IF YOU DONT ANSWER THIS AND GET IT RIGHT YOUR MOM IS PREGO WITH YOUR KID a store sells pencils pens and markers that sells two times as many markers as pencils and three times as many pens as pencils is the store sells a total of 1950 pencils and pens and markers in a week how many of each were sold​

Answers

Answer 1

Answer:

Pencils = 325 ; Pens = 975 ; Markers = 650

Step-by-step explanation:

Let :

Number of Pencils = x

Number of pens = y

Number of markers = z

2 times as many markers as pencils

z = 2x

3 times as many pens as pencils

y = 3x

x + y + z = 1950

Write z and y in terms of x in the equation :

x + 3x + 2x = 1950

6x = 1950

Divide both sides by 6

6x / 6 = 1950 / 6

x = 325

Number of pencils = 325

Pens = 3 * 325 = 975

Markers = 2 * 325 = 650

Pencils = 325 ; Pens = 975 ; Markers = 650

Answer:

  (-3, 3)

Step-by-step explanation:

The blanks are trying to lead you through the process of finding the point of interest.

__

The horizontal distance from T to S is 9 . (or -9, if you prefer)

The ratio you're trying to divide the line into is the ratio that goes in this blank:

Multiply the horizontal distance by 2/3 . (9×2/3 = 6)

Move 6 units left from point T.

The vertical distance from T to S is 6 .

Multiply the vertical distance by 2/3 . (6×2/3 = 4)

Move 4 units up from point T.

__

Point T is (3, -1) so 6 left and 4 up is (3, -1) +(-6, 4) = (3-6, -1+4) = (-3, 3). The point that is 2/3 of the way from T to S is (-3, 3).

Answer:

[tex]f(-1)=7[/tex]

Step-by-step explanation:

I am going to assume your question meant the equation

[tex]f(x)=2x^{2} -4x+1[/tex]

So [tex]f(-1)[/tex] can be found by substituting all the x terms in the equation with -1

[tex]f(-1)=2(-1)^{2} -4(-1)+1[/tex]

And simplifying for our answer

[tex]f(-1)=2(1)+4+1[/tex]

F and H are connected by a segment, and F prime and H prime are also connected by a segment. Quadrilateral EFGH was dilated by a scale factor of 2 from the center (1, 0) to create E'F'G'H'. Which characteristic of dilations compares segment F'H' to segment FH

Answers

Answer:

[tex]|F'H'| = 2 * |FH|[/tex]

Step-by-step explanation:

Given

[tex]E = (0,1)[/tex]             [tex]E' = (-1,2)[/tex]

[tex]F = (1,1)[/tex]             [tex]F' = (1,2)[/tex]

[tex]G = (2,0)[/tex]             [tex]G' =(3,0)[/tex]

[tex]H = (0,0)[/tex]            [tex]H' = (-1,0)[/tex]

[tex](x,y) = (1,0)[/tex] -- center

[tex]k = 2[/tex] --- scale factor

See comment for proper format of question

Required

Compare FH to F'H'

From the question, we understand that the scale of dilation from EFGH to E'F'G'H is 2;

Irrespective of the center of dilation, the distance between corresponding segment will maintain the scale of dilation.

i.e.

[tex]|F'H'| = k * |FH|[/tex]

[tex]|F'H'| = 2 * |FH|[/tex]

To prove this;

Calculate distance of segments FH and F'H' using:

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

Given that:

[tex]F = (1,1)[/tex]             [tex]F' = (1,2)[/tex]

[tex]H = (0,0)[/tex]            [tex]H' = (-1,0)[/tex]

We have:

[tex]FH = \sqrt{(1- 0)^2 + (1- 0)^2}[/tex]

[tex]FH = \sqrt{(1)^2 + (1)^2}[/tex]

[tex]FH = \sqrt{1 + 1}[/tex]

[tex]FH = \sqrt{2}[/tex]

Similarly;

[tex]F'H' = \sqrt{(1 --1)^2 + (2 -0)^2}[/tex]

[tex]F'H' = \sqrt{(2)^2 + (2)^2}[/tex]

Distribute

[tex]F'H' = \sqrt{(2)^2(1 +1)}[/tex]

[tex]F'H' = \sqrt{(2)^2*2}[/tex]

Split

[tex]F'H' = \sqrt{(2)^2} *\sqrt{2}[/tex]

[tex]F'H' = 2 *\sqrt{2}[/tex]

[tex]F'H' = 2\sqrt{2}[/tex]

Recall that:

[tex]|F'H'| = 2 * |FH|[/tex]

So, we have:

[tex]2\sqrt 2 = 2 * \sqrt 2[/tex]

[tex]2\sqrt 2 = 2\sqrt 2[/tex] --- true

Hence, the dilation relationship between FH and F'H' is::

[tex]|F'H'| = 2 * |FH|[/tex]

Find the probability of 3 success for the binomial experiment with 7 trial and the success probability of 0.3. Then find the mean and standard deviation. Write the formula substitute
the values.

Answers

Answer:

[tex]P(x=3)=0.2269[/tex]

Mean=2.1

Standard deviation=1.21

Step-by-step explanation:

We are given that

n=7

Probability of success, p=0.3

q=1-p=1-0.3=0.7

We have to find the probability of 3 success for the binomial experiment  and find the mean and standard deviation.

Binomial distribution formula

[tex]P(X=x)=nC_xp^{x}q^{n-x}[/tex]

Using the formula

[tex]P(x=3)=7C_3(0.3)^3(0.7)^{7-3}[/tex]

[tex]P(x=3)=7C_3(0.3)^3(0.7)^{4}[/tex]

[tex]P(x=3)=\frac{7!}{3!4!}(0.3)^3(0.7)^{4}[/tex]

[tex]P(x=3)=\frac{7\times 6\times 5\times 4!}{3\times 2\times 1\times 4!}(0.3)^{3}(0.7)^{4}[/tex]

Using the formula

[tex]nC_r=\frac{n!}{r!(n-r)!}[/tex]

[tex]P(x=3)=0.2269[/tex]

Now,

Mean, [tex]\mu=np=7\times 0.3=2.1[/tex]

Standard deviation, [tex]\sigma=\sqrt{np(1-p)}[/tex]

Standard deviation, [tex]\sigma=\sqrt{7\times 0.3\times 0.7}[/tex]

Standard deviation, [tex]\sigma=1.21[/tex]

lisa used 880g of a container of sugar to bake a cake and 1/10 of the creaming sugar to make cookies. She then had 3/7 of the container of sugar left. How much sugar was in the container at first

Answers

Answer:

At the beginning, there were 2,678.26 grams of sugar in the container.

Step-by-step explanation:

Since Lisa used 880g of a container of sugar to bake a cake and 1/10 of the creaming sugar to make cookies, and she then had 3/7 of the container of sugar left, to determine how much sugar was in the container at first, the following calculation must be performed:

880 + 1 / 10X = 3 / 7X

880 + 0.1X = 0.4285X

880 = 0.4285X - 0.1X

880 = 0.3285X

880 / 0.3285 = X

2,678.26 = X

Therefore, at the beginning there were 2,678.26 grams of sugar in the container.

Which of the following is the absolute value of 6 − 3i?

A) 3i√3

B) 3√5

C) 3√5i

D) 3√3

Answers

Answer:

B

Step-by-step explanation:

We want to find the value of:

[tex]\displaystyle |6-3i|[/tex]

Recall that given a complex number z in the form:

[tex]z=a+bi[/tex]

The absolute value of z will be given by:

[tex]\displaystyle |z| = \sqrt{a^2+b^2}[/tex]

We have the complex number:

[tex]6-3i[/tex]

Thus, a = 6 and b = -3.

Then its absolute value will be:

[tex]|6-3i|=\sqrt{(6)^2+(-3)^2}[/tex]

Evaluate:

[tex]\displaystyle |6-3i|= \sqrt{36+9}=\sqrt{45}=3\sqrt{5}[/tex]

And also that Martha's probability if winning is lower Than that of Elena ; Hence, Martha's outcome should be outcjnes whose probability is less than 1/6 (Elena's probability of winning)

Using a sample space that gives the sum of 2 dices.

Total possible outcomes for a two dice throw = 6² = 36

Using the sample space attached, we can count the sums from the sample space :

To obtain a sum of 7 :

P(sum 7) = 6 /36 = 1/6

To obtain a sum of 6 :

B. f(x)=$+4 and g(x) = 3x-4
C. f(x)=5+*fx and g(x) = 5 - 43
O D. f(x) = 3-6 and g(x) = x26

Answers

Answer:

I  think its B

Step-by-step explanation:

The pairs of functions which are inverses of each other is A. f(x) = 2x - 9 and g(x) = (x + 9)/2.

What is Inverse Function?

Inverse functions are functions which can be reversed in to another function.

Then the function is said to be the inverse of the second function.

If two functions f(x) and g(x) are inverses of each other, then f(g(x) = x and g(f(x)) = x.

A. f(x) = 2x - 9 and g(x) = (x + 9)/2

f(g(x)) = f((x + 9)/2) = 2 [(x + 9)/2] - 9 = x + 9 - 9 = x

g(f(x)) = g(2x - 9) = (2x - 9 + 9) / 2 = 2x / 2 = x

So, the functions are inverses of each other.

B. f(x) = (x/3) + 4 and g(x) = 3x - 4

f(g(x)) = f(3x - 4) = [(3x - 4)/3] + 4 ≠ x

So not inverses of each other.

C. f(x) = 5 + ∛x and g(x) = 5 - x³

f(g(x)) = f(5 - x³) = 5 + ∛(5 - x³) ≠ x

So not inverses of each other.

D. f(x) = (2/x) - 6 and g(x) = (x + 6)/2

f(g(x)) = f((x + 6)/2) = [2 / ((x + 6)/2)] - 6 ≠ x

So not inverses of each other.

Hence the correct option is A.

Heron was large and slow, with a long, gangly neck and big, floppy wings. Hummingbird was tiny and swift, with wings that moved so quickly that they buzzed and a slender beak as sleek as a needle.Heron and Hummingbird both loved to eat fish from the river. Every morning, Heron would fish to her heart's content, eating until her stomach was so round and heavy that she had to waddle back to shore. Every afternoon, Hummingbird would fish and feast until he was so heavy that his tiny, buzzing wings could no longer keep him in the air. Heron and Hummingbird thought they were the luckiest birds in the world.One afternoon, Hummingbird did not catch as many fish as usual. He fished and he fished, but his line came up empty more times than it ever had before. He flew to Heron's house."Heron! Heron!" he called. "Why have you eaten all the fish?"Heron bustled to her door, angry and surprised at her friend's accusation."Me? Eat all the fish?" she squawked. "I barely caught anything this morning! My poor stomach has been growling all day."How does the narrator's point of view influence the description of events?The narrator's point of view allows the reader to know exactly what Heron is thinking when he doesn't catch any fish.
