If there are 6 serving in a 2/3 pound lb package of pound is in each serving

Serhud [2]

Answer:

$\boxed{\math{\frac{1}{9}\text{ lb}}}$

Step-by-step explanation:

$\text{Size of one serving} = \dfrac{\text{Total size}}{\text{No of servings}} = \dfrac{\frac{2}{3}\text{ lb}}{\text{6 servings}}\\\\\text{Change the 6 to a fraction and change divide to multiply}\\\\\dfrac{2}{3} \div 6 = \dfrac{2}{3} \times \dfrac{1}{6}$

$\text{Cancel the 2s}\\\\\dfrac{2}{3} \times \dfrac{1}{6} = \dfrac{1}{3} \times \dfrac{1}{3}\\\\\text{Multiply numerators and denominators}\\\\\dfrac{1}{3} \times \dfrac{1}{3} = \dfrac{1}{9}\\\\\text{Each serving contains }\boxed{\mathbf{\frac{1}{9}\textbf{ lb}}}$

A kite was broken into two triangles.

Mekhanik [1.2K]

<h2>Answer:</h2><h2>Area of the kite = 80 $cm^{2}$ , Area of traingle = 40 $cm^{2}$ and height of the triangle, h = 5 cm</h2>

Step-by-step explanation:

A kite is broken into two triangles

Given the base of the traingle, b = 16 cm

Height of the triangle, h = 5 cm

Area of traingle = $\frac{1}{2} (b.h)$

= $\frac{1}{2} (16) (5)$

= 40 $cm^{2}$

Area of the kite = area of triangle 1 + area of triangle 2

= 40 + 40

= 80 $cm^{2}$

At a Noodles & Company restaurant, the probability that a customer will order a nonalcoholic beverage is .56. a. Find the pr

Sergio [31]

Answer:

a. 0.0000

b. 0.9949

c. 0.0212

d. 1.0000

Step-by-step explanation:

a. This is a binomial probability distribution problem of the form:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}$

#Given n=15, p=0.56, the probability of none will order a non-alcoholic drink:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\\\P(X=0)={15\choose 0}0.56^0(1-0.56)^{15}\\\\\\=0.0000045$

$\approx 0.0000$

Hence, the probability that none will order a non-alcoholic drink is 0.0000

b. The probability that at least 4 will order a non-alcoholic drink is:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X\geq 4)=1-P(X$

Hence, the probability of at least 4 non-alcoholic orders is 0.9949

c. The Probability that fewer than 5 orders will be made is calculated as:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X$

Hence, the probability of less than 5 orders is 0.0212

d. The probability of all orders being non-alcoholic is equivalent to 1 minus no order being non-alcoholic.

-From a above, the probability of zero non-alcoholic order is , P(X=0)=0000045

-Therefore:

$P(All)=1-P(none)\\\\=1-0.0000045\\\\=0.999996$

$\approx 1.0000$

Hence, the probability that all orders are non-alcoholic 1.0000
