What is Y value called?

Answer: 148

Step-by-step explanation: To find the surface area, add up all the side areas. Since we know that the opposite side of one side is the same, we can do 2(4 *5) + 2(6*5) + 2(4*6). This will get 148.

Probability that the person randomly chosen from the town's population is under 18 or employed part time is the probability of a randomly chosen person is under 18 plus the probability of a randomly chosen person is  employed part-time subtracting the probability that they are both under 18 and employed part-time.

In order to find the probability that a person is under 18 or employed part-time, you would need to know the proportion of the population that is under 18 and the proportion of the population that is employed part-time. Then you can use the following formula:

P(under 18 or part-time) = P(under 18) + P(part-time) - P(under 18 and part-time)

Where P(under 18 and part-time) is the probability that a person is under 18 and employed part-time at the same time.

Let n be a 5-digit number, and let q and r be the quotient and the remainder, respectively, when n is divided by 100. For(B) 8181 values of n is q + r divisible by 11.

5 digit Number:

A 5 digit number is a 5 digit number where the first digit is 1 or greater than 1 and the remaining digits can be any digit from 0 to 9. It starts at ten thousand (10,000) and goes up to 99,999 (99,999).

Given:

Let n be a 5-digit number, and let q and r be the quotient and the remainder, respectively, when n is divided by 100.

When a five digit number is divided by 100, we get first three digits as quotient and last two digits as remainder. Therefore q can be any integer from 100 to 999 and r can be from 0 to 99

So for each value of 9 x 100 = 900 , possible value will be q = 100/11 = 9

Now,

q + r ≡ 0 (mod 11) will be possible values of r.

Since there is one extra , 900 / 11 = = 81

Hence, q + r ≡ 0 (mod 11)

So, possible values of n such that q + r = 0(mod 11) is 9 x 100 + 1 x 81

So, it will be 8100 + 81 = 8181

The coordinates of the point P along the directed line segment AB are (-6, -4).

In this scenario, line ratio would be used to determine the coordinates of the point P on the directed line segment that partitions the segment into a ratio of 1 to 4.

Mathematically, line ratio can be used to determine the coordinates of P and this is modeled by this mathematical expression:

P(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

Substituting the given parameters into the line ratio formula, we have;

P(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

P(x, y) = [(1(-2) + 4(-7))/(1 + 4)],  [(1(0) + 4(-5))/(1 + 4)]

There are a total of 126 different committees that can be formed with at least three women.

The number of different committees that can be formed with at least three women from a group of six women and three men can be calculated using the Combination formula. The Combination formula is defined as follows:

C(n,r)=n!/r!(n-r)!

where n is the total number of elements in the group and r is the number of elements to be selected from it.

In this case, n = 9 (6 women + 3 men) and r = 5 (the size of the committee).

Therefore, the number of different committees that can be formed with 3 women is:

C(9,5) = 9!/(5!*(9-5)!) = 9!/5!*4! = 126

Curvature is one of many ideas in mathematics that are strongly related to geometry. According to common sense, curvature is the deviation of a curve or face from a plane or a straight line. In mathematics, curvature refers to the rate at which a curve changes direction in relation to the distance traveled along the curve. The pace at which a curve spins is generally referred to as its curvature. The direction of the curve is indicated by the tangent line or velocity vector, which means that the curvature is roughly equal to the rate of rotation of the tangent line or velocity vector.

The equation y = mx + c is the general equation of any straight line where m is the gradient of the line (how steep the line is) and c is the y-intercept (the point at which the line crosses the y -axis).

This is a linear function,

let's say the equation is y =ax + b,

the points (1.5, 350) and (4, 400)

a = (400-350) /(4 - 1.5)

= 50/2.5

= 20

y = 20x + b,

350 = 20(1.5) + b

350 = 30 + b

350 -30 = b

b = 320

y = 20x + 320

so, in 2008,

x =15,

y = 20(15) + 320 = 300 + 320 = 620

A normal distribution is the sampling distribution of averages or proportions from a large number of independent trials that approximately follows the normal curve. The expectation of a sample proportion or average is the corresponding population value.

The normal approximation is used to approximate probabilities because it is often easier to use the area under the normal curve compared to the sum of many discrete values.

The result tells us that t, the number of tickets, must be less than or equal to 6.4

Since t represents the number of tickets, it must be a whole number, so the greatest number of tickets Jessica can buy is 6.

Answer:

a) To find out how many pounds a 137 ounce baby weighs, we divide the weight in ounces by the number of ounces per pound.

137 ounces / 16 ounces/pound = 8.5625 pounds

Therefore, a 137 ounce baby weighs 8.5625 pounds.

b) To find out how much heavier the second baby is, we first convert the weight of the second baby from pounds to ounces.

We know there are 16 ounces in one pound, so we can multiply 9.375 (9 3/8) by 16 to find out how many ounces the second baby weighs.

9.375 * 16 = 150.4 ounces

Now we can subtract the weight of the first baby from the weight of the second baby to find out the difference in weight.

150.4 - 137 = 13.4 ounces

Therefore, the second baby is 13.4 ounces heavier than the first baby.

To determine if Tim is correct in stating that he has paid his fair share of the total cost, we need to calculate the total cost of the dinner and compare it to the cost of the desserts Tim paid for.

Will paid for 2 pizzas at a cost of $3.75 each, for a total of 2 * $3.75 = $7.50

Tim paid for 3 desserts at a cost of $1.09 each, for a total of 3 * $1.09 = $3.27

The total cost of the dinner is $7.50 + $3.27 = $10.77

To check if Tim has paid his fair share, we need to compare the cost of the desserts he paid for ($3.27) to the total cost of the dinner ($10.77)

$3.27 is 30.3% of $10.77, meaning Tim paid for around 30% of the dinner.

In this case, it's not fair to say that Tim has paid his fair share of the total cost, since he paid for only around 30% of the dinner, and as such, this cost should be split among the three of them.

It would be more accurate to say that Tim has paid a portion of the dinner, but not his fair share.

If the derivative of a function is positive, then the function is increasing. If the derivative of a function is negative, then the function is decreasing.

1. Take a function, f(x).

2. Take the derivative of the function, f'(x).

3. If f'(x) is greater than 0, then the function is increasing.

4. If f'(x) is less than 0, then the function is decreasing.

To determine if a function is increasing or decreasing, the derivative of the function must be found. The derivative of a function is written as f'(x). If the derivative is greater than 0, then the function is increasing. If the derivative is less than 0, then the function is decreasing. This is because an increasing function has a positive slope, and a decreasing function has a negative slope. The derivative is the slope of the function, so if the derivative is positive, the function is increasing, and vice versa.
