What is the scale factor of the dilation?

Answer:

D

Step-by-step explanation:

Mathematically, the mid segment of a trapezoid is exactly the average of the 2 parallel bases

What this means is that to find the length of the trapezoid, we will need to find the average of the two parallel bases

Mathematically, this is same as adding the two bases and dividing the result by 2.

Hence we can say it is exactly one-half the length of the sum of the two parallel bases

Answer:

(10/3)π units

Step-by-step explanation:

120 degrees is equivalent to (2π)/3 radians.  Applying the arc length formula s = r Ф, we get:

s = arc length = (5 units)(2π)/3 = (10/3)π units

Answer:

4 monetary units

Step-by-step explanation:

In a Poisson distribution, the expected value of the distribution is the same as the mean:

[tex]E(X)=\mu=4\ claims[/tex]

The expected number of warranty claims is 4.

Since each claim results in a payment of 1, the expected value paid by the insurer is:

[tex]E(V)=E(X)*V(X)\\E(V)=4*1 = 4[/tex]

The expected total payment on warranty claims is 4 monetary units.

Answer:  3/5

Step-by-step explanation:

[tex]\dfrac{a}{a+2}+\dfrac{3}{20}=\dfrac{a+3}{(a+2)+3}\\\\\\\dfrac{a}{a+2}\bigg(\dfrac{20}{20}\bigg)+\dfrac{3}{20}\bigg(\dfrac{a+2}{a+2}\bigg)=\dfrac{a+3}{a+5}\\\\\\\dfrac{23a+6}{20(a+2)}=\dfrac{a+3}{a+5}\\\\\\(23a+6)(a+5)=20(a+2)(a+3)\\\\\\23a^2+121a+30=20a^2+100a+120\\\\\\3a^2+21a-90=0\\\\\\a^2+7a-30=0\\\\\\(a+10)(a-3)=0\\\\\\a=-10\quad a=3[/tex]

Since "a" is a positive integer, disregard a = -10

So the only valid answer is a=3   →  a+2=5

[tex]\dfrac{a}{a+2}=\large\boxed{\dfrac{3}{5}}[/tex]

Using the probability concept, it is found that there is a 0.375 = 37.5% probability that she will pick either a yellow or orange sweet.

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem:

The probability that she will pick either a yellow or orange sweet is:

[tex]p = \frac{D}{T} = \frac{9}{24} = 0.375[/tex]

0.375 = 37.5% probability that she will pick either a yellow or orange sweet.

Number of yellow sweet = 5

Number of red sweet = 4

Number of green sweet = 8

Number of orange sweet = 4

Number of white sweet = 3

Find:

Probability to pick yellow or orange sweet

Computation:

Total number of sweets = 24 sweets

Probability to pick yellow = 5 / 24

Probability to pick orange = 4 / 24

Probability to pick yellow or orange sweet = 5/24 + 4/24

Probability to pick yellow or orange sweet = 9 / 24

Answer:

x < -9 or  x ≥ 6

Step-by-step explanation:

6 – x > 15 or 2x – 9 ≥ 3

Solve each inequality

6-x > 15

Subtract 6 from each side

6-x-6 > 15-6

-x > 9

Multiply by -1 remembering to flip the inequality

x < -9

Then the other inequality

2x – 9 ≥ 3

Add 9 to each side

2x -9+9≥ 3 +9

2x≥ 12

Divide by 2

2x/2 ≥ 12/2

x ≥ 6

Put back together

x < -9 or  x ≥ 6

Answer:

y = kx  where k>0

Step-by-step explanation:

A direct variation is in the form

y = kx

where k is a numerical positive constant ( i.e. > 0 )

Answer:

0

Step-by-step explanation:

If she puts 0 in the box she would have a direct variation.

Step-by-step explanation:

 Given : She writes the equation y = 5x - __ with a missing value.

She puts a value in the box and says that the equation represents a direct variation.

We have to choose the correct option from the given options that explain that  the equation could represent a direct variation.

When two variables are such that one is a constant multiple of other, we said they are in Direct variation.

That is in form of y = ax , here y and x are in direct variation.

Consider the given equation y = 5x  - __

For the equation to be in direct variation the value of missing term has to be 0.

then equation becomes,

y = 5x

Thus, If she puts 0 in the box she would have a direct variation.

Answer:

A. y = x² - 9x + 18

Step-by-step explanation:

The key thing to look for in this graph is the y-intercept (where the graph will hit the y-axis).

We can't see exactly where y-intercept is, but we know it is a positive number.

In a standard form quadratic equation:

y = ax² + bx + c

'c' tells you what the y-intercept is.

The choices with positive y-intercept are A and B.

Again, we can't see exactly where y-intercept is, but we know it is not 1.

y = x² - 9x + 18

has a positive y-intercept that is not 1,

thus the answer is A.

Answer:

  117

Step-by-step explanation:

Let d represent the number of stamps Derek had at first. After he gave 1/9 of his stamps to Ahmad, Ahmad had (d -104) +(d/9). Derek had 4 times this number after giving away d/9 stamps:

  (d -d/9) = 4((d -104) +d/9)

  (8/9)d = 4d -416 +(4/9)d

  416 = (32/9)d . . . . add 416 -8/9d

  117 = d . . . . . . . . . . multiply by 9/32

Derek had 117 stamps at first.

_____

Check

1/9 of Derek's collection is 13 stamps. 104 less than Derek's collection is 13 stamps.

So, Ahmad started with 13 stamps and was given 13 stamps by Derek. Meanwhile, Derek started with 117 stamps and gave away 13, so ended with 104 stamps. That number (104) is 4 times Ahmad's new number (26), as it should be.

Answer:

2d^0.7

Step-by-step explanation:

Answer: C. 72

Step-by-step explanation:

The set is:

{R, E, L, O, A, D}

if we separate it into consonants and vowels, we have

consonants: {R, L, D}

vowels : {E, O, A}

Now, we want combinations of 3 consonants and one vowel.

we have 4-letters combinations, let's fixate the first letter as the vowel,

for this first letter, we have 3 options {E, O, A}

for the second letter, a consonant, we also have 3 options  {R, L, D}

for the third letter, we also need to choose a consonant, but now we have 2 options (because we already selected one)

for the fourth letter, we have only one option.

Now, the total number of combinations is equal to the product of the number of options in each selection:

C = 3*3*2*1 = 18

But remember that this is the case where the vowel is fixed for the first letter, we have 4 positions where the vowel can be (first, second, etc)

So the actual number of combinations is:

C*4 = 18*4 = 72

The correct option is C.
