Step-by-step explanation:
Divide each day by 2
The probability it rains on both days if the probability that it rains in London on any particular day is 0.3 is 0.595
What is the probability?The probability is the likeliness of happening an event. It can be calculated by using the following formula:
Probability=Number of events/Number of total outcomes
How to calculate the probability?
The probability that it rains in London on any particular day is 0.3
If it rains then the probability of it raining the following day decreases to 0.15.
The probability that it rains on the second day=1-0.15=0.85
The probability that it rains on the third day=0.85-0.15=0.7
The probability that it rains on both is=0.85*0.7=0.595
Hence the probability that it rains on both is 0.595

The surface area of the vase is 168.4 square inches.
What is a cylinder?
A cylinder is a three-dimensional geometric shape that has two congruent circular bases connected by a curved surface.
The surface area of the cylindrical vase can be found using the formula SA = B + Ph, where B is the area of the base, P is the perimeter of the base, and h is the height of the vase. Since the vase has a circular base, the area of the base can be found using the formula for the area of a circle: B = πr², where r is the radius of the base.
The diameter of the vase is 4.3 inches, so the radius is half of that, or 2.15 inches. The area of the base is therefore:
B = πr² = 3.14 * (2.15)² ≈ 14.46 square inches.
The perimeter of the base is the circumference of the circle, which can be found using the formula C = 2πr:
P = 2πr = 2 * 3.14 * 2.15 ≈ 13.53 inches.
Now we can use the formula SA = B + Ph to find the surface area of the vase:
SA = B + Ph = 14.46 + 13.53 * 11 ≈ 168.39 square inches.
Rounding to the nearest tenth of a square inch, the surface area of the vase is approximately 168.4 square inches.

b.
x = 28
d.

Answer:
d. x = 7
Step-by-step explanation:
\(\frac{32}{8} = \frac{28}{x}\)
Cross multiply, the denominator "8" is multiplied by numerator "28", while the numerator "32" is multiplied by denominator "x":
8 * 28 = 224
32 * x = 32x
\(32x = 224\)
Divide both sides by 32:

let a be a 3x2 matrix. suppose we know that 3 -5 and -1 1 satisfy the equations and . find a solution to .
The solution matrix x is [-15 15].
Without any additional information, matrix representations of linear mappings allow for explicit computations in linear algebra.
We can use the properties of matrices and vectors to simplify the equation.
First, we know that Au = a and Av = b, so we can substitute these equations into our original equation:
Ax = -5Au + 5Av
Now we can substitute in the values of u and v that we know:
Ax = -5[3 -3] + 5[-5 3]
Which simplifies to:
Ax = [-15 15]
So x = [-15 15] is a solution to the equation Ax = -5a + 5b.

Answer:

Answer:
The team can buy 5 volleyballs at maximum with no money left over.
Step-by-step explanation:
First, you need to find the money that the jerseys used:
12 × 22 = $264
Next, you have to subtract that from the total amount:
350 - 264 = $86
Finally, you have to see how many volleyballs you can buy:
If volleyballs cost $15 each then, 86 ÷ 15 = 5.73333333(Infinite)
But you can not buy part of a volleyball so you would have to buy 5 volleyballs. Then you would only have .7333333(Infinite) money left over, but that wouldn't be good for anything.

After college, you get a job with a starting salary of $37,000. You have a cousin that works at the same company, but he was hired three years before you. Your contract states you will receive a pay raise each year of 6%. Your cousin tells you that his starting salary three years ago was $50,000 and he has been guaranteed a 4% pay raise each year.
1. Make a table showing your salary for your first five years on the job
1. A table showing your salary for the first five years on the job is shown below.
2. Your cousin's salary would be $56243.2 in the year you started working.
3. A formula for your salary is \(P(t) = 37000(1.06)^t\)
A formula for your cousin's salary is \(P(t) = 50000(1.04)^t\)
4. A graph of your salary and your cousin's salary is shown below.
It would take about 16 years before your salary exceed your cousin's salary.
How to write an exponential function to model the situation?In Mathematics and Geometry, an exponential function can be modeled by using this mathematical equation:
\(P(t) = I(1 + r)^t\)
Where:
P(t) represent the future value.t represent the time or number of years.I represent the initial amount.r represent the exponential growth rate.Part 1.
We can create a table of values to model your salary for the first five years on the job as follows;
Years 1 2 3 4 5
Salary ($) 39,220 41,573.2 44,067.6 46,711.7 49,514.4
Part 2.
For your cousin's salary three years after, we have:
y = 50,000(1.04)³
y = $56243.2.
Part 3.
We can write a formula for your salary as follows;
\(P(t) = 37000(1 + 0.06)^t\\\\P(t) = 37000(1.06)^t\)
For your cousin's salary, we have:
\(P(t) = 50000(1 + 0.04)^t\\\\P(t) = 50000(1.04)^t\)
Part 4.
In order to plot a graph of your salary and your cousin's salary, we would use an online graphing tool with a scale of 1 units for 1 year on the x-axis and a scale of 50 units for 1000 dollars on the y-axis.
Since the lines representing both salaries intersect at 15.808, we can logically deduce that it would take approximately 16 years for your salary to exceed your cousin's salary.

find by a digit to make the number divisible by 3 1234?
A digit to make the number divisible by 3 is by adding the digit 2 to the number 1234.
To make the number 1234 divisible by 3, we can find the sum of its digits and determine if it is divisible by 3. If the sum of the digits is divisible by 3, then the original number is also divisible by 3.
Let's calculate the sum of the digits in 1234:
1 + 2 + 3 + 4 = 10
The sum of the digits is 10. Since 10 is not divisible by 3, we need to add or subtract a digit to make the sum divisible by 3.
To find the digit we need to add or subtract, we can use the fact that the difference between the original sum and the next multiple of 3 is the required digit.
The next multiple of 3 greater than 10 is 12 (12 - 10 = 2). Therefore, we need to add 2 to the number 1234 to make it divisible by 3.
1234 + 2 = 1236

Choose the best graph that represents the linear equation:
-x = 2y + 1
The line slants downward from left to right, indicating that as x increases, y decreases.
The given linear equation is -x = 2y + 1. To represent this equation graphically, we need to rearrange it into the slope-intercept form, which is y = mx + b, where m represents the slope and b represents the y-intercept.Rearranging the given equation, we get:2y = -x - 1
Dividing both sides by 2:y = (-1/2)x - 1/2
The slope of the line is -1/2, which means that for every unit increase in x, y decreases by 1/2 unit. The y-intercept is -1/2, indicating that the line intersects the y-axis at (0, -1/2).
Based on this information, the best graph that represents the linear equation y = (-1/2)x - 1/2 is a straight line with a negative slope of -1/2, starting at the point (0, -1/2) and extending infinitely in both directions.
