Answer:

r < 15.5

Step-by-step explanation:

r - 4.5 < 11

r (- 4.5 + 4.5) < 11 + 4.5

r < 15.5

#1.

For this problem, we can use Pythagorean Theorem (a^2 + b^2 = c^2, where a and b are the legs, and c is the hypotenuse). We are given C, the hypotenuse, and A, a leg of the triangle in this problem.

9^2 + b^2 = 41^2

81 + b^2 = 1681

b^2 = 1600

b = 40 feet

#2.

We will again use Pythagorean Theorem. We are given the height and the length of a leg in this problem.

33^2 + b^2 = 65^2

1089 + b^2 = 4225

b^2 = 3136

b = 56 inches

Answer:

W: (-3,5)

W': (-3,-5)

Y coordinate

Step-by-step explanation:

if you want me to explain it I can in the comments thing

In the plot the coordinates of W is (-3 , 5 ) , and the reflection will be W' (-3 , -5)

A reflection is a transformation representing a flip of a figure. Figures may be reflected in a point, a line, or a plane.

When reflecting a figure in a line or in a point, the image is congruent to the preimage.

A reflection maps every point of a figure to an image across a fixed line.

So in the plot the coordinates of W is (-3 , 5 )

and the reflection will be W' (-3 , -5)

The plot of W and W' is attached with the answer.

Answer:

2 °F

Step-by-step explanation:

Overnight temperature = -7 °F

Total Noon temperature = 9 °F

What was the temperature in Chicago that afternoon?

Temperature in Chicago that afternoon = Total Noon temperature + Overnight temperature

= 9 °F + (-7 °F)

= 9 °F - 7 °F

= 2 °F

Temperature in Chicago that afternoon = 2 °F

Answer:

we reject H0 and conclude that management's belief about variance is untrue.

Step-by-step explanation:

H0 : σ² = 250

H1 : σ² ≠ 250

Sample size, n = 25

xbar = 50.6 ; s² = 500

α = 0.01 ;

The test statistic :

χ² = [(n - 1)s²] ÷ σ²

χ² = [(25 - 1)* 500] ÷ 250

χ² = (24 * 500) / 250

χ² = 12000 / 250

χ² = 48

The critical value:

df = n-1 ; 25 - 1 = 24

χ²(0.01/2 ; 24) = 45.559

Decison :

Reject H0 : if |χ² statistic| > critical value

Since 48 > 45.559

Hemce, we reject H0 and conclude that management's belief about variance is untrue.

854 and 13 x this statment is true

The functions f and g have different axes of symmetry and different intercepts. This statement is true. Therefore, the correct option is option A.

In maths, a quadratic of degree 2 in one or maybe more variables is referred to as a quadratic polynomial. The polynomial function that a quadratic polynomial defines is known as a quadratic function. Prior to the 20th century, the terms "quadratic polynomial" meaning "quadratic function" were practically interchangeable since it was difficult to distinguish between a polynomial and the related polynomial function.

Authors often mean "having degree approximately 2" and other times "having level at most 2" when they refer to a quadratic polynomial. The functions f and g have different axes of symmetry and different intercepts. This statement is true.

Therefore, the correct option is option A.

Answer:

D

Step-by-step explanation:

The right answer is D

I'm sure

The true statement is (d) The graph of g(x) is the graph of f(x) shifted to the right 6 units.

The equation of the function is given as:

[tex]g(x) = f(x -6) = 10^{x-6}[/tex]

The above equation means that, the equation of function f(x) is:

[tex]f(x) = 10^x[/tex]

And the rule of transformation is:

[tex](x,y) \to (x -6,y)[/tex]

This means that:

Function f(x) is shifted right by 6 units to get function g(x)

Hence, the true statement is (d)

Step-by-step explanation:

Answer:

(a) Circle Q is 9.4 units to the center of circle P

(b) Circle Q has a smaller radius

Step-by-step explanation:

Given

[tex]P:(x - 1)^2 + (y + 6)^2 = 9[/tex]

[tex]Q:(x + 4)^2 + (y + 14)^2 = 4[/tex]

Solving (a): The distance between both

The equation of a circle is:

[tex](x - h)^2 + (y - k)^2 = r^2[/tex]

Where

[tex]Center: (h,k)[/tex]

[tex]Radius:r[/tex]

P and Q can be rewritten as:

[tex]P:(x - 1)^2 + (y + 6)^2 = 3^2[/tex]

[tex]Q:(x + 4)^2 + (y + 14)^2 = 2^2[/tex]

So, for P:

[tex]Center = (1,-6)[/tex]

[tex]r = 3[/tex]

For Q:

[tex]Center = (-4,-14)[/tex]

[tex]r = 2[/tex]

The distance between them is:

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2[/tex]

Where:

[tex]Center = (1,-6)[/tex] --- [tex](x_1,y_1)[/tex]

[tex]Center = (-4,-14)[/tex] --- [tex](x_2,y_2)[/tex]

So:

[tex]d = \sqrt{(1 - -4)^2 + (-6 - -14)^2[/tex]

[tex]d = \sqrt{(5)^2 + (8)^2[/tex]

[tex]d = \sqrt{25 + 64[/tex]

[tex]d = \sqrt{89[/tex]

[tex]d = 9.4[/tex]

Solving (b): The radius;

In (a), we have:

[tex]r = 3[/tex] --- circle P

[tex]r = 2[/tex] --- circle Q

By comparison

[tex]2 < 3[/tex]

Hence, circle Q has a smaller radius

Answer:

7 plus threeis equal to same like 10 answer is 10

Answer:

a

Step-by-step explanation:

To obtain f(b) substitute x = b into f(x) , that is

f(b) = 6(b) - 1 = 6b - 1

f(x) and f(b) are very similar. The only difference is that in every place where x is in the function, we now will plug in b. This is just like plugging in a number. For example, if our function was f(x) and we had to plug in 4, it might look something like this: f(4). Very similar, and we know how to plug that number in.

Let's do the same thing with b.

f(x) = 6x - 1

f(b) = 6b - 1

Answer: The actual area of the base of the building is 4900 square feet.

Step-by-step explanation:

We have given, the scale on the model: 1 inch = 35 feet

In model,

Length= 4 feet , Width = 1 inch

As per scale ,

Actual length =  4 x 35 feet

= 140 feet

Actual width = 35 feet

Area of base of the building = Length x width

= 140 x 35

= 4900 square feet

Hence, the actual area of the base of the building is 4900 square feet.

Instructions

This calculator computes the mean absolute deviation from a data set:

You do not need to specify whether the data is for an entire population or from a sample. Just type or paste all observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line. Press the "Submit Data" button to perform the computation. To clear the calculator, press "Reset".

What is the mean absolute deviation

The mean deviation is a measure of dispersion, A measure of by how much the values in the data set are likely to differ from their mean. The absolute value is used to avoid deviations with opposite signs cancelling each other out.

Mean absolute deviation formula

This calculator uses the following formula for calculating the mean absolute deviation:

$ MAD =\frac{1}{n} \sum_{i=1}^n |x_i-\bar{x}|$

where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.
