When the population has a mean of 30, if 3 points are added to each score, the mean for the new distribution is 33.

It should be noted that mean simply means the average of a given set of numbers that are given. The entire group about whom you want to make conclusions is referred to as a population. The particular group from which you will gather data is known as a sample. The sample size is always smaller than the population as a whole. A population in research doesn't usually refer to humans.

In this case, the population has a mean of 30 a and 3 points are added to each score.

In this case, the new mean will be the addition of the numbers. This will be illustrated as:

= 30 + 3

= 33

The place value of the underlined digit (6) is tens of thousands and should be rounded to 70,000.

A place value simply refers to a numerical value (number) which denotes a digit based on its position in a given number and it includes the following:

In this scenario, the place value of the underlined digit (6) is tens of thousands and 9 is the next digit to six (6). Therefore, we would add one (1) to the underlined digit (6) and then change all of the other digits to zero (0) as follows:

69,807 = 70,000

Slope is [tex]\frac{-2}{3}[/tex] of coordinates (6,5) and (9,-7).

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. [1] The letter m is frequently used to represent slope; however, there is no obvious reason for this. The slope of a curve at a point in differential calculus is defined as the slope of the tangent line at that point as a generalization of this practical definition. The slope can be determined between any two locations when the curve is represented by a series of points in a diagram or list of point coordinates. Maybe when the curve is represented as a continuous function.

Given Data

coordinates - (6,-5) and (9,-7)

slope of the line denoted as m

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

m = [tex]\frac{-7-(-5)}{9-6}[/tex]

m = [tex]\frac{-2}{3}[/tex]

The answer is a) 27/6 b) 1/2 c) 0.6 = 6/10 = 3/5 and their sum is 5.6

The four basic arithmetic operations in Maths, for all real numbers, are:

→ Addition (Finding the Sum; ‘+’)

→ Subtraction (Finding the difference;  ‘-’)

→ Multiplication (Finding the product; ‘×’ )

→ Division (Finding the quotient; ‘÷’)

In this given question ;

a) [tex]\frac{3}{4}[/tex] + 6

first take LCM so we will get : [tex]\frac{3+24}{6}[/tex] = [tex]\frac{27}{6}[/tex]

b) [tex]\frac{2}{4}[/tex]÷ 1

this implies [tex]\frac{1}{2}[/tex] ÷ 1 = [tex]\frac{1}{2}[/tex]× 1 = [tex]\frac{1}{2}[/tex]

c) [tex]\frac{3}{5}[/tex] = 0.6

If we were to solve a + b + c we get : 27/6 = 4.5

b= 1/2 = 0.5

so 4.5+ 0.5 + 0.6 = 5.6

Explanation:

He will cover 301.875 miles in 7.5 hours at a unit speed of 40.25 miles per hour.

A ratio that compares two amounts of different types of units is called a rate. When a unit rate is expressed as a fraction, the denominator is 1 unit.

Rate = Distance/Time

If Mr.Salcedo was driving at 120 3/4 miles in 3 hours, his unit rate will be calculated as:

Unit rate =[120 3/4]/3

Unit rate = 483/12

Unit rate = 40 1/4 miles/hr

This shows that he  drove 40 1/4 miles/hr.

The miles he drove in 7 1/2 hour is expressed as;

Miles driven = 161/4 * 15/2
Miles driven = 301.875 miles

Hence the miles that he will drive in 7.5 hours is 301.875miles and the unit rate is 40.25 miles/hr

An equation to represent this situation is |x - 102| = 10.

The greatest and least guesses that can be made without Houston winning a prize are 112 pounds and 92 pounds.

Given:

Actual Weight of Houston = 102 pounds

Now, if the guess is not within 10 pounds of his actual weight, Houston wins a prize.

An equation to represent this situation can be written as,

|x - 102| = 10

As we know a modulus function always generates a positive value.

We need the difference between the guessed weight and the actual weight to be exactly 10 pounds so we have applied modulus in the equation.

Now we utilize the above equation to determine the greatest and least guesses that can be made without Houston winning a prize.

The greatest guessed weight will be,

x - 102 = 10 ⇒ x = 102 + 10 ⇒ x = 112 pounds

The least guessed weight will be (the modulus value will be negative in this case)

-x + 102 = 10 ⇒ x = 102 - 10 ⇒ x = 92 pounds

Solve for x to get,

6x = 19.86x=19.8

Answer:

$3.30 for each bag of lemons

Step-by-step explanation:

We know that Omar only bought both lemons and eggs. We also know that the total amount of money he spent on groceries is $26.30 and that the eggs are worth $6.30 out of the total.

So, if we can subtract the cost of the eggs from his total cost of groceries to find how much the lemons cost. After that we can divide the cost of all the lemons, which is $19.80, by the number of bags, which is 6, to find how much each bag costs.

Based on the taxes in the first city and the tax in the second city as well as the total hotel tax paid in the two cities, the hotel charge for each city before taxes was:

The hotel charge before taxes was $500 higher in the second city than in the first. Assuming the charge in the first city was x, the charge in the second city was:

= x + 500

The total charge in the first city would be:

0.065x + 0.06(x + 500) = 748.75

0.065x + 0.06x + 30 = 748.75

0.125x + 30 = 748.75

0.125x = 748.75 - 30

0.125x = 718.75

x = 718.75/0.125

x = $5,750

The total charge in the second city would be:

= 5,750 + 500

= $6,250

In conclusion, the charges in the first and second cities are $5,750 in the first city and $6,250 in the second city.

If the width of a rectangle is 15 cm less than the length and the perimeter of the rectangle is 150 cm, then the length is 45 cm and width is 30 cm

The width of a rectangle is 15 cm less than the length

Consider the length of the rectangle as x

The the width of the rectangle = x-15

The perimeter of the rectangle = 150 cm

The perimeter of the rectangle = 2(l+w)

Where l is the length and w is the width

Substitute the values in the equation

2(x+(x-15))=150

2(2x-15)=150

4x-30 = 150

4x = 180

x = 45 cm

The width of the rectangle = x-15

= 45-15

The smallest number of signs that he can sell to have an income of $300 in one week is 12.

The price of one sign is x

Number of signs he sells per week = 37-x

The total earning from selling these is  x(37-x)  which is given as $300

(37- x) x = 300

37x - x² = 300

x² - 37x + 300 = 0

As per formula to find base in a quadratic equation

[tex]x =\frac{37 - \sqrt{37^{2}-4 . 1 . 300 } }{2 . 1} \\x =\frac{37 - \sqrt{1369-1200 } }{2} \\x =\frac{37 - \sqrt{169 } }{2} \\x = \frac{37-13}{2}\\ x = \frac{24}{2}\\ x = 12[/tex]

The other base can be

[tex]x =\frac{37 + \sqrt{37^{2}-4 . 1 . 300 } }{2 . 1} \\x =\frac{37 + \sqrt{1369-1200 } }{2} \\x =\frac{37 + \sqrt{169 } }{2} \\x = \frac{37+13}{2}\\ x = \frac{50}{2}\\ x = 25[/tex]
