Shawn has a bank account with $3,069. He decides to invest the money at 3.25% interest, compounded annually. How much will the investment be worth after 5 years? Round to the nearest dollar.

Answers

The value of his investment at the third year is
F (3)=300×(1.02)^(3)=318.36

The value of his investment at the fifth year is
F (5)=300×(1.02)^(5)=331.22

The average rate of change of the value is
(331.22−318.36)÷2 years=6.43 per year

The investment worth after 5 years to the nearest dollar will be $3601.

What is compound interest?

We know that the compound interest is given as

A = P(1 + r)ⁿ

Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.

Shawn has a bank account with $3,069. He decides to invest the money at 3.25% interest, compounded annually.

The worth of investment after 5 years is calculated as,

A = $3,069 x (1 + 0.0325)⁵

A = $3,069 x 1.0325⁵

A = $3,069 x 1.1734

A = $3601

The investment worth after 5 years to the nearest dollar will be $3601.

Seventy percent of kids who visit a doctor have a fever, and 30% of kids with a fever have sore throats. What’s the probability that a kid who goes to the doctor has a fever and a sore throat?

Answers

Answer:

0.21

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

Probability that a kid who goes to the doctor has a fever and a sore throat = probability a child would have fever x probability a child would have a sore throat

0.7 x 0.3 = 0.21

Step-by-step explanation:

Given

The attached graph

Required

The graph equation

Pick two points from the graph, we have:

[tex](m_1,c_1) = (0,15)[/tex]

[tex](m_2,c_2) = (40,25)[/tex]

Start by calculating the slope (a)

[tex]a = \frac{c_2 - c_1}{m_2 - m_1}[/tex]

So, we have:

[tex]a = \frac{25 - 15}{40 - 0}[/tex]

[tex]a = \frac{10}{40}[/tex]

[tex]a = \frac{1}{4}[/tex]

The equation is then calculated using:

[tex]c = a(m - m_1) + c_1[/tex]

So, we have:

[tex]c = \frac{1}{4}(m - 0) + 15[/tex]

[tex]c = \frac{1}{4}m+ 15[/tex]

Answer:

GX = 122°XU = 148°UG = 90°

Step-by-step explanation:

Each arc has the same measure as its central angle. The sum of all of them is 360°.

  angle UOG is marked as a 90° angle, so arc UG is 90°.

  angle GOX is marked as 122°, so arc GX is 122°.

  angle XOU fills out the rest of 360°, so its measure is 360° -90° -122° = 148°. That means are XU is 148°.

The arc measures are ...

GX = 122°XU = 148°UG = 90°

What is a coordinate system?

'A coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points.'

According to the given problem,

Coordinates of G before translation = ( 2 , -4 )

After translation of 1 unit to the right, the value of x will become 3.

Coordinates after translation of 1 unit to the right = ( 3 , -4 )

After translation of 5 units down, the value of y will become -9.

Coordinates after translation of 5 units down ( G' ) = ( 3 , -9 )

Hence, we can conclude, the coordinates of G' is ( 3 , -9 ).

Hyp = 9.42

R = 71º

S = 19º

Step-by-step explanation:

Use the Pythagorean Theorem

a² + b² = c²

c² = 8.9² + 3.1²

c² = 79.21 + 9.61

c² = 88.82

Take the square root of both sides

c = 9.4244363227

Rounded

Hyp = 9.42

--------------------

sin  = opp/hyp

sinR = 8.9 / 9.42

R = arcsin(8.9/9.42)

Answers

Answer:

The probability that a person adds both sugar and honey is 0.04.

Step-by-step explanation:

P(H) means "probability that a random person adds honey"

P(S) means "probability that a random person adds sugar"

P(H or S) means "probability that a random person adds AT LEAST ONE OUT OF honey and sugar"

P(H and S) means "probability that a random person adds BOTH honey and sugar"

We can simplify it as "percentage of people who add" instead of "probability that a random person adds", and then it should be clear to us that

P(H or S) = P(H) + P(S) - P(H and S)

The equation comes from the face that if we want to compute percentage of people who add at least one sweetener, we can sum people who add honey and people who add sugar, but we would have counted people who use both TWICE, so we can correct by subtracting. As follows:

P(H and S) = P(H) + P(S) - P(H or S)

P(H and S) = 0.15 + 0.68 - 0.79 = 0.83 - 0.79 = 0.04

So the probability that a person adds both sugar and honey is 0.04.
