According to komonews.com, the chances it will rain on any day in the 1st week of January in Seattle is about 0.614.

a) What is the probability that it will rain on January 1st?

b) What is the probability that it will rain for the first time in the New Year on January 3rd?

c) What is the probability that the people of Seattle get to wait at least 3 days until it rains for the first time in the New Year?

d) How many days, on average, do they wait for the first day of rain in the New Year?

e) If X = the number of days until it rains for the first time, is X binomial or geometric or neither? Explain.

Answers

(a) The probability of rain on January 1st is 0.614. (b) The probability of rain for the first time in the New Year on January 3rd is 0.136*0.614 = 0.083. (c) the probability that people of Seattle get to wait at least 3 days until it rains for the first time in the New Year is 0.053. (d) They wait for the first day of rain in the New Year is 1/0.614 ≈ 1.63 days. (e) The distribution of X is a geometric distribution.

a) The probability that it will rain on January 1st can be estimated using the information provided by komonews.com, which states that the chances of rain on any day in the first week of January in Seattle is about 0.614. Assuming that the probability of rain is constant across all days of the week, the probability of rain on January 1st is also 0.614.

b) The probability that it will rain for the first time in the New Year on January 3rd can be calculated by considering the probability of no rain for the first two days, followed by rain on the third day. The probability of no rain for the first two days is [tex](1-0.614)^2[/tex] = 0.136, and the probability of rain on the third day is 0.614. Therefore, the probability of rain for the first time in the New Year on January 3rd is 0.136*0.614 = 0.083.

c) The probability that the people of Seattle get to wait at least 3 days until it rains for the first time in the New Year can be calculated by considering the probability of no rain for the first three days. The probability of no rain for the first three days is [tex](1-0.614)^3[/tex] = 0.053. Therefore, the probability that people of Seattle get to wait at least 3 days until it rains for the first time in the New Year is 0.053.

d) The expected value or average of the number of days people in Seattle wait for the first day of rain in the New Year can be calculated by using the formula E(X) = 1/p, where p is the probability of rain on any given day. Therefore, the expected value or average number of days people in Seattle wait for the first day of rain in the New Year is 1/0.614 ≈ 1.63 days.

e) The number of days until it rains for the first time in the New Year, X, is a geometric random variable since it represents the number of trials until the first success (rain). The probability of success (rain) remains constant over time, and the trials (days) are independent of each other. Therefore, the distribution of X is a geometric distribution.

Solve the following system of equations by linear combination:


3x – y = 7

x + y = 5

Answers

Answer:

x=3, y=2

Step-by-step explanation:

First Add both equations

3x-y=7                     ---1

x+y=5                      ---2

----------

so we get, 4x=12

so x=3

Now plug x back into equation 2 so we get y=2

Step-by-step explanation:

that means we optionally multiply one or both equations with some factors, so that one variable term has the same coefficient in both equations but with different signs.

and then we add both equations giving us one equation in the other variable, which we can solve.

and then we use that with any of the original equations to solve for the first variable.

in this case we don't need the multiplication step, as the terms in y have already the same coefficient (1) with different signs.

so, we add both equations

3x - y = 7

+ x + y = 5

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

4x 0 = 12

4x = 12

x = 12/4 = 3

x + y = 5

3 + y = 5

y = 5 - 3 = 2

The daily high temperatures, in degrees Fahrenheit, of Des Moines for one week were: Day Temperature (in Fahrenheit) Monday 64.5 Tuesday 64 Wednesday 66.5 Thursday 64 Friday 62.5 Saturday 61 Sunday 63 Using the data above, what is the standard error of the sample mean? Answer choices are rounded to the hundredths place.

Answers

Answer:0.65

Step-by-step explanation:

The standard error of the sample mean is approximately 0.682, rounded to the hundredths place.

To calculate the standard error of the sample mean, we need to find the sample mean and the standard deviation of the data. Then we can divide the standard deviation by the square root of the sample size.

First, let's calculate the sample mean:

Mean = (64.5 + 64 + 66.5 + 64 + 62.5 + 61 + 63) / 7 = 64.14

Next, let's calculate the standard deviation. We will use the sample formula for standard deviation (Bessel's correction):

Calculate the squared differences from the mean for each temperature:

(64.5 - 64.14)² = 0.1904

(64 - 64.14)² = 0.0204

(66.5 - 64.14)² = 5.5376

(64 - 64.14)² = 0.0204

(62.5 - 64.14)² = 2.6836

(61 - 64.14)² = 9.8324

(63 - 64.14)² = 1.2696

Calculate the sum of the squared differences:

Sum = 0.1904 + 0.0204 + 5.5376 + 0.0204 + 2.6836 + 9.8324 + 1.2696 = 19.5544

Calculate the variance:

Variance = Sum / (n - 1) = 19.5544 / (7 - 1) = 3.25907

Calculate the standard deviation:

Standard Deviation = sqrt(Variance) = sqrt(3.25907) = 1.80597

Finally, let's calculate the standard error of the sample mean:

Standard Error = Standard Deviation / sqrt(n) = 1.80597 / sqrt(7) ≈ 0.682

Therefore, the standard error of the sample mean is approximately 0.682, rounded to the hundredths place.

cart a with mass m travels in the x direction with a speed of 4 m/s. it collides with car t b, which has mass 3m and is initially at rest. after the collision, cart a moves in the -x direction and cart b moves in the x direction. assume that the collision was perfectly elastic

Answers

After the collision, cart a moves in the negative x direction with a speed of 4 m/s, and cart b moves in the positive x direction with a speed of 2 m/s.

In a perfectly elastic collision, the total momentum of the system is conserved, as well as the total kinetic energy. This means that the sum of the momenta of the carts before the collision is equal to the sum of the momenta after the collision. In this case, since cart b is initially at rest, its initial momentum is zero.

We can use conservation of momentum to determine the final velocities of the carts. Let the velocity of cart b after the collision be v, then the velocity of cart a after the collision is -4 m/s. The momentum of cart a before the collision is m(4 m/s) = 4m, and the momentum of cart b after the collision is 3mv.

Using conservation of momentum, we have:

m(4 m/s) + 0 = m(-4 m/s) + 3mv

Simplifying this equation, we get:

8m = 3mv + 4m

Dividing both sides by 3m, we get:

v = (8/3) - (4/3)v

Solving for v, we get:

v = 2 m/s

So after the collision, cart a moves in the negative x direction with a speed of 4 m/s, and cart b moves in the positive x direction with a speed of 2 m/s. We can verify that this satisfies conservation of momentum:

m(4 m/s) + 0 = m(-4 m/s) + 3m(2 m/s)

4m = 4m

This result shows that in a perfectly elastic collision, even though the carts exchange momentum, the total momentum of the system is conserved.

A family has two cars. During one particular week, the first car consumed 25 gallons of gas and the second consumed 20 gallons of gas. The two cars drove a
combined total of 1075 miles, and the sum of their fuel efficiencies was 50 miles per gallon. What were the fuel efficiencies of each of the cars that week?
First car: miles per gallon
Second car: miles per gallon

Answers

We can conclude after answering the presented question that As a equation result, the first car's fuel efficiency was 15 miles per gallon, whereas the second car's fuel economy was 35 miles per gallon.

What is equation?

An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x + 3" equals the number "9". The purpose of equation solving is to determine the value or readings of the variable(s) that will allow the equation to be true. Equations can be simple or complicated, regular or nonlinear, and include one or more elements. In the calculation "x2 + 2x - 3 = 0," for example, the variable x is raised to the second power. Lines are utilised in many different areas of mathematics, such as algebra, calculus, and geometry.

Let's name the first car's fuel efficiency (miles per gallon) x and the second car's fuel efficiency y. We are aware of the following:

The first automobile used 25 gallons of gas and covered 25 miles.

The second automobile used 20 gallons of petrol and drove 20 miles.

The two automobiles went a total of 1075 miles, thus 25x + 20y = 1075.

Their combined fuel economy was 50 miles per gallon, thus x + y = 50/1 = 50.

[tex]25x + 20y = 1075\\x + y = 50\\25x + 20y = 1075\\-20x - 20y = -1000\\5x = 75x = 15\\x + y = 50\\15 + y = 50\\y = 35\\[/tex]

The equation 24b = t is used to find b, the cost of 1 bottle of water when sold in a 24‐pack case with a case price of t dollars. What is the cost of 1 bottle of water when the case price is $7.50?

Answers

The cost of 1 bottle of water when sold in a 24-pack case with a case price of $7.50 is $0.3125 or 31.25 cents.

The given equation is 24b = t, where b is the cost of one bottle of water and t is the price of a case of 24 bottles.

We are given that the price of the case is $7.50. Substituting this value in the equation, we get:

24b = 7.50

To solve for b, we need to isolate it on one side of the equation. We can do this by dividing both sides by 24:

b = 7.50/24

Simplifying this expression, we get:

b = 0.3125

Therefore, the cost of 1 bottle of water when sold in a 24-pack case with a case price of $7.50 is $0.3125 or 31.25 cents. In other words, if you were to buy a case of 24 bottles of water for $7.50, each bottle of water would cost you about 31.25 cents.

Food: $1400 - $240 = $1160

The remaining 20% of the sum given in April was spent on cleaning services, which means:

Cleaning services: 20% of sum given in April = 0.2 x $x (where x is the sum given in April)

We can set up an equation based on the above information:

$200 + $1160 + 0.2x = x

Simplifying and solving for "x":

$1360 + 0.2x = x

0.8x = $1360

x = $1700

Therefore, the sum given to the kindergarten in April was $1700, which means it was reduced by:

($2000 - $1700) / $2000 x 100% = 15%

So, the sum given to the kindergarten was reduced by 15%.

A die is rolled 2 times. What is the probability of getting a 1 on the first roll and a 2 on the second roll.

Answers

The probability of getting a '1' on the first roll and '2' on the second roll for the given expression is [tex]\frac{1}{18}[/tex] .

What about probability?

In mathematics and statistics, probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 indicates an impossible event and 1 indicates a certain event.

The probability of an event A is denoted by P(A) and is defined as the ratio of the number of favorable outcomes to the total number of possible outcomes. In other words, it is the number of ways that event A can occur divided by the total number of possible outcomes.

For example, if you roll a fair six-sided die, the probability of rolling a 4 is 1/6, since there is only one favorable outcome (rolling a 4) out of six possible outcomes (rolling a 1, 2, 3, 4, 5, or 6).

Probability is used in many different fields, such as gambling, statistics, and science, to make predictions about the likelihood of different outcomes. It is also used to model complex systems and to test hypotheses in scientific experiments.

According to the given information:

When a die is rolled 2 times, the output we get

(1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6)

(2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6)

(3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6)

(4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)

(5, 1) (5, 2) (5, 3) (5, 4) (5, 5) (5, 6)

(6, 1) (6, 2) (6, 3) (6, 4) (6, 5) (6, 6)

Total no of getting '1' on first roll and '2' on second roll = 2

Total outcomes = 36

⇒ [tex]\frac{2}{36}[/tex]

The equation of the tangent line is y = -x/3 + 1/3 where

m = -1/3 and b = 1/3

What is the equation of a tangent line to a curve?

The equation of a tangent line to a curve is the equation of the line that touches the curve at that point and tangent to it.

To find the equation of the tangent line to the curve y = 1/(3sinx + 3cosx) at (0, 1/3), we know that the value of the tangent at that point is the derivative of the curve at that point.

so, differentiating y wiith respect to x, we have

y =  1/(3sinx + 3cosx)

= (3sinx + 3cosx)⁻¹

Let u = 3sinx + 3cosx

y = u⁻¹

dy/dx = du⁻¹/du du/dx

= -u⁻² du/dx

Now du/dx = d(3sinx + 3cosx)/dx

= d3sinx/dx + d3cosx/dx

= 3cosx - 3sinx

So, dy/dx = -u⁻² du/dx

= -(3sinx + 3cosx)⁻²(3cosx - 3sinx)

= -(3cosx - 3sinx)/3sinx + 3cosx)²

Now, at (0, 1/3)

dy/dx = -(3cosx - 3sinx)/3sinx + 3cosx)²

= -(3cos0 - 3sin0)/3sin0 + 3cos0)²

= -[3(1) - 3(0)]/[3(0) + 3(1))²

= -[3 - 0]/[0 + 3)²

= -3/3²

= -1/3

Now, the equation of a line in slope form passing through the point (x', y') is

(y - y')/(x - x') = m where m = slope

For the tangent line

m = dy/dx = -1/3, x = 0 and y = 1/3

So, substituting the values of the variables into the equation we have

(y - y')/(x - x') = m

(y - 1/3)/(x - 0) = -1/3

(y - 1/3)/x = -1/3

y - 1/3 = -x/3

y = -x/3 + 1/3

Comparing this with the equation of a line in slope-intercept form y = mx + b where m = slope and b = y-intercept

m = -1/3 and b = 1/3

So, the equation of the tangent line is y = -x/3 + 1/3 where

m = -1/3 and b = 1/3

1. The distance around Heather's bedroom is 44 feet.
The width of the room is 10 feet, what is the length of the room?

Answers

To find the length of Heather's bedroom, we can use the formula for the perimeter of a rectangle, which is P = 2L + 2W, where P is the perimeter, L is the length, and W is the width.

We have the perimeter (P = 44 feet) and the width (W = 10 feet). Plugging these values into the formula:

44 = 2L + 2(10)

44 = 2L + 20

Now, we can solve for the length (L):

Subtract 20 from both sides of the equation:

24 = 2L

Divide by 2:

L = 12 feet

So, the length of Heather's bedroom is 12 feet.

Answer: x=43

Step-by-step explanation:

We know The interior angles in a hexagon sum to 720°.


so we can add all the angles and equal them to 720


100 + 4x + (3x + 3) + (5x-2) + 103 = 720

Simplify by combining like terms

(100 + 3 -2 + 103) and (4x + 3x +5x)

204 + 12x = 720

Subtract 204 from both sides to isolate x


204 - 204 + 12x = 720 - 204

12x = 516

Divide both sides by 12 to solve for x


12/12 x = 516/12

Simplify


x = 43

to check your work, substitute the value of x into your equation and solve


100 + 4x + 3x + 3 + 5x-2 + 103 = 720

100 + 4(43) + (3)(43) + 3 + (5)(43) -2 + 103 = 720

100 + 172 + 129 + 3 + 215 -2 + 103 = 720

720 = 720

They equal so your solution is correct
