The probability that a newborn baby at the hospital is female is 50%. What is the probability that at least 2 babies of 3 childr

Readme [11.4K]

Answer:

0.25 is the probability

Step-by-step explanation:

In this question, we are tasked with calculating the probability that in a hospital on a certain day, at least 2 out of three babies born that day are female.

To calculate the probability , let’s list out some needed facts;

Let the probability of having a baby girl be g = 50% = 50/100 = 1/2 = 0.5

The probability of having a boy b will be 1-g = 1-0.5 = 0.5

Now, we have 3 babies and we want to find the probability of at lest two being girl.

Mathematically that would be ; ggb or ggg

since we are having at lest 2 girls

For the ggb, we have ; 0.5 * 0.5 * 0.5 = 0.125

For the ggg we have 0.5 * 0.5 * 0.5 = 0.125

In probability, once we have or, we add.

Thus 0.125 + 0.125 = 0.25

Answer:

120 different meals.

Step-by-step explanation:

Start with the entrees: There are 4

There are side dishes : 4

Drinks: 5

The side dishes can be 4!/(2!2!) (order does not matter here). There are 6 ways.

The entrees are 1 of 4: 4

And 5 drinks

P(dinner) = 5 * 4 * 6 = 120

Solve the radical equation. square root 6n-11= n – 3 Which solution is extraneous? A.)2

Anvisha [2.4K]

ANSWER

D) 10

EXPLANATION

We want to solve the radical equation,

$\sqrt{6n - 11} = n - 3$

Square both sides,

$6n - 11 = (n - 3) ^{2}$

Expand brackets on right hand side,

$6n - 11 = {n}^{2} - 6n + 9$

Rewrite in general quadratic equation form,

${n}^{2} - 12n + 20 = 0$

Factor to obtain,

$(n - 2)(n - 10) = 0$

Apply the zero product principle to get,

$n = 2 \: or \: n = 10$

We put n=2 into the equation to get,

$\sqrt{6(2) - 11} = 2 - 3$

$1 = - 1$

This statement is false, hence 2 is an extraneous solution

We put n=10, to get

$\sqrt{6(10) - 11} = 10 - 3$

$\sqrt{49} = 7$

$7 = 7$

This is true, hence the only solution is
$n = 10$

A store sells a 3-pound bag of oranges for $3.60 and a 5-pound bag of oranges for $5.25. What is the difference between the pric

tigry1 [53]

The difference between the price per pound for the three pound bag of oranges and the price per pound for the 5 lb bag of oranges is $0.15

Given

Price of 3lb bag = $3.60

Price of 5lb bag = $5.25

We have to calculate the per pound price for each bag to compare the per pound price for both

Price of one pound in 3lb bag-

$\frac{3.60}{3}=$1.20$

Price of one pound in 5lb bag-

$\frac{5.25}{5} = 1.05$

Difference between the prices-

$1.20-1.05= 0.15$

The difference between the price per pound for the three pound bag of oranges and the price per pound for the 5 lb bag of oranges is $0.15
