Andera worked 11 hour and 25 minutes last week at her job after school. How many minutes did she work?

Answer:

Step-by-step explanation:

n-(7+n) which is a strange problem to give you as that is equal to

n-7-n which always equals -7

And that means n can be any real number and the expression still equals -7

The algebraic expression will be -7. x is the assumed algebraic expression. The equation is solved by subtraction.

An algebraic expression is a phrase that has been combined using operations like addition.

Let n is the number and x be the solution for the given condition;

If the number is decreased by 7 then the equitation will be (n-7).

From the given condition;

[tex]\rm x=\rm n-(n-7) \\\\ x=n-n-7 \\\\ x=-7[/tex]

Hence the algebraic expression will be -7.

Answer:

P' = 1/3 P

reflection in the y-axis just changes the sign of all the x-values.

Since P" ≅ P', and P' is smaller than P, P" cannot be ≅ to P

It is, however, similar to P.

Answer: (x-4) is not a factor of the given polynomial.

===================================================

Explanation:

Rule: If (x-k) is a factor of p(x), then p(k) = 0. This is a special case of the remainder theorem. We can take this in reverse to say that if p(k) = 0, then (x-k) must be a factor of p(x).

In this case, we have k = 4 and we can find that:

p(x) = 2x^4-9x^3-20x^2+147x-180

p(4) = 2(4)^4-9(4)^3-20(4)^2+147(4)-180

p(4) = 24

The result we get is not zero, so that means (x-4) is not a factor of p(x).

Answer:

The population mean

Normally distributed

Please give me brainliest, I really need it.

a)As the number of surveys increases, the mean of the sample means will approach the population mean.

b)Means will be normally distributed.

A normal distribution is a probability distribution that is symmetric about the mean, and data near the mean are more frequent than data far from the mean.

As the number of surveys increases, we will have more data.

So, the mean of the sample means will approach the population mean.

Means will be normally distributed because each survey has the same number of respondents.

Thus, a)as the number of surveys increases, the mean of the sample means will approach the population mean.

b)Means will be normally distributed.

Answer:

126 passengers from Trinidad.

Step-by-step explanation:

Given that,

On a BWIA flight, 2/3 of the  passengers are from Trinidad.

Total passengers = 189

We need to find how many were from Trinidad. It can be calculated by finding 2/3 of 189 such that,

[tex]P=\dfrac{2}{3}\times 189\\\\=126[/tex]

Hence, there were 126 passengers from Trinidad.

Answer:

The length of AB is 18

Step-by-step explanation:

Do the pygotham theorem

24^2 + 7^2 = 625

Square root the answer

[tex]\sqrt{625}[/tex] = 25

Line BO equals 7 because CO is 7 and they are both radiuses

Subtract the answer to the length BO

25 - 7 = 18

18 is the length of AB bro

Answer:

[tex]Ratio =16 : 31[/tex]

Step-by-step explanation:

Let

x = Freddie's age and y = His mother's age

Given

2001:=  [tex]x : y = 1 : 11[/tex]

2018:= [tex]x +17: y + 17= 2 : 5[/tex]

Required

The ratio of their age in 2030

[tex]x : y = 1 : 11[/tex]

[tex]x +17: y + 17= 2 : 5[/tex]

Express as fractions

[tex]\frac{x}{y} = \frac{1}{11}[/tex] --- (1)

[tex]\frac{x+17}{y+17} = \frac{2}{5}[/tex] -- (2)

In (1), make y the subject

[tex]\frac{x}{y} = \frac{1}{11}[/tex]

[tex]y = 11x[/tex]

Substitute [tex]y = 11x[/tex] in (2)

[tex]\frac{x+17}{y+17} = \frac{2}{5}[/tex]

[tex]\frac{x+17}{11x+17} = \frac{2}{5}[/tex]

Cross Multiply

[tex]5(x +17) = 2(11x + 17)[/tex]

[tex]5x +85 = 22x + 34[/tex]

Collect like terms

[tex]22x - 5x = 85 - 34[/tex]

[tex]17x = 51[/tex]

[tex]x =3[/tex]

[tex]y = 11x[/tex]

[tex]y = 11*3[/tex]

[tex]y = 33[/tex]

This means that: In 2001, Freddie was 3 and his mother was 33

In 2030 (29 years after);

Freddie will be: 3 + 29 = 32

His mother will be: 33 + 29 = 62

So, the ratio is:

[tex]Ratio =32 : 62[/tex]

Divide by 2

[tex]Ratio =16 : 31[/tex]
