Answer 1

Answer:

  f = 2.75p

Step-by-step explanation:

You can see that the amount of flour for 6 cakes is double the amount for 3 cakes, so the amount of flour is proportional to the number of cakes. An equation for a proportional relationship will have the form ...

  f = kp

We can find the value of k from any column in the table.

  8.25 = k(3) . . . . using the values in the first column

  8.25/3 = k = 2.75 . . . . . divide by 3

The equation is ...

  f = 2.75p

_____

Additional comment

If the input doubles, but the output does not, then the relationship is not proportional. We ordinarily expect recipes to have proportional relationships.

Solve the system of equations -x + 2y = –2 and 6x – y = -43 by combining
the equations.

Answers

Answer:

{x,y}={-8,-5}

Step-by-step explanation:

/ Solve equation [2] for the variable  y

 [2]    y = 6x + 43

// Plug this in for variable  y  in equation [1]

  [1]    -x + 2•(6x+43) = -2

  [1]    11x = -88

// Solve equation [1] for the variable  x

  [1]    11x = - 88

  [1]    x = - 8

// By now we know this much :

   x = -8

   y = 6x+43

// Use the  x  value to solve for  y

   y = 6(-8)+43 = -5

Solution :

Factinate claims that 84% of teenagers think highly of their mother. To investigate this claim, a school psychologist selects a random sample of 150 teenagers and finds that 135 think highly of their mother. Do these data provide convincing evidence that the true proportion of teens who think highly of their mother is greater than 0.84?
1. State appropriate hypotheses for performing a significance test. Be sure to define the parameter of interest The school psychologist performed the significance test and obtained a P-value of 0.0225.
2. Explain what it would mean for the null hypothesis to be true in this setting.
3. Interpret the P-value.
4. What conclusion would you make at the a = 0.05 level?

Answers

Use the z-distribution, we have that:

1.

The null hypothesis is of [tex]H_0: p = 0.84[/tex].

The alternative hypothesis is of [tex]H_1: p > 0.84[/tex].

2. It would mean that at most 84% of teenagers think highly of their mother, as we could not conclude that the proportion is more than 84%.

3. We are working with a right-tailed test, hence it means that there is a 0.0225 = 2.25% probability that at least 0.9 = 90% of teenagers think highly of their mother.

4. The p-value is of 0.0225, which is less than the significance level of 0.05, which means that we would reject the null hypothesis.

How the p-value influences the decision?If the p-value is less than the significance level, the null hypothesis is rejected.If the p-value is more than the significance level, the null hypothesis is not rejected.

Item 1:

At the null hypothesis, we test if the proportion of teenagers that think highly of their mother is of 84%, hence:

[tex]H_0: p = 0.84[/tex]

At the alternative hypothesis, we test if this proportion is greater than 84%, that is:

[tex]H_1: p > 0.84[/tex]

Item 2:

It would mean that at most 84% of teenagers think highly of their mother, as we could not conclude that the proportion is more than 84%.

Item 3:

135/150 = 0.9.

We are working with a right-tailed test, hence it means that there is a 0.0225 = 2.25% probability that at least 0.9 = 90% of teenagers think highly of their mother.

Item 4:

The p-value is of 0.0225, which is less than the significance level of 0.05, which means that we would reject the null hypothesis.

Compound interest

Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.

The amount after 4 years is calculate by following formula;

[tex]\rm V(t)= P(1+\dfrac{r}{n})^{nt}[/tex]

Where t = years since initial deposit n = number of times compounded per year r = annual interest rate (as a decimal) P = initial (principal) investment V(t) = value of investment after t years.

Substitute all the values in the formula;

[tex]\rm V(t)=6,000\times (1+\dfrac{0.015}{12})^{12\times 4}\\\\V(t)=6,370.78[/tex]

Answer:

1. y = 3x - 5

2. y = -4x + 2

3. y = -3x - 4

4. y = -3x - 6

Step-by-step explanation:

These questions are pretty easy. The only thing you have to do, to turn the equation into slope intercept form, is to solve for y in each equation

All the equations are in standard form, and we need to rewrite them in slope intercept form, so here are the steps

For the first equation: -3y + 9x = 15

We solve for y in the equation

-3y + 9x = 15

1. Subtract 9x from each side to isolate y

-3y + 9x - 9x = 15 - 9x

2. Simplify

-3y = 15 - 9x

3. Divide each term by -3 to get y by itself.

-3y/-3 = 15/-3 -9x/-3

4. Simplify

y = 3x - 5

For the second equation, we do the same proces, we just solve for y
−4x − y + 2 = 0

Step 1: Add 4x to both sides.

−4x − y + 2 + 4x = 0 + 4x

−y + 2 = 4x

Step 2: Subtract 2 to both sides.

−y + 2 − 2 = 4x − 2

−y = 4x − 2

Step 3: Divide both sides by -1

-y/-1 = 4x/-1 -2/-1

y = -4x + 2

For the third equation, we do the same thing too

2y + 6x = -8

Step 1: Subtract 6x to both sides.

6x + 2y − 6x = −8 − 6x

Switch -8 and -6x

2y = −6x − 8

Step 2: Divide both sides by 2.

2y/2 = -6x/2 -8/2

y = -3x - 4

And for the last equation, we do the same thing we did in the second equation

-6 - 3x - y = 0

Step 1: Add 3x to both sides.

−3x − y − 6 + 3x = 0 + 3x

−y − 6 = 3x

Step 2: Add 6 to both sides.

−y − 6 + 6 = 3x + 6

−y = 3x + 6

Step 3: Divide both sides by -1.

-y/-1 = 3x/-1 + 6/-1

y = -3x - 6

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given to us

30 points for fish

80 points for Octopus

-15 points for crab

As it is given in the problem that Mona catches x number of fishes, y number of octopuses, and z number of cabs. therefore,

Points earned through fishes [tex]=x \times 30 = 30 x[/tex]

Points earned through Octopus [tex]=y \times 80 = 80 y[/tex]

Points earned through crabs[tex]=z \times -15= -15 z[/tex]

Total points earned by Mona in the video game

= Points earned through fishes, octopus, and crabs

You can do that by following these steps:

Multiply the outside number by the number in the denominator

Add the product to the number in the numerator

5[tex]\frac{1}{4}[/tex] = [tex]\frac{21}{4}[/tex]

3[tex]\frac{7}{8}[/tex] = [tex]\frac{31}{8}[/tex]

Now, convert these fractions so that they share the same denominator. 4 and 8 share the same factor of 8. Multiply the numerator and denominator of [tex]\frac{21}{4}[/tex] by 2 so that the denominator becomes 8.

[tex]\frac{21}{4}[/tex] = [tex]\frac{42}{8}[/tex]

Now find how many inches of string each person has by using multiplication:

Cooper has [tex]\frac{31}{8}[/tex] × 4 = [tex]\frac{124}{8}[/tex] inches total

To find how much more inches Sophie has, subtract the two fraction from each other:

Answers

Answer:

a) 4 cm

b) 5 cm

Step-by-step explanation:

a) Area of a rectangle = width x length

From inspection, the width of this rectangle is 2 cm and the length is 8 cm

area of the rectangle = 2 x 8 = 16 cm²

A square has 4 sides of equal measure.

Let the side of a square = [tex]x[/tex]

Therefore, the area of a square = [tex]x \times x = x^2[/tex]

If the square has the same area as the rectangle, then

[tex]x^2=16[/tex]

Square root both sides:  [tex]x = \sqrt{16} =\pm4[/tex]

Since the length of a side cannot be negative, [tex]x=4[/tex] only

So the side length of the square = 4 cm

b) Perimeter of a rectangle = 2 x length + 2 x width

⇒ perimeter of the rectangle = (2 x 8) + (2 x 2) = 20 cm

Since the side lengths of a square are equal, and a side length = [tex]x[/tex]

Perimeter of a square = 4 x [tex]x[/tex] = 4[tex]x[/tex]

If a square has the same perimeter as the rectangle, then

[tex]4x=20[/tex]

Divide both sides by 4:  [tex]x=20 \div 4 = 5[/tex]

side length of this square = 5 cm

Answer:

a)4cm  b)5cm

Step-by-step explanation:

a)

[tex]Solution,\\\\Length(l)=8cm\\\\Breadth(b)=2cm\\\\Now,\\\\Area=l*b\\\\Area=8cm*2cm\\\\Area=16cm^{2}[/tex]

Area of the rectangle is 16cm².

When,

Area of the rectangle is equal to the area of the square then,

Area of square=16cm²

Now,

→Length=√Area

→Length=√16cm²

→Length=4cm


b)

[tex]Solution,\\\\Length(l)=8cm\\\\Breadth(b)=2cm\\\\Now,\\\\Perimeter=2(l+b)\\\\Perimeter=2(8cm+2cm)\\\\Perimeter=2(10cm)\\\\Perimeter=20cm[/tex]

The perimeter of rectangle=20cm

When,

The perimeter of the rectangle is equal to the perimeter of the square then,

The perimeter of square=20cm

Now,

Length=Perimeter/4

Length=20cm/4

Length=5cm
