Answer:

The probability that 24 or more from this sample will be female is 0.2643.

Step-by-step explanation:

Define X as the number of female students.

The random variable X follows a Binomial distribution with parameters n = 40 and p = 0.55.

But the sample selected is too large and the probability of success is close to 0.50.

So a Normal approximation to binomial can be applied to approximate the distribution of X if the following conditions are satisfied:

1. np ≥ 10

2. n(1 - p) ≥ 10

Check the conditions as follows:

[tex]np=40\times 0.55=22>10\\\\n(1-p)=40\times (1-0.55)18>10[/tex]

Thus, a Normal approximation to binomial can be applied.

So,  X follows normal distribution with mean and standard deviation:

[tex]\mu=np=40\times 0.55=22\\\\\sigma=\sqrt{np(1-p)}=\sqrt{40\times 0.55\times (1-0.55)}=3.15[/tex]

Compute the probability that 24 or more from this sample will be female as follows:

[tex]P(X\geq 24)=P(\frac{X-\mu}{\sigma}>\frac{24-22}{3.15})\\\\=P(Z>0.63)\\\\=1-P(Z<0.63)\\\\=1-0.7357\\\\=0.2643[/tex]

Thus, the probability that 24 or more from this sample will be female is 0.2643.

Answer:

y=mx+b

Step-by-step explanation:

The required linear equation is the slope intercept form of a linear equation given by y = mx + b.

What is the linear equation with two variables ?

A linear equation with two variables is any equation that can be expressed in form ax + by + c = 0, where a, b, and c are all real values.

We know that there are various ways of representing a linear equation as follows :

These are all legitimate variations of linear functions, and they may all be transformed into and out of other linear functions.

The linear equation in two variables x and y is an equation that can be written in the form y = mx + b , where m and b are constants.

Therefore, the required linear equation is the slope intercept form of a linear equation given by y = mx + b.

Answer:

There are 16 bowls

Step-by-step explanation:

Number of bowls = x

Total grapes added = 12 x 8 = 96

The average increased by 6

So 96/6 = 16

There were 16 bowls of grapes on the table

OR

12 x 8 = 96

96/6=16

Answer:

11355mL

Step-by-step explanation:

It gives you how many milliliters are in one gallon. From there it gives extra information that isn't needed so you skip it and go to the question which is the amount of mL in 3 gallons. So you take the amount from the first sentence (3,785 mL) and multiply it by the amount that they ask in th equestion (3 gal) .

3785*3= 11355

Step-by-step explanation:

Answer:

54x

Step-by-step explanation:

The equation y = 45 models the saving.

If m is the slope of the line that passes through the point (x₁, y₁), then the equation of the line is y - y₁ = m (x - x₁).

Given the graph of the equation.

Note that the graph passes through points (0,0) and (2,90).

The slope of the line is:

m = (90 - 0)/(2 - 0)

m = 45

The equation of the line with a slope of m = 45 and passes through (0,0) is:

y -0 = 45(x - 0)

y = 45x

Hence, the equation y = 45 models the saving.

Answer:

C

Step-by-step explanation:

Using the Pythagorean theorem, find BA: [tex]\sqrt{37^{2}+53^{2} } = \sqrt{4178}[/tex]

Making BC = x, find the lenth of BD: [tex]\sqrt{x^{2} +37^{2} }[/tex]

Since DBA is a right triangle, this follows: [tex]DA^{2}=BD^{2}+BA^{2}[/tex]

Substitute: [tex](x+53)^{2} =\sqrt{4178} ^{2} +\sqrt{x^2+37^2} ^{2}[/tex]

Expand: [tex]x^{2} +106x+2809=x^{2} +5547[/tex]

Solve: 106x = 2736

Finally: x ≈ 25.8 ≈ 26

Therefore: C

Answer:

[tex]M_{2}=\frac{F_{g}r^{2}}{GM_{1}}[/tex]

Step-by-step explanation:

To find [tex]M_{2}[/tex], you can manipulate the formula.

[tex]F_{g}=\frac{GM_{1}M_{2}}{r^{2}}[/tex] (given)

[tex]F_{g}r^{2}=GM_{1}M_{2}[/tex]  (times r² on both sides)

[tex]M_{2} = \frac{F_{g}r^{2}}{GM_{1}}[/tex]  (divide both sides by [tex]GM_{1}[/tex])

∴ [tex]M_{2}=\frac{F_{g}r^{2}}{GM_{1}}[/tex] in terms of [tex]F_{g}, G, M_{1}[/tex] and [tex]r[/tex]

The square root of 8 in radical form is represented as √8 which is also equal to 2√2 and as a fraction, it is equal to 2.828 approximately. Squares root of a number is the number, which, on multiplying by itself gives the original number. Since 8 is not a perfect square, hence the value is represented in root form.

Answer:

m=n+5

Step-by-step explanation:

You just add n on both sides to get m because m is isolated on one side and variables and numbers on the other side of the equal sign.

Answer:

m=n+5

Step-by-step explanation:

m-n=5

add n on both sides

m=n+5

Answer:

y=5.79x
