Pls explain how to do this

Answer:

1 / 30

Step-by-step explanation:

For a six - sided die :

Sample space = (1, 2, 3, 4, 5, 6)

P(rolling a 1) = required outcome / sample space = 1/6

Sample space for spinner = (A, B, C, D, E)

P(spinning A ) = required outcome / sample space = 1/5

P(spinning A) = 1 / 5

P(rolling a 1 and spinning A) = P(rolling a 1) * P(spinning A) = 1/6 * 1/5 = 1 / 30

Answer:

Step-by-step explanation:

Assume that  and multiply the equation  by 4p. Then you obtain the equation (x-h)^2+4pk=0.

1) If k>0, then 4pk>0 and the equation does not have real solutions and there is no zero.

2) If k=0, then 4pk=0 and . There is one solution x=h and there is one zero.

2) If k<0, then 4pk<0 and the equation  has two different solutions and there are two zeros.

Answer:

Given equation:

Multiply this by 4p to get:

Rewrite this as:

1) If p > 0 and k < 0

2) If p > 0 and k = 0

3) If p > 0 and k > 0

Answer:

248 cm^2

Step-by-step explanation:

in order to get the figures surface area you only need to find the area of all 6 sides

in this case the two ends are 4 by 6

the front and back are 10 by 6

and the top and bottom are 10 by 4

this would mean that we need to multiply

(4*6)*2

(10*6)*2

(10*4)*2

which would look like

(4*6)*2= (24)*2= 48

(10*6)*2= (60)*2=120

(10*4)*2= (40)*2=80

and finally the sum of the equations is the surface area of the figure

48+120+80=248

Answer:

10 combinations

Step-by-step explanation:

We can solve the above question using the Fundamental Counting Principle.

This states that:

If an event has x possible outcomes and a other event has y possible outcomes, then there are x and y total possible outcomes for the two events together.

We are told in the above question that:

Styles of jeans = 2

Number of colors = 5

Hence,the number of combinations of a style and a colour that are possible is calculated as:

5 × 2 = 10 combinations

Answer:

The possible length of the triangle =

1) (1inches, 196inches)

2) (2incheq, 98inches)

3) (4inches , 49 inches)

4) (7 inches , 28 inches)

Step-by-step explanation:

We are told the above Triangle is not an Isosceles Triangle

Hence, we assume it is a right angle triangle

The area of a triangle is = 1/2 × Base × Height

= let us represent Base and Height = x

Hence:

1/2 × x × x = 98

x² /2 = 98

Cross Multiply

x² = 98 × 2

x² = 196

Step 2

We find the factors of 196

1× 196 = 196 (1, 196)

2 × 98 = 196 (2, 98)

4 ×49 = 196 (4, 49)

7 × 28 = 196 (7, 28)

Therefore, all the possible length of the triangle =

1) (1inches, 196inches)

2) (2incheq, 98inches)

3) (4inches , 49 inches)

4) (7 inches , 28 inches)

Answer:

Approximately = 131 employees in total

Step-by-step explanation:

if the 55 employees who work overtime make up approximately 42% of all employees at the company, how many employees are there in total?

Let us represent total number of employees = x

Hence,

42% of x = 55 employees

42/100 × x = 55

42x/100 = 55

Cross Multiply

42x = 100 × 54

x = 100 × 55/42

x = 130.95238095 employees

Therefore, there is approximately a total 131 employees

Answer:

∠1 = 51°   ∠2 = 39°

Step-by-step explanation:

ok since the picture is a right angle put it equal to 90

like this:

3x + x + 22 =90

4x + 22 = 90

4x = 68

x = 17

now we plug it in:

3(17)= 51°

(17) + 22 = 39°

*a straight line is equal to 180, a right angle is 90

does that make sense?

Answer:

D.) the amount in the account increase by 4% each year

Step-by-step explanation:

Compound interest formula: P*(1+r/n)^(nt)

P=initial principal balance

r=interest rate

n=times applied per [time (eg year)]

t=number of time periods gone by

The expression: 2500(1.04)^x

The expression: 2500(1+1/25)^(nt)

1.04=1+1/25=increases by 4% each year

Question is incomplete as number of trials isn't given. We'll use an hypothetical value to make x plain the situation

Answer:

Kindly check explanation

Step-by-step explanation:

Given that the number of trials = x

If the number of tines the ball was hit out if 'x' trials = 3

The ratio of the number of hits to the number of trials is written as :

Number of hits : Number of trials

3 : x

Just put the exact value of x in the equation above and if possible, reduce to simplest form.

Answer:

t = 68000 s

Step-by-step explanation:

Given that,

The average time Sally spent for training for her weight lifting competition in the month of May is [tex]6.8\times 10^4\ s[/tex].

We need to write this time in standard notation.

The power of 10 is 4. 10⁴ can be written as 10000.

[tex]6.8\times 10^4=\dfrac{68}{10}\times 10000\\\\=68000[/tex]

So, the standard time is equal to 68000 s.

Answer:

Median= 9

Range= 2

Mean= 9.2

Mean after zero= 8.3

Step-by-step explanation:

8, 8, 9, 9, 9, 10, 10, 10, 10

Median= order from least to greatest then eliminate from left to right until you get to the middle

Range= Subtract biggest # minus smallest #

Mean= add up all the numbers then divide by 9

Mean after zero= add 0 with other numbers then divide by 10

Answer:

The answer to each question is:

Step-by-step explanation:

A.) To obtain the area of the dodecagon, you can use the next formula:

In the exercise, we have the edge (6 cm), but, to find the apothem of a dodecagon, that is the distance between the center of the polygon, and the middle point of each side, you can use the next formula:

If we replace the value of the edge, we obtain:

With this data, we can find the area:

Then, the area of the dodecagon is 403.2 [tex]cm^{2}[/tex] approximately.

B.) As the area obtained is for 12 pieces, when the parents ate 9 pieces, just left 3 pieces, with these values you can make a rule of three.

If:

Then:

In this form, when the cookie has 3 pieces, its area is 100. 8 [tex]cm^{2}[/tex] approximately.

Answer:

x = 4  ± √11

Step-by-step explanation:

hello :

x²-8x+5=  x² -2(4 )(x)+5

 x²-8x+5=  x² -2(4 )(x)+5 =  ( x² -2(4 )(x) +4²) -4²+5

                                      = (x-4)²-11 .....(   completing the square )

    x²-8x+5= 0   means :      (x-4)²-11 = 0

      (x-4)²=11      but : 11 =   (√11)²  =  ( - √11)²

x-4 =√11   or    x-4 =  -√11

x = 4  ± √11                                                  

Answer:

x = 4 ± [tex]\sqrt{11}[/tex]

Step-by-step explanation:

To solve the equation let y = 0 , that is

x² - 8x + 5 = 0 ( subtract 5 from both sides )

x² - 8x = - 5

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 4)x + 16 = - 5 + 16

(x - 4)² = 11 ( take the square root of both sides )

x - 4 = ± [tex]\sqrt{11}[/tex] ( add 4 to both sides )

x = 4 ± [tex]\sqrt{11}[/tex]

Answer:

6 and 12

Explanation:

(b.) is under set A but not set B, meaning that all the elements there are multiples of 3 that are not odd numbers.

all the multiples of 3 that are less than 16: 3 6 9 12 15

all the multiples of 3 that are even numbers: 6 12

thus, the elements that go in (b.) are 6 and 12.
