Factor completely 25x +60

Answer:

It is not possible

Step-by-step explanation:

First 6 people have 9 friends and since 6 people can have totally the same friends which could all be each other, we would have 5 friends(from same 6 people) + 4 friends(not from the 6). Therefore we would have total 9 people/students

In second group of 8 people, their friends could entirely be the same be the same as the first group's friends or they could all be each other's friend hence just an additional 8 students to the population

In the third group of 11 people/students, same thing could apply as above but total number of students would always surpass 25 with the additional population. Example 9+8+11= 28

Therefore it is not possible that 25 students would each have those number of friends.

Answer:

median for 9,1,9,6,5 is 6 and for 2,10,7,1 is 4 1/2

I got it by lining up the first numbers    1,5,6,9,9 and 6 was middle    second one i lined it up     1,2,7,10 and 2 and 7 were middle so added them together and divided by 2 and got 4 1/2

Answer:

[tex]\frac{a}{b}[/tex]

Step-by-step explanation:

For this problem, if we really wanted to be precise, we could go through and do the slope equation for all of the lines. However, this graph is clear enough that we can just count the points.

On line A, we can just follow the line and see that the slope is -1 because each point goes down 1 and over 1.

Line B has a slope of -2. It goes down 2 and over 1.

Line C has a slope of 2; up 2 and over 1.

If we look at our three slopes, -1, -2, and 2, we can see that the only way for the ratio to be 1/2 is for line A over line B. This is because a negative over a negative is a positive.

Hope this helps!

Step-by-step explanation:

The amount she will have left after writing a check for $23.99 is $13.26. The correct answer would be an option (C).

Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

Tricia has $37.25 in her account, if she writes a check for $23.99, to find the amount left after that we need to subtract the check amount from her initial amount.

⇒ initial amount - check amount

⇒ $37.25 - $23.99

Apply the subtraction operations, and we get

⇒ $13.26

Therefore, the amount she will have left after writing a check for $23.99 is $13.26.

Answer:

Kristen should walk 12 miles to catch up with Paul

Step-by-step explanation:

Paul = 2hrs earlier

      = walks at 3 miles per hour

      = 3miles x 2 hrs = 6 miles

covers 6 miles at the time Kristen starts

Kristen = 4 miles per hour

Paul has a lead of 6 miles.

if Kristen walks another hour of 4 miles she would have covered 8 miles and Paul would have covered 9 miles and if  Kristen were to cover one more hour,

Kristen would be at 12 and so would Paul.

Kristen should walk 12 miles to catch up with Paul

Answer:

-3

Step-by-step explanation:

Answer:

[tex]r=-3[/tex]

Step-by-step explanation:

We have the equation:

[tex]\displaystyle \frac{1}{3}r+1=-\frac{2}{3}r-2[/tex]

And we would like to solve for r.

First, we can multiply both sides by the denominator 3. This will remove the fractions. So:

[tex]\displaystyle 3(\frac{1}{3}r+1)=3(-\frac{2}{3}r-2)[/tex]

Distribute:

[tex]\displaystyle r+3=-2r-6[/tex]

Now, we can add 2r to both sides:

[tex]3r+3=-6[/tex]

And we can also subtract 3 from both sides:

[tex]3r=-9[/tex]

Finally, we can divide both sides by 3 to get:

[tex]r=-3[/tex]

Answer:

337.41366

Step-by-step explanation:

Given that:

Mean = 331 grams

Standard deviation = 23 grams

Sample size (n) = 15

P(Z < x) = 14% = 0.14

Obtain the Zscore corresponding to (1 - 0.14) = 0.86

P(z < 0.86) = 1.08

Zscore = 1.08

Zscore = (x - mean) / s/√n

1.08 = (x - 331) / 23/sqrt(15)

1.08 = (x - 331) / 5.9385744

X - 331 = 6.4136604

X = 6.4136604 + 331

X = 337.41366

Answer:

750

Step-by-step explanation:

A relative value indicating hundredth parts of any quantity. 1.5 is 0.2% of 750.

A relative value indicating hundredth parts of any quantity.

We need to find the number whose 1.5 is 0.2%.(one point five is zero point two percent)

Let x be the number which is 0.2% of a number 1.5.

The percentage value is converted to decimal value by dividing with 100.

0.2/100×x=1.5

zero point two divided by hundred time of x is equal to one point five.

0.002x=1.5

Divide both sides by 0.002

x=1.5/0.002

x equal to one point five by zero point zero zero two.

x=750.

x equal to seven hundred fifty.

Hence 1.5 is 0.2% of 750.

Answer:

(4n − 1)(n − 4)

Explanation:

Factor 4n² − 17n + 4

4n² − 17n + 4

= (4n − 1)(n − 4)

Answer:

(4n − 1)(n − 4)

The factors of the expression [tex]4n^2-17n+4[/tex] are

Mathematically, an expression is a combination of numbers, variables, operations, and functions that are combined according to specific rules to represent a mathematical computation or relationship. It can be thought of as a mathematical phrase or formula.

To factorize the quadratic expression [tex]4n^2 - 17n + 4[/tex], we need to find two binomial factors that, when multiplied, result in the given expression.

The factored form will have the following structure:

(An + B)(Cn + D)

To find the values of A, B, C, and D, we can use various methods such as factoring by grouping, quadratic formula, or completing the square. In this case, we will use the factoring by grouping method.

Step 1: Multiply the coefficient of the leading term (4) by the constant term (4). The result is 16.

Step 2: We need to find two numbers that multiply to give 16 and add up to the coefficient of the linear term (-17). After considering the possible pairs of numbers, we find that -16 and -1 meet these criteria.

Step 3: Rewrite the middle term (-17n) using -16n - n:

= [tex]4n^2 - 16n - n + 4[/tex]

Step 4: Group the terms and factors by grouping:

= [tex](4n^2 - 16n) - (n - 4)[/tex]

= 4n(n - 4) - 1(n - 4)

Step 5: Factor out the common binomial factor:

(n - 4)(4n - 1)

Therefore, the factored form of the quadratic expression [tex]4n^2 - 17n + 4[/tex] is (n - 4)(4n - 1).

Answer:

50 packs.

Step-by-step explanation:

Given the following data;

Length = 28 feet

Width = 25 feet

Pack of seeds = 14 ft²

Since Kevin's backyard is a rectangle, we would find its area.

Area of rectangle = length * width

Substituting into the equation, we have;

Area of rectangle = 28 * 25

Area of rectangle = 700 ft²

Now to find the amount of pack of seeds required to cover the backyard.

Amount of pack of seeds = 700/14

Amount of pack of seeds = 50 packs.
