Answer:

14.1 ft³ (to 3 s.f.)

Step-by-step explanation:

\boxed{volume \: of \: sphere =  \frac{4}{3}π{r}^{3} }

Given that the radius is 1.5 feet, substitute r= 1.5 into the formula above:

Volume of sphere

=  \frac{4}{3} (π)( {1.5}^{3} ) \\  = 14.1 \: ft^{3}

(to 3 s.f.)

a carnival game consists of 3 dart throws at a target. The probability of scoring a hit on any one throw is 30%. Using the binom
Ghella [55]

Answer:  Probability of scoring 2 hits = 0.63.

Step-by-step explanation:

Since we have given that

Number of dart throws at a target = 3

Probability of scoring a hit on any one throw = 30%

We will use "Binomial Distribution" i.e.

P=^nC_rp^r(1-p)^{n-r}

where,

n denotes number of dart throws at a target,

r denotes number of required throws

p denotes probability of success

(1-p) denotes probability of failure

So, Probability of success is given by

\frac{30}{100}=\frac{3}{10}

Probability of failure is given by

1-\frac{30}{100}=\frac{70}{100}=\frac{7}{10}

We will use "Binomial Distribution" i.e.

P(X=2)=^3C_2(\frac{3}{10})^2\times (\frac{7}{10})\\\\P(X=2)=\frac{9}{100}\times \frac{7}{100}\\\\P(X=2)=\frac{63}{100}\\\\P(X=2)=0.63

Hence, Probability of scoring 2 hits = 0.63.

abruzzese [7]
36% of 80

First, you multiply 36 and 80.

36*80 = 2880

Now, we divide that by 100.

2880/100 = 28.8

Our final answer: 28.8
