I think its 1.012(500 - 100) = 400* 1.012 = 404.80 dollars

Hi there:)

Since the interest rate is 0.012 per month
So the interest charge
500×0.012=6
The ending balance is
500+6−100=406

Hope it helps

Circle X with a radius of 6 units and circle Y with a radius
asambeis [7]

Answer:

Option C.

Step-by-step explanation:

It is given that radius of circle X is 6 units and radius of circle Y is 2 units.

Here, circle Y is smaller and circle X is larger.

\text{Scale factor}=\dfrac{\text{Radius of circle X}}{\text{Radius of circle Y}}

\text{Scale factor}=\dfrac{6}{2}

\text{Scale factor}=3

If we translate the circles so they share a common center point, and after that we dilate circle Y by a scale factor of 3, then we get circle which is equal to circle X.

We know that, after dilation the figure and its image are similar.

Hence, we can say that both circles are similar.

Therefore, the correct option is C.

Answer:

Conversion a mixed number -3 1

2

to a improper fraction: -3 1/2 = -3 1

2

= -3 · 2 + (-1)

2

= -6 + (-1)

2

= -7

2

To find new numerator:

a) Multiply the whole number -3 by the denominator 2. Whole number -3 equally -3 * 2

2

= -6

2

b) Add the answer from previous step -6 to the numerator 1. New numerator is -6 + 1 = -5

c) Write previous answer (new numerator -5) over the denominator 2.

Minus three and one half is minus five halfs

Conversion a mixed number -1 1

4

to a improper fraction: -1 1/4 = -1 1

4

= -1 · 4 + (-1)

4

= -4 + (-1)

4

= -5

4

To find new numerator:

a) Multiply the whole number -1 by the denominator 4. Whole number -1 equally -1 * 4

4

= -4

4

b) Add the answer from previous step -4 to the numerator 1. New numerator is -4 + 1 = -3

c) Write previous answer (new numerator -3) over the denominator 4.

Minus one and one quarter is minus three quarters

Multiple: -7

2

* (-5

4

) = -7 · (-5)

2 · 4

= 35

8

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(35, 8) = 1. In the next intermediate step the fraction result cannot be further simplified by cancelling.

In words - minus seven halfs multiplied by minus five quarters = thirty-five eighths.

Unary minus: -7

2

= -7

2

Subtract: the result of step No. 4 - (-17

4

) = -7

2

- (-17

4

) = -7 · 2

2 · 2

- (-17)

4

= -14

4

- (-17

4

) = -14 - (-17)

4

= 3

4

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 4) = 4. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 4 = 8. In the next intermediate step the fraction result cannot be further simplified by cancelling.

In words - minus seven halfs minus minus seventeen quarters = three quarters.

Compare: the result of step No. 3 = the result of step No. 5 = 35

8

= 3

4

= 35

8

vs 3

4

= 35

8

vs 3 · 2

4 · 2

= 35

8

vs 6

8

= 35 vs 6 = No

Vika [28.1K]

Answer:

significance level

Step-by-step explanation:

In other to determine whether her sample proportion is "different enough" than the claimed population proportion, We will set significance level because p-value should be compared to significance level that will allow Joanna to make a conclusion about whether her sample proportion is "different enough" than the claimed population proportion.
