Karla tosses a penny 20 times how many times is the penny most likely to land heads up
Answer:
10times
Step-by-step explanation:
there is a 50/50 chance of both 20 divided by 2 is 10
After tossing 20 times a coin probability of getting heads is equals to 10.
What is probability?" Probability of any event is defined as the ratio of total number of favourable outcomes to the total number of outcomes."
Formula used
[tex]Probability =\frac{Number of favourable outcomes}{Total number of oucomes}[/tex]
According to the question,
Number of times coin tossed = 20
When we toss a coin there only two outcomes Head and Tail.
As per the formula,
Probability of head = 1 / 2
Probability of tail = 1 / 2
Therefore,
Probability of getting head when Karla tossed coin 20 times is equals to 20 / 2 = 10 times.
Hence, after tossing a coin 20 times probability of getting heads is equals to 10 times.

For f(x) = 2x + 1 and g(x) = x2 - 7, find (f+ g)(x).
Answer:
(f + g)(x) = x² + 2x - 6
Step-by-step explanation:
Step 1: Define
f(x) = 2x + 1
g(x) = x² - 7
Step 2: Find (f + g)(x)
(f + g)(x) = 2x + 1 + x² - 7
(f + g)(x) = x² + 2x - 6
In ΔJKL, \text{m}\angle J = (8x+6)^{\circ}m∠J=(8x+6)
∘
, \text{m}\angle K = (2x+2)^{\circ}m∠K=(2x+2)
∘
, and \text{m}\angle L = (4x+4)^{\circ}m∠L=(4x+4)
∘
. Find \text{m}\angle L.m∠L.
Answer:
The measure of angle L is 52
Step-by-step explanation:
Mathematically, in a triangle, the sum of the angles equal 180
So in this case;
J + K + L = 180
So therefore;
8x + 6 + 2x + 2 + 4x + 4 = 180
8x + 2x + 4x + 6 + 2 + 4 = 180
14x + 12 = 180
14x = 180 -12
14x = 168
x = 168/14
x = 12
So to get the measure of angel L, we simply substitute the value x in the equation for L
From the question, L = 4x + 4
So therefore L = 4(12) + 4 = 48 + 4 = 52

Which statement describes the Richter scale?
It cannot account for fault movement during an earthquake.
It measures large earthquakes far from the seismograph.
It estimates the total energy released from an earthquake.
It increases in magnitude as amount of damage increases
Answer:
It increases the magnitude as amount of damage increases
Step-by-step explanation:
Hello, there! My name is Alice and I am here to help you today!
The answer is D)
Here are some notes that will help you with the whole lesson!
Earthquake: Sudden or violent shaking of the ground.
Epicenter: The point of the Earth's surface vertically above the focus of an Earthquake.
Focus: The focus is the place inside the Earth's crust where an earthquake originates.
Magnitude: The great size or extent of something.
Seismic wave: An elastic wave in the Earth.
Seismograph: An instrument that measures and records details of the Earthquake.
The Seismograph is used to find the Focus
Plate movement ⇒ Causes stress.
Stress ⇒ Increasing along faults.
Excess stress ⇒ Leads to rock breaking and an earthquake begins.
Earthquakes begin in the Lithosphere, usually 100km below the surface.
• Earthquakes have two centers
• The focus is the area beneath the surface where rocks beneath break under stress. It is the starting point of an Earthquake
• The Epicenter is the point on the surface directly above the focus
Earthquakes are caused by plate movement. And they begin at the focus.
• Waves carry energy as they travel
• The waves produced by an Earthquake are called Seismic waves
Seismic waves are classified into three categories
« P waves (primary) »
• Arrive first, travel fastest
• Compressed and expand the ground like an accordion
• Travel threw solids and liquids
« S waves (secondary) »
• Arrive after P waves
• Vibrate from side to side and up and down
• Shake structures violently when they reach the surface
• Travel ONLY threw solids
« Surface waves »
• Travel ONLY on the surface
• Were P and S waves move
• Move slowly
• Can produce dramatic ground movement
• May make the ground roll
The Mercalli scale rates an earthquake according to how much damage it causes. And has 12 levels of intensity.
The Mercalli scale rates earthquakes based on the amount of damage they cause.
The Richter scale measures magnitude based on the size of seismic waves.
• Magnitude is determined by measures based on the size of seismic waves.
• Seismic waves are measured by a seismograph
• This scale is good for measuring small, nearby earthquakes
The moment magnitude scale estimates the total energy released by an earthquake.
• Useful for earthquakes of all sizes and distances
• Data collected with seismographs
• Shows what kind of waves were produced and their strength
The Moment of magnitude scale takes into account the movement of rocks along fault lines.
The Sumatra earthquake of 2004 is the third strongest earthquake ever recorded.
• Measured 9.1-9.3 on the Moment magnitude scale
• Measured at the maximum intensity on the Mercalli scale
• Lasted approximately 9 minutes, the longest duration ever measured
• Triggers a massive tsunami and killed approximately 250,000 people
Geologists use Sisemic waves to locate an earthquake's Epicenter.
• Use Siesmograph to measure the difference between the arrival of P and S waves
• Compare data to seismographs from around the world
Earthquakes are caused by stress along faults due to plate movement.
«Traveling Of Energy»
• Seismic waves travel in all directions
• Three types of waves:
• P waves (primary)
• S waves (secondary)
• Surface waves
«Measuring Earthquake Energy»
• Mercalli scale
• Richter scale
• Moment magnitude scale
«Locating The Epicenter»
• Distance of epicenter measured from at least three seismographs
• Location of the epicenter is where three measurements overlap

Here's an easy question. Gina bought 2.5 pounds of peaches that cost $1.38 per pound at the grocery store. Amy went to the local farmer’s market and purchased 3.5 pounds of peaches at $0.98 per pound. Who spent more money, and how much more?
A. Gina, $0.20
B. Gina, $0.02
C. Amy, $0.20
D.Amy, $0.02
Answer:
B, Gina, $0.02
Step-by-step explanation:
Per pound is $1.38, so split it in half to get $0.69 for half a pound.
Then you have 1.38 + 1.38 + 0.68 = $3.45 total for Gina.
Per pound is $0.98, if you split that in half you get $0.49 for half a pound.
Add it up, 0.98 + 0.98 + 0.98 + 0.49 = $3.43.
You can see Gina spent more, and then you subtract 3.43 from 3.45 and get $0.02.
Which of the following is not a function?
A{ (0,1), (1,2), (2,3), (3,4)}
B.{(0,2), (1,3), (4,3), (1,2)}
C.{(1,3), (4,2), (2,0), (3,4)}
D.{(1,2), (2,2), (3,2), (4,2)}
Answer:
B. {(0,2), (1,3), (4,3), (1,2)}
Step-by-step explanation:
A relation is not a function if the same input value maps to multiple output values. Essentially, if any x is repeated, it is not a function.
The second set, {(0,2), (1,3), (4,3), (1,2)}, has x-values of 0, 1, 4, 1, so 1 is repeated. It is not a function.

Find the coordinates of the midpoint of segment LP with endpoints: L(4, 2) and P(0, 2)
Step-by-step explanation:
here,
midpoint of line segment LP
=( X1 +X2÷2 , Y1 + Y2÷ 2)
=(4+0÷2 , 2+2 ÷2)
=(4÷2 ,4÷2)
=(2,2)
Therefore the midpoint of segment LP with L (4,2) and P (0,2) = (2 ,2).
