In this question, we're looking for the number Malcom used to scale the two numbers. We can see there's a pattern, 9 is 1/6 of 54 and 40 is 1/6 of 240!

(54 divided by 9 is 6 and 240 divided by 40 is 6!)

therefore, the scale factor must be 6

Answer:

842 grams

Step-by-step explanation:

[tex]70\frac{1}{6} =\frac{421}{6}[/tex]

[tex]\frac{421}{6} *12\\\\842[/tex]

One cake consists of 421/6 grams of chocolate.

Since Sally wants to give 1 cake to 12 friends, we multiply 421/6 and 12.

To make 12 cakes, she needs 842 grams of chocolate.

Answer:

  cos(x -π/3) = (1/2)cos(x) +(√3/2)sin(x)

Step-by-step explanation:

You want cos(x -π/3) written in terms of sine and cosine.

The formula for the cosine of the difference between two angles is ...

  cos(a -b) = cos(a)cos(b) +sin(a)sin(b)

We have a=x, b=π/3, so the desired function is ...

  cos(x -π/3) = cos(x)cos(π/3) +sin(x)sin(π/3)

We know that ...

so the rewrite is ...

  cos(x -π/3) = (1/2)cos(x) +(√3/2)sin(x)

Answer:

The 90% confidence interval for (u1 - u2) is the range from; ( 0.50 - 2.06 )

Step-by-step explanation:

Given the data in the question;  

Adult with No children under 18                    Adult with children under 18

x"₁ = 5.65                                                             x"₂ = 4.37

s₁ = 2.43                                                               s₂ = 1.73

n₁ = 40                                                                  n₂ = 40

with 90% confidence

significance level ∝ = 1 - 90% = 1 - 0.9 = 0.1    

Degree of freedom df = 39

Now, since variance are not equal and are also unknown, we will use 2 sample t-distribution method;

Standard Error: σx"₁ - x"₂ = [tex]\sqrt{\frac{s_1^2}{n_1} + \frac{s_2^2}{n_2} }[/tex]

Critical value = [tex]t_{\alpha /2, df[/tex] = [tex]t_{0.05, df=39[/tex] = 1.645   { from standard normal table }

Now,

Margin of Error = E = [tex]t_{\alpha /2, df[/tex] × [tex]\sqrt{\frac{s_1^2}{n_1} + \frac{s_2^2}{n_2} }[/tex]

we substitute

E = 1.645 × [tex]\sqrt{\frac{2.43^2}{40} + \frac{1.73^2}{40} }[/tex]      

E = 1.645  × √( 0.1476225 + 0.0748225 )

E = 0.7758478

Now, our point difference will be; x"₁ - x"₂ = 5.65 - 4.37 = 1.28

So Limit at 90% confidence interval will be;

x"₁ - x"₂ ±  E

Lower Limit = x"₁ - x"₂ - E = 1.28 - 0.7758478 = 0.50415 ≈ 0.50

Upper Limit = x"₁ - x"₂ + E = 1.28 + 0.7758478 = 2.05584 ≈ 2.06

Therefore, The 90% confidence interval for (u1 - u2) is the range from; ( 0.50 - 2.06 )

Answer:

To calculate the percent of change for your grade, you will need to know your original grade and your revised grade. If you originally got 5 questions right and you checked your work and ended up with 15 questions right, you can calculate the percent of change as follows:

Subtract your original score from your revised score to find the difference: 15 - 5 = 10

Divide the difference by your original score and multiply by 100 to express the change as a percentage: (10 / 5) x 100 = 200%

This means that your grade increased by 200%.

The amount of money that can be saved per ounce by guiding the larger box is $0.009.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis of the given problem.

Given is that a 38 ounce box of cat food costs $1.69 and a 24 ounce box costs $1.29.

For the larger box -

38 ounce box of cat food costs $1.69

1 ounce of this box will cost $(1.69/38) = $0.045

For the smaller box -

24 ounce box of cat food costs $1.29

1 ounce of this box will cost $(1.29/24) = $0.054

Money that can be saved per ounce by guiding the larger box -

0.054 - 0.045

0.009

Therefore, the amount of money that can be saved per ounce by guiding the larger box is $0.009.

Step-by-step explanation:

According to question as both side are equal so it is an isosceles triangle and the value of X is 18.

An isosceles triangle is a triangle with two sides of equal length. Some properties of an isosceles triangle include:

so In this triangle ,

The mid point on horizontal side is given and 5m line cut the mid point of both the sides.

both side are equal as it is an isosceles triangle.

and given in the question,

side/2 =9

and  one side is equal to x.

and both sides are equal,

therefore

side = 9*2 = 18

so the value of x = 18.
