Convert the following into scientific notation:
70.2 = _____ x 10 ____

Answer:

Well, lets break this down.

If you try to add 26 + 26 it would be 52, which is above 48.

So, we have to find how many books he can read in one month.

All we have to do, is divide!

14 = dividend

26 = divisor

Step 1:

Start by setting it up with the divisor 26 on the left side and the dividend 14 on the right side like this:

26⟌14 Then do the rest, ill wait.

once you have a answer, that is how much he reads a month.

now multiply by 48.

Step-by-step explanation:

Hey there!

Given; 3y - 5(y+2).

Multiply 5 and (y+2)

3y - 5y - 10

Simplify to get answer.

-2y -10

Take 2 and (-) common.

-2(y+5)

Therefore, the simplified form is -2(y+5).

Hope it helps...

Probability of being left handed = 0.13

Probability of being not left handed = 1-0.13 =0.87

They select a sample of five customers at random in their stores

a. The first lefty is the fifth person chosen

Probability that first lefty is the fifth person chosen =[tex]0.87 \times 0.87 \times 0.87 \times 0.87 \times 0.13=0.074[/tex]

b)There are some lefties among the 5 people=[tex]1-P(x=0)=1-0.87^5=0.502[/tex]

c)The first lefty is the second or third person=[tex]0.87 \times 0.13 + 0.87 \times 0.87 \times 0.13 =0.2114[/tex]

d)

[tex]P(x=3)=^5C_3 (0.13)^3 (0.87)^2=\frac{5!}{3!2!}(0.13)^3 (0.87)^2=0.0166[/tex]

e)

[tex]P(x\geq 3)=P(x=3)+P(x=4)+P(x=5)\\P(x\geq 3)=\frac{5!}{3!2!}(0.13)^3 (0.87)^2+\frac{5!}{4!1!}(0.13)^4(0.87)^1+\frac{5!}{5!0!}(0.13)^5 (0.87)^0=0.01790[/tex]

f)

[tex]P(x\leq 3)=P(x=0)+P(x=1)+P(x=2)+P(x=3)[/tex]

[tex]P(x\leq 3)=\frac{5!}{0!5!}(0.13)^0 (0.87)^5+\frac{5!}{4!1!}(0.13)^1(0.87)^4+\frac{5!}{2!3!}(0.13)^2 (0.87)^3+\frac{5!}{2!3!}(0.13)^3 (0.87)^2=0.9987[/tex]

The probability is  [tex]P(X = 2)= 0.0729[/tex]

Step-by-step explanation:

From the question we are told that

   The percentage that the donor is compactible is  p = 0.10

   The sample size is  n  =  5

   Generally the probability that the donor is not compactible is  

      [tex]q =  1- p[/tex]

=>    [tex]q =  1- 0.10 [/tex]

=>    [tex]q = 0.90 [/tex]

Generally the probability that the  exactly 2 of the selected donors is compatible mathematically represented as

    [tex]P(X = 2)= \  ^{5}C_2 *  p^2 *  q^{5-2}[/tex]

Here C standards for  combination

=>   [tex]P(X = 2)= \  10 *  0.10^2 *  0.90 ^{5-2}[/tex]

=>   [tex]P(X = 2)= 0.0729[/tex]

The slope should be 2 from the parallel line

Step-by-step explanation:

Hope this helps!

Hello! (:

Since parallel lines have the same slope, then the line has a slope of 2.

So, if the given line has a slope of 2, then the line parallel to it has a slope of 2 as well.

Hope it helps!

Answer:

There were 14 red-haired people accumulated in Beaumont, for this year.

Step-by-step explanation:

        Number of dark haired people = 180

        Number of red haired people = 260

        Number of blonde haired people = 360

        Number of dark haired people = 470

        Number of red haired people = 270

        Number of blonde haired people = 330

        Number of dark haired = 47

        Number of red haired = 90

        Number of blonde haired = 86

        Number of dark haired people = 31

        Number of red haired people = 66

        Number of blonde haired people = 71

Compute the accumulation of red-haired people in Beaumont, for this year as follows:

Red hair = #Moved in - #Moved out + #Newborn - #Deaths

              = 260 - 270 + 90 - 66

              = 14

Thus, there were 14 red-haired people accumulated in Beaumont, for this year.

Step-by-step explanation:

The amplitude of the function is 48 units.

The period of the function is 28 units.

The graph has a vertical shift of 48 unit.

To determine the amplitude and period of the cosine function that describes the relationship between the day (d) and the illuminated percentage of the moon (%), we can analyze the given data:

d     %

0   48

14   96

21  48

28   0

Amplitude:

The amplitude of a cosine function represents half the difference between the maximum and minimum values of the function.

So, (96 - 0) / 2

= 48 units.

Period:

The period of a cosine function is the length of one complete cycle.

Therefore, the period of the function is 28 units.

Vertical shift:

The vertical shift represents the displacement of the graph vertically.

The graph has a vertical shift of 48 unit.

Answer:

4.10

0.17

Step-by-step explanation:

From the question, we know that

A recent sociological report stated that university students drink 4.10 alcoholic drinks per week on average, with a standard deviation of 1.9101.

Also, we're tasked with finding the mean and standard deviation of the sampling distribution of the sample mean alcohol consumption.

To find the mean of the sampling distribution, we take the sample mean of the same of that university students as a direct substitute. This then means that the mean of the sampling distribution of the sample mean alcohol consumption is 4.10 alcoholic drinks per week on average.

On the other hand, the standard deviation of the sampling distribution of the sample mean alcohol consumption is taken to be the division of the standard deviation of the sample mean. Mathematically, we have

Standard Deviation, S = 1.9101 / √125

Standard Deviation, S = 1.9101 / 11.18

Standard Deviation, S = 0.17

Therefore, the Standard Deviation is 0.17

Answer:

The values are

      [tex]\mu_{\= x } = \mu = 4.10[/tex]

And

      [tex]\sigma _{\= x} = 0.38202[/tex]

Step-by-step explanation:

The  population mean is  [tex]\mu = 4.10[/tex]

 The  standard deviation is  [tex]\sigma = 1.9101[/tex]

  The sample size is  n  =  125 students

Generally the mean of the sampling distribution of the sample mean is equivalent to the population mean

  i.e  [tex]\mu_{\= x } = \mu = 4.10[/tex]

Generally the standard deviation of the sampling distribution of the sample mean alcohol consumption is mathematically represented as

      [tex]\sigma _{\= x} = \frac{\sigma }{\sqrt{n} }[/tex]

=>    [tex]\sigma _{\= x} = \frac{1.9101 }{\sqrt{125} }[/tex]

=>    [tex]\sigma _{\= x} = 0.38202[/tex]

Answer:

x > 7

Step-by-step explanation:

First, you start off with :

-8x + 40 > -16

Then you subtract 40 on both sides.

You get -8x > -56.

Next, you divide -8 on both sides. Cancel out the -8/-8.

After dividing,  you have x > 7

Therefore the answer is x > 7!

Answer:

C

Step-by-step explanation:

find the distance between the two points and divide that by 3 first,

then you estimate the point that is from point A with that 1/3 distance

The coordinate of point C such that point C on AB that is 1/3 the distance from point A to point B is (-3,-2) so option (C) will be correct.

A pair of numbers is used to express a point's position on a coordinate plane using the horizontal and vertical distinctions from the two reference axes. usually represented by pairs of x-values and y-values (x,y).

Coordinate a point with intercept m: n and bounded by coordinate (x₁, y₁) and (x₂, y₂) is given by

x = [m(x₂) + n(x₁)]/(m + n)

y = [m(y₂) + n(y₁)]/(m + n)

Here m = 1/3 and n = (1-1/3) = 2/3

And coordinates A(–7, –6) and B(5, 6).

So,

x = [ 1/3(5) + 2/3(-7) ]/ 1

x = -3

And,

y =  [ 1/3(6) + 2/3(-6) ]/ 1

y = -2

So (-3,-2) will be the coordinate of point C.

Hence "The coordinate of point C is (-3,-2).
