Answer: 3.75

Step-by-step explanation:

P=0.50, n=15

np= 0.5x15 gives 7.5

n(1-p)= 15x(1-0.5)=7.5

Both are greater than 5

Then Mean, u=np;15x0.5=7.5

Standard deviation, √np(1-p)

15x0.5(0.5)= 3.75

Answer:

Slope=3/2

Slope=rise/run

Graphing this you go up 3 and to the right 2

Y-intercept= 9

Slope intercept form= 3/2x+9

which means the y-intercept is 9

Answer:

-15/6

Step-by-step explanation:

If you look at the first number in each point, the x coordinate, you see the 2nd point is 6 forward from the 1st point. Now the 2nd number is the y coordinate, and you can see it goes down 15 from the 1st coordinate. So y/x is the slope.

Answer: -2 1/2

Step-by-step explanation:

Slope= Yb-Ya/Xb-Xa

In this case= (-8-7)/(4- -2)

This equals -15/6

Simply to -2 1/2

Answer:

FE = 10.30

ED = 7.62

FD = 7.28

Step-by-step explanation:

First, use coordinate system to draw a square that each angle of triangle reach the sides of the square, then use Pythagoras theory to find the length of the sides(c^2=a^2+b^2)

FE = root(9^2+5^2) = root(106) = 10.30

ED = root(3^2+7^2) = root(58) = 7.62

FD = root(2^2+7^2) = root(53) = 7.28

Answer:

[tex]Probability = \frac{7}{253}[/tex]

Step-by-step explanation:

Given

[tex]Orange = 7[/tex]

[tex]Green = 6[/tex]

[tex]White = 1[/tex]

[tex]Black = 7[/tex]

[tex]Yellow = 2[/tex]

Required

Probability of selecting a yellow then orange rock

From the question, we understand that the probability is that of without replacement.

Since the yellow, is first picked.

We need to determine the probability of picking a yellow rock, first.

[tex]P(Yellow) = \frac{n(Yellow)}{Total}[/tex]

[tex]P(Yellow) = \frac{2}{7 + 6 + 1 + 7 + 2}[/tex]

[tex]P(Yellow) = \frac{2}{23}[/tex]

The rock has reduced by 1;

Next is to determine the probability of picking an orange rock

[tex]P(Orange) = \frac{n(Orange)}{Total - 1}[/tex]

[tex]P(Orange) = \frac{7}{7 + 6 + 1 + 7 + 2- 1}[/tex]

[tex]P(Orange) = \frac{7}{22}[/tex]

The required probability is calculated as thus:

[tex]Probability = P(Yellow) * P(Orange)[/tex]

[tex]Probability = \frac{2}{23} * \frac{7}{22}[/tex]

[tex]Probability = \frac{14}{506}[/tex]

[tex]Probability = \frac{7}{253}[/tex]

Answer:

What value of x makes this equation true? 2(4x-3) - 8= 4+2x​  HERE YOU GO!!

Step-by-step explanation:

We need to eliminate one of the variables to solve the other.

4x+5y = 8

2x-3y = 18

I will multiply the second equation by -2.

-2*(2x-3y = 18)

-4x + 6y = -36 and then add the two equations

4x + 5y = 8

-4x + 6y = -36

+ adding here

11y = -24

y = -24/11

substitute x in one of the equations to find y.

2x-3y=18

2x - (3*-24/11) = 18

2x = 126/11

x = 126/22

Answer:

x=6

Step-by-step explanation:

x+7=3x-5

add 5 to both sides

x+12=3x

subtract x from both sides

12=2x

divide by 2 on both sides

6=x

Answer:

Answer is option A

Step-by-step explanation:

The required function [f o g(x)] is -7/√(x + 3).

The domain of the function  [f o g(x)] > - 3.

A function is  the relation between two sets. The first one is called domain and the second one is called range.

Given, f(x) = - 7/x

g(x) = √(x + 3)

Therefore, f o g(x)

= f[g(x)]

= f[√(x + 3)]

= -7/√(x + 3)

Now, the domain of f o g(x) > - 3.
