For 100​ births, P(exactly 55 ​girls)equals0.0485 and ​P(55 or more ​girls)equals0.184. Is 55 girls in 100 births a significantly high number of​ girls? Which probability is relevant to answering that​ question? Consider a number of girls to be significantly high if the appropriate probability is 0.05 or less

Answers

Answer: 55 can not be considered a significantly high number of girls.

The probability is relevant to answering that​ question = \text{P(55 or more girls)}=0.184.

Step-by-step explanation:

Given : For 100​ births, \text{P(exactly 55 girls)}=0.0485

and \text{P(55 or more girls)}=0.184.

Also it is said that consider a number of girls to be significantly high if the appropriate probability is 0.05 or less

To check :- If 55 girls in 100 births a significantly high number of​ girls .

We can see that \text{P(exactly 55 girls)}=0.0485<0.05

and \text{P(55 or more girls)}=0.184>0.05 , it means it is likely to occur 55 or more girls .

So 55 can not be considered a significantly high number of girls.

What value of x will make 2x-6=3x+1-x-7 true?

Answers

2x-6=3x=3x+1-x-7

2x-6=2x+8
2x-6-2x+6=2x-2x+8+6
0=0+14
No Solution



Hi there

2x - 6 = 3x + 1 - x - 7
First we need to combine like terms
2x - 6 = (3x - x) + (1 - 7)
2x - 6 = 2x - 6
2x - 2x = -6 + 6
0 = 0

IF i = √-1 , then the expression is equal to (42 + 21i) or 21(2 + i) .

The sum of two numbers is 30 and their difference is 2.  Find the two numbers by writing and solving asystem of equations

Answers

The numbers are 14 & 16.

The equations you need to solve are:

x + y = 30
x - y = 2  ==>  (redefine in terms of y)  y = x - 2

substitute into first equation

x + x - 2 = 30
2x = 30 + 2
x = 32/2 = 16

16 + y = 30
30 - 16 = y = 14

x = 16
y = 14

And that's how that is done.

The correct answer is:

The numbers are 14 and 16.

Explanation:

Let x and y represent the numbers. Since the sum of the numbers is 30, this gives us the equation

x+y = 30.

Since the difference of the numbers is 2, this gives us the equation

x-y = 2.

This gives us the system

\left \{ {{x+y=30} \atop {x-y=2}} \right.

To solve this, we will eliminate one variable. Since the coefficients are all the same, but the y-variables have different signs, we will eliminate them by adding the equations together:

Divide both sides by 2:

2x/2 = 32/2

x = 16.

Substitute this back into our first equation:

16+y=30

Subtract 16 from each side:

16+y-16=30-16

y=14

tan ⊖ + cot ⊖ = 1/sin⊖cos⊖

Answers

tan ⊖ + cot ⊖ = 1/sin⊖cos⊖

sin ⊖ / cos ⊖  + cos ⊖/sin ⊖ = 1/sin⊖cos⊖

(sin ⊖*sin ⊖  + cos ⊖*cos ⊖)/sin⊖cos⊖ = 1/sin⊖cos⊖

[(sin ⊖)^2 + (cos ⊖)^2 ] /sin⊖cos⊖ = 1/sin⊖cos⊖
