An animal park has lions, tigers and zebras. 20% of the animals are lions and half of the animals are zebras. If there are 120 a

RoseWind [281]

Answer:

$36\ tigers$

Step-by-step explanation:

Let

x ----> the number of lions

y ----> the number f tigers

z ----> the number of zebras

we know that

$x+y+z=120$ ----> equation A

Remember that

$20\%=20/100=0.20$

$50\%=50/100=0.50$

To find out the number of lions, multiply the total animals by the percentage of lions

$x=0.20(120)=24\ lions$

To find out the number of zebras, multiply the total animals by the percentage of zebras

$z=0.50(120)=60\ zebras$

Substitute the value of x and the value of z in equation A and solve for y

$24+y+60=120$

$y+84=120$

$y=36\ tigers$

Answer:

B ) 0.25 + 0.75 + 0.76 + 0.24

Step-by-step explanation:

commutative law of addition:-

According to the commutative property of addition,changing the order of the numbers.we are adding doesn't change the sum.

let a,b,c+d are two numbers

The commutative property condition in addition a+b+c+d = a+c+b+d

Given expression 0.25+0.76+0.75+0.24 = 0.25 + 0.75 + 0.76 + 0.24

conclusion:- Answer B.

MariettaO [177]

Answer:

The probability that Isaiah will make both penalty kicks is 25%.

Step-by-step explanation:

We are given that Isaiah scores with 50% of his penalty kicks in soccer.

He flips two fair coins to conduct a simulation with 20 trials to determine the likelihood that he will make his next two penalty kicks.

The above situation can be represented through binomial distribution;

$P(X =r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r};x=0,1,2,3,......$

where, n = number of trials (samples) taken = 2 penalty kicks

r = number of success = make both penalty kicks

p = probability of success which in our question is probability

that Isaiah scores with his penalty kicks, i.e; p = 50%

Let X = Number of penalty kicks made by Isaiah

So, X ~ Binom(n = 2 , p = 0.50)

Now, Probability that Isaiah will make both penalty kicks is given by = P(X = 2)

P(X = 2) = $\binom{2}{2} \times 0.50^{2} \times (1-0.50)^{2-2}$

= $1 \times 0.50^{2} \times 0.50^{0}$

= 0.25 or 25%

Hence, the probability that Isaiah will make both penalty kicks is 25%.
