Emily made blueberry muffins for her scout troop's bake sale. For her first batch, she used 1 cup of blueberries and 2 cups of oats. She didn't think that would make enough muffins, so she made a larger second batch with 3 cups of blueberries and 6 cups of oats. When she took the last tray out of the oven, her little brother asked if he could have a muffin with lots of blueberries as a snack. Which batch had a greater ratio of blueberries to oats? The first batch had the greater ratio. The second batch had the greater ratio. Neither. The batches had the same ratio.

Answer:

Step-by-step explanation:

x + y = 6 -------------(I)

    y = 6 -x

2.5x + 3.25y = 15.75 -------------(II)

substitute y = 6 - x in equation (II)

2.5x + 3.25*(6 - x) = 15.75      {Distributive property: a(b +c) =a*b + b*c}

2.5x + 3.25*6 - x * 3.25 = 15.75    

2.5x + 19.5 - 3.25x = 15.75

2.5x - 3.25x + 19.5 = 15.75    {Combine like terms}

-0.75x +  19.5 = 15.75

            -0.75x=15.75 - 19.5

           -0.75x = -3.75

                  x = -3.75/-0.75

                  x = 5

Plugin x = 5 in (I)

5 + y = 6

     y = 6 - 5

    y = 1

Answer:

$ 2,200 for 8%, $ 1,300 for 12%

Step-by-step explanation:

I=PRT

Let Bank 1 be x

332= x (8%) + (3,500-x) 12%

332= x (0.08) + (3,500-x) 0.12   change the percent to decimal

332= 0.08x + 420 - 0.12x

0.04x= 420-332

x= [tex]\frac{88}{0.04}[/tex]

x= 2,200 (Bank 1)

Bank 2= 3,500-Bank 1

Bank 2= 3,500- 2,200

Bank 2= 1,300

Answer:

Step-by-step explanation:

6/9+x=7/10

x=7/10-6/9

when adding fractions both denominators must be equal, we’ll make them 90

x=(7/10)(9/9)-(6/9)(10/10)

x=63/90-60/90

x=3/90, the greatest divisor of 3 and 90 is 3 so divide both the numerator and denominator by 3

x=(3/3)/(90/3)

x=1/30

Answer:

14 / 12 miles or 1 1/6 miles

Step-by-step explanation:

A group of campers walked 4 2/3 miles along a hiking trail.

Distance = 4 2/3 miles

Another group of campers walked 1/4 of that distance with the first group before turning off onto another trail.

That is; 1/4 of 4 2/3 miles

How many miles did the two groups of campers walk with one another ?

This is obtained by solving 1/4 of 4 2/3 miles

Converting 4 2/3 to an improper fraction;

4 2/3 = 14 / 3 Miles

1/4 of 14 / 3

1 / 4 * 14 / 3

= 14 / 12 miles or 1 1/6 miles

This may be more complicated than it looks but here are the odd numbers before nine:

1, 3, 5, 7

Answer:

$30.40

Step-by-step explanation:

to find out how much 20 candy bars would cost, first, we have to find out how much 1 candy bar costs. we do this by dividing $19.76 by 13.

$19.76 ÷ 13 = $1.52

so now we know that one candy bar costs $1.52. now, we multiply this value to 20, to know how much 20 candy bars cost. therefore, we get:

20 × $1.52 = $30.40

Answer:

a.) X  ≈ N (0, 12)

b.) Y ≈  exp(2)

c.) The given distribution is not defined.

d.) Not a standard form of any distribution .

Step-by-step explanation:

Given - In parts (a)−(d) below, either use the information given to determine

            the distribution of the random variable, or show that the information

            given is not sufficient by describing at least two different random

            variables that satisfy the given condition.

To find - (a) X is a random variable such that Mₓ(t) = [tex]e^{6t^{2} }[/tex] when |t| < 2.

              (b) Y is a random variable such that  [tex]M_{Y}[/tex](t) = [tex]\frac{2}{2 - t}[/tex] for t < 0.5.

              (c) Z is a random variable such that [tex]M_{Z}[/tex](t) = ∞ for t ≥ 5.

              (d) W is a random variable such that [tex]M_{W}[/tex](2) = 2

Proof -

a.)

As we know that the moment generating function of normal distribution is given by

Mₓ(t) = [tex]e^{ut + \frac{1}{2}t^{2} \sigma^{2}}[/tex]

Now,

Mₓ(t) = [tex]e^{6t^{2} }[/tex]

       = [tex]e^{0(t) + \frac{12}{2} t^{2} }[/tex]

⇒μ = 0, σ = 12

Nd it is represented by

X  ≈ N (0, 12)

b.)

Moment generating function of exponential function is given by

[tex]M_{Y}[/tex](t) = [tex]( 1 - \frac{t}{\theta})^{-1}[/tex]

Now,

 [tex]M_{Y}[/tex](t) = [tex]\frac{2}{2 - t}[/tex] for t < 0.5.

          = [tex]\frac{1}{\frac{2 - t}{2} }[/tex]

          = [tex]\frac{1}{1 - \frac{t}{2} }[/tex]

          = [tex]( 1 - \frac{t}{2} )^{-1}[/tex]

And it is represented by

Y ≈  exp(2)

c.)

Z is a random variable such that [tex]M_{Z}[/tex](t) = ∞ for t ≥ 5.

The given distribution is undefined.

d.)

[tex]M_{W}[/tex](2) = E([tex]e^{2w}[/tex] )

           = [tex]\int\limits^{-\infty}_{\infty} {e^{2w} f(w) } \, dw[/tex]

          = 2

It is not the standard form of any distribution.

Answer:

Step-by-step explanation:

Make sure the denominators are the same.

Subtract the numerators. Put the answer over the same denominator.

Simplify the fraction (if needed).

Answer:

1 < a < b < 4

Answer:

16 percent

Step-by-step explanation:

75 is the old value and 87 is the new value. In this case we have a positive change (increase) of 16 percent because the new value is greater than the old value.

The answer is 1/5^12.

Multiply the -6 by 2 to get 5^-12. Then, to make the exponent positive, move it to the denominator to get your answer, 1 over 5^12.
