Answer:
3/8
Step-by-step explanation:
Looking at the bottom row, there are 8 possible outcomes
HHH, HHT, HTH, HTT, THH, THT, TTH, TTT
There are 3 that have exactly 2 heads HHT, HTH, THH,
That means the probability is
P( exactly 2 heads) = number outcomes with exactly 2 heads/total outcomes
=3/8

Help ASAP. This one is also vital to my math grade. I will award 100 points and brainly to whoever can solve this. This is slope intercept form. There is 2 parts to this, will post second part to this when I get the answer for the first part and unlock the second part
Answer:
Slope: 1
Step-by-step explanation:
(9,0) and (0, -9)
m= (y2-y1)/(x2-x1)
m= (-9 - 0)/ (0 - 9)
m= (-9)/(-9)
m = 1
Answer:
Solution given:
coordinates are
(x1,y1)=(9,0)
(x2,y2)=(0,-9)
we have
Slope =[tex] \frac{y2 - y1}{x2 - x1} [/tex]
[tex] = \frac{ - 9 - 0}{0 - 9} [/tex]=1
The slope of a line is 1.

Answer:
1) x = 20
2) Try it yourself based on #1
3) D. BE (it a a segment, it is on the hypotenuse, and it is adjacent to AB)
Step-by-step explanation:
I'll do the first one and you can try the second one
1) Since the two triangles are similar, corresponding parts are similar (CPSP - corresponding parts of similar polygons)
2) Since the corresponding sides are similar, [tex]\frac{AX}{AB} = \frac{XY}{BC}[/tex]
3) We know that AX is 12, AB is 20 (AX+XB=12+8 because of pwp -> part whole postulate), XY is 17, and BC is x
4) Substitute these values into the equation from step 2
[tex]\frac{12}{20} = \frac{12}{x}[/tex]
5) Cross-multiply to get 12x = 12(20)
6) Solve
12x = 240
x = 20

In your own words, explain how natural selection can lead to a change in a population's traits over time.
Step-by-step explanation:
organisms with great adaptive ability are naturally selected to remain in the environment
Answer:
Natural selection leads to evolution because the traits of those who are able to reproduce influence future generations genetics and gradually lead to these passed on traits becoming the normal state of being, thus causing the species in question to evolve.

Step-by-step explanation:
-5Z = 55
What is Z?
Pls help
Answer:
z = -11
Step-by-step explanation:
-5Z = 55
to find z, divide each side by -5
[tex]\frac{-5Z}{-5} = \frac{55}{-5}[/tex]
z = -11
Answer:
Z = -11
Step-by-step explanation:
When dealing with variables, you want to get it alone so it instantly equals the number.
Since Z is being multiplied by -5, you're going to divide -5 because that's the opposite of multiplying--but you have to do it on both sides, not just the one.
Note that when you're dividing or multiplying a negative and positive number, the result with ALWAYS be negative!
-5Z = 55
/-5 /-5
Z = -11
Just in case, we'll plug in -11 for Z and see if it works.
-5(-11) = 55
Note again that when you're multiplying two negatives it cancels out the negative and makes the answer positive!
Hope this helped :)

Answer:
(d) SA = 36π
Step-by-step explanation:
The surface area of a cylinder is ...
SA = 2πr(r +h)
Here, the radius is r=2 and the height is 7, so we have ...
SA = 2π(2)(2+7) = 36π . . . . matches choice D

Dimensions are in meters, so area is in square meters.
MARKING BRAINLIEST TO FIRST PERSON WHO ANSWERS!!! ALSO UPPING POINTS TO 25
Answer:
Approximately 460 ft
Step-by-step explanation:
In any question where we have:
A right triangleAn given angle, andA given sideAnd we're asked to find:
A missing sideWe're gonna be using some trigonometry. The first question we've gotta ask is what we're looking for, and how the angles and sides relate to that. We're given:
The angle of elevation, 49°The distance to the base, 400 ftAnd we're looking for:
The height of the hill, which I'll call h.How do our sides relate to the angle? Well, the 400 ft side is adjacent to 49°, and the side h is opposite. From SOH-CAH-TOA, we can see that the last trig function, tangent, is equal to opposite/adjacent. Let's turn this into an equation to bring it all together:
[tex]\tan{49^\circ}=h/400[/tex]
Solving for h, we find that
[tex]h=400\tan{49^\circ}\approx400(1.15)=460[/tex]
So the heigh of the hill is approximately 460 ft.
Write the slope-intercept form of the equation of a line with a slope of -5/8 that passes through the point (-14,6)
Answer:
y = -5/8x - 11/4
Step-by-step explanation:
Since we already know the slope which is -5/8. This will be the m in the equation.
To find the y-intercept, plug the coordinates into the equation, which is
y= -5/8 + b
6 = -5/8(-14) + b
6 = 35/4 + b
= -11/4 = b
What is the slope of the line that passes through the points (1, 1) and (9,7)?
4/5
3/4
5/4
4/3
