Answer:

5.6

Step-by-step explanation:

Sheryl got the following scores on her spelling tests.

95, 89, 99, 85, 82

Mean = sum of all observations/ Number of observations

Sum of all observations [tex]=95+89+99+85+82=450[/tex]

Number of observations = 5

So,

Mean [tex]=\frac{450}{5}=90[/tex]

Let M denotes the mean

Mean absolute deviation [tex]=\frac{\sum_{i=1}^{n}\left | x_i-M \right |}{n}[/tex]

Put [tex]n=5[/tex]

So,

Mean absolute deviation [tex]=\frac{\sum_{i=1}^{5}\left | x_i-M \right |}{5}=\frac{|95-90|+|89-90|+|99-90|+|85-90|+|82-90|}{5}=\frac{5+1+9+5+8}{5} =\frac{28}{5}=5.6[/tex]

Answer:

a) the domain is the set of all real numbers

Step-by-step explanation:

Given:

An exponential function and its graph.

A line parallel to [tex]x[/tex] axis is drawn at [tex]y=-9[/tex] which is a dashed line.

Dashed line means, the function does not attain a value equal to [tex]y=-9[/tex].

Domain of a function, [tex]y=f(x)[/tex] is the set of values which can be possible for the variable [tex]x[/tex] that can be given as input.

Range of a function, [tex]y=f(x)[/tex] is the set of possible values of [tex]y[/tex] i.e. the output of the function.

As seen from the graph, the domain of the exponential function does not have any constraint on it.

Therefore, any real number can be given as input.

So, a) The domain is the set of all real numbers.

Let us discuss about the range of function.

As stated above as well, the range of the function can not contain the value [tex]y=-9[/tex].

And there is no value possible below it.

So, the range is all real numbers greater than -9.

The answer is:

"a) the domain is the set of all real numbers"  is true.

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the

10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:

x = 0

Step-by-step explanation:

First, distribute the -2 to the parentheses:

-14 - 8x = -2(-3x + 7)

-14 - 8x = 6x - 14

Add 14 to both sides:

-8x = 6x

Subtract 6x from both sides:

-14x = 0

Divide each side by -14:

x = 0

So, x = 0

Answer:

0

Step-by-step explanation:

-14-8x=6x-14(cancel equal terms)

-8x=6x(move the variable to the left)

-8x-6x=0(collect like terms)

-14x=0Divide both sides)

x=0

Answer:

y = 53

Step-by-step explanation:

To get the answer, first put 19 in place of the x, and then times that iwth two, getting 38, you add that to 15. The answer is 53.

Answer:The Value of the coin after 19 years is $53.

Step-by-step explanation:If x=age, then simply substitute the x in “2x+15” for 19.After you do that you should get y=2(19)+15.Do the math to get y=38+15. Y=53.

Answer:

133

Step-by-step explanation:

56/4=14 and 70/5=14. 14 x 9 = 126

30 mins is half of an hour which means you need to divide 14 by 2 which gives you 7.

126 + 7 = 133

133 parts the machine can make in 9 hours, 30 minutes.

Two or more expressions with an Equal sign is called as Equation.

A machine can make 56 parts in 4 hours.

56=4x

A machine can also make 70 parts in 5 hours.

70=5x

Now we need to write an equation that relates the number of parts

the machine can make and the time in hours.

14=x

Now, we need to find parts the machine can make in 9 hours, 30 minutes.

14 x 9 = 126

As 30 minutes is half an hour, so divide 14 by 2 we get 7

126 + 7 = 133

Hence 133 parts the machine can make in 9 hours, 30 minutes.

Answer:

5/6

Step-by-step explanation:

7/9 and 5/6 can have the same denominator of 54. Now, you can look only at the numerators, 42 and 45. 45 is greater, so 5/6 is greater than 7/9

5/6 is greater than 7/9

A common fraction is a numeral which represents a rational number. For example 2/3

Given here, 7/9 and  5/6 now 7/9 = 0.777 and 5/6= 0.833

Thus clearly 5/6 >7/9

Hence, 5/6 is greater than 7/9

Answer: z = -6

Step-by-step explanation:

Hi there! I will be showing you how to solve the given equation. If you have any questions feel free to comment it down below.

Step 1: Remove parentheses.

-5z - 12 = 18

Step 2: Add 12 to both sides.

-5z = 18 + 12

Step 3: Simplify 18 + 12 to 30.

-5z = 30

Step 4: Divide both sides by -5.

z = [tex]-\frac{30}{5}[/tex]

Step 5: Simplify [tex]\frac{30}{5}[/tex] to 6.

z = -6
