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:

[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]

Answer:

16 pints

Step-by-step explanation:

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:

y=5.79x

Step-by-step explanation:

What you'll first do it divide both sides by y

So, y/y =5.79x/y

so the answer for question 1 is going to be 5.79xy.

If this is from the textbook, use slader. it might help you better than me.

Now do the same thing for the second one.

Be safe guys!:)

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:

x=-5

Step-by-step explanation:

Divide by 5 on both sides and you get x=-5

Hope this helps mark brainliest if correct

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

THE NUMBER BEHIDE THE DECIMAL IS over.500

Answer:

1/4

Step-by-step explanation:

1/3 divided by 4/3. To divide, flip the fraction on the right.

1/3*3/4. Now you can divide both sides by 3.

1/1*1/4. 1x1/4 which is 1/4

1/4.

Hope this helps :D Please mark brainliest

Hello! c: if you need to write and explain your answer use this because its not a sample response i hope you get an A!

To find the quotient you must first, Find the reciprocal of the divisor and multiply the dividend by the divisors reciprocal.

In this case the answer would be 1/4.

Answer:

area=47cm²

Step-by-step explanation:

Answer:

A.

Step-by-step explanation:

Since the associate property is grouping and since the only that groups the number differently is A.

6(1/3 x 7/5) changes to (6 x 1/3) 7/5

Hope this helps :)

Answer:

The cost of grapefruits per box is $3, The cost of strawberries per box is $2.5

The cost of avocados per box is $6

Step-by-step explanation:

Let us represent the price of Grapefruits per box = g

Strawberries per box = s

Avocados per box = a

Alyssa buys two boxes of strawberries and three boxes of avocados and spent $23

2s + 3a = 23 ....... Equation 1

a = 23 - 2s

London buys three boxes of grapefruit and four boxes of strawberries in Spain $19

3g + 4s = 19 ....... Equation 2

Tina buys seven boxes of grapefruit and five boxes of avocados in Spencer $51

7g + 5a = 51..... Equation 3

2s + 3a = 23 ....... Equation 1

3g + 4s = 19 ....... Equation 2

7g + 5a = 51..... Equation 3

Substituting 3a = 23 - 2s in Equation 3

a = 23 - 2s/3

7g + 5(23 - 2s/3) = 51

7g +( 115 - 10s/3) = 51

Multiply through by 3

7g × 3 + ( 115 - 10s/3) × 3 = 51 × 3

21g + 115 - 10s = 153

21g -10s = 38 ........ Equation 4

Combining Equation 2 and 4

3g + 4s = 19 ....... Equation 2 × 10

21g -10s = 38 ........ Equation 4 × 4

30 + 40s = 190.. Equation 5

84g - 40s = 152 .... Equation 6

We Add Equation 5 and Equation 6 to eliminate s

114g = 342

g = 342/114

g = $3

To find s, cost 0f straw berries

g = $3

3g + 4s = 19 ....... Equation 2

3(3) + 4s = 19

9 + 4s = 19

4s = 19 -9

4s = 10

s = 10/4

s = $2.5

For find a, the cost of avocados.

7g + 5a = 51..... Equation 3

g = $3

7(3) + 5a = 51

21 + 5a = 51

5a = 51 - 21

5a = 30

a = 30/5

a = $6

g =$ 3, s =$ 2.5 and a = $6.

Therefore:

The cost of grapefruits per box is $3.

The cost of strawberries per box is $2.5 and

The cost of avocados per box is $6

Answer: one solution I believe

Step-by-step explanation: I got 21 as my answer and that is one solution

Answer:

on the number its between 0 and 1

Step-by-step explanation:

if you jump from 0 to 6 you would have 6 jumps, so it would be 6.

0.6 equals 0.60 so it could ALSO be 60 jumps. (incase u needed that)

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
