Answer:

slope = 1

y intercept = (0,8)

Step-by-step explanation:

the equation y = x + 8 is put in y = mx + b form

where m = slope and b = y intercept

in the equation y = x + 8 , the value of "m" is 1 meaning the slope is 1 and the value of "b" is 8 so the y intercept is (0,8)

Answer:

m = 1 and b = 8

Step-by-step explanation:

y = x + 8

Here the slope is 1, since y = mx+ b. m is the slope so m = 1. b is the

y-intercept so b=8

The principal in this scenario is $ 8000.

Simple Interest can be defined as the sum paid back for using the borrowed money, over a fixed period of time.

Compound Interest can be defined as when the sum principal amount exceeds the due date for payment along with the rate of interest, for a period of time.

It is Given that:

Priscilla invested 20,000 that means the total amount she invested.

Amount= $ 20,000

Rate of interest=12%

Time= 5 year

Interest= $12,000.

By the formula;

Amount =  principal + Interest

Principal = Amount - Interest

Principal= $ 20,000- $12,000

Principal=$ 8000

Hence, the principal in this scenario is $ 8000.

Maggie (study time) - Julie (study time)

Substitute values into the expression

2/5 - 1/4

Find the denominators' Least Common Multiple (LCM)

First five multiples of 5: 5, 10, 15, 20, 25

First five multiples of 4: 4, 8, 12, 16, 20

Since [20] is the first term that appears in both multiples, it would be the LCM of 4 and 5

Convert the fractions to common denominator

2/5 = (2 × 4) / (5 × 4) = 8 / 20

To find the answer, calculate the area of the rectangles.

Area of rectangle = Length * Width

Rectangle A                                   Rectangle B                         Rectangle C

= 6 * 3                                              = 9 * 9                                  = 5 * 4

= 18 cm²                                           = 81 cm²                              = 20cm²

Rectangle D                                  Rectangle E

= 9 * 2                                              = 7 * 2

Let's say you had a cake that is cut into 5 equal slices. Then someone eats 2 of those slices. They ate 2/5 of the cake.

Now let's say you have another cake that you cut into 10 equal slices. If someone eats 4 of those ten, then they have eaten 4/10 = 2/5 of the cake.

Check out the diagram below to see a visual of how 4/10 and 2/5 are equivalent fractions.

Going from 2/5 to 4/10 has us multiply top and bottom by 2.

-----------

Similarly, 1/2 = 5/10 after multiplying top and bottom by 10

The original expression 2/5 + 1/2 turns into 4/10 + 5/10

Then you add the numerators to get 4+5 = 9, placing that over the common denominator of 10

Answer:

Where is the question?

Answer:

Step-by-step explanation:

El recíproco de un número es el inverso multiplicativo del número, lo que significa que el producto de un número y su recíproco es igual a 1.

Para encontrar el recíproco de 43/5, primero debemos escribir el número como una fracción. Luego, intercambiamos el numerador y el denominador para obtener el recíproco.

El recíproco de 43/5 es entonces:

Recíproco de 43/5 = 5/43

Esto se puede verificar multiplicando 43/5 y 5/43:

(43/5) * (5/43) = 1

Por lo tanto, el recíproco de 43/5 es 5/43.

Answer:

\(\frac{5}{43}\)

Step-by-step explanation:

Reciprocal just means turn the fraction upside down.

First subtract the difference between the two:

200 - 50 = 150

Now divide that by 2:

150/2 = 75

Bills share is $75

Now add the $50 to 75 to get Ann's share:

75 + 50 = $125

Ann's share is $125

Bill's share is $75

The linear function with a x-intercept at x = 3 and a y-intercept at y = 6 is:

y = -2x + 6.

The slope-intercept representation of a linear function is given by the equation presented as follows:

y = mx + b

The coefficients of the function and their meaning are described as follows:

The line has an y-intercept of y = 6, hence the parameter b is given as follows:

b = 6.

When x = 3, y = 0, meaning that when x increases by 3, y decays by 6, hence the slope m is given as follows:

m = -6/3

m = -2.

Hence the function is defined as follows:

y = -2x + 6.

The problem asks for a linear function with a x-intercept at x = 3 and a y-intercept at y = 6.

Answer:

\(f(n) = f(n- 1) * 2\); \(f(1) = 3\)

Step-by-step explanation:

Given

\(1\ minute = 3\ friends\)

Every other minute

\(Each\ friend = 2\ other\ friends\)

Required

Determine the recursive function

Let the number of minutes be represented with n.

The initial condition can be represented as:

\(n = 1\)

\(f(1) = 3\) --- i.e. 3 friends initially at the first minute

At every other minutes:

\(n \ge 2\) i.e 2 minutes upwards

This means that n follows the following sequence

\(n \to n, n -1, n -2,n -3, n - 4,.....,4,3,2\)

Note that the difference between each term is 1.

This means that recursive function has to be defined backwards i.e.

\(f(n) = f(n- 1) * k\)

Where k = 2

i.e. The number of friends that received the video from each friend

So, we have:

\(f(n) = f(n- 1) * 2\)

Hence, the recursive function is:

\(f(n) = f(n- 1) * 2\); \(f(1) = 3\)

The Area of the shaded portion is: 72 square inches

The formula for the area of a triangle is given by the formula:

Area = ¹/₂ * base * height

Now, to get the area of the shaded portion, we will get the area of the larger triangle and subtract the area of the smaller one from it.

Thus:

Area of larger triangle = ¹/₂ *  17 * 13 = 110.5 square inches

Area of smaller triangle =  ¹/₂ * 11 * 7 = 38.5 square inches

Thus:

Area of shaded portion = 110.5 square inches - 38.5 square inches

Area of shaded portion = 72 square inches

Answer:

(-0.481 , -0.144)

Step-by-step explanation:

Confidence Interval for difference is proportion formula is given as:

p1 - p2 ± z ×√[p1(1 - p1)/n1 +p2 (1 - p2)/n2]

For p1

Of the 96 people surveyed in the eastern half of a country, 42 said they fly to visit family members for the winter holidays.

n1 = 96 people

p1 = x/n

x = 42 people

p1 = 42/96

= 0.4375

1 - p1 = 0.5625

For p2

Of the 108 people surveyed in the western half of the country, 81 said they fly to visit family members for the winter holidays.

n2 = 108 people

p2 = x/n

x = 81 people

p2 = 81/108

= 0.75

1 - p2 = 0.25

99% confidence interval = 2.576

p1 - p2 ± z ×√[p1(1 - p1)/n1 +p2 (1 - p2)/n2]

= 0.4375 - 0.75 ± 2.576 ×√[0.4375(1 -0.4375)/96 +0.75 (1 - 0.75)/108]

= -0.3125 ± 2.576 × √0.4375× 0.5625/96 + 0.75 × 0.25 /108

= -0.3125 ± 2.576 × √0.0025634766 + 0.0017361111

= -0.3125 ± 2.576 × √0.0042995877

= -0.3125 ±2.576 × 0.0655712414

= -0.3125 ± 0.1689115178464

Confidence Interval

-0.3125 - 0.1689115178464

= -0.4814115178

Approximately to 3 decimal places = -0.481

= -0.3125 + 0.1689115178464

= -0.1435884822

Approximately to 3 decimal places = -0.144

Therefore, the 99% confidence interval for difference in proportion = (-0.481 , -0.144)

To find the number of temperatures in the set, we can divide the sum of the temperatures by the mean temperature.

Number of temperatures = Sum of temperatures / Mean temperature

In this case, the sum of temperatures is given as 2,516 and the mean temperature is given as 74 degrees Fahrenheit.

Number of temperatures = 2,516 / 74

Calculating the division:

Number of temperatures ≈ 34.05

Since we cannot have a fraction of a temperature, we need to round the result to the nearest whole number. Therefore, there are approximately 34 temperatures in the set.
