Answer:

13 of August,

Step-by-step explanation:

All of them worked together at day number zero (August 1).

We know that Elvis works every 3rd day

So he will work at:

day 3, day 6, day 9, etc.

We know that Izzy works every 4th day, then she will work at:

day 4, day 8, day 12, etc.

We know that Janaisa works every 6th day, so she will work at:

day 6, day 12, etc.

We just need to find a day where the 3 of them work, this is equivalent to finding a common multiple of the numbers: 3, 4 and 6.

To do it, we can just write the multiples of each one of these numbers and see which one is the first common multiple:

3)

3*1 = 3

3*2 = 6

3*3 = 9

3*4 = 12

3*5 = 15

...

4)

4*1 = 4

4*2 = 8

4*3 = 12

4*4 = 16

...

6)

6*1 = 6

6*2 = 12

So we can see that 12 is a common multiple of the 3 numbers.

Then they will work together 12 days after August 1th.

That would be the 13 of August,

Step-by-step explanation:

The probability that you win first prize and your friend wins second prize is given as follows:

B. 9/990.

A probability is calculated as the division of the desired number of outcomes by the total number of outcomes in the context of a problem/experiment.

The total number of outcomes is given as follows:

990.

The number of desired outcomes is of 9, as:

Hence:

1 x 1 x 9 = 9.

Meaning that the probability is of:

p = 9/990.

Answer:

0.1248 = 12.48% probability of getting 3 blues.

Step-by-step explanation:

The M&Ms are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x successes is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this question:

7 + 4 + 4 + 2 + 3 + 3 = 23 total M&Ms, which means that [tex]N = 23[/tex]

Sample of 5 means that [tex]n = 5[/tex]

7 blue means that [tex]k = 7[/tex]

What is the probability of getting 3 blues?

This is P(X = 3).

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 3) = h(3,23,5,7) = \frac{C_{7,3}*C_{16,2}}{C_{23,5}} = 0.1248[/tex]

0.1248 = 12.48% probability of getting 3 blues.

Answer:

B. y = 5x²

Step-by-step explanation:

As you can see, g(x) is a proper parabola, so it must be some variation of y = x².

Because the vertex of the parabola remains at (0, 0), know that there is no translation, so all we need to account for is the scale.

In the graph we can see that where x is equal to 1, y is equal to 5.  On a normal parabola that would instead be (1, 1), so we know that the y axis is scaled by a factor of five.  With that we can say that y = 5x².

Answer:

4x + 10

Step-by-step explanation:

Given

Let

[tex]t = time[/tex]

[tex]s = speed[/tex]

So:

[tex]t = 2; s = (2x +5)[/tex] --- first 2 hours

[tex]t = 3; s = (3x -5)[/tex] --- last 3 hours

Required

Distance covered in the first 2 hours

Distance (d) is calculated as:

[tex]Distance = speed * time[/tex]

i.e.

[tex]d = s * t[/tex]

For the first 2 hours, we have:

[tex]t = 2; s = (2x +5)[/tex]

So:

[tex]d = (2x + 5) * 2[/tex]

Open bracket

[tex]d =2x * 2 + 5 * 2[/tex]

[tex]d =4x + 10[/tex]

Hence, the distance covered in 4x + 10

Answer:

The answer is "-9".

Step-by-step explanation:

[tex]\mu = 11.4\\\\\sigma = 0.2\\\\ x = 10.9\\\\[/tex]

[tex]P(X <= 10.9)=?[/tex]

The z-value is determined using the central boundary theorem

[tex]z = \frac{(x - \mu)}{\sigma}[/tex]

  [tex]= \frac{(10.9 - 11.4)}{0.2}\\\\ = -2.5[/tex]

Calculating the value for Aaron

[tex]\mu = 11.5\\\\ \sigma = 0.1\\\\ x = 10.6\\\\ P(X <= 10.6)=?[/tex]

When the z-value is calculated using Central Limit Theorem

[tex]z = \frac{(x - \mu)}{\sigma}[/tex]

  [tex]= \frac{(10.6 - 11.5)}{0.1}\\\\ = -9[/tex]

Answer:

i need points rq thanks so much

Step-by-step explanation:

imma go waste these points now

She'll have $246 more purchasing power.

Current salary per year = $41000

Next year salary = $41000 × (2.5% × $41000)

= $41000 + (0.025 × $41000)

= $41000 + $1025

= $42025

Effect of Inflation will be:

= $41000 + (1.9% × $41000)

= $41000 + (0.019 × $41000)

= $41000 + $779

= $41779

Therefore, the difference will be:

= $42025 - $41779

= $246

Answer:

  7)  42 yd²

  8)  32 in²

Step-by-step explanation:

Put the given numbers in the appropriate area formula and do the arithmetic.

__

7) The area of a triangle is given by the formula ...

  A = 1/2bh . . . . . where b is the base length and h is the height

  A = 1/2(12 yd)(7 yd)

  A = 42 yd²

__

8) The area of a parallelogram is given by the formula ...

  A = bh

  A = (8 in)(4 in)

  A = 32 in²

Answer:

First multiply the first equation by 2

2(2x + y = 25)

You'll have

4x + 2y = 50

Rewrite both equations

4x + 2y = 50

3x - 2y= 20

Add from the first equation you'll get

7x = 70... X = 10

Substitute x in one of the equations:

3(10) - 2y = 20

30 - 2y = 20

-2y = -10

y = 5

Answer:

x=2 and y=-6 aka. (2,-6) which is the point of intersection

Step-by-step explanation:

Use elimination to cancel out y by adding the equations:

5x=10

x=2

Plug x=2 into one of the equations and find y:

2(5)+2y=-2

10+2y=-2

2y=-12

y=-6

Therefore, x=2 and y=-6
