​

Answer:

I just took the test the answer is: None

Step-by-step explanation:

Answer:

Work:

first you want to change 1/2 so the denominator is a 4

1/2 is equivalent to 2/4

now you have -1 1/4 + 2/4

then you want to get rid of the whole number and make -1 1/4 into a fraction

-1 is -4/4 so add that to the 1/4

now you have -5/4 + 2/4

you can add that now easily and get -3/4

A permutation is a process of putting items or pieces in a certain order. Combinations are a method of picking things or pieces from a set of objects or collections when the order of the objects is irrelevant.

No of student=10

Students to be choosen=3

The ways are there to choose the students are found with the help of combination as;

If n is the number of the ways:

n= 10C₃

[tex]\rm nCr = \frac{n!}{r!(n-r)!}\\\\[/tex]

Where n is the total of students and r is the teacher to be chosen:

[tex]\rm 10 C_3= \frac{10 !}{3!7!}\\\\ 10 C_3= \frac{3628800}{30240} \\\\ n=120[/tex]

Answer:

3

Step-by-step explanation:

The assumed frequency of defects is 2/16.

When we apply this rate to 24, (2/16)*24, we get 3.

Therefore, we can assume around 3 defective boxes tomorrow.

Answer:

n = 2.8

Step-by-step explanation:

We need to solve the equation 5n+7 =21 to find the value of n.

Adding -7 on both sides

5n +7 -7 = 21 -7

5n = 14

Dividing both sides by 5

5n/5 = 14/5

n = 14/5

n = 2.8

Y=-2/5x -1 is the answer I believe, if anything check Photomath, that should be the right slope double check the y-intercept by plugging it in with your points provided to u

Answer:y = -2x + 7

Step-by-step explanation:

The equation of a straight line when two points are given is y - y1 = m(x - x1) but m is gradient which is y2 - y1 / x2 - x1

Substitute the points (3 ,1 ) and (7 , -7)

To the gradient equation and solve for the gradient which is m = -2 .Now with the gradient and the first point (3 , 1) solve for the equation

:• y - 1 = -2(x -3 )

y - 1 = -2x +6

. y = -2x + 7

Answer: 2 pizzas with 2.50 left

Step-by-step explanation: First you subtract the 3.50 from the 20, that'll leave you with 16.50 and then from there you subtract 7 from it until you can't anymore

Division is a method of distributing a group of things into equal parts.

According to the given question, we have the following data:

So, first of all, we have to pay the delivery charge whether we are ordering a single or bulk. That's why we have to deduct that from the total Sebastian has.

$20 - $3.50 = $16.50

So, now Sebastian has $16.50.

Now, each pizza is for $7.

So, it's clear now that, Sebastian has to divide his total amount by the price of each pizza to get how many pizzas he can order.

Number of pizzas Sebastian can order = (Total amount Sebastian has / price of each pizza)

= ($16.50 / $7)

= 2.36

But wait how can he order a fraction of pizzas so we have to take 2 as our answer.

Therefore, Sebastian could order a total of 2 pizzas.

Three methods to solve the equation are Division as Repeated Subtraction,Using Fraction Division Formula,Using Decimal Conversion.

I'll approach this problem using three different methods:

Method 1: Division as Repeated Subtraction

Dividing [tex]\( \frac{1}{3} \)[/tex] by 5 means finding out how many times 5 can be subtracted from 1/3

[tex]\( \frac{1}{3} - 5 = - \frac{14}{3} \)[/tex]

So, you can subtract 5 from 1/3 approximately 0 times with a remainder of [tex]\( - \frac{14}{3} \).[/tex]

Method 2: Using Fraction Division Formula

To divide a fraction by a number, you can multiply the fraction by the reciprocal of the number.

[tex]\( \frac{1}{3} \div 5 = \frac{1}{3} \times \frac{1}{5} \)[/tex]

[tex]\( \frac{1}{3} \times \frac{1}{5} = \frac{1 \times 1}{3 \times 5} \)[/tex]

[tex]\( \frac{1}{3} \div 5 = \frac{1}{15} \)[/tex]

So, [tex]\( \frac{1}{3} \div 5 = \frac{1}{15} \).[/tex]

Method 3: Using Decimal Conversion

Converting 1/3 to a decimal gives [tex]\( 0.3333... \)[/tex]

Then, dividing 0.333 by 5 gives:

[tex]\( 0.3333... \div 5 \approx 0.0667 \)[/tex]

So, [tex]\( \frac{1}{3} \div 5 \approx 0.0667 \).[/tex]

These are three different ways to solve the problem [tex]\( \frac{1}{3} \div 5 \).[/tex]

Answer:

n < 6

Step-by-step explanation:

n/-3 + 8 > 6

Subtract 8 from each side

n/-3 + 8 -8> 6-8

n/-3 > -2

Multiply each side by -3 to isolate n.  Remember to flip the inequality since we are multiplying by a negative

n/-3 * -3 < -2 *-3

n < 6

[tex]P(x)[/tex] has degree 3, so it takes the general form

[tex]P(x)=ax^3+bx^2+cx+d[/tex]

It has a root [tex]x=1[/tex] of multiplicity 2, which means [tex](x-1)^2[/tex] divides [tex]P(x)[/tex] exactly, and it has a root of [tex]x=-3[/tex] of multiplicity 1 so that [tex]x+3[/tex] also is a factor. So

[tex]P(x)=a(x-1)^2(x+3)[/tex]

Expanding this gives

[tex]P(x)=a(x^3+x^2-5x+3)=ax^3+ax^2-5ax+3a[/tex]

[tex]\implies\begin{cases}a=b\\-5a=c\\3a=d\end{cases}[/tex]

The [tex]y[/tex]-intercept occurs for [tex]x=0[/tex], for which we have

[tex]P(0)=d=2.1[/tex]

Then

[tex]3a=d\implies a=0.7[/tex]

[tex]a=b\implies b=0.7[/tex]

[tex]-5a=c\implies c=-0.14[/tex]

So we have

[tex]\boxed{P(x)=0.7x^3+0.7x^2-0.14x+2.1}[/tex]

Answer:

[tex]0.069\ kg[/tex]

Step-by-step explanation:

we know that

1 kg=1,000 g

so

using proportion

Find out how many kilograms are 69 grams

Let

x -----> the weight in kg

[tex]\frac{1}{1,000}\frac{kg}{g} =\frac{x}{69}\frac{kg}{g}\\\\x=\frac{69}{1,000}\\\\x=0.069\ kg[/tex]

69 grams is equal to 0.069 kilograms.

To find how many kilograms 15 crackers weighing 69 grams is, convert 69 grams to kilograms by recognizing that there are 1000 grams in 1 kilogram.

15 crackers weigh 69 grams. To find how many kilograms this is, we need to convert grams to kilograms. There are 1000 grams in 1 kilogram. Therefore, 69 grams is equal to 0.069 kilograms.

Equilateral triangle: all sides are equal lengths, all angles are equal too

Scalene triangle: has three different sides, all angles are different

Isosceles triangle: 2 sides are equal, one isn’t, 2 angles are the same, one is different

Obtuse triangle: angles are larger than 90 degrees

Right triangle: angle forms a 90 degree angle

Those are the triangles :)

Answer:

63.36 years

Step-by-step explanation:

This is a compound interest problem and the following information has been provided;

Principal, P = 1200

Interest rate, r = 4%

Accumulated amount, A = 14400

We are required to determine the number of years for the principal to accumulate to the given amount. We use the compound interest formula;

[tex]A=P(1+r)^{n}[/tex]

We substitute the given values into the formula and solve for n;

[tex]14400=1200(1+\frac{4}{100})^{n}\\12=(1.04)^{n}\\[/tex]

The next step is to introduce natural logarithms;

[tex]ln12=nln(1.04)\\n=\frac{ln12}{ln1.04}\\n=63.36[/tex]

Thomas has invested $1,200 at a 4% interest rate. Using the formula for compound interest and solving for time, it will take approximately 29.1 years for his account balance to reach $14,400.

Thomas has invested an amount of $1,200 into an account with a 4% interest rate. This type of problem involves the use of the formula for compound interest. The general formula for compound interest is: A = P(1 + r/n)^(nt), where:

In this case, we assume the interest is compounded annually, so n = 1. We rearrange the formula to solve for t, giving us the formula t = log(A/P) / log(1 + r).

Substituting the given values into the formula, we get t = log(14400/1200) / log(1 + 0.04), which gives a result of approximately 29.1 years. So, it will take around 29.1 years for the account balance to reach $14,400.

Answer:

solutions to f(x)=g(x) are x=-1 and x=8

Step-by-step explanation:

The minimum point of the parabola will be found at ...

x = -b/(2a) . . . . . where a, b, c are the coefficients of ax²+bx+c

For g(x) = x² -6x -7, the minimum will be at x=-(-6)/(2·1) = 3. The minimum value is ...

g(3) = 3² -6·3 -7 = -16

so the vertex (minimum point) you want to plot is (3, -16). Since the coefficient of x² is 1, there is no vertical scaling, so when the value of x differs from 3 by 1 unit, the value of g(x) will be 1² = 1 unit higher. That is, g(4) = -15, so (4, -15) is another point on the parabola.
