In the first week of​ July, a record 1,060 people went to the local swimming pool. In the second​ week,105 fewer people went to the pool than in the first week. In the third​ week, 145 more people went to the pool than in the second week. In the fourth​ week, 199 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four​ weeks?

Answers

Answer 1

The percent decrease in the number of people who went to the pool over these four weeks is 15%.

How to calculate the percentage?

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

The number of people by the fourth week will be:

= 1060 - 105 + 145 - 199

= 901

The percentage decrease will be:

= (1060 - 901) / 1060 × 100

= 159/1060 × 100

= 15%

on a standardized test with a normal distribution, the mean was 64.3 and the standard deviation was 5.4. what is the best approximation of the percent of scores that fell between 58.9 and 75.1?

Answers

the best approximation of the percent of scores that fell between 58.9 and 75.1 is 4.

The mathematical average of a group of two or more numbers is called the mean. There are two different sorts of means that can be calculated: the arithmetic mean and the geometric mean. The arithmetic mean is calculated by adding all of the numbers in a set and dividing by the total number of integers in the set.

Find the difference between these two figures and the mean, divide it by the standard deviation of 5.4, and you will know how many standard deviations 75.1 and 61.5 are above and below the mean:

(75.1−64.3)/5.4

=2sd

According to the empirical rule, 95% of data are within two standard deviations of the mean.

In statistics, paired data, also known as ordered pairs, refers to two variables in a population's individuals that are linked together to ascertain their association. We refer to two datasets that are identical in length and in which each observation can be "paired" with an observation from the other dataset as having "paired data."

Second warning: 25 options

Three red cards: 24 options

A total of,

26 x 25 x 26 x 25 x 24 = 10,140,000.

But since all orders are equal, we divide by the number of orders for a five card hand:

5 x 4 x 3 x 2 x 1 = 5! = 120

So,

10,40,000 / 120 = 84,500.

Answer:

Option A for both questions

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

The first question

The graph indicates the inequality n ≤ 1, since highlighted part is to the left from the 1 and there is a closed circle.

Double both sides to get 2n:

n ≤ 1 ⇒ 2n ≤ 2

And add 5 to both sides to get 7:

2n + 5 ≤ 2 + 5 ⇒ 2n + 5 ≤ 7

This is matching the option A.

Question 12

The graph indicates the inequality p > 2, since highlighted part is to the right from the 2 and there is a open circle.

Multiply both sides by 5 to get 5p:

p > 2 ⇒5p > 10

Add 4 to both sides to get 14:

5p > 10 ⇒5p + 4 > 14

This is matching the option A.

Answers

The value of the required integral is 50π  where C is the positively oriented circle x2+y2=25

We are given a vector F = -yi + xj. A vector is a quantity with magnitude and direction that is commonly represented by a directed line segment, with length representing magnitude and orientation in space representing direction. We need to use the tangential vector form of Green's Theorem to compute the circulation integral ∫CF⋅dr where C is the positively oriented circle x² + y² = 25

Let the value of the integral be represented by the variable "I".

I = ∫∫[(/x)(x) - (/y)(-y)]dA

I = ∫∫[(1 - (-1)]dA

I = ∫∫2dA

I = 2∫∫dA

I = 2×(Area of the circle)

I = 2*(πr²)

I = 2*(π*25)

I = 50π

Hence, the value of the required integral is 50π.

a store owner currently sells bags of peanuts that cost $2.2 per pound and bags of almonds that cost $9.1 per pound. the owner wishes to make a 49 pound bag of a mixture of peanuts and almonds that costs $6.85 per pound. how many pounds of peanuts and almonds does the owner need?

Answers

To make a 49 pound bag of a mixture of peanuts and almonds that costs $6.85 per pound, the owner needs 15.98 pounds of peanuts and 33.02 pounds of almonds.

An algebraic expression is the combination of numbers and variables in expressing and solving a particular mathematical question. An equation is the equality of expressions.

Let x = pounds of peanuts in the mixture

y = pounds of almonds in the mixture

The owner wished to make a total of 49 pounds of mixture of peanuts ang almonds. Hence,

x + y = 49

x = 49 - y     (equation 1)

Bags of peanuts cost $2.2 per pound and bags of almonds cost $9.1 per pound, and the mixture should cost $6.85 per pound. Hence,

2.2x + 9.1y = 6.85(49)

2.2x + 9.1y = 335.65

Substitute equation 1 and solve for y.

2.2x + 9.1y = 335.65

2.2(49 - y) + 9.1y = 335.65

107.8 - 2.2y + 9.1y = 335.65

6.9y = 227.85

y = 33.02

pounds of almonds in the mixture = 33.02

Using equation 1, solve for x.

x = 49 - y

x = 49 - 33.02

x = 15.98

pounds of peanuts in the mixture = 15.98

From the given question,

Frames per one wing beat = 6 frames

Video shot at = 250 frames per second

We firstly find the time period

So, Time period (T) = 6/250

T= 0.024 s

Snce we have to find how many wing beats the dragonfly performs per second.

Per second number of wing beats = 1/T

Per second number of wing beats = 1/0.024

A group of students were discussing the integumentary system and the use of transdermal (TD) patches to administer medication. TD patches deliver a consistent dose of medication that diffuses at a constant rate through the skin into the bloodstream.
