Answer: <em>the length of each edge is 0.5 ft.</em>

Step-by-step explanation:

$V=S^{3}\\\\S=\sqrt[3]{V}=\sqrt[3]{\dfrac{1}{8}} = \sqrt[3]{\bigg ( \dfrac{1}{2} \bigg)^{3} } = \dfrac{1}{2}=0.5 \: \: \: (ft)$

Question number 29 you work in the shipping department of an organic food company and need to calculate the net weight of a jar

umka2103 [35]

The net weight of a jar of raspberry preserves will be 4.45 ounces.

The volume of the cylinder can be calculated as the product of the base of the cylinder and the height of cylinder.

The volume of cylinder= base of cylinder * height of the cylinder

⇒ volume of cylinder = πd²*h/4

Here, given that

the inside diameter of the cylinder is 1.5 inches.

d= 1.5 inches

the inside height of the cylinder is 4.75 inches.

h= 4.75 inches

putting these above values for calculating the volume of the cylinder

Volume =V = πd²*h/4

⇒ V= π*(1.5)²*4.75/4

⇒V = 8.40 cube inches

Given that the raspberry preserve weighs 0.53 ounces per one cubic.

for one cubic the weight is 0.53 ounces

for 8.40 cubic the weight will be 8.40*0.53= 4.45 ounces

Therefore The net weight of a jar of raspberry preserves will be 4.45 ounces.

Hope Amelia Solo, the American soccer goalkeeper, World Cup champion and two-time Olympic gold medalist, allows goals at a rate

Nuetrik [128]

Answer:

3.70% probability she allows more than one goal

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given time interval.

X~Pois(0.3)

This means that $\mu = 0.3$

In her next match, what is the probability she allows more than one goal?

Either she allows at most one goal, or she allows more than one goal. The sum of the probabilities of these events is decimal 1. So

$P(X \leq 1) + P(X > 1) = 1$

We want $P(X > 1)$ . So

$P(X > 1) = 1 - P(X \leq 1)$

In which

$P(X \leq 1) = P(X = 0) + P(X = 1)$

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 0) = \frac{e^{-0.3}*(0.3)^{0}}{(0)!} = 0.7408$

$P(X = 1) = \frac{e^{-0.3}*(0.3)^{1}}{(1)!} = 0.2222$

$P(X \leq 1) = P(X = 0) + P(X = 1) = 0.7408 + 0.2222 = 0.9630$

$P(X > 1) = 1 - P(X \leq 1) = 1 - 0.9630 = 0.0370$

3.70% probability she allows more than one goal
