What numbers are divisible by 2 and 5 but not 3

The plotted line on the graph represents all the points (x, y) that satisfy the equation [tex]\( y - 3 = \frac{1}{2}(x + 2) \)[/tex].

The graph of the equation [tex]\( y - 3 = \frac{1}{2}(x + 2) \)[/tex] has been plotted. Here are the steps to plot this graph:

1. Rearrange the equation: Convert the given equation into slope-intercept form, [tex]\( y = mx + c \)[/tex], which makes it easier to graph.

2. Calculate the y-intercept: This is the point where the line crosses the y-axis, which occurs when [tex]\( x = 0 \)[/tex]. Substituting [tex]\( x = 0 \)[/tex] into the equation gives [tex]\( y = 4 \)[/tex]. So, the y-intercept is (0, 4).

3. Calculate the slope: The slope is [tex]\( \frac{1}{2} \)[/tex] which means that for every 2 units the graph moves horizontally to the right, it moves 1 unit up.

4. Plot the y-intercept: Start at the y-intercept (0, 4) on the graph.

5. Use the slope to find another point: From the y-intercept, move right 2 units and up 1 unit to find another point on the line. You could also move left 2 units and down 1 unit for another point.

6. Draw the line: Connect the points with a straight line to complete the graph.

Answer:

x = - 3 - √33 / 2

x = + 3 + √33 /2

or

x=1.37228132...

x=−4.37228132...

Step-by-step explanation:

The two values of x that are roots of the equation x^2+3x-6=0 are approximately x ≈ -4.16 and x ≈ 1.16.

To find the two values of x that are roots of the equation x^2+3x-6=0, we can use the quadratic formula. The formula is:

x = (-b ± √(b^2 - 4ac)) / 2a

In this case, a = 1, b = 3, and c = -6. Plugging in these values, we get:

x = (-3 ± √(3^2 - 4(1)(-6))) / 2(1)

Simplifying further:

x = (-3 ± √(9 + 24)) / 2

x = (-3 ± √33) / 2

So the two values of x that are roots of the equation are approximately x ≈ -4.16 and x ≈ 1.16.

Formula for area of Circle is;

A = πr²

Thus;

πr² = 1500

r = √(1500/π)

Now, they want to double the radius. Thus approximate area of the new playground is;

A_new = π * [2√(1500/π)]²

A_new = π * [4(1500/π)]

Answer:

Cashew= 36 pounds

Walnut= 4 pounds

Step-by-step explanation:

Given: Cost of Cashew= $1.58 per pound

           Cost of walnut= $0.78 per pound

           Total weight of mixture= 40 Pound

           Cost of mixture= $1.50 per pound.

Lets assume the amount of cashew added in the mixture be "x".

∴ Amount of Walnut in the mixture will be [tex](40-x)[/tex]

Now, forming an equation to total cost and weight of mixture.

⇒ [tex]1.58\times x+0.78 \times (40-x)= 40\times 1.50[/tex]

Using distributive property of multiplication

⇒ [tex]1.58x+31.2-0.78x= 60[/tex]

⇒[tex]0.8x+31.2= 60[/tex]

Subtracting both side by 31.2

⇒[tex]0.8x= 60-31.2[/tex]

⇒[tex]0.8x= 28.8[/tex]

Dividing both side by 0.8

⇒[tex]x= \frac{28.8}{0.8}[/tex]

∴ [tex]x= 36\ pounds[/tex]

Hence, Amount of cashew added in the mixture of nuts is 36 pounds.

Next finding the amount of walnut added in the mixture.

subtituting the value of x

Amount of walnut in the mixture= [tex](40-x)[/tex]

⇒ Amount of walnut in the mixture= [tex](40-36)= 4\ pounds[/tex]

Hence, 4 pounds of walnut added in the mixture.

Final answer:

To make a 40-pound mixture of nuts that costs $1.50 per pound, mix 36 pounds of cashews, which cost $1.58 per pound, with walnuts costing $0.78 per pound.

Explanation:

Let's approach this mixture problem using the concept of weighted averages. We know we want to make a 40-pound mixture of cashews and walnuts that costs $1.50 per pound.

The cashews cost $1.58 per pound and the walnuts cost $0.78 per pound. To find out how many pounds of cashews to mix with walnuts, we can set up the equation:

Let x be the amount of cashews needed.

Since the total weight of the mixture is 40 pounds, the amount of walnuts needed would be 40 - x pounds.

Using the equation for the total cost of the mixture: 1.58x + 0.78(40 - x) = 1.50(40),

we solve for x:

Therefore, to obtain a 40-pound mixture costing $1.50 per pound, a person should mix 36 pounds of cashews with walnuts.

The number that times 10 equals 0.3 is 0.03. This exercise relates to understanding decimal places and exponents, where for instance, 10⁻³ represents 0.001 and signifies that the decimal point is shifted three places to the left.

To find what number times 10 equals 0.3, we need to solve the following equation:

x × 10 = 0.3

To find x, we divide both sides of the equation by 10:

x = 0.3 / 10

x = 0.03

Therefore, 0.03 times 10 equals 0.3.

Answer: A. 2,604

Step-by-step explanation:

According to the given information the number of sets in rows following arithmetic progression (in short form AP).

Where , 23rd term is 65.

Common difference = 65-63=2

nth term in AP: [tex]a_n=a+(n-1)d[/tex]

For n= 23 , we have [tex]a_{23}=65[/tex] , d= 2

[tex]23=a+(23-1)2\\\\ 23= a+(22)2\\\\ 23=a+44\\\\ a=44-23=21[/tex]

Formula for the sum of first n terms in AP= [tex]S_n=\dfrac{n}{2}[2a+(n-1)d][/tex]

Since, There are 42 rows in the auditorium.

Then,

[tex]S_{42}=\dfrac{42}{2}[2(21)+(42-1)2]\\\\=21(42+82)\\\\=21(124)=2604[/tex]

Hence, the the auditorium contains 2,604 seats.

Thus , the correct answer is A. 2,604

We want to find the total number of seats in the auditorium, knowing that the number of seats is given by an arithmetic sequence.

The correct option is A: there are 2,604 seats in total.

We know that in the row before you (the number 22) there are 63 seats, in your row (number 23) there are 65 seats, and in the next row there are 67 seats, then we can write the 3 terms of a sequence:

[tex]a_{22}= 63\\a_{23} = 65\\a_{24} = 67[/tex]

Is simple to see that this is an arithmetic sequence, such that the difference between consecutive terms is 2, then the number of seats in the n-th row is given by:

[tex]a_n = a_{n-1} + 2[/tex]

or:

[tex]a_n = a_1 + (n - 1)*2[/tex]

Using this second equation, we can find the value of the first term of the sequence:

[tex]a_{23} = 65 = a_1 + 2*(23 - 1)\\\\65 - 44 = a_1 = 21\\[/tex]

Now, if we define d as the difference between consecutive terms in an arithmetic sequence, the sum of the first N terms is given by:

[tex]S(N) = N*(2*a_1 + (N - 1)*d)/2[/tex]

Here we have a total of 42 rows, so we use N = 42.

d =2

a₁ = 21

Then the total number of seats is:

[tex]S(N) = 42*(2*21 + (42 - 1)*2)/2 = 2,604[/tex]

This means that the correct option is A: there are 2,604 seats in total.

Answer:

Step-by-step explanation:

Step-by-step explanation: Notice that the fractions that we're comparing in this problem have different denominators.

When fractions have different denominators, they're called unlike fractions. To compare unlike fractions, we must first get a common denominator.

The common denominator of 4 and 3 will be the least common multiple of 4 and 3 or 12. To get a 12 in the denominator of 1/4, we multiply the numerator and the denominator by 3 which gives us 3/12. To get a 12 in the denominator of 1/3, we multiply the numerator and the denominator by 4 which gives us 4/12.

Now we have the fractions 3/12 and 4/12.

The fraction with the greater denominator is larger so 4/12 is bigger which means that 1/3 is bigger.

1/4 is not greater than 1/3. In fact it is less than 1/3.

We have two fractions, 1/4 and 1/3.

We know that,

For a fraction, when the value of the denominator increases, the value of the fraction decreases.

So here the denominator of 4 is greater than 3.

So 1/4 is less than 1/3.

In other words, 1/4 can be defined as a part when 1 is divided in to 4 parts.

1/3 is one part when 1 is divided in to 3 parts.

So clearly, 1/4 < 1/3.

Hence 1/4 is less than 1/3.

Answer:

Therefore the correct option is a.) The standard deviation is 0.0998. The 10% condition is met because it is very likely there are more than 250 catfish in the river.

Step-by-step explanation:

i) Let p = 0.47

ii) therefore q = 1 - 0.47 = 0.53

iii) sample size, n =25

iii) standard deviation = [tex]\sqrt{\frac{p \times q}{n} } = \sqrt{\frac{0.47 \times 0.53}{25} } = 0.0998[/tex]

Therefore the correct option is

a.) The standard deviation is 0.0998. The 10% condition is met because it

    is very likely there are more than 250 catfish in the river.

The standard deviation of the sampling distribution of the sample proportion is 0.0998. To determine whether the 10% condition is met, the total population of catfish should be at least 10 times the sample size.

The question asks about determining the standard deviation of the sampling distribution of the proportion of catfish in a river and if the 10% condition is met for the sampling distribution to be approximately normal. First, to calculate the standard deviation of the sampling distribution of the sample proportion (p-hat), we use the formula √[(p(1-p))/n], where p is the population proportion and n is the sample size. In this case, p = 0.47, so 1 - p = 0.53, and n = 25. The standard deviation is then √[(0.47*0.53)/25], which is approximately 0.0998.

Next, the 10% condition checks whether we can consider the population large enough that the sample size doesn't affect the population proportion notably when taking without replacement. This condition states that the sample size, n, should be no more than 10% of the population. If there are indeed more than 250 fish in the river (10 times the sample size), we can be confident that the 10% condition is met. If not, the condition is not met.

Therefore, the correct response would state the standard deviation and appropriately evaluate whether the 10% condition is met based on the estimated number of catfish in the river.
