Answer:

0.79 = 79% probability that a seed selected at random from the mixed will germinate.

Step-by-step explanation:

Probability of a seed germinating:

85% of 40%(from company A)

75% of 60%(from company B)

Then

[tex]P = 0.85*0.4 + 0.75*0.6 = 0.79[/tex]

0.79 = 79% probability that a seed selected at random from the mixed will germinate.

Let me = slope

m = (13 - 5)/(6 - 2)

m = 8/4

m = 2

The slope is 2.

Answer:

angle abc =140°

and bd bisected by bd so, bd divede angle abc.

angle dbc= angle abc / 2

angle dbc=140°/2

angle dbc=70°

The measure of angle DBC from the given figure is 70°.

The measure of angle ABC is 140°.

The angle bisector in geometry is the ray, line, or segment which divides a given angle into two equal parts.

Angle bisector BD is bisecting angle ABC equally, which is

∠ABC=∠ABD+∠DBC

⇒ 140°=∠DBC+∠DBC

⇒ 2∠DBC=140°

⇒ ∠DBC=70°

Therefore, the measure of angle DBC from the given figure is 70°.

Answer:

y = 4/5x+3.5

Step-by-step explanation:

Answer:

Step-by-step explanation:

y=mx+b

m=(y2-y1)/(x2-x1), we have points (-3,-6) and (2,-2) so

m=(-2-(-6))/(2-(-3))

m=4/5 or 0.8 so our line is now

y=0.8x+b, using point (2,-2) we can solve for b

-2=0.8(2)+b

-2=1.6+b

b=-3.6 so the line is

y=0.8x-3.6 which can also be expressed as

y=4x/5-18/5

Answer:

[tex](x,y) =(-4,-3)[/tex] --- Vertex

[tex]x = -4[/tex] --- Axis of symmetry

Step-by-step explanation:

Given

[tex]y = -6(x + 4)^2 - 3[/tex]

Solving (a): The vertex

For an equation written in

[tex]y = a(x - h)^2 + k[/tex]

The vertex is:

[tex](x,y) = (h,k)[/tex]

By comparison:

[tex]y = a(x - h)^2 + k[/tex]  and [tex]y = -6(x + 4)^2 - 3[/tex]

[tex]-h =4[/tex]       [tex]k = -3[/tex]

[tex]h =-4[/tex]         [tex]k = -3[/tex]  

So, the vertex is:

[tex](x,y) =(-4,-3)[/tex]

Solving (b): The axis of symmetry

For an equation written in

[tex]y = a(x - h)^2 + k[/tex]

The axis of symmetry is:

x = h

In (a):

[tex]h =-4[/tex]

So:

[tex]x = -4[/tex]

9/12 carton

Step-by-step explanation:

Get both fractions to have the same denominator.

So make 3 into 12 by multiplying numerator and denominator by 4.

1×4/ 3×4 = 4/12

Now you can add the fractions.

5/12 + 4/12

= 9/12 Carton

Answer:

x=27

Step-by-step explanation:

Hey there!

the exterior angles of a quadrilateral add up to equal 360

so 360=2x+40+4x+3x+x+50

step 1 combine like terms

2x+4x+3x+x=10x

50+40=90

now we have

360=10x+90

step 2 subtract each side by 90

360-90=270

90-90 cancels out

now we have 270=10x

step 3 divide each side by 10

270/10=27

we're left with

x=27

Answer:

A: 9 seconds

B: 144 ft.

Step-by-step explanation:

A:

Let t = no. of seconds for them to meet

When they meet the sum of their distances is 270 ft, dist = rate * time

16t + 14t = 270

30t = 270

t = 270/30

t = 9 seconds

B:

He ran 9 sec at 16 ft/sec, therefore:

9 * 16 = 144 ft

Answer:

0.887966

Step-by-step explanation:

1. Divide by 3500

(5000/3500)(2^x) = (3^x)

2. divide by 2^x and simplify

10/7 = (3/2)^x.

3. apply 'ln' function

ln(10/7) = xln(3/2)

4. divide ln(3/2)

ln(10/7) / ln(3/2) = x

x = 0.87966
