Answer:

Step-by-step explanation:

Domain

The domain is the horizontal extent of the graph. Here, there are arrows at the ends of the curve, pointing both directions. We understand that to mean the graph extends to infinity in both directions. Then the domain is "all real numbers".

  -∞ < x < ∞

  (-∞, ∞)

Range

The range is the vertical extent of the graph. Here the graph extends from a low of 5 °F to a high of 35 °F. The arrows at the end of the graph do not indicate that the portion not shown will have any different range. Hence the range is ...

 5 ≤ y ≤ 35

Answer:

We Do not have enough evidence

Step-by-step explanation:

H0 : σ² ≤ 1.1

H0 : σ² > 1.1

The test statistic (X²) :

χ² = [(n - 1) × s²] ÷ σ²

n = sample size, = 20

s² = 1.6

σ² = 1.1

α = 0.01

χ² = (19 * 1.6) / 1.1

χ² = 27.64

Pvalue :

Using the Pvalue from Chisquare score calculator ; χ² = 27.64 ; df = 19

Pvalue = 0.091

If Pvalue < α ; Reject H0

0.091 > 0.01

Hence, Pvalue > α ; Thus we fail to reject H0.

We thus conclude that, we do not have enough evidence to support the claim that her standard deviation is greater than the target.

The interest rate of the savings account would be = 33.3%

To calculate the interest rate of the savings account, the formula for simple interest should be used. That is;

Simple interest = Principal × time × Rate/100

simple interest = 1250-312.50 = 937.5

Principal amount = $312.50

Time = 9 years

rate = ?

That is;

937.5 = 312.50 × 9 × R/100

make R the subject of formula:

R = 937.5× 100/312.50 × 9

= 93750/2812.5

= 33.3%

Just factor out the 3:

The area under the graph using the first two and then four rectangles = 0.221 unit square

According to the graphs given in the below figure,

Given in the question,

f(x) = \(x^{3}\) when x = 0 and x = 1

The first rectangle of the first graph goes from 0 to 0 .6,

Width = 0.6

Height measured from the middle point = 0.3

f( 0.3) = \(( 0.3)^{3}\)

f(0.3) = 0.027 units.

Area of first rectangle = 0.6 x 0.027 = 0.0162 unit square

Now taking the second rectangle of the first part,

It is going from 0.6 to 1.0,

Width = 0.4 units

height = 0.8 units

Height measured from the middle-

f(0.8) = \((0.8)^{3}\) = 0.512

Area of the second part of the rectangle = 0.512 x 0.4

= 0.2048 unit square

Final area = 0.2048 + 0.0162 = 0.221 square units

Therefore, the same could be done with the second part rectangle of 4

For the given first part of four rectangles = width = 0.6 units and height = 0.1 unit

so f(0.1) = \(0.1^{3}\)

= 0.001 units

Therefore, the area under the graph using the first two and then four rectangles = 0.221 unit square

The function f(x) = -2(4)ˣ⁺¹ +140 represents the number of tokens a child has x hours after arriving at an arcade. The practical domain and range of the function are x ≥ 0 and The practical range of the situation is [140, ∞).

The given function is f(x) = -2(4)ˣ⁺¹+ 140, which represents the number of tokens a child has x hours after arriving at an arcade.

To determine the practical domain and range of the function, we need to consider the constraints and limitations of the situation.

For the practical domain, we need to identify the valid values for x, which in this case represents the number of hours the child has been at the arcade. Since time cannot be negative in this context, the practical domain is x ≥ 0, meaning x is a non-negative number or zero.

Therefore, the practical domain of the situation is x ≥ 0.

For the practical range, we need to determine the possible values for the number of tokens the child can have. Looking at the given function, we can see that the term -2(4)ˣ⁺¹represents a decreasing exponential function as x increases. The constant term +140 is added to shift the graph upward.

Since the exponential term decreases as x increases, the function will have a maximum value at x = 0 and approach negative infinity as x approaches infinity. However, due to the presence of the +140 term, the actual range will be shifted upward by 140 units.

Therefore, the practical range of the situation will be all real numbers greater than or equal to 140. In interval notation, we can express it as [140, ∞).

To summarize:

- The practical domain of the situation is x ≥ 0.

- The practical range of the situation is [140, ∞).

Answer:

B is greater than A by 1/4 of A

Step-by-step explanation:

Let's use the information given in the problem to write expressions for the values of a and b:

a = b - (1/5)b = (4/5)b

b is greater than a by the difference:

b - a = b - (4/5)b = (1/5)b

To express this difference as a fraction of a, we divide by a:

(b - a)/a = ((1/5)b)/((4/5)b) = 1/4

Therefore, b is greater than a by 1/4 of a.

A point, line, or mathematical figure can be converted in one of four ways, and each has an effect on the object's structure and/or position.

Rotation does not change the shape and size of the geometry. But changes the orientation of the geometry.

Step-by-step explanation:

First, you can change the equation to 12 1/2 + 4 1/2, as subtracting a negative number is actually adding it. Then, if easier, the mixed numbers can be changed to improper fractions -- 12 1/2 = 25/2 and 4 1/2 = 9/2. Then add; 25/2 + 9/2 = 34/2, and 34 divided by 2 is 17.

Two years ago, an investment of R1 500000 has increased to R1 700000 and has delivered R40 000 worth of dividends over the two years. Then the return on investment would be 16%.

We can use the following formula to calculate ROI:

ROI = (gain from investment - cost of investment) / cost of investment

where, gain from investment is the total value of the investment (including dividends), and cost of investment is the initial investment.

Using the values given in the question, we can calculate the ROI as:

ROI = ((R1,700,000 + R40,000) - R1,500,000) / R1,500,000 = R240,000 / R1,500,000

ROI = 0.16 or 16%
