Step-by-step explanation:

Perimeter : sum of the sides

Answer:

M = 2

Step-by-step explanation:

3M+4/3 = 28/3 -M

3M+M +4/3-28/3 = 0

4M -8 = 0

4M = 8 ( divide 4 in both sides)

M=8/4

M=2

The probability of getting three tails in three tosses When Mickey tosses a coin 50 times and records 27 heads is 12,167:125,000.

It is the ratio in an event of the number of favorable outcome to the total number of outcome of that event.

As the probability of an event can not be more than the number 1. Thus, he probability of failure of a event is equal to the difference of the 1 to the success of the event.

Mickey tosses a coin 50 times and records 27 heads. Thus, the probability of getting a head is,

[tex]P=\dfrac{27}{50}\\[/tex]

The probability of not getting a head or getting a tail is,

[tex]P^{-1}=1-\dfrac{27}{50}\\P^{-1}=\dfrac{50-27}{50}\\P^{-1}=\dfrac{23}{50}[/tex]

Now, Mickey tosses the same coin three more times. The probability of getting three tails in these tosses are,

[tex]P_{3t}=\dfrac{23}{50}\times\dfrac{23}{50}\times\dfrac{23}{50}\\P_{3t}=\dfrac{12167}{125000}[/tex]

Thus, the probability of getting three tails in three tosses When Mickey tosses a coin 50 times and records 27 heads is 12,167:125,000.

Answer:

C. 54 tens

Step-by-step explanation:

54×10=540

54tens=540

Answer:

54 tens

Step-by-step explanation:

This is like regular multiplication, sort of.

54 x 10= 540

540=54

Answer:

813.75

Step-by-step explanation:

area of a regular polygon = side length × # of sides × apothem × 1/2

here side length = 15 , # of sides = 7 ( a heptagon has 7 sides ) and apothem = 15.5

so area = 15 × 7 × 15.5 × 1/2

==> multiply 15 by 7 by 15.5

area = 1627.5 × 1/2

==> divide 1627.5 by 2

area = 813.75

Answer:

Step-by-step explanation:

32.8 = 164/5

= 32/4/5

as a fraction

To convert the decimal 32.8 to a fraction, just follow these steps:

Step 1: Write down the number as a fraction of one:

32.8 = 32.8/1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,

32.8

1

= (32.8 × 10)

(1 × 10)

= 328/10

.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(328,10) = 2. So,

(328÷2)

(10÷2)

= 164/5

when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 328/ 10

is also equal to 32/4 /5

when expressed as a mixed number.

The functions f(x) and h(x) have an axis of symmetry of x = 2 and a maximum

The functions are given as:

A quadratic function can be represented as:

y = ax² + bx + c

y = a(x - h)² + k

In both cases, when a < 0; the function has a maximum.

This means that all three functions have a maximum.

Next, we determine the axis of symmetry:

Using the above forms, we have:

f(x) = -x² + 4x + 2

Axis of symmetry, x = -4/(2 * -1)

x = 2

g(x) = -(x + 2)² - 5

Axis of symmetry, x = -2

h(x) = -2(x − 1)(x − 3)

Expand

h(x) = -2x² - 8x + 8

Axis of symmetry, x = -8/(2 * -2)

x = 2

This means that f(x) and h(x) have an axis of symmetry of x = 2

Hence, the functions f(x) and h(x) have an axis of symmetry of x = 2 and a maximum

solved it using a software. check attachment for all the steps

The integer representing the change in the number of DVDs sold is -10000.

Given, The number of DVDs shipped to an online retailer was 10,000 less than the previous year.  

We have to Use an integer to describe the change in the number of DVDs sold.

Now, let the number of DVDs shipped to an online retailer in the previous year be x.

Then, according to the given information, DVDs shipped to the online retailer this year will become x – 10000

So, now, the change in the number of DVDs sold = DVDs sold this year – DVDs sold last year

= x – 10000 – x

= 0 – 10000

= - 10000

Hence, the integer representing the change in the number of DVDs sold is -10000.

Answer:

4/10 or 40% chance he picks a spade and 3/10 or 30% he picks a club so in total he would have a 7/10 chance or 70% chance of getting spade or club

Step-by-step explanation:

The probability that Wes will pick a spade or a club from Alex's cards is 0.7 or 70%.

To find the probability that Wes will pick a spade or a club from Alex's cards, we need to determine the total number of spades and clubs in Alex's hand and divide it by the total number of cards.

Total number of spades = 3

Total number of clubs = 4

Total number of cards = 2 (diamonds) + 3 (spades) + 4 (clubs) + 1 (heart) = 10

Therefore, the probability that Wes will pick a spade or a club is:

(Picking spade or club) = (Total number of spades + Total number of clubs) / Total number of cards

= (3 + 4) / 10

= 7 / 10

= 0.7

So, the probability that Wes will pick a spade or a club from Alex's cards is 0.7 or 70%.

Step-by-step explanation:

Step-by-step explanation:

scientific notation is

a.b × 10^c

with a being <> 0.

0.0002 cm = 2.0×10^-4 cm (the "2" moves 4 positions to the right for the actual number).

so, this is between 1.0×10^-4 cm and 1.0×10^-3 cm.

0.02 cm = 2.0×10^-2 cm (the "2" only need to move 2 positions to the right for the actual number).

so, this is between 1.0×10-2 cm and 1.0×10^-1 cm.

200 cm = 2.0×10² cm (now the "2" needs to move 2 positions to the left for the actual number).

so, this is between 1.0×10² cm and 1.0×10³ cm.

20,000 cm = 2.0×10⁴ cm (the "2" has to move 4 positions to the left for the actual number).

so, this is between 1.0×10⁴ cm and 1.0×10⁵ cm.

1 is d

the square root of 36 = 6 which is the only equation with 36

2 is d

Answer:

-1/2 = x
OR
-0.5 = x

Step-by-step explanation:

1) Isolate x from the equation by making it equal to zero
(Reminder that everything crossing over to the other side of the equation changes it's symbols from positive to negative, and vice-versa is the original symbol was negative)

-7 + 13 + 8x - 2 = 0
-7 + 13 - 2 = -8x

2) Add up common terms on the left side

-9 + 13 = -8x
4 = -8x

3) Divide the entire equation by the number that would leave "x" by itself the factor or number that leaves the number by itself is negative eight since its the number with the equation (-8)

4/-8 = -8x/-8
-1/2 = x
OR
-0.5 = x

For parent function f(x) with vertex at (0, 0), translating it horizontally by "h" and vertically by "k" makes it look like

  f(x -h) +k

and the vertex moves to (h, k).

Here, the parent function |x| has its vertex at (0, 0). Writing it as ...

  -3|x -5| +2

moves its vertex to (h, k) = (5, 2).

The factor -3 serves to reflect the graph over the x-axis and expand it vertically by a factor of 3. It has no effect on the translation of the vertex.
