you solve it you should get 2,248. The equation should be 2,248=2,284-36b. b representing the total number of books that were added.

Answer: WHERE IS THE DIAGRAM

g(x) = 2x^2

for g(- 4), you just plug in - 4 for x

g(- 4) = 2(- 4)^2

g(- 4) = 2(16)

g(- 4) = 32

Answer:

g(-4) = 32

Step-by-step explanation:

Given the quadratic function, g(x) = 2x², finding the output value given g(-4) involves substituting the value of the input, x = -4, into the function.

g(x) = 2x²

g(-4) = 2(-4)² = 2(-4)(-4)

g(-4) = 2(16)  

g(-4) = 32

Therefore, g(-4) = 32.

Answer:

x = 7 and y = -8      ordered pair is (7, -8)

Step-by-step explanation:

0.1x + 0.3y = - 1.7

0.3x - 0.5y = 6.1

Solving the first equation for x    0.1x = -0.3y - 1.7

                                                     0.1x/0.1 = -0.3y/0.1 - 1.7/0.1

                                                          x = -3y - 17

Substitute into the second equation.

0.3(-3y - 17) - 0.5y = 6.1

 -0.9y - 5.1 - 0.5y = 6.1

-1.4y - 5.1 = 6.1

-1.4y = 5.1 + 6.1

-1.4y = 11.2

     y = 11.2/-1.4

     y = -8

     Substitute y into the first  equation and solve for x

               x = -3y - 17

                x = -3(-8) - 17

                x = 24 - 17

                x = 7
